The center of the casing tube is provided with a conductor, the outer part of the conductor is provided with a capacitance insulating layer, the outer part of the capacitance insulating layer is provided with a sheath, and the outer part of the sheath is fixed with an umbrella skirt. The utility model is characterized in that the capacitance insulating layer is divided into multiple sections in radial direction, and a barrier layer made of insulation material is arranged between two adjacent sections, and an outermost layer capacitance screen of each section is electrically connected with a first capacitance screen of a next section. The utility model has the advantages of small mass, favorable antifouling property, good stress performance and no occurrence of partial concentrative dislocation of the insulating layer.
Description
The utility model relates to a kind of bushing, particularly a kind of dry-type high-voltage sleeve pipe.
The various device outlet sleeve pipe of the above electric pressure of 35kV that tradition is used and transformer station mostly is capacitance type structure greatly with wall bushing oil-filled porcelain bushing, as shown in Figure 1, it is the insulating barrier 2 that is provided with capacitance type structure in a center conductor 1, the outside of this insulating barrier 2 is fixing with porcelain bushing 3, fills transformer oil between porcelain bushing 3 and insulating barrier.Though transformer oil can improve insulation property, bring also that quality is big, the shortcoming of easy to leak, explosive, inflammable, antifouling property difference.The insulating barrier that soaks the capacitance type structure of paper based on epoxy is also arranged, fills a kind of half dry type bushing of the pasty state insulating material of silicone grease class between porcelain tube and the insulating barrier, this half dry type bushing complex process, cost an arm and a leg and quality big.Thereby adopt again with polytetrafluoroethylene film and constitute capacitive dry-type high-voltage sleeve pipe as the main insulation material, as shown in Figure 2, as oversheath 5, the oversheath overcoat is silicon rubber full skirt 6 admittedly for porcelain bushing for the outside usefulness multiphase polymer radiation crosslinking heat-shrink tube of its condenser type insulating barrier 4.The sleeve pipe insulating material stressing conditions of this structure is poor.For the problem that solves the stressing conditions difference proposes a kind of structure as shown in Figure 3 again, Fig. 3 structure is at the comparatively weak a kind of improvement of its stressing conditions on Fig. 2 basis, its capacitance type structure 7 and material are identical with Fig. 2, and replace porcelain bushings with high-intensity resin pipe 8, the solid silicon rubber full skirt 9 of high-intensity resin pipe 8 overcoats, though filling macromolecular material 10 this structure stressing conditions between high-intensity resin pipe 8 and the capacitance type structure 7 improves to some extent, but equally with Fig. 2 have a following shortcoming: the coefficient of friction of polytetrafluoroethylmaterial material is very little, producing and in service because to hold the be stretched prestressing force that produced of polytetrafluoroethylene film in the process inhomogeneous and easily cause insulating barrier generation concentration of local to misplace (as shown in Figure 4), thereby cause this place's minor insulation to be easy to generate damage, possible generation systems accident.
The purpose of this utility model is to propose at the above-mentioned deficiency of prior art that a kind of quality is little, antifouling property good, the dry-type high-voltage sleeve pipe of insulating barrier concentration of local dislocation does not take place.
Above-mentioned purpose of the present utility model is realized by following technical scheme.
A kind of dry-type high-voltage sleeve pipe, its center has a conductor, and conductor is provided with the condenser type insulating barrier outward, and the condenser type insulating barrier is provided with sheath outward, the intrinsic full skirt of sheath overcoat; It is characterized in that: this condenser type insulating barrier is radially to be divided into multistage; Be provided with the separator of insulating material between each section; Every section outermost layer capacitance plate and next section first capacitance plate intercropping electrically connect.
Except that above-mentioned essential features, in specific implementation process, also can replenish following technology contents:
The number of plies of every section condenser type insulation system is less than 80.
Every section first capacitance plate is to be made by the rigid material of non-magnetic conduction.
Be provided with the connector of high-strength insulating material between per two sections, and fixing with this connector with two sections.
The inserts with the solid macromolecule insulating material is filled in two intersegmental spaces.
Advantage of the present utility model is: quality is little, antifouling property and stressing conditions are good, the dislocation of insulating barrier concentration of local does not take place.
The utility model is described in further detail below in conjunction with drawings and Examples:
Description of drawings:
Fig. 1 is the oil-filled ceramic bushing of a kind of condenser type insulation system of prior art.
Fig. 2 is a kind of dry-type high-voltage sleeve pipe of making the condenser type insulation system with the polytetrafluoroethylene film insulating material of prior art.
Fig. 3 is that the another kind of prior art is made the condenser type insulation system replaces porcelain bushing with the high-intensity resin pipe dry-type high-voltage sleeve pipe with the polytetrafluoroethylene film insulating material.
Fig. 4 is the schematic diagram that the dislocation of insulating barrier concentration of local takes place in Fig. 3 dry-type high-voltage sleeve pipe.
Fig. 5 is the structural representation of dry-type high-voltage sleeve pipe of the present utility model.
Figure 5 shows that a kind of embodiment of dry-type high-voltage sleeve pipe provided by the utility model, its center has a conductor 11, the conductor 11 outer condenser type insulating barriers 12 that are provided with, the condenser type insulating barrier 12 outer sheaths 13, the intrinsic full skirt 14 of sheath 13 overcoats of being provided with; The utility model difference with the prior art is that this condenser type insulating barrier 12 is radially to be divided into multistage; The separator that insulating material is arranged between each section; Every section outermost layer capacitance plate 15 electrically connects with next section first capacitance plate 16 intercropping.The inhomogeneous insulating barrier generation concentration of local inconsistent phenomenon that causes of prestressing force that is produced for avoiding polytetrafluoroethylene film to be stretched, the number of plies of every section condenser type insulating barrier is less than 80.This is because the number of plies that holds is few more, be not prone to the concentration of local dislocation more, but it is relevant with withstand voltage to hold the number of plies, under the condition of certain withstand voltage, need certain number of plies that holds, can not be very little, for solving this contradiction, adopt the method for segmentation, each section number of plies is no more than 80, and the summation of each section number of plies can substantially exceed 80 layers and meet the desired number of plies of withstand voltage.For improving stressing conditions, every section first capacitance plate 16 is to be made by the rigid material of non-magnetic conduction, generally can adopt non-magnetic conductive metal material, is layed in outside it as adopting its first capacitance plate of insulating material.The connector 17 that is provided with high-strength insulating material between per two sections is fixed.The filler 18 with the solid macromolecule insulating material is filled in two intersegmental spaces.
