具有跳闸检测功能的站用变压器分接开关保护装置
摘要：
本实用新型公开了一种具有跳闸检测功能的站用变压器分接开关保护装置，包括分接开关保护电路和跳闸检测电路，跳闸检测电路包括中间电磁继电器和信号匹配电路，中间电磁继电器的线圈串联接入分接开关保护电路，中间电磁继电器的开关与信号匹配电路相连。本实用新型为分接开关保护提供跳闸检测功能，能够方便检察人员快速判断跳闸是断路器本身故障或是变压器分接开关保护动作引起的，使排查故障方便快捷。
摘要（英）：

The utility model discloses a station transformer tap switch protection device with a tripping detection function. The device comprises a tap switch protection circuit and a tripping detection circuit. The tripping detection circuit comprises an intermediate electromagnetic relay and a signal match circuit. The coil of the intermediate electromagnetic relay is connected in series with the tap switch protection circuit. The switch of the intermediate electromagnetic relay is connected with the signal match circuit. The device provides the tripping detection function for tap switches, and provides convenience for detection personnel to rapidly determine whether tripping is caused by faults of a circuit breaker or protection operation of the transformer tap switch, so trouble shooting is convenient and fast.
