Abstract
The utility model relates to a cable leak protection oil structure, wherein: fixed mounting has the protective housing on the line body insulating layer outer wall, is equipped with the pressure vent on the lateral wall of protective housing, is equipped with the oil storage bag in the protective housing, and the oil storage bag is linked together with the inside sinle silk space of line body insulating layer. The utility model discloses carry out institutional advancement to the cable, the increase sets up a vacuum oil storage bag, and after the inside oil pressure of cable risees, unnecessary insulating oil will reach the purpose of the inside oil pressure of release cable in entering into vacuum oil storage bag through space between the sinle silk, reduces the risk that insulating oil oozes and the oil leak, ensures that the insulating properties of cable inside is not influenced.
Description
Technical Field
The utility model belongs to the technical field of the wire and cable technique and specifically relates to a cable leak protection oil structure.
Background
The cable is an electric energy or signal transmission device, usually constitute by several or several groups of wire, trades such as mainly used electric power system and information transmission, at present, in order to solve the inside insulating problem of cable better, all can pour into insulating oil in space 2 between the sinle silk of cable inside, then sealed, however, the cable inner conductor is resistive, can produce the heat after the circular telegram, and then will expand after can making the metal sinle silk be heated, and then can compress the space between the sinle silk, and then inside oil pressure has been increased, the oil pressure risees the back, ooze from sealing element easily, the oil leak phenomenon appears, will reduce the inside insulating properties of cable after the oil leak.
Disclosure of Invention
The utility model aims at designing a cable leak protection oil structure, carrying out institutional advancement to the cable, the increase sets up a vacuum oil storage bag, and after the inside oil pressure of cable risees, unnecessary insulating oil will enter into the vacuum oil storage bag through the space between the sinle silk in, reaches the purpose of the inside oil pressure of release cable, reduces the risk that insulating oil oozes and the oil leak, ensures that the inside insulating properties of cable is not influenced.
In order to achieve the above object, the utility model adopts the following technical scheme:
a cable oil leakage prevention structure comprises a wire body insulating layer, a gap between wire cores, a protective shell, a pressure discharge hole and an oil storage bag; wherein: fixed mounting has the protective housing on the line body insulating layer outer wall, is equipped with the pressure vent on the lateral wall of protective housing, is equipped with the oil storage bag in the protective housing, and the oil storage bag is linked together with the inside sinle silk space of line body insulating layer.
An oil leakage prevention structure for a cable, wherein: the interior of the oil storage bag is vacuumized.
Compared with the prior art, the utility model discloses carry out institutional advancement to the cable, the increase sets up a vacuum oil storage bag, and after the inside oil pressure of cable risees, unnecessary insulating oil will reach the purpose of the inside oil pressure of release cable in entering into the vacuum oil storage bag through space between the sinle silk, reduces the risk that insulating oil oozes and the oil leak, ensures that the inside insulating properties of cable is not influenced.
Drawings
Fig. 1 is a schematic diagram of the structure of the present invention.
Reference numerals: line body insulating layer 1, sinle silk interval 2, protective housing 3, row's pressure hole 4, oil storage bag 5.
Detailed Description
The following embodiments are further described with reference to the accompanying drawings.
Embodiment 1, please refer to fig. 1, a cable oil leakage prevention structure includes a wire insulating layer 1, a gap 2 between wire cores, a protective shell 3, a pressure discharge hole 4, and an oil storage bag 5; wherein: fixed mounting has protective housing 3 on the 1 outer wall of line body insulating layer, is equipped with row pressure hole 4 on the lateral wall of protective housing 3, is equipped with oil storage bag 5 in the protective housing 3, and oil storage bag 5 is linked together with the sinle silk inter space 2 of 1 inside of line body insulating layer.
The working principle is as follows: at present, in order to solve the inside insulating problem of cable better, all can inject insulating oil in space 2 between the sinle silk of cable inside, then sealed, but, can produce the heat after the cable circular telegram, and then can make the metal sinle silk be heated the back and will expand, and then can compress space 2 between the sinle silk, and then increased inside oil pressure, the oil pressure risees the back, ooze easily from sealing element, the oil leak phenomenon appears, will reduce the inside insulating properties of cable behind the oil leak, this structure sets up a vacuum oil storage bag 5 that is linked together with space 2 between the sinle silk, after the oil pressure risees, unnecessary insulating oil will enter into in vacuum oil storage bag 5 through space 2 between the sinle silk, reach the purpose of the inside oil pressure of release cable, reduce the risk that insulating oil oozes and the oil leak, ensure that the inside insulating properties of cable is.
Claims (2)
