I-HRW/HRXWO 10-35KV 10A Uhlobo oluxhathisa ungcoliseko lwangaphandle uhlobo lwesilicon irabha yamandla ombane aphezulu okunciphisa ifuse yangoku
Ingcaciso yeMveliso
I-fuse yangoku yokunciphisa amandla ombane aphezulu iyasebenza kwi-AC 50Hz yangaphakathi, amandla ombane alinganisiweyo yi-3.6KV, 7.2KV, 12KV, 24KV, 40.5KV, imisinga ereyithiweyo ye-0.5 kunye ne-2, 3, 5, 7.5, 10A, kwaye iyasebenza ekukhuseleni iinkqubo ukulayisha ngaphezulu kunye neempazamo zesekethe emfutshane ye-35KV yangaphandle yoguqulo lombane kunye neentambo zamandla.Ingasetyenziswa kunye nezinye izixhobo zokutshintsha, ezinjengokutshintsha komthwalo kunye nabafowunelwa bokwenene, njengento yokukhusela isiphaluka esifutshane kunye nokugqithiswa kwamandla aguquguqukayo kunye nezinye izixhobo ezixhasayo, kwaye iyimfuneko imveliso exhasayo kwizakhelo zokutshintsha eziphezulu ze-voltage, ring izakhelo zothungelwano, kunye nezikhululo zombane ezisezantsi/ezisezantsi.
I-fuse yokunciphisa amandla ombane aphezulu inomda wangoku kunye nokukhawuleza.Incopho yexabiso le-fault current idla ngokubonakala isiqingatha samaza.Xa umzimba webhulorho unqanyuliwe, yonke i-current circuit current iya kudluliselwa kwi-high-voltage current limiting fuse.Umjelo wesiphaluka omfutshane wangaphakathi we-fuse uya kuba ngumphunga, udilize, uvelise i-arc phakathi kwezithuba kwaye ucime i-arc kwixesha elizayo kwaye xa uphakama, unciphise kwaye unqumle ngenkani i-short circuit current (t ＜ 2ms), ukwenzela ukuba umbane awukwazi. ukufikelela kwixabiso elilindelekileyo lencopho yombane wesiphaluka esifutshane.Xa i-short-circuit current iphakama kwi-Ip, i-fuse iya kuxubha kwaye inqumle okwangoku.I-Ip ye-cut-off yangoku kuphela malunga ne-15% yexabiso eliphezulu lexabiso elilindelekileyo langoku, linciphisa kakhulu impembelelo yesiphoso sangoku kumandla we-electrodynamic kunye nefuthe le-thermal yokuvelisa amandla kunye nezixhobo zenguqu.Amandla ombane we-arc aveliswa yi-fuse ye-high-voltage yangoku yokunciphisa i-fuse inokuthintelwa kukunganyangeki kwe-nonlinear, enokuthi isebenzisane nokumelana nebhulorho ukusombulula ingxaki yokungonelanga komthamo we-voltage yangoku yokunciphisa i-fuse kunye nokuphucula uluhlu lwesicelo sayo yonke. isixhobo.
I-fuse yenziwe ityhubhu enyibilikayo, i-porcelain bushing (i-silicone rubber insulation sheath), i-fastening flange, i-transverse post insulator kunye ne-terminal.Lungisa i-terminal caps kunye neepayipi ezinyibilikayo kuzo zombini iziphelo kwi-porcelain bushing ngokucinezela, uze ulungise i-porcelain bushing kwi-rod post insulator nge-flange eqinile.
Umbhobho onyibilikayo uthatha unonophelo nge-silicon oxide ephezulu njenge-arc yokucima umlilo, kunye nocingo lwetsimbi olunobubanzi obuncinci lusetyenziswa njenge-fuse.Xa i-overload yangoku okanye i-short circuit current idlula kwi-tube yokunyibilika, i-fuse iya kunyibilika ngokukhawuleza.I-arc yenzeka kwiislits ezininzi ezixineneyo ezihambelanayo.Umphunga wensimbi kwi-arc ungena kwintlabathi ye-quartz, unqanyulwe ngamandla, kwaye ucima ngokukhawuleza i-arc.Ke ngoko, i-fuse inokusebenza kakuhle kunye nomthamo omkhulu wokuphuka.
Inkcazo yoMfanekiso
Iiparamitha zobugcisa
Iimpawu zemveliso
1. Umthamo ophezulu wokuqhawula.Ngokubanzi, umlinganiselo wokwaphulwa kwesekethe emfutshane (ixabiso elisebenzayo elilindelekileyo) le fuse zasekhaya ezinevoltage eziphezulu zomda yi-50kA, kunye nomthamo wokwaphulwa kwesekethe emfutshane kwezinye iimveliso ezivela kumazwe angaphandle afikelela kuma-63kA.
2. Umthamo wangoku wokunciphisa amandla, ngokubanzi i-fuses yasekhaya ene-high-voltage current-miniting fuses, efana ne-100A fuses, ixabiso lencopho yangoku elisikiweyo limalunga ne-18kA xa ixabiso elisebenzayo le-short-circuit current elindelekileyo yi-50kA, ngelixa elithile. I-fuse ye-100A ethathwe kumazwe angaphandle, kwi-Xa ixabiso elisebenzayo le-short-circuit yangoku liyi-63kA, ixabiso elisikiweyo lencopho yangoku yi-18kA kuphela.
3. Kukho ubuncinci bokuqhawula okwangoku.Kwii-fuses ezinqamlekileyo zangoku zokukhusela i-transformer, ubuncinci bexesha lokuqhawula ngokuqhelekileyo buyi-3 ukuya kumaxesha angama-5 ukulinganisa okwangoku kwe-fuse.Xa ukhetha, kufuneka kuqinisekiswe ukuba ubuncinci be-fusing current abukho bukhulu kunobuncinci be-short-circuit current ye-circuit ekhuselweyo.
4. Ukulahlekelwa kwamandla kuncinci, okuqinisekisa ukuba umkhiqizo unokunyuka kweqondo lokushisa eliphantsi.Olu phawu luluncedo ngakumbi xa ifuse isetyenziswa kwisixhobo sokugquma esivalekile ngokupheleleyo.I-voltage ye-arc ephantsi: Ngexesha lenkqubo yokuqhawula, i-arc yombane iphantsi, kwaye xa isetyenziswe kwinkqubo ene-voltage ephantsi kunomlinganiselo olinganisiweyo, i-arc voltage iya kuncitshiswa ngakumbi, ukuze i-12KV fuse isetyenziswe kwi-voltage. I-12KV okanye i-7.2KV inkqubo ngaphandle kokonakalisa ubungozi bokufakelwa kwenkqubo.
5. Iphutha le-curve yeempawu lincinci, kwaye impazamo ye-current character curve ingaphantsi kwe-± 10%, eqinisekisa ukuthembeka kwemveliso.Ngaphezu koko, zonke zithobela umgangatho we-International Electrotechnical Commission (IEC).Uhlobo lwebhasi lunokuthi lufakwe ngokuthe ngqo kwi-busbar kunye nezikrini, ezineenzuzo zomthamo omncinci wofakelo kunye noqhagamshelwano oluthembekileyo;ngelixa i-plug-in uhlobo ilula ukuyibuyisela kwaye inokuqhutywa ngombane.
