Research of the Undervoltage Tripper with Overvoltage Protection Function

Abstract:

The undervoltage tripper is a protection accessory of the low voltage apparatus and can turn off the circuit-breaker automatically when the power occurs lowering out off the given range. As a result of electrical network quality and manufacture procedure and so on, the failure rate of the circuit-breaker’s undervoltage tripper is high and always solved difficultly. This paper proposes one kind of adaptive undervoltage tripper with overvoltage protection function. It can adapt the supply voltage change automatically, absorb overvoltage, block the undervoltage tripper’s coil voltage, cause the operating region of the undervoltage tripper without high voltage dead area and improve the circuit-breaker work’s reliability.
