Abstract
A cable terminal being processed by high voltage air gap shielding is prepared as pouring umbrella skirt on line out column and epoxy sleeve, embedding high voltage shielding end in epoxy sleeve, connecting said shielding end to internally embedded metal sleeve, setting high voltage shielding cover at bottom connection position of said metal sleeve and line out column, arranging a semiconductor shielding layer between line out column and umbrella skirt, setting armour clamp in internally embedded metal sleeve and connecting said clamp with said metal sleeve by spring bolt.
Description
Technical field
The present invention relates to a kind of cable termination of high-voltage air-gap screened processing.
Background technology
Insulating material is in electric field, and partial discharge takes place easily for the impurity in the material, bubble etc.Partial discharge can cause that the electricity of insulating material is aging, produces electric branch, along with the aging development of electricity, can make the insulation property variation of material even lose insulation.In the electric cable accessories terminal, it is aging to eliminate electricity, considers from two aspects: the one, and the defective of material itself is as having impurity, bubble etc. in the material; The 2nd, structure Design, inevitably there is air in the junction of parts.
Summary of the invention
The objective of the invention is to effectively solve the partial discharge and electric the wearing out of terminal, solve traditional insert structure, a kind of cable termination of high-voltage air-gap screened processing is provided in stroke loose problem of bearing cable deadweight bolt in long-time running on the tower bar.
To achieve these goals, the technical solution used in the present invention is: a kind of cable termination of high-voltage air-gap screened processing, include external insulation by the injection molding full skirt of silicon rubber, the outlet bar, semiconductive shielding layer, the high-tension shielding cover, the high-tension shielding end, the embedded metal cover, epoxy bushing, insert gold utensil, full skirt is cast on outlet bar and the epoxy bushing, be inlaid with the high-tension shielding end in the epoxy bushing, the high-tension shielding end is connected with the embedded metal cover, the embedded metal cover has the high-tension shielding cover with the junction, bottom of outlet bar, one deck semiconductive shielding layer is arranged between outlet bar and full skirt, semiconductive shielding layer extends in the high-tension shielding end, in the embedded metal cover insertion gold utensil is arranged, insert gold utensil and connect by spring bolt with the embedded metal cover.
The present invention has the following advantages compared with the prior art: one, and the junction between the high-voltage part is effectively shielded, and the junction air gap is in the low field intensity zone, has eliminated partial discharge.The anti-electric ageing properties of product is improved greatly.Two, insert gold utensil and adopt the locked structure of insertion, this structural-mechanical property excellence.Can not cause cable to come off because of the loosening of bolt.Three, the silicon rubber full skirt pours into an integrated entity with epoxy bushing, outlet bar, follows the structure that full skirt is inserted in epoxy bushing, outlet bar to compare, and interface performance is good, has improved the creep resistance energy at interface.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present invention.
Embodiment:
Shown in accompanying drawing 1, present embodiment comprises that external insulation is by the injection molding full skirt 1 of silicon rubber, outlet bar 2, semiconductive shielding layer 3, high-tension shielding cover 4, high-tension shielding end 5, embedded metal cover 6, epoxy bushing 7, insert gold utensil 8, full skirt 1 is cast on outlet bar 2 and the epoxy bushing 7, be inlaid with high-tension shielding end 5 in the epoxy bushing 7, high-tension shielding end 5 is connected with embedded metal cover 6, embedded metal cover 6 has high-tension shielding cover 4 with the junction, bottom of outlet bar 2, one deck semiconductive shielding layer 3 is arranged between outlet bar 2 and full skirt, semiconductive shielding layer 3 extends in the high-tension shielding end 5, in the embedded metal cover 6 gold utensil 8 of insertion is arranged, insert gold utensil 8 and connect by spring bolt, be the structure that is automatically locked after inserting with embedded metal cover 6.Described full skirt 1 adopts big or small umbrella skirt construction, and outlet bar 2 place's full skirts are tubular, and epoxy bushing 7 places' full skirts adopt taper, have both saved material, guaranteed performance, and form is attractive in appearance, novel.Outlet bar 2 air gaps have carried out shielding processing, have reduced partial discharge; Insert the syndeton of gold utensil 8, guaranteed through-current capability and born very big pulling force.
When plant produced, outlet bar 2 is connected with embedded metal cover 6 usefulness bolts, afterwards high-tension shielding cover 4 is inserted in from outlet bar 2, and high-tension shielding cover 4 is fixed on the embedded metal cover 6 with bolt, after bar 2 cleaning surfaces will occurring and drying, shield semiconductors layer 3 is inserted in outlet bar 2, then, puts into cast silicon rubber full skirt 1 in the mould.When product was installed at the scene, the cable that crimping is good was inserted into and inserts gold utensil 8, and cable core is realized connecting by locked.
