Yini i-11kVI-Vakuum-Leistungsschalter?
AnI-11kV vacuum circuit breaker (VCB)luhlobo lwe-switchgear kagesi eklanyelwei-voltage emaphakathi (MV)izinhlelo zokusebenza, ezisebenza ngokuyinhloko ku-11,000 volts. ukucisha i-arc ngokushesha, ukunciphisa ukuguguleka kokuxhumana, nempilo ende yesevisi.
Ngokungafani nama-breaker circuit avamile noma kawoyela, ama-circuit breaker afaka othintana nabo kusiphazamisi se-vacuum.
Izindawo Zokusebenza zama-11kV VCBs
11kV vacuum circuit breakerasetshenziswa kakhulu ezimbonini nasezimbonini ezahlukahlukene ezidinga izixazululo eziqinile neziphephile zokulawula amandla:
- Izinhlelo zokusabalalisa ugesiezinsizeni naseziteshini ezincane
- Izitshalo zezimboniukulawula imoto nokuvikelwa kwemishini esindayo
- Izakhiwo zezentengiselwano, njengezibhedlela nezikhungo zedatha
- Amapulazi wamandla avuselelekayo, okuhlanganisa ukufakwa komoya kanye nelanga
- Ukufakwa kukagesi kuloliwekanye nezinhlelo ze-metro
Lawa ma-breaker abaluleke kakhuluama-switchgear panel angaphakathikanyekompakte Unterstationen, lapho isikhala, ukuphepha, nokusebenza ngaphandle kokulungisa kubalulekile.
Amathrendi Embonini Nokwakheka Kwezwe Lobuchwepheshe
Ngokombiko kaResearchAndMarkets, imakethe ye-circuit breaker kulindeleke ukuthi ikhule ku-CAGR ye6.2% kusukela ngo-2024 kuya ku-2030, ngobuchwepheshe be-vacuum obubambe iqhaza elikhulu ngenxa yokusebenza kwayo okuhlanzekile nezikhawu zesevisi ezinde. igridi ehlakaniphileizinhlelo zokusebenza ngenxa yesikhathi sazo sokuphendula esisheshayo namandla okuhlanganisa nama-relay okuvikela edijithali.
Ukwengeza, izinhlangano ezilawulayo ezifana neIEEMAkanyeI-IECbaye babeka izimiso eziqinile zokuthobela i-MV switchgear, okwenza izixazululo ezisekelwe ku-vacuum zibe ngcono ngenxa yokuphepha kwazo kwemvelo nokuthembeka.
