Yintoni short circuit sombane?

Nabani na umsebenzi zigazi edibene nenkonzo yombane, wazi kakuhle iingxaki lithwala a elifutshane yesekethe (circuit short). Maxa wambi kucingwa ukuba yonakele. Oku akunjalo. wesekethe elifutshane - yinkqubo, okanye ukuba ungathanda, umsebenzi likaxakeka nayiphi na inxalenye ufakelo. Kodwa ke neziphumo okunene kungakhokelela kumonakalo. Le nkcazelo eyamkelekileyo ifundeka ngolu hlobo: "Mfutshane Circuit - uqhagamshelwano ngqo phakathi kweendawo ezimbini okanye ngaphezulu wesekethe, ukuba nekhono ezahlukeneyo. Aziqhelekanga (nemivuzo) indlela yokusebenza. "

Ukuze siqonde oko kwenzekayo kwisekethe ngalo mzuzu xa kukho circuit emfutshane, kuyimfuneko ukuba ukukhumbula imigaqo yokusebenza ye elements wesiphaluka. Ubonise isekethi elula eziquka unikezelo lwamandla, kwezinikezeli amabini kunye nomthwalo (umz, iibhalbhu ukukhanya). Phantsi kweemeko eziqhelekileyo, kukho umqhubi yintshukumo kwe amasuntswana nezakhiwo abekwe, ngenxa yokuba sesichengeni rhoqo kwi yomkhosi electromotive umthombo. Betshintshatshintsha kwipali omnye komnye umthombo kumacandelo amabini kwala macingo isibane. Ngako oko, isibane, ikhala ukukhanya, ekubeni amasuntswana ukwenza umsebenzi othile.

Xa alternating current indlela yokuhamba esoloko itshintsha, kodwa kule meko kwaye ayinamsebenzi. Inani elektroni edlula uluhlu lwamajelo chain nganye ixesha iyunithi anqongophele ngenxa umthombo ukumelana isibane abaqhubi of EMF. Ngamanye amazwi, le yangoku lungakhuli ngonaphakade, kodwa ekwafanekisa kurhulumente ngcembe.

Kodwa ngoku, ngenxa yaso nasiphi na isizathu, zonakaliswe ezisongwayo kwi kwindawo wesekethe. Umzekelo, isibane lakhukuliswa ngamanzi. Kulo mzekelo yayo ukuxhathisa lombane kunciphisa. Ngenxa yomtya yangoku yangoku anqongophele netotali wire ukumelana umbane kunye "kwisiqwenga somhlaba 'zolwelo kwi isibane. Ngokuqhelekileyo le mali babambanayo mncinci kakhulu, ukuba izibalo musa ithathele ingqalelo (ngaphandle becomputing ezizodwa).

Isiphumo ukukhula phantse infinite ngoku, njengoko kulinganiswa ngokomthetho weklasiki Ohm kaThixo. Kulo mzekelo, obizwa amandla mfutshane-wesekethe. Oku kumiselwa ixabiso umda we umbane, onako ukunika unikezelo amandla ukusilela. Ngendlela, ukuba Akuvunyelwe ukuqhagamshela iingcingo (short-yesekethe) abafowunelwa eziphikisanayo iibhetri.

Nangona lo mzekelo siqwalasela ukususwa chain ngenxa kokungena uxhathiso wamanzi ityhubhu, kukho ezininzi yezizathu zokhuselo elifutshane-wesekethe. Ngokomzekelo, xa sithetha ngeskim enye, ixesha elifutshane kunye wesekethe Kwakhona kuthi ukuba kuncinci ukwambathisa yaphulwe wire enye ubuncinane, kwaye yarweca emhlabeni. Kulo mzekelo, i yangoku kususela unikezelo mbane kuya kulandela indlela ezilu-, ngamanye emhlabeni, ukuba omkhulu umthamo. Umonakalo ubushushu of ababhexeshi amabini kunye zoqhagamshelwano kwabo kuya kukhokelela kwisiphumo efanayo.

Le nkqubo ingentla iya ingashwankathelwa: KZ inokuba ilizwe ngaphandle kwayo. Kwi iinkqubo aziphazamiseki.

Loluphi uhlobo umonakalo njengoko kuchaziwe ekuqaleni kweli nqaku? Njengoko yaziwa, kungona ixabiso yangoku elibaleka ngokwamacandelo zeesekethe, kokukhona zokufudumeza wabo. Xa umthombo ezaneleyo amandla xa short-circuit Ezinye iinxalenye chain aqhumisele nje, ajike abe ngobhedu yangumgubo (isiqalelo zobhedu).

Ukukhuselwa ngokuchasene short-beesekethe ilula nesebenzayo. Iingxelo wentshabalalo ngenxa nandzu kuvela ubukhulu becala ngenxa yemida ephosakeleyo-ahleliweyo izixhobo zokhuselo, selectivity ezingachanekanga. Xa kufikwa wesekethe indlu 220, ngoko sebenzisa breakers beesekethe. In kubo ukukhululwa kakhulu ukwanda solenoid lwangoku, ibekwe ngaphakathi kuqhume chain.
