The primary purpose of circuit breaker mechanical characteristic testing is to evaluate the performance and operational status of the equipment, ensuring safe and reliable operation. These tests involve detailed measurement and analysis of critical parameters such as opening/closing time, speed, and travel distance. The aim is to identify potential issues, extend equipment lifespan, and enhance the stability and safety of power systems.

Through the comparison of test results and circuit breaker parameters, it can be concluded that all the circuit breaker results are qualified.
