Abstract
The utility model relates to a high-voltage switch electric contact structure, and particularly discloses a contact assembly structure. The contact assembly structure comprises a shielding conductor and a plurality of contact fingers and is characterized in that the contact fingers are connected end to end and clamped by contact finger springs, the clamped contact fingers are fixed inside the shielding conductor through multiple contact finger supporters, and the contact finger supporters are sequentially arranged inside the shielding conductor. The contact assembly structure is low in cost, simple and reliable in structure and convenient to assemble, the electric field is improved effectively, the structure is simplified, flow capacity of working current is improved, and electric stability and thermal stability when the contact assembly structure is impacted by short-circuit current are enhanced.
Description
(1) technical field
The utility model relates to a kind of high-voltage switch gear electric contact structure, particularly a kind of contact assembly structure.
(2) background technology
Present stage, 110 ~ 220KV level high-voltage switch gear main conductive circuit electrically contacts design and is the Mume flower contact structure.This project organization is complicated, electrically contact that pressure is inhomogeneous, the processing and manufacturing cost high, to the bad adaptability of operating current size, electronic stability and thermal stability during short-circuit current rush are undesirable.
(3) summary of the invention
The utility model is in order to remedy the deficiency of prior art, and a kind of simple in structure, contact assembly structure of being convenient to assemble is provided.
The utility model is realized through following technical scheme:
A kind of contact assembly structure; Comprise shielded conductor and fingertip; It is characterized in that: several fingertips join end to end and are clamped by the fingertip spring, and the fingertip of clamping is fixed on shielded conductor inside through the fingertip supporter, and a plurality of fingertip supporters are set in turn in the shielded conductor.
In the utility model, each fingertip is clamped by a fingertip spring, joins end to end, and is fixed on shielded conductor inside through the fingertip supporter, and a plurality of fingertip supporters are arranged in order, and forms a multi-level rounded contact assembly structure.
The more excellent scheme of the utility model is:
For guaranteeing the accuracy of fingertip supporter position in the shielded conductor, be provided with guide between the two fingertip supporters of said shielded conductor end.
The utility model cost is low, and is simple and reliable for structure, is convenient to assembling, effectively improved electric field, simplifies the structure, and improved the operating current through-current capability, electronic stability and thermal stability when having strengthened short-circuit current rush.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 looks generalized section for the master of the utility model;
Fig. 2 is the left TV structure sketch map of the utility model.
Among the figure, 1 shielded conductor, 2 fingertip supporters, 3 guides, 4 fingertips, 5 fingertip springs.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.This embodiment comprises shielded conductor 1 and fingertip 4, and several fingertips 4 join end to end and clamped by fingertip spring 5, and the fingertip 4 of clamping is fixed on shielded conductor 1 inside through fingertip supporter 2, and a plurality of fingertip supporters 2 are set in turn in the shielded conductor 1; Be provided with guide 3 between the two fingertip supporters 2 of said shielded conductor 1 end.
Each fingertip 4 is clamped by a fingertip spring 5, joins end to end, through fixing how shielded conductor 1 inside of fingertip supporter 2; Form a multi-level rounded contact assembly structure; Solved the contact pressure homogeneity question, improved electric field, simplified the structure; Improved operating current cocurrent flow ability, electronic stability and thermal stability when having strengthened short-circuit current rush.This design is mainly used in 110 ~ 220KV level high-voltage switch gear.
