Abstract
The utility model relates to a high voltage silicon rubber dry cable terminal. The utility model is characterized in that the back part is provided with a stress cone (2); the front end of the stress cone (2) is a horn-shaped conical surface (2a) which is embedded in the annular side wall of a silicon rubber insulation bushing (3) which a cable is sheathed in; the front port of the silicon rubber insulation bushing (3) is sealed with a sealed waterproof cap (4); the back of a conductive terminal (5) extends axially into the sealed waterproof cap (4), and the rear part of the conductive terminal (5) is provided with a wire core cavity (5a) which is communicated with an inner cavity of the silicon rubber insulating bushing (3); the outer wall of the silicon rubber insulating bushing (3) is provided axially with a plurality of sheds (3a) which encircle the central axis of the cable and protrude toward sides. The utility model has the advantages of simple structure, light weight, good insulation performance, safety and convenient installation and operation.
Description
Technical field
The utility model belongs to a kind of with high-tension cable is terminal when being connected with power consumption equipment required electric cable accessories, particularly is applicable to the high-tension cable of 66～110KV.
Background technology
When carrying out the cable connection, the core of cable must will exhume out, concerning the such high-tension cable of 66KV, 110KV, hv cable termination may cause electric stress to be concentrated because of the electric field distortion that high-tension electricity produces at the position of exhuming and cause electrical discharge, so must have reliable insulation property and electric field controls.Present domestic 66KV, 110KV cable termination all adopt the porcelain bushing type structure, and for example the porcelain bushing type cable termination of 110KV can be up to 1.5 meters, and be very heavy, and it is broken easily in transportation, be installation exercise aloft during installation, also will charge into iknsulating liquid in the insulator, labour intensity is very big, and can cause the insulator explosion when breaking down, surrounding devices, personnel component are threatened, the insulator long operational time, accumulate dust easily, also need to have a power failure and clean, work high above the ground also has certain danger.
Summary of the invention
It is light simple, easy for installation that the technical problems to be solved in the utility model order provides a kind of structure, the high pressure silicon rubber dry core cable terminal of security of operation.
The technical scheme that addresses the above problem is (referring to implementing illustration): the utility model rear portion is provided with the stress cone (2) with semiconductive material made of face contact sleeve on cable (1), stress cone inwall front port is the tubaeform conical surface (2a) that internal diameter enlarges forward, the tubaeform conical surface is imbedded in the annular sidewall that is enclosed within the outer silicon rubber insulation sleeve pipe (3) of cable, the insulating sleeve front port is equipped with the water-tight cap (4) that insulating material is made, conducting terminal (5) rear axle is to stretching into water-tight cap (4), the core chamber (5a) that the conducting terminal rear portion is provided with and insulating sleeve (3) lumen shaft are to being communicated with, and insulating sleeve outer wall axial distribution has the full skirt (3a) to the sidepiece protrusion of some annular sleeve central axis.
Using method of the present utility model is: cable core (1a) exhumes out the cable end piece front portion earlier, one section cable insulation (1b) exhumes out at the cable core rear portion, be inserted in the stress cone (2) and insulating sleeve (3) that is connected as a single entity, cable core (1a) is inserted in the core chamber (5a) of conducting terminal, make the cable outer shielding layer (1c) and the line of demarcation of cable insulation (1b) be positioned at the position of the tubaeform conical surface of stress cone, the cable outer shielding layer contacts electrical connection with the abundant face of stress cone, with specific purpose tool conducting terminal and the cable core that inserts in it are clamped then, the two abundant face contact is electrically connected, promptly install, conducting terminal is used for being electrically connected with power consumption equipment.The high voltage electric field distortion of cable end piece mainly occurs in the position, line of demarcation of cable outer shielding layer and cable insulation, the tubaeform conical surface (2a) of the stress cone made from semiconductive material of the utility model setting can make the Electric Field Distribution at this position be tending towards evenly satisfying the requirement of electrical strength; The full skirt (3a) of insulating sleeve outer wall axial distribution can prolong the creepage distance at conducting terminal (5) and rear portion, prevents electrion, and water-tight cap (4) can play the water-tight effect.
The utility model adopts silicon rubber insulation sleeve pipe and water-tight cap to strengthen the insulation of cable end piece and adopts stress cone to improve Electric Field Distribution, good insulation preformance, safe and reliable in the use, and it is simple in structure, in light weight, easy to install, needn't resemble the height that need note built-in electrical insulation liquid the porcelain bushing type terminal at any time, the cleaning that yet need not have a power failure in the running can not hinder for some reason the surrounding devices and the person are threatened.

Specific embodiments
The embodiment explanation
This routine stress cone 2 is to make of the semiconductive silastic material, insulating sleeve 3 electrically insulating silicone rubber material, and water-tight cap 4 is connected with insulating sleeve 3 tight fits, and conducting terminal 5 axially stretches into the water-tight cap, and is connected with the water-tight cap thread.
The tubaeform conical surface 2a at stress cone 2 inwall front port positions is the surfacess of revolution around the insulating sleeve central axis, and its rotation bus is to be the curve that the circular arc slyness of camber line that the slyness of an angle is connected and front end is formed by connecting by two sections with the insulating sleeve central axis.
Full skirt 3a and insulating sleeve on these routine insulating sleeve 3 outer walls are integral structures, and full skirt 3a axially small one and large one is staggered, this structure has improved the mechanical strength of full skirt on the one hand, has strengthened the anti-creepage effect of full skirt on the one hand.
