Isishwankathelo
I-fuse yokulahla kunye ne-fuse yokutshintsha umthwalo zizixhobo ezingaphandle zokukhusela i-voltage ephezulu.Zixhunyiwe kumgca ongenayo okanye umgca wokusabalalisa we-transformer yokusabalalisa.Ezi zisetyenziselwa kakhulu ukukhusela i-transformers okanye imigca ukusuka kwisiphaluka esifutshane, ukulayisha ngaphezulu kunye nokutshintsha okwangoku.I-fuse yokulahla iquka isibiyeli se-insulator kunye netyhubhu ye-fuse.Abafowunelwa be-static baqiniswe kumacala omabini e-insulator bracket, kwaye oonxibelelwano oluhambayo bafakwe kuzo zombini iziphelo zetyhubhu ye-fuse.Ngaphakathi kwityhubhu yefuse kukho ithumbu lomlilo.Umphandle wenziwa ityhubhu yephepha edibeneyo yephenolic okanye iglasi ye-epoxy.I-fuse yokutshintsha umthwalo ibonelela ngoqhagamshelwano oluncedisayo kunye ne-arc yokucima ukuvalwa kwegumbi lokuvula / ukuvala umthwalo wangoku.
Ngethuba lokusebenza okuqhelekileyo, i-fuse itsalwa kwindawo evaliweyo.Ngaphantsi kweemeko zangoku eziphosakeleyo, ikhonkco ye-fuse iyanyibilika kwaye yenza i-arc.Le yimeko yegumbi lokucima i-arc.Oku kudala uxinzelelo oluphezulu kwi-tube kwaye kubangela ukuba ityhubhu ihlukane nabafowunelwa.Emva kokuba i-fuse inyibilika, amandla abafowunelwa aya kuphumla.I-breaker circuit ngoku ikwindawo evulekileyo kwaye umqhubi kufuneka acime okwangoku.Abafowunelwa abashukumayo banokutsalwa kusetyenziswa iileva ezigqunyiweyo.Uqhagamshelwano oluphambili kunye noqhagamshelwano oluncedisayo luxhunyiwe.

(1) Ukuze kwenziwe ifyuzi isebenze ngokuthembekileyo nangokukhuseleka ngakumbi, ukongeza ekukhetheni ngokungqongqo iimveliso ezifanelekileyo kunye nezincedisi (kubandakanywa iindawo ezixubeneyo) eziveliswe ngabavelisi abasemthethweni ngokweemfuno zemimiselo, le miba ilandelayo iya kunikwa ingqwalasela eyodwa. kulawulo lokusebenza kunye nokugcinwa:
① Jonga ukuba umsinga okaliwe wefuse uyahambelana na nenyibilika kwaye ulayishe amaxabiso angoku ngokufanelekileyo.Ukuba ukuhambelana akufanelekile, kufuneka kulungiswe.
② Umsebenzi ngamnye wefuse kufuneka ulumke kwaye ulumke, ungakhathali, ngakumbi umsebenzi wokuvala.Abafowunelwa abaguqukayo kunye nabazinzileyo kufuneka banxibelelane kakuhle.
③ Umgangatho wokunyibilika kufuneka usetyenziswe kumbhobho wokunyibilika.Akuvumelekanga ukusebenzisa ucingo lobhedu kunye nocingo lwe-aluminium endaweni yokuncibilika, kwaye akuvumelekanga ukusebenzisa ucingo lobhedu, ucingo lwe-aluminium kunye nentsimbi yentsimbi ukubopha umnxibelelwano.
④ Kwii-fuses ezisanda kufakwa okanye ezitshintshwe, inkqubo yokwamkelwa iya kwenziwa ngokungqongqo, kwaye iimfuno zomgangatho wemigaqo kufuneka zifezekiswe.I-angle yokufakela ityhubhu ye-fuse iya kufikelela malunga ne-25 °.
⑤ Ukunyibilika okudityanisiweyo kuya kutshintshwa kufakwe entsha ngokweenkcukacha ezifanayo.Akuvumelekanga ukudibanisa i-melt edibeneyo kwaye uyifake kwi-tube yokunyibilika ukuze isetyenziswe ngakumbi.
⑥ I-fuse kufuneka ihlolwe rhoqo, kanye ngenyanga ebusuku, ukukhangela ukuba akukho ntlantsi yokukhupha kunye nokudibana kakubi.Ukuba kukho ukukhutshwa, kuya kubakho ingxolo yokukhwaza, ekufuneka iphathwe ngokukhawuleza.
(2) Olu hlolo lulandelayo luya kwenzelwa i-fuses ngexesha lokuhlolwa kwentwasahlobo kunye nokugcinwa kokucima:
① Nokuba unxibelelwano phakathi koqhagamshelwano olusisigxina kunye noqhagamshelwano olushukumayo luyahambelana, luqinile kwaye aluguquki, kunye nokuba kukho uphawu lokutsha.
② Ingaba iindawo ezijikelezayo ze-fuse ziguquguqukayo, zinomhlwa, aziguquki, njl.
③ Nokuba inyibilika ngokwayo yonakele okanye hayi, kwaye ingaba kukho ukufudumeza okugqithisileyo kobude kwaye iba buthathaka emva kokukhanyisa ixesha elide.
④ Ingaba i-arc yokucinezela ityhubhu yokuvelisa igesi kwityhubhu yokunyibilika iyatshiswa, yonakaliswe kwaye ikhubazeke emva kokuvezwa elangeni nemvula, nokuba ubude bufutshane emva kwezenzo ezininzi.
⑤ Coca i-insulator kwaye ukhangele ukuba kukho umonakalo, ukuqhekeka okanye ukukhupha umkhondo.Emva kokususa izikhokelo eziphezulu kunye nezantsi, sebenzisa i-2500V megger ukuvavanya ukuchasana kwe-insulation, okufuneka kube mkhulu kune-300M Ω.
⑥ Jonga ukuba ngaba umkhombandlela ophezulu nasezantsi wokuqhagamshela wefuse ukhululekile, ukhutshiwe okanye ushushu kakhulu.
Iziphene ezifunyenwe kwezi zinto zingentla kufuneka zilungiswe ngononophelo kwaye ziphathwe.
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.
