Problems solved by technology

There is a clear correspondence between the wiring sequence U, V, W outputted by the compressor driver and the compressor terminals R, S, T. The wiring sequences of compressors from different manufacturers are different. Wrong reverse connection will cause the current of the compressor to increase, and the current will fluctuate

Abstract

The invention provides a method and device for identifying reverse wiring of a compressor, the compressor and an air conditioner. The method for identifying reverse wiring of the compressor includes the steps of acquiring a fluctuation value of quadrature axis current of the compressor; and if the fluctuation value is greater than a preset fluctuation threshold, identifying reverse wiring of the compressor. According to the method and device for identifying reverse wiring of the compressor, the compressor and the air conditioner, whether the compressor is reversely wired or not can be identified by the fluctuation value of the quadrature axis current of the compressor, compressor damage caused by reverse wiring of the compressor is avoided, and the cost does not need to be increased.

Description

technical field [0001] The invention relates to the technical field of control, in particular to a method and device for identifying reverse connection of a compressor, a compressor and an air conditioner. Background technique [0002] With the popularization of frequency conversion household appliances in the market, frequency conversion compressors have also been expanded and applied on a large scale. There is a clear correspondence between the wiring sequence U, V, W outputted by the compressor driver and the compressor terminals R, S, T. The wiring sequences of compressors from different manufacturers are different. Wrong reverse connection will cause the current of the compressor to increase, and the current will fluctuate periodically. If it runs for a long time, the compressor will be damaged. [0003] In related technologies, sensors or other hardware devices are usually used to identify the reverse connection of the compressor wiring to prevent damage to the compre...
