Abstract

The invention relates to a resin fiber insulating spacer for SF6 high-voltage switchgear and a manufacturing method thereof. A disc-shaped insulating main body is formed by laminating fiber cloth and pouring epoxy resin to be condensed into an integrated structure, the fiber-reinforced strength is far higher than that of an epoxy resin aluminum oxide insulating spacer subjected to vacuum pouring, the mechanical property is better, and the insulating spacer is not prone to damage, so that under the same mechanical property requirement, the resin fiber insulating spacer for the SF6 high-voltage switchgear can be thinner than a traditional insulating spacer, the weight of the insulating spacer is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to a resin fiber insulating basin used for SF6 high-voltage switchgear and a manufacturing method thereof. Background technique [0002] Basin insulator is an important insulating part of high-voltage switchgear, which mainly plays the role of insulation, support and isolation of gas chamber. [0003] Traditional basin insulators are formed by vacuum casting with epoxy resin added with alumina filler. Since the thickness of epoxy resin is relatively thick, generally more than 40mm, it is prone to cracking. And the density of the casting is about 2.2-2.4g / cm3, and the weight is relatively heavy. The conductor (aluminum insert) in the middle of the pot insulator is pre-embedded and then poured, which is easy to form stress concentration between the resin and the insert, which affects the hydraulic strength of the pot insulator. Contents of the invention [0004] In view of the above-mentioned shortcoming of the prior art, the ob...
