Problems solved by technology

The power system has always attached great importance to the safe operation of the system, but there will always be various accidents caused by electrical misoperation every year, causing unnecessary losses
In order to effectively prevent personal and major equipment accidents caused by misoperation of operating electrical equipment, padlock devices are provided on existing electric operating mechanisms for circuit breakers. However, the structural design of the padlock devices of existing electric operating mechanisms is complicated. The cost is high, and the reliability of the padlock device is low, and there are even potential safety hazards

Abstract

The invention relates to a padlock device of an electric operating mechanism, which comprises a mechanism frame, a shell and a padlock assembly arranged on the mechanism frame, the padlock assembly comprises a padlock piece arranged on the mechanism frame in a sliding mode, a spring arranged between the mechanism frame and the padlock piece, a first microswitch arranged on the mechanism frame and matched with the padlock piece, and a manual push block arranged on the mechanism frame in a sliding mode and capable of shielding the manual operation shaft. The second microswitch is arranged on the mechanism frame and matched with the manual push block, a padlock hole is formed in one end of the padlock piece, a lock piece hole allowing the padlock piece to penetrate through is formed in the shell, when the padlock hole is exposed out of the shell, one side of the padlock piece abuts against the manual push block, and the other side of the padlock piece abuts against the manual push block. And the limiting fit between the padlock sheet and the manual push block is formed. The device has the advantages of simple structure, stable and reliable performance, low cost, safety and reliability.

Description

technical field [0001] The invention relates to an electric operating mechanism, in particular to a padlock device of the electric operating mechanism. Background technique [0002] The electric operating mechanism is a special accessory for molded case circuit breakers. After matching with the circuit breaker, it can electrically close, open and re-close the circuit breaker remotely to realize the centralized and automatic control of the transmission and distribution network. The power system has always attached great importance to the safe operation of the system, but there will always be various accidents caused by electrical misoperation every year, causing unnecessary losses. In order to effectively prevent personal and major equipment accidents caused by misoperation of operating electrical equipment, padlock devices are provided on existing electric operating mechanisms for circuit breakers. However, the structural design of the padlock devices of existing electric op...
