Abstract
A silicon rubber prefabricated dry terminal comprises an insulating main body (1) and a stress cone (2), wherein the insulating body (1) and the stress cone (2) are integrally formed, and a plurality of large umbrella groups (3) and small umbrella groups (4) are alternatively arranged on the stress cone (2) of the cable terminal namely the outer layer of a high electric field. The product is an integrally prefabricated structure without field bonding, the quality hidden problems of coating a binder, which may be generated in the mounting process, are eliminated, the mounting quality of the product is improved, and the long-term operation quality of the products is ensured.
Description
Technical field
The utility model relates to cable termination, and especially a kind of integrated molding, nothing be the dry outdoor terminal of matched moulds seam vertically, specifically the full pre-fabricated dry terminal of a kind of silicon rubber.
Background technology
Silicon rubber prefabrication type cable termination at first is applied to the 10-35KV cable, along with the in the world progress of silastic material scientific research, present German WACKEK company, U.S. GE company, Dow corning company has all successfully released novel, the silicon rubber of high-quality, especially special fluid silicon rubber (has extraordinary anti-electric leakage gas trace ability, simultaneously can keep good mechanical and physical performance again), the in addition update of relevant special silicone rubber material processing plant, for silicon rubber prefabrication type cable termination for 110KV so that more the voltage levels crosslinked cable provide the foundation.
Over nearly 10 years, all represent enterprise abroad silicon rubber prefabrication type cable termination is applied to the 110KV electric pressure, they have represented the developing direction of cross-linked polyethylene insulated cable terminal.
The power cable dry outdoor terminal is cable line two ends and the device that other electric equipments are connected, and is that structure is the most complicated in the cable line, the parts that technology content is the highest; Also be the weak link in the cable line, the primary structure of 110KV silicon rubber prefabrication type cable termination product has following several both at home and abroad at present:
A, product are processed into more than 10 sections, adopt the binding agent scene that each section goods are set in together, and make the product bonding as a whole.The electric cable accessories producer in early stage more Europe makes this infrastructure product, and also there is this product of indivedual manufacturer production in China.
B, product are processed into 3 sections, and be on-the-spot with 3 sections product suits.
Though the application of above-mentioned two kinds of high-voltage products has obtained some successful experiences, need the scene bonding during owing to installation, and on-the-spot bonding a lot of uncertain factors that have easily produce some hidden danger of quality.
Summary of the invention
The purpose of this utility model is to be generally segmental structure for the integral prefabricated cable termination of existing silicon rubber, exist installation loaded down with trivial details, the bonded part is in the problem of the long-term hidden danger of quality such as easily aging fracture in service, propose the full pre-fabricated dry terminal of a kind of silicon rubber, it not only has good electric property, and easy for installation, without burning, explosion hazard, moving non-maintainingly, also have very high mechanical strength and high leakproofness, is a kind of safe and reliable electric cable fitting.
The technical solution of the utility model is:
The full pre-fabricated dry terminal of a kind of silicon rubber, it comprises insulating body and stress cone, described insulating body and stress cone global formation.
In the utility model, the stress cone of cable termination is that the skin of high electric field region arranges several cluster parachutes.
In the utility model, the stress cone of cable termination is that the skin of high electric field region arranges several large cluster parachutes and little cluster parachute.
In the utility model, the outer field large cluster parachute of the high electric field region of cable termination and umbellule flock-mate are for arranging.
In the utility model, the insulating body skin of cable termination arranges several large cluster parachutes and little cluster parachute.
In the utility model, the insulating body skin of cable termination is arranged alternately several large cluster parachutes and little cluster parachute.
The beneficial effects of the utility model:
The integral prefabricated cable termination of silicon rubber of the present utility model solves above-mentioned these key issues effectively, has greatly improved the security reliability in the product running.
Product of the present utility model is integral prefabricated structure, does not need on-the-spot bonding, has eliminated installation process and has smeared the hidden danger of quality that adhesive may exist, and has improved the installation quality of product, has guaranteed product long-time running quality.
The integral prefabricated exterior of terminal of silicon rubber of the present utility model has been eliminated the impact that matched moulds seam place may produce defective in the rubber product manufacture process without vertical matched moulds seam, has improved the expection service life of product.
Silastic terminal surface field intensity highest region of the present utility model territory adopts big or small cluster parachute alternately to hide, and has reduced terminal end surface electric field strength, has improved product reliability of operation steady in a long-term.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, the full pre-fabricated dry terminal of a kind of silicon rubber, it comprises insulating body 1 and stress cone 2, and described insulating body 1 and stress cone 2 global formations are that the skin of high electric field region is arranged alternately several large cluster parachute 3 and umbellule groups 4 at the stress cone 2 of cable termination.
In the utility model, insulating body 1 skin of cable termination is arranged alternately several large cluster parachute 3 and umbellule groups 4.
The design concept of full pre-fabricated dry terminal of the present utility model is to take full advantage of the requirements that the silastic material characteristic realizes the terminal insulation system; Stress cone is inlaid in control terminal electric field in the insulator, guarantees excellent electrical properties, obtains insulator interface pressure with the high strength of silastic material, with the high resiliency of material, interface performance was stable when low residual deformation was guaranteed the cable operation; Anti-pollution, resistance to ag(e)ing with the silicon rubber excellence make terminal energy long-term safety reliability service.
The full prefabricated terminal of silicon rubber of the present utility model is lightweight, parts are few, easy for installation, flexible anti-shock and without burning, explosion hazard, moves non-maintainingly, is specially adapted to multiloop steel tube tower, bustling block, multi-channel parallel, breakdown repair.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
