Abstract
The utility model belongs to an electric connection point connecting structure for a high-voltage switch device, and particularly discloses a contact seat shielding device. The contact seat shielding device comprises a contact seat and is characterized in that the contact seat and a shielding cover are integrated into a whole, and symmetrical spring contact fingers are arranged on the contact seat. According to the contact seat shielding device, the structure is simple, the assembly is convenient, the cost is low, the circuit resistance value is stable, the through-current capability of the high-voltage switch device is improved, and the whole service life of the contact seat shielding device is prolonged.
Description
(1) technical field
The utility model belongs to high voltage switchgear and uses the electric contact syndeton, particularly a kind of shielding contact base device.
(2) background technology
At present, most of radome, flap fingertip, the contact base of adopting of the above electric pressure high-voltage switch gear shielding of 110KV contact base, the flap fingertip tightens with tightening spring.Its complex structure, manufacturing cost is high, wears no resistance, and assembling is taken a lot of work, and simultaneously, the heating that causes through big electric current for a long time is prone to cause that loop resistance increases.
(3) summary of the invention
The utility model is in order to remedy the deficiency of prior art, and a kind of shielding contact base device of simple in structure, dependable performance is provided.
The utility model is realized through following technical scheme:
A kind of shielding contact base device comprises contact base, it is characterized in that: it is one that said contact base and radome are assembled, and contact base is provided with the spring touch finger of symmetry.
The utility model is one with the radome and the contact base assembly of routine; Save radome and tightened spring; Replace the flap fingertip with spring touch finger, reduced major loop and electrically contacted tie point, help the through-current capability of high voltage switchgear major loop and the stability of loop resistance.
The more excellent scheme of the utility model is:
Be provided with hexagon socket head cap screw through packing ring on the said contact base, be convenient to installing and fixing of contact base.
Spring washer and plain washer that said packing ring is arranged for contact reduce the friction that bolt receives, and its damage is reduced.
The utility model is simple in structure, and is easy to assembly, and cost is low, and the loop resistance value stabilization helps improving the high voltage switchgear through-current capability and prolongs bulk life time.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model.
Among the figure, 1 contact base, 2 spring touch fingers, 3 hexagon socket head cap screws, 4 packing rings.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the utility model.This embodiment comprises contact base 1, and it is one that said contact base 1 is assembled with radome, and contact base 1 is provided with the spring touch finger 2 of symmetry; Be provided with hexagon socket head cap screw 3 through packing ring 4 on the said contact base 1; Spring washer and plain washer that said packing ring 4 is arranged for contact.
The radome and contact base 1 assembly of routine are one; Save radome and tightened spring; Replace the flap fingertip with spring touch finger 2, reduced major loop and electrically contacted tie point, help the through-current capability of high voltage switchgear major loop and the stability of loop resistance.The design is mainly used in the electric switch equipment of 126KV and above electric pressure.
