Problems solved by technology

[0002] At present, there are difficulties in the detection of air conditioner compressors. When the air conditioner installed in the user's room fails, because the compressor failure is difficult to detect, maintenance personnel often replace the compressor directly without careful inspection and analysis, resulting in sometimes good compressors. directly replaced, resulting in waste
Since there is currently no dedicated compressor testing equipment, maintenance personnel usually need to carry resistance measuring instruments, current / voltage value measuring instruments, oscilloscopes and other equipment, which is very inconvenient, and the existing testing methods require the air conditioner Detect compressor input test signal

Abstract

The invention provides an air conditioner compressor fault detection tool. The air conditioner compressor fault detection tool is characterized in that the fault detection tool comprises a detection module, which is connected to an air conditioner compressor, comprises a current / voltage value detection module, a current / voltage waveform detection module and a resistance value detection module, andis used for obtaining detection data; a master control module, which is connected to the detection module and is used for carrying out compressor fault diagnosis with the design data of an air conditioner and a compressor as well as the detection data being combined, and outputting the detection data and the diagnosis result; and a data input / output module, which is connected to the master control module and is used for reading the design data of the air conditioner and the compressor, and outputting the detection data and the diagnosis result. The air conditioner compressor fault detection tool integrates functions of compressor motor winding resistance measurement, current / voltage detection and current / voltage waveform detection, and can detect electrical parameters when the compressoroperates, thereby realizing live-line detection.

Description

technical field [0001] The invention relates to the technical field of air conditioner compressor fault detection, in particular to a fault detection tool and a fault detection method for an air conditioner compressor. Background technique [0002] At present, there are difficulties in the detection of air conditioner compressors. When the air conditioner installed in the user's room fails, because the compressor failure is difficult to detect, maintenance personnel often replace the compressor directly without careful inspection and analysis, resulting in sometimes good compressors. It is directly replaced, causing waste. Since there is currently no dedicated compressor testing equipment, maintenance personnel usually need to carry resistance measuring instruments, current / voltage value measuring instruments, oscilloscopes and other equipment, which is very inconvenient, and the existing testing methods require the air conditioner Check the compressor input test signal. ...
