Description

technical field [0001] The invention relates to a three-position compound isolating and grounding switch, in particular to an isolating switch and a grounding switch for gas-insulated fully enclosed combined electrical appliances, belonging to the field of high-voltage power transmission. Background technique [0002] The three-position isolating and grounding switch is often used in fully enclosed combined electrical appliances (GIS) or composite electrical appliances (PASS), and is not a separate product. At present, there are two main transmission structures of the three-position isolating and grounding switch seen at home and abroad: One is the crank arm structure, the connecting mechanism of the operating mechanism drives the seal shaft and the transmission shaft to rotate, and the opening or closing operation of the isolating switch and the grounding switch in the three-position isolating and grounding switch is completed through the output angle of the crank arm; the o...
