Transformer yog kev ua haujlwm tsis tu ncua ntawm cov cuab yeej zoo li qub, ua haujlwm tau zoo dua, tsis muaj txoj hauv kev tsis ua tiav.Tab sis vim tias feem ntau ntawm cov hloov pauv tau teeb tsa sab nraum zoov, thiab cuam tshuam los ntawm kev ua haujlwm ntawm lub nra thiab cuam tshuam ntawm lub zog hluav taws xob luv Circuit Court txhaum, txheej txheem ntawm kev ua haujlwm, muaj kev zam txhua yam kev ua txhaum thiab qhov xwm txheej txawv txav.
1. Cov ua tsis raug thiab qhov txawv txav ntawm cov hloov pauv
2. Kev teeb tsa ntawm kev tiv thaiv kev hloov pauv
3. Tsis tiv thaiv hluav taws xob
(1) Kev tiv thaiv roj
(2) Kev tiv thaiv siab
(3) Kub thiab tiv thaiv qib roj
(4) Txias tag nrho nres nres
4. Kev tiv thaiv sib txawv
(1) Magnetizing inrush tam sim no ntawm kev hloov pauv
(2) Lub hauv paus ntsiab lus ntawm kev sib haum xeeb thib ob
(3) Kev tiv thaiv sib txawv nrawm-tawg
Qhia cov no luv luv ntawm qhov kev tiv thaiv tseem ceeb ntawm tus hloov pauv, thiab txuas ntxiv qhia kev tiv thaiv kev tiv thaiv ntawm tus hloov pauv. Muaj ntau hom kev tiv thaiv kev teeb tsa thaub qab rau cov hloov pauv. Nov yog cov lus qhia luv luv rau ob hom kev tiv thaiv kev tiv thaiv, kev tiv thaiv overcurrent thiab kev tiv thaiv hauv av ntawm kev hloov pauv.
1. Kev tiv thaiv overcurrent nrog kev rov kaw siab
2. Kev tiv thaiv av ntawm transformer
Kev tiv thaiv thaub qab rau kev ua txhaum luv luv ntawm kev hloov pauv loj thiab nruab nrab feem ntau suav nrog: xoom ntu ntu tiv thaiv tam sim no, xoom ntu sib tiv overvoltage tiv thaiv, tiv thaiv qhov sib txawv, thiab lwm yam. taw tes.
(1) Lub ntsiab lus nruab nrab yog ncaj qha rau hauv av
(2) Lub ntsiab lus nruab nrab tsis yog hauv paus
(3) Lub ntsiab lus nruab nrab yog hauv av los ntawm qhov sib kis tawm
Lub tshuab hluav taws xob ultra-high voltage yog txhua lub tshuab hluav taws xob ib nrab, thiab cov rwb thaiv tsev hauv av ntawm qhov nruab nrab taw tes tsis muaj zog dua li lwm qhov. Qhov nruab nrab cov ntsiab lus rwb thaiv tsev tau yooj yim tawg. Yog li ntawd, kev tiv thaiv kis yuav tsum tau teeb tsa.
Kev ua haujlwm ntawm kev tiv thaiv qhov sib txawv yog txhawm rau tiv thaiv kev nyab xeeb rwb thaiv tsev ntawm qhov nruab nrab ntawm qhov tsis sib xws nruab nrab ntawm qhov hloov pauv.
Kev tiv thaiv qhov sib txawv tau pom los ntawm kev siv qhov sib txawv tam sim no 3I0 ntws los ntawm qhov nruab nrab ntawm qhov hloov pauv thiab qhib qhov hluav taws xob qhov hluav taws xob 3U0 ntawm lub busbar PT raws li tus qauv.
Yog tias qhov nruab nrab ntawm qhov ua txhaum nce mus rau qhov chaw, qhov sib txawv tau tawg thiab qhov sib txawv loj tam sim no 3I0 tau tsim. Lub sijhawm no, kev tiv thaiv qhov sib txawv tau qhib thiab lub tshuab hluav taws xob raug txiav tawm tom qab ncua sijhawm. Ib qho ntxiv, thaum muaj kev ua txhaum hauv av tshwm sim hauv qhov system, qhov nruab nrab qhov taw qhia tau raug tsau thiab kev tiv thaiv xoom ntu ntawm kev hloov pauv tau ua haujlwm, thiab lub ntsiab lus nruab nrab yog hauv av ua ntej. Tom qab lub kaw lus poob lub hauv paus, yog tias tseem muaj qhov ua txhaum, qhib qhov hluav taws xob qhov hluav taws xob 3U0 ntawm lub busbar PT yuav loj heev, thiab kev tiv thaiv qhov sib txawv tseem yuav ua haujlwm nyob rau lub sijhawm no.
