The On-Line Detection for AC Contactor’s Vibration Noise

Abstract:

In order to make the AC contactor’s working noise measured under enviroment with strong backgroud noise, a kind of noise detecting system is developed based on LabVIEW. Firstly,a vibrating signal is obtained by acceleration transducer;Then a noise value is figured out by using sound radiation efficiency index curve and A weighting curve. The results indicate that the measuring precision is 2dB. The noise detecting system meets the precision demand of noise detecting.
