Ukusebenza kwegumbi lokucisha i-arc ye-vacuum kunquma ukusebenza kwe-contactor, futhi izici zomshini ze-contactor ngokwayo ziphinde zinqume ukusebenza kwegumbi lokucisha i-arc ye-vacuum. Ukuthi ukusebenza kwe-vacuum contactor kuyahlangabezana yini nezidingo ikakhulukazi kuncike ekutheni izici zayo zokusebenza ziyahlangabezana yini nezidingo. yegumbi lokucisha i-vacuum arc elihambisanayo.
Okokuqala, ukubuka kokuqala kwengcindezi yokuxhumana.Lapho i-vacuum arc yokucima i-arc yenza ngaphandle kwamandla angaphandle, othintana nabo abaguquguqukayo bavala othintana nabo be-static ngaphansi kwesenzo sokucindezela komkhathi, okubizwa ngokuthi amandla e-autistic.Ubukhulu bamandla buncike endaweni ephambanayo ethekwini lombhobho.Ngokuvamile, amandla okuvala awakwazi ukuqinisekisa ukuthintana kukagesi okufanelekayo phakathi kokuxhumana okuguquguqukayo nokumile kwegumbi lokucisha i-arc ye-vacuum, futhi ukucindezela kwangaphandle kungaphezu kwamandla.Ubukhulu balokhu kucindezela buncike ezintweni ezintathu: a.Isilinganiso samanje segumbi le-arc;b.Izinto zokuxhumana zegumbi le-arc;c.Ukwehliswa kukagesi phakathi koxhumana nabo abaguquguqukayo nabaqinile lapho igumbi le-arc livaliwe.Ngokwalezi zici ukukhetha ukucindezela okusetshenzisiwe okufanelekile, amandla okuvala kanye nokucindezela kwangaphandle okuphezulu kubizwa ngokuthi ingcindezi yokuxhumana yekhanda lokuxhumana, elibizwa nangokuthi ingcindezi yokugcina.
2. Indima yengcindezi yokugcina ku-contactor.Ukucindezela kokugcina okunengqondo, Qinisekisa ukumelana nokuxhumana okufanelekayo phakathi koxhumana nabo abaguquguqukayo nabaqinile begumbi lokucima i-arc, Ukumelana nokuxhumana kungalinganiswa nge-resistor yesifunda;Ingcindezi yokugcina enengqondo, Ingakwazi ukuhlangabezana nezidingo zokuzinza kokushisa okuguquguqukayo kwegumbi lokucisha i-arc ye-vacuum, Ingakwazi ukunqoba ukucasuka phakathi koxhumana nabo esimweni esiphezulu samanje, Ukuqinisekisa ukuvalwa okuphelele ngaphandle kokulimala, Okusho ukuthi, othintana nabo ngeke banamathele ukufa;Ingcindezi yokugcina enengqondo, Inganciphisa ukuncishiswa, Amandla omthelela abangela ukuthintana lapho ivaliwe, Amunywe amandla anamandla okunwebeka;Ingcindezi yokugcina enengqondo, Ivumela ukushintsha izici, Lapho ingcindezi yokugcina ihlangabezana nezidingo, Ukucindezelwa kwentwasahlobo yokuxhumana nakho kukhulu, Amandla anamandla okunwebeka nawo makhulu, Ukwandisa isivinini sokuqala sesango lokushintshwa, Yehlisa isikhathi se-arc evuthayo futhi thuthukisa umthamo wokushintsha.
Okwesithathu, incazelo kanye nomsebenzi we-overtravel.Noma yikuphi ukushintshwa kwe-vacuum kuvaliwe kumodi ye-overstroke, uma ivaliwe, othintana nabo abaguquguqukayo abakwazi ukuya phambili ngemva kokuxhumana nabathintana nabo be-static, kodwa ukucindezela phakathi kothintana nabo abaguqukayo kuyadingeka.Lokhu kucindezela kutholwa othintana naye. intwasahlobo.Lapho ukunyakaza nokunyakaza kungqubuzana, amandla entwasahlobo yokuxhumana azoqhubeka nokunyakaza.Ibanga lokufuduka ngesikhathi sokunyakaza yi-stroke yokucindezela kwentwasahlobo yokuxhumana, okuyi-overstroke.Ngaphezu kokwandisa isivinini sokuqala sokushintsha, i-overstroke inemisebenzi emibili ebalulekile: a.Amandla entwasahlobo yokuxhumana adluliselwa ekucindezelweni kokuxhumana phakathi koxhumana nabo ukuze kuhlangatshezwane nezidingo zokusebenza;b.Ngemuva kokusebenza isikhathi eside kwe-contactor, othintana nabo bazoshisa futhi banciphise ukushuba okuphelele koxhumana nabo.Uma i-overstroke enengqondo iqinisekisiwe, ukucindezela okuthile kwetheminali kungenza othintana nabo be-vacuum basebenze ngendlela evamile.Eqinisweni, i-spring pressure yokuxhumana inikeze ukucindezelwa kwesimo se-contactor switch, okuwukuvala umzuzu wokuxhumana, ukufinyelela inani lokucindezela kwangaphambili ukunciphisa ukugxuma okuvala, lapho ukunyakaza kwe-overstroke iphela, ingcindezi yokugcina iphinde ihlangabezane nezidingo zokuklama.
Okwesine, incazelo yesikhathi sokuvala nesikhathi sokuvala kanye nomthelela wobude besikhathi ekusebenzeni kokushintsha.
