Nyob rau lub caij ntuj sov chaw nyob lossis hauv cov tsev nyob hauv lub tebchaws, muaj teeb meem txog kev xaim hluav taws xob hauv lub network feem ntau tshwm sim. Hauv qhov no, muaj tsuas yog ib qho kev daws teeb meem - ib qho voltage stabilizer rau lub tsev.
Kev faib tawm kom ruaj khov. Qhov voltage tswj qhov twg zoo dua?
Siab lossis qis hluav taws xob tuaj yeem ua rau tsis tiav ntawm cov cuab yeej hluav taws xob feem ntau. Lub zog hluav taws xob tshwm sim vim qhov nruab nrab ntawm thaj chaw hauv cheeb tsam ntawm qhov nruab nrab qhov hluav taws xob dhau tag nrho ntev ntawm cov kab hluav taws xob.
Qhov ntsuas hluav taws xob 220V tuaj yeem nyob ntawm qhov nruab nrab ntawm kab. Nyob ntawm qhov kev ncua deb ntawm qhov point no lub tsev lossis tsev me nyob, qee qhov hluav taws xob hloov tau. Raws li, cov tsev nyob ze rau qhov chaw txuas feem ntau feem ntau yuav tsum muaj qhov nce hluav taws xob hauv lub network. Cov tsev uas nyob deb ntawm qhov chaw txuas yog cuam tshuam los ntawm hluav taws xob hluav taws xob.
Txhawm rau tiv thaiv lub tsev thiab khoom siv hluav taws xob los ntawm kev siv hluav taws xob, muaj cov cuab yeej tshwj xeeb - cov ntsuas hluav taws xob rau cov tsev me.
Lub ntsiab lus ntawm tus stabilizer yog tswj cov input voltage. Nws hloov qhov hloov ntawm qhov hloov pauv, sib npaug tam sim no thiab muab cov khoom siv hluav taws xob kom raug rau qhov tsim tawm.
Qhov feem ntau hom hom stabilizers:
- Servo-uas tau tsav;
- Daim Ntawv Cauj;
- Hluav taws xob lossis thyristor.
Servo voltage tswj kev tswj hwm
Cov stabilizers hloov tus lej qee qhov ntawm tig ntawm qhov hloov pauv, thiaj li tswj tau qhov tso tawm hluav taws xob. Lub servo-tsav mus txav mus los, txav mus raws qhov hloov ntawm lub hloov pauv, tswj ntsuas qhov nkag voltage voltage mechanically. Cov cuab yeej siv ntawm hom no tsis ntseeg tau.
- Qhov zoo: tus nqi qis;
- Disadvantages: ntau ntawm cov tshuab tsis sib xws uas feem ntau swb;
- Feem ntau qhov tsis ua haujlwm: kev hloov pauv ntawm kev ua haujlwm ntawm servo-tsav mechanism, ua raws lub kaum-graphite sib dhos.
Relay voltage tswj kev lag luam
Nws muaj lub tshuab hluav taws xob hloov uas hloov mus rau lub ntsuas hluav taws xob thiab muaj qhov thaiv ntawm ntau lub zog xa hluav taws xob.
- Qhov zoo: nws nyob nruab nrab tus nqi nruab nrab nyob rau hauv kev ua lag luam ntawm stabilizers thiab muaj tsawg dua cov khoom siv tshuab;
- Qhov tsis zoo: qhov kev pab cuam tsawg lub neej (los ntawm 1.5 txog 2 xyoos, nyob ntawm qhov zaus ntawm lub hwj chim nce hauv lub network);
- Pom tshwm sim ib txwm: cov nplais sib chwv.
Hluav taws xob (thyristor) voltage stabilizers
Lub tshuab tseem ceeb ntawm cov tshuab hluav taws xob hauv tshuab hluav taws xob yog hluav taws xob hluav taws xob, heistors, thyristor hloov, capacitors. Cov no yog cov hom kev txhim khu kev qha tshaj plaws. Lawv muaj lub sijhawm ua haujlwm ntev thiab yuav yog qhov kev xaiv zoo tshaj plaws thaum xaiv qhov voltage stabilizer rau lub tsev.
- Cov txiaj ntsig zoo: nrawm (cov lus teb ntawm input voltage txog 20 ms.), Lub lag luam uas ntsiag to (ib qho tseem ceeb hauv chav nyob), lub sijhawm tsis ua haujlwm ntawm lub sijhawm ntev, yuav tsum tsis muaj txij nkawm, yooj yim interface.
- Qhov tsis zoo: tus nqi (kwv yees li ob zaug kim dua ntawm relay stabilizer, thiab tseem yuav luag peb zaug kim dua rau servo tsav).
Qhov voltage tswj qhov twg zoo dua?
Qhov zoo tshaj plaws rau kev muab lossis tom tsev yuav yog qhov tsim hluav taws xob. Nws tuaj yeem txuas tau tam sim ntawd tom qab ntsuas 'meter' kom paub meej txog kev nyab xeeb ntawm cov khoom siv hluav taws xob thoob plaws lub tsev.
Yuav ua li cas xaiv lub ntsuas hluav taws xob rau lub tsev
Txhawm rau xaiv cov qauv tsim hluav taws xob tsis zoo rau lub tsev lossis chaw nyob thaum lub caij ntuj sov, nws yog qhov tsim nyog los txiav txim siab tus naj npawb ntawm cov theem ntawm cov xaim hluav taws xob qhov ntsuas.
Nrog rau peb-theem hluav taws xob voltage, feem, yuav tsum muaj peb-theem stabilizer. Qee tus tswv tsim kho peb-ib-theem theem stabilizers thiab txuas lawv ua ke.
Yuav luag txhua lub teb chaws cov khoom nkag muaj ib theem. Rau cov kev sib txuas zoo li no, yuav tsum muaj ib theem-stabilizer. Hluav taws xob (thyristor lossis xya-theem) lub tshuab hluav taws xob yog qhov zoo tshaj plaws thiab txhim khu kev qha ntawm cov hluav taws xob ib-theem hluav taws xob corrector.
Ib qho ntawm qhov ntsuas tseem ceeb thaum xaiv lub stabilizer yog nws lub zog, txij li qee tus qauv muaj cov cuab yeej tsis zoo ntawm lub hwj chim thaum lub voltage poob hauv lub network.
Cov lag luam zoo-paub ntawm thyristor stabilizers Lider PS (NPP Cov Chaw Sib Koom Tes), thiab raws li Volter SMPTO xya-voltage hluav taws xob cov khoom siv hluav taws xob (ChNPP Electromir Tuam Txhab) muaj cov khoom lag luam ntau.
Kev ntsuas kom nrawm muaj cov yam ntxwv zoo ntawm lub zog thiab kev ua haujlwm. Tag nrho cov qauv ntawm cov tuam txhab muaj huab cua zoo ua tau zoo (huab cua tsis kam thiab noo noo tsis kam nyob rau hauv thaj tsam ntawm -40 С + 40 С), nrog rau cov impregnation tshwj xeeb muaj pes tsawg leeg ntawm txhua cov nodes thiab sab hauv. Xws li cov khoom tsis suav nrog qhov tshwm sim ntawm luv luv Circuit Court thaum hws tshwm hauv sab hauv lub stabilizer.
Yog hais tias lub stabilizer tsis muaj qhov chaw noo noo-tiv taus kev kho mob, nws tsis pom zoo kom ua haujlwm nws ntawm sub-zero kub.
Lider PS Stabilizers
Tsim los tswj lub tshuab hluav taws xob kom ceev, thaum muaj kev hloov pauv hauv AC network, lub zog thiab kev tiv thaiv ntawm ntau yam khoom siv hluav taws xob hauv tsev. Lub zog hluav taws xob muaj ntau yam ntawm 100 VA txog 30 txhiab VA. (Ib leeg-theem network) thiab 2.7 - 90 kVA (peb-theem network). Tsim rau round-lub-moos ua haujlwm tiv thaiv lub tsev network los ntawm voltage surges nyob rau hauv thaj tsam 125-275V (qauv W-30), 110-320V (qauv W-50).
Qhov yooj yim tshaj plaws yog qhov Lider PS stabilizers ntawm W series. Lawv cov hluav taws xob txhawm rau kom paub tseeb kev ruaj khov (qhov yuam kev yuav tsis ntau tshaj 4.5%), thiab cov lus teb ceev ntawm cov cim tswj yog 250 V / sec. Tus stabilizer yog tswj los ntawm lub tshuab hluav taws xob microprocessor (maub los).
Volter stabilizers SMPTO
Tsim los kho qhov ntsuas qhov voltage nyob hauv cov network sab hauv, qhov twg qhov sib txawv ntawm qhov hloov npe me yog li 5%. Cov chaw tsim khoom muaj cov kev xaiv ntau ntawm cov khoom uas muaj cov khoom sib txawv ntawm qhov sib txawv ntawm 0.7 - 10%, nrog rau kev kho cov kab hluav taws xob qis tshaj plaws ntawm 85V. Lub cev ruaj khov thiab lub tshuab khov kho yog tswj hwm los ntawm cov ntse, cov kev ua haujlwm ntawm kev tswj hwm uas yog tsim los ntawm kev siv khoom nruab nrab.
Raws li kev soj ntsuam ntawm voltage stabilizers rau tsev, Volter SMPTO thiab Lider PS yog qhov kev xaiv zoo tshaj plaws. Lawv yog cov neeg nyob ntsiag to, kev sib cog lus thiab ntseeg tau hauv kev daws teeb meem nrog kev siv hluav taws xob hauv teb chaws lossis tsev network.
