The static contact includes a contact finger seat and a plurality of contact fingers; an upper insulated clamping plate and a lower insulated clamping plate are fixed at the contact finger seat; and the contact fingers are arranged between the upper insulated clamping plate and the lower insulated clamping plate. The upper insulated clamping plate and the lower insulated clamping plate have a split structure or integrated structure. The plurality of contact fingers are distributed in a plum blossom shape; and outer edges of the multiple contact fingers are encircled by one loop or two loops of contact finger springs. A shielding case is fixed at the contact finger seat; and the upper edge of the shielding case is buckled at the step of the upper surface of the upper insulated clamping plate. The upper insulated clamping plate and the lower insulated clamping plate are made from teflon. The provided contact has advantages of less materials, compact structure, flexible contact finger motion, and good electric field distribution.
Description
Technical field
The utility model relates to a kind of SF6 combined electrical apparatus, relates in particular to a kind of clamping plate type Mume flower contact of SF6 combined electrical apparatus.
Background technology
110KV combined electrical apparatus major loop motion is at present electrically connected to the Mume flower contact of use, adopts traditional flower basket type assembling, has stainless steel stent and spring bolts assemblies for multi-disc fingertip.This structure can not guarantee that contact finger piece normally contacts with main contact, make contact discontinuity when carrying out divide-shut brake action, contact can be often stuck, the phenomenon such as can not rebound, and affect the through-flow and heat conductivility of contact, arc ablation resistance not there will be point discharge after fingertip ablation, has destroyed the Electric Field Distribution in combined electrical apparatus.
Utility model content
The purpose of this utility model is to provide that a kind of materials are few, compact conformation, the motion of plum blossom fingertip flexibly, the clamping plate type Mume flower contact of SF6 combined electrical apparatus that Electric Field Distribution is good.
The purpose of this utility model is achieved through the following technical solutions:
The clamping plate type Mume flower contact of SF6 combined electrical apparatus of the present utility model, comprise moving contact, fixed contact, described fixed contact comprises button contact base, a plurality of fingertip, is fixed with cleat insulator and lower cleat insulator on described button contact base, and described fingertip is arranged between described upper cleat insulator and lower cleat insulator.
The technical scheme being provided by above-mentioned the utility model can be found out, the clamping plate type Mume flower contact of the SF6 combined electrical apparatus that the utility model embodiment provides, owing to being fixed with upper cleat insulator and lower cleat insulator on button contact base, fingertip is arranged between cleat insulator and lower cleat insulator, materials are few, the motion of compact conformation, fingertip flexibly, Electric Field Distribution is good.
Accompanying drawing explanation
The structural representation of the clamping plate type Mume flower contact of the SF6 combined electrical apparatus that Fig. 1 provides for the utility model embodiment.

Embodiment
To be described in further detail the utility model embodiment below.
The clamping plate type Mume flower contact of SF6 combined electrical apparatus of the present utility model, its preferably embodiment be:
Comprise moving contact, fixed contact, described fixed contact comprises button contact base, a plurality of fingertip, is fixed with cleat insulator and lower cleat insulator on described button contact base, and described fingertip is arranged between described upper cleat insulator and lower cleat insulator.
Described upper cleat insulator and lower cleat insulator are Split type structure or integrative-structure.
Described a plurality of fingertip is plum blossom-shaped and distributes, and the outer rim of a plurality of fingertips is around a circle or two circle fingertip springs.
On described button contact base, be fixed with radome, the upper limb of described radome is buckled on the step of upper surface of described upper cleat insulator.
The material of described upper cleat insulator and lower cleat insulator is respectively polytetrafluoroethylene.
The clamping plate type Mume flower contact of SF6 combined electrical apparatus of the present utility model, major loop motion for SF6 combined electrical apparatus is electrically connected to, adopt the inserting mode of plum blossom fingertip and moving contact, and plum blossom fingertip and radome and conducting rod are without thread connection, adopt the board-like assembling of insulating blanked clamper, cleat insulator adopts the polyfluortetraethylene plate of high resistance to ablation, self-lubricating material.The utility model has the advantages that: materials are few, compact conformation, reduced the height of the plum blossom button contact base of static connection, plum blossom fingertip moves flexibly in cleat insulator (self-lubricating material), fingertip and radome arc ablation resistance.Electric Field Distribution is good, and when moving contact during reciprocating motion, can produce electric arc in clamping plate type plum blossom fingertip, cleat insulator can prevent that arc erosion from arriving plum blossom fingertip and radome, destruction Electric Field Distribution.
Specific embodiment:
As shown in Figure 1, the motion of combined electrical apparatus major loop is electrically connected to the Mume flower contact of use, adopts clamping plate type structure, and plum blossom fingertip is fixed on button contact base 3 by upper cleat insulator 10 and lower cleat insulator 4, make its structure very compact, fingertip 2 is free to slide in two clamping plate, has stopped the stuck problem of fingertip, when moving contact carries out divide-shut brake motion, the electric arc producing, all ablation, on resistant to elevated temperatures on cleat insulator 10, prevents ablation radome 1 and fingertip 2, has guaranteed being evenly distributed of electric field.
The above; it is only preferably embodiment of the utility model; but protection range of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claims.
