Ixesha lokukhutshwa : May-11-2022
1.Amagqabantshintshiyetshintsha umthwalo
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.
2.Imisebenzi esisiseko kunye neempawuyetshintsha umthwalo
2.1. Iswitshi yebreaker yomthwalo ilungelelanisa ukwaphuka kabini, ulwakhiwo loqhagamshelwano olujikelezayo, olunezi ntlobo zintathu zilandelayo zamazwe asebenzayo: Ukuvala,ukuvulwa,umhlaba.
2.2. Ukusebenzisa igesi ye-SF6 njenge-arc yokucima kunye ne-insulating medium, i-circuit engundoqo itywina ngezindlu eziphezulu kunye nezisezantsi ezigalela i-epoxy resin, umsebenzi we-conductive awuchatshazelwa yimpembelelo yangaphandle.
2.3.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.
2.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.
2.5.Ubungakanani obuncinci, ubunzima obulula, ukugcinwa kwe-free, kulula kwaye kukhuselekile ukusebenza.
3.Ulungelelwaniso oluchanekileyo lwetshintsha umthwalokunye nefuse
3.1 Umahluko osisiseko phakathi kokutshintsha komthwalo kunye ne-fuse kukuba i-fuse inamandla okuqhawula i-short-circuit current, ngelixa ukutshintshwa komthwalo kusebenza kuphela njengokutshintsha komthwalo wangoku.Ngokuqhelekileyo kukholelwa ukuba umtshini womthwalo uvala kwaye uhlukanise umjelo osebenzayo, kwaye i-fuse ivula i-short-circuit current.Nangona kunjalo, xa iphoso lenzeka, ngenxa yokuba inqanaba lesithathu langoku alifani ngokufanayo kunye nephutha le-fuses, umehluko wexesha le-fuse phakathi kwee-fuses zesigaba sesithathu awunakuphepheka.Emva kokuba i-prime minister isuse iphoso, ukuba ukutshintshwa komthwalo akukwazi ukuphula umthwalo wangoku ngexesha, kuya kubangela ukuhanjiswa kwangoku kunye nokusebenza kwesigaba sesibini, kubangela umonakalo kwisixhobo esinamandla.I-fuse enomhlaseli, edibene nokutshintsha komthwalo kunye nesixhobo sokuhamba, inokusombulula ingxaki yokungabikho komsebenzi wesigaba.Xa i-fuse ye-fuse inyibilika, ifowuni yokutshintsha umthwalo inqanyulwe ngokukhawuleza phantsi kokusebenza komhlaseli.Abavelisi ubukhulu becala basebenzisa unxibelelwano lweebha ezine.Xa ukutshintshwa komthwalo kuvaliwe, imithombo yokuvala kunye nokuvula igcina amandla ngexesha elifanayo.Xa i-bar-bar linkage idlula indawo efileyo, amandla entwasahlobo yokuvala akhululwa, kwaye utshintsho luvaliwe.Amandla e-brake spring asagcinwe yi-half-shaft mechanism.Emva kokuba umhlaseli ebetha, i-half-shaft iyachithwa, amandla omthombo wokuvula akhululwa, kwaye utshintsho lusebenza.Ke ngoko, iifuse kunye nabahlaseli kunye nokutshintsha komthwalo kunye nezixhobo zokukhwela oomatshini kufuneka zikhethwe zisetyenziswe.
3.2 Kufuneka icaciswe into yokuba iifuse ezisetyenziswayo zisetyenziswa ikakhulu njenge-backup protection fuses.Le fuse inomlinganiselo omncinci wokuqhawula, okuyi-2.5 ukuya ku-3 amaxesha alinganisiweyo akhoyo e-fuse.Xa ingaphantsi kokwaphuka kwangoku, i-fuse yogcino ayinako Ukuqhawula lo mjelo, nto leyo eyahlulayo kuluhlu olupheleleyo lwe-fuse.Uluhlu olupheleleyo lwe-fuse lunokwaphula ngokuthembekileyo nawuphi na umsinga phakathi kokunyibilika kwenyibilika kunye nokwaphuka okureyithiweyo (40kA), kodwa kuyabiza.Xa i-foult current ingaphantsi kobuncinci bokuphulwa kwe-fuse ye-backup, nangona i-fuse ingenakuqinisekisa ukuphulwa kwayo, i-fuse iya kubethwa, i- impactor kwimemori yayo iya kubetha, kwaye ukutshintshwa komthwalo wempembelelo kuya kwaphulwa.Ngokomzekelo, i-fuse ene-current rated current ye-100A inomlinganiselo omncinci wokuqhawula malunga ne-250-300A.Kulo mmandla wangoku, i-fuse ayikwazi ukuphulwa, kodwa i-fuse ivuthela i-striker, kunye nohambo lokutshintsha umthwalo wempembelelo, ukuphula le yangoku, njengokuba Ukuba ukutshintshwa komthwalo we-600A kukhethiwe, kunokuphazamiseka ngokuthembekileyo.
