Kapangidwe
Chingwe cholumikizidwa ndi mtanda chimapangidwa ndi sheath yakunja, zida zachitsulo, sheath yamkati, zodzaza, zotchingira zamkuwa, wosanjikiza wakunja wa semiconducting, wosanjikiza wotsekereza, wosanjikiza wamkati wa semiconducting, conductor, core ndalama ya chingwe.Chifukwa chake, ndi mtundu wanji wa chingwe chomwe chiyenera kukhala ndi mtundu wanji wazinthu ndi ukadaulo wazowonjezera chingwe ndi makalata ake amodzi ndi amodzi.
Mfundo yopangira chingwe cholumikizira chingwe iyenera kukwaniritsa ndikukwaniritsa zofunikira: pangani chingwecho kuti chiyende bwino m'malo aliwonse achilengedwe.Kuti zimenezi zitheke, m’pofunika kumvetsera zinthu zinayi zofunika kwambiri, zomwe ndi: (1) kusindikiza, (2) kutsekereza, (3) malo amagetsi, (4) ndondomeko ndi zinthu zina.Izi ndikuthetsanso mavuto anayi ofunikira a mutu wa chingwe.
Osindikizidwa
1) Chifukwa zambiri zolumikizira zingwe zimayikidwa mumizere yakunja, mobisa ndi malo ena.Chifukwa chake, kutsekereza madzi ndi kutsimikizira chinyezi kwakhala imodzi mwamafungulo owonetsetsa kuti zingwe zolumikizira zingwe zikuyenda bwino.Ndipo ntchito yake yosindikiza ndi njira ziyenera kuganiziridwanso.
Pakalipano, pali njira ziwiri zosindikizira:
1. imodzi ndi njira yopangira miphika ndi phula kapena epoxy resin.Njirayi ndi yovuta pokonzekera, yovuta kulamulira, komanso yosagwirizana ndi kukonza.
2. Njira ina yatsopano, yomwe panopa ndi njira yokondedwa ya opanga akatswiri apakhomo ndi akunja, ndiyo kugwiritsa ntchito zosindikizira zotanuka kwambiri.Njirayi ndi yophweka, ntchitoyo ndi yodalirika, ndipo kukonza ndi kuyika ndizosavuta.Ubwino wapaderawu umapangitsanso kuti ikhale yogwiritsidwa ntchito kwambiri.
Kuti mugwiritse ntchito njira yatsopanoyi, chinthu choyamba choyenera kuganizira ndikuchita kwa sealant.Chifukwa khalidwe ndi ntchito ya sealant zimakhudza mwachindunji ntchito yosindikiza ya chingwe cholumikizira.Sankhani guluu lomwe lingagwirizane ndi pamwamba pa chingwe cha thupi ndi pamwamba pa zinthu zowonjezera mwamphamvu kwambiri.Panthawi imodzimodziyo, ndizofunikira kwambiri kuti muthe kukumana ndi guluu lomwe lingagwiritsidwe ntchito m'malo osiyanasiyana osintha kutentha.
2) Chifukwa zida zamagetsi zomwe zimatha kuzizira kwambiri ndizowonjezera chingwe chotanuka.Ndiko kunena kuti, elasticity ya mphira wamadzimadzi silikoni amagwiritsidwa ntchito kukulitsa pulasitiki ndi zingwe zothandizira mu fakitale pasadakhale.Ikhazikitseni pamalo omwe mwasankhidwa pomwepo, ndikutulutsa chothandizira kuti muchepetse mwachilengedwe.Ukadaulo wamtunduwu ndiukadaulo wocheperako, ndipo chowonjezera chamtunduwu ndi chowonjezera cha chingwe chozizira.Chifukwa chake, chowonjezera chozizira chozizirachi chimakhala ndi "kukhazikika" kwabwino.Ikhoza kupeŵa kuwonjezereka kwa kutentha ndi kutsika kwa chingwe chifukwa cha chilengedwe chamlengalenga ndi mlingo wa katundu panthawi yogwiritsira ntchito chingwe.Ndi ngozi yowonongeka chifukwa cha kusiyana pakati pa kutsekemera kopangidwa ndi "kupuma kwa chingwe".Choyipa chachikulu cha zida zowotcha kutentha ndikuti sizisintha.Chifukwa chake, zida zoziziritsa kuzizira kwathunthu ndizosankha zabwino kwambiri zogwiritsidwa ntchito m'malo omwe ali ndi kutentha kwakukulu komanso kukhudzidwa kwakukulu ndi chilengedwe.
Insulation
Chofunikira chachitetezo cha mutu wa chingwe ndikukwaniritsa zotchingira ziwiri zazikuluzikulu za gawo ndi gawo ndi malo otsutsana.
1. Kutsekemera kwa gawo-to-phase ndi mitundu iwiri ya zipangizo zotetezera: mtundu wa mphira wa silicone ndi zinthu zomwe zimatha kutentha.Nthawi zambiri, ntchito yotchinjiriza imayenera kukwaniritsa zofunikira potengera index insulation ya unit yazinthu kuphatikiza makulidwe azinthuzo.
2. Kusungunula pakati pa gawo mpaka pansi ndikuteteza kuti chiwongola dzanja chisakwere mtunda wotetezeka kuchokera kumtunda wapamwamba kupita kumalo otsika.Zida za rabara za silicone zoziziritsa kuzizira zimakhala ndi zotanuka bwino.Malingana ngati mapangidwewo ndi omveka, kukhazikika kwake kolimba kumakhala ndi mphamvu zokwanira.The shrinkage kutentha kwa kutentha shrinkable chingwe mutu ndi 100 ℃-140 ℃, ndipo kutentha akhoza kukumana shrinkage mikhalidwe yake shrinkage kokha atayikidwa.Kutentha kukakhala kotsika, chifukwa chowonjezera kutentha kwa chingwecho ndi chosiyana ndi cha zinthu zomwe zimatha kutentha, ndizotheka kuti delamination ichitike m'malo osakwana 80 ℃, kotero ming'alu idzawonekera.Mwa njira iyi, madzi ndi chinyezi zidzalowa pansi pa kupuma, potero kuwononga kutsekemera kwa dongosolo.Komabe, pamene chilengedwe chimasintha, palibe kusungunuka ngati mphira wa silicone, kotero zidzakhudzanso chitetezo.Izi ndi kuipa kwa kutentha shrinkable zipangizo.
Zamagetsi
Gawo lamagetsi lazingwe zoziziritsa kuzizira zimathandizidwa ndi njira ya geometric, yomwe imasintha kugawa kwamagetsi kudzera mu cone yopsinjika.Imathetsedwa ndi mawonekedwe ena a geometric ndi ngodya yolondola ya R.Njirayi ndiyosavuta kuwongolera ndikuyesa.Ikhoza kutsimikiziridwa ndikuzindikira mufakitale.Njira yamagetsi yamagetsi yamutu wa chingwe chowotcha kutentha ndikusintha magawo amagetsi amagetsi ndi njira yofananira.Iyenera kudalira magawo awiri ofunikira: kukana kwa voliyumu, 108-11Ω, ndi b dielectric yokhazikika ya 25. Chifukwa cha zovuta zake zopangira komanso kusintha kwakukulu chifukwa cha chilengedwe, n'zovuta kulamulira kukhazikika kwa magawo.Choncho, zidzakhala ndi zotsatira pa khalidwe la mankhwala.
Kusankha njira yabwino kwambiri yoyimitsira chingwe kapena zolumikizira pulojekiti sikuyenera kuganiziridwa.Kuyimitsa chingwe chanu posachedwa kudzakhala gawo lalikulu la ntchito yanu.Simungathe kulipira gawo labizinesi yomwe yatsekedwa chifukwa chokonzedwa pafupipafupi kapena kusokonekera.Kutsika kozizira koyenera / kutentha kutsika kwazinthu zoyimitsa chingwe kumakulitsa zokolola zanu ndikupangitsa kuti ntchito ikhale yosavuta kwa antchito.Ingotsimikizirani kuti mwachita kafukufuku woyenera kuti musankhe kuyimitsa chingwe komwe kumagwira ntchito zanu zonse, kumapereka ntchito yodalirika, ndipo antchito anu amaphunzitsidwa bwino.
