Abstract
The utility model discloses a plug-in type indoor-outdoor terminal for a high-voltage power cable, which is composed of a wire-out rod (1), an insulating main body (2), a stress cone (6), a cone support (7), a base flange (8), a support insulator (11), a tail pipe (12) and an earthing fitting (15). The terminal is connected with the cable in the plug-in way. A main body of the terminal is composed of a conductive rod, resin and high molecular rubber compounded into an integral structure. The integral dry type base-shaped terminal with compact structure needs no pouring agent in the course of installation and use. The main body of the terminal in a special shape has small volume and light weight.
Description
Technical field
The utility model relates to a kind of high voltage power cable user internal and external terminals, particularly relates to a kind of indoor outer terminal of high voltage power cable of can plug-in installing.
Technical background
Along with the development of China's power construction, the continuous of electricity needs risen, and the demand of high voltage power cable increases day by day, and the HV cable accessories product is being extensive use of, and the HV cable accessories product domesticizes, seriation.The high voltage power cable terminal of extensive use in the market has bushing type and complete two kinds of frame modes of pre-fabricated dry.
The cable length that the bushing type terminal needs to handle in installation process is greater than the nearly 1.2m of the treated length of 1.5m, outer semiconducting layer; Need in sleeve pipe, to water dielectric at the construction field (site), need fastening high-voltage terminal end seal and radome cap after filling is good; Installation is complicated, the engineering time is long, and the factor that product quality is influenced by installation process is more; And when the dielectric in the sleeve pipe leaks, easily have an accident, and environment is polluted; The explosion-proof performance of insulator is poor, hurts sb.'s feelings easily during the terminal accident and damage equipment.
Full pre-fabricated dry terminal is compared with the bushing type terminal, in light weight, need not in terminal, water dielectric, explosion-proof performance is good, but the cable length that still needs to handle in installation process is greater than the nearly 1.2m of the treated length of 1.5m, outer semiconducting layer, and the engineering time is long.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple installation, good, the leak free high voltage power cable of the explosion-proof performance indoor outer terminal of plug-in.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of high voltage power cable indoor outer terminal of plug-in, it is characterized in that: at the preceding high-voltage terminal bar as a whole (1) that is provided with of insulating body (2), in described insulating body (2), be provided with and the coaxial metal insert that is connected of described high-voltage terminal bar (1) (4), in described metal insert (4), be provided with plug gold utensil (3), in described insulating body (2), be provided with stress cone (6) and the stop cover (5) thereof corresponding with described plug gold utensil (3), and the awl holder (7) that acts on described stress cone (6), be provided with base flange (8) and supporting insulator (11) in the bottom of described insulating body (2), tightening up screw rod (9) is connected tail pipe (12) on the base flange (8), between the flange (10) of described tail pipe (12) and described awl holder (7), be provided with spring (17), in described tail pipe (12), be provided with O-ring seal (13) and gland (14) thereof, on described tail pipe (12), be provided with ground connection gold utensil (15).
Described insulating body (2) is composited by resin, insulating polymeric material, and profile adopts big or small umbrella skirt construction, and is tapered.
Adopt the high voltage power cable indoor outer terminal of plug-in of technique scheme, by outlet bar, insulating body, plug gold utensil, metal insert, stop cover, stress cone, awl holder, base flange, tighten up screw rod, supporting insulator, tail pipe, ground connection gold utensil etc. and form, insulating body is composited by resin, insulating polymeric material, be dry construction, need do not pour into a mould any dielectric in installation, the use; Profile adopts big or small umbrella skirt construction, and is tapered, has good anti-pollution flashover characteristic, can be used for the filthy area of level Four; High-voltage terminal bar and insulating body are an integral body, compact conformation; The inner connection mode of cable core and terminal is a plug-in; Cable core becomes an integral body with the plug gold utensil by crimping, directly inserts terminal inner cable passage; The electric stress control mode is: geometric type, adopt stress cone; Stress cone adopts polymer rubber pressure to annotate the rubber shaping, and the stress cone hold down gag presses closer stress cone on the insulating body tapered wall by the flange and the spring of tail pipe; Tail pipe and cable jacket be connected to press seal type.Compare with the high voltage power cable terminal of the two kinds of structures in front, this product is that a kind of installation is easier, explosion-proof performance is good, leak free high voltage power cable terminal.It has following characteristics:
1, product design is tapered, has attractive appearance, novelty;
2, in the installation process, the treated length of cable only is 1/6 of a bushing type terminal; Engineering time is short; With the connected mode of cable be: plug-in, install very easy;
3, entire product is the dry type structure, does not add any casting insulated medium, thus stopped the accident that terminal causes because of related causes such as leakages in running, and environmentally safe;
4, have good explosion-proof performance, damage people or equipment take place in the Shi Buhui that meets accident;
5, the connected mode of tail pipe and protective coverings of cable is a press seal type, and is easy for installation, be easy to safeguard.
In sum, the utility model is that a kind of simple installation, explosion-proof performance are good, nothing is leaked and the high voltage power cable indoor outer terminal of plug-in simple in structure, easily manufactured, dependable performance.
