Embodiment Construction
[0017] An embodiment of the direct connection structure of the operating mechanism of the switchgear of the present invention is as follows Figure 1~Figure 2 As shown, for 550kV isolating / earthing switch. The direct-connected structure includes an isolating switch, a grounding switch, a fast grounding switch, a corresponding operating mechanism and a direct-connected transmission device. The isolating switch, the grounding switch, and the fast grounding switch are respectively provided with corresponding input shafts; There are multiple sets corresponding to the input shafts one by one, and output shafts are provided; the corresponding input shafts and output shafts are respectively connected by corresponding direct transmission devices. Among them, the isolating switch and the grounding switch adopt pure electric operation structure, and the fast grounding switch adopts the electric spring operating mechanism.
[0018] The direct-coupled transmission device includes a tra...
