Abstract

The utility model discloses a kind of compound inslation poles, including vacuum interrupter, static side cover board and moved end cover board are respectively equipped at the both ends of vacuum interrupter, ceramic insulating layer is equipped on the surface of vacuum interrupter, layer of silica gel is coated on the outside of the ceramic insulating layer, epoxy resin is coated on the outside of the layer of silica gel, wherein ceramic insulating layer and the contact interface of layer of silica gel are 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 utility model 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 increasing 30% or so originally 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

A kind of compound inslation pole
Technical field
The utility model relates to a kind of electrical equipments, especially compound inslation pole.
Background technique
Vacuum circuit breaker is changed to pole structure by open type, insulation in recent years, and the breaker assembled with it has Small in size, light-weight, the service life is long, and high reliablity is easy to maintain, pollution-free, uses safe advantage.
Pole, that is, solid-sealing vacuum arc-chutes carries out vacuum interrupter and upper and lower outlet whole with epoxy resin Casting, 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 can generate huge convergent force, and the ceramic layer that will lead to vacuum interrupter is 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.
Utility model content
A kind of compound inslation sealing pole is provided purpose of the utility model is to solve above-mentioned the deficiencies in the prior art Column.
To achieve the goals above, compound inslation pole designed by the utility model, including vacuum interrupter, The both ends of vacuum interrupter are respectively equipped with static side cover board and moved end cover board, are 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, epoxy resin is coated on the outside of the layer of silica gel, wherein ceramic insulation Layer and the contact interface of layer of silica gel are 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, comprising the following steps: layer of silica gel raw material is subjected to mixing, and will The sulfurizing mould of layer of silica gel is preheated, and layer of silica gel is then made after vulcanizing, 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 after waiting preheating in vacuum Arc chamber surface spraying binder, 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 pressure maintaining of epoxy resin is finally carried out, is opened up to compound inslation pole.
The compound inslation pole that the utility model obtains, vacuum interrupter pass through encapsulated pretreatment, vacuum interrupter The buffering effect of layer of silica gel be improved, and there is no bubble, the exterior insulation that can significantly improve vacuum interrupter is horizontal, simultaneously It is adopted in ceramic insulating layer and the contact surface of layer of silica gel using annular ripple face and in the contact interface of layer of silica gel and epoxy resin With annular ripple face, so that the linear distance between the static side cover board and moved end cover board of vacuum interrupter becomes curve, therefore two Insulation distance between person than originally increases 30% or so, has changed simultaneously the interface state for improving two kinds of materials, has 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.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the compound inslation pole of embodiment 1.
In figure: vacuum interrupter 1, static side cover board 2, moved end cover board 3, ceramic insulating layer 4, layer of silica gel 5, epoxy resin 6.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Embodiment 1:
As shown in Figure 1, compound inslation pole provided in this embodiment, including vacuum interrupter 1, in vacuum interrupter 1 both ends are respectively equipped with static side cover board 2 and moved end cover board 3, are equipped with ceramic insulating layer 4, the pottery on the surface of vacuum interrupter 1 The outside of porcelain insulating layer 4 is coated with layer of silica gel 5, and the outside of the layer of silica gel 5 is coated with epoxy resin 6, wherein ceramic insulating layer 4 It is annular ripple face with the contact interface of layer of silica gel 5, the contact interface of layer of silica gel 5 and epoxy resin 6 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, comprising the following steps: 5 raw material of layer of silica gel is subjected to mixing, and The sulfurizing mould of layer of silica gel 5 is preheated, layer of silica gel 5 is then made after vulcanizing, then uses the surface of vacuum interrupter 1 Alcohol or acetone clean up, and then the vacuum interrupter 1 cleaned is put into baking oven and is preheated, and wait after preheating true Empty 1 surface spraying binder of arc-chutes, reuses pipe expander and expands layer of silica gel 5, the vacuum interrupter 1 sprayed is packed into In layer of silica gel 5, the die-filling material feeding pressure maintaining of epoxy resin 6 is finally carried out, is opened up to compound inslation pole.
