Abstract
The utility model discloses a kind of disc insulator of a kind of disc insulator, it is characterized in that, comprise circular body of epoxy resin, body of epoxy resin is provided with 3 center conductors, and center conductor is uniformly distributed around the body of epoxy resin center of circle.The utility model reduces basin volume size, and eliminate the aluminium ring of outer rim, reduce production cost, and reduce assembly space, structure is compacter, meets the insulation requirements under 252kV electric pressure.
Description
Technical field
The utility model relates to a kind of three-phase combined type type disc insulator, is applied to High-voltage Switchgear Industry SF6 gas-insulated and closes in combined electric.
Background technology
Disc insulator is used in a large number in high voltage electric appliance.Disc insulator main rising in electric equipment products supports and insulation function; Various product is designed to variform product according to own structural characteristics.In high pressure SF6 gas-insulated product, most disc insulator all adopts single-phase monotubular or three pole band aluminium ring structures, also have three pole conductors of some three-phase combined types press yi word pattern arranged, or presses isosceles triangle layout, its outside dimension is very large, reaches the bulky size of φ 920.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of compact conformation, insulator that size is less.
In order to solve the problem, the utility model provides a kind of disc insulator, it is characterized in that, comprises circular body of epoxy resin, and body of epoxy resin is provided with 3 center conductors, and center conductor is uniformly distributed around the body of epoxy resin center of circle.
Preferably, the corresponding center conductor place of described body of epoxy resin is provided with bulge-structure, and 3 bulge-structures are positioned at the same side of body of epoxy resin.
More preferably, the gradient between described bulge-structure and body of epoxy resin center is 40 °.
Preferably, the diameter of described body of epoxy resin is 760mm, and thickness is 73 ~ 75mm.
Preferably, described body of epoxy resin edge is evenly equipped with metal bolts.
More preferably, described body of epoxy resin edge is evenly equipped with circular hole.
In the utility model, 3 center conductors form three pole conductors, and three is that equilateral triangle is arranged; One side is protruding, and outer ring, without aluminium ring, forms three boss around three center conductors, and boss, by certain angle of inclination, making every phase conductor to there being enough surface insulation distances between periphery and other phase, ensure that basin conductor insulation needs; Circular arc, groove that the fluctuating of three-phase combined type type basin abutment surface does not wait, the air-tightness meeting basin requires and requirement of strength, changes basin Electric Field Distribution situation.Circular hole two kinds of forms with circular hole and can be with in three-phase disc insulator surface, and the basin of band circular hole can play ventilation, insulation, supporting role; Basin not with circular hole then can play trapping effect.
The utility model reduces basin volume size, and eliminate the aluminium ring of outer rim, reduce production cost, and reduce assembly space, structure is compacter, meets the insulation requirements under 252kV electric pressure.
Accompanying drawing explanation
The structural representation of a kind of disc insulator that Fig. 1 provides for the utility model;
Fig. 2 is the cutaway view at symmetry axis place in Fig. 1.
Embodiment
For making the utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment
As shown in Figure 1-2, be the structural representation of a kind of disc insulator that the utility model provides, comprise circular body of epoxy resin 2, the diameter D of body of epoxy resin 2 is 760mm, and thickness d is 73 ~ 75mm.Body of epoxy resin 2 is provided with the same side that 3 bulge-structures, 4,3 bulge-structures 4 are positioned at body of epoxy resin 2, and centered by body of epoxy resin 2 center of circle, surround into equilateral triangle layout.Gradient α between bulge-structure 4 and body of epoxy resin 2 center is 40 °.Body of epoxy resin 2 edge is evenly equipped with metal bolts 3 and circular hole 5, and metal bolts 3 and circular hole 5 interval are arranged, circular hole 5 can be used for ventilation, insulation or supports.
