Abstract
The utility model relates to an electric capacity screen structure of dry -type electric capacity type high -tension bushing core, straight tube form drum is made by woven wire to its structure, and two ports of drum are mutually perpendicular with the axial lead of drum, and the system has circular arc turnup limit respectively on two ports of drum. The utility model discloses a make drum, formation reel network management with woven wire, through make the turnup limit on the port of drum, make the port of drum become the turn -up port. The structural design of this kind of electric capacity screen, the whole mechanical strength of reel network management has effectively been improved, but also can make the aspect ratio of reel network management regular and even, be difficult to warp, each layer drum that can make the intussusception has avoided causing local deformation's the condition because of injecting glue pressure, adjacent woven wire's touching phenomenon has been avoided, and the product of making in the use, can also improve field distribution effectively, the point discharge phenomenon of flat mouthful of end of electric capacity screen has been avoided, the whole dielectric strength of the high -tension bushing core of making also has apparent improvement.
Description
Technical field
This utility model relates to a kind of bushing core body making high-tension insulator, the capacitive screen structure of a kind of dry-type capacitance type bushing core body.
Background technology
The 201410161508.X patent of the applicant's application, disclose the manufacture method of a kind of capacitive high voltage sleeve pipe core body, this invention is to arrange multiple concentric circular step at the casting die inwall of sleeve pipe core body, concentric circular step is utilized to fix conducting rod and the position of cylindric capacitance plate, evacuated casting resin and heating cure processing, conducting rod and capacitance plate are fixed together, become dry-type capacitance type bushing finished product.Compared with existing resin impregnated paper capacitor type bushing and glass fiber impregnating resin wound form capacitor type bushing, this manufacture method has that production efficiency is high, properties of product stable and the feature such as electric parameter is excellent.
But find in practice, metal gauze as the cylindric capacitance plate on bushing core body, its mechanical strength is relatively low, during casting resin glue, easily it is deformed, the metal gauze of the most adjacent interlayer, it is also possible to there is the phenomenon of touching, thus can greatly affect the Electric Field Distribution of capacitance plate, reduce the dielectric strength of bushing core body.
Utility model content
The purpose of this utility model is just to provide the capacitive screen structure of a kind of dry-type capacitance type bushing core body, to solve the problem affecting Electric Field Distribution and reduction bushing core body dielectric strength that existing cylindric capacitance plate causes because of deformation.
This utility model is achieved in that the capacitive screen structure of a kind of dry-type capacitance type bushing core body, metal gauze make straight tube-like cylinder, and two ports of cylinder are perpendicular with the axial line of cylinder, are formed respectively with circular arc turnup limit on two ports of cylinder.
This utility model, by making cylinder with metal gauze, forms reel webmaster；By making turnup limit on the port of cylinder, the port of cylinder is made to become crimping port.The structure design of this capacitance plate, it is effectively increased the overall mechanical strength of reel webmaster, but also the shape matching rule of reel webmaster can be made with uniform, it is not easy deformation, the each layer cylinder that can make intussusception avoids the situation causing local deformation because of injection pressure, avoid the touching phenomenon of adjacent metal silk screen, and products made thereby is in use, can also effectively improve Electric Field Distribution, avoiding the point discharge phenomenon of capacitance plate flat mouth end, the integral insulation intensity of made bushing core body is also significantly increased.
Accompanying drawing explanation
Fig. 1 is the structural representation of utility model.
Detailed description of the invention
As shown in Figure 1, this utility model is made straight tube-like cylinder 1 by metal gauze, the port plane of cylinder 1 both sides is perpendicular with the axial line of cylinder, being made circular arc turnup limit by the edge bent outward of metal gauze respectively on two ports of cylinder 1, the cross section on this circular arc turnup limit can be the structure of hollow circle.
Using this utility model as the capacitance plate of bushing core body, owing to preset capacitance plate belongs to wide arc gap, casting resin is conveniently dosed substantial amounts of filler, correspondingly reduce production cost, reducing dielectric loss the most simultaneously, improve Electric Field Distribution, properties of product are better than existing product.
The purposes of dry-type resin cast capacitive high voltage sleeve pipe core body is mainly considered for 35 220kV transformators, GIS high-voltage connection and wall bushing, its topmost feature is in process of production, the capacitance plate of bushing core body is preset in casting mold, disposable pressure casting resin, heating cure molding the most again.This processing technology is compared with glue impregnated paper production technology and glass fiber dipped winding process, its production efficiency can improve several times, and production cost can reduce by more than 50%, and quality technical process is the most controlled, key technical index is better than original two kinds of production technologies, and conforming product rate improves.At present, having carried out producing checking on the product of 35kV, its main performance index is higher than existing standard-required, and the product of production can meet the use needs on transformer station's high-voltage power transmission line road.
