Umkhiqizo
Isiphazamisi se-vacuum se-low voltage circuit breaker(605)
Incazelo emfushane yomkhiqizo:
Isiphazamisi se-vacuum idivayisi kagesi evacuum esebenzisa i-vacuum ephezulu evala i-arc yokucima umlilo futhi ibona umsebenzi wokucisha wesekethe yamandla ngababili abathintwayo abavalwe ku-vacuum.Lapho inqamula inani elithile lamanje, ngesikhathi sokuhlukaniswa koxhumana nabo abashukumisayo nabaqinile, lamanje liyancipha kuze kube yilapho abathintwayo bavele bahlukane, okuholela ekwenyukeni okukhulu kokumelana phakathi kwama-electrode kanye nokwanda okusheshayo kwezinga lokushisa, kuze kube ukuhwamuka kwensimbi ye-electrode kwenzeka, futhi ngasikhathi sinye, kwakheka amandla enkambu kagesi aphezulu kakhulu, okuholela ekuphumeni okunamandla kakhulu kanye nokuqhekeka kwegebe, okuholela ku-vacuum arc.Lapho i-voltage yefrikhwensi yamandla isondele ku-zero, futhi ngesikhathi esifanayo, ngenxa yokwanda kwebanga lokuvula lokuxhumana, I-plasma ye-vacuum arc ihlakazeka ngokushesha nxazonke.
Isakhiwo
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.
Izivunguvungu zesiphazamisi se-vacuum zivumela ukuthintana okunyakazayo ukuthi kuqhutshwe ngaphandle kwendawo evalekile yesiphazamisi, futhi kufanele kugcine i-vacuum ephezulu yesikhathi eside ngaphezu kwempilo yokusebenza elindelwe yesiphazamisi.Izifutho zenziwe ngensimbi engagqwali enogqinsi luka-0.1 kuya ku-0.2 mm.Impilo yayo yokukhathala ithintwa ukushisa okwenziwa ku-arc.
Ukuze bakwazi ukuhlangabezana nezidingo zokukhuthazela okuphezulu ekusebenzeni kwangempela, ama-bellows ahlala evivinywa ukubekezela njalo ezinyangeni ezintathu.Ukuhlola kwenziwa ekhabetheni lokuhlola elizenzakalelayo ngokugcwele futhi uhambo lulungiselelwa uhlobo olufanele.
