Comprehensive detection system for underground cables

Abstract

The invention relates to an underground cable comprehensive detection system which is technically characterized by comprising a high-power signal emission device, a loading coil, a signal receiving device and a display recording device, wherein an output end of the high-power signal emission device is connected with the loading coil, the loading coil is installed on a cable to be detected in a sleeved mode and produces radio-frequency signals under control of the high-power signal emission device, voltage displaying is carried out and voltage is outputted to the display recorder device after the signal receiving device receives the radio-frequency signals, and the display recording device carries out calculation on the received voltage and then outputs detection results. According to the underground cable comprehensive detection system, design is reasonable, the direct digital frequency synthesis technology is utilized, the high-power radio-frequency power emission technology is combined, control precision of frequency is higher, the frequency is more stable, meanwhile double receiving antennas are utilized to be matched with a receiving circuit, display is carried out on the display recording device, detecting difficulty is reduced, accuracy of detection is improved, and labor intensity of detecting staff is lightened.

Description

technical field [0001] The invention belongs to the technical field of cable detection, in particular to an underground cable comprehensive detection system. Background technique [0002] In the power transmission system, many power cables are buried underground, and these cables may pass through complex terrain or across oceans. When maintaining underground cables, it is necessary to accurately locate, track, identify and sound the underground cables. Although there are line diagrams and a certain number of marks drawn during the construction process, there are inevitably some ambiguities, unknown directions, and Inaccurate places will not only cause a lot of waste of manpower and material resources during the excavation process, but also cause low efficiency, and there will also be digging errors and heavy losses. The existing underground cable detection devices generally have problems such as small detection range, low precision and inconvenient operation. Contents of ...
