An insulating rod assembly and a solid-sealed pole

Abstract

The invention discloses an insulating pull rod component and a solid-sealed polar pole. The insulating pull rod component comprises an insulator component, an insulating pull rod and a sealing mechanism, wherein the insulating pull rod is fixedly connected with the insulator component; the insulator component is connected with a vacuum pipe of the solid-sealed polar pole; the insulating pull rod is connected with an operating mechanism; the sealing mechanism comprises a sliding bushing which sleeves the insulating pull rod and a sealing film of which one end is connected with the sliding bushing and the other end is hermetically connected with a shell of the solid-sealed polar pole. The solid-sealed polar pole comprises a shell, a vacuum arc extinguishing chamber and an insulating pull rod chamber; the vacuum arc extinguishing chamber is positioned in the shell and is provided with the vacuum pipe; the insulating pull rod chamber is provided with the insulating pull rod component. The insulating pull rod component and the solid-sealed polar pole belong to the technical field of high-voltage switch gears, the technical problems that the sealing member is easy to damage and meanwhile the movement of the insulating pull rod is affected since the sealing member of the existing insulating pull rod with the sealing member is directly and fixedly connected to the insulating pull rod are solved, the polar pole can be prevented from being polluted, the sealing member is difficult to damage, and the influence on the movement of the insulating pull rod by the sealing member is reduced.

Description

technical field [0001] The invention belongs to the technical field of high-voltage switchgear, and in particular relates to an insulating pull rod assembly and a solid-sealed pole. Background technique [0002] At present, the vacuum interrupter, also known as the vacuum switch tube, is the core component of the medium and high voltage power switch. Its main function is to quickly extinguish the arc and suppress the current after the medium and high voltage circuit is cut off through the excellent insulation of the vacuum inside the tube, so as to avoid Accidents and accidents happen. Generally, the insulating shell of the vacuum interrupter is exposed to the air, and there is a problem of being polluted by external dust and moisture. In order to reduce this effect, the outer shell of the vacuum interrupter is required to have sufficient length, which not only affects the miniaturization of the vacuum interrupter, but also affects the performance and reliability of the vac...

AI Technical Summary

Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention lies in the existing insulating tie rods with sealing members, whose sealing members are directly affixed to the insulating tie rods, causing the sealing members to be easily damaged, and the movement of the insulating tie rods will also be significantly affected by the sealing members , so as to provide an insulating rod assembly and a solid-sealed pole that can prevent the pole from being polluted while its sealing member is not easily damaged, and the movement of the insulating rod is less affected by the sealing member
