Ukusetshenziswa kwemboni yohlobo lwe-MCR yedivayisi yesinxephezelo samandla asebenzayo ashukumisayo

Uhlobo lwe-MCR lwedivayisi yesinxephezelo samandla asebenzayo aguqukayo lungasetshenziswa kabanzi kulezi zinkambu ezilandelayo.

1 Uhlelo lwamandla

1) Isiteshi esincane esivamile. Ngokungeza i-MCR enomthamo othile ngesisekelo sebhange le-capacitor yasekuqaleni, ukulawulwa okuguquguqukayo nokuqhubekayo kwamandla asebenzayo esiteshini esingaphansi kuyafezeka, isenzo esivamile sama-circuit breaker siyagwenywa, izinga lokusebenzisa ama-capacitor liyathuthukiswa kakhulu, futhi isici samandla sithuthukisiwe kakhulu.

2) Isiteshi esincane sehabhu. Ngokufaka idivayisi yesinxephezelo samandla esisebenzayo esakhiwe yisihlungi se-mcr+fc esiteshini sehabhu, noma ukwengeza i-MCR ngesisekelo sesihlungi sangempela se-FC ukuze kwakhe idivayisi yesinxephezelo samandla esisebenzayo, ukuthuthukisa ukuzinza kwegridi yamandla nokwandisa umthamo wokudlulisela umugqa.

3) I-reactor ye-voltage ephansi. Ukushintsha i-low-voltage reactor yesiteshi esincane ku-MCR akunayo nje yonke imisebenzi ye-low-voltage reactor, kodwa futhi inomsebenzi wedivayisi yesinxephezelo samandla asebenzayo.

4) Isinxephezelo samandla asebenzayo ngomugqa. Ngokusebenzisa isilinganiso esifanele somthamo we-capacitor kanye nomthamo we-MCR, isenzo se-vacuum contactor singagwenywa ngokuyisisekelo, ukuthembeka nokuphepha kwemishini kungathuthukiswa, futhi impilo yesevisi yemishini inganwetshwa kakhulu.

I-5) Isinxephezelo samandla asebenzayo we-transformer yokusabalalisa. Ubuchwepheshe be-TSc+mcr bamukelwa ukuze kuthuthukiswe kakhulu ukunemba kwesinxephezelo (0.2 kvar), kunciphise kakhulu imvamisa yesenzo sokushintsha, futhi kuqinisekiswe ngempumelelo ukuthi isinxephezelo samandla esisebenzayo sesiguquli sokusabalalisa sifinyelela kusici samandla aphezulu esingu-0 99-1, qaphela ukusebenza kwangempela. ibhalansi yokuhlukanisa enezingqimba zokucushwa kwamandla.

2 Uhlelo lweMetallurgical

Izigayo eziginqikayo kanye nama-arc furnaces kagesi yimithwalo ye-impulse ejwayelekile kakhulu. Ukusebenzisa isihlungi se-mcr+fc ukuze uthole isinxephezelo samandla asebenzayo ashukumisayo kungathuthukisa kakhulu isici samandla, kunciphise ukuguquguquka nokucwayiza kwamandla kagesi, kuqede ukungcoliswa kwe-harmonic, kuthuthukise kakhulu ikhwalithi yamandla, kuthuthukise isici sokuphepha sohlelo lokuphakelwa kwamandla, kunciphise ukusetshenziswa kwamandla ngeyunithi ngayinye yokukhiqiza, futhi kuthuthukise umkhiqizo. izinga.

3 Umzila Wesitimela Ogesi

Uloliwe osebenza ngogesi usebenzisa imodi yokuphakelwa kwamandla esigaba esisodwa. Ngenxa yokungahleliwe kwesitimela, ukulayishwa kwesiteshi esingaphansi kokudonsa kunezici zomthwalo womthelela wesigaba esisodwa, nokuguquguquka okuvamile komthwalo kanye nokuqukethwe okuphezulu kwe-harmonic. Akunakwenzeka ukuthola isinxephezelo sesici samandla aphezulu ngokusebenzisa imodi yesinxephezelo esingaguquki elula. Uma i-MCR enamandla afanele ifakwe ngesisekelo sesekhethi yesihlungi se-FC enomthamo owanele, isinxephezelo sesici samandla aphezulu singafinyelelwa noma nini, ukushintshashintsha kwamandla kagesi kungancishiswa futhi izinga likagesi lingathuthukiswa.

Izici zomthwalo wesigaba esisodwa sikaloliwe osebenza ngogesi nazo ziletha izinkinga ezingathi sína zengxenye ephezulu yokulandelana engemihle esiteshini saso esiphezulu sokuphakelwa kukagesi, futhi kuholele nasesenzweni sokuvikela ukulandelana okungekuhle kwezitshalo zikagesi neziteshi ezincane. Ngokufaka izihlungi ze-mcr+fc kulezi ziteshi ezincane kanye nokusebenzisa isu lokulawula ukuhlukaniswa kwesigaba ngokwendlela yakwa-Steinmetz, le nkinga ingaxazululwa ngendlela efanele, futhi ingaxhunywa ngokuqondile nohlelo lokuphakelwa kwamandla ka-110 kV ukuze kunxeshezelwe, ngaphandle kokutshalwa kwezimali kwe ama-transformers aphakathi, indawo ephansi incane, futhi ukulahlekelwa kwemishini ngokwayo kungancishiswa ngaphezu kuka-70%.
