Abstract
Provided is a contact box for a high voltage switch cabinet, comprising a cylindrical insulator with one end having an opening while the other end being sealed, wherein the rim of the opening circumferentially protrudes outward to form an installing flange; and the installing surface of the installing flange is provided with multiple screw inserts. The contact box of the utility model is characterized in that all the screw inserts are arranged in a convex column higher than the installing surface; the periphery of the convex column is provided with a cover cap; and the central part of the cover cap is provided with a receiving through hole. While the contact box is used, the cabinet installing plate is clamped upon the convex column in a close-fitting manner via the corresponding through hole. Then a bolt is used for fixing the cover cap. The lower ring surface of the cover cap is tightly pressed to the concaved portion of the cabinet installing plate. The cabinet body installing plate is reliably fixed via the horizontal positioning of the convex column as well as the vertical and horizontal positioning of the cover cap, thereby effectively avoiding the offset discharging, uneven electric field, and the similar problems and ensuring the reliable, secure and stable operation of the high voltage switch cabinet.
Description
Technical field
The utility model relates to a kind of contact box for high-voltage switchgear, especially belongs to a kind of CTH6-12 contact box.
Background technology
Have the structure of contact box for high-voltage switchgear now, comprise the insulator of a tubular, the sealing of the one end opening other end is by epoxy compound integral cast moulding.Form a mounting flange after all convexes of the peristoma of described opening.Being provided with shirt rim, inner chamber roof place on the wall of cylindrical body is provided with fixed contact inserts is installed, a relative cylindrical body roof place radially side has a groove, it is the busbar line outlet that this groove is used for admitting busbar, during installation, busbar stretches into the cylindrical body inner chamber by groove and fixed contact is linked together, and the circuit breaker acting arm stretches into inner chamber from described opening and connects fixed contact.The contact box of this structure is when reality is used, when especially using under current state, there are the following problems: the screw inserts and the installed surface that are arranged on mounting flange four angles are in same plane, only located fixing between cabinet mounting panel and contact box by set bolt, easily occur loosening, thereby the phenomenons such as skew is discharged, electric field is inhomogeneous occur, not only affect contact box useful life, go back the safety and stability reliability service of entail dangers to high-tension switch cabinet when serious.
Summary of the invention
The problems referred to above that exist for solving prior art, the utility model aims to provide a kind of contact box for high-voltage switchgear, this contact box is particluarly suitable for using under current state, has the cabinet mounting panel fixing reliable, the generation of the phenomenon such as discharge, electric field be inhomogeneous be can effectively stop to be offset, and then safe, stable, the reliability service of high-tension switch cabinet guaranteed.
For achieving the above object, the utility model has adopted following technical scheme: the structure of this contact box for high-voltage switchgear comprises a tubular insulator of end opening other end sealing; Form a mounting flange after all convexes of the peristoma of described opening, have a plurality of screw inserts on the installed surface of this mounting flange, it is characterized in that: described these screw inserts all are arranged in the convex post that protrudes from described installed surface, described convex post outer is arranged with a cover cap, and the middle part of this cover cap has one and admits through hole.
During as preferred concrete enforcement, the aperture of described admittance through hole is slightly larger than the screw aperture of described screw inserts.
During as preferred concrete enforcement, described convex post and screw inserts thereof and described insulator are the resin integral casting molded part.
During as preferred concrete enforcement, the bottom face of described cover cap is concavo-convex profile of tooth.
beneficial effect: compared with prior art, the utility model is placed in the screw inserts in the convex post, and after each convex post peripheral split type arranges a cover cap, when practical application, at first, the cabinet mounting panel is by corresponding through hole, the close-fit holding is on the convex post, then with the fixing cover cap of bolt, the lower anchor ring of cover cap is pressed on the spill position of cabinet mounting panel, horizontal location by the convex post, cover cap vertically to level to the location, the cabinet mounting panel has been obtained fixing very reliably, thereby effectively stopped the skew discharge, the generation of the phenomenons such as electric field is inhomogeneous, in addition, this structure has also strengthened the dielectric strength between contact box, cabinet mounting panel and circuit breaker contact arm, and then guarantees the safety and stability reliability service of high-tension switch cabinet.
For deepening understanding of the present utility model, be described in further detail by embodiment below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the left TV structure schematic diagram of an embodiment of the utility model.
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
In figure: insulator 1, outer skirt 11, busbar line outlet 12, inner chamber 2, mounting flange 3, screw inserts 31, convex post 32, cover cap 4, fixed contact is installed inserts 5, fixed contact fixing threaded hole 51, right-hand member 6.
Embodiment
Referring to Fig. 1, Fig. 2.Whole observation, the structure of this practical embodiment comprises an end opening other end sealing, that is: the left side opening right-hand member 6 tubular insulators 1 of sealing.Form a mounting flange 3 after all convexes of the peristoma of left side opening, the shape of mounting flange 3 is generally square.Have a plurality of screw inserts 31 on the installed surface of this mounting flange 3, these screw inserts 31 generally are arranged on four jiaos of square mounting flange 3.As innovation place of the present utility model: described these screw inserts 31 all are arranged in the convex post 32 that protrudes from described installed surface, described convex post 32 outer is arranged with a split type cover cap 4, the middle part of this cover cap 4 has one and admits through hole, namely is used for admitting set bolt.
During concrete enforcement:
At first, described convex post 32 can be Split assembled spare with insulator 1, but resin integral casting molded part preferably forms convex post 32, metal screw inserts 31 and insulator 1 firmly whole.
Secondly, the aperture of described admittance through hole can be slightly larger than the screw aperture of described screw inserts 31.Under this structure, pad can be placed on during use between the nut fastening surface and cover cap 4 top end faces of bolt, thereby increase is to the fastening stress surface of cover cap 4.
At last, for preventing cabinet mounting panel horizontal shift (in Fig. 2 for vertically to), on the fastening surface of the relative cover cap 4 of cabinet mounting panel, corresponding spill position is set, locating effect is better.Another kind of scheme is that the bottom face with described cover cap 4 is designed to concavo-convex profile of tooth, and on the fastening surface of the relative cover cap 4 of described cabinet mounting panel, corresponding caulking groove is set, and to increase locating effect, prevents the displacement of cabinet mounting panel.
Above-described embodiment only is used for mentality of designing of the present utility model is described, and should not be considered as structure qualification of the present utility model, and is any under the utility model mentality of designing inspires and the distressed structure of making all should be subject to the protection of this patent.
