Ni irihe sano riri hagati yumurongo wambukiranya umugozi numuyoboro wa kabili, kandi ni ubuhe buryo bwo kubara?

Ubusanzwe insinga zitwa "insinga".Nibitwara byohereza ingufu zamashanyarazi kandi nuburyo bwibanze bwo gukora imirongo hagati yibikoresho byamashanyarazi.Ibice byingenzi byo kohereza insinga mubisanzwe bikozwe mubikoresho byumuringa cyangwa aluminium.

Igiciro cyinsinga zikoreshwa mubikorwa bitandukanye ziratandukanye.Kurugero, ibikoresho byicyuma byagaciro ntibikoreshwa gake nkinsinga.Insinga zirashobora kandi kugabanywa ukurikije ibisabwa.Kurugero, niba ikigezweho ari kinini, tuzakoresha insinga ndende.

Kubwibyo, insinga ziroroshye cyane mubikorwa bifatika.Noneho, mugihe duhisemo kugura, ni ubuhe bwoko byanze bikunze bibaho hagati ya diameter ya wire nubu.

Isano iri hagati ya diameter ya wire nubu

Mubuzima bwacu bwa buri munsi, insinga zisanzwe ni nto cyane.Impamvu nuko ikigezweho bitwaza iyo bakora ari gito cyane.Muri sisitemu yingufu, ibisohoka byumuvuduko muke wa voltage kuruhande rwa transformateur mubusanzwe ni igiteranyo cyumuvuduko ukoreshwa nuwukoresha, kuva kuri amper amajana make kugeza kubihumbi amperes.

Noneho duhitamo diameter nini ya diameter kugirango duhuze ubushobozi burenze urugero.Ikigaragara ni uko diameter ya wire ihwanye nubu, ni ukuvuga ko nini nini, nini cyane igice cyambukiranya insinga.

Isano iri hagati yumurongo wambukiranya insinga nubu iragaragara cyane.Ubushobozi bwo gutwara insinga nabwo bujyanye nubushyuhe.Ubushyuhe buringaniye, niko kurwanya insinga, niko birwanya imbaraga, kandi niko gukoresha ingufu nyinshi.

Kubwibyo, mubijyanye no guhitamo, turagerageza guhitamo umugozi munini cyane ugereranije numuyoboro wagenwe, ushobora kwirinda neza ibintu byavuzwe haruguru.

Agace kambukiranya insinga muri rusange kabarwa ukurikije formula ikurikira:

Umugozi wumuringa: S = (IL) / (54.4 △ U)

Umugozi wa aluminium: S = (IL) / (34 △ U)

Aho: I - Umuyoboro ntarengwa unyura mu nsinga (A)

L - Uburebure bw'insinga (M)

U - Byemerera kugabanuka kwa voltage (V)

S - Agace kambukiranya insinga (MM2)

Umuyoboro ushobora kunyura mubisanzwe byambukiranya igice cyinsinga urashobora gutoranywa ukurikije umubare wamashanyarazi ukeneye gukora, ushobora kugenwa mubisanzwe ukurikije jingle ikurikira:

Injyana ya wire yambukiranya agace hamwe nubu

Icumi ni eshanu, ijana ni ebyiri, ebyiri eshanu eshatu eshatu eshanu enye imbibi eshatu, mirongo irindwi n'icyenda eshanu kabiri nigice, kubara insinga z'umuringa kubara

Ku nsinga za aluminiyumu munsi ya mm 10, gwiza milimetero kare kuri 5 kugirango umenye ampere yubu yumutwaro utekanye.Ku nsinga ziri hejuru ya milimetero kare 100, kugwiza igice cyambukiranya ibice 2;ku nsinga ziri munsi ya milimetero 25, kugwiza na 4;ku nsinga ziri hejuru ya milimetero 35, kugwiza na 3;ku nsinga ziri hagati ya milimetero 70 na 95, kugwiza na 2.5.Ku nsinga z'umuringa, uzamuke urwego, urugero, milimetero kare 2,5 z'insinga z'umuringa zibarwa nka milimetero kare 4.(Icyitonderwa: Ibyavuzwe haruguru birashobora gukoreshwa gusa nk'ikigereranyo kandi ntabwo ari ukuri.)

Mubyongeyeho, niba ari mumazu, ibuka ko kubitsinga byumuringa bifite intangiriro yibice bitambutse munsi ya 6 mm2, ni byiza niba ikigezweho kuri milimetero kare kitarenze 10A.

Muri metero 10, ubucucike bw'insinga buriho ni 6A / mm2, metero 10-50, 3A / mm2, metero 50-200, 2A / mm2, na munsi ya 1A / mm2 ku nsinga ziri hejuru ya metero 500.Inzitizi y'insinga iragereranya n'uburebure bwayo kandi ihwanye na diametre yayo.Nyamuneka nyamuneka witondere cyane ibikoresho bya wire na diameter mugihe ukoresheje amashanyarazi.Kugirango wirinde umuyaga mwinshi gushyushya insinga no guteza impanuka.
