DC fais fab mov txhais li cas
DC fais fab mov yog ib qho khoom siv uas tswj qhov voltage thiab tam sim no nyob rau hauv ib lub voj voog. Xws li cov roj teeb qhuav, cov roj teeb cia, DC generators, thiab lwm yam.
DC fais fab mov muaj ob lub electrodes, zoo thiab tsis zoo. Lub peev xwm ntawm qhov zoo electrode yog siab, thiab lub peev xwm ntawm qhov tsis zoo electrode yog tsawg. Thaum ob lub electrodes txuas nrog lub voj voog, qhov sib txawv tsis tu ncua tuaj yeem khaws cia ntawm ob qhov kawg ntawm lub voj voog, yog li tsim ib qho hluav taws xob sab nraud los ntawm qhov zoo electrode mus rau qhov tsis zoo electrode. tsis zoo tam sim no. Lub zog hluav taws xob DC yog lub zog hloov hluav taws xob uas hloov pauv lwm hom hluav taws xob rau hauv hluav taws xob hluav taws xob hluav taws xob hluav taws xob kom tswj tau qhov ntws tsis tu ncua.
Ib qho dej ntws tsis tu ncua tsis tuaj yeem tswj tau los ntawm qhov sib txawv ntawm cov dej, tab sis qhov sib txawv ntawm cov dej tsis tu ncua tuaj yeem tswj tau los ntawm lub twj tso kua dej kom txuas ntxiv xa dej los ntawm qhov chaw qis mus rau qhov chaw siab kom tsim tau cov dej ntws tsis tu ncua. Zoo ib yam li qhov no, electrostatic teb uas tsim los ntawm tus nqi ib leeg tsis tuaj yeem tswj tau qhov tam sim no, tab sis nrog kev pab los ntawm DC fais fab mov, cov nyhuv uas tsis yog electrostatic (xws li "tsis-electrostatic force") tuaj yeem siv los txav cov tus nqi zoo los ntawm qhov tsis zoo electrode nrog lub peev xwm qis dua. Rov qab mus rau qhov zoo electrode nrog lub peev xwm siab dua los ntawm cov khoom siv hluav taws xob los tswj qhov muaj peev xwm sib txawv ntawm ob lub electrodes, yog li tsim kom muaj qhov ruaj khov tam sim no.
Lub zog tsis-electrostatic nyob rau hauv DC fais fab mov yog qhia los ntawm tus ncej tsis zoo mus rau tus ncej zoo. Thaum lub DC fais fab mov txuas nrog rau sab nraud Circuit Court, ib qho tam sim no los ntawm tus ncej zoo mus rau tus ncej tsis zoo yog tsim tawm sab nraud ntawm lub zog hluav taws xob (sab nraud Circuit Court) vim yog kev txhawb zog ntawm lub zog hluav taws xob. Thiab nyob rau hauv lub hwj chim mov (sab hauv Circuit Court), qhov kev txiav txim ntawm tsis-electrostatic quab yuam ua rau tam sim no ntws los ntawm tus ncej tsis zoo mus rau tus ncej zoo, thiaj li hais tias tus khiav ntawm tus nqi tsim ib lub voj voog kaw.
Ib tug yam ntxwv tseem ceeb ntawm lub hwj chim mov nws tus kheej yog lub electromotive quab yuam ntawm lub hwj chim mov, uas yog sib npaug zos rau cov hauj lwm uas tsis yog-electrostatic quab yuam thaum lub unit zoo nqi txav los ntawm tus ncej tsis zoo mus rau lub zoo ncej los ntawm lub sab hauv ntawm lub hwj chim. muab. Thaum lub zog sab hauv ntawm cov khoom siv hluav taws xob tsis txaus ntseeg, nws tuaj yeem txiav txim siab tias lub zog hluav taws xob ntawm lub zog hluav taws xob yog kwv yees li qhov sib npaug ntawm qhov muaj peev xwm sib txawv los yog qhov hluav taws xob ntawm ob tug ncej ntawm lub hwj chim mov.
Txhawm rau kom tau txais DC voltage ntau dua, DC cov khoom siv hluav taws xob feem ntau yog siv hauv series. Lub sijhawm no, tag nrho cov hluav taws xob hluav taws xob yog qhov sib npaug ntawm cov hluav taws xob hluav taws xob ntawm txhua lub zog hluav taws xob, thiab tag nrho cov hluav taws xob sab hauv kuj yog qhov sib npaug ntawm cov hluav taws xob sab hauv ntawm txhua lub zog. Vim muaj kev tiv thaiv sab hauv, nws feem ntau tsuas yog siv tau rau hauv circuits uas yuav tsum tau siv me me tam sim no. Txhawm rau kom tau txais kev siv tam sim no loj dua, DC cov khoom siv hluav taws xob nrog sib npaug electromotive quab yuam tuaj yeem siv ua ke. Lub sijhawm no, tag nrho cov hluav taws xob hluav taws xob yog lub zog hluav taws xob ntawm ib lub zog hluav taws xob, thiab tag nrho cov khoom siv hluav taws xob sab hauv yog tus nqi sib luag ntawm cov khoom siv hluav taws xob sab hauv.
Muaj ntau hom DC fais fab mov. Hauv ntau hom DC fais fab mov, qhov xwm txheej ntawm lub zog tsis muaj hluav taws xob sib txawv, thiab cov txheej txheem ntawm lub zog hloov pauv kuj txawv. Hauv cov roj teeb tshuaj (xws li cov roj teeb qhuav, cov roj teeb cia, thiab lwm yam), lub zog tsis muaj hluav taws xob yog cov tshuaj lom neeg cuam tshuam nrog kev sib cais thiab kev tso tawm ntawm ions. Thaum lub roj teeb hluav taws xob tso tawm, cov hluav taws xob hluav taws xob tau hloov mus rau hauv hluav taws xob hluav taws xob thiab Joule tshav kub hauv cov khoom siv hluav taws xob thermoelectric (xws li cov hlau thermoelectric fais fab mov). Ob peb, semiconductor thermocouple), qhov tsis-electrostatic quab yuam yog cov nyhuv diffusion cuam tshuam nrog qhov sib txawv ntawm qhov kub thiab txias thiab qhov sib txawv ntawm cov electrons. Thaum cov khoom siv hluav taws xob thermoelectric muab lub zog rau cov hluav taws xob sab nraud, lub zog hluav taws xob tau hloov pauv mus rau hauv hluav taws xob ib nrab. Hauv DC lub tshuab hluav taws xob, lub zog tsis yog electrostatic yog electromagnetic induction. Thaum lub tshuab hluav taws xob DC muab lub zog, lub tshuab hluav taws xob hloov mus rau hauv hluav taws xob hluav taws xob thiab Joule tshav kub. Hauv cov cell photovoltaic, lub zog tsis yog hluav taws xob yog qhov ua haujlwm ntawm cov nyhuv photovoltaic. Thaum lub photovoltaic cell yog powered, lub teeb lub zog yog hloov mus rau hauv hluav taws xob zog thiab Joule tshav kub.
