Fuse, izwi cyane nkubwishingizi, nikimwe mubikoresho byoroshye birinda amashanyarazi.Iyo ibikoresho by'amashanyarazi muri gride yamashanyarazi cyangwa imizigo irenze urugero cyangwa umuzunguruko mugufi bibaye, irashobora gushonga no kumenagura umuzunguruko ubwayo, ikirinda umuyagankuba hamwe nibikoresho by amashanyarazi byangiritse bitewe nubushyuhe bwumuriro wamashanyarazi arenze urugero, kandi bikabuza ikwirakwizwa rya impanuka.
Imwe, icyitegererezo cya fuse
Inyuguti ya mbere R isobanura fuse.
Inyuguti ya kabiri M isobanura ko nta gupakira gufunga ubwoko bwa tube;
T bisobanura ubwoko bwafunze ubwoko bwa tube;
L bisobanura kuzunguruka;
S bisobanura uburyo bwihuse;
C igereranya kwinjiza farashi;
Z bisobanura kwigira.
Icya gatatu nigishushanyo mbonera cya fuse.
Iya kane yerekana igipimo cyagenwe cya fuse.
Babiri, gutondekanya fus
Ukurikije imiterere, fus irashobora kugabanywamo ibyiciro bitatu: ubwoko bwuguruye, ubwoko bwafunze igice nubwoko bufunze.
1. Fungura ubwoko bwa fuse
Iyo gushonga bitagabanya urumuri rwa arc hamwe nicyuma cyo gushonga ibyuma byo gusohora, gusa bikwiranye no guhagarika imiyoboro migufi yumuzunguruko ntabwo ari inshuro nini, iyi fuse ikoreshwa kenshi hamwe no guhinduranya icyuma.
2. Fuse ifunze
Fuse yashizwe mumiyoboro, hanyuma impera imwe cyangwa impande zombi zarafunguwe.Iyo fuse yashongeshejwe, urumuri rwa arc hamwe nuduce duto two gushonga ibyuma bisohoka mu cyerekezo runaka, bigabanya ibikomere bimwe nabakozi, ariko biracyafite umutekano uhagije kandi imikoreshereze igarukira kurwego runaka.
3. Fuse ifunze
Fuse ifunze rwose mugikonoshwa, nta gusohora arc, kandi ntabwo bizatera akaga igice kizima cyegereye arc n'abakozi bari hafi.
Bitatu, imiterere ya fuse
Fuse igizwe ahanini no gushonga hamwe na fuse tube cyangwa fuse ifite feri yashizwemo.
1.Gushonga nigice cyingenzi cya fuse, akenshi bikozwe mubudodo cyangwa urupapuro.Hariho ubwoko bubiri bwibikoresho bishonga, kimwe ni ibikoresho byo gushonga hasi, nka gurş, zinc, amabati na tin-gurş;Ibindi ni ibikoresho byo gushonga cyane, nka feza n'umuringa.
2.Umuyoboro ushonga nigikonoshwa kirinda gushonga, kandi gifite ingaruka zo kuzimya arc mugihe gushonga byahujwe.
Bane, ibipimo bya fuse
Ibipimo bya fuse bivuga ibipimo bya fuse cyangwa fuse ufite, ntabwo ibipimo bya melt.
1. Gushonga ibipimo
Gushonga bifite ibipimo bibiri, ibipimo byagenwe hamwe nuyoboro uhuza.Ikigereranyo cyagenwe bivuga agaciro k'umuyaga unyura muri fuse igihe kirekire utarinze.Umuyoboro wa fuse mubusanzwe wikubye kabiri igipimo cyagenwe, mubisanzwe unyuze mumashanyarazi ushonga inshuro 1,3 yumuvuduko wagenwe, ugomba guhuzwa mumasaha arenze imwe;Inshuro 1.6, bigomba guhuzwa mugihe cyisaha imwe;Iyo fuse igeze, fuse iracika nyuma yamasegonda 30 ~ 40;Iyo inshuro 9 ~ 10 zagabanijwe zagerwaho, gushonga bigomba gucika ako kanya.Gushonga bifite uburinzi buranga igihe cyinyuma, nini nini igenda inyura mumashanyarazi, nigihe gito cyo guhuza.
2. Ibikoresho byo gusudira
Fuse ifite ibipimo bitatu, aribyo voltage yagenwe, igipimo cyagenwe nubushobozi bwo guca.
1) Umuvuduko wagenwe urasabwa kuva muri Angle yo kuzimya arc.Iyo voltage ikora ya fuse iruta voltage yagenwe, hashobora kubaho akaga ko arc idashobora kuzimya mugihe gushonga kumenetse.
2. ntukabe hejuru yikigereranyo cyagenwe cyumuyoboro ushongeshejwe.
3) Ubushobozi bwo gukata nigiciro ntarengwa kigezweho gishobora gucibwa mugihe fuse ihagaritswe nikibazo cyumuzunguruko kuri voltage yagenwe.
Icya gatanu, ihame ryakazi rya fuse
Inzira yo guhuza fuse igabanijwemo ibice bine:
1. Gushonga biri murukurikirane rwumuzunguruko, kandi umutwaro wumutwaro unyura mumashanyarazi.Bitewe nubushyuhe bwubushyuhe bwumuyaga bizatuma ubushyuhe bwashonga buzamuka, mugihe umuvuduko ukabije wumuzunguruko cyangwa umuzunguruko mugufi bibaye, umuyagankuba urenze cyangwa umuyagankuba mugufi bizatuma gushonga bikabije kandi bigere kubushyuhe bwo gushonga.Iyo umuyaga uri hejuru, ubushyuhe burazamuka vuba.
2. Gushonga bizashonga kandi bihinduke umwuka mubyuma nyuma yo kugera kubushyuhe.Nibisanzwe hejuru, bigufi igihe cyo gushonga.
3. Mu gihe gushonga gushonga, hari icyuho gito cyo gukumira mu muzunguruko, kandi umuyaga uhagarara gitunguranye.Ariko iki cyuho gito gihita gisenywa na voltage yumuzunguruko, hanyuma havuka arc amashanyarazi, nayo igahuza uruziga.
4. Nyuma ya arc ibaye, niba ingufu zigabanutse, izizimya hamwe no kwaguka icyuho cya fuse, ariko igomba gushingira kubikorwa byo kuzimya fuse mugihe ingufu ari nini.Kugirango ugabanye arc kuzimya igihe no kongera ubushobozi bwo kumena, fus nini nini zifite ibikoresho byiza byo kuzimya arc.Ninini nini yo kuzimya arc nubushobozi bwihuse, arc irazimya vuba, kandi nini nini ya miyoboro ngufi irashobora gucika na fuse.
Gatandatu, guhitamo fuse
1. Hitamo fuse ifite urwego rujyanye na voltage ukurikije amashanyarazi ya gride;
2. Hitamo fuse ifite ubushobozi bwo kumeneka ukurikije ikosa ntarengwa rishobora kugaragara muri sisitemu yo gukwirakwiza;
3, fuse mumuzunguruko wa moteri kugirango irinde umuzunguruko mugufi, kugirango wirinde moteri mugikorwa cyo gutangira fuse, kuri moteri imwe, umuyagankuba wagenwe ushonga ntugomba kuba munsi yinshuro 1.5 ~ 2,5 ya moteri;Kuri moteri nyinshi, igiteranyo cyashongeshejwe ntigishobora kuba munsi yikigereranyo cya 1.5 ~ 2,5 cyumubyigano wa moteri ntarengwa wongeyeho umutwaro wabazwe wa moteri isigaye.
4. Kubirinda-bigufi kurinda urumuri cyangwa itanura ryamashanyarazi nindi mizigo, umuyagankuba wagenwe ushonga ugomba kuba uhwanye cyangwa uruta gato ugereranije numuyoboro wagenwe wumutwaro.
5. Iyo ukoresheje fus kugirango urinde imirongo, fus igomba gushyirwaho kuri buri murongo.Birabujijwe gushyira fuse kumurongo utabogamye mubice bibiri-bitatu-bitatu cyangwa ibyiciro bitatu-bine byumuzunguruko, kubera ko umurongo utabogamye uzatera ubusumbane bwa voltage, bushobora gutwika ibikoresho byamashanyarazi.Ku murongo umwe wicyiciro gitangwa na gride rusange, fus igomba gushyirwaho kumurongo utabogamye, ukuyemo fuse yose ya gride.
6. Inzego zose za fus zigomba gufatanya mugihe zikoreshwa, kandi igipimo cyagenwe cyo gushonga kigomba kuba gito ugereranije nurwego rwo hejuru.
