Chosokoneza cha vacuum cha otsika ma voltage circuit breaker (604)
Kufotokozera mwachidule za malonda:
M'mabotolo ozungulira, zida zolumikizirana ndi vacuum-interrupter makamaka zimakhala 50-50 copper-chromium alloy.Zitha kupangidwa powotcherera pepala la aloyi yamkuwa ndi chrome pamwamba ndi pansi pampando wokhala ndi mkuwa wopanda mpweya.Zida zina, monga siliva, tungsten ndi tungsten, zimagwiritsidwa ntchito popanga zosokoneza zina.Kulumikizana kwa chosokoneza cha vacuum kumakhudza kwambiri mphamvu yake yosweka, kulimba kwa magetsi komanso kuchuluka kwa kudula komweko.
Vuto la vacuum interrupter limalola kuti cholumikiziracho chiziyendetsedwa kuchokera kunja kwa mpanda wosokoneza, ndipo chiyenera kukhala ndi vacuum yayitali kwa nthawi yayitali pa moyo womwe wosokoneza akuyembekezeka.Mavuvu amapangidwa ndi chitsulo chosapanga dzimbiri chokhala ndi makulidwe a 0.1 mpaka 0.2 mm.Moyo wake wotopa umakhudzidwa ndi kutentha komwe kumachitika kuchokera ku arc.
Kuti athe kukwaniritsa zofunika kuti apirire kwambiri m'zochitika zenizeni, mvuvuzo zimayesedwa pafupipafupi miyezi itatu iliyonse.Mayeso amachitika mu kanyumba kayezero kodziwikiratu koyenda komwe kumasinthidwa ndi mtundu wake.
Magulu ang'onoang'ono osokoneza vacuum poyamba adasonkhanitsidwa ndikumangirira pamodzi mu ng'anjo ya hydrogen-atmosphere.Chubu cholumikizidwa mkati mwa chosokonezacho chinagwiritsidwa ntchito kutulutsa chosokonezacho ndi pampu yakunja yotsekera pomwe chosokonezacho chimasungidwa pafupifupi 400 °C (752 °F).
Nthawi zina, chopukutira chotchinga chikhoza kukakamiza kuti mayendedwe apakatikati akhale ziro ziro zisanachitike (ndikusinthanso kwapano) mumayendedwe apano.Ngati kusokoneza nthawi yogwiritsira ntchito sikuli bwino pokhudzana ndi mawonekedwe a AC-voltage waveform (pamene arc yazimitsidwa koma ma arc akuyendabe ndipo ionization isanawonongeke mu interrupter), voteji ikhoza kupitirira malire a kupirira magetsi. kuyatsa arc, kuchititsa mwadzidzidzi mafunde osakhalitsa.Mulimonse momwe zingakhalire, oscillation imalowetsedwa mu dongosolo lomwe lingapangitse kuti mphamvu yamagetsi ipitirire.Opanga ma vacuum-interrupter amathana ndi nkhawazi posankha zida zolumikizirana ndi mapangidwe kuti achepetse kudula komwe kulipo.Kuteteza zida kumagetsi opitilira muyeso, zida zosinthira vacuum nthawi zambiri zimakhala ndi zomangira ma surge.
