Abstract
The invention relates to a cable reducer conductor connecting structure for a nuclear power plant. Various coating layers A and coating layers B of the end parts of all large-section cables and small-section cables used for connection are stripped so as to expose conductors A and conductors B. The conductors A of the end parts of all the large-section cables and the conductors B of the end parts of all the small-section cables are respectively inserted into large-bore pipes and small-bore pipes of reducer copper pressure welding pipes. All the reducer copper pressure welding pipes are arranged in a staggered mode in the horizontal direction of the cables. Each reducer copper pressure welding pipe is pressed so that both ends of the reducer copper pressure welding pipe are respectively pressure-welded with the conductor A and the conductor B closely. A new insulation layer is injected and molded at the periphery of each pressure-welded cable reducer conductor connecting structure. A new sheathing layer is injected and molded at the periphery of the whole new insulation layer of the entire cable connection part, and the new sheathing layer needs to be respectively overlapped and combined with an original sheathing layer A of each large-section cable and an original sheathing layer B of each small-section cable. The cable reducer conductor connecting structure for the nuclear power plant has low smoke, zero halogen, fire resistance, high temperature resistance, water blocking, damp prevention and long service life.
Description
Technical field
The present invention relates to a kind of syndeton of cable, particularly a kind of cable reducer conductor connecting structure for nuclear power plant.Belong to technical field of electric wires and cables.
Background technology
In recent years, acceleration along with the pace of construction of China's nuclear power station, the demand of the related industry that matches with nuclear power station sharply increases, and makes great efforts the production domesticization of the relevant corollary equipment of raising nuclear power station, realizes that the great-leap-forward development of China's nuclear power station corollary equipment is imperative.And cable is exported the part that all is absolutely necessary as nuclear power station internal operation and electric power, also is an important supporting original paper of electric power system.Cable is directly connected to fail safe, the reliability of nuclear power station.The wherein fail safe that is connected and is directly connected to cables of nuclear power, the reliability of heavy caliber cable and small-bore cable.
Summary of the invention
The purpose of this invention is to provide a kind of have low cigarette, Halogen, fire resistance, resistant to elevated temperatures, cable reducer conductor connecting structure for nuclear power plant moistureproof, long service life blocks water.
Technical scheme of the present invention is: a kind of cable reducer conductor connecting structure for nuclear power plant.Stripping goes with the integument A that is made up of each layers such as restrictive coating, screen and insulating barriers of the electric cable with large cross-section end of what connection electric conductor A to be exposed.Stripping goes with the integument B that is made up of each layers such as restrictive coating, screen and insulating barriers of the small bore cable end of what connection electric conductor B to be exposed.Each electric conductor A inserts respectively in the large-diameter pipe of reducing copper aluminium hydraulic pressed connecting pipe with top electric cable with large cross-section end.Each electric conductor B inserts respectively in the small-bore pipe of reducing copper aluminium hydraulic pressed connecting pipe with top small bore cable end.The setting of on the cable longitudinal direction, staggering of each reducing copper aluminium hydraulic pressed connecting pipe.Pressing each reducing copper aluminium hydraulic pressed connecting pipe closely is crimped on reducing copper aluminium hydraulic pressed connecting pipe two ends respectively with electric cable with large cross-section end electric conductor A and small bore cable end electric conductor B.The reducing copper aluminium hydraulic pressed connecting pipe peripheral injection moulding new insulating barrier good in each crimping makes reducing copper aluminium hydraulic pressed connecting pipe and electric conductor A and electric conductor B all be wrapped in new insulating barrier Inner.The new the thinnest dot thickness of insulating barrier is not less than 1.0mm.The new restrictive coating of the peripheral injection moulding of whole new insulating barrier in whole cable junction.New restrictive coating should combine with former restrictive coating A of electric cable with large cross-section and the former restrictive coating B of small bore cable overlaid respectively, and the new the thinnest dot thickness of restrictive coating is not less than 1.5mm.
Described reducing copper aluminium hydraulic pressed connecting pipe is directly chosen commercially available box-like existing product according to large and small cable port.
Described new insulating barrier is selected cross-linking polyethylene materials for use.Can finish crosslinkedly after this material injection moulding under heating condition, this new insulating barrier can long-term work under 90 ℃ of temperature.
Described new restrictive coating is selected the thermoplastic elastic material with low cigarette, Halogen, fire resistance for use.This new restrictive coating has low cigarette, Halogen, fire-retardant function.
Because the insulating barrier of part of the present invention adopts cross-linking polyethylene materials, can finish crosslinked under heating condition.Sheath adopts low cigarette, Halogen, fire-retardant thermoplastic elastic material, and this just makes cable of the present invention have the characteristic of low cigarette, low toxicity.Because of conductor, joint, insulation are injected into a whole by sheath, so have the good advantages such as moisture that block water, hinder.
Advantage of the present invention provided a kind of have low cigarette, Halogen, fire resistance, resistant to elevated temperatures, cable reducer conductor connecting structure for nuclear power plant moistureproof, long service life blocks water.
