Embodiment Construction

[0022] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] An embodiment of the retractable isolating switch in the present invention is as Figure 1~Figure 4 As shown, it is a vertical opening and closing telescopic isolating switch, including a moving end assembly 10 and a static end assembly 20 .

[0024] The moving end assembly 10 includes a cylinder mounting plate 11 and a cylinder 12 fixed on the cylinder mounting plate 11. The cylinder 12 includes a cylinder body 121 and a two-stage piston that is arranged on the cylinder body 121 for guiding movement. The first-stage piston 122 on the cylinder body 121 and the second-stage piston 123 arranged on the first-stage piston 122 are guided to move, and the two-stage piston can expand and contract step by step during use. Wherein the top of the secondary piston 123 is coaxially fixed with a moving contact 15 and a moving contact pressure equalizing cover...

Abstract

The invention relates to a telescopic isolation switch and a moving-end assembly thereof. The telescopic isolation switch comprises the moving-end assembly and a static-end assembly, wherein the moving-end assembly comprises a cylinder and a piston arranged on the cylinder in a guided movement mode, reinforcement rods parallel to the axis of the piston are fixed on the piston, and the reinforcement rods are arranged on the cylinder in a guided movement mode along the direction parallel to the axis of the piston. By use of such a technical scheme, due to arrangement of the reinforcement rods, the piston and the reinforcement rods can form a frame structure, the stability of the piston is enabled to be greatly improved, the frictional force applied to the piston itself can be reduced, wear is reduced, it is ensured that the movement locus of a moving contact is accurate, deviation is avoided, the structure is compact, arrangement of other components is not affected, the cost is low, and the realization is easy.

Description

technical field [0001] The invention relates to a retractable isolating switch and its moving end assembly. Background technique [0002] The vertical opening and closing telescopic isolating switch has been widely used in places such as power transmission and power testing. Existing retractable isolating switches, such as a pneumatic high-voltage isolating switch disclosed in a Chinese patent with the authorized announcement number CN 203631391 U, include a static end assembly and a moving end assembly, the static end assembly includes a static contact, and the moving end assembly includes a telescopic cylinder , the telescopic cylinder is an air cylinder, and the piston rod of the air cylinder guides and moves and is arranged on the cylinder body to form a section of piston. There is a limit joint on the top of the cylinder, a lower flange on the bottom, a bus bar on the outside, a moving contact on the top of the piston, and a limit ring on the outside. The bus bar and t...
