Abstract
The utility model discloses a high-voltage high-strength lightning arrester porcelain sleeve, which comprises a porcelain body (4) and flanges (1), wherein a valve sheet hole (5) is arranged in the porcelain body (4), the external of the porcelain body (4) is provided with large umbrella skirts and small umbrella skirts which are arranged in a spaced manner, adhesive layers (3) are arranged between two ends of the porcelain body (4) and the flanges (1), the diameter of the large umbrella skirts ranges from 273 to 280mm, the diameter of the small umbrella skirts ranges from 243 to 250mm, the flanges (1) are made of high-strength cast aluminium alloy, the middle of the flanges (1) is provided with a guide rod fixing hole (8), and the flanges (1) are symmetrically provided with lugs (6). The high-voltage high-strength lightning arrester porcelain sleeve can ensure that the flanges are high in mechanical strength, reduces the weight of the flanges, and is convenient for fixing an insulating support of the lead and the lightning arrester; the flanges and the porcelain body are connected into a whole after being injected and solidified by adhesive made of sulfur, graphite and porcelain sand as raw materials, the solidifying time of the adhesive layer is shortened, the porcelain sleeve production efficiency is improved, the compactness of the adhesive layer is increased, the internal water pressure strength, thermal stability and operation reliability of the porcelain body are improved, and the export technical requirements of the porcelain sleeve is satisfied.
Description
Technical field
The utility model relates to a kind of insulator, especially relates to high pressure high strength arrestor porcelain bushing.
Background technology
High-voltage arrester is the of paramount importance protective device of high-tension power transmission and transformation equipment, and the quality of lightning arrester product quality is most important to the safe operation of electrical network.In electric power system, there is very important status.And high-voltage arrester insulator is one of key determining high-voltage arrester performance, insulator, as one of significant components of equipment, plays the insulation as lead-in wire, and has anchor leg and the effect of support over the ground in product.The arrestor porcelain bushing of current domestic use is mostly connected to form overall insulator by castiron flange high to porcelain piece and magnesium iron equal strength by pouring with being cement, but this to water with cement the insulator one forming be that cement cementing layer is grown curing time, the insulator production cycle is longer; The 2nd, in cement pouring process, easily produce bubble, cause cementing layer compactness to decline, interior hydraulic pressure intensity is lower, and thermal stability and operational reliability are not high; The 3rd, due to flange arrangement restriction, the insulating supporting and the lightning arrester that are not easy to lead-in wire are fixed, and can not meet exported product technology.
Utility model content
For the existing problem of insulator in above-mentioned prior art, the utility model provides not only cementing layer quick solidifying, insulator is with short production cycle, and insulator mechanical strength is high, thermal stability and operational reliability strong, can meet the high pressure high strength arrestor porcelain bushing of exported product technical requirement.
The technical scheme of clothes that the technical problems to be solved in the utility model is adopted is: the high-strength arrestor porcelain bushing of described high pressure comprises porcelain body and flange, in described porcelain body, be provided with valve block hole, porcelain body outside has spaced large full skirt and little full skirt, between described porcelain body two ends and flange, be provided with cementing layer, in the middle of described flange, there is guide rod fixing hole, described large full skirt diameter is 273-280mm, umbellule skirt diameter is 243-250mm, described flange adopts cast aluminium alloy to make, and is symmetrically arranged with ear platform on described flange.
Cementing layer is that using main is curing the forming of adhesive pouring that material component is made by sulphur, graphite and porcelain sand.
For destroying cementing layer in anti-sealing and moisture infiltration cementing layer, be provided with at flange port (flange small end and the porcelain body place of matching) sealant made from waterproof silicon rubber.
The utility model technical indicator:
1, brown glaze on surface,
2, bending resistance failing load: 15KN.M is above, tensile failing load: 145KN is above, Compressive failure load: more than 200KN,
3, interior hydraulic pressure proof pressure: more than 2.3KPa.
The utlity model has Multiple Type: MCA0, MCA1, MCA2, MCA3, MCA4, MBA0, MBA1, MBA2, MBA3, MBA4, MEA0, MEA1, MEA2, MEA3, MEA4.
The utility model one is to adopt the flange that has Er Tai and replace existing hot galvanizing spheroidal graphite cast-iron to make with the flange that high strength cast aluminium alloy is made, can not only guarantee that flange has high mechanical strength, and having alleviated flange weight, insulating supporting and the lightning arrester of being convenient to lead-in wire are fixed; The 2nd, the curing insulator entirety that connects into of adhesive pouring that flange and porcelain body adopt sulphur, graphite and porcelain sand material component to make, not only shorten cementing layer curing time, improve the production efficiency of insulator, and improve the compactness of cementing layer, the interior hydraulic pressure intensity and thermal stability and the operational reliability that have improved porcelain piece, meet the requirement of insulator export techniques.
