Njira yokonza ya high voltage vacuum circuit breaker

Kwa ma voltage vacuum circuit breakers omwe amasinthidwa pafupipafupi, pali zinthu izi:
Zomwe zimayenera kusinthidwa pamiyezi isanu ndi umodzi iliyonse ndi:
1) Yang'anani mawonekedwe a njira yotumizira yamagetsi othamanga kwambiri, yeretsani fumbi, ndikuthira mafuta; kumangitsa zomangira zotayirira; yang'anani njira yotumizira kuti muwonetsetse kutsegula ndi kutseka kodalirika kwa wowononga dera; yeretsani chophwanyira dera, Lipange kukhala loyera kuti muwonetsetse kuti likugwira ntchito bwino; gwiritsani ntchito mafuta odzola kuti makinawo azitha kusintha ndikuchepetsa kukangana ndi kuvala.
2) Yang'anani ngati chitsulo chachitsulo cha koyilo yotseka chatsekedwa, ngati mphamvu yotseka ikukwaniritsa zofunikira, ndi malo akufa a nsomba (malo aakulu kwambiri omwe amafa amachititsa kuti azitsegula, ndipo ngati ali ochepa kwambiri, amatha kugwa mosavuta).
3) Pini: Kaya pini yooneka ngati pepala ndiyoonda kwambiri; kaya pini yooneka ngati mzati ndi yopindika kapena ingagwe.
4) Buffer: Kaya hydraulic buffer ikutha mafuta, imakhala ndi mafuta ochepa kapena yatha; kaya buffer ya masika ikugwira ntchito.
5) Kaya pachimake chikhoza kuyenda momasuka.
6) Kaya pali zolakwika zowoneka m'zigawo zotsekera. Ngati pali cholakwika chilichonse, gwiritsani ntchito shake mita ya 2500V kuyesa kutsekereza kuti muwone ngati mungasinthe ndikulemba mbiri.
7) Gwiritsani ntchito mlatho wa mikono iwiri kuti muyese kukana kwa DC kwa chosinthira pambuyo pa kutseka (sikuyenera kukhala wamkulu kuposa 40Ω), ndikupanga mbiri, ngati ili yaikulu kuposa Ω, chipinda chozimitsa arc chiyenera kusinthidwa.
8) Onani ngati chipinda chozimitsira arc chasweka, komanso ngati ziwalo zamkati zikukalamba.
9) Yang'anani dera lachiwiri ndikuyesa kukana kwachitetezo cha dera lachiwiri.

Zomwe ziyenera kusinthidwa pachaka ndi:
1) Kutseka nthawi: DC electromagnetic sikuposa 0.15s, kusungirako mphamvu yamasika sikuposa 0.15s; nthawi yotsegulira sikuposa 0.06s; synchronism ya mipata itatu ndi yocheperapo kapena yofanana ndi 2ms;
2) Nthawi yopumira yolumikizana ndi kutseka ≤5ms;
3) Pafupifupi kutseka liwiro ndi 0.55m/s±0.15m/s;
4) Avereji yotsegula liwiro (musanakumane ndi chotchinga mafuta) 1m/s±0.3m/sc
Kuyeza mulingo kutchinjiriza oveteredwa, zambiri kokha kuyeza lmin mphamvu pafupipafupi kupirira voteji 42kV, palibe flashover; mopanda malire, muyeso wa digiri ya vacuum ukhoza kusiyidwa, koma ma frequency amphamvu opirira kuyesedwa kwamagetsi pakati pa magawo ndi ma fractures ayenera kuchitidwa, ndipo 42kV kapena kupitilira apo ndikofunikira (palibe ma frequency amagetsi omwe angasinthidwe ndi DC). Kwa owononga magetsi omwe akhala akugwiritsidwa ntchito kwa zaka 5-10, wopanga akuyenera kusintha mtunda wotsegulira, kugundana, kugunda kwamafuta, mtunda wapakati, mtunda wapakati, kulumikizana kwa magawo atatu, kutsekeka kolumikizana, nthawi yopumira, Kuchulukitsa. makulidwe ovomerezeka ovala oyenda komanso osasunthika, etc.
