High-voltage fuse insulation sleeve for gas insulation switch cabinet

Abstract

The invention relates to high-voltage insulation equipment of an electric power system, in particular to a high-voltage fuse insulation sleeve for a gas insulation switch cabinet. The insulation sleeve comprises an insulator, a sealing head, a high-voltage fuse head end connecting piece, a high-voltage fuse tail end connecting piece, a head wiring end and a tail wiring end, wherein a high-voltage fuse containing cavity extends from the bottom of the insulator in the axial direction, and the high-voltage fuse head end connecting piece is arranged at the inner side end of the high-voltage fuse containing cavity; the outer side end of the high-voltage fuse accommodating cavity is provided with a high-voltage fuse tail end connecting piece, and the high-voltage fuse tail end connecting piece is plugged in the high-voltage fuse accommodating cavity through a sealing head; the first wiring terminal and the tail wiring terminal are arranged on the outer side of the insulator, the first wiring terminal is connected with a first-end connecting piece of the high-voltage fuse, and the tail wiring terminal is connected with a tail-end connecting piece of the high-voltage fuse. The device is reliable in insulation, uniform in electric field, reasonable in structure, flexible in installation, good in sealing performance and convenient to replace the fuse, and the design of the sulfur hexafluoride gas insulation switch cabinet is perfected.

Description

technical field [0001] The invention relates to high-voltage insulation equipment in a power system, in particular to a high-voltage fuse insulation sleeve for a gas-insulated switchgear. Background technique [0002] The high voltage fuse insulation sleeve is the main insulating part on the sulfur hexafluoride gas insulated switchgear, and it is the insulation guarantee between the high voltage fuse and the switch cabinet. The quality of the high voltage fuse insulation will directly affect the sulfur hexafluoride gas insulated switchgear The performance and reliability of equipment and personal safety. At present, the high-voltage fuses in the sulfur hexafluoride gas-insulated high-voltage switchgear are not protected by insulating sleeves, so that the insulating medium is completely dependent on sulfur hexafluoride gas, which increases the installation space of the high-voltage fuses and makes the installation inflexible. If the high-voltage fuse is damaged and needs to ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems of large installation space, inflexible installation and inconvenient replacement of existing high-voltage fuses used in sulfur hexafluoride gas-insulated switchgears, the invention provides an insulating sleeve for high-voltage fuses used in gas-insulated switchgears
