Abstract
The utility model discloses a kind of anti-corona cover, described anti-corona cover includes upper cover and lower cover, is connected between described upper cover and lower cover by fixing gold utensil, and the joint portion outer surface processing of upper cover and lower cover is smooth, note type screen outside upper cover and lower cover, the material of described screen is set to insulating paper.Before the utility model construction, insulating paper is coordinated with anti-corona cover body, reduce the engineering time, avoid because technical staff's level of skill is different simultaneously and the insulation property of product are impacted.
Description
technical field:
The utility model relates to 110kV ~ 500kV oil immersion terminating insulation field of components, is specially a kind of anti-corona cover.
background technology:
All the time, 110kV ~ 500kV oil immersion terminal and GIS terminal use the cable joint of same configuration.But SF6 gas is different with the insulation tolerance of insulating oil, so SI semi-insulation parts need distinguish design.On oil immersion end product, anti-corona cover must be used to increase insulation property.The processing method of anti-corona cover is before: after the assembling of oil immersion terminal, for improving the insulation tolerance of anti-corona cover, need to carry out coil paper operation to anti-corona cover.But this processing method can produce larger aberrations in property because of the difference of the management condition of insulating paper or coil paper operator level of skill.
summary of the invention:
The utility model, for above weak point, provides a kind of anti-corona cover, directly by screen together with anti-corona cover body note type, use convenient.
The utility model solves the technical scheme that its technical problem adopts: a kind of anti-corona cover, described anti-corona cover includes upper cover and lower cover, connected by fixing gold utensil between described upper cover and lower cover, the joint portion outer surface processing of described upper cover and lower cover is smooth, note type screen outside described upper cover and lower cover, the material of described screen is set to insulating paper.
Before the utility model construction, insulating paper is coordinated with anti-corona cover body, reduce the engineering time, avoid because technical staff's level of skill is different simultaneously and the insulation property of product are impacted; Parts after shaping are observed through X ray, and insulating paper inside or the defect such as bubble-free, foreign matter between insulating paper and shading ring, meet the instructions for use of JB/T 8318-2007 " transformer molded part " standard;
The parameters such as insulating layer material is insulating paper, the electrical strength in this insulating paper oil meet IEC 60664-1 standard, with anti-corona cover with the use of after meet the instructions for use of 110kV ~ 500kV oil immersion terminal;
The data drawn by electrical test meet IEC 62067 standard, use the anti-corona cap assembly of insulating paper screen to meet the service requirement of 110kV ~ 500kV oil immersion terminal.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is using state figure of the present utility model.
1 is insulating paper
2 is fixing gold utensil
3 is shading ring
4 is anti-corona cover.
Embodiment:
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
Be illustrated in figure 1 a specific embodiment of the present utility model, a kind of anti-corona cover, described anti-corona cover includes upper cover and lower cover (shading ring about 3 two parts), is connected between described upper cover and lower cover by fixing gold utensil 2; The joint portion outer surface processing of described upper cover and lower cover is smooth, and note type screen outside upper cover and lower cover, the material of described screen is set to insulating paper 1.Upper and lower two shading rings are connected by fixing gold utensil, after insulating paper note type, forms the utility model product-anti-corona cover.
Be illustrated in figure 2 the anti-corona assembled state covered in oil immersion end product of the utility model product.Described anti-corona covering on before assembling is constructed will carry out outward appearance confirmation, cleaning work, ensure that the quality stability after assembling product, improves the insulation property of oil immersion terminal.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection range of the present utility model.
