Technical field
This utility model relates to a kind of bushing core body making high-tension insulator, the capacitance plate locating support of a kind of dry high voltage casing 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.
The circular tube shaped net cylinder being made up of metal gauze due to the capacitance plate on bushing core body, each layer in bushing core body
Capacitance plate should be at concentrically ringed position, so can ensure the Electric Field Distribution of capacitance plate, improves the dielectric strength of bushing core body.And the position that each layer capacitance screen is in putting into casting mold, naturally also should be to maintain on concentrically ringed position with contact tube.But there is presently no preferable bracing frame, therefore, during casting resin, capacitance plate is possible to produce displacement or deformation, thus affects the Electric Field Distribution of capacitance plate, correspondingly reduces the dielectric strength of bushing core body.
Utility model content
The purpose of this utility model is just to provide the capacitance plate locating support of a kind of dry high voltage casing core body, with the problem solving to cause the uneven dielectric strength with the bushing core body produced of capacitance plate Electric Field Distribution to reduce because lacking capacitance plate bracing frame.
This utility model is achieved in that the capacitance plate locating support of a kind of dry high voltage casing core body, semicircle contour body including two relative fastenings, the inner headed face of each semicircle contour body is provided with at least two axially distributed insulation of row and props up pawl, each insulation is propped up pawl and is directed to the center of circle of place disc, insulation pawl quantity in each column insulation pawl is identical with the quantity of the capacitance plate of required support, each insulation prop up pawl arrange position corresponding to required support capacitance plate next-door neighbour port turnup limit position, it is that the center of circle line of capacitance plate enabling required support coincides with the center of circle line of described semicircle contour body that the rational height of pawl is propped up in each insulation.
The internal diameter of two described semicircle contour bodies is identical, external diameter is identical, length is identical.
The involutory edge of described semicircle contour body is provided with draw-in groove or card rib.
This utility model is the positioning supporting frame of the capacitance plate for the step distribution made by metal gauze, by insulation the pawl in same position on each row insulation pawl, the location on the port turnup limit of the capacitance plate on position is supported, the capacitance plate that can make the step distribution being socketed on contact tube all keeps concentrically ringed position with contact tube, so, during casting resin, in step, each layer capacitance screen of distribution will produce displacement or deformation, avoid the situation causing capacitance plate local deformation because of injection pressure, avoid the touching phenomenon of adjacent capacitor screen, effectively improve capacitance plate Electric Field Distribution on bushing core body, improve the integral insulation intensity of bushing core body.
