Description

Technical Field

[0001] The invention relates to the technical field of power system control, in particular to a portable wireless line calibrator dedicated to control cables and a calibration method. Background Art

[0002] At the power system site, the commonly used method for line calibration is to use a multimeter (or light) to measure the on-off and use an intercom to assist in calibration. Similar products on the market currently use the method of measuring high and low levels to distinguish different lines. They can only detect whether they are unobstructed, but cannot know the name of the line, and cannot effectively identify live cables, which will bring certain potential faults. Through consultation and investigation of domestic units in the same industry, it was found that most units use the on-off gear of the multimeter to measure the on-off of the ground or the spare core to determine the correctness of the core. There is no effective means to simply, quickly and accurately determine the correctness of large quantities of multiple pairs of cable cores. These methods are not only time-consuming and labor-intensive, but also prone to errors, which bring troubles to engineering construction. More importantly, it is restricted by the prohibition of wireless communication in many high-frequency equipment applications.

[0003] Control cables are widely used in power systems to transmit signals and analog quantities, and are an indispensable part of realizing the "four remotes" (remote signaling, telemetry, remote control, and remote adjustment) of power systems. The commonly used control cable specifications in power systems are 7*1.5, 14*1.5, 24*1.5, 9*2.5, 10*2.5, 4*4, 6*4, etc. (number of cable cores * nominal cross-sectional area of ​​GB / T9330 cable core conductor). During the implementation and installation of power projects, it is necessary to first lay the cable between electrical equipment, then check that each core at both ends of the cable is consistent, and then set the sleeve mark on the cable core end side, and finally connect the wires according to the drawings. If each core is not checked or checked incorrectly, it will not only cause the signal to fail to be sent or sent incorrectly, but also cause serious adverse consequences to electrical equipment and personnel. At the same time, in the future development of my country, the power system will be more important, and the demand for supply guarantee capacity will continue to increase. Therefore, it is very meaningful to check the control cable core correctly in the implementation of power system projects.

[0004] At present, the core verification method of power system control cable is as follows:

[0005] (1) Check according to the serial number marked on the wire core during the manufacturing process of the control cable. However, the marked serial number will be worn during the construction process, causing the writing to be blurred, and there are often marking errors.

[0006] (2) Take the 7*1.5 cable as an example (the two sides of the cable are assumed to be named A and B respectively), first ground one of the cores on the A side of the cable, use the on-off function of the multimeter on the B side, ground the positive probe of the multimeter, and touch each core on the B side in turn. When the multimeter buzzer sounds when it touches a core, it means that it is the same core, then put sleeves on both sides of this core to mark it, and check the remaining cores in the same way. This method requires two people to operate, the process is cumbersome, and it takes a long time and is prone to errors when checking control cables with a large number of cores.

[0007] Therefore, a professional and practical cable wireless calibration instrument is urgently needed to solve the above-mentioned technical problems. Summary of the invention
