Abstract
The utility model relates to a static contact of a high-voltage switch. The static contact is of a cylindrical hollow tube structure; the thickness of the tube wall at the front end of the static contact is smaller than that of the tube wall at the rear end; and the outer side at the top part of the front end of the static contact is a spherical surface. By changing the slope at the front end into the spherical surface, the resistance applied to the static contact when the static contact is inserted is balanced, so that the inserting resistance is small, connection between the static contact and a plum blossom contact is facilitated, and backward bending of the switch is effectively restrained.
Description
Technical field
The utility model relates to a kind of accessory of high-voltage switch gear, especially a kind of fixed contact of high-voltage switch gear.
Background technology
The fixed contact of high-voltage switch gear is used for being connected with Mume flower contact, and Mume flower contact is enclosed within outside fixed contact, by the spring on Mume flower contact, Mume flower contact closely is connected with fixed contact.For fixed contact can be inserted in Mume flower contact smoothly, the front end periphery of fixed contact is generally one and encloses the inclined-plane, but because the contact of Mume flower contact moves more outward, the fastening force that is subject to spring is larger, so it is still very large that the inclined-plane is subject to resistance in the second half section, still need very large thrust, and resistance greatly also can cause the switch layback.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and the fixed contact of the little high-voltage switch gear of a kind of resistance of pegging graft is provided.
For achieving the above object, the utility model adopts a kind of fixed contact of high-voltage switch gear, and fixed contact is the columnar hollow tubular construction, and the front tube wall thickness of fixed contact is less than the rear end tube wall, and the lateral surface of the front top of fixed contact is sphere.
The utility model further is set to described sphere and is comprised of two sections different spheres of radius, and the spherical radius in the outside is less than the spherical radius of inboard.
The utility model makes sphere into by the inclined-plane with front end, and the resistance that balanced fixed contact is subject to when inserting inserts resistance less, facilitates fixed contact to be connected connection with Mume flower contact, and has effectively suppressed the switch layback.
Description of drawings
Fig. 1 is the partial sectional view of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, specific embodiment of the utility model is a kind of fixed contact 1 of high-voltage switch gear, the structure of fixed contact 1 is the cylindrical hollow tubular construction, front end 2 pipe thicknesses of fixed contact 1 are less than rear end 3 pipe thicknesses, at step structure of fixed contact 1 inboard formation, the lateral surface at front end 2 tops of fixed contact 1 is sphere 4, and sphere 4 is comprised of two sections different spheres of radius, and sphere 41 radiuses in the outside are less than sphere 42 radiuses of inboard.
