Nyob rau hauv txhua lub tsheb niaj hnub muaj ib tug tsim hluav taws xob network, qhov voltage nyob rau hauv uas yog stabilized los ntawm ib tug tshwj xeeb chav tsev - ib tug relay-regulator.Nyeem tag nrho txog cov relay-regulators, lawv hom uas twb muaj lawm, tsim thiab kev ua haujlwm, nrog rau kev xaiv thiab hloov ntawm cov khoom no hauv kab lus.
Dab tsi yog qhov voltage regulator relay?
Voltage regulator relay (voltage regulator) yog ib feem ntawm lub tsheb hluav taws xob;Ib qho khoom siv hluav taws xob, hluav taws xob hluav taws xob lossis hluav taws xob uas muab kev txhawb nqa rau qhov kev ua haujlwm ntawm qhov hluav taws xob hauv hluav taws xob hauv hluav taws xob hauv qee qhov kev txwv.
Lub tshuab hluav taws xob ntawm lub tsheb tau tsim nyob rau hauv ib txoj kev uas thaum lub hwj chim unit nres, lub roj teeb (roj teeb) ua raws li lub hwj chim qhov chaw, thiab thaum nws pib, lub generator hloov ib feem ntawm lub cav fais fab mus rau hauv hluav taws xob.Txawm li cas los xij, lub tshuab hluav taws xob muaj qhov teeb meem tseem ceeb - qhov hluav taws xob ntawm qhov tam sim no tsim los ntawm nws nyob ntawm qhov ceev ntawm lub crankshaft, nrog rau cov khoom siv tam sim no los ntawm kev thauj khoom thiab qhov kub thiab txias.Txhawm rau tshem tawm qhov teeb meem no, siv cov cuab yeej pab cuam - relay-regulator lossis tsuas yog tus tswj hluav taws xob.
Lub voltage regulator daws ntau yam teeb meem:
● Voltage stabilization - tswj qhov voltage ntawm on-board network nyob rau hauv cov kev txwv (nyob rau hauv 12-14 los yog 24-28 volts nrog permissible deviations);
● Kev tiv thaiv lub roj teeb los ntawm kev tso tawm los ntawm lub tshuab hluav taws xob circuits thaum lub cav nres;
● Qee hom kev tswj hwm - tsis siv neeg kaw ntawm lub oob khab thaum lub cav pib ua tiav;
● Qee hom kev tswj hwm - kev sib txuas tsis siv neeg thiab kev sib txuas ntawm lub tshuab hluav taws xob los ntawm lub roj teeb kom them nws;
● Qee hom kev tswj hwm - hloov qhov voltage ntawm on-board network nyob ntawm qhov kev nyab xeeb tam sim no (hloov ntawm lub tshuab hluav taws xob mus rau lub caij ntuj sov thiab lub caij ntuj no).
Tag nrho cov tsheb, tsheb laij teb thiab ntau lub tshuab yog nruab nrog relay-regulators.Kev ua haujlwm tsis zoo ntawm chav tsev no cuam tshuam kev ua haujlwm ntawm tag nrho cov hluav taws xob, qee qhov no tuaj yeem ua rau tawg ntawm cov khoom siv hluav taws xob thiab hluav taws xob.Yog li ntawd, lub faulty regulator yuav tsum tau hloov sai li sai tau, thiab rau qhov tseeb xaiv ntawm ib feem tshiab, nws yog tsim nyog los nkag siab txog cov uas twb muaj lawm hom, tsim thiab lub hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm regulators.
Hom, tsim thiab lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm relay-regulator
Niaj hnub no, muaj ntau ntau hom relay-regulators, tab sis lawv cov hauj lwm yog raws li tib lub hauv paus ntsiab lus.Ib qho regulator muaj peb yam sib cuam tshuam:
- Ntsuas (rhiab heev) yam;
- Sib piv (tswj) lub caij;
- Cov cai tswjfwm.
Lub regulator txuas nrog lub teb winding ntawm lub tshuab hluav taws xob (OVG), ntsuas thiab hloov lub zog tam sim no hauv nws - qhov no ua kom muaj kev ruaj ntseg voltage.Feem ntau, qhov system no ua haujlwm raws li hauv qab no.Lub ntsuas ntsuas, tsim los ntawm lub hauv paus ntawm qhov sib faib hluav taws xob, lossi saib xyuas lub zog tam sim no hauv OVG thiab hloov nws mus rau hauv lub teeb liab los mus rau qhov sib piv (tswj) lub caij.Ntawm no, lub teeb liab yog piv nrog tus qauv - tus nqi hluav taws xob uas ib txwm yuav tsum ua haujlwm hauv lub tsheb hluav taws xob.Cov khoom siv tuaj yeem tsim los ntawm kev co relays thiab zener diodes.Yog hais tias lub teeb liab los ntawm lub ntsuas ntsuas sib haum mus rau qhov siv (nrog rau kev tso cai sib txawv), ces tus tswj hwm tsis ua haujlwm.Yog hais tias cov khoom xa tuaj txawv ntawm cov teeb liab siv nyob rau hauv ib qho kev taw qhia lossis lwm qhov, ces qhov sib piv cov khoom tsim cov teeb liab tswj los mus rau cov txheej txheem tswj tau tsim los ntawm relays, transistors lossis lwm yam khoom.Cov txheej txheem tswj kev hloov pauv tam sim no hauv OVG, uas ua tiav qhov rov qab los ntawm qhov hluav taws xob ntawm qhov tso zis ntawm lub tshuab hluav taws xob mus rau qhov kev txwv.
Voltage regulator block daim duab
Raws li twb tau hais lawm, cov regulator units yog tsim los ntawm ib tug sib txawv lub hauv paus, nyob rau hauv lub hauv paus no cov cuab yeej muab faib ua ob peb hom:
● Vibrating;
● Tiv tauj-transistor;
● Hluav taws xob transistor (sib cuag);
● Integral (transistor, ua los ntawm kev siv tshuab ua ke).
Daim duab ntawm kev vibration relay-regulator
Keeb kwm, cov khoom siv vibration yog thawj zaug tshwm sim, uas, qhov tseeb, hu ua relay-regulators.Nyob rau hauv xws li ib tug ntaus ntawv, tag nrho peb chav nyob yuav ua ke nyob rau hauv ib tug tsim - ib tug electromagnetic relay nrog ib txwm kaw kev sib cuag, txawm hais tias lub ntsuas yuav ua tau nyob rau hauv daim ntawv ntawm ib tug divider ntawm resistors.Lub zog quab yuam ntawm lub caij nplooj ntoos hlav rov qab ua raws li tus nqi siv nyob rau hauv lub relay.Feem ntau, lub relay-regulator ua haujlwm yooj yim.Nrog rau qhov tsis tshua muaj tam sim no ntawm OVG lossis qhov hluav taws xob qis ntawm qhov tso zis ntawm lub tshuab hluav taws xob (nyob ntawm txoj kev sib txuas ntawm tus tswj hwm), lub relay tsis ua haujlwm thiab tam sim no ntws ywj pheej los ntawm nws cov neeg kaw - qhov no ua rau muaj qhov nce ntawm qhov hluav taws xob.Thaum qhov hluav taws xob nce siab, lub relay tau tshwm sim, qhov hluav taws xob hauv Circuit Court poob thiab lub relay raug tso tawm, qhov hluav taws xob nce ntxiv thiab relay rov tshwm sim dua - qhov no yog li cas tus relay hloov mus rau hom oscillation.Thaum qhov hluav taws xob ntawm lub tshuab hluav taws xob hloov pauv hauv ib qho kev taw qhia lossis lwm qhov, qhov zaus oscillation ntawm relay hloov, uas ua kom muaj kev ruaj ntseg voltage.
Tam sim no, kev co relays, uas muaj kev ua haujlwm tsawg thiab tsis txaus ntseeg, tsis siv rau hauv tsheb.Nyob rau hauv ib lub sij hawm, lawv tau hloov los ntawm kev sib cuag-transistor regulators, nyob rau hauv uas ib tug co relay yog siv raws li ib tug sib piv / tswj lub ntsiab, thiab ib tug transistor ua hauj lwm nyob rau hauv lub ntsiab hom yog siv raws li ib tug regulating lub ntsiab.Ntawm no, lub transistor plays lub luag hauj lwm ntawm relay hu, yog li ntawd, nyob rau hauv dav dav, lub lag luam ntawm xws li ib tug regulator yog zoo ib yam li cov uas tau piav saum toj no.Niaj hnub no, regulators ntawm hom no yog xyaum hloov los ntawm contactless transistors ntawm ntau yam tsim.
Nyob rau hauv contactless transistor regulators, lub relay yog hloov los ntawm ib tug yooj yim semiconductor ntaus ntawv - ib tug zener diode.Lub zener diode stabilization voltage yog siv raws li tus nqi siv, thiab cov khoom tswj tau tsim los ntawm cov transistors.Ntawm qhov tsis tshua muaj hluav taws xob, zener diode thiab transistors nyob rau hauv xws li lub xeev uas qhov siab tshaj plaws tam sim no tau muab rau OVG, uas ua rau muaj qhov nce ntawm qhov hluav taws xob.Thaum cov theem voltage yuav tsum tau mus txog, lub zener diode thiab transistors hloov mus rau lwm lub xeev thiab pib ua hauj lwm nyob rau hauv oscillatory hom, uas, raws li nyob rau hauv cov ntaub ntawv ntawm ib tug pa relay, muab voltage stabilization.
Niaj hnub nimno hluav taws xob regulators yog tsim los ntawm transistors thiab muaj peev xwm muaj ib tug mem tes-dav modulator (PWM), los ntawm qhov kev hloov zaus ntawm Circuit Court yog teem thiab lub cuab yeej tuaj yeem nkag mus rau hauv kev tswj hwm tsheb.
Cov tsis sib cuag transistor regulators tuaj yeem ua tau ntawm cov khoom sib cais thiab kev siv thev naus laus zis.Hauv thawj kis, cov khoom siv hluav taws xob zoo ib yam (zener diodes, transistors, resistors, thiab lwm yam) yog siv, hauv qhov thib ob, tag nrho cov chav tsev yog sib sau ua ke ntawm ib nti los yog compact thaiv ntawm cov xov tooj cua compact uas muaj cov khoom sib xyaw.
Cov kev xav tau tsim muaj qhov yooj yim tshaj plaws relay-regulators, hauv kev muaj tiag, ntau cov cuab yeej siv nrog ntau lub koom haum pab tau siv - pib tswj, tiv thaiv cov roj teeb tawm los ntawm lub tshav pob winding, kho cov kev khiav hauj lwm hom nyob ntawm qhov kub thiab txias, tiv thaiv Circuit Court, kuaj tus kheej thiab lwm yam. .Nyob rau ntau lub relay-regulators ntawm tsheb laij teb thiab tsheb thauj khoom, muaj peev xwm ntawm phau ntawv hloov kho ntawm stabilization voltage kuj yog siv.Qhov kev hloov kho no yog ua los ntawm kev siv lub zog hloov pauv (hauv cov khoom siv vibration - siv lub caij nplooj ntoos hlav) los ntawm kev siv lub zog los yog kov tso rau sab nraum lub tsev.
Regulators yog tsim nyob rau hauv daim ntawv ntawm me me blocks mounted ncaj qha rau ntawm lub tshuab hluav taws xob los yog nyob rau hauv ib tug yooj yim qhov chaw ntawm lub tsheb.Cov cuab yeej tuaj yeem txuas nrog OVG thiab / lossis cov khoom tso tawm ntawm lub tshuab hluav taws xob, lossis mus rau ntu ntawm cov khoom siv hluav taws xob on-board qhov twg yuav tsum muaj qhov ntsuas hluav taws xob ruaj khov.Hauv qhov no, ib lub davhlau ya nyob twg ntawm OVG yuav tsum txuas nrog "+" lossis "-" on-board fais fab mov.
