Kodi waya wokwera ndi chiyani?
Zamkatimu
Waya woyikirapo ndi kondakitala imodzi yokhala ndi insulated yoyenera kutsika kwamagetsi komanso kutsika kwapano. Chingwe cholumikizira chimagwira ntchito bwino m'malo otsekeka ndipo chimapezeka m'makonzedwe osiyanasiyana ndi ma conductor osiyanasiyana, kusungunula ndi zida za sheath.
Mu bukhuli, tiphunzira zambiri za waya wolumikizira ndi zomwe muyenera kuyang'ana mu waya wolumikizana wotetezeka:
Kodi chingwe cholumikizira chimagwiritsidwa ntchito chiyani?
Waya wolumikizira nthawi zambiri amagwiritsidwa ntchito pamagulu owongolera, magalimoto, mita, uvuni ndi makompyuta, zida zamagetsi, magalimoto amalonda ndi ma waya amkati amagetsi.
Waya wotsogolera amagwiritsidwa ntchito kwambiri pazida zamagetsi zomata, ngakhale mitundu ina ingagwiritsidwenso ntchito pakagwa zovuta zankhondo.
Mawaya ambiri olumikizira adavotera 600V; komabe, kutentha kumasiyana malinga ndi mapangidwe.
Kusankha waya woyenerera kuti mulumikizidwe
Kugula zingwe zigamba kungakhale ntchito yovuta poganizira zinthu zambiri.
Pogula mawaya olumikizira, ogula ayenera kuganizira izi:
Voteji
Pazifukwa zambiri ndikofunikira kusankha waya kapena chingwe choyenera pamagetsi ofunikira, zofunika zina ndi izi:
- Kuchuluka kwa waya kumakhudza kwambiri kukana; kukana kwakukulu kumatulutsa kutentha kwambiri; chifukwa chake, kuwunika kolakwika kwa waya kumatha kupangitsa kuti pakhale zovuta zachitetezo ndi moto.
- Mphamvu muwaya imatha kutsika pamtunda wautali; motero kusankha chingwe chomwe chimalepheretsa mwayi umenewu kapena kuonetsetsa kuti sichigwera pansi pa mlingo wovomerezeka ndikofunikira.
amperage
Izi ndi kuchuluka kwa mphamvu zomwe zimagwiritsidwa ntchito ndi chipangizo chamagetsi ndipo zimayesedwa mu ma amperes. Ndikofunikira kwambiri kudziwa kuchuluka kwa mawaya omwe angakokedwe ndi zida zonse posankha waya woti agwiritse ntchito. Ngati waya kapena chingwe chosankhidwa chili chochepa kusiyana ndi chofunikira pa dongosolo, mavuto monga kutentha kwambiri komanso kusungunuka kwa waya kumatha kuchitika.
kuchuluka ili ndi vuto lina pamene zipangizo zambiri zimagwirizanitsidwa ndi dera. Zikatere, makinawo sagwira ntchito moyenera chifukwa ophwanya madera amatha kugwa ndikuyimitsa chipangizocho.
waya gauge
American Wire Gauge (AWG) ndi mulingo wa mawaya amagetsi omwe amayesa mawaya opanda kanthu/odulidwa. Kutsika kwapakati kumakhala kofanana ndi kuchuluka kwa caliber.
Malo apamwamba, operekedwa mu mm2, ndi njira ina yoyezera makulidwe a waya. Pamene magetsi ochulukirapo akuyenera kunyamulidwa mozungulira, mawaya okulirapo amagwiritsidwa ntchito. Mawaya ataliatali amatha kugwiritsidwa ntchito mudongosolo chifukwa mawaya amayenda mosavuta kudzera pawaya popanda kukhazikika kwamagetsi.
Kutsegula
Kusungunula kuyenera kupirira mikhalidwe yosiyanasiyana, kuwonjezera pa kulekanitsa magetsi kuchokera kwa woyendetsa wina ndi kuyika pansi. Mfundo imodzi yofunika kuiganizira ndi kukhudzana ndi mankhwala ochokera ku chilengedwe. Kapangidwe ka insulation kamakhudza moyo wautumiki wa zinthu za Hardware.
Mawaya ambiri ndi insulated ndi zinthu ochiritsira PVC kuteteza kondakitala ku abrasion ndi mabwalo lalifupi. PVC ikhoza kusungunuka pansi pa kutentha kwakukulu. Pazifukwa izi, zida zoteteza mwamphamvu kwambiri monga fluorine kapena silikoni zimafunika.
Mawaya olumikizira amapezeka muzinthu zosiyanasiyana zotsekera monga PVC, PTFE, EPDM (ethylene propylene diene elastomer), hypalon, neoprene ndi rabara ya silikoni. (1)
Hook-Up waya ndi ubwino wake
Mawaya olumikizira amagwiritsidwa ntchito pazinthu zosiyanasiyana, zida ndi magalimoto. Nazi zina mwazabwino zogwiritsa ntchito mtundu uwu wa waya wamkuwa pantchito yanu:
- Waya wamkuwa ndi wokwera kwambiri kuposa zitsulo zonse.
- Waya wa Copper uli ndi kukana kwa dzimbiri chifukwa cha kutsika kwake, zomwe zimapangitsa kuti pakhale kufunikira kokwera mtengo m'malo mwa nthawi ndi nthawi.
- Mbali ina ya waya wolumikizira ndi kusinthasintha kwake, zomwe zikutanthauza kuti imatha kuumbidwa mosasunthika popanda kuphulika, zomwe zimathandiza kwambiri pamagetsi pomwe waya ayenera kukulunga pamakona. (2)
Onani zina mwazolemba zathu pansipa.
- Ndi waya uti womwe ukuchokera ku batire kupita koyambira
- Momwe mungalumikizire 2 amps ndi waya umodzi wamagetsi
- Momwe mungatsekere mawaya amagetsi
