Description
Technical field
It is particularly a kind of to recognize bar using cable the present invention relates to a kind of method that cable is recognized in cable upkeep operation
The method for recognizing Awaiting Overhaul cable.
Background technology
During cabling, typically by a plurality of cable laying in same leader cable raceway groove, each bar cable
Most passed through the branch cable raceway groove of leader cable raceway groove both sides afterwards.Because a plurality of cable interlaced arrangement is in leader cable raceway groove, and
Cable transfer is difficult the tendency of identification maintenance cable apart from long in maintenance process in the future, at present, identification maintenance cable tendency
Method be：The first is, every one identical identifying plate of certain length colligation, to be existed by searching colligation on each bar cable
The same identification board of each cable head end and tail end, so that it is determined that the tendency of correspondence cable；Second is to use cable identifier,
The signal generator of cable identifier is arranged on the tail end of Awaiting Overhaul cable, and the power supply of enabling signal generator passes through this
Cable installs the signal receiver of cable identifier one by one to head end transmission pulse signal, then in the head end of a plurality of cable, until
Warning light on signal receiver is lighted, so that it is determined that the head end of Awaiting Overhaul cable.
In first method, it is placed in conduit line because identifying plate is exposed for a long time, is influenceed Sign Board easily from electricity by weathering
Come off on cable or Sign Board is smudgy, lead to not recognize cable.In second method, the signal generator of cable identifier
It is installed to when on cable with signal receiver, it is necessary to the probe on signal generator and signal receiver is pricked into exhausted on cable
Edge skin, makes the probe on signal generator and signal receiver be contacted with the cable core in insulated hull respectively, due to cable
Alived on core, especially in the case of high-tension current, maintenance worker is easy to cause electric shock thing because of misoperation
Therefore, seriously jeopardize the life security of maintenance worker.
The content of the invention
In order to solve the above-mentioned technical problem the present invention is, there is provided a kind of utilization cable identification bar recognizes the side of Awaiting Overhaul cable
Method, it can not be affected by the external environment, and clearly, accurately identify cable tendency, and job safety, for maintenance worker provides safety guarantor
Barrier.
Technical solution of the invention is：
A kind of method that utilization cable identification bar recognizes Awaiting Overhaul cable, it is characterized in that and comprises the following steps that：
1st, during cabling, piece cable identification bar of parallel colligation, multiple-twin cable and cable are known outside each cable
Other bar is laid in leader cable raceway groove, and each pair of cable and cable identification bar are passed from corresponding branch cable raceway groove；
When the 2nd, overhauling cable, a maintenance worker is left at the leader cable channel inlet end of cable, by the identification of all cables
The head end ground connection of bar；
3rd, the port of export in Awaiting Overhaul cable leaves a maintenance worker, by the corresponding cable identification bar tail of Awaiting Overhaul cable
Terminate into low-tension current；
4th, after thermo colour discoloration, stay in leader cable channel inlet end and stay in two maintenance at Awaiting Overhaul cable outlet end
After workman has had found thermo colour discoloration, other side is informed by intercom, the cable identification bar of thermo colour discoloration is corresponding
Cable is Awaiting Overhaul cable head, and disconnects the power switch of the cable；
5th, Awaiting Overhaul cable and its corresponding cable identification bar are extracted out, and new cable and cable identification bar is laid in
In leader cable raceway groove and its corresponding branch cable raceway groove, new cable is accessed into circuit；
The cable identification bar includes resistance wire, and thermo colour layer is coated with the resistance wire, is applied in the temperature-sensitive
The bed of material is coated with transparent insulating sheath.
The beneficial effects of the invention are as follows：Because the cable recognizes bar, applied by resistance wire, the temperature-sensitive being coated on outside resistance wire
The bed of material, the insulating sheath being coated on outside thermo colour layer are constituted, and resistance wire produces heat when being powered, and thermo colour layer occurs
Metachromatism, it is not affected by the external environment, and clearly, accurately identifies cable tendency, and in operating process, what resistance wire led to is low
Current voltage, upkeep operation is convenient, safety, for maintenance worker provides safety guarantee.
Brief description of the drawings
Fig. 1 is cable identification bar structural representation of the invention；
In figure：1- resistance wires, 2- thermo colours layer, 3- insulating sheaths.
Specific embodiment
As illustrated, a kind of cable identification bar, including resistance wire 1, thermo colour layer 2 is coated with the resistance wire 1,
Transparent insulating sheath 3 is coated with thermo colour layer 2.
A kind of method that utilization cable identification bar recognizes Awaiting Overhaul cable, comprises the following steps that：
1st, during cabling, piece cable identification bar of parallel colligation, multiple-twin cable and cable are known outside each cable
Other bar is laid in leader cable raceway groove, and each pair of cable and cable identification bar are passed from corresponding branch cable raceway groove；
When the 2nd, overhauling cable, a maintenance worker is left at the leader cable channel inlet end of cable, by the identification of all cables
The head end ground connection of bar；
3rd, the port of export in Awaiting Overhaul cable leaves a maintenance worker, by the corresponding cable identification bar tail of Awaiting Overhaul cable
Terminate into low-tension current；
4th, after thermo colour discoloration, stay in leader cable channel inlet end and stay in two maintenance at Awaiting Overhaul cable outlet end
After workman has had found thermo colour discoloration, other side is informed by intercom, the cable identification bar of thermo colour discoloration is corresponding
Cable is Awaiting Overhaul cable head, and disconnects the power switch of the cable；
5th, Awaiting Overhaul cable and its corresponding cable identification bar are extracted out, and new cable and cable identification bar is laid in
In leader cable raceway groove and its corresponding branch cable raceway groove, new cable is accessed into circuit.
Specific embodiment of the invention is these are only, is not intended to limit the invention, for those skilled in the art
For member, the present invention can have various modifications and variations.All any modifications within the spirit and principles in the present invention, made,
