An isolating/grounding switch with integrated arrangement and its operating mechanism and transmission structure

Abstract

The invention relates to the field of GIS devices, and in particular to an integratedly arranged isolating / earthing switch and an operation mechanism and transmission structure thereof. The integratedly arranged isolating / earthing switch includes an operation mechanism which includes a transmission structure and a drive apparatus. The transmission structure includes a worm and gear decelerator which has an input shaft and 2 output shafts. The input shaft and output shafts separately extend from 3 lateral sides of the worm and gear decelerator. The 2 output shafts are in respective transmission connection to an on / off indicator and an auxiliary switch. The on / off indicator and the auxiliary switch are arranged on the worm and gear decelerator, specifically on the lateral side which is parallel to the axes of the output shafts. According to the invention, the worm and gear decelerator of one core transmission mechanism is adopted to replace transmission structures that are scattered at each part of a machine frame of an original operation mechanism, the on / off indicator and the auxiliary switch are arranged in the periphery of the worm and gear decelerator, and integrate arrangement of the transmission mechanism is achieved and the volume of the entire apparatus is reduced.

Description

technical field [0001] The invention relates to the field of GIS equipment, in particular to an integrated isolation / grounding switch, an operating mechanism and a transmission structure thereof. Background technique [0002] At present, the transmission structure of the operating mechanism of the isolation / grounding switch generally adopts a screw nut plus a grooved plate transmission, a gear plus a grooved wheel transmission, or a chain plus a special-shaped gear transmission, etc., and the various parts of the operating mechanism are fixed on a frame. Then use the above-mentioned transmission method to drive and connect the various parts, and finally set an integral casing outside the entire operating mechanism to cover the entire operating mechanism in general. [0003] Because there are many parts in the entire operating mechanism, the frame of the operating mechanism is huge, and the transmission parts of the operating mechanism are scattered in various positions of th...

AI Technical Summary

Problems solved by technology

[0003] Because there are many parts in the entire operating mechanism, the frame of the operating mechanism is huge, and the transmission parts of the operating mechanism are scattered in various positions of the frame, resulting in scattered structure of the entire operating mechanism, which is not compact enough. In the end, the entire mechanism is bulky; and in the assembly process of the operating mechanism, because the number of parts is large and the transmission components are too scattered, the entire production assembly is also very difficult; Inside the shell, all transmission equipment is exposed to the air, without separate and more detailed protection, resulting in a high failure rate of the operating mechanism, mainly manifested in motor burnout, brake failure, and opening and closing release failure. etc., threatening the safe operation of the power grid
