Improvement Design of the Trip Electromagnet in Spring Operating Mechanism
In order to solve the problems such as trip time instability
unreliable of the electromagnet with single iron core and double trip coils
the authors improve the structure of the electromagnet and the trip system through theoretical analysis and research
design the electromagnet with double iron cores and double trip coils. Then the improved electromagnet structure completely solves the above two problems by tests. The test results show that the improvement of the electromagnet has reached the expected effect.
