Description

The glass core disk of plate-shaped suspension type Glass Composite Insulator

Technical field

The utility model is related to insulator technology fields, more particularly to the antifouling work ability that can improve insulator and resistance to Dirty performance, can be maintained after aging degree of umbrella skirt the reliable hanging net operation of insulator a kind of plate-shaped suspension type Glass Composite Insulator glass Core disk.

Background technology

Insulator is indispensable important component in high voltage power transmission and transforming circuit, traditional glass insulator is antifouling, The method in glass insulator surface spraying PRTV anti-pollution flashover coatings is usually taken to improve its antifouling work in anti-sudden strain of a muscle energy force difference Can, but the coating price is expensive, and need a large amount of human and material resources and time, and prolonged power-off often brings and can not estimate Loss, the time of holding is also relatively short, and that there are product interior insulation intensity is low for traditional porcelain insulator, easy breakdown appearance " zero " value And lose insulating effect, surface creepage apart from small, hydrophobicity performance is poor, easily by acid rain, dust pollution, clean and maintenance are costly, pass The shortcomings of easy embrittlement of compound rod type insulator of uniting is exploded, after there is problem of aging in silicon rubber umbrella skirt, the plug of interior insulator Brittle failure easy to aging.

Invention content

Glass core disk anti-fouling flashover performance that the utility model solves existing Glass Composite Insulator is poor, anti-pollution characteristic is low Technical problem, and a kind of antifouling work ability that can improve insulator and anti-pollution characteristic are provided, insulation can be maintained after aging degree of umbrella skirt A kind of glass core disk of plate-shaped suspension type Glass Composite Insulator of sub reliable hanging net operation.

Technical solution used by the utility model is：

A kind of glass core disk of plate-shaped suspension type Glass Composite Insulator, the glass of the plate-shaped suspension type Glass Composite Insulator Glass core disk includes core disk ontology, and the core disk ontology is cup-shaped, and the medial surface and lateral surface of the core disk ontology are spiral shell Line structure；The edge of the core disk ontology is provided with extension obliquely, and the extension is arranged to recessed and its end There is first protrusion of circle；The upper surface of the extension is provided with second protrusion of circle, and the described second protrusion is close to described Core disk ontology setting.

Core disk ontology, extension, the first protrusion and second protrusion is integrally formed.

The beneficial effects of the utility model are：

1. core disk ontology is cup-shaped, medial surface and lateral surface are helicitic texture, the medial surface of core disk ontology and insulation The steel feet of son is connected by cement adhesive, and the lateral surface of core disk ontology is connected with the chapeau de fer of insulator by cement adhesive It connects, it is more smooth since core disk is glass core disk, helicitic texture is made in its medial surface and lateral surface, it can be with cement adhesive Preferable bond stress is formed, to reach and steel feet and chapeau de fer are good is fixedly connected with effect, cup-shaped core disk ontology, in silicon After problem of aging occurs in rubber full skirt, the reliable hanging net operation of insulator can be also maintained；

2. the edge of core disk ontology is provided with extension obliquely, extension has a circle first convex to recessed and its end It rises, the creepage distance of insulator can be increased, improve the antifouling work ability of insulator；

3. the upper surface of extension has second protrusion of circle, the second protrusion that can increase climbing for insulator close to core disk ontology Electrical distance improves the antifouling work ability of insulator；

4. core disk ontology, extension, the first protrusion and the second protrusion are integrally formed, it is ensured that insulator has good Anti-pollution characteristic.

In short, the glass core disk of plate-shaped suspension type Glass Composite Insulator provided by the utility model, which has, can improve insulator Antifouling work ability and anti-pollution characteristic, the advantages of insulator reliable hanging net operation can be maintained after aging degree of umbrella skirt.

Description of the drawings

Fig. 1 is a kind of structural schematic diagram of the glass core disk of plate-shaped suspension type Glass Composite Insulator described in the utility model （Sectional view）.

In figure：1, core disk ontology；2, extension；3, the first protrusion；4, the second protrusion.

Specific implementation mode

The utility model is described in further detail in the following with reference to the drawings and specific embodiments.

As shown in Figure 1, a kind of glass core disk of plate-shaped suspension type Glass Composite Insulator, including core disk ontology 1, core disk ontology 1 is cup-shaped, and the medial surface and lateral surface of core disk ontology 1 are helicitic texture, the edge of core disk ontology 1 obliquely integrally formed with Extension 2, to recessed and its end integrally formed with first protrusion 3 of circle, the upper surface of extension 2 is integrally formed extension 2 There are second protrusion of circle 4, the second protrusion 4 to be located at close to the position of core disk ontology 1.

When specifically used, the medial surface of core disk ontology 1 is connected with the steel feet of insulator by cement adhesive, core disk The lateral surface of ontology 1 is connected with the chapeau de fer of insulator by cement adhesive, the screw thread of core disk ontology 1 medial surface and lateral surface Structure can be with cement gluing dosage form at good bond stress, to securely fix the steel feet and chapeau de fer of insulator, because of core Disk ontology 1 is cup-shaped, after problem of aging occurs in the silicon rubber umbrella skirt of insulator, can also maintain the reliable hanging net operation of insulator, The creepage distance that insulator can be increased with 2 integrally formed first protrusion 3 of extension and the second protrusion 4, improves the anti-of insulator Pollution flashover ability.
