Cable recognition device and recognition method

Abstract

The invention relates to a cable recognition device and a recognition method. The device comprises a host, an output line, a recognition soft coil and a receiving box, wherein the host is used to display a power supply state and an output state and used to send out an emission signal; the output line is used to transmit the emission signal to a to-be-recognized cable; the recognition soft coil is used to receive a sensing signal of the to-be-recognized cable; and the receiving box is used to receive and display the sensing signal. The method comprises the steps that the host outputs the emission signal; the output line transmits the emission signal to the to-be-recognized cable; the recognize soft coil receives the sensing signal of the to-be-recognized cable; a receiving machine identifies the sensing signal, extracts a pulse sting, carries out phase detection of the pulse string, and displays a pulse waveform and a pulse direction obtained after the detection; and according to the pulse waveform and the method, whether the to-be-recognized cable is a target cable can be determined, or whether a fault exists in the to-be-recognized cable can be judged. In comparison with the prior art, the device and the method provided by the invention have the advantages that power supply is convenient; use is simple; judgment is visualized; one device can be used for multiple purposes; and the device can be used at complicated sites, etc.

Description

technical field [0001] The invention relates to power system detection technology, in particular to a cable identification device and identification method. Background technique [0002] Cable identification is of great significance in cable construction and maintenance work. With the wide application of power cables in power systems, on the one hand, cable faults are increasing, and on the other hand, cable migration and reconnection involved in various roads, municipal construction and renovations are also very common. It can be seen that identifying the target cable from a group of cables is a very important task in cable engineering. At present, there are instruments for identifying power-off cables and instruments for identifying live cables on the market. However, in actual use, the actual cables are often placed and pressed together on the spot, and the caliper used by the instrument is often unable to be clamped, resulting in the inability to identify. , and most o...

At present, there are instruments for identifying power-off cables and instruments for identifying live cables on the market. However, in actual use, the actual cables are often placed and pressed together on the spot, and the caliper used by the instrument is often unable to be clamped, resulting in the inability to identify. , and most of the identification receiving parts still use the pointer head to indicate, and the site is prone to failure due to vibration

And often because there is no 220V power supply at the identification site, it is very inconvenient to use
