The invention discloses a charging gun contactor interlocking circuit and a charging pile, and belongs to the field of power electronics. The charging gun contactor interlocking circuit is electrically connected with the first charging gun contactor, the second charging gun contactor and the power distribution contactor. According to the charging gun contactor interlocking circuit, it can be determined that the first charging gun contactor, the second charging gun contactor and the power distribution contactor are in the pull-in state or the turn-off state by detecting the first signal, the second signal and the third signal. At the same moment, the charging gun contactor interlocking circuit controls the other contactor to be disconnected to form interlocking when two signals control the corresponding contactor to be attracted, the risk of short circuit of the output end is greatly reduced, and the problems of complicated wiring in the circuit and complicated contactor type selection are solved by utilizing a hardware logic interlocking structure.
本申请公开了一种充电枪接触器互锁电路及充电桩,属于电力电子领域。充电枪接触器互锁电路分别与第一充电枪接触器、第二充电枪接触器以及功率分配接触器电连接。根据本申请的充电枪接触器互锁电路,通过检测第一信号、第二信号和第三信号可以确定第一充电枪接触器、第二充电枪接触器和功率分配接触器处于吸合状态或者关断状态。在同一时刻,充电枪接触器互锁电路在有两个信号已经控制对应的接触器吸合时,控制另外一个接触器保持断开,形成互锁,极大降低了输出端短接的风险,且利用硬件逻辑互锁结构,避免了电路内部接线繁杂且接触器选型复杂问题。
