Abstract

The invention relates to a buckling and tripping device for automatic transfer switching equipment. The buckling and tripping device comprises a base plate, wherein a buckling mechanism and a tripping mechanism. The buckling mechanism comprises a lever plate body and a buckling plate, wherein the lever plate body and the buckling plate are hinged to the base plate, the buckling plate is located at one end of the lever plate body, a roller capable of rolling on the buckling plate and being embedded into a buckling groove formed in the buckling plate is arranged in the lever plate body and the lever plate body rotates on the base plate to enable the roller to be embedded into the buckling groove so as to achieve switching-on control of an automatic transfer switch. The tripping mechanism comprises a connecting plate installed on the buckling plate and a tripping action mechanism, wherein the tripping action mechanism enables the roller to break away from the buckling groove in the buckling plate through the connecting plate so as to achieve switching-off control of the automatic transfer switch. The buckling and tripping device is simple and compact in structure and capable of achieving remote operation on the automatic transfer switch, improving the on-off performance of the automatic transfer switching equipment and ensuring the switching-on and switching-off reliability of the automatic transfer switch.

Description

Technical field

[0001] The invention relates to a lock and trip device, in particular to a lock and trip device of an automatic transfer switch electrical appliance, in particular to a lock and trip device used to ensure the reliable opening and closing of the automatic transfer switch electrical appliance, belonging to The technical field of low-voltage switchgear. Background technique

[0002] In low-voltage power distribution systems, automatic transfer switching appliances have become an indispensable and important part for monitoring power circuits. In the event of a power failure, one or several load circuits can be automatically converted from the failed power supply to the backup power supply to ensure uninterrupted power supply for important loads. The simpler the operation structure of the automatic transfer switching device, the higher the reliability of the automatic transfer switching device. The locking device of the operating mechanism must be able to ensure the ...
