Research on Spring Defect Detection System of High-Voltage Circuit Breaker in Power System

In view of the problems existing in the current real-time monitoring system of the tension spring pressure of the tension spring operating mechanism of the circuit breaker, a real-time monitoring system of the tension spring pressure of the tension spring operating mechanism is proposed. It uses an electronic push rod equipped with a hydraulic elastic device to press the hydraulic valve. When the electronic push rod moves to a certain position, the hydraulic elastic device will generate pressure, thereby releasing the stored spring energy. The hydraulic device can be activated by the accumulator motor to store energy when the power pole is restarted. By adjusting the switching value, the switching value reaches the maximum value.
