Harm Analysis of Spring Defects in Circuit Breaker Mechanical Failure

With the continuous development of the power system, the importance of circuit breakers has gradually emerged, becoming a key link to ensure the normal operation of the power system. However, circuit breaker mechanical failure defects often occur in the power system, such as plum blossom contact defects, split closing coil defects, tentacle defects, etc., which inhibits the normal operation of the power system and also increases the operation and maintenance costs of power companies. Based on this, this paper takes the Taiyuan Power Grid as an example to study the harm of spring defects in circuit breaker machinery, aiming to find out an effective method to eliminate the spring defects in order to achieve the purpose of contributing to the normal operation of the power grid.
