Isakhiwo sama-vacuum circuit breakers

i-vacuum circuit breaker iyiswishi kagesi esetshenziselwa ukulawula, ukuvikela nokuhlukanisa izifunda zikagesi. Ngokungafani ne-circuit breakers yendabuko ethembele ku-oyili noma igesi njengendawo yokucisha i-arc, ama-vacuum circuit breakers asebenzisa igumbi lokucisha i-arc ye-vacuum njengendlela yokucisha i-arc ekhiqizwa ngesikhathi senqubo yokuphuka kwesifunda. Enye yezinzuzo eziyinhloko ze-vacuum circuit breaker yikhono layo lokuvula isifunda ngokushesha, ukunciphisa umonakalo nokuvimbela izingozi zikagesi.

Ukwakheka kwesakhiwo se-vacuum circuit breaker kuvame ukuba nezingxenye ezintathu eziyinhloko: igumbi lokucisha i-arc, indlela yokusebenza kanye nesici sokulawula. I-interrupter iqukethe oxhumana nabo bensimbi ababili abahlukaniswe ngaphakathi kwegumbi le-vacuum. Lapho i-circuit breaker ivulwa, i-vacuum medium enamandla aphezulu e-dielectric iqinisekisa ukufudumala phakathi koxhumana nabo. Kodwa-ke, lapho kwenzeka iphutha futhi i-circuit breaker idinga ukukhubeka, oxhumana nabo bayahlangana, baqale inqubo yokucisha i-arc.

Indlela yokusebenza inesibopho sokuvula nokuvala i-circuit breaker ngaphansi kwezimo ezijwayelekile nezingalungile. Le ndlela isebenzisa ubuchwepheshe obuhlukahlukene njengamandla agciniwe (izipringi) noma ama-electromagnetic actuator ukukhiqiza amandla okusebenza adingekayo. Ngakolunye uhlangothi, izinto zokulawula ziqinisekisa ukuhlanganiswa okufanele kanye nokuvumelanisa kwezindlela zokusebenza. Zihlanganisa ukushintsha okusizayo, ama-relay kanye nama-timer futhi zenza imisebenzi efana nokusebenza kwe-trip coil, ukutholwa kwamaphutha kanye nokuhlanza amaphutha. Lezi zindlela zokukhiya ezixhumene ziqinisekisa ukusebenza okuphephile nokuthembekile kwe-vacuum circuit breaker.

Ngamafuphi, ama-vacuum circuit breaker ayingxenye ebalulekile yezinhlelo zikagesi, aqinisekisa ukuvikelwa kwemishini nabasebenzi emaphutheni kagesi. Isakhiwo se-vacuum circuit breaker sakhiwe yigumbi lokucisha i-arc, indlela yokusebenza kanye nesici sokulawula, esisebenzisana ukuze kufezwe ukuphuka kwesekethe okuphumelelayo kanye nokucisha i-arc. Ukuqonda izingxenye nemisebenzi yayo kusiza onjiniyela nochwepheshe ukuba benze izinqumo ezinolwazi lapho beklama, befaka, futhi begcina izinhlelo zikagesi ezindaweni zokuhlala, zezentengiselwano, kanye nezezimboni. Ngokusebenzisa izinzuzo eziningi zama-vacuum circuit breaker, singaqinisekisa ingqalasizinda yamandla ephephile nethembekile emhlabeni.
