Problems solved by technology

[0005] The purpose of the present invention is to provide a post insulator assembly to solve the technical problem in the prior art that the guide block tends to be skewed when the central conductor expands with heat and contracts with cold, which reduces the grounding reliability of the post insulator; it also provides a GIL to solve In the prior art, when the central conductor expands with heat and contracts with cold, the guide block tends to be skewed, which reduces the grounding reliability of the post insulator and thus leads to the technical problem that the GIL is prone to discharge.

Abstract

The invention relates to the technical field of gas-insulated metal-enclosed transmission lines, in particular to a GIL and a post insulator assembly thereof. The post insulator assembly comprises a post insulator provided with a plurality of posts. One end of each post adjacent to the post insulator axis is fixed to each other, and the other end of each post is provided with an insert for connecting a particle trap. Each insert is provided with a guide block mounting seat provided with a guide block for supporting the casing inner wall of the GIL in the direction perpendicular to the post insulator axis in the guide mode, each guide block is provided with a grounding electrode disposed in the direction of the post insulator axis in the guide mode, one side of each guide block facing the corresponding insert is provided with more than two guide block support springs, and the side of each grounding electrode facing the corresponding insert is provided with an electrode spring. The guideblock support springs are arranged along the axial direction of the corresponding post insulator or in the circumferential direction around the axis of the corresponding post insulator.

Description

technical field [0001] The invention relates to the technical field of gas-insulated metal-enclosed transmission lines, in particular to a GIL and a post insulator assembly thereof. Background technique [0002] Gas-insulated metal-enclosed transmission line (GIL) is a new type of transmission line that adopts gas insulation and the shell is arranged coaxially with the center conductor. The center conductor is supported and installed in the shell by a post insulator. The pillars arranged in sequence in the circumferential direction of the axis, the radially outer ends of the pillars are provided with inserts, and the inserts are provided with grounding blocks to achieve equipotential conduction between the inserts and the shell (that is, grounding), and the inserts are grounded Effectiveness is directly related to the normal operation of the transmission system. According to the current statistical data, the phenomenon of discharge will occur during the operation of GIL. Th...
