Transformer kev ua haujlwm suav nrog cov hluav taws xob siab thiab cov hluav taws xob siab; yog li ntawd, kev tswj kev nyab xeeb yog qhov tseem ceeb. Ua ntej kev teeb tsa lossis kev saib xyuas, chav tsev yuav tsum tau ua kom tag nrho de-energized, paub tseeb tias tuag, thiab hauv av los tiv thaiv hluav taws xob raug mob los ntawm qhov seem hluav taws xob lossis kev sib tsoo re-energization. High- cov khoom siv hluav taws xob xav tau cov cim ceeb toom pom tseeb thiab yuav tsum tau ua los ntawm cov kws tshaj lij los tiv thaiv cov neeg ua haujlwm tsis raug cai los ntawm kev sib cuag nrog cov khoom nyob. Thaum lub sijhawm ua haujlwm, cov ntsuas tseem ceeb xws li qhov kub thiab txias, qib roj, thiab cov txheej txheem rwb thaiv tsev yuav tsum tau saib xyuas. Rau cov roj-immersed transformers, teeb meem xws li roj to, txawv txav kub nce, los yog suab nrov txawv txawv yuav qhia tau hais tias nyob rau hauv lub faults, yuav tsum tau kaw tam sim ntawd rau kev soj ntsuam. Transformer roj pab ob qho tib si insulating thiab txias zog; Yog li, roj degradation los yog kev sib kis ncaj qha cuam tshuam rau kev ua haujlwm nyab xeeb. Tsis tas li ntawd, cov rwb thaiv tsev tiv thaiv yuav tsum tau sim tsis tu ncua los tiv thaiv dielectric puas lossis luv luv - cov xwm txheej hauv Circuit Court tshwm sim los ntawm rwb thaiv tsev laus.
Kev tu txhua hnub yuav tsum suav nrog kev tiv thaiv hluav taws thiab tawg, tshwj xeeb tshaj yog thaum lub sijhawm ua haujlwm siab -. Qhov chaw nyob ib puag ncig lub transformer yuav tsum zoo - qhov cua thiab khaws cia tsis muaj cov khoom siv hluav taws xob, thiab cov hluav taws kub tsim nyog - yuav tsum muaj cov cuab yeej tua hluav taws. Lub tshuab hluav taws xob loj loj yuav tsum muaj kev tiv thaiv kev tiv thaiv- xws li kev tiv thaiv overcurrent, kev tiv thaiv kev sib txawv, thiab qhov kub thiab txias -tswj lub tswb ntsuas- kom txiav tawm lub hwj chim tam sim ntawd thaum muaj qhov tsis zoo thiab tiv thaiv kom muaj kev sib tsoo. Ua ke, cov kev ntsuas no ua kom muaj kev nyab xeeb thiab ruaj khov ntawm kev hloov pauv hauv lub zog hluav taws xob.
