Imigca engaphezulu ibhekisa ikakhulu kwimigca engaphezulu evulekileyo, emiswe phantsi. Ingumzila wothumelo osebenzisa i-insulators ukulungisa iingcingo zothumelo kwiipali kunye neenqaba ezithe tye emhlabeni ukuhambisa amandla ombane. Ukwakhiwa kunye nokugcinwa kulungele kwaye iindleko ziphantsi, kodwa kulula ukuchatshazelwa yimozulu kunye nokusingqongileyo (njengomoya, ukubetha kombane, ukungcola, ikhephu kunye neqhwa, njl.) kwaye kubangele iimpazamo. Ngeli xesha, yonke ipaseji yokuhambisa amandla ithatha indawo enkulu yomhlaba, ekulula ukubangela ukuphazamiseka kombane kwindawo engqongileyo.
Amacandelo aphambili omgca we-overhead zezi: i-conductor kunye nentonga yombane (ucingo olungaphezulu komhlaba), inqaba, i-insulator, izixhobo zegolide, isiseko senqaba, ikhebula kunye nesixhobo sokumisa.
umqhubi
Ucingo licandelo elisetyenziselwa ukuqhuba ngoku kunye nokudlulisa amandla ombane. Ngokubanzi, kukho i-eriyali engenanto ikhondaktha kwisigaba ngasinye. I-220kV kunye neentambo ezingaphezulu, ngenxa yomthamo wazo omkhulu wothumelo, kwaye ukuze kuncitshiswe ilahleko ye-corona kunye nokuphazamiseka kwe-corona, ukwamkela iikhondatha zokwahlulwa kwesigaba, oko kukuthi, izikhondatha ezimbini nangaphezulu kwisigaba ngasinye. Ukusetyenziswa kocingo oluqhekezayo kunokuthutha amandla amakhulu ombane, kunye nokulahlekelwa kwamandla amancinci, kunomsebenzi ongcono wokuchasana nokungcangcazela. Ucingo olusebenzayo luhlala luvavanywa ngeemeko ezahlukeneyo zendalo, kufuneka lube nokusebenza kakuhle kokuqhuba, amandla omatshini aphezulu, umgangatho wokukhanya, ixabiso eliphantsi, ukuxhathisa okuqinileyo kwe-corrosion kunye nezinye iimpawu. Ngenxa yokuba izixhobo ze-aluminium zininzi kakhulu kunobhedu, kwaye ixabiso le-aluminium kunye nobhedu lihluke kakhulu, phantse zonke iintambo zentsimbi eziphothiweyo zisetyenziswa. Umqhubi ngamnye uya kuba noqhagamshelo olunye kumgama wegiya nganye. Kwiindlela ezinqumlayo, imilambo, imizila kaloliwe, izakhiwo ezibalulekileyo, iintambo zombane kunye neentambo zonxibelelwano, iikhondaktha kunye nezibambisi mbane aziyi kuba nalunxibelelwano.
Ukubamba umbane
Intonga yombane ngokuqhelekileyo yenziwe ngentsimbi engundoqo ye-aluminium, kwaye ayifakwanga kwinqaba kodwa imiswe ngokuthe ngqo phezulu kwinqaba, kwaye idibaniswe nesixhobo sokumisa phantsi kwinqaba okanye isikhokelo somhlaba. Umsebenzi wocingo olubamba umbane kukunciphisa ithuba lokubetha kombane, ukuphucula inqanaba lokumelana nombane, ukunciphisa amaxesha okuhamba kombane, kunye nokuqinisekisa ukuhanjiswa okukhuselekileyo kweentambo zombane.
Ipali kunye nenqaba
I-Tower ligama eliqhelekileyo lepali yombane kunye nenqaba. Injongo yesibonda kukuxhasa ucingo kunye nesibambisi sombane, ukwenzela ukuba ucingo phakathi kocingo, ucingo kunye nesibambisi sombane, ucingo kunye nomhlaba kunye nokuwela phakathi komgama othile okhuselekileyo.
isigqubuthelo
I-Insulator luhlobo lweemveliso zokufakelwa kombane, ezenziwe ngokubanzi ngeeseramikhi zombane, ezaziwa ngokuba yibhotile ye-porcelain. Kukho ne-insulators yeglasi eyenziwe ngeglasi epholileyo kunye ne-synthetic insulators ezenziwe ngerabha ye-silicone. I-insulators isetyenziselwa ukugquma iingcingo kunye naphakathi kweengcingo kunye nomhlaba, ukuqinisekisa amandla ombane athembekileyo okufakelwa kweengcingo, kunye nokulungisa iingcingo kunye nokumelana nomthwalo othe nkqo kunye othe tye weingcingo.
Izixhobo zegolide
Kwiintambo zamandla ezingaphezulu, izifakelo zisetyenziselwa ukuxhasa, ukulungisa nokudibanisa iingcingo kunye ne-insulators kwiintambo, kunye nokukhusela iingcingo kunye ne-insulators. Ngokomsebenzi ophambili kunye nokusetyenziswa kwe-hardware, inokwahlulwa ngokwezi ndidi zilandelayo:
1, iklasi yekliphu yomgca. I-wire clamp isetyenziselwa ukubamba isikhokelo, ucingo oluphantsi lwegolide
2. Ukudibanisa i-hardware. Izixhobo zokudibanisa zisetyenziselwa ukudibanisa i-insulators yokunqunyanyiswa kwiintambo, kunye nokudibanisa kunye nokuxhoma iintambo ze-insulator kwintonga.
Kwingalo yomnqamlezo wenqaba.
3, ukuqhubeka kodidi lwegolide. Isidibanisi esisetyenziselwa ukudibanisa iingcingo ezahlukeneyo, isiphelo sentonga yombane.
4, khusela udidi lwegolide. Izixhobo zokukhusela zahlulwe zibe ngamacandelo amabini omatshini kunye nombane. Izixhobo zokukhusela oomatshini kukuthintela isikhokelo kunye nocingo oluphantsi ukuba luqhekeke ngenxa yokungcangcazela, kunye nezixhobo zokukhusela umbane kukuthintela umonakalo ongaphambi kwexesha wee-insulators ngenxa yokusabalalisa okunzima kombane. Iindidi zoomatshini zinesando esichasene ne-vibration, ibha yokukhusela i-wire pre-stranded, isando esinzima, njl.; Igolide yombane eneringi yokulinganisa uxinzelelo, umsesane okhuselayo, njl.
Isiseko senqaba
Izixhobo ezingaphantsi komhlaba zentambo yombane ongaphezulu zibizwa ngokudibeneyo njengesiseko. Isiseko sisetyenziselwa ukuzinzisa inqaba, ukwenzela ukuba inqaba ayiyi kutsalwa phezulu, ukucwila okanye ukudilika ngenxa yomthwalo othe nkqo, umthwalo othe tye, ukuxhatshazwa kwengozi kunye namandla angaphandle.
Tsala ucingo
Ikhebula lisetyenziselwa ukulinganisa umthwalo onqamlezayo kunye noxinzelelo lwecingo olusebenza kwinqaba, enokunciphisa ukusetyenziswa kwezixhobo zenqaba kunye nokunciphisa iindleko zomgca.
Isixhobo somhlaba
Ucingo olungaphezulu komhlaba luphezu kocingo, luya kudityaniswa emhlabeni ngocingo olusemhlabeni okanye umzimba osemhlabeni wenqaba nganye yesiseko. Xa umbane ubetha kucingo olusemhlabeni, unokukhawuleza usasaze ukuhamba kombane emhlabeni. Ngoko ke, isixhobo sokumisa
