Filed: 1983-07-20
Abstract: PURPOSE:To detect a transient phenomenon at least within a half cycle before a changing operation of an on-load tap changer and facilitate locking the changing operation of the on-load tap changer by a method wherein an advancing phase or a lagging phase is detected in accordance with a time sequence of zero point of voltage rising, zero point of voltage falling, zero point of current rising and zero point of current falling. CONSTITUTION:A state that all DF/Fs 47-54 are reset, in other words, all respective output signal lines 55-62 are at L level is assumed. In a normal state, if the phase is advanced, i.e. current IL is ahead of voltage US, when a derivative pulse gamma is at H level, U is at H level and, when a derivative pulse beta is at H level, I is at H level and, when a derivative pulse delta is at H level, U is at L level and, when a derivative pulse alpha is at H level, I is at L level and the derivative pulses are generated with the time sequence of gamma beta delta alpha gamma beta .... Because all signal levels of the output signal lines 55-58 are H, an AND-gate 63 transmits an H level signal to an output signal line 65 so that the level of an advancing signal LEAD becomes H. In other words, the advanced state is detected.

Abstract: PURPOSE:To control the discharge amount of powder and to decrease the cost of installation and equipment by detecting the level of the powder deposited in a hopper with a vibration type level sensor, and opening and closing a shutter at a constant discharging speed. CONSTITUTION:The level of deposit powder which is inputted from a vibrating plate 11 is detected with a vibration type level sensor 12 which is provided at the specified level position in a hopper 10. The time intervals for discharging are set so that the intervals become long sequentially in first - fourth timer T1 - T4. The timer T1 - T4 are connected to a control circuit 15. For example, when the detected signals from the sensor 12 are received until the time of the timer t1 is up, an excessive-discharge-amount signal indicating the excessive amount of the powder in the hopper 10 is outputted from the circuit 15. Similarly, a signal for delaying the discharge speed, a signal for keeping the discharge speed, a signal for accelerating the discharge speed and a signal for too little discharge are appropriately outputted from the circuit 15 based on the detecting signals from the sensor 12 and the preset times of the timer T1 - T4. A shutter 14 is opened and closed through an actuator 13. Thus, the discharge amount of the powder per unit time from the hopper 10 is controlled.
