Abstract
The utility model discloses a fixed contact structure. The structure comprises a fixed contact base, supporting springs, inner hexagon screws and moving contact plates, wherein the fixed contact base is in a U shape with a rightward opening, the moving contact plates comprise an upper moving contact plate and a lower moving contact plate, the upper moving contact plate and the lower moving contact plate are respectively located on the inner sides of an upper section horizontal portion and a lower section horizontal portion, the upper section horizontal portion and the lower section horizontal portion of the fixed contact base are provided with screw installation holes, end portions of the inner hexagon screws inserted into the screw installation holes are connected in the moving contact plates in a rotating mode, horizontal contact surfaces of the moving contact plates and the fixed contact base are respectively provided with spring holes, and the supporting springs which enable the moving contact plates and the fixed contact base to be in elastic contact are installed in the spring holes. The fixed contact structure has the advantages that the problems that contact pressure is not uniform and a watchband contact clamps and damages a silver plating surface of a moving contact are solved, an assembly and buffer area is increased, sliding friction force caused by separation and combination of a fixed contact and the moving contact is reduced, an electric field is improved, the cost is saved, the contact surface of the moving contact and the fixed contact is increased, the circulation capability of the working current is improved, and the electric stability and the heat stability during short-circuit current compact are strengthened.
Description
Technical field
The utility model belongs to the high-voltage switch gear electric contact structure, relates to a kind of static contact structure.
Background technology
Present stage, the HGIS main conductive circuit of 145kV and following electric pressure electrically contacts design and is embedded watchband fingertip structure.This project organization difficulty of processing is big, electrically contact pressure inhomogeneous, do not have buffering area be prone to take place that catching phenomenon, operating mechanism motor are prone to burn because of operand power increases, the processing and manufacturing cost is expensive, to the bad adaptability of operating current size, electronic stability and thermal stability during short-circuit current rush are not firm.
Summary of the invention
The utility model provides the static contact structure that a kind of cost is low, simple and reliable for structure, be convenient to assemble in order to remedy the deficiency of prior art.
The utility model is realized through following technical scheme:
The static contact structure of the utility model; Comprise the stationary contact headstock, it is opening U-shaped to the right, and its special character is: also comprise support spring, soket head cap screw, movable contact plate; The movable contact plate is two up and down; Lay respectively at the inboard of the two sections horizontal component of stationary contact headstock, the two sections horizontal component of stationary contact headstock all is provided with screw mounting hole, and the soket head cap screw end of pegging graft in this hole is screwed in the movable contact plate; The horizontal contact-making surface of movable contact plate and stationary contact headstock is provided with spring eye separately, and the support spring that makes the two Elastic Contact is housed in the spring eye.
The static contact structure of the utility model has plain washer and elastic washer between soket head cap screw and the stationary contact headstock.
The beneficial effect of the utility model is, cost is low, simple and reliable for structure, be convenient to assembling, 2 movable contact plates separately by 4 springs and M10 * 20 soket head cap screws and flat, play packing ring and lock, and be rich in relaxation power, form one and be equivalent to watchband fingertip assembled construction.When having solved contact pressure non-uniformity problem and watchband fingertip and clamping stagnation destroys moving contact silvered face problem, increase the assembling buffering area, having reduced dynamic/static contact divides fashionable force of sliding friction; Improved electric field, practiced thrift cost, increased the dynamic/static contact contact-making surface, improved the operating current through-current capability, electronic stability and thermal stability when having strengthened short-circuit current rush.This product is mainly used in the HGIS of 145kV and following electric pressure.
