Background technology
High voltage device is the biggest, is often associated with strong-electromagnetic field impact during work, for improving characteristic, it is to avoid the interference of corona, high tension unit often has radius of curvature relatively big, and ganoid screening electrodes.The high-voltage electrode commonly used at present most, is usually by aluminum alloy materials or the solid or hollow metal spheroid of special steel material turnery processing, and less voltage equalizing ball is the most solid, and major diameter voltage equalizing ball majority is hollow metal spheroid.Medicine ball good mechanical property, processing technique is complicated, and waste of material is big, cost intensive；Hollow ball mechanical performance is poor, easily deforms and damages, thus reduces uniform voltage function.Common metal sphere is the most affected by environment and corrosion, and service life is shorter.
Summary of the invention
This utility model is for solving above-mentioned technical problem, provide a kind of high voltage spheric electrode, including electrode column, it is characterized in that: also include spheroid, the hole for filling filler is offered outside spherical shell, ball interior is filled up completely with composite insulating material, and electrode column is arranged in aperture, is connected as an entirety by hot setting and ball interior.
Described high voltage spheric electrode, can meet the occasions such as high voltage transformer, alternating current-direct current high voltage power supply, high voltage test instrument and meter and use.
Described spheroid is that spheroid decorated by rustless steel, inside is hollow-core construction, due to spheroid, to have curvature big, the features such as smooth surface, the distribution of high voltage electric field can be improved, prevent exposed high voltage component (or electrode) surface from occurring because electric field intensity is too high corona discharge that flashover (arc discharge) even occurs.
Described compound inslation packing material, for epoxy resin and silicon powder composite, is referred to as insulation perfusion powder.For fixed electrode post, ball interior is filled up completely with simultaneously.Both ensure that the profile not malleable of traditional solid spheroid, and can guarantee that again stainless steel casing obtains catch light cleanliness spheroid through simple polishing, there is extremely strong decay resistance, it is possible to achieve the good response that high voltage is all pressed.
Described electrode column, uses copper as electrode material, and it has good cutting ability and electric conductivity.Electrode column connecting portion can be processed into female thread structure or external thread structure as required, meets the use demand of different occasion.
The utility model has the advantage of: 1. ball material is that spheroid decorated by rustless steel, and inside is hollow-core construction, and surface smoothness is high, and can be according to all pressing demand, easily from the stainless steel ball that Market Selection amount of curvature is different；2. internal filled composite insulant, filling process is easy and simple to handle, and the later stage connects easily, and this material is combined densification with spheroid inner surface, and dielectric properties are good, Heat stability is good, and hardness is high, and use process is not susceptible to deformation；3. electrode column uses copper product, simple shape, has good cutting ability and electric conductivity；4. overall cost is cheap, and cost performance is high.
Accompanying drawing explanation
Fig. 1 is longitudinal section of the present utility model.
In figure: 1-spheroid, 2-epoxy composite insulant, 3-electrode column.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is described in further detail.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
Composition and structure based on this high voltage spheric electrode, the shell of this spheric electrode uses market widely used decoration rustless steel spheroid, spherome surface self smoother, without secondary operations, abundant raw materials is readily available, size Selection scope is wide, and the occasion that can meet different voltage uses.Have a hole on spheroid, be used for placing electrode column, simultaneously facilitate the filling of epoxy resin and silicon powder composite insulating material.After adding heat fusing, just easily can inject in spheroid, then electrode column, composite and spheroid integral high-temperature be solidified by thermosetting process, whole processing technology is the easiest, and easy for installation.Core of the present utility model is to change traditional integral ball structure, uses cheap materials, and reduces manufacturing cost, and by simpler production technique, makes the high voltage spheric electrode of function admirable.
As shown in drawings, spheroid 1 uses rustless steel decoration spheroid as shell, owing to have employed smooth, spherical structure, the distribution (all pressures) of high voltage electric field can be improved, prevent exposed high voltage component (or electrode) surface from occurring because electric field intensity is too high corona discharge that flashover (arc discharge) even occurs.Ball interior fills epoxy composite insulating material 2, by composite insulating material, electrode column is closely coupled with spheroid.Described insulation filling material, for epoxy resin and silicon powder composite.For fixed electrode post, ball interior is filled up completely with simultaneously.Both ensure that the profile not malleable of traditional solid spheroid, and can guarantee that again stainless steel casing obtains catch light cleanliness spheroid through simple polishing, there is extremely strong decay resistance, it is possible to achieve the good response that high voltage is all pressed.
Ensure that high voltage spheric electrode has good structural behaviour, it is simple to install and operate.There is good shape stability simultaneously, in use will not deform, it is achieved the good response that high voltage is all pressed.Electrode column 3 selects copper as electrode material, has good machine cut performance and electric conductivity.
Operation principle of the present utility model is: high voltage spheric electrode sphere structure uses rustless steel decoration spheroid as shell, owing to have employed smooth, spherical structure, the distribution (all pressures) of high voltage electric field can be improved, prevent exposed high voltage component (or electrode) surface from occurring because electric field intensity is too high corona discharge that flashover (arc discharge) even occurs.Ball interior is closely coupled with spheroid by electrode column by composite insulating material.Ensure that high voltage spheric electrode has good structural behaviour, it is simple to install and operate.There is good shape stability simultaneously, be in use not susceptible to deformation, it is achieved the good response that high voltage is all pressed.Electrode column selects copper material, has good machine cut performance and electric conductivity.
