Hereinafter, a monitoring system of a power device according to some embodiments of the present disclosure will be described.

The same reference numerals are allocated to the same components of the monitoring system of the power device according to the present disclosure as those of the conventional power device.

FIG.5is a perspective view showing a configuration of a monitoring system of a power device according to an embodiment of the present disclosure.

Further,FIG.6is a perspective view illustrating a state in which the circuit breaker body is disconnected from the cradle in the monitoring system of the power device according to an embodiment of the present disclosure.

Referring toFIG.5andFIG.6, the monitoring system of the power device according to the present disclosure includes the cradle100having the cradle terminal110, the girder300fixed to the cradle100, the truck400which is movable so that a spacing between the girder300and the truck400may be adjusted, and the circuit breaker body200loaded on the truck400so as to contact or be disconnected from the cradle terminal110.

Further, in the monitoring system of the power device according to the present disclosure, the circuit breaker includes the circuit breaker body200, the girder300and the truck400.

Further, the monitoring system of the power device according to the present disclosure includes at least one position detected area portion500and500′ extending in a corresponding manner to a movement range of the truck400and formed on the circuit breaker body200or the girder300, at least one sensor module600and600′ that is fixedly installed on the cradle100or the truck400so as to detect movement characteristics of the position detected area portion500and500′ in real time, a controller800configured to receive the movement characteristics of the position detected area portion500and500′ sensed by the sensor module600and600′ and to detect movement characteristics of the circuit breaker body200based on the received movement characteristics, and a display900for outputting the movement characteristics of the circuit breaker body200detected by the controller800.

In this case, various wired/wireless communication networks may be applied to connection between the sensor module600and600′ and the controller800and connection between the controller800and the display900.

Further, the display900may be embodied as an administrator's portable terminal.

In one example, in the monitoring system of the power device according to the present disclosure, the disconnection position means a position in which the circuit breaker body200is spaced from the cradle terminal110by the maximum spacing and thus is electrically disconnected from the cradle terminal110.

That is, the disconnection position refers to a state in which a spacing between the girder300and the truck400is minimized.

Further, in the monitoring system of the power device according to the present disclosure, the contact position means a position in which the circuit breaker body200approaches the cradle terminal110at the maximum level and electrically contacts the terminal110.

That is, the contact position refers to a state in which the spacing between the girder300and the truck400is maximized, and a terminal formed on the circuit breaker body200is coupled to the cradle terminal110.

Further, in the monitoring system of the power device according to the present disclosure, an operation position means a state in which the spacing between the girder300and the truck400is adjusted in a process in which the body is being displaced from the contact position to the disconnection position or from the disconnection position to the contact position.

The girder300includes a pair of handle bars310formed on a front face thereof, support ribs320respectively formed at both opposing sides thereof, and a spindle330having one end rotatably coupled to a center of the front face thereof.

More specifically, the handle bar310may refer to a part gripped by an operator when the girder300and the truck400are mounted to or disconnected from the cradle100and be formed in various shapes.

Further, the girder300is fixed to the cradle100while each of the support ribs320is inserted into and fixed to each of both opposing sides of the cradle100.

Further, the spindle330is coupled to the truck400such that one end of the spindle is coupled to a central portion of the girder300and the other end thereof faces the cradle terminal110.

Thus, when the spindle300rotates clockwise or counterclockwise, the spacing between the girder300and the truck400is adjusted.

Further, the rotation of the spindle330may be achieved by an operator inserting a handle to a hole formed in a front face of the girder and manually rotating the handle, or may be automatically achieved by a driving motor.

In one example, the movement characteristics of the circuit breaker body200output from the display900may include at least one of a movement distance of the circuit breaker body200, a remaining distance thereof to the contact or disconnection position, a movement speed thereof, change in the movement speed thereof, and a contact amount between the circuit breaker body200and the cradle terminal110.

More preferably, the movement characteristics of the circuit breaker body200output from the display900may be output in a form of a graph or a figure including a numerical value so that an administrator may easily identify the same.

Further, when the circuit breaker body200is in the contact position, the controller800may generate a notification alert when the contact amount between the circuit breaker body200and the cradle terminal110exceeds a preset allowable range of the contact amount, and may output the generated notification alert to the display900.

In one example, sizes of the circuit breaker body200and the cradle100may vary based on applications thereof. Thus, when the sizes of the circuit breaker body200and the cradle100and specifications of the cradle terminal110are input to the controller800, the controller800may be configured to automatically extract the contact amount between the circuit breaker body200and the cradle terminal110based on a distance between the circuit breaker body200and the cradle100.

Accordingly, the monitoring system of the power device according to the present disclosure may minimize heat generation, device damage, safety accidents, etc. caused by incorrect coupling between the circuit breaker body200and the cradle terminal110.

Further, at least two values of the same type of the movement characteristic among the movement characteristics of the position detected area portion500detected by the sensor module600may be detected. In this case, when a difference between the detected values exceeds a preset error tolerance, the controller800may generate a notification alert and output the same to the display900.

More specifically, the controller800may compare movement characteristics respectively sensed by a plurality of sensor modules600respectively facing a plurality of position detected area portions500with each other. When the movement characteristics are different from each other based on the comparing result, the controller800may output the notification alert to the display900, such that the administrator may be guided to inspect the position detecting means including the position area sensor500and the sensor module600and an entirety of the power device.

Accordingly, the monitoring system of the power device according to the present disclosure may identify an error in the movement characteristics of the circuit breaker body200caused by an error in the position detecting means, a defect in the sensor module600or a transfer failure of the truck400in a short time.

In one example,FIG.7andFIG.8are perspective views showing a girder and a truck at a disconnection position and a contact position in a monitoring system of a power device according to an embodiment of the present disclosure, respectively.

Further,FIG.9is a perspective view showing a position bar in a monitoring system of a power device according to an embodiment of the present disclosure.FIG.10is a perspective view showing each of a top face and a bottom face of a sensor module in a monitoring system of a power device according to an embodiment of the present disclosure,

Referring toFIG.7toFIG.10, in the monitoring system of the power device according to the present disclosure, the position detected area portion500may be formed on a position bar350having one end coupled to the girder300and the other end acting as a free end facing the cradle terminal110. The sensor module600may be fixedly coupled to one side of the truck400so as to detect movement characteristics of the position detected area portion500.

More specifically, the position bar350may extend in parallel to the spindle330such that one end of the position bar350is coupled to the girder300, and the other end thereof acts as the free end.

Further, the sensor module600may include at least one of a non-contact type sensor610disposed to face the position detected area portion500and a contact type sensor620disposed to contact the position detected area portion500.

In this case, the non-contact type sensor610may be embodied as an optical sensor and may be configured to detect a shade, a distance, a shape, etc. of a predefined area of the position detected area portion500.

Further, as shown in (b) ofFIG.10, the contact type sensor620may be embodied as an FPCB (Flexible Printed Circuit Board) or an elastic member extending toward the position bar350and thus contacting the position bar350.

In one example, the position detected area portion500may extend along the movement range of the truck400as described above. More preferably, as shown in (a) ofFIG.9, the position detected area portion500may be embodied as a position sticker510having a shade varying depending on a position, such as a gradation sticker.

In this regard, the position sticker510may have a polygon shape such as a triangle having an area size varying in the movement direction of the circuit breaker body200, as shown in (b) ofFIG.9.

In one example, the position detected area portion351may be formed as a position inclined portion520as shown in (c) ofFIG.9. The position inclined portion520may be formed to protrude upwardly beyond the top face of the position bar350. Alternatively, the position inclined portion520may be formed to be recessed downwardly beyond the top face of the position bar350.

In this regard, a gradation tape whose a shade varies as described above may be attached to a top face of the position inclined portion520.

In one example, the position detected area portion500may include a plurality of position protrusions530arranged and spaced from each other by a predefined spacing as shown in (d) ofFIG.9.

More preferably, the numbers, shapes, positions of the position protrusions530may vary in the movement direction of the truck400so that the position of the circuit breaker body200may be detected by the sensor module600.

Further, the position detected area portion500may include a combination of the position protrusions530and the position tape510.

In one example, in the monitoring system of the power device according to the present disclosure, the truck400may include a plurality of position bar guides430adjacent to or in contact with both opposing side faces of the position bar350.

Further, as shown inFIG.6, the position bar guide430is preferably provided with a brush-type cleaner700capable of removing dust or foreign substances deposited on the position detected area portion500.

Accordingly, the monitoring system of the power device according to the present disclosure may minimize a detection error of the sensor module600due to the foreign material deposited on the position detected area portion500.

Further, the contact type sensor620may contact the position inclined portion520and may detect a varying height of the position inclined portion520and thus detect the position of the circuit breaker body200based on the varying height.

In one example,FIG.11andFIG.12are side cross-sectional views at the disconnection position and the contact position in the monitoring system of the power device according to an embodiment of the present disclosure, respectively.

Further,FIG.13is a side view illustrating a position detected area portion in a monitoring system of a power device according to an embodiment of the present disclosure.

Referring toFIG.11toFIG.13, in the monitoring system of the power device according to the present disclosure, the position detected area portion500′ may be formed on a side face of the circuit breaker body200, and the sensor module600′ may be fixedly coupled to an inner side face of the cradle100so as to detect the movement characteristics of the position detected area portion500′.

In this regard, as shown in (a) ofFIG.13, the position detected area portion500′ may be embodied as a position sticker510′ having a shade varying depending on a position, such as a gradation sticker.

Alternatively, the position detected area portion500′ may have a polygon shape such as a triangle having an area size varying in the movement direction of the circuit breaker body200, as shown in (b) ofFIG.13.

Alternatively, the position detected area portion500′ may be formed as a position inclined portion520′ as shown in (c) ofFIG.13. The position inclined portion520′ may be formed to protrude upwardly beyond the side face of the circuit breaker body200. Alternatively, the position inclined portion520′ may be formed to be recessed downwardly beyond the side face of the circuit breaker body200.

In this regard, a gradation tape whose a shade varies as described above may be attached to a top face of the position inclined portion520′.

In one example, the position detected area portion500′ may include a plurality of position protrusions530′ arranged and spaced from each other by a predefined spacing as shown in (d) ofFIG.13.

More preferably, the numbers, shapes, positions of the position protrusions530′ may vary in the movement direction of the truck400so that the position of the circuit breaker body200may be detected by the sensor module600.

Further, the position detected area portion500′ may include a combination of the position protrusions530′ and the position tape510′.

In one example, in the monitoring system of the power device according to the present disclosure, the position detected area portion500′ may be formed on the inner side face of the cradle100, and the sensor module600′ may be formed on the side face of the circuit breaker body200.

However, it is more preferable that the sensor module600′ is disposed on the inner side face of the cradle100as described above such that connection, control, and inspection of the sensor module600′ is facilitated.

In this regard, when the sensor provided in the sensor module600′ is embodied as an optical sensor including wireless communication means, the position detected area portion500′ may be formed on an inner side face of the cradle100, and the sensor module600′ may be disposed on the side face of the breaker body200, according to a design specification.

More specifically, the cradle terminal110which the circuit breaker body200electrically and mechanically contacts may include terminals of three-phases (R, S, T). In this case, when contacts between the circuit breaker body200and these terminals110fail to occur concurrently, damage to the power device and power accident may occur.

Therefore, when the cradle terminal110which the circuit breaker body200electrically and mechanically contacts may include terminals of three-phases (R, S, T), the power device for continuously detecting extended and retracted positions according to the present disclosure may be configured such that the position detected area portion500′ is formed on each of both opposing side faces of the circuit breaker body200and accordingly, the sensor module600′ is formed on each of both opposing inner side faces of the cradle100so that contacts or disconnections between the circuit breaker body200and these terminals110occur concurrently.

Further, when the positions of the circuit breaker body200respectively detected by the two sensor modules600′ fail to coincide with each other, the display900may output a notification alert.

Accordingly, in the monitoring system of the power device according to the present disclosure, the circuit breaker body200may contact or may be disconnected from the cradle terminal110to prevent device damage and power accidents.

In one example, the sensor module600′ may include at least one of a non-contact type sensor610′ disposed to face the position detected area portion500′ and a contact type sensor620′ of a roller type contacting the position detected area portion500′, as shown inFIG.6.

Further, a brush or roller type cleaner700′ may be disposed in front or rear of the sensor module600′ so as to remove dust or foreign substances adhering to a surface of the position detected area portion500′.

In one example, the cleaner700is more preferably installed in front of the sensor module600.

When the cleaner700is adjacent to the cradle terminal110, arc may occur such that the cleaner700may be damaged or an electrical problem may occur. Thus, the cleaner700may be spaced from the cradle terminal110by a maximum spacing.

The present disclosure has been described above with reference to the illustrated drawings. However, the present disclosure is not limited to the embodiments and drawings disclosed in the present specification. It is obvious that various modifications may be made by those skilled in the art within the scope of the technical idea of the present disclosure. In addition, although effects according to the configurations of the present disclosure are not explicitly described while describing the embodiments of the present disclosure, it is natural that the predictable effects from the configurations should also be appreciated.
