Iwugqinsi kangakanani i-18 gauge wire?
Kubaluleke kakhulu ukwazi igeji yocingo lwakho lukagesi. Ukusebenzisa intambo yosayizi ongalungile ukuze unikeze amandla kagesi kungaba yingozi. I-18 gauge wire inesilinganiso samanje esingu-10-16 amps. Isetshenziswa kuma-circuits aphansi-voltage njengezinto zokukhanyisa - 10 amperes.
Ungabuthola kanjani ubukhulu be-18 gauge wire? Ungahlola isilinganiso se-ampere noma ubukhulu bangempela be-ampere obukhonjiswe kukhava yokufaka. Izintambo ezingu-18 zingu-0.048 amayintshi ubukhulu. Lokhu kungaguqulelwa ku-1.024 mm. Futhi inani eliphakeme lama-watts izintambo eziyi-18 gauge ezingaphathwa ngama-watts angama-600. Ungasebenzisa futhi I-NEC Wire Thickness Calculator ukubala ugqinsi lwezintambo eziyi-18 gauge.
Kulo mhlahlandlela, sizohlinzeka ngamathebula namashadi ukukusiza uhlole ukujiya kwezintambo. Sizophinde sichaze futhi sifanekise isibali sokujiya kocingo.
Ugqinsi lwentambo engu-18 gauge
Njengoba ngisanda kusho, izintambo eziyi-18 gauge ziwu-1.024 mm (0.048 amayintshi) ubukhulu. Zinesilinganiso samanje esingu-16 amps. Nokho, ubude bocingo buphinde buthinte isilinganiso se-ampere. Izintambo eziyi-18 gauge zingakwazi ukuphatha ama-amps angu-16 ngocingo oluyi-12". Kubalulekile ukuqaphela ukuthi ukusetshenziswa kwezintambo ezinkulu kwandisa amandla amanje. Lokhu kungenxa yokuthi i-gauge yocingo iyashintsha ngokulingana nobukhulu.
Ngincoma ukuthi usebenzise i-gauge wire enkulu ezimpahleni zokukhanyisa namanye amasekhethi kagesi ekhaya lakho. Izintambo zegeji ezinkulu zifaka isandla ekufakweni kwezintambo ezifanele zendlu ngoba ziyakwazi ukuphatha izilinganiso eziphezulu ze-amperage. Izintambo ezincane zingashisa kakhulu futhi kulokhu ziholela ekushayweni kukagesi.
Inombolo yama-watts intambo yegeji engu-18 engakwazi ukuyiphatha ngama-watts angu-600 (ebizwa nangokuthi amandla, inani lamanje elingathwalwa yintambo yegeji). Izilinganiso zamanje zegeji engu-18 nezinye izikali zezintambo ziboniswa kuthebula elingezansi.
Ithebula lokujiya kocingo
Kuhlelo lwe-AWG - American Wire Gauge, ubukhulu nobubanzi begeji yocingo kubalwa ngefomula:
Kusukela kufomula, singaphetha ngokuthi kuwo wonke amageji ayisithupha ububanzi bocingo buphindwe kabili. Futhi kuwo wonke ama-caliber amathathu, indawo ye-cross-sectional (CA) nayo iphinda kabili. I-Metric AWG wire gauge iboniswa kuthebula elingezansi.
I-Wire Thickness Calculator
Vula ngoba Isibali sokuqina kwentambo.
Isibali sokuqina kocingo sizokusiza ukubala ukujiya kocingo. Konke okudingeka ukwenze ukufaka amanani bese ukhetha uhlobo locingo - isibonelo, ithusi noma i-aluminium. Isibali sokuqina kwezintambo sizokunikeza imiphumela enembile ukukusiza ukuxazulula izinkinga ezihlobene nokubala ukujiya kwezintambo. (1)
Izici ze-Wire Gauge Calculator
- Umthombo wamandla kagesi - lapha ungakhetha i-voltage yomthombo - 120, 240 no-480 volts.
- Inombolo yezigaba - ngokuvamile isigaba esisodwa noma isigaba sesithathu. Amasekhethi esigaba esisodwa adinga ama-conductor angu-3, kanti amasekhethi ezigaba ezintathu adinga ama-conductor angu-3. I-NEC inquma ukushuba kwamakhondatha.
- Amps - Okwamanje okudonswe emthwalweni kuhlinzekwa ngumkhiqizi wemishini. Enye yezidingo ze-NEC ukuthi kumasekhethi esigaba esisodwa, lamanje kufanele libe izikhathi ezingu-1.25 kunomthwalo wamanje.
- I-voltage evumelekile ukuwa, AED - ungafaka i-AVD emshinini wokubala futhi uthole ugqinsi lwezintambo eziyi-18.
Isexwayiso: Kufanele ulandele imihlahlandlela ye-NEC lapho usebenzisa isibali ukuze uthole imiphumela emihle.
Bheka ezinye zezihloko zethu ngezansi.
