Kachulukidwe panopa

Normal moyo vuto - m'pofunika kukhazikitsa lophimba latsopano kapena kubwereketsa mu dziko. Zonsezi - zitsulo, waya, fasteners, anasankha malo unsembe. Kuchitenga icho ndi kuchita izo. Koma palibe! Ine ndinayiwala onani, ndipo ine ntchito waya angakhale alipo? Kudziwa kufunika zotheka kugwiritsa ntchito mawu monga kachulukidwe panopa, ndi kupeza phindu lake kololeka.

Kodi chithunzi ichi, ndi chifukwa chake kuli kofunika? Akukhulupirira kuti atakumana zachibadwa za mphamvu ya magetsi umadutsa buku lonse la wochititsa lapansi. Simplistically - mtengo wa panopa likuyenderera mu chigawo wochititsa imatengedwa kachulukidwe ake. Choyezera ake mu dongosolo SI amagwiritsa chotero unit ampere pa mita lalikulu (A / m), ndipo ndi chovomerezeka kukhazikitsa pamene ukuyenda mwa waya panopa.

amafuna Kodi zimenezi? Ndi yosavuta. Aliyense wochititsa ali ndi kukana kwa otaya panopa, umene ndi "anataya" gawo. Izi "anataya" zimayambitsa panopa Kutentha kwa wochititsa lapansi. Ngati zomvetsa lalikulu anatsatira pambuyo ndi kutentha kwambiri wochititsa, ndipo chimasungunula. Kuti izi sizinali, kwa mtundu uliwonse wa chida wayikidwa chovomerezeka kachulukidwe panopa, kugwilizana ndi amene adzaonetsetsa opareshoni odalirika Kulumikizana ndi.

Izo ziyenera tsopano chicodziwika kuti anasankha bwino mbali wochititsa ndi, i.e. akuyenera kugwiritsa ntchito katundu, omwe amadya mphamvu kwambiri, kapena onse monga zipangizo zingapo banja (ketulo, computer, TV, etc.), otaya panopa adzachititsa Kutentha kwambiri za mawaya, ndipo kusungunula. Kapena kukhala chifukwa cha moto.

Ndicho chifukwa kusankha wochititsa mtanda zigawo, kapena ngati wina aliyense, pamene kugwirizana katundu zakonzedwa, m'pofunika kuganizira chovomerezeka panopa osalimba. Pogwira kapangidwe ntchito kwa cholinga kuti mitunduyi wapadera ndi matebulo ntchito ndi akatswiri. Komabe, mawerengedwe Chigawo cha waya pa kololeka kachulukidwe panopa amapereka zovomerezeka kwa mfundo za view zotsatira.

Kuti zimenezi zitheke, si koyenera kugwiritsa ntchito njira zinazake zovuta spreadsheets wolemera. Ndikofunikira kuganizira kufunika chomwecho - osalimba ziliri pa waya mkuwa sayenera upambana amperes sikisi khumi pa sq. millimeter. Deta pamwamba chomveka kwa mkuwa. Monga tsopano ntchito makamaka mawaya mkuwa, deta awa ayenera kokwanira kudziwa applicability ake.

Chiwerengerochi ayenera kuzindikiridwa motere. Ntchito yothandizira osalimba ziliri pa dera sayenera upambana 6 A / sq. mm. Ndiye, Kulumikizana adzathamanga mu mode Lite, ndipo angagwiritsidwe ntchito kwa nthawi yaitali. Komabe, mwina opareshoni mu Mafilimu angaphunzitse 10 A / sq. mm, koma ulamuliro akhale sakhalitsa.

Monga muyika mumachitidwe? M'pofunika kudziwa pazipita chikugwirizana katundu. Zilekeni Mwachitsanzo, nthawi yomweyo amaphatikiza ndi chandelier magetsi asanu 100 Watts, TV, kompyuta, firiji. The munkalowa wa osapitirira 5 kW, gawani chithunzi ichi ndi mains voteji, 5,000 Watts akufufuta 220, timapeza kanjedza wozungulira 23a. Tanthauzo kupereka yochepa ntchito ngati panopa ndimeyi chofunika mkuwa waya 2.5kb. millimeter.

Mutha kulankhula nkhani imeneyi m'njira yosiyana. Ngati kubwereketsa kwalembedwa kuti lakonzedwa 6a ulipo, ndiye kuti ntchito mkuwa waya kuposa wina lalikulu. mamilimita Sikuti, ndi zitsulo anatentha patsogolo. Monga mumve - ngati udindo wa zinthu conductive ndi zotayidwa, ndi chovomerezeka kachulukidwe panopa ndi 4-6 A / sq. mm. Choncho, ntchito ziphiphiritso zimenezi, mukhoza kudziwa zimene gawo la waya ayenera kugwiritsidwa ntchito Kulumikizana chipangizo.

Nkhani tatchulawa amapereka tanthauzo la mfundo "kachulukidwe panopa". Iwo anafotokoza kufunika kwa ntchito yake kusankha kufunika waya kukula. Kuvomereza zothandiza pa ntchito ya chizindikiro ichi pa ntchito.
