Electrical Life Prediction and Research on Test of AC Contactor
AC contactor with the rated current of 12A is to be the research object in this paper.The simulation module of electromagnetic mechanism of AC contactor with dynamic characteristic calculation and analysis is designed by experiment and simulation research, so the best and worst closing phase angle is determined, and the foundation of speeding up electrical life experiment is laid.The phase angle selection device is made and the control program based on the software of LabVIEW is programmed, as a result, it has the function of automated acquisition, data classification of the waveform, alarm and so on.The test method of electrical life with fixed angle is adopted, the electrical life experiment and data acquisition of 120,000 times is accomplished by life test system.The data processing module is established, which can read the characteristic parameters about electrical life, so the efficiency of life test is improved.By analyzing the trend of arcing time, no-load make duration of contact with the increasing of electrical life times, the prediction model of electrical life of AC contactor is established according to the prediction method of time-series.
