Abstract

A panel is provided with a shaft hole, the shaft hole and a mandrel are concentrically arranged, the panel is further provided with a long hole, a shifting button is located in the long hole, the upper end of a cover plate is provided with a mounting groove, the upper end of the cover plate is fixedly connected to the lower end of the panel, a supporting plate is arranged in the mounting groove, the upper end of the supporting plate is fixedly connected to the lower end of the shifting button, and the upper end of the supporting plate is fixedly connected to the lower end of the shifting button. A receding hole is formed in the cover plate, the lower end of the supporting plate is fixedly connected to the upper end of the screw, the lower end of the screw is fixedly connected to the upper end of the sliding plate, the shifting button can sequentially drive the supporting plate and the sliding plate to slide, and the sliding sliding plate is of an opening and closing structure for locking the relative position of the mandrel. According to the padlock structure of the dual-power-supply change-over switch, the safety of a manual operator is guaranteed, the padlock piece can be lifted and locked only in a double-open state, the handle cannot be installed after locking, safety accidents caused by misoperation of the operator are avoided, the structure is simple, and operation is easy.

Description

technical field [0001] The invention belongs to the field of electrical switches, and in particular relates to a padlock structure of a dual power supply conversion switch. Background technique [0002] The automatic transfer switch appliance is a widely used terminal appliance. It mainly uses the controller on it to drive the electric operating mechanism to control the action of the switch, so as to connect or break the common and standby power supply, so as to ensure the safety and production of the power system. continuity. The transfer switch generally has three execution states: normal power switch on, backup power switch on and double-open. In the double-open state, the transfer switch device cuts off two power supplies at the same time to deal with equipment maintenance or other situations that require disconnection of the power supply. In this state, it is necessary to use the padlock device of the transfer switch to lock the transfer switch in the double-point stat...
