Title: Line protection relay device
Inventor: SASAKI HIROSHI
IPC: H02H7/26
Filed: 1992-09-24
Abstract: PURPOSE:To detect, in a high detection sensitivity, the accident occurring in the line including a transmission line and a branching line thereof within the protection object section under the condition that there is no input of an external accident detecting signal when an internal accident detection signal is inputted. CONSTITUTION:When an internal accident occurs at the accident point F1, a trip allowable output signal is outputted from a current differential decision part 104 and it is also outputted from a voltage relay 105. Thereby, a cut-off command signal is outputted from an AND gate 107 and the breakers 41, 42 are tripped. Meanwhile, even when the trip allowable output signal is outputted from the current differential decision part 104 by an accident in the area outside the protection object section, the condition of logical AND of the AND gate 107 is not satisfied and the cut-off command signal is not outputted. As explained, since whether an accident has occurred or not in the protection object area is decided based on the condition of electrical signal of the transmission line 11 and the signal from the direction relays 300, 400, an accident in the protection object area can be detected with a high sensitivity.

Title: Overcurrent protective circuit
Inventor: KAJI YOSHIHISA
IPC: H02H9/02
Filed: 1992-09-25
Abstract: PURPOSE:To prevent the overload of the title circuit by a method wherein the input of an operational amplifier, for current balance control use, which controls a transistor which devides the electric current of an electronic load device for testing a power- supply device into a plurality of electric currents is operated and amplified, the reciprocal number of the output voltage of the power-supply device and the sum of output currents are operated and amplified and a reference voltage for control use is controlled. CONSTITUTION:The output voltage Vin of a device under test (a power supply device) 10 is divided into transistors Trs 2-1 to 2-n and resistances R5-1 to R5-n. The output voltage Vin is converted 4 into a reciprocal number. A value which is proportional to the sum of output currents is found from a resistance R11 and input to an operational amplifier 5. The output of the operational amplifier 5 and a reference voltage Vr for control use are operated by an operational amplifier 1 for control input use. Its output is input to operational amplifiers 3-1 to 3-n for current balance control use and operated. Its output is added to gates for the Trs 2-1 to 2-n. When an overcurrent flows to the Trs 2-1 to 2-n, the output voltage of the device 10 under test is lowered forcibly. Thereby, the Trs 2-1 to 2-n of an electronic circuit for test use are protected from the overcurrent.
