I-HYTBBT i-voltage-adjusting kanye ne-capacity-adjusting high-voltage reactive power device

incazelo yomkhiqizo

Njengamanje, umkhakha wamandla ubheka ukubaluleka okukhulu ekongeni amandla kanye nokunciphisa ukulahlekelwa.Kusukela ekuphathweni kwamandla kagesi kanye namandla asebenzayo, kutshalwe imali enkulu ukuthuthukisa isofthiwe yokuphatha amandla kagesi eningi kanye ne-reactive power.I-VQC, i-on-load tap change, ibhange le-Reactive power compensation shunt capacitor nezinye izinto zokusebenza, ikhwalithi kagesi ithuthukiswe ngempumelelo.Kodwa-ke, ngenxa yokuhlehla kwezindlela zokulungisa amandla asebenzayo kanye nezinkinga ezinjengokugeleza kwe-overvoltage, i-overcurrent, kanye nesikhathi sokuphila ekusebenzeni kwama-capacitor, isoftware yokuphatha amandla kagesi kanye ne-reactive ayikwazi ukudlala indima yayo efanele, futhi ayikwazi njalo ukugcina izinkomba ezidingekayo ze-voltage kanye amandla asebenzayo.Izinzuzo ezifanele zezomnotho nezobuchwepheshe azikwazi ukufinyelelwa, futhi amandla amathuluzi angeke asetshenziswe ngokugcwele.

Ihlose ukubuyela emuva kwe-voltage kanye nezindlela zokulungisa amandla asebenzayo, inkampani yethu isungule uhlobo olusha lwamandla kagesi wesiteshi esincane namandla asebenzayo okulungisa okuzenzakalelayo ngesisekelo sokumunca kakhulu ubuchwepheshe obusha ekhaya naphesheya.Amandla okukhiphayo ashintshwa ngokulungisa i-voltage emikhawulweni yomibili ye-capacitor, exazulula izinkinga ze-overvoltage kanye ne-inrush current ekusebenzeni kwe-capacitor, futhi iguqule ukulungiswa kwe-hysteresis ekulungiseni kwesikhathi sangempela.I-voltage yesiteshi esingaphansi kanye nedivayisi yokulungisa ezenzakalelayo yamandla asebenzayo ingase futhi iguqule i-parallel capacitor engaguquki ibe idivayisi yesinxephezelo samandla asebenzisekayo alungisekayo.Ukuthandwa nokusetshenziswa kwale mishini kungathuthukisa ngempumelelo izinga lokuphatha lamandla kagesi namandla asebenzayo, okunganciphisa kakhulu ukulahleka komugqa wegridi kagesi, kuthuthukise izinga lamandla, kuthuthukise izinga lokusebenza okuphephile kwemishini, kukhuphule izinzuzo zezomnotho zamabhizinisi anikezela ngogesi. , kanye nokuthuthukisa umthamo wokuphakelwa kukagesi ngaphandle kokwakha izindawo ezintsha zokuphehla ugesi.Ukubamba iqhaza ekuxazululeni isimo esikhona manje sokushoda kwamandla kagesi.

ububanzi besicelo

Imikhiqizo ifaneleka kakhulu kuwo wonke amazinga eziteshi ezincane ezinamaleveli kagesi angu-6KV~220KV, futhi afakwe kumabhasi angu-6KV/10KV/35KV eziteshi ezingaphansi.Imikhiqizo isetshenziswa kakhulu ezinhlelweni zamandla, i-metallurgy, amalahle, i-petrochemical nezinye izimboni ukuthuthukisa ikhwalithi yamandla kagesi, ukwandisa amandla, kanye nokunciphisa ukulahleka komugqa.

Umgomo wedivayisi
Idivayisi yokulungiswa okuzenzakalelayo kwamandla kagesi namandla asebenzayo wesiteshi esincane isebenzisa uxhumano olungaguquki lwama-capacitor ngaphandle kokuhlanganisa, futhi umthamo wokunxephezela we-capacitor uguqulwa ngokushintsha i-voltage kuzo zombili iziphetho ze-capacitor.Ngokomgomo we-Q = 2πfCU2, i-voltage kanye nenani le-C le-capacitor lihlala lingashintshiwe, futhi i-voltage emikhawulweni yomibili ye-capacitor iyashintshwa.Okukhiphayo kwamandla asebenzayo.
Umthamo wayo wokukhipha ungashintsha ukunemba nokujula kokulawulwa kwamandla kagesi ku- (100% ~ 25%) x Q, okungukuthi, ukunemba kokulungiswa nokujula kwama-capacitor kungashintshwa.
Umfanekiso 1 umdwebo we-block wesimiso sokusebenza sedivayisi:

Ukwakhiwa kwedivayisi

Idivayisi yesinxephezelo esizenzakalelayo esilawula amandla kagesi yakhiwe ikakhulukazi izingxenye ezintathu, okuyisilawuli sikagesi, isethi ephelele yama-capacitor kanye nephaneli yokulawula amandla kagesi kanye ne-reactive power.Umdwebo 2 uwumdwebo oyinhloko wohlelo lwedivayisi:

Isilawuli samandla kagesi: Isilawuli sixhuma i-capacitor kubha yebhasi, futhi sishintsha i-voltage ephumayo ye-capacitor ngaphansi kwesisekelo sokuqinisekisa ukuzinza kwe-voltage ye-busbar, ukuze kuqinisekiswe ukuthi umthamo ophumayo we-capacitor uhlangabezana nezidingo zesistimu.Iphaneli yokulawula amandla kagesi kanye ne-reactive power: Ngokwesiginali yokufaka yamanje kanye ne-voltage, ukwahlulela kompompi kuyenziwa, futhi kukhishwa imiyalo yokulungisa ompompi abakhulu be-transformer besiteshi esincane ukuze kulungiswe i-voltage ukuze kuqinisekiswe izinga lokuphasa kwe-voltage yebhasi.Lungisa i-voltage ephumayo yesilawuli se-voltage ukuze ushintshe ukuphuma kwamandla asebenzayo we-capacitor.Futhi inesibonisi esihambisanayo nemisebenzi yesiginali.Umthombo wamandla asebenzayo we-capacitor isethi ephelele.

Izinzuzo zedivayisi

a.Uma kuqhathaniswa nohlobo lokushintsha, isethi eyodwa kuphela yamabhange e-capacitor engaxhunywa ngokuqinile ukuze kutholakale ukuphuma kwesivinini esiyisishagalolunye, futhi ukunemba kwesinxephezelo kuphezulu, okungahlangabezana nezidingo zezinguquko zamandla asebenzayo wesistimu;
