Abstract :
Time parameters of electromagnetic relay used in aerospace such as the bound time, the arcing time, the over-travel time and the stability time can effectively describe the contact reliability. So these parameters should be carefully measured and checked before the relay is used. There are many devices which can test a series of time parameters at present time. But none of them can measure the stability time. To solve this problem, a method for measuring stability time of electromagnetic relay used in aerospace is proposed and the corresponding test equipment is designed in this paper. The test results indicate that the method has a high precision and reliability.
