Ibanga eliphakeme elimelana nokushisa okungenasici enamelled multi-strand bare copper wire evalwe ngocingo ukushaja okusheshayo kokuphakelwa kukagesi ezimotweni zamandla ezimoto

1, Isakhiwo kanye nempahla

1. Intambo enemicu: ebizwa nangokuthi intambo enemicu eminingi, ibhekisela ekuxhumekeni okugxilile kwezintambo eziningi zocingo olulodwa olunoqweqwe oluqinile lokucaciswa okufanayo, futhi isiqondiso sokuxhuma sesendlalelo ngasinye sihlehliswa ngokushintshana.

2. Ubude be-strand: isilinganiso sesethi yebanga elisebenzayo lokulinganisa nenani lokujika elijikayo ubude be-twist (iphimbo) locingo oluboshwe.

3. Inani lamasheya: njengoba kucaciswe ikhasimende;

4. Indlela yokusonta: ibhekisela ekuthatheni indawo enqubweni yokukhiqiza, evame ukuhlukaniswa ibe iphozithivu (S), okungukuthi isiqondiso sewashi, nokuhlehla (Z), okungukuthi isiqondiso esiphambene newashi.

2. Izinga lohlelo lokusebenza

Bheka ku-IEC JIS GB kanye namanye amazinga ocingo olunameyili

3. Ukucaciswa kokuhlolwa

1. Izidingo zokubukeka: ukubukeka okubonakalayo kuyacwebezela, ngaphandle kokulimala komshini kungqimba kapende, akulula ukukhuhla ifilimu kapende ngezinzipho, alukho ucingo olusontekile oluxekethile, ukugxuma nezinye izenzakalo, futhi izintambo zihlanzekile futhi zizinhle.

2. Imfuneko yobude be-twist: thatha isampula engu-500mm, shiya isibonelelo esingu-100mm kuzo zombili iziphetho zesampula engu-500mm, thatha umucu wocingo olunwetshiwe kusukela ekuqaleni ukuze uxege, futhi kancane kancane uxegise inani lokujika ukusuka ekugcineni ukuya ekugcineni kuka-b, bese urekhoda isilinganiso senani lokujika ukuya ebangeni elilinganisiwe. Inani elitholiwe ubude be-twist lwentambo enoqweqwe oluqinile, ithatha indawo yedesimali eyodwa, futhi ukubekezelela okuvamile kungu-± 1mm.

3. Indlela yokubala yobubanzi obungaphandle obuqediwe bocingo oluyintambo Z: D=1.155 ×√ N × d

D=intambo enentambo Z enkulu enobubanzi be-coefficient=1.155 N=inani lezintambo zocingo oluyintambo d=intambo enoqweqwe olulodwa Z elikhulu eliqediwe elingu-coefficient wangaphandle=1.155

Le fomula yokubala ingasetshenziswa kuphela njengereferensi.

4. Ukuhlolwa kwamandla kagesi okuqhekeka kwentambo ene-enamelled: phinda isampula ngayinye ngobude obungu-500MM phakathi bese uyisonta ngokuvumelana nelungiselelo elikuThebula 1. Ngemva kokusonta, sika iziphetho zesampula bese ushiya ubude obuphakathi bungu-120MM. Ukuphela kocingo kuhlukaniswe kabili ngokusho kwenani lezintambo. Omunye umkhawulo usesimweni sesifunda esivulekile, kanti omunye ucwiliswa ethini njengokuphela kokulinganisa. Bopha enye yezingxenye zokucwilisa ithini nge-electrode ephozithivu futhi enye nge-electrode eyinegethivu, bese uvula iswishi yensimbi ukuze ihlolwe. Umgomo uwukuphakamisa ngokulinganayo i-voltage kuze kube yilapho ifilimu kapende yesampula iphuka. Ngalesi sikhathi, inani eliboniswa ensimbini yinani le-voltage yesampula.

5. Intambo evalekile evalekile yenziwe ngocingo olunamalitha olunemicu eminingi ngokusebenzisa intambo yomshini, futhi i-voltage yayo izonqunywa ngokwenani lezintambo. Izinga le-voltage lizokwehliswa njengoba inani lezintambo likhula. Ukuze uthole imininingwane, phindaphinda isilinganiso ngokwezinga locingo olunamele. Bheka ku-(JISC3202-1994).

5.1 Uma inani lezintambo (N) lingaphansi kwama-20, i-voltage ehlukanayo yocingo oluboshiwe ingu-V=ivoltheji yokuphuka yocingo olulodwa olungenantambo * 90%.

5.2 Uma inani lezintambo lingu-20 ≤ N ＜ 60, i-voltage yokuphuka yocingo oluboshiwe V=i-voltage yokuphuka yocingo olulodwa olunameli * 80%.

5.3 Uma inombolo yezintambo ingu-60 ≤ N ＜ 120, i-voltage yokuhlukana yocingo oluboshiwe V=i-voltage yokuphuka yocingo olulodwa olunameyili * 70%.

5.4 Uma inombolo yezintambo ingu-N ≥ 120, i-voltage ehlukanayo yocingo oluboshiwe V=ivoltheji yokuphuka yocingo olulodwa olunameli * 60%.
