Anthu ambiri samamvetsetsa kugwirizana pakati pa wire gauge ndi capacitance. Wina angaganize kuti mawaya a 18-gauge angagwiritsidwe ntchito mdera lililonse, koma sizili choncho. Mphamvu yamagetsi ikasintha, mtengo wapamwamba wa waya womwewo umasintha. Mofananamo, sitingathe kunyalanyaza kutalika kwa waya ndi mphamvu yake. Ndakumanapo ndi izi pazantchito zambiri zamagetsi. Chifukwa chake lero ndikhala ndikungoyang'ana pakutha ndikukambirana za ma amps 18 mawaya angati omwe angagwire.
Nthawi zambiri, mawaya a geji 18 amatha kugwira ma amps 14 pa 90 ° C. Uwu ndiye mulingo womwe umatsatiridwa ndi akatswiri ambiri amagetsi. Komabe, malingana ndi mtunda ndi magetsi, mtengo womwe uli pamwambawu ukhoza kusintha.
Ndi ma amps angati omwe 18 AWG angagwire?
AWG imayimira American Wire Gauge. Iyi ndiye njira yoyezera mawaya ku North America.
Waya wamkuwa wa 18 AWG umapirira ma amps 14 pa 90°C. Nthawi zambiri 18 AWG imakhala ndi waya awiri a 1.024 mm2 ndi gawo lapakati la 0.823 mm2.
The matalikidwe zimadalira zinthu zosiyanasiyana monga non-reactivity, voteji mlingo, kusinthasintha, kachulukidwe ndi flammability. Komabe, kutentha kungatchedwe chinthu chofunika kwambiri. Pamene kutentha kuli kwakukulu, mphamvu yoyesedwa imawonjezeka.
Ndicho chifukwa chake akatswiri ambiri amalemba kutentha kwapadera ndi kukula kwa waya. Mu chithunzi pamwambapa, mungapeze mawaya amitundu yosiyanasiyana omwe ali oyenera kutentha ndi mtunda wina.
Ndi ma amps angati omwe angagwire waya wa 18 geji pa 12 volts?
Monga ndanenera kale, amperage imasiyanasiyana ndi magetsi ndi kutalika kwa waya. Chifukwa chake mukayika 12V, yapano imasiyana kuchokera ku 0.25A mpaka 10A kutengera mtunda. Kutsika kwa magetsi ndicho chifukwa chachikulu cha kusinthaku.
Voteji dontho
Nthawi zonse kukana kwa waya kumawonjezeka, kutsika kwamagetsi kumawonjezeka moyenerera. Ngati mukuvutika kumvetsa mfundo yomwe ili pamwambayi, kufotokoza kumeneku kungakuthandizeni.
Kukaniza kumadalira malo ozungulira ndi kutalika kwa waya. Tsatirani equation pansipa.
Apa R ndi kukana. ρ ndi resistivity (mtengo wokhazikika). A ndiye gawo la waya ndipo L ndiye kutalika kwa waya.
Choncho, pamene kutalika kwa 18-waya gauge kumawonjezeka, kukana kumawonjezeka moyenerera.
Malinga ndi lamulo la Ohm,
V ndi voteji, ine ndi yapano, ndipo R ndi kukana.
Chifukwa chake, pakukana kwakukulu, kutsika kwamagetsi kumawonjezeka.
Kutsika kwamagetsi kovomerezeka
Kutsika kwamagetsi kovomerezeka kuyenera kukhala kosachepera 3% pakuwunikira ndi 5% pazida zina zamagetsi.
Poganizira kutsika kwamagetsi, nazi zitsanzo za mawaya amkuwa a 12V ndi 18 geji.
Mwachitsanzo 1
Monga mukuonera, ngati panopa ndi 5 amps, mukhoza kuthamanga 18 gauge waya 5 mapazi.
Mwachitsanzo 2
Monga mukuonera, ngati panopa ndi 10 amps, muyenera kuthamanga 18 gauge waya zosakwana 3 mapazi kutali.
Tsatirani ulalo uwu wa chowerengera chotsitsa ma voltage.
Ndi ma amps angati omwe angagwire waya wa 18 geji pa 24 volts?
Mphamvu yamagetsi ikakhala 24 volts, waya wa 18 gauge amatha kugwira ntchito kuyambira 10 VA mpaka 50 VA. Monga m'zitsanzo pamwambapa, mfundo izi zili ndi mtunda wosiyana.
Mwachitsanzo 1
Monga mukuonera, ngati panopa ndi 5 amps, mukhoza kuthamanga 18 gauge waya 10 mapazi.
Mwachitsanzo 2
Monga mukuonera, ngati panopa ndi 10 amps, muyenera kuthamanga 18 gauge waya 5 mapazi.
Ndi ma amps angati omwe angagwire waya wa 18 geji pa 120 volts?
Pa 120 volts, 18 gauge waya imatha kunyamula ma amps 14 (1680 watts). Mutha kuthamanga 18 gauge waya 19 mapazi.
Kumbukirani: Apa timasunga kutsika kovomerezeka kwamagetsi pansi pa 3%.
Ndi ma amps angati omwe angagwire waya wa 18 geji pa 240 volts?
Pa 240 volts, 18 gauge waya imatha kunyamula ma amps 14 (3360 watts). Mutha kuyendetsa mawaya 18 mpaka 38 mapazi.
Kugwiritsa ntchito 18 gauge waya
Nthawi zambiri, mawaya a 18 gauge amatha kupezeka mu zingwe za nyale za 10A. Kuphatikiza apo, mutha kupeza mawaya a 18 gauge pazotsatira zotsatirazi.
- Waya wa 18 gauge ndi njira yabwino kwambiri yamabatire amgalimoto ndi zida zina zamagalimoto. Mwachitsanzo, mawaya ambiri oyankhula ndi 12 mpaka 18 geji.
- Anthu ena amagwiritsa ntchito waya wa 18 geji pazingwe zowonjezera. Mwachitsanzo, pazida zamagetsi monga zobowolera ndi zopukutira, mawaya 18 ojambulirawa ndi ofala.
Kodi 18 gauge waya adavotera chiyani?
Waya wa 18 AWG adavotera kuyatsa kwamagetsi otsika.
Kodi zinthu (aluminium / mkuwa) zimasintha amperage?
Inde, mtundu wa zinthu umakhudza mwachindunji amperage. Aluminiyamu ndi mkuwa ndizinthu zomwe zimagwiritsidwa ntchito popanga mawaya a AWG awa. Tisanadumphe m'mene ma conductor amasiyanirana ndi zinthu zamakono, nazi zina mwazinthu zapadera za makokitalawa.
Mkuwa
Pakati pazitsulo ziwiri zomwe tazitchula pamwambapa, opanga ambiri amagwiritsa ntchito mkuwa popanga mawaya. Mungapeze mawaya amkuwa mu zipangizo zamakono zogawa magetsi ndi zamagetsi. Pali zifukwa zambiri za kutchuka koteroko. Nazi zina mwa izo.
apamwamba conductivity
Chimodzi mwa zifukwa zazikulu za kutchuka koteroko ndi conductivity. Mkuwa uli ndi magetsi apamwamba kwambiri pakati pa zitsulo zopanda mtengo. Izi zikutanthauza kuti mkuwa ndi conductive kwambiri kuposa aluminiyamu.
Kuwonjezeka kwa kutentha kwapansi
Kuonjezera apo, coefficient yotsika yowonjezera kutentha ndi mwayi wogwiritsa ntchito mkuwa. Chifukwa cha izi, mkuwa susintha mosavuta ndi kusintha kwa kutentha.
Mwayi wopeza patina wobiriwira
Green patina ndi mankhwala omwe amapangidwa mwachilengedwe pa bronze ndi mkuwa. Mankhwalawa ndi osakaniza a sulfide, mkuwa wa chloride, carbonates ndi sulfates. Chifukwa cha wosanjikiza wobiriwira wa patina, mkuwa umakhala ndi kukana kwambiri kwa dzimbiri.
Langizo: Patina wobiriwira samakhudza makhalidwe a waya wamkuwa.
Aluminium
Aluminiyamu ndichitsulo chodziwika kwambiri poyerekeza ndi zingwe zamkuwa. Komabe, aluminiyamu ili ndi zinthu zina zapadera zomwe zingakhale zopindulitsa kwambiri. Nazi zina mwa izo.
Zochepa thupi
Ngakhale kuti aluminiyumu ali ndi 61 peresenti yocheperako kuposa mkuwa, aluminium ndi yofanana ndi 30 peresenti ya kulemera kwa mkuwa. Chifukwa cha izi, mawaya a aluminiyamu ndi osavuta kugwira.
Zotsika mtengo
Poyerekeza ndi mkuwa, aluminiyumu ndi yotsika mtengo kwambiri. Ngati mukuyang'ana pulojekiti yotsika mtengo yopangira magetsi, aluminiyamu iyenera kukhala chisankho chanu.
Kumbukirani: Aluminiyamu imakumana ndi madzi ndikutulutsa mpweya wa haidrojeni. Ili ndi vuto lalikulu pakati pa opanga. Sangagwiritse ntchito mawaya a aluminiyamu pa ntchito monga kuyala zingwe zapansi pamadzi. (1)
Nanga bwanji mphamvu zamakono?
Mwachitsanzo, ngati mukugwiritsa ntchito mawaya 8 a mkuwa pa ntchito yomwe mwapatsidwa, mudzafunika mawaya 6 a aluminiyamu pa ntchito yomweyo. Kumbukirani kuti ndi manambala apamwamba, makulidwe a waya amachepa. Chifukwa chake, mufunika waya wokhuthala wa aluminiyamu.
Ubwino womvetsetsa 18 gauge wire amps
Kudziwa ma amperage mawaya a 18 gauge kudzakuthandizani kusankha zamagetsi ndi ntchito zoyenera. Ndi makulidwe ang'onoang'ono, kukana kwa waya kumawonjezeka chifukwa cha malo ang'onoang'ono odutsa. Izi zikutanthauza kuti mawaya adzatentha ndipo pamapeto pake adzasungunuka. Kapena nthawi zina zimatha kukhudza zamagetsi anu. Chifukwa chake, kulumikizana ndi chingwe cholondola cha waya ndikofunikira. Osagwiritsa ntchito 18 gauge waya pamagawo opitilira 14 amps. (2)
Mafunso ofunsidwa kawirikawiri
Kodi mtunda umakhudza ma amps?
Inde. Pamene mtunda ukuwonjezeka, mtengo wa amplifier umachepa chifukwa cha kukana kwakukulu. Ichi ndichifukwa chake muyenera kuyendetsa mawaya pamlingo wovomerezeka wamagetsi.
Mawaya apamwamba kwambiri a 18 AWG?
Nthawi zambiri, waya wa 18 AWG amatha kugwira mpaka 16A. Koma mulingo woyenera ndi 14A. Chifukwa chake, sungani mtengo wa amplifier pamalo otetezeka.
Kodi mulingo wa ampere pawaya wa 18 gauge stranded ndi chiyani?
Waya wapakati pa 18 gauge ndi 14A. Komabe, mawaya olimba amatha kunyamula mphamvu zambiri kuposa mawaya omangika. Akatswiri ena atha kuchepetsa mawaya a 18 gauge mpaka 7A.
Kodi mulingo wa ampere wa waya wamagalimoto 18 ndi chiyani?
Mawaya agalimoto a 18 gauge ndi apadera. Mawayawa amatha kugwira ntchito kuchokera ku 3A mpaka 15A. Zikafika patali, mutha kuphimba kuchokera ku 2.4 mapazi mpaka 12.2 mapazi.
Kufotokozera mwachidule
Mosakayikira, waya wa 18 gauge ndi chisankho chabwino kwambiri pakuyika ma voltage otsika. Makamaka ngati mukugwiritsa ntchito mababu 10 amp, 18 gauge waya ndi yabwino kwa mababu awa.
Komabe, onetsetsani kuti mwachita homuweki musanapange chisankho chomaliza. Yang'anani mlingo wa kutsika kwa magetsi malinga ndi mtunda. Onaninso mtundu wa waya; zolimba kapena zopindika. Osagwiritsa ntchito waya wokhazikika m'malo mwa waya wolimba. Kulakwitsa kopusa kotereku kumatha kuwononga zamagetsi kapena kusungunula mawaya.
Onani zina mwazolemba zathu pansipa.
- Ndi ma watt angati omwe 16 angayesere pawaya wa sipika?
- Kodi kukula kwa waya kwa 20 amps 220v ndi chiyani?
- Komwe mungapeze waya wandiweyani wamkuwa wa zidutswa
