Abstract

The invention discloses a novel copper alloy sheath through ground wire comprising a cable core. The cable core comprises multiple copper wires which are twisted together. The cable core at least comprises one test wire. The external side of the cable core is sleeved with a metal external sheath. Each copper wire is externally provided with a protective layer. The cable core is composed of 7 copper wires or 19 copper wires, and a twisting mode is a layer-twisting mode or a concentric mode. The test wire is an insulating single wire which is an aluminum wire with an insulating layer or a copper wire with the insulating layer. There are one or two test wires. The technical problems that existing through ground wires pollute environment, and damage or broken parts cannot be rapidly found are solved so that the through ground wire is conductive, environment-friendly and corrosion-resistant with a broken wire alarm characteristic.

Description

New copper alloy sleeve Through ground wire
Technical field
The present invention relates to the improvement of a kind of railway Through ground wire structure.
Background technology
Through ground wire is a kind of signal Special grounding cable of unifying earthing mode on railway signal system employing all fronts road, and it can guarantee full line-to-ground equipotential, eliminates the unsymmetrical current causing due to the potential difference between distinct device.Because Through ground wire is connected with ground and rail, can meet the requirement of the long-term good earth resistance value of large-scale grounding system, realize the effective protection to personnel and equipment.For meeting the stricter instructions for use of railway ground connection, need to develop a kind of have conductivity, environment-friendly type, corrosion resistance, Through ground wire with break alarm.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of new copper alloy sleeve Through ground wire, it not only long service life, environmentally safe and also can find out fast damage or disconnect position.
In order to solve the problems of the technologies described above, new copper alloy sleeve Through ground wire of the present invention, comprises cable core, and described cable core comprises many copper cash that twist together, and at least also comprises a p-wire in this cable core, is enclosed within metallic jacket in the outside of described cable core.
Every described copper cash is outside equipped with protective layer.
Described cable core is made up of 7 copper cash or 19 copper cash, and its stranded mode is layer-twisted type or concentric type.
Described p-wire is insulated single wire, and described insulated single wire is the aluminum steel of tape insulation layer or the copper cash of tape insulation layer.
The quantity of described p-wire is one or two.
Tool of the present invention has the following advantages:
1, environment friendly and pollution-free.Metal outer jacket in Through ground wire of the present invention meets the earth resistance requirement of Through ground wire, and corrosion-resistant and even nonpollution material, can not pollute soil.
2, can find out fast and damage or disconnection position.The p-wire of at least one tape insulation layer is set in cable core of the present invention, if Through ground wire damages under external force or disconnects, can cause the disconnection of this p-wire simultaneously, cause warning system warning, now searching and calculating by instrumentation, maintenance personal can find the gap of p-wire fast, has also found fast damage or the gap of Through ground wire simultaneously.
3, long service life.Metal outer jacket of the present invention can play well anticorrosion and protective action to the copper cable core in Through ground wire, can guarantee in the environment of inclement condition of Through ground wire long-term work, and be able to take high vibration, long service life.
The explanation of accompanying drawing drawing
Fig. 1 is the structural representation of a kind of embodiment of new copper alloy sleeve Through ground wire of the present invention;
Fig. 2 is the structural representation of the another kind of embodiment of new copper alloy sleeve Through ground wire of the present invention.
Wherein: 1-cable core 2-copper cash 3-protective layer 4-p-wire 5-metallic jacket.
Specific embodiments

According to cable core area difference, can adopt the copper cash of different-diameter; For meeting different needs, cable core internal layer and skin also can adopt different radicals to coordinate.
As shown in Figure 2, new copper alloy sleeve Through ground wire comprises cable core 1, the TR type annealed copper wire 2 that this cable core 1 is 1.53mm by 19 diameters is stranded by concentric type, 1 copper cash 2 is placed in center, all the other 18 copper cash 2 are two-layer circumferential arrangement around center copper cash 2, wherein internal layer is uniformly distributed 6 copper cash 2, and skin is uniformly distributed 12 copper cash 2, is provided with two p-wires 4 in cable core 1; Be enclosed within metallic jacket 5 in the outside of described cable core 1, the material of this metallic jacket 5 is copper alloy, also can adopt metal or its copper alloy or its rare earth alloy of the environmentally safes such as tin, zinc, magnesium, nickel, as rare earth aluminium alloy etc.
P-wire 4 can be the aluminum steel of tape insulation layer or the copper cash of tape insulation layer, and wherein the copper cash of tape insulation layer comprises enamel covered wire, plastics copper cash, especially take high density polyethylene (HDPE) insulating barrier copper cash or irradiation crosslinked polyolefin insulating layer copper cash as good.
According to cable core area difference, can adopt the copper cash of different-diameter; For meeting different needs, cable core internal layer and skin also can adopt different radicals to coordinate.
