Abstract
The utility model discloses a power sampling circuit device for an automatic transfer switch. The device comprises a power inlet end, a controller and a power sampling wire connecting the power inlet end and the controller, and is characterized in that a middle node for electrically isolating the power inlet end and the controller is arranged on the power sampling wire. Compared with the prior art, the connection line design of switching on and switching off the middle node can totally make up shortcomings of the traditional connection line. The switching on and switching off of the middle node can quickly realize the switching on and the switching off between the inlet end of the electric switch device and the controller. If the power supply sampling needs to be stopped, the middle node only needs to be switched off; and if the power supply sampling needs to be recovered, the middle node only needs to be switched on. The disconnection and the recovered connection can be carried out quickly and conveniently, and problems of wrong connection and missed connection can be effectively avoided.
