Isishwankathelo
Uhlobo lwe-FLN lwangaphakathi lwangaphakathi lombane ophezulu we-AC iswitshi yesiqhekeza somthwalo sibhekisa kwitekhnoloji entsha yamazwe ngamazwe kunye nokuphuhlisa izixhobo zokutshintsha ngokwemigangatho efanelekileyo kwinkqubo yamandla ombane yaseTshayina.Izalathi zayo zokusebenza ngokuthobela ngokupheleleyo IEC420,694,129 kunye nemigangatho yesizwe GB3804-2004“3.6kV-0.5kV ombane ophezulu AC iswitshi soqhawulo lomthwalo”GB1985-2004“i-high-voltage AC isolation switch kunye ne-earthing switch”,GB/ T11022-1999“ iimfuno zobugcisa zombane ophezulu wesixhobo sokutshintsha kunye nemigangatho yezixhobo zokulawula“, Le yeyona nto iphambili yokutshintsha i-RMU.Isitshixo soqhawulo-mthwalo yingqokelela yezixhobo ezininzi ezisebenza ngamandla ombane ophakathi kumasango, isango elingaphantsi, i-earthing.Kwindawo etywinwe ngokupheleleyo kunye nokomeleza ulwakhiwo lwezindlu ze-epoxy resin ukuze zizaliswe ngegesi ye-SF6, 0.05MPa, kunye namacandelo amancinci okuphumeza le misebenzi mithathu ingentla,ukuqinisekisa umgangatho wemveliso, ukuphucula ukuthembeka, ukugcinwa-free.Inokuqhutywa ngokukhuselekileyo iminyaka engaphezu kwama-20 kwiimeko eziqhelekileyo.
Imisebenzi esisiseko kunye neempawu
I-1.I-switch breaker switch iqhelanisa ukwaphuka kabini, isakhiwo soqhagamshelwano esijikelezayo, kunye neentlobo ezintathu ezilandelayo zeendawo zokusebenza: Ukuvala, ukuvulwa, uMhlaba.
2.Ukusebenzisa i-SF6 igesi njenge-arc yokucima kunye ne-insulating medium, i-circuit engundoqo itywina ngezindlu eziphezulu kunye nezisezantsi ezigalela i-epoxy resin, umsebenzi we-conductive awuthinteki kwiimpembelelo zangaphandle.
3.Ukusebenza kakuhle kokhuseleko.Ukuba i-arcing yangaphakathi iyenzeka, indlu inesakhiwo sangaphakathi esibuthathaka, iya kugxalathelana ukuvula, ilandelwa yikhabhinethi engaphezulu kwe-shutter ukukhululwa kwe-arc ebomvu yomoya evulekileyo yoxinzelelo olujoliswe ngaphandle kwekhabhinethi, qinisekisa ukuba iswitshi.
iitshekhi zokhuseleko kwikhabhinethi.
I-4.I-switch breaker switch ibeka amasango, ukuvula, ukutshintsha umhlaba ezintathu kwelinye, zizaliswe ngegesi ye-SF6 efakwe kwi-epoxy resin yezindlu, i-interlock yeendawo ezintathu, i-compact structure, ukhuseleko oluphezulu kunye nokuthembeka.
5.Ubungakanani obuncinci, ubunzima obulula, ukugcinwa kwe-free, kulula kwaye kukhuselekile ukusebenza.
