Siab - ceg delta (tseem hu ua wild- ceg , lus ceg , tug ceg , siab - ceg , txiv kab ntxwv- ceg , los yog liab- ceg delta) yog ib hom kev pabcuam hluav taws xob sib txuas rau peb-theem hluav taws xob fais fab kev teeb tsa. Lub hwj chim peb-theem txuas nrog hauv delta configuration, thiab qhov chaw nruab nrab ntawm ib theem yog grounded.

Xav txog qhov no, txhais ceg siab siv rau dab tsi?

Nws yog feem ntau siv rau muab ob lub 120V AC thiab ib qho 208V AC Circuit Court nrog rau qhov nruab nrab txawm hais tias lwm qhov hluav taws xob muaj peev xwm ua tau nyob ntawm theem mus rau theem voltage ntawm theem nrab windings.

Tsis tas li ntawd, puas yog 120 208 volt peb theem muaj ib ceg siab? Peb Theem Plaub Hlau Delta Kuj hu ua a siab - ceg los yog qus- ceg delta system. Siv rau hauv cov chaw tsim khoom qub nrog feem ntau peb - theem lub cev muaj zog thiab qee qhov 120 hluav taws xob ib leeg- theem teeb pom kev thiab ntsaws loads. Theem B, ua siab los yog qus ceg , yog tsis siv li cov hluav taws xob rau nruab nrab yog 208 hluav taws xob.

Raws li, theem twg yog tus ceg siab yuav tsum yog?

Cov Lus Qhia. Cov siab - ceg los yog theem nrog rau qhov siab dua voltage raws li ntsuas rau nruab nrab tau ib txwm raug xaiv " Theem B». Kev hloov pauv rau 2008 NEC tam sim no tso cai rau cov siab ceg ntawm plaub-xaim peb- theem delta kev pabcuam yuav tsum tau sau npe ua "C" theem es tsis txhob "B" theem.

415v txhais li cas?

Peb-theem hluav taws xob yog ib hom kev sib hloov tam sim no hluav taws xob tsim hluav taws xob, kev sib kis, thiab kev faib tawm. Nws yog ib hom polyphase system thiab yog txoj kev siv feem ntau siv los ntawm cov phiaj xwm hluav taws xob thoob ntiaj teb los hloov lub zog. Nws yog kuj tseem siv tau rau lub zog loj motors thiab lwm yam hnyav loads.
