The invention discloses an endoscope type underground cable fault detection system and a fault analysis method. The endoscope type underground cable fault detection system comprises a sensor integrated probe, data acquisition and transmission equipment and a data processing center, the sensor integrated probe is movably arranged in the underground cable pipeline and is used for acquiring a fault signal of an underground cable; an imaging assembly is arranged at one end of the sensor integrated probe; an integrated sensor assembly is arranged in the sensor integrated probe; the imaging assemblyand the sensor assembly are respectively connected with the data acquisition and transmission equipment through conduction wires; the data acquisition and transmission equipment is connected with thedata processing center and is used for sending the fault signal acquired by the sensor integrated probe to the data processing center; the data processing center is used for obtaining a fault analysis result according to the fault signal. The system has the advantages of being simple in structure, convenient to operate and easy to popularize, internal and external combination can be achieved, cable faults are comprehensively detected through multiple pieces of information, and the detection result is more accurate.
Description
technical field [0001] The invention relates to the technical field of cable fault detection, in particular to an endoscope type underground cable fault detection system and a fault analysis method. Background technique [0002] With the rapid development of urban construction in our country, urban land shortage, traffic pressure, city appearance construction and other reasons, underground cable transmission is widely used in urban power supply and urban construction. Underground cables are often laid in cable trenches, tunnels, pipelines or indoors. The management of underground cables is much more complicated than that of high-altitude cables. It requires accurate information such as the location, direction, and depth of underground cables to facilitate corresponding measurement, laying, overhaul, management and maintenance. In the process of extensive application of underground power cables, various faults often occur, and these faults occurring underground are difficult...
