1·The operation procedures to move the withdrawable circuit breaker in and out of the compartment are as same as that for withdrawable circuit breaker without earthing switch.
手车推入柜内或手车从柜内退出的操作程序与无接地开关之断路器的操作是完全相同的，固不再繁述。
2·Reasonable laying space and effective screen earthing, which can reduce the static electricity coupling interference.
合理的敷设间距与有效的屏蔽接地，可以减少静电耦合干扰。
3·Communication network is concerned on system power supply, wire select, network top and earthing.
通信组网主要涉及系统供电、线缆选择、线路拓扑和接地等。
4·The electrical elements connected include circuit breaker disconnector and earthing switch current transformer voltage transformer lightning arrester bus etc.
连接的电气元件有断路器、隔离开关与接地开关、电流互感器、电压互感器、避雷器、母线等。
5·Therefor by earthing connected net of set, it reduce earthing resistance, make the electricity discharge in earth prompt without dangerous overvoltage.
这样通过延伸机组的接地网进一步降低接地电阻，使雷电流迅速流散入大地而不产生危险的过电压。
