Abstract

The invention relates to the field of high-voltage switch cabinets, in particular to a ring latch device for electrical five preventions. The ring latch device for the electrical five preventions comprises a clamping piece, a lock body, and a lock fork, a lever section, a driving assembly and a control unit which are arranged in the lock body; the control unit controls the driving assembly to work; the driving assembly drives the connection end of the lever section to move up and down; when the connection end of the lever section moves upwards, the device can be locked reliably and firmly due to mutually close cooperation of the lever section, the locking fork and the clamping piece; when the connection end of the lever section moves downwards, the buckling end moves upwards and releases the buckling fork end of the locking fork, the bearing end of the clamping piece is not fixed and limited by the driving fork end of the locking fork, and a clamping part can be separated from the free end of a hook section to realize unlocking; and the whole process of locking and unlocking is convenient and reliable, and the ring latch device is high in safety.

Description

technical field [0001] The invention relates to the field of high-voltage switch cabinets, in particular to an electrical five-proof padlock device. Background technique [0002] At present, in industrial production, the five electrical defenses refer to: preventing mis-disconnection and mis-closing of circuit breakers, load switches, and contactors; preventing disconnecting and closing isolating switches with load; preventing mis-closing of grounding switches when electrified; In the closed position, close the circuit breaker and load switch; prevent entering the charged room by mistake. The electrical five-proof requires that the high-voltage switch cabinet cannot open the cabinet door when the high-voltage is live, and the high-voltage switch cabinet must be equipped with a locking device. [0003] In order to meet the above requirements, the existing conventional design is to install a common padlock device on the cabinet door, for example, such as figure 1 As shown, i...
