Hauv cov kab sib kis ntawm lub zog hluav taws xob, cov fais fab tsim tawm txawm tias tsis muaj kev thauj khoom ntxiv vim muaj kab inductance. Cov kev sib tw ua kom muaj zog yuav cuam tshuam rau cov voltage poob ntawm txoj kab. Txhawm rau tswj cov hluav taws xob ruaj khov ntawm ntau cov nodes ntawm lub zog nyiaj ntsuab thiab cov koob yees duab hluav taws xob ua kom zoo thiab cov khoom siv hluav taws xob ua kom muaj zog lossis nqus tau lub zog ua kom raws sijhawm.
Lub zog tiv thaiv tsis tuaj yeem tsuas yog khaws cia thiab tso tawm lub zog ruaj khov, tab sis kuj tseem txhim kho lub zog thiab lub zog hluav taws xob kev them nyiaj.
1 lub hwj chim muaj hwj chim
Lub zog muaj peev xwm (PF) yog qhov tseem ceeb hauv AC circuits, uas qhia txog qhov sib piv ntawm lub zog siv hluav taws xob (tseem muaj lub zog siv hluav taws xob) kom pom meej lub zog hauv Circuit Court hauv Circuit Court. Nyob rau hauv ib qho AC Circuit Court, lub zog muab los ntawm lub zog hluav taws xob rau lub nra muaj xws li lub zog thiab muaj zog. Lub zog nquag yog hais txog lub zog siv tiag tiag rau kev ua haujlwm, erverting hluav taws xob thiab hluav taws xob siv los tsim cov hlau sib nqus thiab hluav taws xob, tab sis tsis ua haujlwm sab nraud. Lub zog pom tseeb yog lub vector suav ntawm cov nquag muaj zog thiab reactive zog, uas tus nqi yog sib npaug rau cov khoom ntawm voltage thiab tam sim no. Lub zog siv hluav taws xob tuaj yeem suav los ntawm kev faib cov khoom siv hluav taws xob nquag los ntawm lub zog pom tseeb.
Qhov kev qhia ua lej yog: Factor factor=Lub Zog Muaj Zog \/ Pom Zoo
Thaum lub zog siv hluav taws xob yog tsawg, muaj qhov loj dua tam sim no nyob rau hauv Circuit Court mus xa cov zog qub, uas txhais tau tias nce hauv txoj kab. Los ntawm kev nce lub hwj chim, tam sim no nyob rau hauv kab tuaj yeem txo, yog li txo cov kab tsis kam thiab txhim kho kev siv zog thiab kev siv hluav taws xob.
2 lub hauv paus ntsiab lus ntawm reactive fais fab nyiaj rau lub zog cia khoom zog
1. Lub tswv yim ntawm kev siv fais fab
Refore zog yog hais txog lub zog nqus los ntawm ib qho hluav taws xob lossis sib nqus ntawm ib feem ntawm ib feem ntawm ib feem ntawm AC Circuitance nyob rau hauv ib feem ntawm AC Circuitance ntawm ib feem ntawm AC Circuitance Qhov nruab nrab lub zog thaum lub voj voog tag nrho yog xoom, tab sis kev sib pauv ntawm lub zog thiab cov ntsiab lus (inductance, capacitanced). Chav tsev ntawm cov hluav taws xob cuam tshuam yog var lossis kvar.
2. Xub tshuaj ntawm reactive fais fab nyiaj rau lub zog khoom tshuab
Lub zog hluav taws xob tuaj yeem ua kom muaj kev cuam tshuam cov tshuaj tiv thaiv hluav taws xob rau lub zog hluav taws xob los ntawm kev tswj hwm nws cov khoom tawm ntawm cov nquag thiab muaj zog.
Thaum cov hluav taws xob reactive hauv lub zog hluav taws xob tsis txaus, lub zog cia system tuaj yeem tso cov zog hluav taws xob ntawm lub zog hluav taws xob; Thaum muaj ntau dhau kev hloov fais fab hauv lub zog system, lub zog cia lub zog tuaj yeem nqus tau lub zog hluav taws xob kom tiv thaiv lub zog hluav taws xob los ntawm kev ua siab dhau. Tshwj xeeb, thaum muaj qhov tseem ceeb siv rau lub zog hluav taws xob hauv lub zog ua haujlwm, txhim kho kev ua haujlwm ntawm lub zog ua haujlwm thiab kev poob qis kab poob.
Thaum lub voltage deviates los ntawm cov nqi nyob hauv lub zog, tswj hwm kev ruaj khov, thiab tiv thaiv kev puas tsuaj rau lub zog hluav taws xob ua rau muaj hluav taws xob siab lossis qis dua. Piv nrog cov tshuaj ntsuab reactive xws li cov neeg siv hluav taws xob zoo li qub, thiab lwm yam.
3. Lub zog cia Inverter muaj nuj nqi
Lub Zog Cia Inverter muaj plaub lub lag luam ua haujlwm, uas tuaj yeem ua kom tiav cov zis lossis muaj peev xwm nqus tau cov haujlwm thiab cov hluav taws xob kev ua haujlwm thiab cov hluav taws xob kev tswj hwm. Cov nyiaj kho hluav taws xob reactive thev naus laus zis muaj qhov zoo ntawm cov tshuab ceev ceev, thiab yog qhov tsim nyog txuas ntxiv ntawm lub zog tshiab thiab muaj zog hluav taws xob. Lub zog hluav taws xob tshiab yeej los ntawm lub zog tshiab ua lub luag haujlwm tseem ceeb dua hauv kev muab cov nyiaj cuam tshuam ntsig txog kev siv hluav taws xob rau lub zog cia.
3 Resive Fais Npas Them Nyiaj Ua Haujlwm rau Lub Zog Cia Khoom
(1) Saib xyuas cov xwm txheej ntawm lub zog hluav taws xob: ua ntej, los ntawm kev saib xyuas cov tsis muaj zog, thiab muaj zog nkag siab txog cov haujlwm tam sim no ntawm lub zog hluav taws xob tuaj yeem tau txais;
