Dual-power change-over switch and operating system thereof

Abstract

The invention discloses a dual power supply change-over switch and an operation system thereof, and relates to the field of power supply conversion, the dual power supply change-over switch comprises a support base, and further comprises a plurality of groups of conduction assemblies which are arranged on the support base and are used for providing input ends of a plurality of groups of power supplies; the switch-on assembly is arranged on the supporting base, the power box assembly is arranged on the supporting base, the power output end of the power box assembly is arranged on the switch-on assembly, and the arc extinguishing assembly is arranged in the power box assembly. According to the invention, power is concentrated by using the power box assembly, so that the two input ends on the conduction assembly are switched by using the power box assembly, and the arc generated in the switching process can be fully absorbed by using the arc extinction assembly, so that the arc in the power switching process can be eliminated, and the power supply switching efficiency is improved. And meanwhile, the situation that multiple groups of power supplies are not unified enough and delay exists during switching due to arc conduction in the switching process of the multiple groups of power supplies can be avoided.

Description

Technical field [0001] The present invention relates to a field of power conversion, specifically a dual power conversion switch and an operating system thereof. Background [0002] Dual power supply automatic toggle switch refers to: a microprocessor controlled, used in the grid system network electricity and network power or network power and generator power to start the switching device, can make the power supply continuous source power supply. Among them, in the process of dual power conversion, the corresponding arc will be generated according to the corresponding voltage, especially when the conversion is carried out at the same time for multiple sets of power transfer switches, there will be a difference in the conversion time in the process of conversion, or due to the existence of arcs, the time of conduction between multiple sets of power transfer switches due to the existence of arcs is not necessarily certain, so that the uniformity of the use of multiple sets of pow...
