摘　　要：气体绝缘金属封闭开关设备(GIS),控制回路由接触器、继电器组成。由于电磁接触器、继电器的结构特点,触点在状态转换的过程中的动作时间范围从几毫秒到几十毫秒不等,使得理论上进行电路分析时可行的逻辑控制功能,在实际产品运行中可能出现问题。通过GIS设备中高压隔离、接地开关控制回路的案例,使用接触器的时序分析解决控制回路的设计问题,探讨GIS控制回路设计缺陷的识别方法。The control circuit of gas insulated metal enclosed switchgear(GIS)is composed of contactor and relay.Due to the structural characteristics of electromagnetic contactors and relays,the action time range of contacts in the process of state conversion ranges from a few milliseconds to tens of milliseconds,which makes the feasible logic control function in circuit analysis theoretically possible,and there may be problems in the actual product operation.Through the case of high-voltage isolation and grounding switchgear control circuit in GIS equipment,this paper uses the timing analysis of contactor to solve the design problem of control circuit,and discusses the identification method of GIS control circuit design defects.
