Problems solved by technology
[0002] The operating mechanism of the existing isolating switch is single-axis output. For the isolating switch with an attached grounding switch, an operating mechanism needs to be installed at the same time for each set of grounding switches, which may cause cumbersome on-site installation. The isolating switch and the grounding switch locking device are installed at the far end of the transmission system, with complex structure and poor reliability

Description
technical field [0001] The invention relates to an electric operating mechanism with dual output shafts of an AC high-voltage isolation switch. Background technique [0002] The existing isolation switch operating mechanisms are all single-axis output. For the isolation switches with grounding switches attached, one operating mechanism needs to be installed at the same time for each set of grounding switches attached, which may cause tedious on-site installation. The isolating switch and the grounding switch locking device are installed at the far end of the transmission system, with complex structure and poor reliability. SUMMARY OF THE INVENTION [0003] The invention relates to an electric operating mechanism with dual output shafts of an AC high-voltage isolating switch, which is not only simple in structure, but also simple in installation, high in control precision and reliable in locking. [0004] The present invention adopts the following technical solutions: an e...
