Abstract
The utility model relates to a terminal accessory for high temperature superconducting cables, which comprises a stress cone and an insulator, wherein the stress cone and the insulator form a whole through injection. Through holes with equal diameter are arranged in the stress cone and the insulator; the periphery of the insulator is outwards distributed at intervals with increase climbing umbrella skirts. Because the stress cone and the insulator are made into a whole, the utility model has the advantages of simpler structure, convenient site construction and reliable electric performance.
Description
Technical field
The utility model relates to the power cable terminal annex, particularly a kind of terminal attachment that is used for the high-temperature superconductive cable of 35kV and following electric pressure.
Background technology
The hts power cable termination annex is the important component part in the high-temperature superconductive cable structure, it is interconnective port between high-temperature superconductive cable and outside other electric equipments (for example thermostat etc.), also be the connectivity port of cable coolant and refrigeration plant, undertaking the transition of temperature and electromotive force.Because consider the coordinated of above each system, traditional thermal shrinkage type cable termination and prefabricated cable terminal attachment can't satisfy.Must adopt the mode of shrinkage could satisfy installation and instructions for use.This product still belongs to blank at home and abroad at present, must be made by cases of otherwise standard design.
The utility model content
The technical problems to be solved in the utility model is, provides a kind of stress cone and insulator hts power cable termination annex integrated, easy to use, that overall performance electrical performance is stable.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of hts power cable termination annex is provided, comprise by annotating stress cone and the insulator that rubber forms an integral body, and described stress cone and insulator inside are provided with isodiametric through hole; The periphery of described insulator outwards spaced apart increasing is climbed full skirt.
Be provided with the stay pipe that struts described stress cone and insulator in the described through hole of above-mentioned hts power cable termination annex.
The described stress cone of above-mentioned hts power cable termination annex forms for the semiconductive silicon rubber vulcanization; Described insulator is for to be formed by the iknsulating liquid silicon rubber vulcanization.
The internal diameter of the described through hole of above-mentioned hts power cable termination annex before expansion is 75mm, and after inserting described stay pipe, the stay pipe internal diameter is 135mm.
Compared with prior art, hts power cable termination annex of the present utility model is made one with stress cone and insulator, makes its structure more simple, and site operation is convenient, and is quick, the trouble of having avoided traditional pyrocondensation electric cable accessories to get angry and heat.
Description of drawings
Fig. 1 is the cross-sectional schematic before the expansion of the utility model hts power cable termination annex.
Fig. 2 is the cross-sectional schematic after the expansion of the utility model hts power cable termination annex.
Embodiment
Below in conjunction with accompanying drawing hts power cable termination annex of the present utility model is described in further detail.
As shown in Figure 1 and Figure 2, hts power cable termination annex of the present utility model comprises stress cone 1 and insulator 3.Described stress cone 1 forms an integral body with described insulator 3 by annotating rubber, and its inside is provided with isodiametric through hole 5.
When making, make stress cone 1 with semiconductive silicon rubber earlier, then stress cone 1 is placed in the mould, cast liquid Silicon-On-Insulator glue forms insulator 3, then together with stress cone 1, the general injection sulfidization molding, thus obtain the hts power cable termination annex of one.
The periphery of described insulator 3 outwards spaced apart increasing is climbed full skirt 7, thereby has increased creepage distance, improves insulation effect, improves fail safe.
The internal diameter of described through hole 5 before expansion is 75mm, and after inserting described stay pipe 9, stay pipe 9 internal diameters are 135mm.In use, in described through hole 5, be provided with and strut the stay pipe 9 of described stress cone 1 and insulator 3, thereby make the hts power cable termination annex to arrive the installation site smoothly by the outstanding position of cable.Because the external diameter of hyperconductive cable reaches 100mm, behind the taking-up stay pipe 9, under the effect of caoutchouc elasticity, the through hole 5 of described hts power cable termination annex shrinks, to guarantee the radial compaction power of terminal attachment to hyperconductive cable.
Claims (4)
