Abstract

The dynamic contact resistances of HH52P electromagnetic relays are measured under different ambient air temperature. Their diagnostic parameters are extracted and determined. It is found that the ambient air temperature obviously influences some parameters. In order to research its influence on the electrical contact reliability of electromagnetic relay, the statistic analysis is applied to study the static contact resistance, the max of the dynamic contact resistance and the bounce time. It is found that the ambient air temperature regularly influences the three parameters. Thoroughly, the phenomenon is studied and analyzed in the point of material science so as to probe into the essential matter of it.
