Hloov pauvyog ib hom kev ruaj khov voltage hauv Circuit Court, kom muaj kev ruaj ntseg ntawm qhov voltage thiab tam sim no nyob rau hauv Circuit Court, rau lub transformer, nws yog nws tus kheej ib yam khoom siv hluav taws xob, nyob rau hauv ib tug ntau yam ntawm circuits yog ua si lub luag hauj lwm loj thiab ntau yam. ntawm qhov zoo. Lub transformer muaj nws tus kheej voltage thiab tam sim no, thiab feem ntau muaj ob hom transformers ntawm voltage, ib tug yog kab voltage thiab theem voltage. Lawv yog ob qhov sib txawv voltages nyob rau hauv lub transformer, ob qho tib si kev cob cog rua thiab sib txawv, yog li dab tsi yog kev sib raug zoo ntawm lawv?
Cov kab hluav taws xob yog theem voltage peb zaug ntawm lub hauv paus square, uas yog hais txog qhov voltage ntawm cov kab nyob.
Theem voltage yog qhov voltage ntawm txhua theem thiab cov kab nruab nrab. Nws yog qhov voltage ntawm txhua kab nyob thiab kab nruab nrab.
Cov kab hluav taws xob yog hais txog qhov hluav taws xob ntawm cov kab uas ua los ntawm cov cuab yeej peb-theem. Cov theem tam sim no yog hais txog qhov tam sim no ntws los ntawm ib theem kauj ntawm peb-theem ntaus ntawv, thiab theem voltage yog qhov hluav taws xob siv rau cov txheej txheem sib cais. Rau peb-theem plaub-xaim system, theem voltage hais txog qhov voltage ntawm theem kab thiab kab nruab nrab. Rau kev sib txuas ntawm daim duab peb sab, cov kab hluav taws xob sib npaug sib npaug rau theem voltage, thiab cov kab tam sim no sib npaug rau hauv paus ntawm theem tam sim no 3 zaug. Rau lub hnub qub kev sib txuas, cov kab tam sim no sib npaug rau theem tam sim no, thiab cov kab hluav taws xob yog sib npaug li peb npaug ntawm lub hauv paus square ntawm theem voltage. Rau kev siv cov cuab yeej peb-theem, xws li transformers, motors, thiab lwm yam, nws yooj yim dua los ntsuas cov kab tam sim no thiab kab hluav taws xob ntau dua li cov khoom siv uas ntsuas cov theem tam sim no thiab theem voltage, yog li daim ntawv teev npe yog cim nrog kab tam sim no. thiab kab voltage.
Load tam sim no nyob rau theem nrab ntawm lub transformer: kab tam sim no=theem tam sim no, kab voltage ntawm peb theem, theem voltage ntawm tej theem thiab nruab nrab kab.
Nyob rau hauv symmetrical peb-theem Circuit Court, theem voltage los yog kab voltage yuav xam tau, tab sis cov mis yog txawv.
Kab hluav taws xob suav cov qauv:
P = 1.732 * U * I
Cov mis laij lej ntawm theem voltage yog saws:
P=3×U×I
Kev taw qhia txog ob qhov hluav taws xob ntawm lub tshuab hluav taws xob thiab cov txheej txheem suav nrog yog qhia ntawm no. Rau ob qhov voltages ntawm lub transformer, nws yog ib qhov tsim nyog los ua lub luag hauj lwm ntau dua thiab ntau yam zoo los xyuas kom meej qhov stability ntawm lub transformer hloov voltage thiab ua kom muaj kev ruaj ntseg thiab ruaj khov kev lag luam ntawm lub transformer!
