Abstract
The utility model discloses an alloy sheath railway through ground wire with broken string alarming function, include from outer ground wire sheath, cable core, warning wire sheath and the warning wire that sets gradually in to. When artificial or other exogenic actions lead to railway through ground wire breaking occur, the utility model provides a warning wire can form and open a way, and the staff can utilize test equipment, through electric capacity method of testing, resistance test method, low pressure pulse reflection method of testing or intelligent bridge test method, test disconnection fault to railway through ground wire trouble can be carried out and the distance is declared. Utilize alloy sheath railway through ground wire with broken string alarming function, gather in real time through monitoring system the utility model provides a warning traverse loop circuitous resistance and pulse -echo wave form carry out intelligent analysis, can realize railway through ground wire's real -time fault monitoring, are favorable to the railway to synthesize ground system's steady operation.
Description
Technical field
The utility model relates to a kind of railway run-through ground line, particularly relates to a kind of alloy sleeve railway run-through ground line with break alarm function.
Background technology
Railway run-through ground line is a kind of cable unifying ground connection for railway combined grounding system all fronts electromechanical equipment, it can make each working point earthing potential of large-scale Railway Electric system substantially be consistent, make system equipment grounding safety reliable, eliminate the current potential imbalance because the potential difference between distinct device causes, realize the effective reliable protection to personnel and equipment.Existing railway run-through ground line mostly is metal or alloy sheath railway run-through ground line, comprises twisted copper conductors and is coated on the oversheath of twisted copper conductors outside, and twisted copper conductors adopts that many red copper conductors are mutually stranded to be formed, and oversheath adopts Cu alloy material.Existing railway run-through ground line does not possess break alarm function, disconnects or be not easily found when there are other faults when Through ground wire.
In addition, when Through ground wire also adopts conductive plastic jacket, also once there is break alarm conductive plastic jacket Through ground wire product, but holding wire many employings common polythene of this series products, crosslinked polyethylene or elastomer etc. are as insulating material, very easily there is stranded damage or season cracking phenomenon, warning function is lost.
Utility model content
The purpose of this utility model is to provide a kind of alloy sleeve railway run-through ground line with break alarm function, can when causing Through ground wire that fracture occurs because of artificial or other External Force Actings, coordinate testing equipment to utilize the mode of testing capacitor or resistance to feed back broken string information, and carry out alarm in time.
The utility model adopts following technical proposals:
There is an alloy sleeve railway run-through ground line for break alarm function, comprise the ground wire sheath, cable core, warning wire sheath and the warning wire that set gradually from outside to inside.
Described ground wire sheath adopts copper sheath or copper alloy sheath.
Described cable core adopts stranded round copper conductor.
Described warning wire sheath adopts many group watt shape twisted copper conductors, and many group watt shape twisted copper conductors are combined to form circular jacket.
Described warning wire adopts insulated wire cores.
Described ground wire sheath is closely coated on cable core outer surface.
When artificial or other External Force Actings cause railway run-through ground line that fracture occurs, warning wire in the utility model can form open circuit, staff can utilize testing equipment, by capacity measurement method, the resis tance method of surveying, action of low-voltage pulse reflection measurement method or intelligent bridge test method, test disconnection fault, and railway run-through ground line fault can be carried out sentence distance.Utilize the alloy sleeve railway run-through ground line with break alarm function described in the utility model, intellectual analysis is carried out by the warning wire loop resitance in monitoring system Real-time Collection the utility model and pulse-echo waveform, the real time fail monitoring of railway run-through ground line can be realized, be conducive to the stable operation of railway combined grounding system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is done with detailed description:
As shown in Figure 1, the alloy sleeve railway run-through ground line with break alarm function described in the utility model, comprises the ground wire sheath 1, cable core 2, warning wire sheath 3 and the warning wire 4 that set gradually from outside to inside.Described ground wire sheath 1 adopts copper sheath or copper alloy sheath, and ground wire sheath 1 is closely coated on cable core 2 outer surface, can the cable of available protecting railway run-through ground line inside and warning wire 4 not be damaged.Cable core 2 adopts stranded round copper conductor, to meet earial drainage effect.Warning wire 4 can adopt insulated wire cores, and warning wire sheath 3 is arranged on warning wire 4 outer surface, can when railway run-through ground line is squeezed or clash into available protecting insulated wire cores injury-free.Warning wire sheath 3 can adopt many group watt shape twisted copper conductors; many groups watts of shape twisted copper conductors are combined to form circular jacket; watt shape is checked conductor and is had structural stability; check conductor than typical circular and can bear larger extraneous pressure, can play the better advantage of the protected effect of warning wire.
During use, the utility model is embedded in underground.When the utility model normally uses, warning wire 4 normally; When the utility model causes phenomenon of rupture occurs because of artificial or other External Force Actings, warning wire 4 also can form open circuit, staff can utilize testing equipment, by capacity measurement method, the resis tance method of surveying, action of low-voltage pulse reflection measurement method or intelligent bridge test method, test disconnection fault, and railway run-through ground line fault can be carried out sentence distance.
Utilize the alloy sleeve railway run-through ground line with break alarm function described in the utility model, intellectual analysis is carried out by warning wire 4 loop resitance in monitoring system Real-time Collection the utility model and pulse-echo waveform, the real time fail monitoring of railway run-through ground line can be realized, be conducive to the stable operation of railway combined grounding system.
