Abstract

The utility model relates to a capacitance composite jacket tube, which is a piece of insulating apparatus suitable for the situation when a high-voltage conductor passes through a transformer casing or the wall of a substation, and is composed of a supporting frame, an insulating layer and metal support members. The supporting frame is sheathed and fixed with the insulating layer, and the external surface of the insulating layer is fixed with the metal support members. The utility model has the advantages of small size, light weight, good antifouling property and little occurrence of explosion. The utility model can effectively prevents the occurrence of pollution flashover accidents, and ensures the safe operation of power system.

Description

A kind of condenser type synthesizes sleeve pipe

The utility model relates to a kind of seal when being used for high-pressure conductor and passing transformer case or electric substation's wall.

In recent years, along with the quickening of power grid construction and the expansion of supertension line, reliability requirement to system is more and more higher, the anti-pollution measure in heavily contaminated area is constantly being strengthened, and the synthetic sleeve pipe that uses in China's electric power system at present is the electroceramics goods, and pollution flashover takes place easily, and also can cause explosion accident when overheated, this device self is wrecked, and the porcelain fragment that produces is with the safety of the entail dangers to person and other electric equipment.Needing to drop into great amount of manpower and material resources and financial resources in running goes to safeguard and clean.

The purpose of this utility model is exactly the synthetic sleeve pipe of condenser type that provides at above-mentioned deficiency that a kind of volume is little, in light weight, explosion-proof performance is good, setting angle is unrestricted, can prevent the generation of pollution flashover accident effectively.

The technical solution of the utility model is: the synthetic sleeve pipe of condenser type is made up of support frame, insulating barrier and metallic supports; The intrinsic insulating barrier of cover is fixed with metallic supports on the insulating barrier outer surface on support frame.

Support frame in the technique scheme can be to penetrate metal conducting bar or the lead of being made by copper or aluminium in core, also can cancel sandwich layer and directly use metal conducting bar, is about to metal conducting bar as support frame.

Insulating barrier in the technique scheme is divided into three layers, internal layer is an insulator, middle one deck is a semiconductor loop, outermost layer is made up of full skirt, it is by high temperature vulcanized the forming of high molecular polymer that is matrix with silicon rubber, closely is bonded in the semiconductor outer surface with special binding agent, three layers of insulating barrier, every bed boundary all uses special binding agent closely to bond together, and makes its no gap.

The utility model is compared with traditional porcelain bushing and is had the following advantages:

1, volume is little, in light weight, and setting angle is unrestricted;

2, have excellent antifouling property, can prevent the generation of pollution flashover accident effectively;

3, in service being difficult for blasts, and avoids the accident extension;

4, the production size is accurate, and the margin of tolerance is little;

5, can improve the electric field strength distribution of earth terminal effectively.

Accompanying drawing is the structure chart of the synthetic sleeve pipe of condenser type.

Further specify the utility model below in conjunction with accompanying drawing:

The utility model is made of support frame, insulating barrier and metallic supports 5, sandwich layer 6 usefulness epoxy tubes or metal tube are made, it is the support frame of sleeve pipe, penetrate therebetween outside the conducting rod 1 and extraction tube of copper or aluminum, also can cancel the sandwich layer 6 of hollow, directly use metal conducting bar 1, be about to metal conducting bar 1 as support frame; Insulating barrier is by insulator 4, semiconductor loop 2 and full skirt 3 constitute, sandwich layer 6 outer surfaces evenly are coated with the special bonding agent of last layer after treatment, the high molecular polymer insulator 4 that will be matrix with silicon rubber is fixed in sandwich layer 6 outer surfaces, then semiconductor loop 2 is fixed in insulator 4 outer surfaces, half storey body ring 2 is made up of a kind of semi-conducting material, this semi-conducting material direct-to-ground capacitance is bigger, be mainly used in and improve metallic supports earth terminal electric field strength, it is comparatively even that voltage is distributed, the special binding agent of full skirt 3 usefulness closely is fixed in semiconductor loop 2 outer surfaces, does not have air gap therebetween; Metallic supports 5 is fixed on the outer surface of middle part insulator 4 of synthetic sleeve pipe, the support of metallic supports 5 during in order to ground connection.
