Evaluation on the Long-Term Operational Reliability of Closing Springs in High-Voltage Circuit Breakers

Evaluation on the Long-Term Operational Reliability of Closing Springs in High-Voltage Circuit Breakers

As a key energy storage component in high-voltage circuit breakers, closing springs are susceptible to stress relaxation, resulting in a decline in closing performance due to high operational loads, prolonged usage, and environmental factors. In this work, the 60Si2CrVA alloy steel springs used in 1...
