Embodiment 1

[0074] The wiring device is divided into signal generating device (14-core number T1~T14), receiving device (14-core number R1~R14), all of which have working indicator lights. When the indicator light of the occurrence port is on, it means sending a high level; when the indicator light of the receiving port is on, it means it is receiving a high level. Assume that the generator is at end A of the cable and the receiver is at end B.

[0075] The line device works periodically:

[0076] (1) In each cycle, the terminal indicator light will be fully lit m times at the same time (according to the cable number setting, in fact, at this time, the fixed T1 is set to be low and not lit to ensure that other ports form a loop to work without affecting the logical judgment. The following "full “on” means T2~T14 are all on); if the receiving device is randomly connected on the other side of the cable, its indicator lights will also be all on for m times.

[0077] (2) After all lights ar...

Embodiment 2

[0086] 1. Place the generator;

[0087] (1) Connect the A end of the cable to the generating device: mark the core of the 10-core cable, put on the sleeve and insert the cable into the cable core slots A1, A2, A3..., A14 corresponding to the generating end in sequence, And record the corresponding relationship between the bushing name and the generating end, the table is as follows:

[0090]

[0091] (2) Set the number of the cable: the default setting is cable No. 1 when the power is turned on, and the digital tube displays 1; if you want to mark the cable as a No. m cable (this device can be set to No. The number of times the core sends signals at the same time, so that the digital tube displays the number m. Press and hold the cable identification button again to confirm the start of the signal generation step.

[0092] When entering the signal generation step, first, the signal generation indicators of all cable cores except ...

Abstract

The invention provides a power cable and cable core alignment method and device, and the method comprises the steps: transmitting preset signals at two ends of a cable by taking a detected cable as a carrier, and finding out a corresponding relation between two ends of a cable core through checking and recording a preset signal time sequence and a received signal time sequence; meanwhile, adding cable identification information before the time sequence signals are transmitted to distinguish the cables, and achieving the function of distinguishing multiple cables and cable cores at the same time. According to the method and device, only one person is needed to complete cable alignment work according to the preset signal at one end of the cable and the received signal at the other end of the cable, so that the influence of wireless communication on protection and automation devices is avoided, the labor cost is further reduced, the error rate caused by manual communication is avoided, the alignment process is simplified, and the alignment accuracy and the working efficiency are improved; and the requirements of safe, efficient and low-cost secondary cable alignment on an electric power production site are met.

Description

technical field [0001] The invention belongs to the technical field of cable detection, and in particular relates to a power cable and a cable core alignment method and device. Background technique [0002] In electric power construction projects, electric power production personnel are under high pressure to transmit power and the construction period is tight. Communication, automation, and protection personnel need to do a lot of cable alignment work when installing, overhauling, and maintaining secondary equipment. [0003] The traditional wiring process is divided into four steps: determining the cable, determining the fixed end, finding the path, and marking. [0004] Determine the cable: When laying the cable, both ends of the cable have been marked, and you can find the corresponding ends of the cable according to the marks. If the cable has no marks, you must "touch" the cable again to determine the two ends of the cable to be tested; end) There are at least 1 staf...
