Yintoni i-MCR?

Iireactor ezilawulwa yimagnethi (MCR) luhlobo lwe-shunt reactor enomthamo ohlengahlengiswayo, esetyenziswa kakhulu kwimbuyekezo yamandla asebenzayo enkqubo yamandla.

I-MCR inevalve yemagnethi yokulawula ukungeneka kondoqo wereactor, othi uzalise umbindi wentsimbi uphela kwaye iphucule ukusebenza kakhulu ngokuguqula ubume besithando somlilo ngokwesiseko sobume bemagnethi kunye nereactor. ukuze kugudiswe i-inductance esebenzayo ye-electrodeless regulator. Umzobo woyilo ngolu hlobo lulandelayo:

Isebenza njani i-MCR

I-MCR isekelwe kumgaqo we-DC magnetization, usebenzisa i-DC eyongezelelweyo ye-DC excitation magnetization reactor reactor, ngokulungelelanisa idigri yamagnetic saturation ye-core ye-MCR, ukuguqula ukufikeleleka kombindi, ukuphumeza ixabiso eliqhubekayo lokusabela okuguquguqukayo. I-shunt magnetic circuit iqulunqwe ngundoqo kwingingqi engabonakaliyo kwaye ingundoqo kummandla ogcweleyo olungiselelwe ngokuhlukileyo kwi-core of the reactor; i-excitation magnetic of the core yi-excitation ye-DC eyongezelelweyo yangoku ilawulwa ngokulungelelanisa i-thyristor ebangela i-angle conduction; idigri yemagnetization kunye nommandla wokugcwalisa we-core kwingingqi engasebenziyo kunye nommandla wokuzalisa utshintshwa ngokuhlengahlengisa indawo okanye ukuchasana kwamagnetic kombindi kwingingqi engasebenziyo kunye nommandla wokuzalisa kwisekethe yemagnethi ye-shunt. undoqo unokuqonda uhlengahlengiso oluqhubekayo nolukhawulezayo lwexabiso lokusabela ukusuka kwi-1% ukuya kwi-100%. Idityaniswe ne-capacitor, inokubonelela ngokufanelekileyo kunye nokungalunganga ngokuqhubekayo amandla asebenzayo aguqukayo, ngoko inokulawula i-voltage yenkqubo kunye namandla asebenzayo ngokuchanekileyo nangokukhawuleza ngakumbi. Ngenxa yokuba akukho okanye impembelelo encinci kakhulu kunye ne-inrush ebangelwa ukutshintshwa kwe-capacitor, ukuthembeka kunye nobomi benkonzo yesixhobo kunokuphuculwa kakhulu. Iyakwazi ukubuyisela izigaba ezithathu ngokwahlukeneyo, ngakumbi kwimeko yokungalingani kwamandla kwisigaba sesithathu.

1. Ukwandisa amandla ombane kunye nokunciphisa ilahleko yomgca obangelwa amandla asebenzayo , phucula umgangatho wamandla abasebenzisi.i-power factor inokufikelela kwiimfuno ze-0.90-0.99.

2. Ukucinezela kunye nokucoca i-harmonics, ukunciphisa ukuguquguquka kwamandla ombane, i-flicker, ukuphazamiseka kunye nokuzinzisa i-voltage, ukuphucula ubomi benkonzo yee-transformers, iintambo zokuhambisa kunye nezinye izixhobo zombane.

3. Njengembuyekezo yamandla asebenzayo, i-MCR inokulungelelanisa imveliso yamandla asebenzayo ngokutyibilikayo, enemisebenzi emininzi kunezixhobo zembuyekezo yamandla asebenzayo ngokubanzi.

4. Ukunciphisa impembelelo yegridi yamandla yendawo efana ne-asynchronous motor start, i-electric arc furnace operation kunye nokuphucula ukhuseleko lwenkqubo, ngakumbi kwinethiwekhi yangoku ebuthathaka.

Loluphi uhlobo lwendawo esebenzisa i-MCR

Umbane kaloliwe

Umthwalo wesikhululo esinombane sokuhamba sikaloliwe uyadlula. Xa i-locomotive yombane idlula, umthwalo uvela ngokukhawuleza. Emva kokuba uloliwe edlulile, umthwalo uyanyamalala. Ukusebenzisa i-capacitor yendabuko yokutshintsha kuya kubangela ukuba i-substation ye-traction itshintshe ngamakhulu amaxesha imihla ngemihla. Isenzo, esinciphisa kakhulu ubomi benkonzo yezixhobo zombane, kunye ne-asymmetry yombane wombane ibangela ukuba icandelo layo lokulandelelana elibi libi kakhulu.

Amalahle kunye neMichiza

Kukho inani elikhulu leempembelelo zethutyana ezinje ngee-hoists kumashishini amalahle, angenako ukuguquguquka okukhulu kwamandla asebenzayo kuphela kodwa kunye nongcoliseko olumandla lwe-harmonic, oludala ngokulula umonakalo kwisixhobo sombane kwaye luchaphazele ubomi benkonzo yezixhobo zombane.

Isinyithi

Umthwalo we-rolling mill kunye nesithando sombane se-arc kwinkqubo ye-metallurgical luhlobo lomthwalo okhethekileyo. Iyakwazi ukutshintsha umthwalo ukusuka kwixabiso elincinci ukuya kwixabiso elikhulu kakhulu ngexesha elifutshane kakhulu (ngaphantsi kwe-1s), kwaye ukuphindaphinda kwenguqu kukhawuleza kakhulu. Ngenxa yoko, izixhobo zokubonisa kula mashishini zihlala zijikeleza ngesantya esiphezulu.

Ifama yomoya

Izixhobo ze-SVC ezisekwe kwi-MCR zisetyenziselwa uhlengahlengiso oluqhubekayo, olungaqhagamshelwanga, kunye nohlengahlengiso oluguquguqukayo lwamandla asebenzayo kwizitishi zefama yomoya, ukuphucula imeko yamandla enkqubo, ukulungisa ngokukhawuleza imveliso yamandla asebenzayo, kunye nokukhuthaza ukubuyiswa kombane.

Isitishi sombane

Iingxaki zokusetyenziswa kwe-capacitor ephantsi kunye nokulawulwa kokutshintsha okunengxaki zixhaphakile. Inani elikhulu lezixhobo ze-VQC ezifakelwe ngokulula zinokubangela iingxaki ezinjengokutshintsha rhoqo kweebhanki ze-capacitor kunye neeswitshi zokulawula amandla ombane rhoqo kumthwalo, okunciphisa ubomi bezixhobo kunye nokwandisa umngcipheko wokhuseleko.

Abasebenzisi bemizi-mveliso abakhethekileyo

Amashishini amalaphu kunye nabavelisi betyhubhu yemifanekiso banemfuno eziphezulu zomgangatho weemveliso abazivelisayo kunye nomgangatho wombane wegridi yamandla.
