Nyob rau hauv lub hwj chim transformers, lub high-voltage (HV) winding yog feem ntau muab tso rau lub low-voltage (LV)tshuab winding. Qhov no yog vim HV winding muaj qhov muaj peev xwm ntau dua li LV winding, thiab muab tso rau sab saum toj yuav pab txo qis kev pheej hmoo ntawm hluav taws xob tawg ntawm cov windings.
Thaum lub tshuab hluav taws xob muaj zog, HV winding tsim hluav taws xob muaj zog, uas tuaj yeem ionize cov huab cua ib puag ncig thiab tsim corona tawm. Qhov kev tso tawm corona no tuaj yeem ua rau muaj hluav taws xob tawg ntawm cov windings yog tias HV winding muab tso rau hauv qab ntawm LV winding. Los ntawm kev tso HV winding rau saum, qhov kev ncua deb ntawm cov windings yog nce, uas txo qhov kev pheej hmoo ntawm hluav taws xob tawg.
Tsis tas li ntawd, muab HV winding rau sab saum toj tuaj yeem pab txhim kho qhov txias ntawm transformer. Txij li HV winding ua kom muaj cua sov ntau dua li LV winding vim qhov siab dua tam sim no, muab tso rau sab saum toj tso cai rau kom muaj cua sov zoo dua, vim tias cov cua sov nce mus rau sab saum toj ntawm lub transformer.
Zuag qhia tag nrho, tso HVcoil winding tshuabnyob rau sab saum toj ntawm LV winding yog ib qho kev coj ua hauv kev tsim hluav taws xob hloov hluav taws xob los txo qhov kev pheej hmoo ntawm hluav taws xob tawg thiab txhim kho kev ua kom txias.
