Kodi mukudziwa zambiri za zingwe zamagetsi zomwe zimagwiritsidwa ntchito kwambiri? (Gawo 3)

1. Phukusi la chingwe chowunikira Chingwe cholumikizira cha AD-Lash (All-Dielectric Tie-in) chopanda zitsulo komanso chingwe chowunikira cha wound chopanda zitsulo

Chingwe chowunikira cha GWWOP (GroundWireWrappedOpticalFiberCable) nthawi zina chimatchulidwa pamodzi chingwe cha fiber optic Kuphatikiza apo - OPAC, yomwe ndi njira yotsika mtengo komanso yachangu yopangira netiweki yolumikizirana ya fiber optic pamagetsi.
Amagwiritsa ntchito makina omangirira ndi opindika okha kuti amange ndi kukulunga zingwe za kuwala pa mawaya apansi kapena a gawo. Ubwino wawo wodziwika bwino ndi wakuti: zingwe za kuwala ndi zopepuka, zotsika mtengo, komanso zofulumira kuziyika. Zitha kuyikidwa pa waya wapansi kapena mzere wa gawo la 10kV/35kV popanda kusokoneza magetsi. Vuto lodziwika bwino ndilakuti, popeza zonse zimagwiritsa ntchito zinthu zopangidwa ndi organic ngati chivundikiro chakunja, sizingathe kupirira kutentha kwakukulu komwe kumapangidwa ndi waya wa gawo kapena wa pansi pamene mzerewo wafupikitsidwa. Kukalamba kwa zinthu zakunja kumafuna makina apadera panthawi yomanga, ndipo pali mavuto ambiri pankhani ya kuthekera ndi chitetezo cha zomangamanga. Amakhalanso pachiwopsezo cha kuwonongeka kwakunja, monga kugundana kwa mbalame, kuwombera mfuti, ndi zina zotero, kotero izi sizinathetsedwe mokwanira m'makina amagetsi. Ngakhale kuti pali mitundu yosiyanasiyana ya ntchito, ukadaulo wamtunduwu sunathetsedwe kapena kusiyidwa ndipo ukugwiritsidwabe ntchito m'njira zambiri padziko lonse lapansi.

2. Chingwe cha fiber optic composite

Chingwe cha fiber optic composite chikufanana kwambiri ndi OPPC. Chingwe cha fiber optic chimaphatikizidwa ndi chingwe, kotero chingwecho chili ndi ntchito ziwiri za mzere wa gawo ndi kulumikizana. Zingwe za fiber optic composite zimaphatikizapo zingwe za fiber optic composite za OPLC zotsika mphamvu, zingwe za OPMC zotsika mphamvu, ndi zingwe za fiber optic composite zamphamvu kwambiri, zomwe tsopano zimagwiritsidwa ntchito mu zingwe zamphamvu kwambiri (monga zingwe zamagetsi za sitima yapamadzi ya 110 kV, zingwe zamagetsi za sitima yapamadzi ya 220 kV, ndi zingwe zina zapansi).
Chingwe cha OPMC chapakati pa voltage ya fiber optic ndi chingwe chanzeru chapakati pa voltage yamagetsi chamagetsi chokhala ndi voltage yodziwika bwino ya 6 kV mpaka 35 kV. Chingwe chapakati cha fiber optic chopangidwa ndi magetsi chapakati ichi chimakhala ndi pakati pa chingwe, gawo la tepi yapakati, ndi jekete lakunja. Zingwe zotumizira mphamvu ndi zodzaza madzi zimapezeka mkati mwa pakati pa chingwe. Chingwe chilichonse chotumizira mphamvu chimakhala ndi kondakitala, gawo la chishango cha conductor, gawo loteteza kutentha, gawo la chishango choteteza kutentha, ndi gawo la chishango chachitsulo. Chubu chosasunthika chokhala ndi ulusi wowala chimaperekedwa mkati mwa pakati pa chingwe, ndipo gawo lolimbitsa losakhala lachitsulo ndi chidebe zimayikidwa motsatizana kunja kwa chubu chomasuka. Chipinda cholumikizirana cha fiber optic chokhala ndi zigawo, jekete lamkati, ndi gawo la chishango cha tepi yachitsulo zimaperekedwa motsatizana pakati pa gawo la tepi yapakati ndi jekete lakunja.
