Referring to fig. 1, an embodiment of the present application provides a cable identification method, including:
s100, applying a first voltage to an armor layer of a source end of a target cable in a plurality of cables to be tested.
The target cable means a cable that a user needs to identify. The plurality of cables under test is a set of cables including the target cable, wherein the number of the plurality of cables under test is more than three cables. Assuming that the cables to be tested are cables connected between the power distribution device and a cell, and selecting a target cable at one end of the power distribution device, one end of the power distribution device is a source end of the target cable, a user needs to identify the target cable in the cables to be tested at one end of the cell, and one end of the cell is a destination end of the cable to be tested. The structure of the cable to be tested comprises a cable conductor, an insulating layer and an armor layer, wherein the insulating layer is wrapped on the cable conductor, and the armor layer is wrapped on the insulating layer. The insulating layer can prevent the electric leakage of the cable conductor, and the armor layer can protect the cable conductor and the insulating layer from being damaged by external mechanical force, corroded by chemical gas and the like. The first voltage may be a safe voltage, and the present embodiment does not limit this as long as the function thereof can be achieved.

And S300, detecting the current value of the armor layer passing through the destination end of the cable to be determined.
And selecting any one cable from the cables to be tested at one end of the cell as the cable to be tested. The voltage value on the armor layer of the target end of the cable to be determined can be detected through a voltmeter, a voltage sensor or a voltage detection circuit and the like. The present embodiment does not limit this, as long as the second voltage can be obtained. The current value of the armor layer passing through the cable to be determined is detected, and a Rogowski coil, a current transformer and the like can be used. The present embodiment does not limit this, as long as the current value of the armor layer at the destination end of the cable to be measured can be obtained.
S400, obtaining the resistance value of the armor layer of the cable to be determined.
The resistance value of the armor layer of the cable to be determined refers to the resistance value of the armor layer of the cable to be determined, and mainly refers to the resistance value of the armor layer between the source end of the cable to be determined and the target end of the cable to be determined. The resistance value of the armor layer of the cable to be determined can be directly stored in a memory in computer equipment and can be directly obtained when the cable to be determined is used. The resistance value of the armouring layer of the cable to be determined can also be measured using a resistance measuring instrument. The present embodiment does not limit this, as long as the resistance value of the armor layer of the cable to be determined can be obtained.
And S500, calculating a voltage value according to the current value and the resistance value to obtain a third voltage.
And according to ohm's law, after acquiring the resistance value of the armor layer of the cable to be determined and the current value of the armor layer passing through the target end of the cable to be determined. According to the relation between the voltage value and the current value and the resistance value, the voltage value of the armor layer of the cable to be determined can be obtained through calculation and is recorded as a third voltage.
S600, determining whether the cable to be determined is a target cable or not according to the first voltage, the second voltage and the third voltage.
According to the voltage value applied to the armor layer of the source end of the target cable, namely the first voltage, the voltage value of the armor layer of the target end of the cable to be determined, namely the second voltage, and the voltage value of the armor layer of the cable to be determined, namely the third voltage, whether the cable to be determined is the target cable or not can be determined, namely whether the target end of the cable to be determined is the target end corresponding to the source end of the target cable or not can be determined. And if the cable to be determined is determined to be the target cable, stopping the implementation of the cable identification method. If the cable to be determined is not the target cable, step S200 needs to be executed, any one of the cables to be determined is reselected as the cable to be determined, the cable to be determined in the previous cable identification is updated, and steps S300 to S500 continue to be executed until the cable to be determined is determined to be the target cable. The present embodiment does not set any limitation to the specific procedure of determining whether the cable to be determined is the target cable based on the first voltage, the second voltage, and the third voltage.
In a specific embodiment, the user can number the destination ends of a plurality of cables to be tested, and sequentially select the cables to be tested to perform steps S300 to S500. Therefore, when the cables to be determined are reselected, the same cables are prevented from being selected, and the efficiency of cable identification can be improved.
In the cable identification method provided by this embodiment, a first voltage is applied to the armor layer at the source end of the target cable, a second voltage on the armor layer at the destination end of the cable to be determined is detected, a current value passing through the armor layer of the cable to be determined is detected, a third voltage is calculated, and whether the cable to be determined is the target cable is determined according to the first voltage, the second voltage, and the third voltage. Therefore, the target cable is identified through the armor layer of the cable to be detected, the work of a cable wire of the cable to be detected cannot be influenced, the cable to be detected does not need to be subjected to power failure treatment, and the identification efficiency can be improved. And the cable identification method provided by the embodiment is simple and high in practicability.
Referring to fig. 2, in an embodiment, the step S600 of determining whether the cable to be determined is the target cable according to the first voltage, the second voltage and the third voltage includes:
s610, obtaining a difference value of the first voltage and the third voltage to obtain a difference voltage.
S620, if the difference value between the second voltage and the difference voltage is smaller than a preset threshold value, determining that the cable to be determined is a target cable.
And calculating the difference between the voltage value applied to the armor layer at the source end of the target cable and the voltage value of the armor layer part of the cable to be determined, namely the difference between the first voltage and the third voltage, and recording as a difference voltage. And the difference value of the first voltage and the third voltage is the actual voltage value of the armor layer of the destination end of the cable to be determined. By judging the difference between the voltage value of the armor layer at the destination end of the cable to be determined, namely the second voltage, and the difference voltage, whether the cable to be determined is the target cable can be determined. If the difference value between the second voltage and the difference voltage is smaller than the preset threshold value, it is indicated that the measured voltage value of the armor layer of the target end of the cable to be determined is very close to the calculated actual voltage value of the armor layer of the target end of the cable to be determined, and the cable to be determined can be determined to be the target cable. And measuring the second voltage value and the current value, and obtaining the resistance value without errors, namely, under an ideal state, the second voltage and the difference voltage are equal, so that the cable to be determined is the target cable.
In the embodiment, whether the cable to be determined is the target cable or not can be determined through simple calculation and comparison, and the practicability of the cable identification method can be improved.
Referring to fig. 3, in an embodiment, the step S400 of obtaining the resistance value of the armor layer of the cable to be determined includes:
s410, obtaining the resistivity of the armor layer of the cable to be determined, the length between the source end and the destination end of the cable to be determined and the transverse cutting area of the armor layer of the cable to be determined.
And S420, obtaining a resistance value according to the resistivity, the length and the cross-sectional area based on the resistance law.
The law of resistance means that the resistance of the armor layer of the cable to be determined is in direct proportion to the length of the armor layer of the cable to be determined, is in inverse proportion to the cross-sectional area of the armor layer of the cable to be determined, and is also related to the material of the armor layer of the cable to be determined. The length of the armor layer of the cable to be determined refers to the length of the armor layer between the source end and the destination end of the cable to be determined, and the resistivity of the armor layer of the cable to be determined is related to the material of the armor layer. Based on a resistance law, the resistance value of the armor layer of the cable to be determined can be calculated according to the resistivity, the length and the cross-sectional area. In this embodiment, the user can store the resistivity, the length, and the cross-sectional area of the armor layer of the cable to be determined in advance in the memory of the computer device, and can directly obtain the resistivity, the length, and the cross-sectional area when the cable to be determined is used.
In a specific embodiment, the cable to be determined may be divided into preset sections according to the middle head of the cable, wherein the total length of the preset sections is the same as the length between the source end and the destination end of the cable to be determined. And calculating the resistance value of each section and adding the resistance values to obtain the resistance value of the armor layer of the cable to be determined. The error of the resistance value thus calculated is small. For example: assuming that the total length of the cable to be determined is 100 meters, the cable to be determined is divided into 4 sections according to the middle head of the cable, wherein the first section is 10 meters, the second section is 30 meters, the third section is 20 meters, and the fourth section is 40 meters. Based on a resistance law, calculating the resistance value of the armor layer of each section of the cable to be determined according to the resistivity and the cross-sectional area, and adding the resistance values of each end to obtain the resistance value of the armor layer of the cable to be determined.
Referring to fig. 4, in an embodiment, the cable identification method further includes:
s800, attaching a two-dimensional code mark on the surface of the cable to be determined, wherein the two-dimensional code mark comprises information of resistivity and a cross-cut area;
and S900, acquiring the resistivity and the transverse cutting area according to the two-dimensional code identification of the cable to be determined.
The method comprises the steps that two-dimension code marks are pasted on the surfaces of a plurality of cables to be tested, wherein the two-dimension code marks comprise resistivity and transverse cutting area information of an armor layer of the cables to be tested, and the resistivity and the transverse cutting area of the cables to be tested in the cables to be tested can be obtained by scanning the two-dimension code marks through computer equipment. In a specific embodiment, the two-dimensional code identification further comprises information of the material, conductivity and the like of the cable conductor, the material of the cable insulation layer, the material of the cable armor layer and the like.
In the embodiment, the resistivity and the transverse cutting area can be obtained by the computer equipment through scanning the two-dimensional code identification, and the method is very simple and convenient. Moreover, the electrical resistivity and the transverse cutting area of a plurality of cables to be detected do not need to be stored in a memory of the computer equipment, the storage space of the memory can be saved, the efficiency of acquiring the electrical resistivity and the transverse cutting area is improved, and the efficiency of identifying the cables can be improved.
