Abstract
The utility model discloses a contact box used in a high-voltage switch cabinet. The contact box comprises a contact box body, wherein the contact box body is formed by epoxy resin through vacuum casting and is in a cylindrical shape, a static contact, an embedding element, a semiconductor shielding ring, a grounding lead wire, a copper voltage equalizing ring, a screw and a high-voltage lead wire are arranged in the contact box body, a through hole is arranged on the static contract, a round copper fixing seat is also arranged in the contact box body, an internal threaded hole is arranged on the fixing seat, the fixing seat is connected with the contact box body through the embedding element, and the static contact and the fixing seat are fixed by the screw through the threaded hole. Copper materials cast in the contact box are reduced, and the manufacture cost is favorably reduced. A high-voltage shielding layer and a low-voltage shielding layer are adopted and are matched so that the electric field between the high voltage and the low voltage is uniformly distributed in the epoxy resin, the service lives of the insulation materials are prolonged, complicated charged components such as movable contacts, static contacts inside the contact box are completely shielded, the tip electric field is reduced, and the local discharge level is improved.
Description
Technical field
The utility model relates to a kind of contact box, the contact box of using in particularly a kind of high-tension switch cabinet.
Background technology
Contact box is an epoxy resin APG operation pressure gel forming structure, is used for various handcart switch cabinets, plays insulation and isolates and connect transitional function.
Contact box plays in high-tension switch cabinet when fixed contact connects in the moving contact that can remove parts in the switch cubicle and the contact box and grounding shell insulate isolates and transitional function; Electrical insulation properties to guaranteeing switch cubicle has important effect, and the contact box of structure reasonable in design is controlled cost also more and more important to manufacturer in addition.
Existing cylinder formula contact box generally all be adopt with fixed contact and fixedly the holder of fixed contact be cast in the intrinsic mode of contact box.
The utility model content
The technical problem that the utility model will solve provides the contact box of using in a kind of high-tension switch cabinet.
For achieving the above object, the technical scheme of the utility model is following:
The contact box of using in a kind of high-tension switch cabinet; Comprise that epoxide resin vacuum burns the contact box body of annotating; Said contact box body is a cylindrical shape; Be provided with fixed contact, inserts, shield semiconductors circle, ground lead, copper grading ring, screw, high-voltage connection in the said contact box body, said fixed contact is provided with through hole; Also be provided with circular copper holder in the said contact box body, said holder is provided with internal thread hole, and said holder is connected with the contact box body through inserts, and said screw is fixed together fixed contact and holder through screwed hole.
Preferably, said ground lead makes the shield semiconductors circle reliably be connected ground connection with shell through inserts.
Preferably, said high-voltage connection links together copper grading ring and copper holder through inserts.
Preferably, said contact box body inside and outside wall entrance end is provided with waveform and climbs skirt.
Through technique scheme, the beneficial effect of the utility model is:
The mode that the copper holder that the utility model adopts fixing fixed contact and contact box are assembled mutually; This design has reduced the copper product that is cast in the contact box; Favourable reduction manufacturing cost; Convenient during simultaneously to copper busbar or fixed contact installation and maintenance or dismounting, do not processed or the influence of assembly error, can make dynamic/static contact remain the excellent contact state.
The utility model is cast in shielding ring in the contact box body; Make that electric field is evenly distributed in the epoxy resin between the high-low pressure; Increased the useful life of insulating material, the complicated live parts such as dynamic and static contact that contact box is inner shield fully, have reduced most advanced and sophisticated electric field and distortion electric field; Eliminate the atmospherical discharges in the contact box, improved the electrical insulation properties of local discharging level and switch cubicle.
Bus-bar room and the branch bar in the cable vault that the utility model can make switch cubicle when double separately with contact box in holder connect; Improved contact-making surface; Increase area of dissipation, effectively avoided present switch cubicle contact box commonly used that the branch bar of bus-bar room and cable vault is installed in double lumping together in the contact box and the fixed contact connection place higher relatively phenomenon of generating heat.
