Switching circuit, system and method for control power of battery swap station, controller and medium

Abstract

The invention relates to a switching circuit, system and method for the control power of a battery swap station, a controller and a medium. The switching circuit comprises a first power supply circuitand a second power supply circuit, wherein the input end of the first power supply circuit is connected to a first transformer, and then is successively connected with a first circuit breaker, a second circuit breaker and a control power output end; the control power output end is used for outputting electric energy for powering each device of the battery swap station; the input end of the secondpower supply circuit is connected with a second transformer, and then is successively connected with an electromagnetic contactor and a switching output end; the switching output end is connected tothe control power output end; the normally open contact of the first circuit breaker is connected in series with the no-voltage release coil circuit of the second circuit breaker; and the normally closed contact of the first circuit breaker is connected in series with an electromagnetic contactor coil circuit. The switching circuit automatically, safely and reliably switches the control power of an electric vehicle battery swap station at low cost.

Description

technical field [0001] The invention relates to the technical field of electric vehicle swapping stations, in particular to a switching circuit, a system, a method, a controller and a medium for controlling a power supply of a swapping station. Background technique [0002] With the rapid development of the electric vehicle industry, more and more electric vehicle replacement stations have settled in cities. During the construction of the substation, in order to minimize investment and avoid repeated construction of transformers and lines, the self-built transformers will be given priority to provide power for the substation, because the built transformers usually have a surplus. However, the built-up transformer margin is generally not very large, and the margin of one transformer is generally not enough to meet the load requirements of the substation. Therefore, the power of the substation is usually taken from two different built transformers. After the two transformer l...

Problems solved by technology

[0004] (1) The main contact of the electromagnetic contactor of the double miniature circuit breaker double electromagnetic contactor switching method is always in the closed state, and most of the load is the inductive load of the motor. When running for a long time, the main contact of the electromagnetic contactor is easy Adhesion, and then burn out the electromagnetic contactor, easy to cause failure

[0005] (2) The ATS automatic transfer switch of the ATS automatic transfer switch method is bulky, difficult to install and arrange, and the price is high
