17.5kV Ring Main Unit (doko loyesa chingwe chakunja)

SF6 insulating medium

SF6 ndiyabwino kwambiri pakutchinjiriza ndi kuzimitsa kwa arc chifukwa cha mphamvu yake yotenthetsera kutentha kwambiri, yomwe imatha kufalitsa mwachangu kutentha pakuyatsa kwa arc, matenthedwe apamwamba kwambiri paziro pakali pano, zomwe zingapangitse kuti arc azizizira komanso mawonekedwe ena apamwamba.
Kusindikiza kwabwino
Tanki ya gasi imapangidwa ndi chitsulo chosapanga dzimbiri cha 2mm chopangidwa ndi chitsulo chosapanga dzimbiri, ndipo tsinde lachitsulo chosapanga dzimbiri limatengera mawonekedwe apadera osindikizira, omwe amatsimikizira kuti thanki yamafuta imakhala ndi mpweya wabwino kwambiri. SF6 gasi ndi ≤0.01%.Onetsetsani kuti moyo wa zida ndi zaka 30.
Zopanda pake komanso zosakonza
Chogulitsacho chimatengera mapangidwe amtundu, mawonekedwe ophatikizika, chopondapo chaching'ono, kukhazikitsa kosavuta komanso kopanda kukonza.
Automation interfaces
Kusintha kwa unit motor-drive kumasungidwa mawonekedwe a automation network yogawa, ndipo kulumikizana ndi RTU ndikosavuta komanso kosavuta.Udindo woyika RTU umasungidwa mu nduna.
Njira Zapamwamba
Gasi thanki kupanga mwatsatanetsatane, kugwiritsa ntchito laser kudula ndi CNC kukhomerera, kuchepetsa, pindani ndi zipangizo zina kuonetsetsa kuti kulondola dimensional wa gawo thanki mpweya processing, kugwiritsa ntchito maloboti kuwotcherera, basi kuwotcherera njira kuonetsetsa mkulu kuwotcherera dzuwa, khalidwe khola. wa thanki gasi, weld msoko wokongola, kuteteza mpweya kutayikira mu thanki gasi ndi kuwukira chinyezi kuchokera kunja, kukulitsa chitetezo SSU mndandanda wa makabati inflatable, ntchito bata nduna.
Njira yolumikizira mabasi
Chophimba chamkati chamkati chimayikidwa pambali pa kabati ya switchgear, pogwiritsa ntchito mphira wa silikoni ngati zotchingira, ndipo amagwiritsidwa ntchito kuzindikira kugwiritsa ntchito mtundu womwewo wa mphete yayikulu yokhala ndi mayunitsi osiyanasiyana wamba kapena chipinda chimodzi cha gasi kudzera pa cholumikizira cha basi. kuyika pamodzi kabati.
Zipangizo zosaphulika
Tanki iliyonse imakhala ndi nembanemba yotsimikizira kuphulika yomwe ili pamwamba pa 0.2MPa kuti ichepetse kupanikizika pakagwa vuto.Nembanemba yosayaka moto imatha kuyikidwa pansi kapena pamwamba pa thanki.
Kusintha kwa malo atatu
Mapangidwe atatu amatengedwa kuti atseke, kutsegula ndi kuyika malo osinthira katundu, omwe ndi otetezeka komanso odalirika.Gridi yozimitsa ya arc + yozungulira ya arc imakhala ndi zotchingira bwino komanso zosweka.
Load switch makina
Single spring double operation shafts design, yomangidwa modalirika kutseka, kutsegula, kukhazikitsa malire otsekera chipangizo, onetsetsani kuti kutseka ndi kutsegula sikungawonekere mowonekera.Moyo wamakina wa mankhwalawa ndi nthawi zopitilira 10000, ndipo zida zamagetsi zimapangidwira kale, zomwe zitha kukhazikitsidwa ndikusungidwa nthawi iliyonse.
