Abstract:The failure of the operating spring stress in high-voltage circuit breakers, along with fatigue fracture, can result in inadequate opening and closing speeds, exceeding the specified opening and closing times, and the inability to close, seriously affecting the safe and stable operation of equipment and the power grid. In the actual production and maintenance processes, neglecting the operating conditions of the high-voltage circuit breaker spring, such as temperature, loading position, preload, motor vibratio… Show more
