CN207069564U 一种弧光保护加速变压器复压闭锁过流保护系统 失效 - 放弃

一种弧光保护加速变压器复压闭锁过流保护系统
摘要：
本实用新型公开了一种弧光保护加速变压器复压闭锁过流保护系统，包括整定值输入电路、转换解码电路、弧光保护信号输入电路、处理器和输出电路；整定值输入电路、转换解码电路以及弧光保护信号输入电路的输出端均与处理器的输入端连接，处理器输出端与输出电路的输入端连接，输出电路输出端输出保护开出量。本实用新型能够有效缩减复压闭锁电流保护动作时间，减少此故障状态下变压器所受短路冲击，减少短路故障对变压器的损害。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The utility model discloses an arc protection transformer with higher speed presses shutting overcurrent protection system again, including setting value input circuit, conversion decoding circuit, arc protection signal input circuit, treater and output circuit, setting value input circuit, conversion decoding circuit and arc protection signal input circuit's output all is connected with the inputof treater, and the treater output is connected with output circuit's input, the output circuit output protection volume of leaving. The utility model discloses can effectively reduce compound pressure latching current operate time of protection, the short -circuit impact that the transformer receives under this malfunction of reduction reduces the harm of short -circuit fault to the transformer.
