Icandelo le-Wire cross-wiring

Umbane uye wagxininiswa kakhulu ebomini bethu kangangokuthi ukuxothwa kwamandla kagesi ngokukhawuleza kubonakala ngathi kuphephe, kwaye sikulindele ukuba kubuyiselwe. Sizungezwe inombolo enkulu yamandla kagesi ahlukeneyo adibanisa nenethwekhi yasekhaya ngokuthe ngqo kwiisiseko, okanye ngokusebenzisa Izandiso zokunyusa okanye ukuthwala.

Ngamanye amaxesha kuyimfuneko ukukhanyisa igaraji okanye esinye isakhiwo sezoqoqosho, uthathe indawo yocingo okanye wenze intambo yokongezwa ngokwenza. Okanye kufuneka ufumane ukuba yeyiphi na inombolo ephezulu yeefowuni ezinokufakwa ngexesha elilodwa ukwenzela ukuba lingashushu i-wire kwaye ibangela umlilo ngenxa yesiphaluka esifutshane. Kwiimeko ezinjalo, icandelo lecandelo kufuneka libalwe kwangaphambili ukuqinisekisa ukhuseleko lwefowuni efakwe.

Nguwuphi na ucingo endikukhethayo?

Ayikho imfihlo yokuba ubhedu buncinci obuchasene ne-aluminium, ngoko ke, ukuba uthelekisa iintambo zethusi kunye ne-aluminium kunye necandelo elifanayo le-wire cross-section, ngokokuqala kwimeko umthwalo ovumelekileyo uya kuba mkhulu. Intsimbi yobhedu inamandla, ilula kwaye ayiwaphuli kwiindawo zokuchithwa. Ukongezelela, ubhedu abukho ngaphantsi kwe-oxydation kunye ne-corrosion. Inzuzo kuphela yetambo ye-aluminium yindleko zayo, eziphindwe kathathu okanye ezine ngaphantsi kwebhesi enye.

Ukubalwa kwecandelo le-wire cross-section

Nayiphi na i-wiring yombane kufuneka ifane nomthwalo oxhunyiwe kuyo. Icandelo le-cross cross-count is calculated based on the maximum of the heat of the conductor. Inani lokushisa lixhomekeke kwindlela yamandla kagesi axhunyiwe. Ngaloo ndlela, ngokubala ubuninzi bezakhono ezipheleleyo zamagumbi kwigumbi, unokukwazi ukuba yeyiphi inxalenye yomgca wecala. Ngokwenza oko, kulungele ukusebenzisa i-calculator ye-intanethi okanye iitheyibhile ezizodwa eziqulethe ulwazi malunga nomthwalo okhoyo okhoyo kwikhebula.

Ungaqwalasela njani umgca wecala?

Ekubeni iingcingo zidla ngokuba nesimo se-circular cross-sectional, i-shear area ibalwa ngolu hlobo:

S = π ² d² / 4 okanye S = 0,8 х d², apho
Ummandla we-S-cross sectional of the vein in mm.kv;;
Π - 3,14;
D ububanzi bomda kwi mm.

Makhe sicinge, umzekelo, ukuba ububanzi bentambo ngu-1.3 mm., Emva koko S = 0.8 • 1.3² = 0.8 • 1.3 x 1.3 = 1.352 mm.kv.
Ukuba umnxeba unemizila emininzi, ke iqela lesiphambano lesinye senkalo libala kwaye landiswe ngenani labo lilonke kwisiqwenga. I-diameter ivame ukulinganiswa kunye nekaliper, kodwa ukuba ayikho, umlawuli oqhelekileyo uya kwenza. Kule meko, wongqinela ipensele malunga ne-10-15 ukujika, ulinganise ubude bomlawuli okhuphayo kwaye uhlule ixabiso elifunyenwe ngumbolo wokujika.

Ngayiphi na imisebenzi yokufakelwa kombane, kufuneka ukhumbule ukuba ngombane awukwazi ukunyamezela unyango obunyanisekileyo kwaye ungaxoleli iimpazamo. Ukukhuseleka kombane kunye nokuthembeka - yiloo nto ufanele uhlale ukulwela kuyo nayiphi na umsebenzi kunye nesekhaneli kagesi kwindlu, kwikhaya okanye endlwini.
