specific Embodiment
[0026] The overhead cables are carried between the cable towers 10. When their own weight and external environment influence, when a part of the outer sheath 5 is damaged, the outer filling liquid 9 will leak from the compartment; if the entire layer of the outer sheath 5 is completely If it is disconnected, the outer filling liquid 9 in all compartments leaks; and when it develops to the inner side, when the separating insulating layer 4 is damaged or completely disconnected, the leakage of the inner filling liquid 8 is the same as that of the outer filling liquid 9; while the outer The hydraulic pressure sensor 15 and the inner hydraulic pressure sensor 16 can timely feed back the detected leakage of filling fluid to the remote main processing unit 11, and the remote main processing unit 11 performs rapid analysis and judgment, and grades and effectively resolves cable accidents.

The invention discloses a fluid pressure sensing and transmission-based multilevel detection type cable, and relates to the field of cable detection structures. The fluid pressure sensing and transmission-based multilevel detection type cable comprises an inner conductor, a packing medium, an inner insulation layer, a separation insulation layer, an outer sheath, an inside fluid separation section, an outside fluid separation section, an inside packing fluid, an outside packing fluid, a cable tower, a remote main processing unit, an inner analysis unit, an outer analysis unit, a cable joint box, an outside hydraulic sensor and an inside hydraulic sensor. According to the fluid pressure sensing and transmission-based multilevel detection type cable, the outside hydraulic sensor and the inside hydraulic sensor are utilized to carry out hydraulic detection on the packing fluids in the cable insulation layers, and transmit the detection result to the remote main processing unit to carry out analysis, so as to rapidly position the damaged cable sections; two layers of packing fluid structures are additionally arranged at the outer layer of the cable, and the packing fluids are separated into four sections, so that the depths and angle ranges of the damages can be rapidly analyzed during damage analysis and the cable damage levels can be analyzed more accurately.
Description
technical field [0001] The invention relates to the field of cable detection structures, in particular to a multi-stage detection cable based on liquid pressure sensing and transmission. Background technique [0002] Cables can be divided into power cables, communication cables and control cables according to their uses. Compared with overhead lines, the advantages of cables are that the insulation distance between lines is small, the space occupied is small, the space above the ground is not occupied by laying underground, it is not affected by the pollution of the surrounding environment, the reliability of power transmission is high, and it does not interfere with personal safety and the surrounding environment Small. But the cost is high, the construction and maintenance are more troublesome, and the manufacture is also more complicated. Therefore, cables are mostly used in densely populated and grid-dense areas and places with heavy traffic; when laying across rivers,...
