Description

technical field [0001] The invention relates to the technical field of high-voltage cable operation monitoring, in particular to a high-voltage cable line operation monitoring system. Background technique [0002] When the metal sheath of a single-core cable and the cable core pass through an alternating current, the magnetic force lines will be hinged, causing a high induced voltage at both ends. Therefore, appropriate grounding measures must be taken to keep the induced voltage within a safe voltage range. , but no matter what grounding method is used, once the grounding system is damaged, such as the cross interconnection line is stolen or the direct grounding point is not effectively grounded, the outer sheath of the cable will be broken down and the discharge will continue at the breakdown point, causing The temperature of the outer sheath of the cable rises and even causes a fire. In order to ensure the safety of the high-voltage cable operation, it is necessary to mon...

[0002] When the metal sheath of the single-core cable and the cable core pass through the AC current, the magnetic field lines will be hinged, causing a high induced voltage at both ends. Therefore, appropriate grounding measures must be taken to keep the induced voltage within a safe voltage range. , but no matter what grounding method is used, once the grounding system is damaged, such as the crossover interconnection line is stolen or the direct grounding point is not effectively grounded, the outer sheath of the cable will be broken down and the discharge will continue at the breakdown point, causing The temperature of the outer sheath of the cable rises and even causes a fire. In order to ensure the safety of the high-voltage cable operation, it is necessary to monitor the operating status of the high-voltage cable

[0003] At present, the operation monitoring of high-voltage cable lines can only detect the abnormal fault data in the operation of high-voltage cables, and analyze and warn the abnormal fault data. Safety measures are taken in the running state, and the initial location of the abnormal fault data cannot be tracked, so that the monitoring and management personnel cannot find the abnormal fault point of the high-voltage cable at the first time, thus delaying the best emergency remedial time
