Ingcaciso yeMveliso

I-RW12F i-fuses yokuyeka uchungechunge zizixhobo zokukhusela zangaphandle eziphezulu ze-voltage kukuhanjiswa kwamandla kunye neenkqubo zokusasazwa.Zifakwe kwicala eliphezulu le-voltage ye-transformers yokusabalalisa okanye kwimigca yesebe yemigca yokusabalalisa, kwaye isetyenziselwa ukhuseleko olufutshane lwesiphaluka kunye nomthwalo ogqithisiweyo we-transformers kunye nemigca, kunye nokwahlula kunye nokudibanisa imisinga yomthwalo.I-fuse ye-ceramic drop-out ye-voltage ephezulu yenziwe i-ceramic insulating bracket kunye ne-fuse tube.Uqhagamshelwano olusisigxina lufakwe kuzo zombini iziphelo ze-insulating bracket, kwaye uqhagamshelwano oluhambayo lufakwe kuzo zombini iziphelo zetyhubhu ye-fuse.Umbhobho we-fuse uqulunqwe ityhubhu ye-arc yangaphakathi kunye netyhubhu ye-fuse.Umaleko wangaphandle wenziwa ityhubhu yephepha lephenolic okanye ityhubhu yelaphu yeglasi epoxy.I-fuse yohlobo lokulahla umthwalo iphucula i-elastic axiliary contact kunye ne-arc yokucima isigqubuthelo sokwahlula kunye nokudibanisa umthwalo wangoku.

Iimpawu zeZakhiwo zeMveliso kunye nobungakanani bokusetyenziswa

Isakhiwo setyhubhu enyibilikayo:
I-Fuse take yenziwe nge-flberglsaa, i-fum-proof & corrosion-proof.
Isiseko se-Fuse:
Isiseko semveliso sifakwe kwisakhiwo soomatshini kunye ne-insulator.Faka intonga yentsimbi usebenzisa izixhobo ezikhethekileyo zokubopha kunye ne-insulator kunye, unokuma umbane omfutshane wokuvula amandla ombane.
I-fuse engenamanzi ayinamadyunguza, i-deformation, evulekileyo, umthamo omkhulu, i-UV, ubomi obude, iipropathi zombane eziphezulu, amandla e-dielectric kunye nokuqina koomatshini kunye nokukwazi ukuzinikezela.
Umbutho wonke ukuba ungathathi hlangothi, ufakelo olufanelekileyo, olukhuselekileyo noluthembekileyo.
1. Ubushushu be-ambient ayikho ngaphezulu kwe +40 C, hayi ngaphantsi kwe-40 C
2. Umphakamo awudluli kwi-3000m
3.Esona santya somoya siphezulu asidluli kwi-35m/s
4. Ubukhulu benyikima abukho ngaphezu kwe-8 degrees

Ukufakwa kweFuse kunye nokusebenza

1. Ufakelo lwefuse yokulahla:
(1) Ukunyibilika kufuneka kuqiniswe ngexesha lofakelo (ukuze inyibilike ixhomekeke kumandla obunzima malunga ne-24.5N), ngaphandle koko kulula ukubangela ukuba umnxibelelwano ugqithise.
(2) I-fuse efakwe kwingalo yomnqamlezo (ifreyimu) kufuneka iqine kwaye ithembeke, kwaye akufanele kubekho ukugubha okanye ukugubha.
(3) Umbhobho wokunyibilika kufuneka ube ne-angle yokuthotywa kwe-25 ° ± 2 °, ukwenzela ukuba ityhubhu yokunyibilika ikwazi ukuwa ngokukhawuleza ngobunzima bayo xa inyibilika ivuthelwa.
(4) I-fuse kufuneka ifakwe kwingalo yomnqamlezo (isakhelo) kunye nomgama othe nkqo ongekho ngaphantsi kwe-4m ukusuka emhlabeni.Ukuba ifakwe ngaphezu kwe-transformer yokusabalalisa, kufuneka igcine umgama othe tye ongaphezulu kwe-0.5m ukusuka kumda we-contour yangaphandle ye-transformer yokusabalalisa.Ukuwa kombhobho onyibilikayo kubangele ezinye iingozi.
(5) Ubude bombhobho wefuse kufuneka bulungelelaniswe ngokulinganayo.Kuyafuneka ukuba ulwimi lwedada lukwazi ukubamba ngaphezulu kwesibini kwisithathu sobude bonxibelelwano emva kokuvala, ukuze kuthintelwe ukungasebenzi kakuhle kokuziwisa ngexesha lokusebenza, kwaye ityhubhu yefuse ayifanele ibethe i-duckbill., ukwenzela ukuthintela ityhubhu enyibilikayo ukuba ingawi ngexesha emva kokuba i-melted ivuthelwe.
(6) Ukunyibilika okusetyenzisiweyo kufuneka kube yimveliso eqhelekileyo yomenzi oqhelekileyo, kwaye ibe namandla athile omatshini.Ngokubanzi, ukunyibilika kuyafuneka ukumelana nokuqina okungaphezulu kwe-147N.
(7) I-10kV drop-out fuse ifakwe ngaphandle, kwaye umgama phakathi kwezigaba kufuneka ube mkhulu kune-70cm.
Okwesibini, ukusebenza kwefuse yokulahla:
Kwiimeko eziqhelekileyo, akuvumelekanga ukusebenzisa i-fuse ye-drop kunye nomthwalo, kuphela kuvunyelwe ukusebenzisa izixhobo ezingenayo umthwalo (umgca).Nangona kunjalo, imigca yesebe ye-10kV imigca yokusasaza kwiigridi zamandla asemaphandleni kunye neenguqu zokusasaza ezinomthamo olinganisiweyo ongaphantsi kwe-200kVA zivumelekile ukuba zisebenze ngomthwalo ngokwezi mfuno zilandelayo:
(1) Umsebenzi uya kwenziwa ngabantu ababini (omnye wokubeka iliso nomnye ukusebenza), kodwa kufuneka anxibe iiglavu zokhuselo ezisemgangathweni, iibhutsi zokugquma, kunye nezibuko, kwaye asebenze ngeentonga zokhuselo ezisemgangathweni ezinamaqondo ombane ahambelanayo.Umsebenzi awuvumelekanga kwimvula enkulu.
(2) Ngethuba lokusebenza kwesango, ngokuqhelekileyo kuchazwe ukuba isigaba esiphakathi sitsalwa kuqala, emva koko isigaba se-leeward siyatsalwa, kwaye emva koko isigaba somoya siyatsalwa.Oku kungenxa yokuba i-transformer yokusabalalisa iguqulwa ukusuka kwisigaba sesithathu ukuya kwisigaba sesibini, kwaye i-arc spark eyenziwa xa isigaba esiphakathi siphukile sincinci, esingayi kubangela isiphaluka esifutshane phakathi kwezigaba.Okwesibini kukwaphula isigaba secala leeward, kuba isigaba esiphakathi sitsaliwe, kwaye umgama phakathi kwesigaba se-leeward kunye nesigaba somoya uphindwe kabini.Nangona kukho i-overvoltage, ithuba lokujikeleza okufutshane phakathi kwezigaba lincinci kakhulu.Xa inqanaba elijonge ngasemoyeni litsalwa ngasemva, kukho umsinga wecapacitive kuphela emhlabeni, kunye nentlantsi eveliswayo incinci kakhulu.
(3) Xa uvala, ulandelelwano lomsebenzi lubuyiselwa umva xa uvala, vala kuqala inqanaba elijonge umoya, emva koko uvale isigaba se-leeward, uze uvale isigaba esiphakathi.
(4) Ukusebenza ityhubhu enyibilikayo yinto eqhelekileyo.Ukuba awuyi kuqwalasela, kuya kubangela ukuba uqhagamshelwano lutshise kwaye lubangele uqhagamshelwano olubi, lugqithise uqhagamshelwano, kunye ne-anneal entwasahlobo, eya kwenza ukuba umfowunelwa abe mandundu kwaye enze isangqa esibi.Ngoko ke, xa utsala kwaye uvala ityhubhu ye-fusion, sebenzisa amandla aphakathi.Emva kokuvala, jonga ngononophelo ukuba ulwimi lwedada lunokubotshwa ngokuqinileyo ngaphezulu kwesibini kwisithathu sobude bolwimi.Ungasebenzisa i-lever yebrake ukuhuka i-duckbill ephezulu kwaye ucinezele phantsi amaxesha ambalwa.Zama ukutsala kwakhona ukujonga ukuba ingena kakuhle na.Xa utshintshi luvaliwe, alukho kwindawo okanye aluvalwanga ngokuqinileyo, kwaye uxinzelelo lwe-static loqhagamshelwano kwi-fuse alunelanga, olunokubangela ukuba umnxibelelwano utshise okanye ityhubhu ye-fuse iwe ngokwayo.
