Imveliso ineempawu zesakhiwo esilula, ukusebenza okuguquguqukayo, ukudibanisa okuthembekileyo, ukufakela okufanelekileyo, njl njl. Inokubonelela ngezisombululo zobugcisa ezanelisayo kwizihlandlo ezahlukeneyo zezicelo kunye nabasebenzisi abahlukeneyo. Ukwamkelwa kobuchwephesha bokuva kunye nobuchwepheshe bolwazi, kunye nokusebenza kobugcisa kunye nezikimu ezilula neziguquguqukayo zoqwalaselo, zinokuhlangabezana neemfuno ezihlala zitshintsha zentengiso kwaye zilungele iimfuno zobukrelekrele begridi.
I-GHXH-12 yokusingqongileyo igesi efakwe i-insulated ring unit unit ilungele i-industry kunye ne-civil cable ring network kunye neeprojekthi ze-terminal network. Njengoko ukwamkelwa kunye nokuhanjiswa kwamandla ombane, kukulungele ngokukodwa ukuhanjiswa kwamandla kwiindawo zokuhlala ezidolophini, izitishi ezincinci zesekondari, izikhululo zokuvula kunye nokuvala, iibhokisi zesebe lentambo, iibhokisi zebhokisi, amashishini amashishini kunye nemigodi, iindawo zokuthenga, izikhululo zeenqwelo moya, i-subways. , ukuveliswa kwamandla omoya, amabala emidlalo, oololiwe, iitonela kunye nezinye iindawo ezisetyenziswayo.
I-GHXH-12 yokhuseleko lokusingqongileyo i-gas-insulated ring unit main unit series idibana nemigangatho yesizwe efanelekileyo, imigangatho yoshishino lwamandla kunye neminye imigangatho. Ukutshintsha kwayo kunye nezixhobo eziphambili zombane ziimodyuli ezidibeneyo, iimodyuli eziqhubayo phakathi kwezigaba ziiphakheji zokugquma eziqinileyo, i-wiring yangaphandle ithatha i-cable joints shielded cable, kwaye ibhasi yokudibanisa iyunithi ithatha iibhasi ezikhuselweyo ezikhuselweyo. Ngoko ke, ukhuseleko lokusetyenziswa luphuculwe kakhulu, indlela yokusebenza ithatha indlela yasentwasahlobo, kwaye ubomi bomatshini bungaphezu kwamaxesha angama-10,000. Idatha yokusebenza kwayo kunye nemeko yezixhobo inokujongwa kwaye ibekwe esweni ukude, kwaye ayinakuhoywa. Sisixhobo sokuhambisa amandla kunye nohlobo lomsebenzi.
Ezi yunithi zilandelayo zinokukhethwa kwikhabhinethi ukwenza iyunithi yobonelelo lwamandla eyongayo nesebenzayo:
1. Iyunithi ye-vacuum ye-circuit breaker (630A, 20-25kA)
2. Iyunithi yokutshintsha umthwalo wevacuum (630A, 20-25kA)
Iimpawu zeMveliso
1. Ukhuseleko lokusingqongileyo
Zonke izinto ezisetyenziselwa ukuveliswa kwemveliso azinabungozi kwaye azinabungozi. I-N2 okanye umoya owomileyo usetyenziswa njengendlela yokukhusela ukunciphisa ukukhutshwa kwegesi ye-greenhouse kunye nokufezekisa iinjongo zokukhusela indalo. Akukho zinto ezinobuthi neziyingozi ezikhutshwayo ngexesha lokusetyenziswa. Inokuphinda isetyenziswe kwaye iphinde isetyenziswe, echaza ukukhuselwa kokusingqongileyo kokusetyenziswa.
2. Uluhlu olubanzi lwesicelo
Musa ukusebenzisa nayiphi na igesi enetyhefu kunye neyingozi, emisela ukhuseleko lwendawo yokusetyenziswa. Nokuba kumagumbi angaphantsi, kwiitonela, kwiinqanawa, nakwiindawo ezahlukeneyo ngaphakathi nangaphandle. Ingaphakathi legumbi elinoxinzelelo oluphezulu linokuzaliswa ngomoya owomileyo okanye i-nitrogen, efanelekileyo kwiimeko ezinzima ezifana: ukuphakama okuphezulu, umoya onamandla kunye nesanti, ukushisa okuphantsi, ukubanda okukhulu, iimfuno eziphakamileyo zokusingqongileyo, iindawo zokusebenza rhoqo, ukhuseleko. iindawo ezinokuthi zingaqhushumba, inkungu yetyuwa eninzi, kunye nokusetyenziswa ngokukhuselekileyo phantsi kweemeko zokujiya . Ifakwe ngokupheleleyo kwaye ifakwe ngokupheleleyo, ifanelekile ukuba izixhobo ziqhubeke nokusebenza emva kokuthatha amanyathelo okucoca kunye nokomisa emva kwexesha elifutshane lokungena kwamanzi.
3. Isondlo sasimahla
Ukongeza kwindlela yokusebenza, i-GHXH-12 ye-GHXH-12 yokukhusela i-gas-insulated ring unit unit series ikwimeko etywinwe ngokupheleleyo, inxalenye yokutshintsha i-high-voltage ivalwe ngokupheleleyo, ukwenzela ukuba ukucoca kunye nokugcinwa kugwenywe, kunye neendleko ukusebenza kunye nokugcinwa kungancitshiswa.
Iqondo lokuzenzekelayo kwe-switchgear liphezulu kakhulu, kwaye umsebenzi wokukhangela kwi-intanethi uya kwazisa umsebenzisi ngokusebenza kwesixhobo ngexesha langempela, elilungele ngakumbi ukuzenzekelayo kwinethiwekhi yokusabalalisa, ukunciphisa iindleko zokusebenza, kunye nokunciphisa iindleko zemveliso yeenkampani zamandla.
4. Ukhuseleko oluphezulu
Inkqubo edibeneyo yokudibanisa kunye nokudibanisa, umgama wokuhlukanisa isigaba sesithathu ubonakala ngokucacileyo, ukuphepha ukwenzeka kweengozi ze-misoperation. Ukusetyenziswa kwegesi ye-SF6 kucinywa, kwaye isakhiwo sokuhlukanisa i-interphase siqiniswa ukuphepha ukwanda okanye ukuqhuma kwengozi yokuqhuma okubangelwa isiphaluka esifutshane phakathi kwezigaba okanye iisekethe ezininzi. Isiphazamisi se-vacuum esine-vacuum yamandla ekhabhinethi yegesi yokukhusela indalo esisingqongileyo iyamkelwa, kwaye isibonda esitywiniweyo sinomsebenzi wokukhusela ngakumbi wokutshintsha.
5. Kulula ukusebenza
Ukuqhawula kunye nokutshintsha komhlaba ngesiphatho esinye kuphela sokusebenza, kwaye akukho mfuneko yokuchonga kwaye ukhathazeke ngeempazamo. Xa i-breaker yesiphaluka isebenza, i-handle yokusebenza ye-disconnectorand switch switch ayikwazi ukusebenza, kwaye uqeqesho olunzima lobugcisa alufunwa, okwenza umsebenzi ube lula kakhulu, ukuphepha iimpazamo zokusebenza.
