Abstract
The invention discloses a kind of compound inslation poles, including vacuum interrupter, it is respectively equipped with static side cover board and moved end cover board at the both ends of vacuum interrupter, it is equipped with ceramic insulating layer on the surface of vacuum interrupter, it is coated with layer of silica gel on the outside of the ceramic insulating layer, it is coated with epoxy resin on the outside of the layer of silica gel, the wherein contact interface of ceramic insulating layer and layer of silica gel is annular ripple face, and the contact interface of layer of silica gel and epoxy resin is also annular ripple face.The compound inslation pole that the present invention obtains, the buffering effect of the layer of silica gel of vacuum interrupter is improved, and there is no bubble, the exterior insulation that vacuum interrupter can be significantly improved is horizontal, annular ripple face makes the distance between static side cover board and moved end cover board of vacuum interrupter than originally increase 30% or so simultaneously, the interface state for improving two kinds of materials has been changed simultaneously, surface dielectric structure is changed, has avoided straight line breakdown.
Description
Technical field
The present invention relates to a kind of electrical equipments, especially compound inslation pole.
Background technology
Vacuum circuit breaker is changed to pole structure by open type, insulation in recent years, and the breaker assembled with it has
Small, light-weight, long lifespan, reliability is high, advantage easy to maintain, pollution-free, safe to use.
Pole, that is, solid-sealing vacuum arc-chutes carries out vacuum interrupter and upper and lower outlet whole with epoxy resin
Cast, is encapsulated into a single piece, is a much progress of vacuum circuit-breaker insulated technology.
Currently, pole is all made of the production of injecting type pressure gelation process, epoxy resin is with colloidal state quilt under high temperature
It is injected into pole die cavity, after heat preservation after a period of time, epoxy resin can gradually cool down, this cooled
Journey will produce huge convergent force, and the ceramic layer of vacuum interrupter can be caused broken.And since epoxy resin and ceramics belong to
Two kinds of materials, therefore can have a factors such as gap in contact interface, and these are for the insulation breakdown of pole that there are larger hidden
Suffer from.
Invention content
It provides the purpose of the present invention is to solve above-mentioned the deficiencies in the prior art and a kind of improving insulation compressive resistance
Compound inslation pole and its production method.
To achieve the goals above, the compound inslation pole designed by the present invention, including vacuum interrupter, in vacuum
The both ends of arc-chutes are respectively equipped with static side cover board and moved end cover board, and ceramic insulating layer is equipped on the surface of vacuum interrupter, described
Be coated with layer of silica gel on the outside of ceramic insulating layer, be coated with epoxy resin on the outside of the layer of silica gel, wherein ceramic insulating layer with
The contact interface of layer of silica gel is annular ripple face, and the contact interface of layer of silica gel and epoxy resin is also annular ripple face.
The distance between the peaks and troughs in the annular ripple face are 3-4mm, and the distance between two wave crests are 10-
12mm。
A kind of production method of compound inslation pole, includes the following steps：Layer of silica gel raw material is subjected to batch mixing, and will
The sulfurizing mould of layer of silica gel is preheated, and layer of silica gel is then made after vulcanization, then by the surface alcohol of vacuum interrupter
Or acetone cleans up, and then the vacuum interrupter cleaned is put into baking oven and is preheated, and goes out in vacuum after waiting preheating
Arc chamber surface spraying adhesive, reuses pipe expander and expands layer of silica gel, and the vacuum interrupter sprayed is packed into layer of silica gel
In, the die-filling material feeding pressurize of epoxy resin is finally carried out, is molded up to compound inslation pole.
The compound inslation pole that the present invention obtains, vacuum interrupter pass through encapsulated pretreatment, the silicon of vacuum interrupter
The buffering effect of glue-line is improved, and does not have bubble, and the exterior insulation that can significantly improve vacuum interrupter is horizontal, while making pottery
Porcelain insulating layer and the contact surface of layer of silica gel use ring using annular ripple face and in the contact interface of layer of silica gel and epoxy resin
Shape corrugated surface so that the air line distance between the static side cover board and moved end cover board of vacuum interrupter becomes curve, therefore the two it
Between insulation distance than originally increase 30% or so, changed simultaneously the interface state for improving two kinds of materials, changed surface
Dielectric structure avoids straight line breakdown, in this way design so that the service life of product is elongated, and insulating properties improves.
