Basic qhia txog ib tug tub ntxhais cable

Ib leeg tub ntxhais hais txog tsuas muaj ib tus neeg xyuas pib hauv ib txheej txheej rwb thaiv tsev. Thaum qhov hluav taws xob ntau tshaj 35kV, feem ntau ib leeg tub ntxhais cables tau siv, thiab kev sib raug zoo ntawm cov tub ntxhais hlau 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 transformer. Thaum ib lub core cable core hla tam sim no, yuav muaj cov kab hlau nplaum sib nqus hla cov txhuas los yog hlau thaiv txheej, ua rau induced voltage ntawm ob qho kawg.
