Abstract:

This paper conducts off-line testing and statistical analysis of the characteristic parameters of a batch of contactors with a service life of about 15 years,including contact resistance,contactor pick-up noise,pull-in and release time,open and close coil inductance and resistance parameters.According to the test results,the correlation analysis between the parameters is carried out,which provides a data basis for the comprehensive evaluation of the contactor’s health status,the failure analysis of the contactor and the life prediction.

Key words: contactor, characteristic parameter, relevance, release time
