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

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Incazelo emfushane yomkhiqizo:

Isiphazamisi se-vacuum ngokuvamile sinokuthinta okukodwa okugxilile kanye noyedwa onyakazayo, isivunguvungu esivumela umnyakazo walokho kuthintwayo, kanye nezihlangu ze-arc ezivalwe ngengilazi evalwe kahle, indlu ye-ceramic noma yensimbi ene-vacuum ephezulu.Othintana naye onyakazayo uxhunywe umluko oguquguqukayo kumjikelezo wangaphandle, futhi uhanjiswa umshini lapho idivayisi idingeka ukuthi ivule noma ivale.Njengoba umfutho womoya uvamise ukuvala abathintwayo, umshini wokusebenza kufanele ubambe othintana nabo bavule ngokumelene namandla okuvala okucindezela komoya okuvuthela.
Indawo evalekile yesiphazamisi yenziwe ngengilazi noma nge-ceramic.Izigxivizo ze-Hermetic ziqinisekisa ukuthi i-vacuum yokuphazamisa iyagcinwa impilo yonke yedivayisi.Indawo ebiyelwe kufanele ingangeni negesi, futhi akufanele ikhiphe igesi evaleleke.Izivunguvungu zensimbi engagqwali zihlukanisa ivacuum ngaphakathi kwesiphazamisi emkhathini wangaphandle futhi zihambise othintana naye ngaphakathi kwebanga elicacisiwe, ivule futhi ivale iswishi.
Nakuba amanye amadizayini esiphazamisi se-vacuum enokuxhumana okulula kwezinqe, abathintwayo ngokuvamile balolongwa ngezikhala, ama-ridge, noma ama-grooves ukuze kuthuthukiswe ikhono labo lokunqamula imisinga ephezulu.I-arc current egeleza koxhumana nabo abanomumo ikhiqiza amandla kazibuthe kukholamu ye-arc, abangela ukuthi indawo yokuxhumana ye-arc ihambe ngokushesha phezu kokuxhumana.Lokhu kunciphisa ukuguga kokuxhumana ngenxa yokuguguleka kwe-arc, encibilikisa insimbi yokuxhumana lapho kuxhunywana khona.
Ukuminyana komhwamuko kuncike ku-current in the arcing.Ngenxa yokuncipha kwemodi yegagasi lamanje izinga labo lokukhululwa kokuwa komhwamuko nangemva kukaziro wamanje, okuphakathi kuthola amandla ako e-dielectric uma kunikezwe ukuminyana komhwamuko ozungeze abathintwayo abancishiwe.Ngakho-ke, i-arc ayiphindi ibambezeleke futhi ngoba umhwamuko wensimbi ususwa ngokushesha endaweni yokuxhumana.

Lalela:

(1) Izinyathelo zokuvimbela ukugcwala ngokweqile.
(2) Lawula ngokuqinile isivinini sokuvala nokuvula se-vacuum circuit breaker.
(3) Lawula ngokuqinile uhambo lokuxhumana.
(4) Lawula ngokuqinile umthwalo wamanje.
(5) Umjikelezo wokunakekela we-vacuum circuit breaker.
