Double-path automatic switching cabinet power supply distribution unit

Abstract

The invention relates to a double-path automatic switching cabinet power supply distribution unit. The double-path automatic switching cabinet power supply distribution unit comprises a rear shell anda panel, wherein the rear shell is provided with an A-path power incoming line and a B-path power incoming line, and a power output socket and a lamplight indicating board are arranged on the panel;a circuit board, a J1 alternating-current contactor and a J2 alternating-current contactor are further arranged in the rear shell; the circuit board comprises a J3 indicating control relay, a J4 switching control relay, an A-path power supply sampling module, a B-path power supply sampling module, an output power supply sampling module, a level inverter IC and a J5 relay. By means of the double-path automatic switching cabinet power supply distribution unit, continuous power supply of the industrial cabinet power supply distribution unit is achieved, double-power-supply switching circuits andcontrol devices which are usually complex and high in cost are saved, the flexibility and reliability of double-path power supply switching control and output are improved, and the power supply powerconsumption of a double-power-supply switching control circuit can be greatly reduced.

Description

technical field [0001] The invention relates to the field of dual-channel power switching control, in particular to a dual-channel automatic switching cabinet power distribution unit. Background technique [0002] The power distribution device is an industrial multi-channel power output socket, which is widely used in the fields of electric power, telecommunications, transportation, chemical industry and finance. It can be installed in the power distribution cabinet of the and other equipment to provide working power; the dual power supply automatic switcher is a device that ensures that the electrical equipment cannot be powered off. Power supply, when the main power supply loses power, the backup power supply automatically switches the power supply, and when the main power supply resumes, it automatically returns to the main power supply state; if the dual power switcher and power distributor are combined to form a power distribution device, It can bring great convenience...

[0002] The power distribution device is an industrial multi-channel power output socket, which is widely used in the fields of electric power, telecommunications, transportation, chemical industry and finance. It can be installed in the power distribution cabinet of the and other equipment to provide working power; the dual power supply automatic switcher is a device that ensures that the electrical equipment cannot be powered off. Power supply, when the main power supply loses power, the backup power supply will automatically switch the power supply, and when the main power supply resumes, it will automatically return to the main power supply state; if the dual power switcher and power distributor are combined to form a power distribution device, It can bring great convenience to the user; although the switching speed of the dual power switching device using pure electronic control on the market is relatively fast, the price is relatively expensive, and the switching speed of the dual power switching device using electromechanical control is very slow. Need to add manual assistance, and the volume is relatively large
