Mosasamala kanthu za mizere yokwera ndi yotsika kwambiri komanso mizere yotsekera yodziwikiratu, pali makamaka magawo otsatirawa: mzere wozungulira, mzati wotambasula, ndodo yomangika, ndodo yama terminal ndi zina zotero.
Chigawo cha Common pole structure:
(A)mlongoti wowongoka- amatchedwanso mzati wapakati. Kukhazikitsa mu mzere wolunjika, mzati pamaso ndi pambuyo waya kwa mtundu womwewo ndi chiwerengero cha ofanana pamodzi waya pa mbali zonse za mavuto ndi wofanana, kokha mu mzere yopuma kupirira kukangana wosagwirizana mbali zonse.
(B) ndodo yamphamvu - mzere ukhoza kuchitika pakugwira ntchito kwa zolakwa za mzere wosweka ndikupangitsa nsanjayo kupirira kupsinjika, pofuna kupewa kukula kwa cholakwikacho, iyenera kukhazikitsidwa pamalo ena ndi mphamvu yayikulu yamakina, yomwe imatha kupirira Kuvuta kwa nsanja, nsanja iyi imatchedwa ndodo yomangika. Kupanikizika ndodo kukhazikitsidwa motsogozedwa ndi mzere, kuti mutha kupewa kusweka kwa mzerewo, cholakwikacho chimafalikira ku mzere wonsewo, ndipo kusamvana kokhako kumangokhala ndi boma pakati pa ndodo ziwirizo. Mtunda pakati pa awiri tensioning ndodo amatchedwa tensioning gawo kapena tensioning zida mtunda, mizere yaitali mphamvu zambiri kupereka 1 kilomita kwa gawo tensioning, komanso malingana ndi zikhalidwe ntchito kukhala yoyenera kuwonjezera kapena kufupikitsa. Mu chiwerengero cha mawaya ndi mtanda gawo la malo zasintha, komanso ntchito tensioning ndodo.
(C)mtengo wapangodyakusintha kwa njira ya mzere wapamwamba wa malo, mzati wa ngodya ukhoza kukhala wosasunthika, ukhozanso kukhala wozungulira, malinga ndi nsanja yodzaza ndi waya wovuta.
(D)terminal pole - ndi pamwamba mzere kwa chiyambi ndi mapeto, chifukwa terminal mzati mbali imodzi yokha ya kondakitala, nthawi yachibadwa komanso kupirira mavuto, kotero kukhazikitsa chingwe.
Mtundu wa kondakitala: Waya wokhazikika wa zitsulo zotayidwa ndi aluminiyamu uli ndi mphamvu zokwanira zamakina, madulidwe abwino amagetsi, kulemera kopepuka, mtengo wotsika, kukana dzimbiri, amagwiritsidwa ntchito kwambiri mumizere yamagetsi apamwamba kwambiri.
Gawo locheperako la kondakitala silochepera 50mm² pamizere yodzitsekera yokha ndi 50mm² podutsa mizere.
Mzere phula: kusankha phula ndi koyenera kutenga zigwa zokhalamo 60-80m, malo osakhalamo 65-90m, komanso malinga ndi momwe zilili pamalowo.
Kusintha kwa kondakitala: kondakitala akuyenera kutengera gawo lonselo, kusintha kulikonse kwa 3-4km, nthawi iliyonse kuti akhazikitse kazungulira, pambuyo pa kusinthika, kusanayambike kwa gawolo kuyenera kusungidwa poyambitsa magawo awiri oyandikana nawo. mzere womwewo. Udindo: kupewa kusokoneza kulumikizana kwapafupi ndi mizere yotseguka ndi mizere yolumikizira; kupewa voteji kwambiri.
Magulu a mizere yamagetsi apamwamba, kaya ndi mizere yothamanga kwambiri, mizere yotsika kwambiri kapena mizere yodulira yokha, imatha kugawidwa m'mitundu iyi: mitengo yowongoka, mizati yopingasa, mizati yomangira ndi mizati.
1. Gulu la zida zodziwika bwino zamagetsi zamagetsi
Mtundu umodzi. Mzati Yowongoka: Imadziwikanso kuti pakati, yomwe imayikidwa pagawo lowongoka, pomwe mtundu ndi kuchuluka kwa ma conductor ndi ofanana, kukangana kwa mbali zonse za mtengo kumakhala kofanana. Zimangolimbana ndi kusagwirizana kosagwirizana mbali zonse pamene woyendetsa akuswa.
Imayikidwa pagawo lolunjika pamene otsogolera ali amtundu womwewo ndi nambala. b. Mitengo Yosasunthika: Mzere ukaduka, mzerewo ukhoza kukhala ndi mphamvu zolimba. Pofuna kupewa kufalikira kwa zolakwika, ndikofunikira kuyika ndodo zokhala ndi mphamvu zamakina apamwamba komanso zotha kupirira kupsinjika pamalo enaake, otchedwa mipiringidzo yamavuto. Ndodo zomangika zimaperekedwa ndi mizere yolumikizirana pamzerewu kuti apewe kufalikira kwa zolakwika komanso kuchepetsa kusamvana pakati pa ndodo ziwiri zomangika. Mtunda wapakati pa ndodo ziwiri zomangika umatchedwa gawo la tension kapena tension span, yomwe nthawi zambiri imayikidwa pa 1 km kwa mizere yamagetsi yayitali, koma imatha kusinthidwa malinga ndi momwe zimagwirira ntchito. Ndodo zomangika zimagwiritsidwanso ntchito pomwe nambala ndi magawo a ma conductor amasiyanasiyana.
c. Ndodo za ngodya: Zimagwiritsidwa ntchito ngati kusintha kolowera pazingwe zamagetsi zam'mwamba. Miyendo ya ma angles imatha kupindika kapena kusinthidwa. Kuyika kwa mizere yamphamvu kumadalira kupsinjika kwa mtengo.
d. Zolemba Zoyimitsa: Zogwiritsidwa ntchito poyambira ndi kumapeto kwa chingwe chamagetsi chapamwamba. Nthawi zambiri, mbali imodzi ya positi yotsekera imakhala yolimba ndipo imakhala ndi waya wopumira.
Mtundu wa Conductor: Waya wa Aluminium core stranded (ACSR) amagwiritsidwa ntchito kwambiri pazingwe zamagetsi zamagetsi apamwamba kwambiri chifukwa cha mphamvu zake zokwanira zamakina, kuyendetsa bwino kwamagetsi, kulemera kopepuka, mtengo wotsika komanso kukana dzimbiri. Pa mizere yopitilira 10 kV, ma conductor amagawidwa kukhala ma conductor opanda kanthu ndi ma kondakitala a insulated. Makokitala otchingidwa nthawi zambiri amagwiritsidwa ntchito m'malo okhala ndi nkhalango komanso malo opanda malo osakwanira.
Conductor cross-section: Mawaya a aluminiyamu achitsulo okhala ndi gawo lochepera lochepera 50mm² nthawi zambiri amagwiritsidwa ntchito podzitsekera okha komanso kudutsa mizere.
Mtunda wa mzere: Mtunda pakati pa mizere m'malo okhalamo okhalamo ndi 60-80m, ndipo mtunda wapakati pa mizere m'malo osakhalamo ndi 65-90m, womwe ungasinthidwe molingana ndi momwe zilili pamalopo.
Kusintha kwa kondakitala: Kondakitala akuyenera kutembenuzidwanso pa mtunda wa makilomita 3-4 aliwonse, ndipo chigawo chilichonse chiyenera kukhazikitsidwa. Pambuyo pozungulira, gawo la malo odyetserako oyandikana nawo liyenera kukhala lofanana ndi gawo lisanakhazikitsidwe poyambira. Izi ndi kupewa kusokoneza kulankhulana pafupi ndi mizere siginecha ndi kupewa overvoltage.
