Abstract

A kind of device reducing transmission line of electricity electromagnetic radiation, including overcoat, described overcoat is hollow, the cylindrical shape of both ends open in middle part, is provided with electro-magnetic screen layer in described overcoat, described overcoat is provided with an opening vertically, and described overcoat is contained on transmission line of electricity by described opening sleeve.The present invention can be greatly reduced overhead transmission line electromagnetic radiation intensity, can dissolve under line the contradiction between resident and power supply department, save track remodelling funds.

Description

A kind of device reducing transmission line of electricity electromagnetic radiation
Technical field
The present invention relates to a kind of device reducing transmission line of electricity electromagnetic radiation.
Background technology
Operating transmission line wire can produce certain electromagnetic radiation, and this radiant intensity is with the increasing of distance Add constantly decay.China is vast in territory, and overhead transmission line distribution is multi-point and wide-ranging, and circuit cannot be avoided wearing More residential block or population activity compact district, transmission line wire electromagnetic radiation usually cause these regions resident with Dispute between power supply department.Conventional solution is by two kinds, and one is the overhead power transmission by crossing over residential block Track replacement is for putting cable underground, and two is to build screening cage outside resident house.But, the former expend huge and Add difficulty to later stage O&M, though the latter spend less owing to having influence on nothing in the outward appearance of house owed by a citizen and room Line communication apparatus signal is often difficult to obtain the agreement of resident.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art to provide one that overhead power transmission can be greatly reduced Circuit electromagnetic radiation intensity, can dissolve under line the contradiction between resident and power supply department, save track remodelling The device reducing transmission line of electricity electromagnetic radiation of funds.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of device reducing transmission line of electricity electromagnetic radiation, including overcoat, described overcoat be middle part hollow, two The cylindrical shape of end opening, is provided with electro-magnetic screen layer in described overcoat, described overcoat is provided with an opening vertically, Described overcoat is contained on transmission line of electricity by described opening sleeve.
Described outer casing internal diameter is more than the external diameter of transmission line of electricity.
The side of the opening of described overcoat is provided with groove, and opposite side is provided with and the fin of described groove match, Described fin makes the closure of openings of described overcoat in being inserted into described groove.
Described overcoat is sequentially provided with external insulation layer, gauze screen and inner insulating layer from outside to inside.
Owing to using such scheme, this device has electro-magnetic screen layer by being set with one outside transmission line of electricity Overcoat, thus reduce the effect of transmission line of electricity electromagnetic radiation, overcoat is provided with an opening vertically, this Sample during practice of construction, by coat suit outside transmission line of electricity by very convenient, so substantially increase The speed of construction, and the side, opening both sides of overcoat is provided with groove, and opposite side is provided with fin, so incite somebody to action this Fin only need to be snapped in groove after being sleeved on outside transmission line of electricity by device, of course in order to be effective, then Spread upon by special super glue and snap in fin after in groove again and so can ensure that the both sides sealing envelope of opening Closing, thus ensure the effect of shielding, it is ensured that the quality of construction, this device can make regular length, it is possible to To make volume a volume, then in work progress, it is actually needed flexible cutting arrangement according to user.
In sum, this device is possible not only to be greatly reduced electromagnetic radiation intensity below overhead transmission line, also The contradiction between resident and power supply department can be dissolved under line, save circuit technological transformation funds.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings, specific implementation of the patent mode is further described.
As it is shown in figure 1, a kind of device reducing transmission line of electricity electromagnetic radiation, overcoat in this example from outward to Inside being sequentially provided with external insulation layer 1, gauze screen 2 and inner insulating layer 3, external insulation layer 1 uses high-temperature vulcanized silicon rubber Glue laminated system, its thickness is 1.5mm, a width of 25mm, a length of 10000mm;Gauze screen 2 uses commercially available 100 Icteric sclera copper mesh is tailored, a width of 20mm, a length of 10000mm;Inner insulating layer 3 uses high-temperature silicon disulfide rubber Compacting, its thickness is 2mm, a width of 25mm, a length of 10000mm;Gauze screen 2 be placed in brush in advance glutinous Centrally above, external insulation layer 1 is placed in above gauze screen 2 inner insulating layer 3 of mixture, external insulation layer 1 with Aliging in each limit of inner insulating layer 3, uses special equipment by the external insulation layer 1 arranged, gauze screen 2 and interior insulation Layer 3 is compressed to one.The width of the screen layer being compressed to one can customize according to actual wire diameter, Length also can customize according to actual needs.Described overcoat is hollow, the cylindrical shape of both ends open in middle part, described Overcoat is provided with an opening vertically, and described overcoat is contained on transmission line of electricity by described opening sleeve.Described overcoat The side of opening be provided with groove, opposite side is provided with and the fin of described groove match, described fin plug-in mounting The closure of openings of described overcoat is made in described groove.
