Isiphazamisi sevacuum yokutshintsha umthwalo wekhefu (203)

Indlela yokusebenza yangaphandle iqhuba umnxibelelwano ohambayo, ovula kwaye uvale isiphaluka esixhunyiwe.Isiphazamisi sevacuum sibandakanya umkhono wesikhokelo ukulawula unxibelelwano oluhambayo kunye nokukhusela imivumbo yokutywina ekujikeni, okuya kuthi bufutshane kakhulu ubomi bayo.
Nangona ezinye iidizayini zesiphazamisi sevacuum zinonxibelelwano olulula lwempundu, abafowunelwa ngokuqhelekileyo bakhiwe ngeeslots, iinduli, okanye iigrooves ukuphucula amandla abo okuphula imisinga ephezulu.I-arc yangoku equkuqelayo kunxibelelwano olumile ivelisa amandla amagnetic kwikholamu ye-arc, ebangela ukuba indawo yoqhagamshelwano ye-arc ihambe ngokukhawuleza kumphezulu woqhagamshelwano.Oku kunciphisa ukudibanisa ukugqoka ngenxa yokukhukuliseka kwe-arc, enyibilikisa isinyithi soqhagamshelwano kwindawo yokudibanisa.
Kwizikhewu zesekethe, izixhobo zokunxibelelana ne-vacuum-interrupter ngokuyintloko ziyi-50-50 ye-copper-chromium alloy.Zisenokwenziwa ngokuwelda icwecwe le-copper-chrome alloy kwindawo ephezulu kunye nesezantsi yokudibanisa phezu kwesihlalo soqhagamshelwano esenziwe ngobhedu olungenayo i-oksijini.Ezinye izinto, ezifana nesilivere, i-tungsten kunye neekhompawundi ze-tungsten, zisetyenziswa kwezinye iziphazamisi zoyilo.Isakhiwo soqhagamshelwano lwesiphazamisi se-vacuum sinempembelelo enkulu ekuqhekezeni kwayo, ukuqina kombane kunye nenqanaba lokunqunyulwa kwangoku.
Xa uqhawula umlinganiselo othile wangoku, ngexesha lokwahlulwa koqhagamshelwano oluguquguqukayo kunye noluzinzileyo, lwangoku luyancipha ukuya kwindawo apho abafowunelwa bahlukana nje, okukhokelela ekunyukeni okubukhali kokuchasana phakathi kwee-electrodes kunye nokunyuka ngokukhawuleza kweqondo lokushisa, de Ukukhutshwa kwesinyithi se-electrode evaporation kwenzeka, kwaye kwangaxeshanye, ukuqina kombane okuphezulu kakhulu kuyenziwa, okukhokelela ekuphumeni okunamandla kakhulu kunye nokuqhekeka kwe-gap, okukhokelela kwi-vacuum arc.Xa i-voltage ye-frequency yamandla isondele kwi-zero, kwaye kwangaxeshanye, ngenxa yokunyuka komgama wokuvula uqhagamshelwano, iplasma ye-arc vacuum isasazeka ngokukhawuleza.Emva kokuba i-arc yangoku idlula i-zero, i-medium kwi-gap yoqhagamshelwano itshintsha ngokukhawuleza ukusuka kumqhubi ukuya kwi-insulator, ngoko ke i-current iyanqunyulwa.Ngenxa yesakhiwo esikhethekileyo soqhagamshelwano, i-gap yoqhagamshelwano iya kuvelisa intsimi yamagnetic longitudinal ngexesha le-arcing.Le ntsimi yamagnetic inokwenza i-arc isasazwe ngokulinganayo kwindawo yoqhagamshelwano, igcine i-arc voltage ephantsi, kwaye yenza igumbi lokucima i-arc ye-vacuum ibe nesantya esiphezulu sokubuyisela amandla e-arc dielectric, okukhokelela kumandla amancinci e-arc kunye nesantya esincinci sokubola.
