Kune yakakwira-voltage vacuum seketi mabreak anogara achiwedzeredzwa, pane zvinotevera zvinhu:
Idzo dzinofanirwa kuvandudzwa pamwedzi mitanhatu yega yega ndeidzi:
1) Tarisa kutaridzika kweiyo nzira yekufambisa yeakakwira-voltage vacuum circuit breaker, chenesa guruva, uye isa girisi; simbisa zvisungo zvakasununguka; tarisa iyo nzira yekufambisa kuti ive nechokwadi chekuvhurwa kwakavimbika uye kuvhara kwedunhu rinotyora; chenesa muparadzi wedunhu, Iite yakachena kuti uve nechokwadi chekushanda kwakachengeteka; shandisa girisi yekuzora kuita kuti michina ichinjike uye kuderedza kukwenya nekupfeka.
2) Tarisa kana simbi yesimbi yekuvhara coil yakanamatira, kana simba rekuvhara rinosangana nezvinodiwa, uye nzvimbo yakafa yekubata (yakakura nzvimbo yakafa ichakonzera kuoma mukuvhura, uye kana iri diki, ichaita. kudonha nyore).
3) Pini yepini: Ingave pini yakaita seshizha yakanyanya kutetepa; ingave pini yakaita sembiru yakagonya kana kuti inogona kudonha.
4) Buffer: Ingave iyo hydraulic buffer iri kubuda mafuta, ine mafuta mashoma kana isiri kushanda; kana chitubu buffer chiri kushanda.
5) Kunyangwe iyo yekugumbura musimboti inogona kufamba yakasununguka.
6) Kana paine zvirema zvinoonekwa muzvikamu zvekudzivirira. Kana paine chero chakakanganisika, shandisa 2500V shake mita kuyedza iyo insulation kuti uone kana kutsiva uye kuita rekodhi.
7) Shandisa bhiriji remaoko maviri kuti uone kupikisa kweDC kwekushandura mushure mekuvhara (haifaniri kunge yakakura kudarika 40Ω), uye ita rekodhi, kana yakakura kudarika Ω, kamuri yekudzima arc inofanira kutsiviwa.
8) Tarisa uone kana iyo arc yekudzima kamuri yakaputsika, uye kana zvikamu zvemukati zviri kuchembera.
9) Tarisa chechipiri chedunhu uye kuyera kudzivirira kwekudzivirira kwechipiri chedunhu.
Idzo dzinoda kugadziriswa pagore ndeidzi:
1) Nguva yekuvhara: DC electromagnetic haisi kupfuura 0.15s, chitubu chekuchengetedza simba hachipfuuri 0.15s; nguva yekuvhura haisi kupfuura 0.06s; iyo synchronism yemazaru matatu ishoma pane kana kuenzana ne2ms;
2) Iyo bounce nguva yekuvhara kusangana ≤5ms;
3) Avhareji yekuvhara kumhanya ndeye 0.55m/s±0.15m/s;
4) Avhareji yekuvhura kumhanya (usati wasangana nemafuta buffer) 1m/s±0.3m/sc
Kuyera iyo yakatemerwa insulation level, kazhinji chete kuyera iyo lmin simba frequency inomira voltage ye42kV, hapana flashover; zvisina magumo, iyo vacuum dhigirii kuyerwa kunogona kusiiwa, asi iyo frequency yemagetsi inomira voltage test pakati pezvikamu uye mafractures inofanira kuitwa, uye 42kV kana kupfuura inodiwa (hapana simba frequency mamiriro Inogona kutsiviwa neDC). Kune vacuum circuit breaker dzave dzichishandiswa kwemakore mashanu kusvika gumi, mugadziri anofanirwa kugadzirisa chinhambwe chekuvhura, kubata sitiroko, mafuta buffer buffer sitiroko, chikamu chepakati chinhambwe, nhatu-nhanho yekuvhura kuwiriranisa, yekuvhara yekubata kudzvanywa, bounce nguva, The cumulative. inotenderwa kupfeka ukobvu hwekufamba uye static contacts, nezvimwe.
