The conductive knife of the isolating switch, the gear box and the gear box body of the conductive knife

Abstract

The invention relates to a conductive disconnecting link of a disconnecting switch, a gear box of the conductive disconnecting link and a gear box body. The conductive disconnecting link of the disconnecting switch comprises an upper conductive tube, a lower conductive tube and a gear box which is connected with the upper conductive tube and the lower conductive tube; the gear box comprises a gearbox body; a gear shaft for assembling a gear is arranged in the gear box body by means of bearing transmission; a rack matched with the gear is arranged in the gear box body; the gear box body comprises a box body unit; end cover mounting holes which are used for exposing the meshing portions of the gear and located in at least one side of the gear shaft are formed in the box body unit; the end cover mounting holes are provided with end covers; and the corresponding ends of the gear shaft are rotationally arranged on the end coves. According to the gear box body, the box body unit and the endcovers are installed in a matched manner; the end cover mounting holes can expose the meshing portions of the gear; and when the end covers are arranged on the box body unit, the meshing conditions of the gear and the rack can be observed through the end cover mounting holes, and therefore, the meshing accuracy of the gear and the rack can be ensured.

Description

technical field [0001] The invention relates to a conductive switch knife of an isolating switch, a gear box of the conductive knife knife and a box body of the gear box. Background technique [0002] The high-voltage isolating switch is a switching device mainly used for line switching under no-current-carrying conditions, and for electrically isolating high-voltage busbars, circuit breakers and other equipment and high-voltage lines to be overhauled. It can provide a Meet the requirements of the insulating environment. [0003] The application publication number is CN106504933A, and the Chinese patent application with the publication date of 2017.03.15 discloses a large-capacity high-voltage DC isolating switch. The structure of the high-voltage DC isolating switch is as follows: Figure 1 to Figure 2 As shown, the conductive switch knife 15 is included, the conductive switch knife 15 includes an upper conductive tube 16 and a lower conductive tube 17, a gear box 18 is ins...
