Isiphazamisi se-vacuum se-MV VCB(igobolondo leceramic, I-voltage elinganiselwe: 7.2kV-12kV)

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Incazelo emfushane yomkhiqizo:

Ukutholwa kwe-Vacuum Arc kwe-Vacuum Circuit Breaker
I-vacuum ephezulu inamandla aphezulu kakhulu e-dielectric.Ku-zero yamanje i-arc icishwa ngokushesha okukhulu, futhi amandla e-dielectric asungulwa ngokushesha okukhulu.Lokhu kubuya kwamandla e-dielectric kungenxa yensimbi ehwamukile etholakala endaweni phakathi koxhumana nabo isakazeka ngokushesha ngenxa yokungabikho kwama-molecule egesi.Ngemuva kokuphazamiseka kwe-arc, amandla okuthola kabusha phakathi kwama-microsecond ambalwa okuqala angu-1 kV/µs isekhondi ku-arc current engu-100A.
Ngenxa yesibaluli esishiwo ngenhla se-vacuum circuit breaker, iyakwazi ukuphatha izikhathi zokutakula ezinzima ezihambisana namaphutha omugqa omfushane ngaphandle kobunzima.

Impahla yokuxhumana
Impahla yokuxhumana ye-vacuum circuit breaker kufanele ibe nempahla elandelayo.

Ukusebenza kwe-Vacuum Circuit Breaker
Uma iphutha lenzeka ohlelweni, othintana nabo bephula bayahlukaniswa futhi yingakho i-arc ithuthukiswa phakathi kwabo.Lapho othintana nabo abaphethe njengamanje behlukaniswa, izinga lokushisa lezingxenye zabo zokuxhuma liphezulu kakhulu ngenxa yokuthi kwenzeka ionization.Ngenxa ye-ionization, indawo yokuxhumana igcwele umhwamuko wama-ion aqondile akhishwa kuzinto zokuthintana.

Umjikelezo wokulungisa we-vacuum circuit breaker
I-vacuum circuit breaker inezici zokuthembeka okuphezulu, impilo ende yesevisi kanye nomjikelezo omude wokulondolozwa nokulungisa, kodwa angeke kwenziwe iphutha ukuthi i-vacuum circuit breaker ayidingi ukulungiswa.Umjikelezo wokunakekela kufanele ulawulwe ngendlela evumelana nezimo ngokuvumelana nemithethonqubo efanele futhi uhlanganiswe nezimo zangempela zokusebenza.

Izici

1. I-arc icishiwe esitsheni esivaliwe, futhi i-arc negesi eshisayo ayivezwa.Njengengxenye ezimele, igumbi lokucima i-arc kulula ukulifaka nokuyilungisa.
2. Imvume yokuxhumana incane kakhulu, imvamisa ingaba ngu-10mm, inamandla amancane okuvala, indlela elula nempilo ende yesevisi.
3. Isikhathi sokucisha i-arc sifushane, i-arc voltage iphansi, amandla e-arc mancane, ukulahlekelwa kokuxhumana kuncane, futhi izikhathi zokuphuka ziningi.

Okwedlule: Isiphazamisi se-vacuum se-MV VCB(igobolondo leceramic, I-voltage elinganiselwe: 7.2kV-12kV)

Olandelayo: Isiphazamisi se-vacuum se-MV VCB(igobolondo leceramic, I-voltage elinganiselwe: 7.2kV-12kV)
