Kuchita kwa vacuum arc kuzimitsa chipinda kumatanthawuza kugwira ntchito kwa contactor, ndi mawonekedwe a makina a contactor okha amatsimikiziranso ntchito ya vacuum arc kuzimitsa chipinda. wa chipinda chozimira cha vacuum arc yofananira.
Choyamba, kuyang'ana koyamba pa kukhudzana kwa pressure.Pamene chipinda chozimitsa cha vacuum arc chikuchita popanda mphamvu yakunja, kukhudzana kwamphamvu kumatseka ndi kukhudzana kwa static pansi pa mphamvu ya mlengalenga, yomwe imatchedwa autistic force.Kukula kwa mphamvu kumadalira pa doko lodutsa gawo la mavuvu.Nthawi zambiri, mphamvu yotseka siyingatsimikizire kukhudzana kwamagetsi koyenerera pakati pa zolumikizana zosunthika komanso zosasunthika za chipinda chozimitsira cha vacuum arc, ndipo kukakamiza kwakunja kumakhala kwakukulu.Mphamvu yovotera ya chipinda cha arc;b.The arc chipinda cholumikizira zinthu;c.Kuthamangitsidwa kwa magetsi pakati pa kukhudzana kwamphamvu ndi kosasunthika pamene chipinda cha arc chatsekedwa.Malinga ndi zinthu izi kusankha kukakamiza koyenera kogwiritsidwa ntchito, mphamvu yotsekera ndi kuthamanga kwa kunja kwapamwamba kumatchedwa kukhudzana kwa mutu wokhudzana ndi mutu, womwe umatchedwanso kuthamanga kwapakati.
2. Udindo wa kupanikizika kwa terminal pa contactor.Kuthamanga koyenera koyenera, Kuonetsetsa kuti oyenerera kukhudzana kukana pakati pa okhudza mphamvu ndi malo amodzi kukhudzana arc kuzimitsa chipinda, Contact kukana akhoza kuyeza ndi dera resistor;Kuthamanga koyenera, Ikhoza kukwaniritsa zofunikira za kutentha kwamphamvu kwa chipinda chozimitsa cha vacuum arc, Ikhoza kugonjetsa kukhumudwa pakati pa omwe akulumikizana nawo pakalipano, Kuonetsetsa kuti kutsekedwa kwathunthu popanda kuwonongeka, ndiko kuti, olankhulana nawo sangagwirizane. imfa;Kupanikizika koyenera, Kungathe kuchepetsa kuchepetsedwa, Mphamvu yomwe imayambitsa kukhudzana ikatsekedwa, Yotengedwa ndi mphamvu yotheka;Kuthamanga koyenera kwa terminal, Pothandizira kusintha mawonekedwe, Kuthamanga kwa terminal kukakwaniritsa zofunikira, Kuphatikizika kwa masika kumakhalanso kwakukulu, Mphamvu zotanuka zimathanso kukhala zazikulu, Kuchulukitsa liwiro loyambira pachipata chosinthira, Kuchepetsa nthawi yoyaka ndi arc. onjezerani mphamvu yosinthira.
Chachitatu, tanthawuzo ndi ntchito ya overtravel.Any vacuum switch imatsekedwa mu njira yowonongeka, ikatsekedwa, kukhudzana kwamphamvu sikungathe kupita patsogolo pambuyo pokhudzana ndi ogwirizanitsa osasunthika, koma kupanikizika pakati pa kukhudzana kwamphamvu kumafunika. masika.Pamene kusuntha ndi kuyenda zikuwombana, mphamvu pa kasupe wolumikizana idzapitirizabe kuyenda.Mtunda wosasunthika panthawi ya kayendetsedwe kake ndi kupanikizika kwa kasupe wa kukhudzana, komwe kumakhala kuwonjezereka.Kuphatikiza pa kuwonjezereka kwa liwiro loyamba la kusintha, overstroke ili ndi ntchito ziwiri zofunika: a.Mphamvu ya kukhudzana kasupe imafalikira ku kukhudzana kukakamiza pakati pa kukhudzana kuti akwaniritse zosowa za ntchito;b.Pambuyo pa ntchito yaitali ya contactor, kulankhula adzawotcha ndi kuchepetsa makulidwe okwana kulankhula.Ngati kupitilira muyeso kuli kotsimikizika, kupanikizika kwina kungapangitse kuti ma vacuum azitha kugwira ntchito moyenera. M'malo mwake, kukhudzana kwamakasitomala kwapereka kukanikiza kwa cholumikizira cholumikizira, chomwe ndikutseka nthawi yolumikizana, kufikira mtengo wa prepressure kuti muchepetse kutseka kotseka, pamene kusuntha kwa overstroke kumatha, kuthamanga kwapakati kumakwaniritsanso zofunikira za mapangidwe.
Chachinayi, tanthawuzo la nthawi yotseka ndi nthawi yotseka komanso zotsatira za kutalika kwa nthawi pakusintha ntchito.
