    Tips: Structure of automatic transfer switch

    The automatic switch has a wide range of applications, such as elevators, banks and hospitals, where the power failure is absolutely unwanted. Once the power is cut off, it will cause huge economic losses and even endanger human safety.

    The automatic switch is mainly composed of a controller, a conversion mechanism and a body. The controller is very important, which is the same as the brain of the automatic changeover switch. It can control the switching between the two power sources. The conversion mechanism is composed of a drive mechanism and a transmission mechanism. Its role is to achieve non-stop disconnection and connection, and also determine the mechanical reliability of the automatic transfer switch. As for the body of ATS transfer switch, it is composed of contacts, contact mechanism and arc extinguisher, which directly determines the switch electrical characteristics.
