Description
Technical field
Present technique relates to power cable transmission of electricity security fields, road.The device systems of one cover monitoring power cable transmission of electricity road safety especially is provided.
Background technology
Power cable adopts the cable of solid insulation more, causes that the reason of cable generation deterioration is more, current weigherization, hot deterioration is arranged, chemical deterioration, mechanical deterioration etc.For high-tension cable (35kV and more than), all are single core cables, the cable core of single core cable makes its two ends induced voltage occur through the magnetic line of force and the protective metal shell interlinkage that alternating current produces, so need take grounding measures.Generally, the protective metal shell of short-term road single core cable adopts the direct ground connection of an end and the other end through the gap or the mode of protective resistance ground connection; Long transmission line single core cable protective metal shell then adopts the earthing mode at the cross interconnected two ends of three-phase segmentation; (cross interconnected connection equivalence is delta connection to reduce circulation that cable metal sheath produces; Ground connection circulation major part is cancelled out each other, about the less about 1A of the circulation of generation).If cable cover(ing) is because of multipoint earthings that is damaged such as chemistry, machinery even mouse insect pests; To form bigger circulation at its screen layer; Can reach the 50%-90% of principal current when serious, just tens of amperes even ampere up to a hundred, loss is very big; Even the cable blast can take place, influence the safe operation of electric system.Behind the protective metal shell multipoint earthing; The amplitude that circulation increases changes with the variation of line impedance; Variation with the ground connection situation changes in view of the variable quantity of circulation, through on-line monitoring circulation value and relative variation, measures deterioration state; Judge whether cable insulation can continue operation, and this is very important for the safe operation that guarantees electrical network.
Cable is an important component part of electric system, and the various protection monitorings of cable conductor are more, but the monitoring of the protective metal shell multipoint earthing of cable is not very desirable.
Summary of the invention
In order to address the above problem, the utility model provides cable metal sheath grounding current and cable temperature monitoring system.
The utility model monitoring system comprises signal collection part 6, signal Processing partly; Described signal collection part 6 comprises acquisition controller 3, transmission control unit (TCU) 4, signal projector 5; Signal Processing partly comprises signal receiver 7, gateway system 8, central processing platform 9, client 10; Wherein, acquisition controller 3 is connected with transmission control unit (TCU) 4, and transmission control unit (TCU) 5 is connected with signal projector 5; Signal receiver 7 is connected with gateway system 8, and gateway system 8 is connected with central platform 9, and central platform 9 is connected with client 10.
Described acquisition controller 3 is provided with temperature sensor 1 and current sensor 2, and described temperature sensor 1 is close on the cable 12, and current sensor 2 is a mutual inductor, is arranged on the cable metal sheath earthing cable 11.
The beneficial effect of the utility model is: the successful monitoring power cable ruuning situation of ability, and the running temperature of cable and the electric current of earthing cable are monitored and analyzed, and the client that unusual monitoring information is transferred to the utility model will occur, and early warning.
