Description

Cable core identification device and method

Technical Field

The invention belongs to the technical field of cable detection, and particularly relates to a cable core identification device and method.

Background

In recent years, with the development of electric power construction, the development of a large number of new intelligent substations and the upgrading and reconstruction of old substations are faced. In the construction process of a transformer substation, a large number of secondary cables need to be laid, the lengths of the secondary cables are different from 20 meters to 150 meters, several to more than ten cables need to be laid at the same time at the same electrical interval, and the core checking work of the secondary cables is one of the major problems faced at the moment.

The checking methods adopted at present are mainly as follows: 1. checking the wire number of a cable core: however, cables of different manufacturers and different qualities have various problems, some cables have fuzzy line numbers, even the line numbers at two ends of a cable core of the cable are inconsistent, and the accuracy of core checking is low. 2. And checking the wire core by utilizing the on-off gear of the multimeter. Two maintainers communicate through the intercom from the both ends of cable, confirm a line number clear sinle silk or regard "earth" as "public core" at the both ends of cable earlier, and wherein one person tests the cable sinle silk with the break-make shelves of universal meter on one side of the cable, with its short circuit one by one with other sinle silks, checks the sinle silk according to buzzing signal. However, this method has many disadvantages: firstly, the construction method is easily interfered by a noisy environment of a construction site, misdelivery is easily caused in the process, a buzzing gear is not audible, and the rework rate is high; secondly, when the cable is too long, the resistance of a public wire core is increased, the buzzer of the multimeter is invalid, and at the moment, only the resistance of the wire core can be measured, so that the measurement is inaccurate and is not intuitive in a poor light environment; thirdly, the universal meter has more gears, is easy to adjust wrong gears and is easily influenced by artificial reasons; fourthly, the universal meter is large in size and inconvenient to carry about. 3. Intelligent secondary sinle silk check device based on high frequency communication. The secondary cable core checking device based on high-frequency communication, which consists of a signal generator and a signal receiver, realizes the checking of the core by the sending and receiving of a CPU control signal, but the method is realized by two sets of devices and is inconvenient to carry; the environment in the station is complicated, although the high frequency signal is quick and efficient, various filtering devices are required to be added to eliminate the interference of the noise on the site, the structure is complicated, the manufacturing cost is high, and the accuracy is difficult to ensure.
