Ib theem ob-xaim ib leeg yog qhia hauv FIG. 2A (daim duab sab saum toj). Cov kab ke no siv 10 kV Ib qho hloov pauv uas nws theem ob ua rau ib theem ib zaug, xws li 120 lossis 240 volts. Cov kab ke no muaj ib kab kub thiab ib kab nruab nrab.
Vim li cas ib ntu thiaj muaj 2 xov tooj?
Ob lub xov tooj kub thiab ib lub xov tooj nruab nrab muab lub zog Txhua lub xov tooj kub muab 120 volts ntawm hluav taws xob. Qhov nruab nrab yog tapped tawm ntawm lub transformer. Ib lub voj voog ob-theem tej zaum muaj tshwm sim vim tias feem ntau lub tshuab rhaub dej, qhov cub thiab lub tshuab ziab khaub ncaws xav tau 240 volts los ua haujlwm.
txhais tau li cas los ntawm ib theem ob lub xaim?
AC fais fab kis tau tus mob yog ib txwm nyob rau ntawm high voltage thiab feem ntau yog 3-theem system. Kev siv ib-theem system yog txwv rau ib-theem hluav taws xob railways. Kev xa hluav taws xob ib zaug yog siv tsuas yog rau qhov luv luv thiab rau qhov tsis tshua muaj hluav taws xob… Ib-theem, 2-xaim system.
Qhov txawv ntawm ib theem thiab 2 theem yog dab tsi?
Ob-theem circuits kuj muaj qhov zoo ntawm qhov tsis tu ncua ua ke lub zog rau hauv qhov zoo tagnrho load, whereas fais fab hauv ib-theem Circuit Court pulsates ntawm twice kab zaus vim xoom hla ntawm voltage thiab tam sim no.
Yog 240V ib theem lossis 2 theem?
240VAC Split Phase yog tsim tawm ib theeminput transformer nrog nruab nrab tapped theem nrab, ua rau cov zis, ib theem hla 240V sab nraud terminals thiab ob 120V ceg nrog theem 180 degree sib nrug.
