Abstract
The invention discloses a clamping plate type tulip contact of an SF6 composite apparatus. The clamping plate type tulip contact comprises a movable contact body and a fixed contact body. The fixed contact body comprises a contact finger base and a plurality of contact fingers. An upper insulating clamping plate and a lower insulating clamping plate are fixed to the contact finger base. The contact fingers are arranged between the upper insulating clamping plate and the lower insulating clamping plate. The upper insulating clamping plate and the lower insulating clamping plate are of a split structure or an integrated structure. The contact fingers are distributed to form a plum blossom shape. One or two circles of contact finger springs are wound on the periphery of the contact fingers. A shielding cover is fixed to the contact finger base. The upper edge of the shielding cover is buckled on a step of the upper surface of the upper insulating clamping plate. The upper insulating clamping plate and the lower insulating clamping plate are respectively made of polytetrafluoroethylene. The clamping plate type tulip contact is low in material consumption, compact in structure, flexible in contact finger movement and good in electric field distribution.
Description
Technical field
The present invention relates to a kind of SF6 combined electrical apparatus, relate in particular to a kind of clamping plate type Mume flower contact of SF6 combined electrical apparatus.
Background technology
The Mume flower contact of the electrical connection of 110KV combined electrical apparatus major loop motion at present use, adopts traditional flower basket type assembling, has multi-disc fingertip stainless steel stent and spring bolts assemblies.This structure can not guarantee that contact finger piece normally contacts with main contact, make contact discontinuity in the time 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, not arc ablation resistance, when there will be point discharge after fingertip ablation, has destroyed the Electric Field Distribution in combined electrical apparatus.
Summary of the invention
The object of this invention 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 object of the invention is to be achieved through the following technical solutions:
The clamping plate type Mume flower contact of SF6 combined electrical apparatus of the present invention, comprise moving contact, fixed contact, described fixed contact comprises button contact base, multiple 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.
As seen from the above technical solution provided by the invention, the clamping plate type Mume flower contact of the SF6 combined electrical apparatus that the embodiment of the present invention 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.

Embodiment
To be described in further detail the embodiment of the present invention below.
The clamping plate type Mume flower contact of SF6 combined electrical apparatus of the present invention, its preferably embodiment be:
Comprise moving contact, fixed contact, described fixed contact comprises button contact base, multiple 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 multiple fingertip is plum blossom-shaped and distributes, and the outer rim of multiple 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 invention, for the major loop motion electrical connection of SF6 combined electrical apparatus, 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.Advantage of the present invention is: materials are few, compact conformation, has reduced the height of the plum blossom button contact base of static connection, and 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 when 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 Mume flower contact of combined electrical apparatus major loop motion electrical connection 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, in the time that 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; only for preferably embodiment of the present invention, but protection scope of the present invention is not limited to this, is anyly familiar with in technical scope that those skilled in the art disclose in the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claims.
