Abstract

The digitized constant current control system was designed according to the problems of small DC electromagnetic relay's contact test current, long test time, service life difficult to predict etc. This equipment can fulfill constant stress, step stress and sequence to stress accelerated life test of DC electromagnetic relay by adjust the current. The measure and control software based on Labview, realized test current continuous controlled, pressure drop of contact closed and disconnected automatic measurement, failure of automatic identification, action frequency controllable regulation, data automatic storage. Through the practical application, equipment has the characteristics of test accuracy, reliable work, etc. This equipment offer fast and effective test condition for accurately predicting DC electromagnetic relay's service life.
