100 amp changeover switch Dual-power automatic switching switch is an electrical component which plays the role of switching main and standby power supply in low-voltage distribution system, and plays an irreplaceable role in distribution system. Many important places are equipped with dual power automatic switch. So, what is the working principle of the dual power automatic switch?
The standby power supply is called “hot standby” if it has electricity all the time. Important users should be like this. If the standby power supply is the delayed power generation of the engine, the dual power automatic switching switch also plays a role. It cuts off the circuit of the municipal electricity and prepares the path for the generator self-generation. In particular, it is very important to cut off the municipal electric circuit. First, it is to prevent the self-generated electricity from retransmitting to the municipal electric network. Second, it is to prevent the sudden incoming electricity from the municipal electric power and the non-synchronous grid connection between the self-generated electricity and the municipal electric power, which causes the tripping of both sides.
