6-220kV high voltage Current Limited reactor

Ama-reactor amanje akhawulelayo ayingxenye ye-inductive ekhawulela ukushintshana kwe-inrush current, i-harmonic ye-oda eliphezulu kanye nephutha lamanje lesifunda esifushane ohlelweni. Ama-reactor amanje anomkhawulo enziwe ngekhoyili yethusi noma nge-aluminium. Izindlela zokupholisa zihlanganisa uhlobo olomile lwe-Air Core kanye nohlobo lokucwiliswa uwoyela.

Ngokuvamile isetshenziselwa imigqa yokusabalalisa. Iziphakeli zegatsha ezivela ebhasini elifanayo zivame ukuxhunyaniswa ne-reactor yamanje enomkhawulo ukuze kukhawulwe amandla wesifunda esifushane sesiphakeli futhi kugcinwe ugesi webhasi, ukuze ungabi phansi kakhulu ngenxa yesiyingi esifushane sesiphakeli.

Ama-reactor amanje akhawulayo asetshenziswa kugridi yamandla empeleni ikhoyili yomoya ngaphandle kokusebenza kazibuthe. Ingahlelwa ngezindlela ezintathu zokuhlanganisa: mpo, ovundlile kanye namazombezombe. Uma isifunda esifushane senzeka ohlelweni lwamandla, inani elikhulu le-short circuit current lizokwenziwa. Kunzima kakhulu ukugcina ukuzinza okuguquguqukayo nokuzinza kokushisa kwemishini kagesi ngaphandle kokuvinjelwa. Ngakho-ke, ukuze kuhlangatshezwane nezidingo zokuphulwa kwamandla kwamanye ama-circuit breaker, ama-reactors avame ukuxhunywa ochungechungeni kuma-circuit breaker aphumayo ukuze akhuphule i-impedance ye-short-circuit kanye nomkhawulo wamanje we-short-circuit current.

Ngenxa yokusetshenziswa kwe-reactor, uma kwenzeka i-short circuit, ukwehla kwamandla kagesi kuma-current limiting reactors kukhulu, ngakho futhi kudlala indima ekugcineni izinga likagesi webhasi, ukuze ukushintshashintsha kwamandla kagesi ebhasi kube kuncane, okuqinisekisa ukusebenza. ukuzinza kwempahla kagesi yomsebenzisi kulayini ongelona iphutha.

Ukubalwa nokuhlelwa komthamo

Ifomula yokubala yomthamo we-reactor ithi: SN = UD% X (phezulu / √ 3) x In, kanye neyunithi ye-in ithi Ampere.

Inhloso yokufaka ama-Current-limiting reactors ezimbonini zikagesi naseziteshini ezincane ukukhawulela i-short-circuit current ukuze izinto ezisebenza ngogesi zikwazi ukukhethwa ngokwezomnotho nangokunengqondo. Ama-reactor angahlukaniswa abe ama-reactors alayini, ama-reactor amabhasi, nama-loop reactors we-transformer ngokuya ngezindawo ezihlukene zokufaka nemisebenzi.

(1) I-reactor yomugqa. Ukuze usebenzise i-breaker circuit light futhi unciphise ingxenye ephambanayo yekhebula yokuphakelayo, i-reactor yolayini ivamise ukuxhunywa ngochungechunge kusiphakeli sekhebula.

(2) I-reactor yebhasi. I-reactor yebhasi ixhunywe ochungechungeni esigabeni sebhasi le-voltage ye-generator noma ohlangothini lwe-low-voltage ye-transformer eyinhloko. Isetshenziselwa ukukhawulela i-short-circuit current ngesikhathi se-short-circuits ngaphakathi nangaphandle kwesitshalo. Ibizwa nangokuthi i-reactor yesigaba sebhasi. Uma isifunda esifushane senzeka kulayini noma ebhasini elilodwa, singakhawulela i-short-circuit current enikezwa elinye ibhasi. Uma izidingo zingahlangatshezwana nazo, ukufakwa kwe-reactor emugqeni ngamunye kungashiywa ukuze kongiwe ukutshalwa kwezimali kobunjiniyela, kodwa kunomthelela omncane wokukhawulela i-short-circuit current.

(3) Transformer loop reactor. Ifakwe kumjikelezo we-transformer ukukhawulela i-short-circuit current ukuze i-transformer circuit isebenzise ama-breaker circuit light.
