The invention discloses a power switching system and a contactor matrix logic interlocking method thereof. The power switching system comprises N 1-input N-output modules and a power switching centralized control board, one path of positive and negative pole input in each one-input N-output module is divided into N paths of positive and negative pole output through N pairs of positive and negative pole contactors, and the N pairs of positive and negative pole contactors are in control and communication connection with the power switching centralized control panel through a wire harness collector; the N paths of positive and negative electrode outputs in the N 1-input N-output modules are connected in parallel in a one-to-one correspondence manner and are finally summarized into N paths of positive and negative electrode total outputs. According to the invention, all contactors in the power switching system are connected to the power switching centralized control panel through the wire harness collector, the contactors feed back level signals, and the power switching centralized control panel issues control signals for opening and closing contactor coil contacts according to the level signals to realize electrical logic interlocking. The safety risk problem caused by short circuit of multiple output loops, untimely protection and the like due to communication delay or asynchronous problems is solved.

    本发明公开了一种功率投切系统及其接触器矩阵逻辑互锁方法,包括N个1进N出模块和一个功率投切集中控制板;每个1进N出模块中的一路正负极输入通过N对正负极接触器分为N路正负极输出,且N对正负极接触器通过一线束汇集器与功率投切集中控制板控制及通信连接;N个1进N出模块中的N路正负极输出一一对应并联并最终汇总为N路正负极总输出。本发明通过将功率投切系统中所有的接触器通过线束汇集器,连接到功率投切集中控制板,通过接触器反馈电平信号,功率投切集中控制板根据电平信号进行接触器线圈触点开闭的控制信号下达实现电气逻辑互锁,解决通信延时或者不同步问题导致的多条输出回路短接、保护不及时等引发的安全风险问题。
