Embodiment Construction
[0037] In order to make the object, technical solution and advantages of the present invention clearer, the method and system for testing air-conditioning electrical components according to the embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0038] The method for testing the air-conditioning electric device of the embodiment of the present invention, such as figure 1 shown, including the following steps:
[0039] S100. Test the waveform of the power supply in each preset area and the relative voltage harmonic content of the harmonics of each order of the power supply, obtain the power data of the preset area, and store it.
[0040] Because the power supply actually used by air conditioner users is very complex and usually contains more harmonic components, especial...

The invention discloses a method and a system for testing an air conditioner electric device. The method includes testing the power supply waveform of each preset area and the relative voltage harmonic content of each order harmonic of the power supply, obtaining the power data of the preset area, and storing it; according to the stored preset area different combinations of the harmonic content of each order in the power data and the fundamental wave of the power supply, and use the combination that has the greatest impact on the preset performance of the air-conditioning electrical device to be tested as the standard waveform of the actual power supply ; Using the standard waveform of the actual power supply to test the air-conditioning electrical components, and obtain the test results of the preset performance of the air-conditioning electrical components. The standard waveform of the actual power supply is used to test the electrical components of the air conditioner, so that the performance of the product can meet the needs of actual use, and the product can guarantee normal operation under the most damaging external conditions. Avoids the problem of malfunctioning of a product that has already been tested in a different environment.
Description
technical field [0001] The invention relates to the field of air-conditioning and refrigeration, in particular to a method and system for testing air-conditioning electrical components. Background technique [0002] At present, the performance test of air-conditioning electrical components in the industry is powered by mains power or regulated power supply, and then by adjusting different input voltages (usually 0.85-1.1 times the rated voltage), test whether the performance of air-conditioning electrical components meets the conditions, so as to judge Check whether the electrical components of the air conditioner are qualified. However, the actual power supply used by air conditioner users is very complicated. In this case, even if the performance test of air-conditioning electrical components is qualified according to the existing standards, the phenomenon of unstable performance will still occur in actual use. Contents of the invention [0003] In order to solve the p...
