Kapangidwe ndi njira zotetezera zingwe zopanda madzi
Kapangidwe ka zingwe zopanda madzi nthawi zambiri zimasiyanasiyana malinga ndi momwe amagwiritsidwira ntchito komanso kuchuluka kwamagetsi. Kwa zingwe zotchingira madzi zokha,tepi yotsekera madzi yotsekerakapena wambatepi yotchinga madzinthawi zambiri amakulungidwa pazitsulo zotchinga zotchinga, ndipo zowonjezera zowonjezera madzi zimatha kukhazikitsidwa kunja kwa zitsulo zotchinga. Nthawi yomweyo, ufa wotsekera madzi kapena zingwe zotsekera madzi zimaphatikizidwa kuti zithandizire kusindikiza kwathunthu. Zida za sheath zimakhala ndi polyethylene yapamwamba kwambiri (HDPE) kapena mphira wapadera wokhala ndi ntchito yotchinga madzi, yomwe imagwiritsidwa ntchito kupititsa patsogolo mphamvu yamadzi yopanda madzi.
Kwa zingwe zapakati-pakatikati kapena zapakati komanso zazitali, kuti ziwongolere magwiridwe antchito amadzi, tepi ya aluminiyamu yokhala ndi pulasitiki nthawi zambiri imakulungidwa motalika mkati mwa wosanjikiza wamkati kapena m'chimake, pomwe sheath ya HDPE imatuluka panja kuti ipange gulu lopanda madzi. Zapolyethylene yolumikizidwa (XLPE)zingwe zotsekera za 110kV ndi kupitilira magiredi, zitsulo zachitsulo monga aluminiyamu yoponderezedwa, lead yopanikizidwa ndi moto, aluminiyamu wonyezimira, kapena zitsulo zachitsulo zozizira nthawi zambiri zimagwiritsidwa ntchito popereka mphamvu zoteteza ma radial.
Njira yodzitchinjiriza ya zingwe zopanda madzi: kutsekereza kotalika komanso kozungulira
Njira zotchingira madzi za zingwe zopanda madzi zitha kugawidwa kukhala zotalikirapo zoletsa madzi komanso zotchingira madzi. Kuteteza madzi kwa nthawi yayitali kumadalira makamaka zinthu zotsekereza madzi, monga ufa wotsekereza madzi, ulusi wotsekereza madzi, ndi tepi yotsekereza madzi. Madzi akalowa, adzakula mofulumira kuti apange gawo lodzipatula, kuteteza madzi kuti asafalikire kutalika kwa chingwe. Kutsekereza madzi kumapangitsa kuti madzi asalowe mu chingwe kuchokera kunja kudzera m'chimake kapena zitsulo. Zingwe zopanda madzi zapamwamba nthawi zambiri zimaphatikiza kugwiritsa ntchito njira ziwiri kuti akwaniritse chitetezo chokwanira chamadzi.
Kusiyana pakati pa zingwe zopanda madzi ndi zingwe zotsekereza madzi
Ngakhale kuti zolinga za ziwirizi n'zofanana, pali kusiyana koonekeratu kwa mfundo zamapangidwe ndi zochitika zogwiritsira ntchito. Mfundo yofunika kwambiri ya zingwe zopanda madzi ndikuletsa madzi kulowa mkati mwa zingwe. Mapangidwe awo nthawi zambiri amatengera zitsulo zachitsulo kapena zida zolimba kwambiri, kutsindika kutsekereza madzi. Ndioyenera malo okhala pansi pamadzi kwanthawi yayitali monga mapampu apansi pamadzi, zida zapansi panthaka, ndi ngalande zonyowa. Koma zingwe zotsekera madzi zimangoganizira kwambiri za momwe angaletsere madzi kufalikira akalowa. Amagwiritsa ntchito kwambiri zinthu zotsekereza madzi zomwe zimakula akakumana ndi madzi, monga ufa wotsekereza madzi, ulusi wotsekereza madzi, ndi tepi yotchinga madzi, kuti akwaniritse zotchinga madzi nthawi yayitali. Amagwiritsidwa ntchito kwambiri pazinthu zogwiritsira ntchito monga zingwe zoyankhulirana, zingwe zamagetsi, ndi zingwe zowunikira. Mapangidwe onse a zingwe zopanda madzi ndizovuta kwambiri ndipo mtengo wake ndi wokwera kwambiri, pamene zingwe zotsekera madzi zimakhala ndi mawonekedwe osinthika komanso otsika mtengo, ndipo ndizoyenera kuyika malo osiyanasiyana.
Mau Oyamba a Mafomu Otsekera Madzi (a Zingwe Zotsekera Madzi)
Zomangamanga zotsekereza madzi zimatha kugawidwa m'magulu oletsa madzi opangira madzi komanso zomangira zotsekera madzi molingana ndi malo amkati a chingwe. Mapangidwe oletsa madzi a ma conductor amaphatikizapo kuwonjezera ufa wotsekereza madzi kapena ulusi wotsekereza madzi panthawi yopindika ya ma conductor kuti apange gawo lotchinga madzi longitudinal. Ndikoyenera pazochitika zomwe kuli kofunikira kuteteza kufalikira mkati mwa oyendetsa. Mapangidwe oletsa madzi a chingwe chachitsulo amawonjezera tepi yotchinga madzi mkati mwa chingwe cha chingwe. Pamene sheath yawonongeka ndipo madzi amalowa, amakula mofulumira ndikutseka njira zapakati pa chingwe, kuteteza kufalikira kwina. Pazinthu zamitundu yambiri, tikulimbikitsidwa kutengera mapangidwe odziyimira pawokha otsekereza madzi pachimake chilichonse motsatana kuti apange malo akhungu otsekereza madzi omwe amayamba chifukwa cha mipata yayikulu ndi mawonekedwe osakhazikika a zingwe zamagetsi, potero kumathandizira kudalirika kwamadzi.
