Assessing the Ageing Condition and Lifetime of Electromagnetic Relay in Nuclear Power Plant

Abstract:

Article Preview

The Ageing mechanisms of electromagnetic relay were discussed. And the key ageing indicators were found out. Then, the test methods of ageing indicators were introduced. After that, a method to evaluate the lifetime for the coil of electromagnetic relay was proposed. Accelerated ageing test was conducted to the coils, and the key ageing indicators were collected periodically. According to those test data, the ageing condition and lifetime were evaluated. In the end of the paper, examples about assessing the ageing condition and lifetime were given separately.
