Zofunikira zonse pamizere yapamwamba:

Mizere yapamwambaAyenera kugwiritsa ntchito kwambiri waya wazitsulo wazitsulo za aluminiyamu kapena waya wokhazikika wa aluminiyumu.The mtanda gawo la aluminiyamu stranded waya wa mkulu-voteji pamwamba mzere adzakhala zosakwana 50 lalikulu millimeters, mtanda gawo la pachimake zotayidwa stranded waya sayenera zosakwana 35 mamilimita lalikulu;mtanda gawo la waya opanda kanthu adzakhala osachepera 16 lalikulu millimeters.

Gawo la mtanda wa waya liyenera kukwaniritsa zofunikira za katundu wambiri.
Kusankhidwa kwa gawo la mtanda kuyeneranso kukumana ndi kutayika kwa magetsi osapitirira 5% yamagetsi ovotera (mizere yamagetsi apamwamba), kapena 2% mpaka 3 (mizere yowunikira yokhala ndi zofunikira zazikulu zowonekera).Ndipo ayenera kukumana wina mawotchi mphamvu.

Kupanga mizere pamwamba
Njira yopangira mafotokozedwe ndi masitepe a mzere wapamwamba ndi awa:

Muyezo wa mzere: fufuzani malo ndi mawonekedwe molingana ndi chojambula chojambula, dziwani poyambira mzere, ngodya ndi malo amtengo wa sitolo yosungiramo katundu, potsirizira pake dziwani malo apakati ndi mtengo wolimbikitsira ndikuyika mtengo.

Kubweza kumbuyo kwa zokumba dzenje la maziko: Pofukula dzenje la maziko, chidwi chiyenera kuperekedwa ku mtundu wa nthaka ndi malo ozungulira.Kukula kwa dzenje nthawi zambiri kumakhala 0.8 mita mulifupi ndi 0.3 mita kutalika.Kukula kwa dzenje lawaya nthawi zambiri ndi 0.6 mita mulifupi ndi 1.3 mita utali.Chidziwitso cha mtengo wokwiriridwa wa mtengowo ndi motere:

Kutalika kwa mtengo wa simenti (m) 7 8 9 10 11 12 15
Kuya kokwiriridwa (m) 1.1 1.6 1.7 1.8 1.9 2.0 2.5
Pamene backfilling nsanja maziko ndi chingwe maziko, saloledwa backfill mtengo mizu, udzu, etc. Nthaka ayenera akaumbike kuposa kawiri, ndi backfill ayenera kukhala 30-50 masentimita pamwamba pa nthaka.

Mzati: Mitengo yamagetsi imagwiritsidwa ntchito kuthandizira mawaya pamizere ya pamwamba.Pali mitundu yambiri yazitsulo zamagetsi, ndipo zofala ndizozitsulo zofananira, mizati yamakona, mizati yotsiriza, ndi zina zotero malinga ndi ntchito zawo.Njira zogwiritsiridwa ntchito kwambiri ndi: mitengo ya crane, mitengo ya katatu, ndodo zozondoka ndi zoyimilira.

Mlongoti wa tripod ndi njira yosavuta yokhazikitsira mtengowo.Zimadalira kachingwe kakang'ono ka katatu kuti akweze mtengowo.Mlongoti ukamangidwa, choyamba sunthani mtengowo m'mphepete mwa dzenje, ikani katatu, ndikuyika mtengowo pamtengowo.Zingwe zitatu zokoka zimamangidwa kunsonga kuti ziwongolere thupi la mtengowo, kenako mtengowo amaumitsidwa ndikugwetsera mu dzenje la mtengo, ndipo pamapeto pake thupilo limasinthidwa ndikuphatikizana.
Cross mkono msonkhano: Cross mkono ndi bulaketi khazikitsa insulators, switchgear, zomangira, etc. Malinga ndi nkhani, pali matabwa mtanda mikono, chitsulo mtanda mikono ndi ceramic mtanda mikono.Dzanja la mtanda la ndodo liyenera kuikidwa pambali ya katundu, ndipo ndodo yopanda mzere iyenera kuikidwa mbali ina ya zovutazo.

Ma insulators: Ma insulators amagwiritsidwa ntchito kusunga mawaya.Choncho iyenera kukhala ndi mphamvu zokwanira zamagetsi zamagetsi komanso mphamvu zamakina.Ma insulators omwe amagwiritsidwa ntchito kwambiri pamizere yopitilira pamwamba amaphatikiza ma pin insulators, suspension insulators, butterfly insulators, ndi zina zotere. Mphamvu yamagetsi yamagetsi otsika ndi 1kV, ndipo ma insulators okwera kwambiri amagwiritsidwa ntchito pamizere ya 3kV, 6kV, ndi 10kV.

Kupanga mawaya: Kukoka waya pamzere wapamwamba kumagwira ntchito yothandizira mlongoti.Nthawi zambiri, ndodo yapangodya, ndodo yomaliza, ndodo yomangika, ndi zina zotero, ziyenera kukhala ndi chingwe chokoka kuti zichirikize mlongoti, kuti zisakhoteke chifukwa cha kugwedezeka kwa waya.Nthawi zambiri, ngodya pakati pa chingwe ndi pansi ndi pakati pa 30 ° ndi 60 °, ndipo chogwirira chingwe, chingwe chapakati, ndi chingwe chapansi chimakonzedwa motsatira.

Njira yoimitsira mawaya: kuyika mawaya kumaphatikizapo kuyala, kulumikiza mawaya, mawaya olendewera ndi mawaya omangitsa, ndi zina zotere. Kulipira ndiko kumasula waya ku spool ndikuyiyika pamtengo wopingasa mkono.Pali mitundu iwiri ya masanjidwe a mzere: kukokera ndi kugwetsa ndi njira yofalitsa.Ma kondakitala a mawaya apamtunda nthawi zambiri amalumikizidwa ndi splicing, kumanga, ndi crimping.Kupachika waya ndi kukoka waya pamtengo ndi chingwe chaching'ono ndikuchiyika pamtanda.Kulimbitsa waya ndikumangirira mwamphamvu waya ku insulator pamapeto amodzi a kukana kukaniza, ndikumangirira ndi waya wolimba kumapeto kwina.Sag ndi chiwombankhanga chachilengedwe chomwe chimapangidwa ndi kutsetsereka kwa waya mkati mwa span.

Kutsatizana kwa gawo la magawo atatu a mzere wapamwambawo kudzakwaniritsa zofunikira izi: kuchokera kumbali yakumanzere moyang'anizana ndi katundu, gawo lotsatizana la makonzedwe a kondakitala ndi L1, N, L2, L3, ndipo mzere wosalowerera ndale nthawi zambiri umakhala pa. mbali ya msewu wa mtengo.Mitengo yamagetsi nthawi zambiri imayikidwa kumpoto ndi kum'mawa kwa msewu.
