Abstract
The utility model relates to a high voltage and ultra-high voltage cable terminal accessory, in particular to a connection device of a cable terminal caudal tube and cable aluminum jacket. The utility model comprises a caudal tube(1) and a cable aluminum jacket(2); wherein the caudal tube(1) and the cable aluminum jacket(2) are connected through a copper woven belt(3) which is winded by metal wires(4); and the copper woven belt(3) is positioned in the caudal tube(1). The benefits of the utility model are that: 1. simple in structure and convenient to be connected; once a plunger ring presses first and then a bolt fastens the copper woven belt, the metal wire and copper woven belt are not needed to be winded, thus being very convenient; 2. having good water proof performance, which can prevent steam from entering the caudal tube from the tail of the caudal tube and enhances the grounding reliability, safety and stability of entire electric power cable connection system.
Description
Technical field
The utility model relates to a kind of high pressure, extra-high-tension cable terminal attachment, the jockey of particularly a kind of cable termination tail pipe and electrical cable aluminium sheath.
Background technology
At present, the high pressure of 66kV and the above electric pressure of 66kV, in the ultrahigh voltage power cable connected system, as the cable termination annex, must ground connection especially for the cable termination tail pipe of outdoor terminal and GIS terminal and electrical cable aluminium sheath, the cable termination tail pipe directly is connected with earth connection outward, and the ground connection of electrical cable aluminium sheath is by being connected with tail pipe, realize electrical cable aluminium sheath ground connection indirectly, because electrical cable aluminium sheath and the ground connection reliability that is directly connected to electrical cable aluminium sheath being connected of tail pipe, the stability that more is related to the cable connected system, therefore, electrical cable aluminium sheath is very important with being connected of tail pipe.The jockey of electrical cable aluminium sheath and tail pipe generally has two kinds of structures at present: first kind of structure (as shown in Figure 2), it comprises tail pipe 1, electrical cable aluminium sheath 2, the afterbody of tail pipe 1 and electrical cable aluminium sheath 2 interconnect by the affixed lead 7 of warding off, just ward off an end of lead 7 and the afterbody Joint of tail pipe 1, ward off plumbous 7 the other end and electrical cable aluminium sheath 2 Joints.The electrical cable aluminium sheath of this structure and the jockey of tail pipe exist following defective: with ward off plumbous with tail pipe afterbody and electrical cable aluminium sheath when affixed the operating procedure process very complicated, if and misoperation can cause the destruction to cable insulation, have influence on the performance of entire product, thereby make the reliability decrease of whole connected system; Second kind of structure (as shown in Figure 3), it comprises tail pipe 1, electrical cable aluminium sheath 2, the afterbody of tail pipe 1 is connected by the copper braid over braid 3 that is tied with wire 4 with electrical cable aluminium sheath 2, just an end of copper braid over braid 3 is connected with the afterbody of tail pipe 1, the other end of copper braid over braid 3 is connected with electrical cable aluminium sheath 2, is wrapped with wire 4 and firm welding then outside copper braid over braid 3.The electrical cable aluminium sheath of this structure exists following defective with the jockey of tail pipe: (1) is because the afterbody of tail pipe 1 is connected so attended operation trouble of getting up, inconvenience by the copper braid over braid 3 that is tied with wire 4 with electrical cable aluminium sheath 2; (2) the afterbody water resistance of tail pipe is poor, and steam can enter in the tail pipe along earth connection, thereby can have influence on the performance of product, and the ground connection reliability of whole power cable connected system is reduced.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of simple in structure, attended operation is convenient, the cable termination tail pipe of good waterproof performance and the jockey of electrical cable aluminium sheath.
Realize that the above-mentioned purpose technical scheme is: the jockey of a kind of cable termination tail pipe and electrical cable aluminium sheath, comprise tail pipe, electrical cable aluminium sheath, tail pipe is connected by being tied with copper braid over braid wiry with electrical cable aluminium sheath, is tied with the inside that copper braid over braid wiry is arranged on tail pipe.
Further, described copper braid over braid is fixed in the inside of tail pipe by pressure ring.
Further, described copper braid over braid is fixed in the inside of tail pipe by bolt by pressure ring.
After adopting technique scheme, have a lot of benefits: the utility model is to be connected and to improve innovation on the basis of prior art of this structure by being tied with copper braid over braid wiry at the afterbody of the tail pipe that generally adopts now and electrical cable aluminium sheath, improve the innovation part and be to change into and be tied with the inside that copper braid over braid wiry is arranged on tail pipe and be connected with electrical cable aluminium sheath, this makes the utility model: (1) is simple in structure, attended operation makes things convenient for.No longer need to twine wire and copper braid over braid, as long as compress the copper braid over braid and carry out affixed, very convenient with bolt etc. with pressure ring; (2) water resistance is good.Avoided steam to enter tail pipe inside by earth connection, water resistance is good, has improved ground connection reliability, fail safe, the stability of whole power cable connected system.

Fig. 2 wards off the structural representation of the jockey of plumbous stube cable terminal tail pipe and electrical cable aluminium sheath for available technology adopting;
Fig. 3 is the structural representation of the jockey of available technology adopting copper braid over braid stube cable terminal tail pipe and electrical cable aluminium sheath.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Embodiment one
As shown in Figure 1, the jockey of a kind of cable termination tail pipe and electrical cable aluminium sheath, comprise tail pipe 1, electrical cable aluminium sheath 2, copper braid over braid 3, wire 4, pressure ring 5, the copper braid over braid 3 outer wires 4 and affixed firm that are tied with, copper braid over braid 3 and wire 4 are arranged on the inside of tail pipe 1, tail pipe 1 is connected by copper braid over braid 3 with electrical cable aluminium sheath 2, one end of copper braid over braid 3 by pressure ring 5 by the bolt 6 affixed bosom step places that are pressed on tail pipe 1, the other end of copper braid over braid 3 is connected with electrical cable aluminium sheath 2, and wire 4 adopts tinned copper wire.
The utility model is not limited to the foregoing description, and the technical scheme that all employings are equal to replacement or equivalence replacement formation all belongs to the claimed scope of the utility model.
Operation principle of the present utility model is: tail pipe 1 is connected by the copper braid over braid 3 that is tied with wire 4 with electrical cable aluminium sheath 2, directly is connected with earth connection outside the tail pipe 1, thereby realizes the ground connection of electrical cable aluminium sheath 2 indirectly.
