Yuav ua li cas teeb meem qhov Low-Voltage Transformer

  1. Txheeb xyuas qhov transformer cov terminals, siv nws daim ntawv lo ua ib qho kev qhia.
  2. Tig ib multimeter rau nws txoj haujlwm VAC.
  3. Kuaj tus transformer cov nkag hluav taws xob nrog rau multimeter , siv cov transformer cov daim ntawv lo raws li daim ntawv qhia davhlau ya nyob twg.
  4. Kuaj tus transformer cov tso zis hluav taws xob nrog rau multimeter .
  5. Disconnect hluav taws xob rau lub transformer .

Kuj paub, koj yuav ua li cas kuaj lub transformer nrog ib tug multimeter?

Rau kuaj lub transformer nrog digital multimeter (DMM), thawj zaug tua hluav taws xob rau hauv Circuit Court. Tom ntej no, txuas cov coj ntawm koj DMM rau cov kab nkag. Siv DMM hauv AC hom los ntsuas qhov transformer thawj.

Tom qab, lo lus nug yog, dab tsi ua rau qis voltage hauv transformer? Feem ntau hauv kev noj qab haus huv transformer lub ntsiab ua rau ntawm tsis tshua muaj hluav taws xob los yog siab hluav taws xob yog vim hluav taws xob Kev hloov pauv hauv HT tuaj hluav taws xob uas yog pub nyob rau hauv HT sab ntawm transformer . Koj tuaj yeem kov yeej qhov no los ntawm kev hloov pauv cov kais dej ntawm transformer tap changer.

Kuj tseem paub, qhov hluav taws xob qis hluav taws xob puas tuaj yeem ua phem?

Feem ntau transformers yuav Tsis feem ntau tsis luv rau hauv av, muaj ntau qhov rwb thaiv tsev nyob ntawd. Lawv tsis shorted los yog qhib lem ntau ntau. Qhov feem ntau "spontaneous" tsis ua hauj lwm ntawm a transformer yog qhov tshwm sim ntawm deterioration ntawm enamel rwb thaiv tsev ntawm cov hlau, feem ntau tshwm sim los ntawm cov cua kub ntau dhau.
