Problems solved by technology

[0009] However, Korean Patent Publication No. 10-2010-0083257 only discloses a solution to the problem that the movable scroll may reverse when the torque of the rotating shaft formed is smaller than the pressure of the compressed gas, but for the compression The patent publication does not provide a solution to the problem of electromechanical motors rotating in reverse due to momentary power failure

Abstract

The present disclosure provides a compressor fault diagnosis device, method and system, and compressor equipment. The compressor failure diagnosis device includes: a current sensing unit to sense a current flowing through a motor of the compressor; a failure diagnosis unit to determine whether the motor performs reverse rotation based on the current flowing through the motor; and a cutoff unit , to remove the power supply based on the determination result of the fault diagnosis unit. The present disclosure can control the operation of the compressor, thereby improving the operation reliability of the compressor.

Description

[0001] Cross-reference related application [0002] The present application claims priority to Korean applications from January 11, 2019, all of which are incorporated herein by reference. Technical field [0003] The present disclosure relates to a compressor fault diagnostic apparatus and a system and a diagnostic method thereof, and a compressor device, and the diagnostic apparatus and the diagnostic method can determine whether the compressor rotates in reverse rotation due to instantaneous power failure. Background technique [0004] In general, the compressor is a device that converts a compression energy that can be converted into a compressible fluid, and can be used as part of a refrigeration device (eg, a refrigerator or air conditioner). [0005] The compressor is mainly divided into reciprocating compressors, rotary compressors, and scroll compressors. In the reciprocating compressor, the compression space for inhaling or discharging the working gas is formed to compre...
