Fais fab transformers yog cov khoom tseem ceeb hauv ntau qhov kev lag luam, nrog rau kev tsim hluav taws xob thiab kev xa tawm, kev tsim khoom lag luam, thiab kev sib txuas lus. Lawv yog lub luag haujlwm rau kev nce lossis nqis qis ntawm cov hluav taws xob hluav taws xob, tso cai rau nws mus rau kev sib kis mus ntev lossis siv los ntawm ntau yam khoom siv. Txawm li cas los xij, zoo li lwm yam khoom siv, lub zog hloov hluav taws xob xav tau kev saib xyuas tsis tu ncua kom ntseeg tau tias lawv ua haujlwm tau zoo thiab tiv thaiv kev ua tsis tiav uas tuaj yeem ua rau raug nqi poob qis thiab kho.
Ib qho ntawm cov cuab yeej tseem ceeb hauv kev tu transformer yog lub transformer ohmmeter. Cov cuab yeej no yog siv los ntsuas qhov tsis kam ntawm transformer windings thiab kuaj xyuas txhua yam teeb meem. Los ntawm kev ntsuas qhov tsis kam ntawm winding, cov kws tshaj lij tuaj yeem txheeb xyuas cov teeb meem xws li rwb thaiv tsev puas, luv Circuit Court, lossis kev sib txuas xoob. Cov teeb meem no tuaj yeem daws tau ua ntej lawv ua rau muaj kev puas tsuaj loj dua lossis ua rau lub tshuab hluav taws xob tsis ua haujlwm.
Kev siv cov transformer ohmmeters tsis tu ncua ua ib feem ntawm kev saib xyuas ib txwm tuaj yeem pab txuas ntxiv lub neej ntawm transformer thiab txhim kho nws cov kev ua tau zoo. Los ntawm kev kuaj xyuas thiab kho cov teeb meem me me ua ntej lawv nce, cov kws tshaj lij tuaj yeem tiv thaiv qhov tsis tsim nyog hnav thiab tsim kua muag ntawm lub tshuab hloov pauv thiab txo qhov kev pheej hmoo ntawm kev kho loj lossis hloov pauv.
Muaj ntau hom transformer ohmmeters muaj nyob rau hauv kev ua lag luam, nrog rau cov qauv siv tes ua rau kev sim teb thiab ntau dua qauv rau kev kuaj sim. Qee cov qauv tsim tshwj xeeb rau kev ntsuas qhov tsis kam ntawm high-voltage transformers, thaum lwm tus yog tsim rau me me transformers lossis lwm yam khoom siv hluav taws xob.
Ntxiv nrog rau kev saib xyuas tsis tu ncua, transformer ohmmeters kuj tseem siv tau thaum lub sijhawm teeb tsa thiab ua haujlwm kom ntseeg tau tias lub tshuab hloov pauv ua haujlwm raug thiab nyab xeeb. Piv txwv li, lawv tuaj yeem siv los txheeb xyuas qhov kev tiv thaiv ntawm cov windings thiab xyuas kom meej tias lawv txuas nrog kom zoo, nrog rau txhawm rau txheeb xyuas cov kev phom sij xws li cov teeb meem hauv av lossis cov xwm txheej overcurrent.
Transformer ohmmeters yog cov cuab yeej tseem ceeb hauv kev saib xyuas thiab kev ua haujlwm ntawm lub zog transformers. Los ntawm kev siv cov cuab yeej no tsis tu ncua, cov kws tshaj lij tuaj yeem txheeb xyuas thiab daws cov teeb meem muaj peev xwm ua ntej lawv dhau los ua cov teeb meem loj, ua kom ntseeg tau thiab ua haujlwm tau zoo ntawm lub tshuab hluav taws xob dhau nws lub neej.
