Mahwendefa ejoko remagetsi anonyanya kushandiswa mumitsara yekufambisa pamusoro uye akakodzera kumamiriro ekushanda akasiyana, akadai se: 110kV–220kV: mahwendefa ejoko ane mativi matatu anogona kusarudzwa kune rimwe chete-kurembera kwetambo nemajoko akapatsanurwa kaviri-ukuwo Z{4}}mhando dzejoko dzemajoko dzichishandiswa kukona kwekurudyi{5}} 330kV–500kV: rectangular neLF types dzinoshandiswa kuita kaviri-string tension split joko, ukuwo maLL marudzi achishandiswa mana-split single-string suspension; 750kV–1000kV: inonyanya kuchinjirwa kune-zvikamu zvetension kwenguva refu kuti zvitsivise kunetsa uye kutsauka kwemhepo.
Mahwendefa ejoko remagetsi anonyanya kugadzirwa nesimbi, zvichiita kuti aite ngura. Kurapwa kwepamusoro chinhu chakakosha pakuona kuti hupenyu hwavo hurefu sei uye hunofanirwa kuenderana nehwaro hwezvinhu uye kuzadzisa zviyero zvepasi rose zvekutengesa kunze. Kupisa-dip galvanizing inzira isingadhuri uye inoshanda yekurapa. Iyo ndiro yakabikwa yejoko inonyudzwa mu zinc yakanyungudutswa, ichiita yunifomu zinc layer pamusoro. Iyi zinc layer inopa chibayiro anode dziviriro, kudzivirira ngura kunyangwe nzvimbo yakakwenya. Miyedzo yekupfapfaidza yemunyu inoratidza kuti hapana ngura yakatsvuka mushure memaawa anopfuura makumi mapfumbamwe nematanhatu, uye kushandiswa kwekunze kunogona kugara makore makumi maviri-makumi matatu. Inoenderana nezvinhu zvakaita seQ235, Q345, uye ductile iron.
Patinenge tichishandisa Electric Yoke Plate munzvimbo dzinotyisa, tinofanira kufunga nezvehuwandu hwekuora kwezvakatipoteredza uye chiyero chekudzivirira kusvibiswa kwezvinhu, sarudza substrate yakakodzera uye pamusoro pekugadzirisa mhinduro, uye panguva imwe chete, tora matanho ekugadzirisa akakodzera.
Kune zvinyoro zvinyoro zvekuora, zvakaita semapani, nzvimbo dzine makomo, uye nharaunda dzisina kusvibiswa kwemaindasitiri, hapana kudzika kwakadzika, uye kukanganisa kwesimba remagetsi kushoma.
Kuora kuri pakati nepakati: Munzvimbo dziri pedyo nezvirimwa zvemakemikari zvine humidity yakakwira (semuenzaniso, 60% -80%), kunyangwe paine zinc layer pamusoro, iyo zinc layer ichakurumidza kupedzwa, uye gomba kukoromoka kuchaitika musubstrate. Simba reMechanical rinowanzo kukanganiswa mushure memakore 5-10 ekushandiswa.
Kuora kwakanyanya: Munzvimbo dzekupfapfaidza munyu mumhenderekedzo yegungwa, mapuratifomu ekumahombekombe, minda yemunyu, mapaki emaindasitiri emakemikari, nenzvimbo dzinonaya mvura yeasidhi, huwandu hwekuora hwakanyanya. Iyo yepakati ichakurumidza kupinda mukati mekudzivirira, uye iyo substrate corrosion rate inokurumidza zvakare. Pane njodzi yekuputsika mushure memakore 3-5 ekushandiswa.
Kusarudzwa kwe substrate kunobata zvakananga hupenyu hwebasa rejoko rejoko remagetsi. Mukuwedzera, inobatanawo nezvimwe zvinhu zvakawanda. Kuti tisangane nezvinodiwa zvekutengeserana kunze kwenyika, isu tichawedzera mamwe ekudzivirira pazasi.
Mamiriro ezvinhu
Kune majoko ane zvimiro zvakaoma, senge maburi ekukwira akawanda kana makona asina kujairika, kuunganidzwa kwemvura kwakafa nzvimbo dzinogona kuumba, uko munyu wekupfapfaidza, mvura inonaya, uye guruva remaindasitiri zvinogona kuungana, zvichitungamira mukuora kwenzvimbo, kukuvadzwa kwechidziviriro, uye gomba regomba re substrate. Naizvozvo, kana tichishandiswa munzvimbo dzinoita ngura, tinofanira kukoshesa majoko ane zvimiro zviri nyore, nzvimbo dzakatsetseka, uye materu emvura.
Stress distribution
Kana ndiro yacho yakanyanya kutetepa, radius yekona yakanyanya kuduku, kana kuti chikamu chemuchinjikwa chisina kuenzana, zvinotungamirira kune kushushikana mupfungwa. Munzvimbo ine ngura, kushushikana kwepfungwa kunokonzeresa kuparara kwekuora mwoyo, inovawo nzira huru yekukundikana kwepamusoro-mahwendefa ejoko akasimba munzvimbo dzine ngura. Naizvozvo, isu tinofanirwa kusarudza mukobvu weplate uri 20% kusvika 30% yakakura kupfuura iyo iri munzvimbo yakajairwa, shandisa mikuru yemakona radius transitions, uye ive neyunifomu uye symmetrical cross chikamu kudzivirira kushushikana kushushikana.
Kukodzera kururama
Yakawandisa yekuisa magapu pakati peElectric Yoke Plate uye insulators, mabhaudhi, uye mabhaudhi zvinogona kutungamirira kune crevice corrosion. Okisijeni yemukati mukati megeji yakadzikira pane iyo yekunze, ichigadzira sero reokisijeni, izvo zvinokonzeresa kukurumidza kuora kweiyo substrate mukati megeji, zvichiita kuti bhaudhi jamming uye yejoko ndiro kuputsika. Naizvozvo, zvinodikanwa kuti uone iko kurongeka kwakakodzera, kuisa pamberi peiyo planar kuonana, kudzivirira poindi kana mutsara kubata, uye kuderedza gap nzvimbo.
