Abstract

Abstract:

The pull-in process is closely related to the response time and the reliability of the AC contactor.Firstly,an AC contact experimental system which can adjust the contact gap is introduced,and the waveforms of the contact voltage,moving iron core displacement and coil current are recorded in real time.Furthermore,the influence of the contact gap on the pull-in time,bounce duration,and stability duration is studied.Finally,the pull-in characteristics of AC contactor with the different contact gaps are discussed.

Key words: AC contactor, pick-up time, bounce time, pull-in characteristics
