Ama-reactor alawulwa nguzibuthe

Yini i-MCR?

Ama-reactor alawulwa nguzibuthe (MCR) wuhlobo lwe-shunt reactor enamandla alungisekayo, esetshenziselwa kakhulu isinxephezelo samandla asebenzayo wesistimu yamandla.

I-MCR ine-valve kazibuthe yokulawula ukungeneka kwe-reactor core, esuthisa wonke umongo wensimbi futhi ithuthukise ukusebenza kakhulu ngokushintsha ukwakheka kwesithando somlilo kazibuthe ngesisekelo sokugcwala kwamandla kazibuthe okuvamile kanye ne-reactor. ukuze bushelelezi ukufakwa okusebenzayo kwesilawuli esingenawo ama-electrodeless. Umdwebo wohlelo umi kanje:

Isebenza kanjani i-MCR

I-MCR isuselwe kumgomo wokusebenza uzibuthe we-DC, kusetshenziswa umongo owengeziwe we-DC we-DC excitation magnetization reactor, ngokulungisa idigri yamagnetic saturation yomgogodla we-MCR, ukushintsha ukufinyeleleka kwengqikithi, ukuze kuzuzwe inani eliqhubekayo lokusabela eliguquguqukayo. Isekethe kazibuthe ye-shunt yakhiwe ngomongo endaweni engagcwele futhi ingqikithi endaweni egcwele ihlelwe ngokushintshana kumongo we-reactor; i-excitation magnetization of the core yi-excitation yamanje ye-DC eyengeziwe ilawulwa ngokulungisa i-thyristor triggering conduction angle; i-magnetization degree kanye nesifunda sokugcwaliswa kwengqikithi endaweni engagcwaliswanga kanye nesifunda sokugcwala sishintshwa ngokulungisa indawo noma ukumelana nozibuthe kwengqikithi endaweni engagcwaliswanga kanye nesifunda sokugcwala kumjikelezo kazibuthe we-shunt I-degree magnetic saturation of the umgogodla ungabona ukulungiswa okuqhubekayo nokusheshayo kwevelu yokusabela ukusuka ku-1% ukuya ku-100%. Ihlanganiswe ne-capacitor, inganikeza amandla asebenzayo aguqukayo futhi angalungile, ngakho-ke ingakwazi ukulawula i-voltage yesistimu namandla asebenzayo ngokunembe kakhulu nangokushesha. Ngenxa yokuthi awukho noma umthelela omncane kakhulu kanye ne-inrush ebangelwa ukushintsha kwe-capacitor, ukuthembeka nempilo yesevisi yedivayisi ingathuthukiswa kakhulu. Ingakwazi ukunxephezela izigaba ezintathu ngokuhlukene, ikakhulukazi esimweni sokungalingani kwamandla ezigaba ezintathu.

Uyini umsebenzi we-MCR

1. Khulisa isici samandla futhi unciphise ukulahlekelwa kolayini okubangelwa amandla asebenzayo , thuthukisa ikhwalithi yamandla abasebenzisi.isici samandla singafinyelela izimfuneko zika-0.90-0.99.

2. Ukucindezela nokuhlunga ama-harmonics, ukunciphisa ukuguquguquka kwamandla kagesi, ukucwayiza, ukuhlanekezela kanye nokusimamisa i-voltage, kuthuthukisa impilo yesevisi yama-transformer, izintambo zokudlulisela kanye nezinye izinto zokusebenza zikagesi.

3.Njengesinxephezelo samandla asebenzayo, i-MCR ingalungisa amandla asebenzayo aphumayo ngokushelela, anemisebenzi eminingi kunempahla yesinxephezelo samandla asebenzayo avamile.

4. Nciphisa umthelela wegridi yamandla wendawo njenge-asynchronous motor start, ukusebenza kwesithando somlilo se-arc kagesi futhi uthuthukise ukuphepha kwesistimu, ikakhulukazi kunethiwekhi yamanje ebuthakathaka.

Yiziphi izinzuzo ze-MCR

1.ayikho into yesenzo ngaphakathi, engeke ibe nomthelela ohlelweni;

2.Ukulawulwa okungenazinyathelo kungathola isinxephezelo esiqhubekayo samandla asebenzayo;

3.Ukusebenza okuphephile, ukunakekelwa kwamahhala nokunganakiwe;

4.Ukulahlekelwa okuphansi (ukulahlekelwa ngokwakho

5.Ukulahleka kwamandla asebenzayo okuphansi;

I-6.I-harmonic encane (ngaphansi kuka-50% wemikhiqizo efanayo);

I-7.Ikhwalithi ethembekile, impilo ende yomkhiqizo (iminyaka engaphezu kwe-25);

8.Ukufakwa okulula nendawo encane yaphansi;

9.Umthamo wokulayisha oqinile, ungalayisha ngokweqile u-150% ngesikhathi esifushane;

10.Akukho ukuphazamiseka kukazibuthe kanye nokungcoliswa kwemvelo.

Iyiphi indawo esebenzisa i-MCR

Umzila wesitimela osebenza ngogesi

Umthwalo wesiteshi sikaloliwe esidonsa ugesi uyadlula. Lapho i-locomotive kagesi idlula, umthwalo uvela ngokuzumayo. Ngemva kokudlula kwesitimela, umthwalo uyanyamalala. Ukusebenzisa i-switching capacitor evamile kuzobangela ukuthi isiteshi esidonsayo sishintshe izikhathi ezingamakhulu nsuku zonke. Isenzo, esinciphisa kakhulu impilo yesevisi yemishini kagesi, futhi i-asymmetry yesitimela esifakwe ugesi ibangela ukuthi ingxenye yayo yokulandelana okungalungile ibe yingozi kakhulu.

Amalahle Namakhemikhali

Kunenani elikhulu lemithwalo ephazamisayo eyenzeka ngezikhathi ezithile njengama-hoists ezinkampanini zamalahle, okungagcini nje ngokuba nokuguquguquka okukhulu kwamandla asebenzayo kodwa futhi nokungcoliswa okukhulu kwe-harmonic, okubangela kalula ukulimala kwezinto zikagesi futhi kuthinte impilo yesevisi yezinto zokusebenza zikagesi.

I-Metallurgy

Umthwalo we-rolling Mill kanye nesithando somlilo se-arc kagesi ohlelweni lwe-metallurgical uhlobo lomthwalo okhethekile. Ingashintsha umthwalo kusuka enanini elincane ukuya enanini elikhulu kakhulu ngesikhathi esifushane kakhulu (ngaphansi kuka-1s), futhi imvamisa yoshintsho ishesha kakhulu. Ngenxa yalokho, izisetshenziswa zokubonisa kulawa mabhizinisi zihlala zinyakaza ngesivinini esikhulu.

Ipulazi lomoya

Amadivayisi e-SVC asekelwe ku-MCR asetshenziselwa ukulungisa okuqhubekayo, okungathintwayo, nokuguquguqukayo kwamandla asebenzayo eziteshini zepulazi lomoya, ukuthuthukisa isici samandla wesistimu, ukulungisa ngokushesha ukuphuma kwamandla asebenzayo, kanye nokukhuthaza ukutholwa kwamandla kagesi.

Isiteshi samandla

Izinkinga zokusebenzisa i-capacitor ephansi kanye nokuphathwa kokushintsha okunzima zisabalele. Inani elikhulu lamadivayisi e-VQC afakiwe angabangela kalula izinkinga njengokushintshwa njalo kwamabhange e-capacitor kanye namaswishi avamile okulawula amandla kagesi alayishiwe, okunciphisa ukuphila kwemishini futhi kwandise izingozi zokuphepha.

Abasebenzisi bezimboni ezikhethekile

Amabhizinisi endwangu kanye nabakhiqizi bamashubhu ezithombe banezidingo eziphezulu zekhwalithi yemikhiqizo abayikhiqizayo kanye nekhwalithi ye-voltage yegridi yamandla. Ukwehla kwamandla kagesi kungazelelwe noma ukwehla kwesikhashana kuzodala inani elikhulu lemikhiqizo engcolile emikhiqizweni yabo. Ukusebenzisa amadivayisi esinxephezelo samandla asebenzayo ohlobo lwe-MCR kungathuthukisa ikhwalithi yayo kagesi ngesikhathi esifushane.

Iyini i-MCR uhlobo lwe-SVC

I-MCR yohlobo lwe-SVC iphinde ibe enye yezisetshenziswa zesinxephezelo ezisebenzayo ze-shunt. Ilawula ubukhulu be-DC eyengeziwe ye-excitation yamanje ngokulawula i-engeli conduction ye-thyristor yedivayisi ye-excitation ku-MCR, ishintsha ukungeneka kwengqikithi, ishintsha inani lokusabela kwe-reactor, ishintsha ubukhulu bamanje okukhiphayo okusebenzayo, kanye nezinguquko. ubukhulu bomthamo wesinxephezelo esisebenzayo.
