Title:
COMPRESSOR PROTECTION CIRCUIT, METHOD, AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/211128
Kind Code:
A1
Abstract:
A compressor protection circuit, comprising: a voltage divider circuit (10), provided with a temperature control switch and used for outputting a voltage signal in response to an action of the temperature control switch, the temperature control switch acting on the basis of the temperature of a cylinder of the compressor; a signal processing circuit (30), connected to the voltage divider circuit (10) and used for outputting a control signal on the basis of a comparison result of a reference voltage signal, namely the voltage signal output by the voltage divider circuit (10), and a comparison voltage signal; and a power device (50), connected to the signal processing circuit (30) and used for controlling the working state of the compressor on the basis of the control signal. The invention solves the technical problem of low reliability of an existing compressor overheat protection scheme. Also disclosed is a compressor protection method and apparatus.
