Abstract
The invention discloses a straight-moving type three-station isolation switch. The straight-moving type three-station isolation switch comprises an insulation shell, wherein an isolation static contact, a straight-moving slide rail and a grounding contact are sequentially and fixedly arranged in the insulation shell along a straight direction, and a moving guide rod which is in slide fit with the straight-moving slide rail is arranged on the straight-moving slide rail; in a switch-on station, the front end of the moving guide rod is connected with the isolation static contact, and the rear end of the moving guide rod is connected with the straight-moving slide rail; in a switch-off state, the front end of the moving guide rod is separated from the isolation static contact; in a grounding state, the front end of the moving guide rod is connected with the straight-moving slide rail, and the rear end of the moving guide rod is connected with the grounding contact. The straight-moving type three-station isolation switch is small in size, simple in structure, and suitable for being used in a narrow space; an electric field is uniformly distributed around the moving guide rod; the straight-moving type three-station isolation switch is applied to a solid pole post, and the sealing of the solid pole post is facilitated due to a straight-moving structure; the straight-moving type three-station isolation switch is good in external insulativity, and safe and reliable to use because the outer surface of the insulation shell is touchable during a running process.
Description

Conventional three stations isolation, earthed switch are generally disconnecting link formula structures, and the rotation by a rotating shaft drives disconnecting link to rotate, thus connection, disconnection and the ground connection of realizing circuit.But this three-station overall dimension is larger, non-uniform electric, can not be used in the place of narrow space.
Summary of the invention
In view of this, the object of this invention is to provide a kind of direct-acting three-working-position isolation, to solve, the existing volume of existing disconnecting link formula tri-station isolating switch is large, Electric Field Distribution is uneven, can not be used in the problems such as narrow space.
Direct-acting three-working-position isolation of the present invention, comprises insulation shell, in described insulation shell, along rectilinear direction, is fixedly installed successively isolation fixed contact, directly moves slide rail and grounding contact, on described straight moving slide rail, is provided with the moving leader being slidably matched with it;
At combined floodgate station, the front end of described moving leader is connected with isolation fixed contact, and the rear end of described moving leader is connected with straight moving slide rail;
Under gate-dividing state, the front end of described moving leader is separated with isolation fixed contact;
Under ground state, the front end of described moving leader is connected with straight moving slide rail, and the rear end of described moving leader is connected with grounding contact.
Further, described straight moving slide rail is cylinder tube shape, described moving leader is slidably matched with the endoporus of straight moving slide rail, on described isolation fixed contact, be provided with the cylindrical hole coordinating with moving leader front end, on described grounding contact, be provided with the cylindrical hole coordinating with moving leader rear end, on the cylindrical hole hole wall of described isolation fixed contact, be provided with the first fingertip spring, on the front end inner hole wall of described straight moving slide rail, be provided with the second fingertip spring, on the rear end inner hole wall of described straight moving slide rail, be provided with the 3rd fingertip spring, on the cylindrical hole hole wall of described grounding contact, be provided with the 4th fingertip spring.
