Sib piv cov high-voltage cables thiab low-voltage cables, cov khoom ntawm sab hauv mus rau sab nrauv muaj xws li: tus neeg xyuas pib, rwb thaiv tsev, sab hauv sheath, muab tub lim (tsim armor), thiab txheej rwb thaiv tsev. Nws yog tsuas yog siv los xa cov hluav taws xob hluav taws xob, thiab feem ntau yog siv rau hauv kev tswj xyuas hluav taws xob hluav taws xob hluav taws xob, lub teeb liab ntawm lub tswb hluav taws xob tsis siv neeg, thiab kev ua haujlwm ntawm cov kab sib kis.
Raws li cov kev cai, qee qhov hluav taws xob AC fais fab kis tau zoo siv peb-theem peb-xaim, thiab peb cov xov hlau yog peb-theem hluav taws xob los ntawm cov kauj ruam-up transformer. teeb pom kev zoo.
Lub teeb pom kev zoo kuj xav tau ib txoj kab xoom, uas tau txais los ntawm kev sib txuas hnub qub thaum tus neeg siv lub davhlau ya nyob twg tau nqis los. Ntawd yog, peb-theem high-voltage hluav taws xob txuas nrog lub taub hau ntawm peb-theem transformer winding, thiab peb tails txuas ua ke los ua ib txoj kab xoom. kuv lub teb chaws 10KV, 110KV, 220KV. 500KV high-voltage kis tau tus mob tsis muaj kab nruab nrab, vim hais tias cov qib voltage no tsis tuaj yeem siv ncaj qha rau cov khoom siv. Thaum qhov hluav taws xob theem siab tshaj 10kV, cov kab nruab nrab thiab cov kab nyob ua ke ua ib theem hluav taws xob, thiab tib lub sijhawm ua raws li qhov nruab nrab hauv av (ua haujlwm hauv av) ntawm cov khoom siv khiav haujlwm. .
Txawm li cas los xij, thaum qhov hluav taws xob ntau tshaj 35KV, feem ntau ntawm cov tub ntxhais cables siv tau. Kev sib raug zoo ntawm nws cov tub ntxhais thiab cov hlau thaiv txheej tuaj yeem suav tias yog kev sib raug zoo ntawm cov kauj thiab cov tub ntxhais hlau hauv thawj winding ntawm lub transformer. Thaum ib leeg-core cable core hla tam sim no, nws yuav Muaj cov kab sib nqus ntawm cross-linked aluminium cladding thiab hlau shielding txheej kom induced voltage tshwm ntawm ob hnub. Ib leeg-ntxhais cables muaj qhov tsis zoo ntawm lwm cov cables, thiab lawv tuaj yeem tiv taus qhov hluav taws xob ntau dua.
