Abstract

The contact making process significantly influences the electrical response time and electrical contact resistance of power electromechanical relays (EMR). This paper presents the electrical contact behaviors of bridge-type contacts in power EMR at low velocity conditions by introducing our self-designed test rig. The fundamental phenomena in the contact resistance and contact force were investigated under velocity of 2 mm/s. Effects of parallelism deviation, environment temperature and current load on electrical contact resistance were investigated and interpreted explicitly. Furthermore, a mathematical model which is relative to the variation of response time in making process is built. Finally, the influence mechanisms of the elevated temperature environment on the reduction in the electrical response time and the increase in the contact force are discussed.
