Abstract
The utility model discloses a grounding inner-shielding device of a high-voltage insulating sleeve. The grounding inner-shielding device comprises a cylindrical grounding electrode, metal brackets and an annular electrode, wherein the cylindrical grounding electrode is connected with a grounding flange, the annular electrode is installed above the cylindrical grounding electrode, and the annular electrode is connected with the cylindrical grounding electrode below through three tiny metal brackets so at to be in the same electric potential. The grounding inner-shielding device has the advantage of uniform electric field distribution.
Description
Technical field
The utility model relates to a kind of High-Voltage Electrical Appliances assembly, particularly a kind of grounding inner shield device of high-tension insulating bushing.
Background technology
High-tension insulating bushing is the critical elements in Cubicle Gas-Insulated Switchgear (GIS), when high pressure current－carrying conductor is introduced in metal enclosed tank body, uses high-tension insulating bushing can reduce electric field strength.The insulation effect of high-tension insulating bushing is significant for the reliability service of whole generalized information system.
Compare SF with other insulating sleeve
6the features such as that gas-filled bushing has is light, little, simple, honest and clean, technique is convenient, especially in insulation reliable, without partial discharge, disturb, make it to become first-selected insulation component.
Along with the raising of insulating sleeve electric pressure, the inhomogeneities of the Electric Field Distribution between center conductor and ground connection flange becomes outstanding.Set up grounding inner shield to improve Electric Field Distribution herein, significant for the reliability that reduces to insulate in insulator bottom diameter, raising insulator.
Utility model content
Technical problem to be solved in the utility model is the grounding inner shield device that the uniform high-tension insulating bushing of a kind of Electric Field Distribution will be provided.
In order to solve above technical problem, the utility model provides a kind of grounding inner shield device of high-tension insulating bushing, this grounding inner shield device comprises tubular grounding electrode, metallic support and annular electrode, tubular grounding electrode is connected with ground connection flange, tubular grounding electrode top is provided with a round loop electrode, round loop electrode is connected with the tubular grounding electrode of below by three tiny metallic supports, makes in same current potential.
Described metallic support is hollow metal bar.
Superior effect of the present utility model is:
1) due to the existence of round loop electrode, the height of tubular grounding electrode can suitably reduce, thereby reaches the object of saving manufactured materials;
2) pass through grounding electrode height, internal diameter; Round loop electrode height, internal diameter and the isoparametric adjustment of distance between the two improve near the Electric Field Distribution whole grounding inner shield, thereby reach the object that reduces the tangential electric field strength on porcelain piece surface in air.
Accompanying drawing explanation

Embodiment
Refer to shown in accompanying drawing, the utility model will be further described.
As shown in Figure 1, the top of high-tension insulating bushing comprises terminal block 1, a pair of grading ring 2 and upper flange 3, and they are high potential; High-tension insulating bushing bottom comprises round loop electrode 5, grounding electrode 6 and ground connection flange 7; Whole insulating sleeve is insulator 4 sealings by ceramic full skirt, and inside is filled with the SF under certain air pressure
6gas.
As shown in Figure 2, tubular grounding electrode 6 is connected with ground connection flange 7, tubular grounding electrode 6 tops are provided with a round loop electrode 5, round loop electrode 5 is connected with the tubular grounding electrode 6 of below by three tiny metallic supports 8, tubular grounding electrode 6 is connected with ground connection flange 7 again, so they are earth potential.Due to the existence of top round loop electrode 5, the height of tubular grounding electrode 6 can suitably reduce, thereby reaches the object of saving manufactured materials.Pass through again tubular grounding electrode 6 height, internal diameter, round loop electrode 5 height, internal diameter and the isoparametric adjustment of distance between the two improve near the Electric Field Distribution whole grounding inner shield, thereby reach the object that reduces the tangential electric field strength on porcelain piece surface in air.
