Description
Technical field
The utility model is related to cable machinery field, more particularly to a kind of cable termination annex.
Background technology
Through investigation statisticses, had reached 99 hours because of cable termination operation troubles power off time within 2014, due to failure frequency
Send out, power off time is long, directly influence electricity sales amount, the good service level of east victory power supply branch office, therefore, reduction cable termination event
Barrier rate is particularly significant to east victory power supply branch office.According to on-site investigation situation, find the main crux of cable fault in 2014 at end
Termination failure, 2 aspects of transition joint failure, and terminal fault accounting is huge.Dissected and found by the cable to failure：Terminal
The trouble point of head is concentrated at the semi-conductive layer rings cut of cable termination.Annual cable termination failure is 12 times within 2014, and electricity
Cable failure is at the semi-conductive layer rings cut of cable termination.The problem is major safety risks, technological means is taken, by the hidden danger
Eliminate, 12 failures can largely be avoided, the reason for finding cable terminal Frequent Troubles through further investigation is due to ring
Cut place and occur field strength distortion, non-uniform electric, and make partly to lead because gravity is penetrated into cable end semi-conductive layer due to silicone grease cream
It can not effectively be overlapped with copper shield, cause failure, therefore, a kind of cable termination annex of invention has very much to solve the above problems must
Will.
Utility model content
The purpose of this utility model is to provide a kind of cable termination annex, with asking for solving to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：A kind of cable termination annex, including main body,
The body top is provided with copper shield, and the copper shield outer wall is provided with the first winding ring, the first winding ring and copper shield ring
Around connection, semi-conductive layer is provided with the top of the copper shield, the semi-conductive layer outer wall is provided with the second winding ring, second winding
Ring, around being connected, is provided with the top of major insulation bar, the major insulation bar at the top of the semi-conductive layer with semi-conductive layer and is provided with conductor, institute
State and conductor cap is provided with outside conductor, the conductor cap is flexibly connected with conductor.
It is preferred that, the first winding ring is made with the second winding ring by tinned copper wire material, and is connected with each other.
It is preferred that, the first winding ring is with the second winding ring winding direction on the contrary, and the winding number of turns is certain.
Technique effect of the present utility model and advantage：Copper wire is wound at rings cut, induced-current is exported by copper wire,
And semi-conductive tape is wound, the tongue of formation can also prevent silicone grease cream from flowing down.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is partial structural diagram of the present utility model.
In figure：1 main body, 2 copper shields, 3 first winding rings, 4 semi-conductive layers, 5 second winding rings, 6 major insulation bars, 7 conductors,
8 conductor caps.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
The utility model provides a kind of cable termination annex as shown in Figure 1-2, including main body 1, the top of main body 1
Provided with copper shield 2, the outer wall of copper shield 2 is provided with the first winding ring 3, and the first winding ring 3 is surround with copper shield 2 to be connected,
The top of copper shield 2 is provided with semi-conductive layer 4, and the outer wall of semi-conductive layer 4 is provided with the second winding ring 5, the second winding ring 5
With semi-conductive layer 4 around being connected, the top of semi-conductive layer 4 is provided with major insulation bar 6, and the top of major insulation bar 6 is provided with conductor
7, the outside of conductor 7 is provided with conductor cap 8, and the conductor cap 8 is flexibly connected with conductor 7.
First winding ring 3 is made with the second winding ring 5 by tinned copper wire material, and is connected with each other, the first winding ring 3
With the second winding winding direction of ring 5 on the contrary, and the winding number of turns is certain, so will phase as the direction of an electric field produced by copper wire magnetic field
Instead, both, which are cancelled each other, to be impacted to the Electric Field Distribution of cable, and semi-conductive layer is wrapped up on copper wire, is formed by copper cash
Raised ring-type result, can prevent the downslide of silicone grease cream.
Operation principle：Anti-tracking copper wire annex is made, copper wire is wound at rings cut, induced-current is led by copper wire
Go out, and wind semi-conductive tape, the tongue of formation can also prevent silicone grease cream from flowing down, and winding in copper wire, winding process to ensure
The directions of two winding rings are reverse, and the number of turns is certain, so as the direction of an electric field produced by copper wire magnetic field will on the contrary, both
Cancelling each other will not impact to the Electric Field Distribution of cable, be that semi-conductive layer is wrapped up on copper wire, the projection formed by copper cash
Ring-type result, can prevent the downslide of silicone grease cream.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, this is not limited to
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical scheme described in foregoing embodiments, or to which part technical characteristic
Equivalent substitution is carried out, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvements made etc.,
It should be included within protection domain of the present utility model.
