Problems solved by technology

The DC compressor generates a large starting current at the moment of starting. If there is no protection measure, the excessive starting current will easily burn some components in the circuit; and due to the limited space of the bus, the components involved in the protection circuit cannot occupy too much space. , and considering the need for easy disassembly and assembly for subsequent maintenance, it is necessary to develop a device that is easy to install and disassemble, and has a good inhibitory effect on the starting current of the DC compressor

Abstract

The invention relates to a protection circuit assembly for starting a direct-current compressor. A base and an upper shell of the protection circuit assembly are fixedly connected to form a first accommodating space; a main circuit, a pre-charging circuit and a discharging circuit are arranged in the first accommodating space; the main circuit is used for providing a working power supply for the direct-current compressor; the pre-charging circuit is used for providing reactive compensation when the direct-current compressor is started so as to reduce the starting current; the discharging circuit is used for discharging after the direct-current compressor is shut down; a four-position wire connector is installed on the base, the four-position wire connector penetrates through the upper shell, the main circuit, the pre-charging circuit and the discharging circuit, and the direct-current compressor is electrically connected with a power supply through the four-position wire connector. Theupper shell is provided with a four-core wire holder, and the main circuit and the pre-charging circuit are in signal connection with an external control circuit through the four-core wire holder. The starting efficiency of the direct-current compressor can be improved, the service life of the direct-current compressor can be prolonged, and the direct-current compressor is small in size, simple in structure, convenient to assemble and disassemble and high in applicability.

Description

technical field [0001] The invention relates to the field of protection circuits, in particular to a protection circuit assembly for starting a DC compressor. Background technique [0002] With the vigorous promotion of electric passenger cars, DC compressors have also been widely used in electric passenger car air conditioners. The DC compressor generates a large starting current at the moment of starting. If there is no protection measure, the excessive starting current will easily burn some components in the circuit; and due to the limited space of the bus, the components involved in the protection circuit cannot occupy too much space. , and considering the need for easy disassembly and assembly for subsequent maintenance, it is necessary to develop a device that is easy to install and disassemble, and has a good inhibitory effect on the starting current of the DC compressor. Contents of the invention [0003] Aiming at the technical problems existing in the prior art,...
