Abstract

The invention relates to an automatic transfer switch with double power sources. The automatic transfer switch comprises a substrate, a base, a switching control device and breaker modules arranged on the two sides of the switching control device. The switching control device comprises two drive sliders and a switching mechanism. The switching mechanism comprises a motor and a switching piece fixedly arranged on a motor rotation shaft. The drive sliders and the substrate are in sliding fit. One ends, matched with the switching piece in a linkage mode, of the drive sliders are provided with an upper stop block and a lower stop block which are arranged on two layers. The switching piece comprises a lower first ejection block and an upper second ejection block which are arranged on an upper layer and a lower layer respectively. Through the first ejection block, the second ejection block, the upper stop block and the lower stop block, turning on and off of the breaker modules on the two sides are controlled respectively without interference when the switching piece rotates. When the first ejection block on one side makes contact with the lower stop block, the second ejection block on the other side makes contact with the upper stop block, and the effect that one breaker module is turned on and the other breaker module is turned off is achieved.

Description

technical field [0001] The invention relates to an automatic transfer switch electrical appliance, in particular to an automatic transfer switch with dual power supplies. Background technique [0002] At present, dual-power automatic transfer switch has been very common in daily life. The known dual-power automatic transfer switch is composed of two circuit breakers with accessories, a set of transmission mechanism controlled by the motor handle in two ways, and a controller. composition. When working, two circuit breakers switch between the normal and standby power sources, and ensure that only one circuit breaker is in the closed state to continuously supply power to important occasions. However, most of the transmission devices connected to the motor power transmission shaft in the common dual power automatic transfer switches on the market are gears or rocker devices, and their structures are too complicated, which brings inconvenience to production and processing.
