Kodi Ndikufunika Ma Ferrules a Waya pa Waya Wokhazikika mu Ma Control Panels?

Ngati mumanga kapena kusamalira ma control panels, mwina mwakhala mukufunsa funsoli kangapo: kodi waya wosweka ayenera kupita molunjika ku terminal, kapena ayenera kuyikidwa ferrule kaye? Yankho lalifupi ndilakuti ma ferrule amalimbikitsidwa kwambiri kwa ma stranded conductors, ndipo m'madera ambiri amafunikira kwambiri malinga ndi machitidwe a mawaya ndi miyezo yowunikira. Nayi chifukwa chake, komanso momwe mungasankhire ndikuyika ma crimp molondola.

Kodi ndi chiyani Chingwe cha waya kwenikweni amachita

Chingwe cha waya, chomwe chimatchedwanso chingwe cha bootlace kapena Chotsirizira cha chingwe, ndi chubu cha mkuwa chopangidwa ndi zitini, nthawi zambiri chokhala ndi kolala yotetezedwa ndi utoto, yomwe imakwinya kumapeto kwa kondakitala yosweka. Imasandutsa mtolo wosasunthika wa ulusi wopyapyala kukhala pini imodzi yolimba. Pini imeneyo imalowa bwino mu screw terminal, spring clamp, kapena push-in connector.

Ubwino wake ndi wamakina komanso wamagetsi nthawi imodzi. Zingwe zotayirira zimatuluka ngati screw yazimangirira. Zingwe zingapo zimatha kutuluka mu clamp kwathunthu, zomwe zimachepetsa malo ogwira ntchito a kondakitala ndikupanga malo otentha. Pakapita nthawi, screw yomwe imagwirira ntchito mwachindunji pa zingwe zofewa zamkuwa imamasukanso, ndipo kulumikizana kumamasuka. Ferrule imaletsa mavuto onse awiri: screw clamps imayika pini yolimba, kondakitala yonse imakhala mkati mwa terminal, ndipo mphamvu yolumikizira imakhala yokhazikika.

Kumene malamulo a ferru akufunika kapena kulangizidwa mwamphamvu

Mu ma panelo owongolera mafakitale omangidwa motsatira machitidwe apadziko lonse lapansi, ma ferrule omwe ali pa waya wosweka amaonedwa ngati ntchito yodziwika bwino. Oyang'anira ndi malangizo omangira ma panelo amaletsa kutsekereza ma kondakitala opanda kanthu omwe ali pansi pa sikulufu, chifukwa cha mavuto otsekereza ndi kumasula omwe afotokozedwa pamwambapa. Makamaka ma terminal a spring-clamp ndi push-in amapangidwa kuti alandire waya wolimba kapena kondakitala wokhala ndi ferrule; zingwe zopanda kanthu nthawi zambiri sizimayikidwa modalirika.

Pali nthawi zingapo pomwe ma ferrule safunikira. Ma conductor olimba safuna, chifukwa palibe zingwe zomasuka. Ma terminal ena amayesedwa mwachindunji kuti alumikizane mwachindunji ndi waya wolumikizidwa ndi chogwirira chomwe chimagwira zingwe zonse. Ngati mukukayika, yang'anani kuchuluka kwa wopanga ma terminal, koma pazifukwa zambiri zolumikizira zolumikizidwa mu panel, ferrule ndiye njira yotetezeka kwambiri.

Momwe mungakulitsire kukula kwa ferrule molondola

Ma ferrule amakula malinga ndi kutalika kwa kondakitala ndi kutalika kwa pini. Gawo lopingasa, lolembedwa mu mm2, liyenera kufanana ndi waya: kondakitala wa 1.5 mm2 amafunika ferrule wa 1.5 mm2, osati wa 2.5 mm2. Ferrule yayikulu kwambiri singathe kumangidwa mwamphamvu pa zingwe, zomwe zimalepheretsa cholingacho. Kutalika kwa pini kuyenera kufanana ndi kuya kwa terminal kotero kuti kolala yotetezedwa ikhale kunja kwa thupi la terminal ndipo palibe kondakitala wopanda kanthu yomwe imaonekera.

Kulemba mitundu kumapangitsa izi kukhala zofulumira kwambiri. Zambiri mwa izo ndi zachangu. Ferrule yotetezedwas amatsatira njira yodziwika bwino yolumikizirana ndi mitundu, kotero wopanga mapanelo amatha kusankha kukula koyenera malinga ndi mtundu: mwachitsanzo, mtundu winawake wa 0.5 mm2, wina wa 0.75 mm2, wina wa 1.0 mm2, ndi zina zotero. Kukhazikitsa dongosolo la mtundu umodzi m'sitolo yanu kumachepetsa zolakwika ndikufulumizitsa kusonkhana. Ma ferrule awiri, omwe amatenga ma conductor awiri mu kolala imodzi, amapezeka mukafuna kuyika mawaya awiri mu terminal imodzi.

Kudula tsitsi kumakhudza njira yoyenera

Chingwe chabwino cha ferrule chimakhala ndi sikweya, osati chosalala. Gwiritsani ntchito chida chopangira ferrule chokhala ndi die ya indent inayi kapena ya hexagonal. Zida zimenezi zimakanikiza chubu mofanana mbali zonse, zomwe zimapangitsa kuti chigwirizano cholimba chigwire ulusi ndikusunga mphamvu yolumikizana. Pewani ma pliers omwe amangophwanya ferrule mosalala; chingwe chosalala chimagwira mosagwirizana ndipo chimatha kuswa kolala yoteteza.

Kayendedwe ka ntchito ndi kosavuta. Chotsani kondakitala kuti kutalika kwake kugwirizane ndi mbiya ya ferrule, popanda mkuwa wotuluka pamwamba pa kolala ndipo palibe chomwe chimasiyidwa mkati mwake. Ikani kondakitala mokwanira, kenako pindani kamodzi ndi kukula kofanana kwa die. Mukamaliza kukanda, pini iyenera kukhala yolimba, zingwe siziyenera kusuntha, ndipo kolala iyenera kukhala yolimba. Kukoka mwachangu kumatsimikizira mgwirizano. Pa ntchito yayikulu, ratchet ferrule crimper yodzisinthira yokha imasunga mapeto onse ogwirizana popanda kusintha ma die pamanja.

Zolakwitsa zomwe anthu ambiri ayenera kupewa

Zolakwika zingapo zomwe zimachitika mobwerezabwereza sizithandiza kugwiritsa ntchito ma ferrule konse. Kuchotsa ma insulation ambiri kumasiya mkuwa wopanda kanthu ukuwonekera kupitirira kolala, zomwe ndi chiopsezo cha kugwedezeka komanso kufupika kwa magetsi. Kuchotsa pang'ono kwambiri kumatanthauza kuti kondakitala safika pansi pa mbiya, kotero crimp imagwira insulation m'malo mwa mkuwa. Kugwiritsa ntchito kukula kolakwika kwa ferrule kumapanga pini yomasuka kapena yopanikizika kwambiri. Ndipo kusakaniza mitundu ya ferrule ndi zida zosagwirizana kungapereke zotsatira zosagwirizana, kotero ndikofunikira kuyika muyezo pakuphatikizana kwa ferrule ndi zida zogwirizana.

Mfundo yofunika kwambiri

Pa waya wosweka m'mapanelo owongolera, ma ferrule si njira yosankha yosinthira; ndi muyezo wothandiza wa ma terminal otetezeka komanso olimba. Amasunga chingwe chilichonse chogwira, amakhala ndi mphamvu yokhazikika yolumikizira, ndipo amapatsa mapanelo anu mawonekedwe oyera komanso aukadaulo omwe amapambana mayeso. Gwirizanitsani gawo la ferrule ndi kondakitala, sankhani kutalika kwa pini komwe kukugwirizana ndi ma terminal anu, crimp ndi chida choyenera cha indent zinayi, ndikuyika mu mtundu umodzi pamakina onse ogulitsa. Ngati mukufuna thandizo popanga zida za ferrule zomwe zimaphimba kukula kwa kondakitala yanu yonse, gawani mndandanda wanu wa mawaya ndi mitundu ya ma terminal ndipo tidzapanga mitundu yosiyanasiyana ya ma ferrule ndi zida zokhoma.
