Xa ibeka i-wiring kufuneka ukwazi, intambo kunye nezimbobo zeliphi icandelo oya kuzo. Ukukhethwa kwecandelo lomnqamlezo lwentambo kunokwenziwa ngamandla asetyenzisiweyo, okanye ngokutyiwa okukhoyo. Qwalasela ubude bentambo kunye nendlela ebilayo.
Khetha icandelo le-cable
Unokukhetha icandelo le-wire kumandla eendawo eziza kuqhagamshelwa. Ezi zixhobo zibizwa ngokuba ngumthwalo kwaye le ndlela isenokubizwa ngokuba "kumthwalo". Isiseko sayo asitshintshi.
Ukukhethwa kwecandelo lomnqamlezo wentambo kuxhomekeke kumandla kunye namandla okho
Siqokelela idatha
Ukuqala, sifumana idatha yencwadana yokundwendwela yezixhobo zombane zasekhaya ezigqithayo, yibhale phantsi kwincwadana enemifanekiso. Ukuba kulula kakhulu, unokujonga amagama-iipleyiti zentsimbi okanye izitikha ezixhonywe kwiqumrhu lezixhobo kunye nezixhobo. Kukho ulwazi olusisiseko kwaye, kaninzi, amandla akhoyo. Ukuchonga kulula ziiyunithi zemilinganiselo. Ukuba imveliso yenziwa eRussia, i-Belarus, iUkraine ihlala ifanelekile ukuba i-WHEAME okanye isixhobo esivela eYurophu, i-Asia okanye iMelika, idla ngokuba sisiNgesi se-Watts - w, kunye nokusetyenziswa kwamandla (kuyafuneka ) Ichazwa kukuncitshiswa kwe "I-Tender" okanye i-max max.
Imeyilisi yegama lolwazi olusisiseko lobugcisa. Into efanayo nakweyiphi na indlela
Ukuba lo mthombo awufumaneki (lo lwazi lwalahleka, umzekelo, okanye ucwangcisa ukufumana izixhobo, kodwa awukagqitywa ngemodeli), ungathatha idatha ephakathi. Ukuze zilungele, zincitshisiwe, ziye etafileni.
Itheyibhile yamandla etyiwa kwezixhobo ezahlukeneyo zombane
Fumana indlela oceba ukuyibeka, bhala amandla. Ngamanye amaxesha inikezwe isacithi esikhulu, ngenxa yoko ngamanye amaxesha kunzima ukuyiqonda ukuba leliphi inani lokuthatha. Kule meko, kungcono ukuthatha ubuninzi. Ngenxa yoko, ngexesha lokubala, uya kuba namandla aphezulu kakhulu kwezixhobo kwaye intambo enkulu iya kufuneka. Kodwa ukubala icandelo lekhebula lilungile. Iintambo kuphela ezivuthayo ngecandelo elincinci lomnqamlezo kunokuba liyimfuneko. Iitrekhi ezinamacandelo amakhulu omnqamlezo ixesha elide, njengoko zifudumele.
Inqaku lendlela
Ukukhetha icandelo lomnqamlezo lomthwalo kulo mthwalo, faka amandla kwizixhobo eziza kuqhagamshelwa kulo mfundo. Kubalulekile ukuba onke amandla abonakaliswa kwiiyunithi zemilinganiselo efanayo-okanye kwii-watts (w), okanye kwii-kilowatts (kW). Ukuba kukho intsingiselo eyahlukileyo, zisa nesiphumo esinye. Ukuguqulela, i-Kiwatta iphindaphindwe nge-1000, kwaye i-watts ifunyenwe. Umzekelo, i-1,5 kw izakutshintshelwa kwi-watta. Iya kuba yi-1.5 KW * 1000 = 1500 W.Inqaku ngesihloko: Indlela yokuhombisa igadi, ikhaya, i-cottage plat (iifoto ezingama-50)
Ukuba kukho imfuneko, unokutshintsha iguquko - ii-watts ziguqulela kwii-kilowatts. Kule, inani le-watts lahluleke nge-1000, sifumana i-KW. Umzekelo, i-500 w / 1000 = 0.5 kw.
Ngapha koko, enyanisweni, ukhetho lwecandelo lekhebula liqale. Yonke into ilula kakhulu - sisebenzisa itafile.

Ukufumana icandelo le-cable eliyifunayo kwikholamu ehambelana nayo - i-220 v okanye i-380 v - sifumana idijithali elingana okanye engaphezulu kwegunya elibalwe ngaphambili. Ikholamu ikhethwe ngokusisiseko malunga nokuba zingaphi izigaba kwinethiwekhi yakho. Isigaba esinye-220 V, isigaba seSigaba se-380 380 V.
Kwindawo efunyenweyo, sijonga ikholamu yokuqala. Lo iya kuba yicandelo elifunwayo le-cable yomthwalo walo mthwalo (ukusetyenziswa kwamandla kwezixhobo). Intambo kunye namathambo ecandelo elinjalo kwaye kuya kufuneka bajonge.
Kancinci malunga necingo yobhedu okanye i-aluminium. Kwiimeko ezininzi, xa ibeka i-wiring kwindlu okanye indlu, iintambo ezisetyenziswa iintambo zobhedu zisetyenziswa. Iintambo ezinjalo ziyinto ebiza kakhulu i-aluminium, kodwa ziguquguquka ngakumbi, zinecandelo elincinci lomnqamlezo, umsebenzi ube lula nabo. Kodwa, iintambo zobhedu ngecandelo elikhulu lomnqamlezo, akusekho bhetyebhetye kunealuminim. Kwaye kwimithwalo emikhulu-ekungeneni kwendlu, kwigumbi elinamandla amakhulu (ukusuka kwi-10 kw nangaphezulu) kuyabonakala ngakumbi ukusebenzisa intambo kunye nabaqhubi bealuminiyam - ungagcina kancinci.

INDLELA YOKUXELISA INDLELA YOKUZIPHATHA KWENDLELA
Unokukhetha icandelo lentambo. Kule meko, siqhuba umsebenzi ofanayo-siqokelela idatha kwi-plug-kumthwalo, kodwa sikhangela owona sitshetshelwe siphethwe kwimpawu. Ukuqokelela onke amaxabiso, Shwankazisela. Emva koko sisebenzisa itafile efanayo. Kuphela sikhangela kwixabiso eliphezulu kwikholamu esayiniweyo yi "yangoku". Kumgca ofanayo, sijonga icandelo le-wire.
Umzekelo, kufuneka uqhagamshele ipaneli yokupheka kunye ne-piak entywila ye-16 A. Siza kubeka intambo yobhedu, kuba sijonga kwikholamu efanelekileyo - ngasekhohlo. Kuba akukho xabiso kanye nge-16 A, sijonga kumgca we-19 osondeleyo. Icandelo elifanelekileyo 2.0 mm2. Eli iya kuba lelona candelo liphantsi lentambo leli candelo.
Xa uqhagamshela izixhobo zombane ezinamandla zekhaya ezivela kwiflethi, umgca wokuhambisa owahlukileyo uyatsalwa. Kule meko, ukhetho lwecandelo lekhebula lilula kakhulu - ixabiso elinye lamandla okanye langoku liyafuneka.
Awunakho ukunikela ingqalelo kwixabiso elincinci elincinci. Kule meko, ngomthwalo ophezulu, umqhubi wesifundo uya kufudumele ngokufudumeleyo, onokukhokelela ekuzimiseni inyibiba. Yintoni enokwenzeka? Inokusebenza ngokukhuselekileyo ukuba ifakiwe. Le yeyona ndlela intle. Kunokubakho izixhobo zombane zasekhaya okanye umlilo. Ke ngoko, ukukhetha kwecandelo lekhebula kusoloko kwenza ixabiso elikhulu. Kule meko, kuya kuba nakho ukufaka izixhobo kancinci nangakumbi kumandla okanye kuchithwe okwangoku ngaphandle kokubhala kwakhona.
Ukubalwa kwentambo yamandla kunye nobude
Ukuba umgca wombane ubude - ishumi elinambini okanye amakhulu eemitha- ukongeza kumthwalo okanye okwangoku, kunyanzelekile ukuba uthathele ingqalelo ilahleko ngokwayo. Ngokwesiqhelo, imigama emide yemigca yamandla xa ungena ngombane ukusuka kwiposti endlwini. Nangona zonke iinkcukacha kufuneka zidweliswe kule projekthi, unokuphinda uhlolwe kwaye ujonge. Ukwenza oku, kufuneka wazi amandla azinikeleyo endlwini kunye nomgama ukusuka kwisithuba esiya endlwini. Emva koko, etafileni, unokukhetha icandelo lomnqamlezo locingo, kuthathelwa ingqalelo kwilahleko yemali ubude.

Itheyibhile yokuchonga icandelo lentambo yentambo yamandla kunye nobude
Ngokubanzi, xa ibeka i-wiring, kungcono ukuba ithathe indawo ethile kwicandelo lengcinezelo. Okokuqala, necandelo elikhulu lomnqamlezo, umqhubi uya kufakwa kubushushu, okuthetha ukurhafa. Okwesibini, ezinye izixhobo ezisebenza ukusuka kumbane zivele ebomini bethu. Kwaye akukho mntu unokukunika isiqinisekiso sokuba kwiminyaka embalwa awudingi ukuba ubeke izixhobo ezitsha ezimbalwa ukongeza kwindala. Ukuba kukho isitokhwe kukho, banokuvula nje. Ukuba akunjalo, kuya kufuneka ube nobulumko-okanye utshintshe i-wiring (kwakhona) okanye uqinisekise ukuba akukho zixhobo zombane ezinamandla ngaxeshanye zine-ting ngaxeshanye.
Vula kwaye uvaliwe ucingo lokulala
Indlela Sonke sazi ngayo, xa sidlula kumqhubi wesifundo, siyakhaba. Inkulu yangoku, ubushushu obungakumbi babelaliwe. Kodwa, xa udlulisa okwangoku, ngokuqeqesha, enenani elahlukileyo, inani lamanqanaba akhutshiweyo: Inqanaba elincinci lecandelo, ukukhululwa kobushushu.
Kule meko, ngokuvulwa kwabaqhubi abavulekileyo, icandelo layo lomnqamlezo linokungaphantsi - lupholile ngokukhawuleza, njengoko kudlulisiwe ubushushu. Kwangelo xesha, umqhubi wesifundo uyaphola ngokukhawuleza, i-fanser ayizukuphazamisa. Nge-Like ilele, imeko imbi kakhulu - ishushu icotha enkosi. Ke ngoko, kwi-gasket evaliweyo-kwintambo yendlela, imibhobho, eludongeni - isicebisa ukuthatha intambo yecandelo elikhulu lomnqamlezo.
Ukukhethwa kwecandelo lentambo, kuthathelwa ingqalelo uhlobo lwe-gasket yayo, inokwenziwa usebenzisa itafile. Umgaqo wachazwa ngaphambili, akukho nto itshintsha. Thatha ingqalelo enye into.
Khetha icandelo lomnqamlezo kwi-Cable kuxhomekeke kumandla kunye nohlobo lwe-gasket
Kwaye ekugqibeleni, icebiso eliliqela elisebenzayo. Ukuya kwintengiso ngasemva kwentambo, thatha i-caliper kunye nawe. Rhoqo, icandelo elingumnqamlezo elibhengeziweyo alihambelani nenyani. Umahluko unokuba kwi-30-40%, kwaye oku kuninzi. Yintoni esongela ntoni? Ngokutshisa i-wiring ngayo yonke imiphumo elandelayo. Ke ngoko, kungcono ukukhangela ukuba le ntambo iyinyani le meko ifunekayo (i-Diameters kunye necandelo leCable elihambelanayo kwitheyibhile engentla). Funda ngakumbi malunga nenkcazo yecandelo Intambo ye-seameti yayo inokufundwa apha.
