Isiphazamisi seVacuum yeMV VCB(iqokobhe leceramic, Umbane olinganisiweyo: 7.2kV-12kV)

Isiphazamisi sevacuum ngokubanzi sinonxibelelwano olunye oluzinzileyo kunye nolunye olushukumayo, imivumbo evumayo ukuvumela intshukumo yolo qhagamshelwano, kunye nezikhuselo ze-arc ezivalwe ngeglasi etywiniweyo, i-ceramic okanye indlu yentsimbi enevacuum ephezulu.Umnxeba ohambayo uxhunywe nge-braid eguquguqukayo kwisiphaluka sangaphandle, kwaye ushukunyiswa ngumatshini xa kufuneka isixhobo ukuba sivule okanye sivale.Ekubeni uxinzelelo lomoya luthanda ukuvala abafowunelwa, indlela yokusebenza kufuneka ibambe abafowunelwa bavule ngokuchasene namandla okuvala omoya kwimivumbo.
Indawo evalekileyo yesiphazamisi yenziwe ngeglasi okanye ngeceramic.Iimpawu zeHermetic ziqinisekisa ukuba i-vacuum yokuphazamiseka igcinwa ubomi besixhobo.Indawo ebiyelweyo mayingangeni kwirhasi, kwaye mayingakhuphi igesi evalelekileyo.I-stainless-steel bellows ihlukanisa i-vacuum ngaphakathi kwesiphazamisi ukusuka kwi-atmosphere yangaphandle kwaye ihambisa umnxibelelwano phakathi koluhlu oluchaziweyo, ukuvula nokuvala iswitshi.
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.
Ubuninzi bomphunga buxhomekeke kumbane kwi-arcing.Ngenxa yokuhla kwemowudi yamaza angoku isantya sokuphuma komphunga kwaye emva koziro wangoku, indawo ephakathi iphinda ifumane amandla ayo edielectric ebonelelwe ngoxinzelelo lomphunga olujikeleze unxibelelwano oluncitshisiweyo.Ngenxa yoko, i-arc ayiphindi inqande kwakhona ngenxa yokuba umphunga wesinyithi ukhutshwa ngokukhawuleza kwindawo yoqhagamshelwano.
