Novel double-earthing high-voltage isolation switch

The utility model provides a novel double-earthing high-voltage isolation switch. The novel double-earthing high-voltage isolation switch comprises a high-voltage isolation switch operating mechanism case, operating connecting rods and a double-earthing isolation switch body, wherein the high-voltage isolation switch operating mechanism case is provided with three output shafts; the three output shafts include a main isolator output shaft, a left earthing isolator output shaft and a right earthing isolator output shaft; the main isolator output shaft is connected with a first connecting shaft of the high-voltage isolation switch body by the first operating connecting rod; the first connecting shaft is connected with a main isolator; the left earthing isolator output shaft is connected with a second connecting shaft of the high-voltage isolation switch body by the second operating connecting rod; the second connecting shaft is connected with a left earthing isolator; the right earthing isolator output shaft is connected with a third connecting shaft of the high-voltage isolation switch body by a third operating connecting rod; the third connecting shaft is connected with a right earthing isolator. The novel double-earthing high-voltage isolation switch has high work reliability, is simple to operate, is low in investment cost and is convenient to install and maintain in the field.
