Mechanical And Electrical Life Requirements Of Electromagnetic Current Relay
Nov 16, 2017

Mechanical and electrical life requirements of electromagnetic current relay

1, mechanical life should be not less than 5000 times.

2, electrical life: when rated load, should not be less than 1000 times.

3, the mechanical life test, the relay applied 2 times the value of the value of electricity, so that the action, 0.7 times the value of the value of electricity to make it return, the contact without load (but should be allowed to carry less than 5W signal load).

4, the reliability life test in mechanical and electrical life test process, each movable system relay shall be reliable action and return, each contact can reliably connected and disconnected (no stable arc and the static contact phenomenon between the contacts, or stick) relay in mechanical and electrical life test, should ensure that the reliability of its work.

5, the speed of electric life test should be considered without harmful heat accumulation or ion accumulation on the contact point, so it should be carried out at least 1 times of /s.

6, after life test, the relay mechanical performance should be good, the error allowed to increase the value by product technical conditions, insulation pressure value allowed to drop to the specified value of 75%.
