SWQ2 double power automatic transfer switch, as its name implies, is composed of one or more switch electrical appliances and other necessary electrical appliances, in the electrical industry often said "double power transfer switch" or "double power switch" and double power automatic transfer switch belong to the same product. The dual power automatic transfer switch can automatically judge the good or bad situation of the two power supplies. If the common power supply fails, the dual power automatic transfer switch will automatically switch to the standby power supply immediately, so that it can normally supply power to the load.

SWQ2 double power automatic transfer switch structure is mainly composed of controller, conversion mechanism, body; The controller is very important, it can be said that the controller is the brain of the double power automatic transfer switch, it can control the double power automatic transfer switch for two power conversion; Conversion mechanism is composed of driving mechanism and transmission mechanism. Its function is to realize non-stop breaking and switching, and can also determine the mechanical reliability of the double power automatic transfer switch; The body part is composed of contact head, contact head mechanism and arc extinguishing chamber; It directly determines the electrical characteristics of dual power automatic transfer switch.

SWQ series double power automatic transfer switch is widely used, such as elevators, mines, banks, and hospitals can power outage occasions generally have double power automatic transfer switch, because once power outage, will cause huge economic losses, and even threaten the safety of people's lives.
