Ntau zaus, txawm nyob hauv cov tsev niaj hnub thiab chav tsev, qhov hluav taws xob hauv hluav taws xob thiab cov tes hauj lwm tuaj yeem dhia hauv qhov txwv loj. Lawm, xws li dhia yuav cuam tshuam rau kev ua haujlwm ntawm cov khoom siv hauv tsev thiab lawv cov kav ntev. Txhawm rau tiv thaiv cov xwm txheej zoo li no, siv lub ntsuas hluav taws xob ntsuas hluav taws xob. Yog vim li cas rau xws li jumps tej zaum yuav yog ib tug hlau tawg los yog sagging, raws li ib tug tshwm sim ntawm cov theem hlau kov lub xoom. Hauv ob peb feeb, txawm tias ua ntej kev tiv thaiv ua haujlwm, khoos phis tawj, tub yees, TVs thiab lwm yam khoom siv hauv tsev tuaj yeem hlawv.
Dab tsi yog qhov ntsuas hluav taws xob ntsuas hluav taws xob? Qhov no yog ib qho khoom siv ntau tus ncej (los ntawm ob mus rau plaub tus ncej), uas yog tsim los txiav tawm thiab ntawm ntau yam khoom siv hluav taws xob (tso cua sov, tub yees, xov tooj cua, thiab lwm yam). Rau kev tswj tsis siv neeg nyob rau hauv voltage xyuas relays, tshwj xeeb programmed microprocessors thiab microcontrollers yog siv, uas kuj yog sensors.qhov kub thiab txias, lub zog tam sim no, qhov hluav taws xob, qhov hluav taws xob poob, thiab tseem muaj lub luag haujlwm rau cov txheej txheem ntawm kev kaw lub cuab yeej thiab lub sijhawm nws yuav siv los tua.
Nws yuav tsum tau qhia meej tias, raws li kev tsim thiab kev siv ntawm kev siv, nyob ntawm tus naj npawb ntawm theem, muaj ib theem thiab peb-theem voltage tswj relays. Peb-theem tiv thaiv cov khoom siv hluav taws xob los ntawm overloads thiab los ntawm qhov muaj peev xwm ntawm kev rub tawm thaum muaj kev ua yuam kev hauv theem ib ntus, ntsuas cov txiaj ntsig zoo ntawm cov theem thiab cov kab hluav taws xob hauv cov hluav taws xob sib txuas nrog ib qho kev sib cais lossis cov khoom sib txuas hauv nruab nrab, tswj cov switching ntaus ntawv ntawm load hwj chim Circuit Court (tshwj xeeb, lub coil ntawm ib tug magnetic oob khab). Ob qho tib si peb-theem voltage xyuas relay thiab ib-theem ntaus ntawv saib xyuas lub zog tiv tauj ntawm lub tshuab hluav taws xob sib nqus lossis contactor ua ntej thiab tom qab qhib thiab kaw lub load, saib xyuas kev noj qab haus huv thiab kev ua haujlwm ntawm cov neeg sib cuag. Lub cuab yeej tua thaum muaj kev kub hnyiab lossis ua rau cov neeg sib cuag. Lub ntsuas hluav taws xob ntsuas hluav taws xob tuaj yeem tig rau tom qab lub sijhawm tus neeg siv tau teev tseg tom qab kev daws teeb meem.
Lub relay ua haujlwm yooj yim heev. Siv cov nyees khawm ntawm rooj plaub, koj yuav tsum teeb tsa qhov chaw pib (qhov siab tshaj plaws thiab qhov tsawg kawg nkaus) qhov ntsuas hluav taws xob uas lub voj voog yuav tawg. Lub neej ntawd qhov tseem ceeb yog 170V thiab 240V. Los ntawm lub neej ntawd, lub relay yuav mus tom qab 0.02 vib nas this. Qhov ceev ceev ntawm kev ua haujlwm no txiav tawm qhov hluav taws xob ua ntej cov khoom siv raug ntaus.thiab cov txheej txheem. Txawm li cas los xij, qhov ntsuas hluav taws xob ntsuas hluav taws xob tsis tiv thaiv hluav taws xob.
Nws muaj ob hom xws li relay: rau ib lub qhov hluav taws xob thiab rau lub tsev feem ntau. Cov tom kawg yog cov feem ntau. Cov khoom siv sib txawv hauv kev thauj khoom thiab kev tso cai tam sim no lub zog.
Thaum xaiv thiab nws tus kheej sib sau ua ke lub ntsuas hluav taws xob ntsuas hluav taws xob, koj yuav tsum ua tib zoo mloog cov lus qhia kev teeb tsa. Los ntawm thiab loj, cov kab kos duab yog tib yam, txawm li cas los xij, nyob ntawm cov chaw tsim khoom, qee cov ntsiab lus yuav txawv.
