Isishwankathelo
I-RW12 series drop-out fuses zizixhobo zokukhusela zangaphandle eziphezulu ze-voltage kukuhanjiswa kwamandla kunye neenkqubo zokusasazwa.Zifakwe kwicala eliphezulu le-voltage ye-transformers yokusabalalisa okanye imigca yesebe yemigca yokusabalalisa i-short-circuit kunye nokukhuselwa komthwalo ogqithisiweyo we-transformers kunye nemigca, kunye nokucima kunye nokudibanisa imisinga yomthwalo.I-fuse ye-ceramic drop-out ye-voltage ephezulu iqukethe i-ceramic insulating bracket kunye ne-fuse tube.Abafowunelwa be-static bafakwe kuzo zombini iziphelo ze-bracket ye-insulating, kwaye oonxibelelwano abahambayo bafakwe kuzo zombini iziphelo zetyhubhu ye-fuse.Ityhubhu ye-fuse iqulethe ityhubhu yokucinezela i-arc yangaphakathi kunye netyhubhu ye-fuse.Umaleko wangaphandle wenziwa ityhubhu yephepha lephenolic okanye ityhubhu yelaphu yeglasi epoxy.
Iimbonakalo
Ubume betyhubhu enyibilikayo:
I-fuse yenziwe nge-flberglsaa, enokufuma kunye ne-corrosion resistant.
Isiseko se-Fuse:
Isiseko semveliso sifakwe kunye nezakhiwo zomatshini kunye ne-insulators.Intonga yentsimbi ifakwe kunye nezinto ezikhethekileyo zokubambelela kunye ne-insulator, enokumelana nombane omfutshane wokuvula amandla.
I-fuse enobungqina bobumanzi ayinamaqamza, ayinayo i-deformation, ayikho isiphaluka evulekileyo, umthamo omkhulu, i-anti-ultraviolet, ubomi obude, iipropati eziphezulu zombane, amandla e-dielectric kunye nokuqina komatshini kunye nokukwazi ukuzinikela.
Yonke inkqubo ayithathi hlangothi, kulula ukuyifaka, ikhuselekile kwaye inokuthenjwa.
Ukufakwa kweefusi zokuyeka
(1) Ukunyibilika kufuneka kuqiniswe ngexesha lofakelo (ukuze inyibilike ikwazi ukumelana ne-tensile force malunga ne-24.5N), ngaphandle koko kulula ukubangela ukuba abafowunelwa bagqithise.
(2) I-fuse efakwe kwingalo yomnqamlezo (ifreyimu) kufuneka iqine kwaye ithembeke, kwaye akufanele kubekho ukugubha okanye ukugubha.
(3) Umbhobho wokunyibilika kufuneka ube ne-engile yokuthambekela ezantsi eyi-25 ° ± 2 °, ukuze ityhubhu yokunyibilika ikhawuleze iwe phantsi ngobunzima bayo xa ivuthela inyibilika.
(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 otyhidiweyo kwakhokelela kwezinye iingozi.
(5) Ubude be-fuse kufuneka bulungiswe ngokufanelekileyo.Kuyafuneka ukuba i-duckbill ikwazi ukugcina ngaphezulu kwesibini kwisithathu sobude boqhagamshelwano emva kokuvala, ukuze kuthintelwe ukuziphambanisa ngokwalo ngexesha lokusebenza, kwaye ityhubhu ye-fuse kufuneka ingabetheli i-duckbill., ukuthintela ityhubhu enyibilikayo ukuba ingawi ngexesha emva kokuba inyibilika ivuthelwe.
(6) Inyibilika esetyenzisiweyo kufuneka ibe yimveliso eqhelekileyo yomenzi oqhelekileyo kwaye ibe namandla athile omatshini.Ngokuqhelekileyo kuyafuneka ukuba inyibilika ikwazi ukumelana ne-tensile force engaphezulu kwe-147N.
(7) I-10kV drop-out fuses zifakwe ngaphandle, kwaye umgama uyafuneka ube mkhulu kuno-70cm.
