Automatic transfer switch, as its name implies, is one or more switches, switches, appliances and other necessary appliances. It can monitor the circuit of the power supply in real time, and the automatic transfer switch has an emergency power supply in addition to the common power supply.

Double power automatic switch conditions can automatically judge the power of two, if there is failure or outage when the normal power supply, dual power automatic switch will automatically switch to the standby power supply immediately above the go, so that you can keep the normal power supply, so the need to use electrical equipment will continue normal operation.

The use of double power automatic switch is very extensive, such as elevator, banks and hospitals would not be able to cut these occasions there is usually automatic transfer switch, because of power failure, it will cause huge economic losses, or even a threat to the safety of human life.

The structure of double power automatic switch is composed of controller, conversion mechanism and body. The controller is very important. It can be said that the controller is the brain of double power automatic switch. It can control the switch of double power supply and switch the two power supply. The switching mechanism is composed of a drive mechanism and a transmission mechanism, the function of which is to realize non breaking and connection, and also to determine the mechanical reliability of the automatic transfer switch. As for the automatic transfer switch, the main body of the switch is composed of contact, contact mechanism and arc extinguishing cover, which directly determines the electrical characteristics of the automatic transfer switch of double power supply.
