Abstract

The invention provides a manual-automatic and padlock structure of a dual-power change-over switch. The structure comprises a shell, a deflector rod assembly, a first baffle plate, a second baffle plate and a microswitch, the deflector rod assembly, the first baffle plate, the second baffle plate and the microswitch are arranged in the shell, a mounting hole is formed in the middle of the shell, the deflector rod assembly is connected in the mounting hole, the shell is a groove structure, the first baffle plate, the second baffle plate and the microswitch are all installed in the groove structure of the shell, and the microswitch is in signal connection with a controller of the change-over switch. According to the manual-automatic and padlock structure of the dual-power change-over switch, a signal is given out during manual operation, an electric operation circuit of the controller is disconnected, electric operation is avoided during manual operation, the interlocking effect is achieved, the safety of manual operation personnel is guaranteed, a padlock piece can be lifted and locked only in a double-open state, and a handle cannot be mounted after locking so that safety accidents caused by misoperation of personnel are avoided, the structural design is reasonable and simple, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to a manual, automatic and padlock structure of a dual power supply 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...
