Abstract:
In order to improve the electrical durability of contactors in heavy duty condition,the failure factors such as product structure,contact pressure and contact resistance are confirmed by theoretical analysis of dynamic stability and thermal stability.It is proved that the above failure factors do have significant influence on the performance of contactor through short time capacity test and electric life test.
Key words: electrical life, heavy load, contact pressure, contact resistance, temperature rise, short-time withstand overload current
