Isingeniso kuAbaphula umthetho we-vacuumI-Vacuum Breaker uhlobo olubalulekile lokuphuka kwesekethe okuphazamisa ukuhamba kwamanje ku-Voltage kagesi kagesi usebenzisa i-vacuum njenge-arc-deciting medium.
Basebenza kanjani ama-vacuum breakerIndlela eyisisekelo ye-vacuum breaker ilele kuyoIgumbi le-Vacuum Artingter.
- Ukuhlukaniswa kokuthintana: Lapho kutholwa iphutha, indlela eyedlule iphoqa othintana nabo ngaphakathi kwegumbi le-vacuum evaliwe.
- Ukwakheka kwe-arc: Njengoba othintana nabo behlukana, amafomu we-arc ngenxa ye-ionization yama-metal vapors.
- Ukuqothulwa kwe-ARC: E-vacuum, azikho ama-molecule egesi ukuze axhase i-arc.
- Ukuvuselelwa kwe-dielectric: I-vacuum ivumela ukululama okusheshayo kwe-dielectric, okwenza uhlelo lulungele ukusebenza ngokushesha.
Izicelo ze-vacuum breakersAma-vacuum circuit breakers asetshenziswa ngokujwayelekile ku:
- I-Medium-voltage switchgear (1 kv kuya ku-38 kv)
- Izinhlelo zamandla zokusabalalisa ezitshalweni zezimboni
- Ukufakwa kwamagridi wosizo
- Izicelo zezimayini nezasolwandle
- Izinhlelo zamandla avuselelekayo
Ubukhulu babo obuhlanganisiwe, ukulungiswa okuncane, futhi impilo ende ibenze balungele imisebenzi ebucayi obubucayi.
Umhlahlandlela we-Breaker efakwe ku-Industrial Switchchgear Panel "Class =" WP-image-1284 "/>Izitayela Zemakethe Nokumukelwa KwezimboniNgokuvumelana neIeeena-Uyema, Ubuchwepheshe be-Vacuum Breaker buye baba yindinganiso evelele yezinhlelo zamandla okusebenza kwamandla aphakathi emhlabeni jikelele.
- Ukwanda kwesidingo kusuka ku-Smart Grid Expnsion
- Ukufakwa okuvuselelayo ezitshalweni zamandla avuselelekayo
- Ukushintshwa kokuguga kwe-SF6-based Breakers ngokulandela imvelo
Abakhiqizi bathandaAbisa,Schneider Electric, futhiNokiaUqhubeke nokusungula izinto zokuxhumana, ukwakheka kwe-actuator, kanye nokuhlanganiswa kwedijithali.
Amapharamitha Ezobuchwepheshe nokuqhathanisa
| Ubuso | Umfutho we-vacuum | I-SF6 Breaker |
|---|---|---|
| I-arc icima i-medium | Mba okuvubalisa ndawonye | Isibabule Hexafluoride (SF6) |
| Isikhathi sokuvuselelwa kwe-dielectric | Ngokushesha kakhulu | -Ngeqile |
| Umthelela wezemvelo | Namunye | I-High (Greenhouse Gas) |
| Izidingo zokulungiswa | -Ehlile | Okuphakathi nendawo kuya phezulu |
| I-voltage ejwayelekile yohlelo lokusebenza | 1 KV kuya ku-38 kV | 72.5 kV nangaphezulu |
Izinzuzo ngaphezu kwendabuko yendabuko
- Akukho ukugcwaliswa kwegesi okudingekayo
- Impilo ende emishini(~ 10,000 imisebenzi noma ngaphezulu)
- Ukuqothulwa kwe-arc okusheshayo nokulahleka kwamandla aphansi
- I-compact ne-modular design
Lezi zinzuzo zenze ama-vacuum breakers ancamela kakhulu kumanethiwekhi kagesi asemadolobheni kanye nezimboni.
Umhlahlandlela wokuthenga kanye namathiphu wokukhethaLapho ukhetha i-vacuum breaker:
- Qondanisa i-voltage ne-rating yamanjeohlelweni lwakho
- Khetha phakathiIzinhlobo ezilungisiwe noma ezihoxisiweKuya ngezidingo zokulungiswa
- Khetha amamodeli ngeUkuxilongwa kwedijithaliUkuhambisana kwegridi ehlakaniphile
- QinisekisaUkuhambisana ne-IEC 62271 noma ama-ANSI / IEEE C37.04 Amazinga
Isigaba se-FAQ
I-vacuum inikezela ngokufakwa okuhle kakhulu kanye namandla okuqothulwa kwe-arc ngaphandle kokwethula amagesi ayingozi, okwenza ukuba i-breaker ibe lula futhi isebenze kahle.
Ngokuvamile, ama-vacuum breakers asetshenziswa ezinhlelweni eziphakathi nendawo.
Badinga ukulungiswa okuncane, imvamisa ngemuva kokusebenza okungu-10,000 noma ngaphezulu, okwenza babe fanele ukuthola izindawo ezifunwayo.
