The main role of isolation switch: 1. for isolated power, high-voltage electric equipment maintenance equipment and disconnect Yancheng isolation switch, there is disconnect between making an obvious point to be visible. 2. isolating switch and circuit breaker coordination necessary system operating mode switching operation carried out in order to change the system to run wiring. 3. to turn on or off a small current circuit. It must be emphasized, whether opening or closing operations should not be carried out with a load or load isolation switch within the permissible operating range. For this reason, before operating the isolation switch, you must first check the isolation switch connected in series with the circuit breaker, should really be in the off position. Such as load isolation switch with the provisions of the transformer capacity range, you must first stopped all low voltage transformer load isolation switch Zhenjiang, then make it load and then pull the isolation switch; when the power, check the transformer low voltage side of the main indeed switch in the off position before co-isolation switch.
