HIGH VOLTAGE CIRCUIT BREAKER HAVING FUNCTION OF PREVENTING OPENING AND CLOSING SURGE

摘要

The invention of the power distribution unit can overcurrent, overvoltage detection on high-voltage circuit breaker to interrupt the current More specifically, as in a step-by-step by providing a high voltage to 0V at the switching to the voltage connected to the voltage distributor with take-minute or one terminal of the two portions of the adjacent terminal has been drawn out from the take-off distribution for distributing the voltage applied from the high-voltage bus bar will be opened and closed by the voltage drop across the surge to avoid the opening of the high-voltage circuit-breaker having a surge protection function. ; To this end the present invention is connected to at least one of transmission and distribution lines to divide the high-voltage bus bar voltage transmission and distribution and voltage distribution for; The voltage connected to the take-minute or one terminal of the two positions of the plurality of neighboring terminals drawn out from the take-up step-by-step transfer is distributed doedoe and switching unit for switching the transmission and distribution voltages; Is coupled to one side of the current or the voltage over-current voltage distribution section, and detection section for detecting a voltage; If the fault is detected by the detector control unit for opening and closing the transmission and distribution voltage through said switching; comprises a
