  • Dual energy storage operating mechanism of isolating switch
    Patent number: 11756755
    Abstract: A dual energy storage operating mechanism of an isolating switch is provided. A first energy storage mechanism and a second energy storage mechanism are provided between an input wheel and a housing and between the input wheel and an output wheel or a first output shaft, respectively. The output wheel is provided with a limiting mechanism. The limiting mechanism forms a locking effect on the output wheel when the first energy storage mechanism stores energy, thereby enabling the second energy storage mechanism to store energy at the same time. When the first energy storage mechanism starts to release energy, the locking effect of the limiting mechanism is released, so that the output wheel and the first output shaft can rotate, and the first energy storage mechanism and the second energy storage mechanism release energy at the same time, forming a dual energy storage boosting effect.
