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...

Abstract

The invention discloses a method and a system for testing air-conditioning electric devices. The method comprises testing a power supply waveform of each preset region and relative voltage harmonic content of each order harmonic wave of the power supply, obtaining power data of the preset region, and storing the power data; according to the stored power data of the preset region, performing various combinations on the content of each order harmonic wave in the power data and a fundamental wave in the power supply, using a combination which has the greatest impact on preset performance of a to-be-tested air-conditioning electric device as a standard waveform of an actual power supply; using the standard waveform of the actual power supply to test the air-conditioning electric device, to obtain a test result of preset performance of the air-conditioning electric device. The method uses the standard waveform of the actual power supply to test the air-conditioning electric device, so that each item of performance of a product satisfies actual use requirement, and the product is ensured to normally operate under a maximum damaging external condition. A problem that a product which has passed the test has operation faults in different environments.

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...
