Description
Technical field
The present invention relates to power cable connection areas, more particularly, to a kind of recovery cable body structure jointing.
Background technique
Due to the limitation of the factors such as the production technology of plastic insulating power cable, place, transport, plastic insulating power cable
General length be 500~1000 meters/volume, still, Urban Underground power grid, the lead line in power station, industrial and mining enterprises inside
Power supply and crossing river and sea submarine transmission line have tens meters, rice up to a hundred, several kilometers, thousands of kilometers differ, so must be every volume
Plastic insulating power cable is attached extension, to meet the requirement of design and construction.
The extended traditional method of the connection of power cable is then to carry out compression copper by the way that copper pipe to be sleeved on cable conductor
The tight cable conductor mode of pipe clamp, connects the end of two power cables, to realize that connection extends.But compression copper pipe clamping cables
The connection structure of conductor mode is not connected firmly, and is easily broken off, and junction conductivity is low, and radial electric field loss is big, electric energy damage
Consumption is big, has seriously affected the current-carrying capacity of power cable, and connection construction very complicated, it is difficult to restore cable body knot completely
Structure, to reach plant produced level；
With the progress of science and technology and technique, there are a variety of different cable connector interconnection techniques again in recent years:
Such as Chinese patent publication No. are as follows: the patent of CN106024133 discloses a kind of " crosslinked polyethylene fusing type insulated electro
Cable joint and its manufacture mounting process ", text in describe: using explosion weldering welding manner connection conductor；By semi-conductive adhesive band from
The end inner semiconductor layer of former cable body is wound on the end inner semiconductor layer of other end cable body, forms the interior of cable connector
Semiconductor layer；Crosslinked polyetylene insulated adhesive tape is wrapped on inner semiconductor layer, insulating layer and the insulation with former cable are formed
Layer overlap joint, is then heated, its internal insulating layer fusing is made, and semiconductive strip material is not and production cable semi-conductive material
It is identical, also can not phase melt close and form microcosmic air gap, will lead to the distortion of electric field；
For another example Chinese patent publication No. are as follows: the patent of CN 106329268 discloses a kind of " crosslinked polyetylene insulated electric power
The wrapped molding production method of cable intermediate joint ", text in describe: the exothermic weld mode combined using mold with welding powder is connected
Connect conductor；Then semiconductive port and conductor are cleaned, then wrapped semiconductive band；Followed by using identical as cable insulation
The crosslinked polyetylene insulated vulcanization band of material after carrying out wrapped recovery, makes factory's insulating layer, interior semi-conductive layer by heating and hands over
Connection polyethylene insulation vulcanization band is melted into an insulating layer entirety, realizes the recovery of interior semi-conductive layer, insulating layer.
The cable connection structure and technique that above-mentioned 2 patent documents are recorded have following deficiency:
1, be the shortcomings that exothermic weld: exothermic weld impurity is more, and replaces the high temperature for reacting and generating up to 2800 DEG C, and leads
Just 1083 DEG C of the fusing point of body copper, makes the seriously tired decline of copper material tensile strength because of heat release high temperature in welding process, lose
The tensile strength of former cable conductor；The mechanical strength damage decline of copper material and the impurity of exothermic weld displacement copper are farther
It is more than the impurity content of fine copper, conductivity is caused to decline, seriously affects the current-carrying capacity of cable.
2, interior semi-conductive layer is wound at connection construction scene using semi-conductive adhesive band, is then reheated welding and is formed, due to
Construction site environment is more severe, and the adhesive tape in winding process inherently has a natural phenomena of Electrostatic Absorption dust, in operation
Bring the impurity such as dust into；Simultaneously because the formation of semiconductive strip material interlayer drop is uneven, it is unable to ensure interior semi-conductive layer and restores
High smooth flat surface afterwards, cannot effectively constant and uniform shielding high potential field distribution, bury serious electrical property hidden danger；
3, insulating layer is wrapped using crosslinked polyetylene insulated vulcanization band progress at connection construction scene, then reheats welding
It is formed.The technique equally exists problem of environmental pollution, simple and crude severe construction operation site environment, winding insulation band process because
Electrostatic strip adsorbs the impurity such as dust, and specification can be complied with standard by being unable to ensure the cleanliness after insulating layer restores, and gives cable connection
Artificially cause a hidden trouble.
4, entire production technology
Consuming time is long for technique, 7 hours general used times, long 10 a few houres of needs.
