Description
Technical field
The utility model is related to transmission line of electricity facility field, more particularly to a kind of 252kV cable terminal structures.
Background technology
At this stage, city net middle high-pressure is given in the continuous improvement of inner city urbanization degree and the continuous growth of power load
Line cord brings wide application prospect, has also necessarily promoted the fast of this new-type outlet method of substation with cable outlets
Cable run ratio is constantly raised in speed development, power network.Cable outlet has following outstanding advantages compared with overhead outlet:1. electricity
Cable is laid in underground, is difficult to be influenceed by natural meteorological condition and surrounding environment, and power transmission reliability is high；2. underground laying is not take up
Ground space, and same subway can many telegram in reply cables；3. underground mode is to personal safer, maintenance expense
With less.Therefore occupation of land face is required in densely populated place, integrated mill, power plant, congested traffic area, power network zone of intersection etc.
Product is small, safe and reliable, reduction power network generally all selects cable outlet side in the case of being influenceed for communications and transportation and urban construction
Formula.But there is cumbersome, the reason such as fluctuation of service of installation in traditional cable termination assembling.
The content of the invention
There is provided a kind of 252kV electricity simple in construction, dependable performance in order to make up the defect of prior art for the utility model
Cable terminal structure.
The utility model is achieved by the following technical solution：
The leading body of L-type is provided with a kind of 252kV cable terminal structures, including terminal shell, the terminal shell, it is described
The side connecting insulator of terminal shell, opposite side connection cable connect-disconnect plug, it is characterized in that, one end of the leading body and insulation
Shading ring is connected between son, the other end connection contact base of the leading body, the cable plug head connects hollow conductor, institute
State and guide rod is inserted with conductor, the guide rod is connected with leading body, spring touch finger, the spring touch finger are cased with outside the conductor
In contact base.
The cable plug head is 470mm cable plug heads.
It is bolted between the terminal shell and insulator.
The beneficial effects of the utility model are：
The utility model optimizes interior arrangement structure, cable termination inner space is obtained sufficiently effective utilization, subtracts
Small unnecessary space, the structure compared with other structures, with resistance is small, temperature rise is low, simple in construction, good appearance, cost it is low,
The advantages of safe and reliable, strong applicability, with high cost performance, extensively using and urban distribution network, industrial and mining enterprises, petroleum refining
Deng in field.
Brief description of the drawings
The utility model is further described below in conjunction with the accompanying drawings：
Fig. 1 is cross section structure diagram of the present utility model.
In figure, 1 terminal shell, 2 bolts, 3 insulators, 4 adsorbents, 5 cable plug heads, 6 leading bodies, 7 shading rings, 8 touch
Headstock, 9 conductors, 10 guide rods, 11 spring touch fingers.
Embodiment
Accompanying drawing is specific embodiment of the utility model.As shown in figure 1, this kind of 252kV cable terminal structure, including terminal
Housing 1, the side of terminal shell 1 is by the connecting insulator 3 of bolt 2, and the side inner face relative with insulator 3 is provided with adsorbent 4,
The opposite side connection 470mm cable plugs first 5 of terminal shell 1, are provided with the leading body 6 of L-type, leading body 6 in terminal shell 1
One end and insulator 3 between connected by shading ring 7, the other end of leading body 6 connection contact base 8, contact base 8 is recessed
Type, cable plug first 5 is connected with one end of conductor 9, and the other end of conductor 9 is the recessed hollow structure in end, and end insertion is touched
In headstock 8, guide rod 10 is inserted with the hollow structure of conductor 9, the other end of guide rod 10 is connected with leading body 6, the overcoat of conductor 9
There is spring touch finger 11, spring touch finger 11 is located in contact base 8.
In the utility model, conductor 9 is in contact by spring touch finger 11 with contact base 8, forms galvanic circle, guide rod
10 certralizing abilities may insure that conductor 9 is located at the center of contact base 8, it is ensured that the contact between spring touch finger 11 and contact base 8
Area, plays a part of reducing contact resistance, enhancing connection reliability.The afterbody of leading body 6 passes through the fixed conductor 9 of bolt 2, conductor
9 unique texture can effectively be homogenized field strength distribution inside cable, and cable plug first 5 is connected on conductor 9, can by cable
To realize the conveying of electric energy.
In addition to technical characteristic described in specification, remaining technical characteristic is technology known to those skilled in the art.
