Abstract
The invention discloses a major loop contact terminal of an SF6 tank circuit breaker. The major loop contact terminal comprises a contact finger seat, a contact terminal, a plurality of contact fingers and a contact finger cover, wherein the rear ends of the contact fingers are stuck on the outer surface at the end part of the contact finger seat; the inner surface at the rear end of the contact finger cover tightly presses the rear ends of the contact fingers on the outer surface at the end part of the contact finger seat; the contact fingers are made of an elastic material; and the front ends of the contact fingers are elastic contact ends. The invention simplifies the contact terminal structure and reduces the non-uniform state of contact resistance and an internal electric field. The stressed contact pressure of each contact finger is guaranteed to be uniform by utilizing the elastic deformation of the material of the contact fingers, and the reliability is greatly improved.
Description
Technical field
The present invention relates to a kind of circuit breaker components, relate in particular to a kind of SF
6The major loop contact terminal of potting breaker.
Background technology
The SF6 potting breaker is the force device of using always.In the prior art, the major loop contact terminal of SF6 potting breaker adopts traditional flower basket type assembling, has the multi-disc fingertip to connect with spring, and fingertip sheet and radome are used thread connection.
There is following shortcoming at least in above-mentioned prior art:
Be difficult to guarantee that the fingertip sheet normally contacts with contact, make the fingertip sheet carry out divide-shut brake when action discontinuity, and influence the through-flow and heat conductivility of fingertip sheet, and structure be loaded down with trivial details, the internal electric field skewness.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, contact is stressed evenly, the SF of dependable performance
6The major loop contact terminal of potting breaker.
The objective of the invention is to realize through following technical scheme:
SF of the present invention
6The major loop contact terminal of potting breaker; Comprise fingertip seat, contact; It is characterized in that; Also comprise multi-disc fingertip and fingertip cover, the rear end of said fingertip is attached to the outer surface of the end of said fingertip seat, and the inner surface of the rear end of said fingertip cover is pressed on the rear end of said fingertip the outer surface of the end of said fingertip seat;
The material of said fingertip is an elastomeric material, and the front end of said fingertip is the Elastic Contact end.
Technical scheme by the invention described above provides can be found out, SF of the present invention
6The major loop contact terminal of potting breaker, because the rear end of fingertip is attached to the outer surface of the end of fingertip seat, the inner surface of the rear end of fingertip cover is pressed on the rear end of fingertip the outer surface of the end of fingertip seat; The material of fingertip is an elastomeric material, and the front end of fingertip is the Elastic Contact end.Simplified structure of contact terminal, reduced the inhomogeneous state of contact resistance and internal electric field, utilized the strain of fingertip material itself, guaranteed that every fingertip contact pressure is stressed evenly, reliability improves greatly.
Description of drawings
Fig. 1 is SF of the present invention
6The structural representation of the major loop contact terminal of potting breaker.
Embodiment
SF of the present invention
6The major loop contact terminal of potting breaker; Its preferable embodiment is as shown in Figure 1, comprises fingertip seat 1, contact 4, also comprises multi-disc fingertip 2 and fingertip cover 3; The rear end of fingertip 2 is attached to the outer surface of the end of fingertip seat 1, and multi-disc fingertip 2 can evenly distribute along the periphery of the end of fingertip seat 1.
The inner surface of the rear end of fingertip cover 3 is pressed on the rear end of fingertip 2 outer surface of the end of fingertip seat 1; The material of fingertip 2 can be elastomeric material, and the front end of fingertip 2 is the Elastic Contact end, can with contact 4 Elastic Contact or disconnection.
Specifically can be provided with groove at the outer surface of the end of fingertip seat 1, the rear end of fingertip 2 places groove, and the outer surface of the end of the upper surface of fingertip 2 and fingertip seat 1 flushes with or slightly higher than the outer surface of the end of fingertip seat 1.
Like this, the outer surface interference fit of the end of the inner surface of the rear end of fingertip cover 3 and fingertip seat just can be pressed on the end of fingertip seat 1 together with fingertip 2.The outer surface of the end of the inner surface of the rear end of fingertip cover 3 and fingertip seat can adopt the hot working assembling.
The SF of the utility model
6The major loop contact terminal of potting breaker; Adopt the self-reliance contact, simplified structure of contact terminal, fingertip adopts integrated design; The performance of contact material itself has guaranteed the strain and the stressed consistency of each sheet fingertip; Utilize the strain of fingertip material itself, guarantee that every fingertip contact pressure is stressed evenly, reliability improves greatly.
Fingertip cover and fingertip adopt the hot working assembling without thread connection, have reduced the inhomogeneous state of contact resistance and internal electric field, and Electric Field Distribution is good.
The above; Be merely the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technical staff who is familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
