Problems solved by technology

[0004] However, during the above switching process, the movable contact and the fixed contact may be inseparable (for example, the movable contact and the fixed contact are welded). After the above problem occurs, the drive shaft will still rotate to the disconnected position , that is, the operating handle may still stay in the OFF position, which cannot indicate the failure of the switching device

Abstract

The invention discloses a resetting assembly of a switch cabinet. The resetting assembly comprises a resetting spring (14), a resetting sliding block (16) and a linkage piece (26), wherein the resetting spring can be fixed on a cabinet door of the switch cabinet; the resetting sliding block is connected with a resetting spring; the linkage piece is fixed on a connection shaft of the switch cabinet and can rotate along with the connection shaft of the switch cabinet; with the closing of the cabinet door of the switch cabinet, the linkage piece can push the resetting sliding block to move towards the direction of compressing the resetting spring, and due to the release of the resetting spring, the resetting sliding block can be driven to push the linkage piece to rotate. According to the resetting assembly disclosed by the invention, mis-operation after a switching device is faulted can be effectively prevented.

Description

technical field [0001] The present invention relates to a reset assembly, in particular to a reset assembly capable of judging whether a switching device is faulty, and also relates to a switchgear with the above reset assembly. Background technique [0002] In the switching device, by operating the drive shaft to switch between the open position and the closed position, the contact and separation of the movable contact and the fixed contact can be realized, thereby realizing the on-off control of the power supply line. In order to realize the rapid completion of the contact and separation between the movable contact and the fixed contact in the switchgear, an elastic mechanism is usually provided, which mainly uses the spring to store or release the elastic potential energy to drive the completion of the contact and separation between the movable contact and the fixed contact. . At the same time, the large torque generated by the spring in the switching action can be used ...
