Yini i-11kv vacuum contantror?
SebuahI-11kvUKontaktor VakumUhlobo lwe-medium-voltage switch esetshenziselwe ukuxhuma kaningi futhi unqamule imibuthano kagesi ngaphansi komthwalo. Ukuphazamiseka kwe-Vacuum, enikeza amakhono okuqothulwa kwe-ARC aphakeme kanye nempilo esheshayo yokusebenza.
Laba baxhumana nabo bakulungele ikakhulukaziUkushintsha njaloIzicelo futhi zizothuthukiswa ukusebenzaIzinhlelo eziphakathi zamandla, ngokuvamile kusuka ku-6.6KV kuya ku-12kv.
Izicelo ze-11KV Vutuum Oxhumana Nabaxhumana
Abaxhumana nabo bakwa-11kv Vacuum basetshenziswa ezinhlobonhlobo zezimboni laphoUkushintshwa kwe-medtage ephakathi nendawokubalulekile.
- Izikhungo Zokulawula Izimoto (MCCs)Okwezimoto ezinkulu ezimayini, zensimbi, kanye nezitshalo ze-petrochemical

Izitayela Zemakethe Nentuthuko Yezobuchwepheshe
Ngokusho kwe-IEEE kanye nemibiko ehlukahlukene yezimboni, ukutholwa kweUbuchwepheshe bokushintsha kwe-vacuumKuzinhlelo eziphakathi nendawo ezisebenza ngamandla akhula ngokushesha okukhulu. $ 120 billion ngo-2030, nabaxhumana nabo be-vacuum badlala indima enkulu ngenxa yaboisikhathi eside sokuphila,ukulungiswa okuncaneudongaubungane bezemvelo.
Imibiko evela ku-ABB ne-Schneider Electric futhi baqokomisa ukushintshwa kwabaxhumana nabo abahlaselwa umoya ukuzeAmamodeli asungula iziphazamisela, njengoba benikela ngokulawula i-ARC engcono, ukusebenza okuphephile, kanye nokuhambisana namazinga wesimanje wegridi afanaIEC 62271-106.

Ungayikhetha kanjani i-11kv vacuum oxhumana naye ofanele
Ukukhetha oxhumana naye ofanele kuncike ku:
- Ukulayisha izici: I-Indective (Motors), Capacive (Amabhange eCapacitor), noma amelana
- Ukushintsha imvamisa: Amanani aphezulu omjikelezo adinga oxhumana nabo abahlala isikhathi eside
- Lawula ukuhambisana kwe-voltage: Qinisekisa ukuhlanganiswa nezinhlelo zokulawula (e.g., PLCS)
- Ukuhlelwa kwephaneli nendawo ekhuphukayo: Khetha amamodeli acwebile ngezicelo ezicindezelwe isikhala
- Ukuhambisana nokuphepha: Hlala ukhetha amamodeli ahlolweIEC 62271-106u-ataleI-ANSI C37
Ithiphu Yesazi: Ezihlotsheni zezimoto nge-inrush ephezulu yamanje, khetha i-vacuum contamer ngeI-High Wenger Pempelis kanye ne-Arc Shield Designukuqinisekisa ukuqala okuphephile.
Izinzuzo zokusebenzisa i-11kv Vacuum Intantso
- Isikhathi sokuphila eseluliwe: Ukukhuthazela okuphakathi kwemishini nokusebenza ngogesi
