Lub reactor tam sim no txwv tsis pub yog lub kauj uas muaj qhov ruaj khov inductive tsis kam. Cov cuab yeej txuas nrog hauv series hauv Circuit Court. Raws li txoj cai, cov khoom siv no tsis muaj ferrimagnetic cores. Ib qho hluav taws xob poob ntawm li 3-4% yog suav tias yog tus qauv. Yog hais tias ib tug luv luv Circuit Court tshwm sim, lub ntsiab voltage yog siv rau tam sim no-limiting reactor. Tus nqi siab tshaj plaws yog xam los ntawm tus qauv:

In=(2, 54 Ih/Xp) x100%, qhov twg Ih yog tus ntsuas kab tam sim no thiab Xp yog qhov reactance.

Cov cuab yeej hluav taws xob yog qhov tsim qauv tsim rau kev ua haujlwm ntev hauv cov tes hauj lwm nrog qhov hluav taws xob txog li 35 kV. Lub winding yog ua los ntawm cov xaim hloov tau yooj yim uas ua rau cov dynamic thiab thermal loads los ntawm ntau qhov sib npaug. Lawv tso cai rau koj faib cov dej ntws sib npaug, thaum tshem tawm cov khoom siv dag zog ntawm lub hauv paus ruaj khov.

Txoj kev hloov ntawm cov theem coils raug xaiv kom tau txais qhov sib txawv ntawm cov chaw sib nqus. Qhov no kuj tseem ua rau lub zog tsis muaj zog ntawm kev poob siab luv-circuit tam sim no. Qhib qhov chaw ntawm windings nyob rau hauv qhov chaw contributes raumuab tej yam kev mob zoo heev rau ntuj atmospheric txias. Yog hais tias cov thermal cuam tshuam ntau tshaj qhov tso cai tsis tau, los yog luv luv Circuit Court tshwm sim, yuam airflow yog siv cov kiv cua.

Dry Current Limiting Reactors

Cov khoom siv no yog qhov tshwm sim ntawm kev txhim kho cov ntaub ntawv insulating tshiab raws li cov qauv tsim ntawm silicon thiab organics. Cov chav ua haujlwm tau ua tiav ntawm cov khoom siv mus txog 220 kV. Lub winding ntawm lub kauj yog raug mob nrog ib tug multi-core cable nrog ib tug rectangular cross seem. Nws muaj zog ntxiv thiab yog them nrog txheej tshwj xeeb ntawm organosilicon xim txheej. Ib qho ntxiv ua haujlwm ntxiv yog qhov muaj cov khoom siv hluav taws xob uas muaj cov silicon.

Piv rau cov khoom sib xyaw ua ke, qhuav hom tam sim no-txheej reactor muaj ntau qhov zoo, xws li:

• Lub yuag thiab tag nrho qhov ntev.
• Txhim kho lub zog.
• Kev ntsuas kub nce ntxiv.
• Ntau cov peev txheej ua haujlwm.

Cov khoom siv hluav taws xob no yog nruab nrog cov neeg siv hluav taws xob nrog cov ntawv insulating cable. Nws yog ntsia rau ntawm lub tog raj kheej tshwj xeeb uas nyob rau hauv lub tank nrog roj los yog ib tug zoo xws li dielectric. Lub caij kawg kuj tseem ua lub luag haujlwm ntawm lub tshav kub dissipation.

Kom normalize cov cua sov ntawm rooj plaub hlau, tus tsim muaj xws li sib nqus shunts los yog cov ntxaij vab tshaus ntawmelectromagnets. Lawv tso cai rau koj kom sib npaug ntawm lub zog zaus teb dhau los ntawm kev tig ntawm winding.

Sib nqus hom shunts yog ua los ntawm cov ntawv hlau muab tso rau hauv nruab nrab ntawm cov roj tank, sab xis ntawm phab ntsa. Raws li qhov tshwm sim, ib qho hluav taws xob sib nqus sab hauv yog tsim, uas kaw cov flux tsim los ntawm winding.

Electromagnetic hom cov ntxaij vab tshaus yog tsim los ntawm luv luv-circuited coils ntawm txhuas lossis tooj liab. Lawv raug ntsia ze ntawm phab ntsa ntawm lub thawv. Lawv induce ib qho kev tshwm sim electromagnetic teb, uas txo qhov cuam tshuam ntawm lub ntsiab ntws.

qauv nrog armor

Cov khoom siv hluav taws xob no yog tsim los nrog lub hauv paus. Xws li cov qauv tsim yuav tsum muaj kev suav tseeb ntawm txhua qhov tsis sib xws, uas cuam tshuam nrog qhov muaj peev xwm ntawm saturation ntawm cov hlau nplaum. Kev tshuaj xyuas kom zoo ntawm kev ua haujlwm tseem yuav tsum tau ua.

Armored cores ua los ntawm cov hlau hluav taws xob ua kom nws tuaj yeem txo qhov ntev thiab qhov hnyav ntawm lub reactor nrog rau kev txo nqi ntawm cov cuab yeej. Nws yog ib qho tsim nyog sau cia tias thaum siv cov khoom siv zoo li no, ib qho tseem ceeb yuav tsum tau coj mus rau hauv tus account: qhov kev poob siab tam sim no yuav tsum tsis pub tshaj tus nqi siab tshaj plaws rau cov cuab yeej no.

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov reactors tam sim no txwv

Tus tsim yog raws li lub kauj winding nrog inductive tsis kam. Nws suav nrog hauv kev tawg ntawm cov khoom siv loj. Cov yam ntxwv ntawm cov khoom no raug xaiv raws li kev ua haujlwm raws li tus qauvqhov voltage tsis poob siab tshaj 4% ntawm tag nrho.

Yog tias muaj xwm txheej kub ntxhov tshwm sim hauv kev tiv thaiv hluav taws xob, tam sim no-txheej reactor, vim yog qhov inductance, tua qhov tseem ceeb ntawm qhov ua haujlwm siab-voltage, thaum tib lub sijhawm muaj cov surge tam sim no.

Cov tswv yim ntawm kev ua haujlwm ntawm cov cuab yeej ua pov thawj qhov tseeb tias nrog kev nce hauv inductance ntawm lub kauj, qhov txo qis ntawm qhov cuam tshuam ntawm kev poob siab tam sim no tau pom.

Ntse

Cov cuab yeej hluav taws xob nyob rau hauv kev txiav txim siab yog nruab nrog windings uas muaj cov hlau nplaum ua los ntawm cov hlau phaj, uas ua rau kom muaj zog reactive. Nyob rau hauv xws li units, nyob rau hauv cov ntaub ntawv ntawm qhov kev tso cai ntawm loj tam sim no los ntawm lub lem, saturation ntawm cov khoom tseem ceeb yog pom, thiab qhov no ua rau ib tug txo nyob rau hauv nws tam sim no-limiting tsis. Yog li ntawd, cov khoom siv no tsis siv dav.

Feem ntau tam sim no txwv cov reactors tsis tau nruab nrog steel cores. Qhov no yog vim qhov tseeb tias qhov ua tiav ntawm qhov xav tau inductance yam ntxwv yog nrog los ntawm kev nce ntxiv hauv qhov loj thiab qhov ntev ntawm lub fixture.

Surge short-circuit tam sim no: nws yog dab tsi?

Vim li cas peb thiaj xav tau lub tshuab hluav taws xob tam sim no ntawm 10 kV lossis ntau dua? Qhov tseeb yog tias nyob rau hauv hom nominal, cov khoom siv hluav taws xob high-voltage siv rau kev kov yeej qhov siab tshaj plaws ntawm cov hluav taws xob hluav taws xob. Nws, nyob rau hauv lem, muaj ib tug active thiab reactive load, uas muaj capacitive thiab inductive couplings. Yog li ntawd, ib qho kev khiav hauj lwm tam sim no yog generated, uas yog optimized siv impedanceCircuit Court, hwj chim thiab voltage qhia.

Thaum lub sijhawm luv luv tshwm sim, lub hauv paus yog shunted los ntawm randomly txuas lub siab tshaj plaws load nyob rau hauv ua ke nrog nrog rau yam tsawg kawg nkaus active resistance, uas yog ib txwm rau cov hlau. Nyob rau hauv cov ntaub ntawv no, tsis muaj lub reactive tivthaiv ntawm lub theem yog pom. Lub luv luv Circuit Court theem qhov sib npaug hauv kev ua haujlwm Circuit Court, tsim cov hom tshiab tam sim no. Kev hloov pauv ntawm ib hom mus rau lwm qhov tsis tshwm sim tam sim ntawd, tab sis nyob rau hauv hom ncua sij hawm.

Lub sijhawm hloov pauv tam sim no, qhov sinusoidal thiab tag nrho cov txiaj ntsig hloov. Tom qab luv luv, cov ntaub ntawv tshiab tam sim no tuaj yeem tau txais ib daim ntawv yuam sij los yog pub dawb aperiodic complex form.

thawj qhov kev xaiv ua rau rov ua dua qhov kev teeb tsa ntawm cov khoom siv hluav taws xob, thiab tus qauv thib ob cuam tshuam nrog kev hloov pauv ntawm qhov ntsuas hauv jumps nrog maj mam txo. Nws yog tsim los ntawm ib tug capacitive load ntawm tus nqi nominal, xam raws li ib tug tsis ua hauj lwm rau ib tug tom ntej luv luv Circuit Court.
