Cov ntaub ntawv tseem ceeb txog DC tswj fais fab mov
Cov khoom siv hluav taws xob uas muab DC lub zog ruaj khov rau kev thauj khoom. Lub zog ntawm DC stabilized fais fab mov yog qhov pib AC fais fab mov. Lub regulator lub DC tso zis voltage tseem nyob ruaj khov thaum lub AC mov voltage los yog load kuj hloov. Tau kawg, raws li cov khoom siv hluav taws xob tsim los ntawm kev ua haujlwm siab thiab kev ruaj ntseg siab, DC cov khoom siv hluav taws xob ruaj khov tau muab cov kev xav tau siab dua rau cov khoom siv hluav taws xob.
1. Tus nqi hluav taws xob tso zis tuaj yeem teeb tsa arbitrarily hauv qab tus nqi tso zis voltage thiab nws yuav ua haujlwm ib txwm.
2. Tus nqi tam sim no ruaj khov ntawm cov zis tam sim no tuaj yeem teeb tsa arbitrarily hauv qab qhov ntsuas cov zis tam sim no thiab nws tuaj yeem ua haujlwm ib txwm.
3. Lub zog ruaj khov thiab ruaj khov tam sim no ntawm DC tswj fais fab mov tuaj yeem hloov pauv thiab muaj cov xwm txheej zoo sib xws.
4. Cov zis voltage thiab tam sim no qhov tseem ceeb yuav tsum tau muab tso tawm kom raug thiab txheeb xyuas.
5. Rau DC tswj cov khoom siv hluav taws xob nrog cov zis hluav taws xob thiab cov txiaj ntsig tam sim no, ntau tig potentiometers thiab voltage thiab tam sim no trimmer potentiometers lossis ncaj qha digital inputs feem ntau yog siv.
6. Yuav tsum muaj kev tiv thaiv zoo tshaj plaws. Thaum lub sijhawm luv luv lossis kev ua haujlwm tsis zoo tshwm sim ntawm qhov kawg tso tawm, DC lub zog ruaj khov yuav tsum tsis txhob raug puas tsuaj. Tom qab tshem tawm cov kev ua haujlwm txawv txav, nws tuaj yeem ua haujlwm tau sai sai.
DC stabilized fais fab mov siv txheej txheem
1) Qhib lub hwj huam mov. Tsuas yog txuas cov khoom siv hluav taws xob tswj tau rau hauv Circuit Court.
(2) Qhib lub hwj huam mov. Nyob rau hauv cov ntaub ntawv ntawm tsis muaj-load kev twb kev txuas, nias lub ntsiab fais fab hloov, thiab tom qab ntawd tig rau DC tso zis hloov ntawm lub hwj huam mov kom lub hwj huam mov ua hauj lwm ib txwm (qee yam yooj yim adjustable fais fab mov tsuas muaj ib tug loj hwj chim hloov thiab tsis muaj kev ywj pheej. DC tso zis hloov). Lub sijhawm no, qhov kev khiav hauj lwm tam sim no thiab cov zis tam sim no tau tshwm sim ntawm lub zog digital ntsuas.
(3) Los ntawm kev kho qhov hluav taws xob teeb tsa pob qhov rooj, cov voltmeter digital tuaj yeem tso saib lub hom phiaj voltage thiab ua kom tiav qhov teeb tsa voltage. Rau cov khoom siv hluav taws xob nrog kev hloov kho tam sim no txwv, muaj ob txheej txheej txheem tswj hwm qhov hluav taws xob thiab tam sim no. Thaum kho, qhov sib txawv yuav tsum tau ua kom meej meej. Thiab xyuam xim rau lo lus "VOLTAGE" ntawm qhov voltage potentiometer. Lub potentiometer rau kev hloov kho tam sim no feem ntau muaj lo lus "CURRENT".
(4) Kev teeb tsa tam sim no: Nias thiab tuav "Limit" ntawm lub hwj chim sawb ib ntus. Lub ammeter yuav tso saib tus nqi tam sim no. Tswj qhov tam sim no los ntawm kev kho cov pob qhov rooj tam sim no. Feem ntau
Nias thiab tuav lub pob "Limit" ntawm lub hwj chim vaj huam sib luag. Lub sijhawm no, ammeter yuav tso saib tus nqi tam sim no. Kho cov pob qhov rooj tam sim no kom tus nqi tam sim no mus txog qib uas tau teev tseg. Feem ntau, qhov kev txwv tam sim no tuaj yeem teeb tsa ntawm 120 lub zog hluav taws xob nrog qhov siab tshaj plaws tam sim no. Tsis muaj qhov tshwj xeeb hloov qhov tseem ceeb rau kev txwv tam sim no. Tus neeg siv yuav tsum tau luv-circuit qhov tso zis raws li cov lus qhia, thiab tom qab ntawd teeb tsa theem txwv tam sim no raws li qhov luv-circuit tam sim no thiab lub pob qhov txwv tam sim no. Qhov yooj yim adjustable voltage-stabilized fais fab mov tsis muaj ib tug tam sim no qhov chaw ua hauj lwm los yog ib tug sib xws knob.
(5) Overvoltage tiv thaiv OVP teeb tsa. Overvoltage teeb yog hais txog kev txwv ntxiv rau qhov txwv tsis pub dhau voltage nyob rau hauv qhov hloov kho qhov hluav taws xob ntau ntawm lub zog hluav taws xob nws tus kheej kom tiv thaiv lub zog hluav taws xob los ntawm kev tawm hluav taws xob ntau dhau thaum ua haujlwm tsis raug.
Kev teeb tsa overvoltage hais txog kev txwv qhov txwv siab tshaj nyob rau hauv qhov hloov kho qhov hluav taws xob ntau ntawm lub zog hluav taws xob nws tus kheej kom tiv thaiv lub zog hluav taws xob los ntawm kev tawm hluav taws xob ntau dhau thaum ua haujlwm tsis raug. Thaum teeb tsa OVP qhov hluav taws xob, ua ntej kho qhov hluav taws xob kev khiav hauj lwm voltage mus rau lub hom phiaj overvoltage point, thiab tom qab ntawd maj mam kho lub OVP potentiometer kom lub hwj chim tiv thaiv tsuas yog ua. Lub sijhawm no, OVP tau txiav txim siab. Tom qab ntawd, tua lub hwj chim, txo qhov kev khiav hauj lwm voltage, thiab koj tuaj yeem ua haujlwm ib txwm.
(6) Kev sib txuas lus interface parameter teeb tsa thiab chaw taws teeb tswj kev ua haujlwm. Rau kev tswj hwm hauv cheeb tsam (kev ua haujlwm vaj huam sib luag), cov chaw taws teeb tswj yuav tsum raug muab tua. Kev sib txuas lus interface yuav tsum tau teeb tsa raws li kev sib txuas lus, tab sis tsis yog daim ntawv thov hauv zos.
