摘　　要：通过继电器线包与继电器开关的串并联组合实现的电路,当测试过程出现异常动作或状态时,电路状态可能会根据当前状态与开关动作改变,出现与设计目标背离的状态,引入潜通路。本文根据继电器电路网络的电气特性,结合图论的理论设计分析模型,建立状态方程,确定电路不同初始状态下的各种响应及最终电路状态,依据最终稳态查找潜在通路,发现电路设计薄弱处,以便提高电路的安全性与可控性。The combination of serial and parallel circuit function is achieved by applying a relay line packet and relay switch.When abnormal actions or states occur in testing process,circuit state may be changed due to the current state and the switching action,which departs from the goal state and results in introducing the potential pathway.According to the electrical characteristics of the relay circuit network,based on the graph theory analysis model,the state equation is established to determine the response of the circuit under different initial conditions and the final circuit state.According to the final steady state to find potential pathways,the circuit design of the weak point is found to improve the safety and controllability of the circuit.
