Description

(1) Technical field [0001] The invention belongs to the field of electric switch equipment, and relates to an automatic transfer switch electric appliance. (2) Background technology [0002] In the prior art, the automatic transfer switch is divided into two types according to the structure: the combined automatic transfer switch assembled by two circuit breakers, which has a large volume and slow conversion speed; the other type is specially designed for power switching. The integrated automatic transfer switching electrical appliance is characterized by small size, fast switching speed, reliable operation and high performance indicators. The one-piece structure only has products below 400A in the current market. The existing opening and closing mechanism has complex structure, low reversing accuracy and poor reliability. [0003] For example, the patent number is CN200420042705.1, and the patent name is a Chinese utility model patent for dual-power automatic transfer swi...
