6-220kV amandla ombane aphezulu Current Limited reactor

I-reactors yangoku yokunciphisa i-inductive component ethintela i-switching inrush current, i-high-order harmonic kunye ne-short-circuit fault current kwinkqubo. I-reactors yangoku yokunciphisa yenziwe ngekhoyili yobhedu okanye i-aluminium. Iindlela zokupholisa ziquka uhlobo lwe-Air Core olomileyo kunye nohlobo lokucwiliswa kweoli.

Ngokuqhelekileyo isetyenziselwa imigca yokuhambisa. Abaxhasi besebe abasuka kwibhasi enye bahlala bedityaniswa ne-reactor yangoku enomda ukukhawulela i-short-circuit current ye-feeder kunye nokugcina umbane webhasi, ukuze ungabi phantsi kakhulu ngenxa ye-short-circuit ye-feeder.

Unyino lwangoku lwereactor ezisetyenziswa kwigridi yamandla ngokwesiseko Ikhoyili yoMoya ngaphandle kwesixhobo sokuqhuba samagnetic. Inokucwangciswa kwiifom zendibano ezintathu: ngokuthe nkqo, tye kunye ne-zigzag. Xa isiphaluka esifutshane senzeke kwisistim samandla, ixabiso elikhulu lombane omfutshane liya kuveliswa. Kunzima kakhulu ukugcina ukuzinza okuguquguqukayo kunye nokuzinza kwe-thermal yezixhobo zombane ngaphandle kwesithintelo. Ke ngoko, ukuze kuhlangatyezwane neemfuno zokuqhawuka kwamandla kwezinye ii-breakers zesekethe, ii-reactors zihlala ziqhagamshelwe kuthotho kwii-breakers zesekethe eziphumayo ukunyusa i-impedance ye-short-circuit kunye nokunciphisa i-short-circuit current.

Ngenxa yokusetyenziswa kwereactor, kwimeko yesekethe emfutshane, ukuhla kwamandla ombane kwiireactors zangoku ezinciphisayo kukhulu, ngoko ke ikwadlala indima ekugcineni inqanaba lombane webhasi, ukuze ukuguquguquka kwamandla ombane ebhasini kuncinci, kuqinisekisa ukusebenza. ukuzinza kwesixhobo sombane somsebenzisi kumgca ongenasiphako.

Ukubala kunye nokuhlelwa komthamo

Ifomula yokubala yomthamo wereactor yile: SN = UD% X (phezulu / √ 3) x Ngaphakathi, kunye neyunithi ye-in yi-Ampere.

Injongo yokufakela i-Curent-liming reactors kwimizi-mveliso yombane nakwizikhululo ezincinci kukucutha umsinga omfutshane ukuze izixhobo zombane zibe nokukhethwa ngokoqoqosho nangengqiqo. Iireactors zinokwahlulwa zibe zizixhobo zombane, ii-reactors zebhasi, kunye ne-transformer loop reactors ngokweendawo ezahlukeneyo zofakelo kunye nemisebenzi.

(1) Umgca we-reactor. Ukuze usebenzise i-breaker circuit lighter kunye nokunciphisa icandelo lomnqamlezo wekhebula le-feeder, i-reactor yomgca idla ngokudityaniswa kwi-series kwi-cable feeder.

(2) I-reactor yebhasi. I-reactor yebhasi idibaniswe kwichungechunge kwicandelo lebhasi ye-voltage ye-generator okanye icala eliphantsi le-voltage ye-transformer enkulu. Isetyenziselwa ukunciphisa umsinga wesekethe emfutshane ngexesha leesekethe ezimfutshane ngaphakathi nangaphandle kwesityalo. Ikwabizwa ngokuba yi-reactor yecandelo lebhasi. Xa isiphaluka esifutshane senzeke kumgca okanye kwibhasi enye, sinokukhawulela umsinga omfutshane obonelelwa ngenye ibhasi. Ukuba iimfuno zinokufezekiswa, ukufakwa kwe-reactor kumgca ngamnye kunokushiywa ukuze kugcinwe utyalo-mali lobunjineli, kodwa kunempembelelo encinci yokunciphisa i-short-circuit current.

(3) Isixhobo sokuguqula iluphu yenguqu. Ifakwe kwi-transformer circuit ukukhawulela i-short-circuit current ukwenzela ukuba i-transformer circuit ikwazi ukusebenzisa i-light circuit breakers.
