The correct sequence of operation of the disconnector – ifm

Create Date: 2024-8-30 12:03:23|Source: IFM/ifm

The operation of the barrier switch should focus on avoiding pulling and closing the knife switch with load, and avoiding closing the knife switch with grounding.

                                    The correct sequence of operation of the disconnector – ifm

The correct order of operation is:

In the order of power transmission operation, check that the circuit breaker is in the open position, first close the bus (power supply) side knife switch, then close the line (load) side knife switch, and finally close the circuit breaker.

In the order of power failure operation, first swing the circuit breaker, check that the circuit breaker is indeed open, then swing the line (load) side switch, and finally open the bus (power supply) side switch. It is also possible to use the knife switch for inverted bus operation (equipotential operation).

1. The barrier switch can only be operated when it is not loaded or the load is within the allowable range of the barrier switch. That is, the circuit breaker must be in the disconnected state when the barrier switch is operated.

2. Pull out the positioning pin during the operation, the opening and closing action should be decisive and rapid, do not use too much force at the end, and be sure to lock it with the positioning pin after the operation is completed, and visually check whether the moving contact position meets the requirements.

3. If there is a misoperation of the load cutting and switching switch, it is necessary to be calm to avoid misoperation in the opposite direction.
