Abstract
The utility model discloses a high voltage power cable protection tube, including the body that divide into two parts, body upper portion is used for passing through of cable, and the lower part is crescent, is separated by one section circular arc with upper portion, the inside one deck conducting layer that is equipped with in upper portion of above -mentioned body, the cotton that absorbs water is packed to the lower part of body, simultaneously, is equipped with big through -hole between upper portion and the lower part, and this big through -hole can feed through body exterior space, and in addition still is equipped with the little through -hole of one or more, and the both sides of big through -hole are located to little through -hole branch, all feed through body upper portion and body lower part. The utility model provides a high voltage power cable protection tube, has effect waterproof and the shielding electric field, has stopped the potential safety hazard of cable in the transmission course, has reduced the maintenance cost in later stage.
Description
Technical field
The utility model relates to a kind of high voltage power cable protection tube.
Background technology
When cable is placed in buried in protection tube, due to the connection problem between the difference of geological conditions or protection tube, cable there will be steam seepage and forms dewdrop, and also can produce electric field around cable and concentrate, and easily concentrates electric discharge; Above-mentioned phenomenon is all unfavorable for the transmission of cable arrangement and signal, has buried potential safety hazard, has substantially increased the maintenance cost in later stage.
Utility model content
For solving the problems of the technologies described above, a kind of high voltage power cable protection tube provided by the utility model, has the effect of waterproof and electric field shielding, has stopped the potential safety hazard of cable in transmitting procedure, has reduced the maintenance cost in later stage.
A kind of high voltage power cable protection tube, comprising:
Body, this body is divided into two parts, and top is used for passing through of cable, and bottom is crescent shape, is separated by one section of circular arc with top;
The upper interior portion of above-mentioned body is provided with one deck conductive layer, the under-filled of body has absorbent wool, simultaneously, large through-hole is provided with between top and bottom, this large through-hole can be communicated with body exterior space, in addition, is also provided with one or more small through hole, small through hole is divided into the both sides of large through-hole, is all communicated with body upper part and body lower part.
Preferably, described conductive layer is woven wire.
A kind of high voltage power cable protection tube provided by the utility model, has the effect of waterproof and electric field shielding, has stopped the potential safety hazard of cable in transmitting procedure, has reduced the maintenance cost in later stage.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described.
Fig. 1 is the cutaway view of a kind of high voltage power cable protection tube disclosed in the utility model embodiment.
Numeral in figure:
1, top 2, bottom 3, absorbent wool 4, woven wire 5, large through-hole
6, small through hole.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Embodiment:
As shown in Figure 1, a kind of high voltage power cable protection tube, comprising:
Body, this body is divided into two parts, top 1 passing through for cable, and bottom 2, in crescent shape, is separated by one section of circular arc with top 1;
The inside, top 1 of above-mentioned body is provided with one deck conductive layer, the bottom 2 of body is filled with absorbent wool 3, meanwhile, be provided with large through-hole 5 between top 1 and bottom 2, this large through-hole 5 can be communicated with body exterior space, in addition, also be provided with one or more small through hole 6, small through hole 6 is divided into the both sides of large through-hole 5, is all communicated with body upper part 1 and body lower part 2, in addition, conductive layer is woven wire 4.
Implement principle: as shown in Figure 1, this figure is cutaway view, cable passes through on the top 1 of body, along with the time of buried underground is gradually of a specified duration, steam forms dewdrop and infiltrates in cable, the connecting points of protection tube when being connected generally is positioned at the level of circumference shown in figure and diameter two ends semicircle can divided equally, once formation dewdrop, moisture can flow downward along tube wall, infiltrate in water-absorbing sponge by small through hole 6, the moisture in protection tube is kept not stop, in addition, when moisture acquires a certain degree, under the pressure of cable, moisture also can be pressed into large through-hole 5 in Absorb Water cotton 3, flowed out by large through-hole 5, large through-hole 5 also has the function of heat radiation.In its tangible actual practical process, cable meeting distribute heat itself, the absorption of a moisture and the balance of evaporation can be maintained, therefore, large through-hole 5 assume responsibility in most cases one heat radiation function, woven wire 4 as a conductive layer, can with cable around concentrated electric field form a voltage stabilizing electric field, avoid concentrating electric discharge, conveying signal is had an impact.
A kind of high voltage power cable protection tube provided by the utility model, has the effect of waterproof and electric field shielding, has stopped the potential safety hazard of cable in transmitting procedure, has reduced the maintenance cost in later stage.
Above-described is only the preferred implementation of a kind of high voltage power cable protection tube provided by the utility model; should be understood that; for the person of ordinary skill of the art; under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
