Problems solved by technology

However, the upper conductive tube in this conductive connection device is fixedly connected with the end cap; in order to ensure product quality and assembly effect, the upper conductive tube must be filled with fillers, which not only increases the number of parts in the product, but also increases the assembly work. It increases the trouble, and because there are many conductive connection links, the heating parts are increased, which will affect the stability of the performance of the device and reduce the service life

Abstract

The invention relates to an electric connecting device for an outdoor high-voltage isolating switch, which comprises a lower conducting tube and an upper conducting tube, wherein the lower conducting tube is fixedly connected with a shaft seat; a shaft sleeve is positioned outside the shaft seat; an insulating bracket is arranged inside the shaft sleeve; the insulating bracket is provided with a through hole; the inside of the through hole is provided with an insulating bushing and a spring and corresponds to a ball contact finger; the ball contact finger and a bearing are positioned between the inner wall of the shaft sleeve and the outer wall of the shaft seat; one end, far away from the shaft sleeve, of the lower conducting tube is provided with an end cover; a conductor and the shaft sleeve are fixed into a whole; the conductor is arranged in the upper conducting tube; and the conductor and the upper conducting tube are fixedly connected through a bolt. The electric connecting device for the outdoor high-voltage isolating switch is not easy to corrode, has few conducting connection links and more compact structure, reduces heating parts, makes the performance of the device more stable, and has better conducting function and motion transmission functional effects.

Description

Technical field: [0001] The invention relates to a conductive device on power distribution equipment, in particular to a conductive device for an outdoor high-voltage AC isolating switch. Background technique [0002] The main function of the high-voltage AC isolating switch in the power system is to pass the rated current for a long time when the switch is closed, and to increase the obvious and visible isolation fracture for the line when the switch is opened, which is convenient for maintenance and protection. According to the characteristics of the movement of the product, there are folding type, horizontal rotation type and vertical opening type isolating switches in the structure selection. Their main movement feature is that the movement of the conductive base drives the action of the conductive tube during opening and closing, so that the conductive tube is in the position of In the opening or closing position, the folding isolating switch, through the folding action...
