摘要： A switching controller for circuit breaker in which a switching control arithmetic operation unit performs arithmetic operations to determine for each circuit breaker a synchronous delay count value which is sent to each switching command control unit of the corresponding circuit breaker, which upon receiving a switching command signal from a superordinate device, counts the synchronous delay count value D, to turn on a semiconductor switch of the switching command output unit after counting completes. The switching command signal (circuit breaker drive current) is output after the synchronous switching control to the circuit breaker drive coil of the circuit breaker. The switching controller can implement cost saving and space saving, even if switching of a circuit breaker in a lower branch system, such as a power distribution system, is controlled.

摘要： The system of the invention includes a circuit breaker switching control section (100) and a setting control section (700) connected therewith through a communication network (500). The circuit breaker switching control section (100) transmits a circuit breaker state quantity acquired by a signal input section (120) through the communication network to a set value calculation section (740) of the setting control section (700). The set value calculation section (740) of the setting control section calculates a set value to be set in the switching control section (100) of the circuit breaker, using the state quantity of the circuit breaker that was transmitted thereto. The setting control section (700) transmits to the circuit breaker switching control section the set value calculated by the set value calculation section (730) through the communication network. A switching control calculation processing section (140) provided in the switching control section of the circuit breaker corrects the circuit breaker switching actuation time in accordance with this set value and calculates a delay time in respect of the zero-cross point in accordance with this corrected switching actuation time and power system period.

摘要： The MPU for switching control arithmetic operation 210 in the switching control arithmetic operation unit 200 performs arithmetic operations to determine a predetermined delay time (synchronous delay count value D) for each circuit breaker 1100. The synchronous delay count value is sent to each switching command control unit 400 of the corresponding circuit breaker. The hardware counter 20 of the switching command output control unit 450, for the switching command signal received from the superordinate device 2000, counts the synchronous delay count value D, which is the delay time. When the semiconductor switch of the switching command output unit 10 turns ON after counting completes, the switching command signal (circuit breaker drive current) after the synchronous switching control is output to the circuit breaker drive coil 1110 of the circuit breaker 1100. A switching controller for circuit breaker and a switching control system for circuit breaker are provided, which can implement cost saving and space saving, even if switching of a circuit breaker in a lower branch system, such as a power distribution system, is controlled.

摘要： An overvoltage suppression device which suppresses overvoltage that occurs when breakers which turn on/off the connection between a power source bus and a power transmission line, are turned on after the breakers are turned off. The overvoltage suppression device measures the waveform of voltage on the side of the power source and the voltage on the side of the power transmission line, and extracts the waveform of a component in a predetermined frequency band on the basis of the waveform obtained by multiplying the wave shape of the voltage on the side of the power source by the waveform of the voltage on the side of the power transmission line. The breakers are turned on on the basis of a cycle wherein the waveform is peaked.
