Abstract

The utility model discloses a lead angle-ring gasket for high-voltage power transformer insulation, which comprises a circular ring body and a cylinder-shaped folding body distributed at the edge portion of the circular ring body in surrounding mode. The circular ring body and the cylinder-shaped folding body are connected through an arc transition portion. The thickness of the arc transition portion is larger than that of the circular ring body and the cylinder-shaped folding body. A cylinder-shaped lead body is arranged on the circular ring body. The lead angle-ring gasket in a structure of a whole circle can be integrally processed by a wet process forming technology, and a technology of manual adhesion is omitted, thereby being more convenient to manufacture. The lead angle-ring gasket produced in this way can be fully attached to the top of a coil, local electric discharge phenomena can not be caused due to a fact that no gap exists, and a problem of blocking oil channel of the transformer does not exist. The lead angle-ring gasket is applicable to ultrahigh voltage and extra-high voltage transformers.

Description

High-tension electricity is transformer insulated with lead-in wire square ring sheet
Technical field
It is transformer insulated with lead-in wire square ring sheet that the utility model belongs to transformer insulated parts, particularly high-tension electricity.
Background technology
In the end of high-tension electricity transformer coil, Electric Field Distribution is very concentrated, and this just needs a kind of insulating material very reliably and is installed in the end, prevents to produce electric discharge phenomena because of insulating material appears puncturing in field intensity.In order to address the above problem, normally make several little square ring sheets with insulating material, again several little square ring sheets are pasted together successively, not only manufacture craft is loaded down with trivial details, and, the machining tolerance problem exposes because of causing adhesive, this kind square ring sheet may stop up the transformer oil duct in use, makes transformer the local overheating phenomenon occur, thereby influences useful life.
Summary of the invention
Problem to be solved in the utility model just provides, and high-tension electricity simple in structure, good insulating is transformer insulated with lead-in wire square ring sheet, overcomes the defective that existing square ring sheet may stop up the transformer oil duct in use.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: high-tension electricity is transformer insulated with lead-in wire square ring sheet, it is characterized in that: comprise circular body and be periphery, be connected by arc transition portion between described circular body and the cylindric bound edge body at the cylindric bound edge body at position, circular body edge.
Further, the thickness of arc transition portion is greater than the thickness of circular body and cylindric bound edge body.
Further, on circular body, be provided with cylindric lead-in wire body.
The beneficial effects of the utility model: the square ring sheet of completely circular structure can adopt the wet therapy forming process one to process, and has removed the technology of manually pasting from, makes convenient; The square ring sheet that processes like this is attached to overhang fully, very close to each otherly can not produce partial discharge phenomenon, does not have transformer oil duct blocking problem; Be applicable to superhigh pressure and extra-high voltage transformer.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model.
Embodiment
With reference to Fig. 1, high-tension electricity is transformer insulated with lead-in wire square ring sheet, comprises circular body 1 and is periphery at the cylindric bound edge body 3 at position, circular body 1 edge, is connected by arc transition portion 2 between described circular body 1 and the cylindric bound edge body 3; The thickness of arc transition portion 2 is greater than the thickness of circular body 1 with cylindric bound edge body 3.On circular body 1, be provided with cylindric lead-in wire body 4.Aspect selection, the special-purpose true qualities kp softwood pulp of the electric information of selecting for use the needlebush mixed material to produce has superpower insulation effect, strengthens the insulation electrical intensity of product, thereby guarantees product long-term safety, stable operation.
