Kuaj xyuas lub cev muaj zog winding tsis kam lossis ohms nyeem siv lub tshuab hluav taws xob lossis ohmmeter rau theem mus rau theem davhlau ya nyob twg (U rau V, V rau W, W rau U). Lub ohms nyeem rau txhua qhov cua yuav tsum yog tib yam(los yog ze li qhov qub). Nco ntsoov tias peb theem muaj qhov sib npaug los yog ze li ntawd!
pes tsawg ohms yuav tsum muaj 3 theem lub cev muaj zog?
Cov windings (tag nrho peb nyob rau hauv peb-theem lub cev muaj zog) yuav tsum nyeem qis tab sis tsis xoom ohms. Lub tshuab me me, qhov kev nyeem ntawv no yuav siab dua, tab sis nws yuav tsum tsis txhob qhib. Nws feem ntau yuav qis txaus (hauv qab 30 Ω) rau qhov ntsuas qhov txuas ntxiv mus rau suab.
Lub cev muaj zog yuav tsum nyeem theem mus rau theem li cas?
Kev nyeem ntawv yuav tsum yog ntawm 0.3 txog 2 ohms. Yog tias nws yog 0, muaj luv. Yog tias nws tshaj 2 ohms los yog infinite, muaj qhov qhib. Koj tseem tuaj yeem qhuav qhov txuas thiab rov sim dua kom tau txais cov txiaj ntsig raug ntau dua.
Yuav ua li cas koj thiaj paub yog tias lub cev muaj zog 3 theem tsis zoo?
Kaws tag nrho peb lub xov tooj ib leeg T1, T2, T3 (tag nrho peb theem) rau hauv av xaim. Kev nyeem ntawv yuav tsum yog qhov kawg. Yog tias nws xoom lossis nyeem ib qho txuas ntxiv ntawm tag nrho, ces muaj teeb meem nrog lub cev muaj zog lossis cable. Yog hais tias nws yog ncaj qha mus rau lub cev muaj zog thiab disconnect los ntawm cable thiab xyuas lub cev muaj zog thiab lub cable cais.
Puas muaj pes tsawg ohms yuav tsum muaj ib theem lub cev muaj zog?
Lub cev muaj zog yuav tsum nyeem tsawg dua 0.5 ohms. Txhua tus nqi ntau dua 0.5 ohms qhia teeb meem nroglub cev muaj zog. Rau ib theem motors, qhov kev cia siab voltage yog hais txog 230V los yog 208V nyob ntawm seb koj puas siv lub UK los yog America voltage system.
