1. Isingeniso
Ukukhetha indawo efanelekile ye-cross-sectional yekhebula lokushisela kubaluleke kakhulu kunalokho ongase ucabange. Ithinta ngqo ukusebenza komshini wakho wokushisela futhi iqinisekisa ukuphepha ngesikhathi sokusebenza. Izinto ezimbili eziyinhloko okufanele uzikhumbule lapho wenza ukukhetha kwakho inani lamanje ikhebula elingakwazi ukusibamba kanye nokwehla kwamandla kagesi ngobude bayo. Ukungazinaki lezi zici kungaholela ekushiseni ngokweqile, ekusebenzeni kabi, noma ngisho nokulimala okukhulu kwemishini.
Ake sihlukanise lokho odinga ukukwazi ngendlela elula, yesinyathelo nesinyathelo.
2. Izinto Ezibalulekile Okufanele Zicatshangelwe
Lapho ukhetha ikhebula lokushisela, kunezici ezimbili ezibalulekile:
- Amandla amanje:
- Lokhu kubhekisela ekutheni ikhebula likwazi ukuthwala ikhebula elingakanani ngaphandle kokushisisa ngokweqile. Ubukhulu bekhebula (indawo ephambanayo) bunquma ubukhulu bayo.
- Kuzintambo ezimfishane kunamamitha angu-20, ungakwazi ukugxila ku-ampacity kuphela, njengoba ukwehla kwamandla kagesi kungeke kubaluleke.
- Izintambo ezinde, nokho, zidinga ukunakwa ngokucophelela ngoba ukumelana nekhebula kungaholela ekwehleni kwe-voltage, okuthinta ukusebenza kahle kwe-weld yakho.
- Ukwehla kwamandla kagesi:
- Ukwehla kwamandla kagesi kubaluleka uma ubude bekhebula budlula amamitha angu-20. Uma ikhebula lincane kakhulu ukuze likwazi ukuthwala okwamanje, ukulahleka kwe-voltage kuyanda, kunciphisa amandla alethwa emshinini wokushisela.
- Njengomthetho wesithupha, ukwehla kwamandla kagesi akufanele kudlule i-4V. Ngalé kwamamitha angu-50, uzodinga ukulungisa isibalo futhi mhlawumbe ukhethe ikhebula eliwugqinsi ukuze uhlangabezane nezidingo.
3. Ukubalwa kwe-Cross-Section
Ake sibheke isibonelo ukuze sibone ukuthi lokhu kusebenza kanjani:
- Ake sithi i-welding current yakho300A, kanye nesilinganiso sobude besikhathi sokulayisha (umshini usebenza kaningi kangakanani).60%. I-current esebenzayo ibalwa njenge:
300A×60%=234A
- Uma usebenza ngokuminyana kwamanje kwe7A/mm², uzodinga ikhebuli enendawo ephambanayo ethi:
234A÷7A/mm2=33.4mm2
- Ngokusekelwe kulo mphumela, ukufana okuhle kakhulu kungaba aIkhebuli eguquguqukayo yerabha engu-YHH-35, enendawo ephambanayo engu-35mm².
Le khebuli izophatha yamanje ngaphandle kokushisisa ngokweqile futhi isebenze kahle ngaphezu kobude obungafika kumamitha angu-20.
4. Uhlolojikelele lwekhebula lokushisela le-YHH
Iyini ikhebula ye-YHH?Izintambo zokushisela ze-YHH zenzelwe ngqo ukuxhuma ohlangothini lwesibili emishinini yokushisela. Lezi zintambo ziqinile, ziyagobeka, futhi zilungele izimo ezinzima zokushisela.
- I-Voltage Compatibility: Bangakwazi ukusingatha ama-voltage aphezulu we-AC kuze kufike200Vkanye nama-voltage aphezulu e-DC afinyelela phezulu400V.
- Izinga Lokushisa Lokusebenza: Izinga lokushisa eliphezulu lokusebenza60°C, ukuqinisekisa ukusebenza okuthembekile ngisho nangaphansi kokusetshenziswa okuqhubekayo.
Kungani izintambo ze-YHH?Isakhiwo esiyingqayizivele samakhebula e-YHH siwenza aguquguquke, aphathe kalula, futhi amelane nokugqokwa nokudabuka. Lezi zakhiwo zibalulekile ezinhlelweni zokushisela lapho ukunyakaza okuvamile kanye nezikhala eziqinile zivamile.
5. Ithebula Lokucaciswa Kwekhebula
Ngezansi kunethebula lokucaciswa kwezintambo ze-YHH. Igqamisa amapharamitha angukhiye, okuhlanganisa usayizi wekhebula, indawo elinganayo enqamula izingxenye ezithile, kanye nokumelana ne-conductor.
Usayizi Wekhebula (AWG) | Usayizi Olinganayo (mm²) | Usayizi Wekhebula Lomgogodla Owodwa (mm) | Ubukhulu bomgodla (mm) | Ububanzi (mm) | Ukumelana Komqhubi (Ω/km) |
---|---|---|---|---|---|
7 | 10 | 322/0.20 | 1.8 | 7.5 | 9.7 |
5 | 16 | 513/0.20 | 2.0 | 9.2 | 11.5 |
3 | 25 | 798/0.20 | 2.0 | 10.5 | 13 |
2 | 35 | 1121/0.20 | 2.0 | 11.5 | 14.5 |
1/00 | 50 | 1596/0.20 | 2.2 | 13.5 | 17 |
2/00 | 70 | 2214/0.20 | 2.4 | 15.0 | 19.5 |
3/00 | 95 | 2997/0.20 | 2.6 | 17.0 | 22 |
Leli tafula lisitshelani?
- I-AWG (American Wire Gauge): Izinombolo ezincane zisho izintambo ezinkulu.
- Usayizi Olinganayo: Ibonisa indawo ephambanayo ku-mm².
- Ukumelana Komqhubi: Ukumelana okuphansi kusho ukwehla kwe-voltage encane.
6. Imihlahlandlela Esebenzayo Yokukhetha
Nalu uhlu lokuhlola olusheshayo lokukusiza ukuthi ukhethe ikhebuli efanele:
- Linganisa ubude bekhebuli yakho yokushisela.
- Nquma inani eliphezulu lamanje elizosetshenziswa umshini wakho wokushisela.
- Cabangela isilinganiso sobude besikhathi sokulayisha (umshini usebenza kaningi kangakanani).
- Bheka ukwehla kwamandla kagesi ukuze uthole izintambo ezinde (ngaphezu kuka-20m noma 50m).
- Sebenzisa ithebula lezicaciso ukuze uthole okufanayo okuhamba phambili ngokusekelwe ekumineni kwamanje nosayizi.
Uma ungabaza, kuhlala kuphephile ukuhamba nekhebula elikhudlwana. Ikhebula eliwugqinsi lingabiza kancane, kodwa lizohlinzeka ngokusebenza okungcono futhi lihlale isikhathi eside.
7. Isiphetho
Ukukhetha intambo yokushisela efanele imayelana nokulinganisa umthamo wamanje kanye nokwehla kwamandla kagesi kuyilapho ukhumbula ukuphepha nokusebenza kahle. Kungakhathaliseki ukuthi usebenzisa ikhebuli engu-10mm² ngemisebenzi elula noma ikhebuli engu-95mm² ezinhlelweni zokusebenza ezisindayo, qiniseka ukufanisa ikhebuli nezidingo zakho ezithile. Futhi ungakhohlwa ukubonana namathebula emininingwane ukuze uthole isiqondiso esinembile.
Uma ungaqiniseki, ungangabazi ukuxhumana nayeDanyang Winpowerabakhiqizi bezintambo—sikhona ukuze sikusize uthole okufanela kahle!
