Imigqa engaphezulu ngokuyinhloko ibhekisela emigqeni evulekile ephezulu, emiswe phansi. Iwulayini wokudlulisela osebenzisa izivikela magciwane ukuze ulungise izintambo zokudlulisela ezigxotsheni nemibhoshongo iqonde phansi ukuze idlulise amandla kagesi. Ukumiswa nokugcinwa kwempahla kulula futhi izindleko ziphansi, kodwa kulula ukuthintwa isimo sezulu kanye nemvelo (njengomoya, ukushaywa kombani, ukungcola, iqhwa neqhwa, njll.) futhi kubangele amaphutha. Ngaleso sikhathi, wonke umhubhe wokudluliswa kwamandla uthatha indawo enkulu yomhlaba, okulula ukubangela ukuphazamiseka kozibuthe endaweni ezungezile.
Izingxenye eziyinhloko zomugqa ongaphezulu yilezi: i-conductor kanye nenduku yombani (intambo engaphezulu komhlaba), umbhoshongo, isivikelo, amathuluzi egolide, isisekelo sombhoshongo, ikhebula kanye nensiza ephansi.
umqhubi
Ucingo luyingxenye esetshenziselwa ukuqhuba nokudlulisa amandla kagesi. Ngokuvamile, kunekhondatha eyodwa yasemoyeni engenalutho yesigaba ngasinye. Imigqa engu-220kV nangaphezulu, ngenxa yomthamo wawo omkhulu wokudlulisa, futhi ukuze kwehliswe ukulahleka kwe-corona kanye nokuphazamiseka kwe-corona, sebenzisa amakhondatha okuhlukanisa izigaba, okungukuthi, amakhondatha amabili noma ngaphezulu esigabeni ngasinye. Ukusetshenziswa kwentambo ehlukanisiwe kungathutha amandla kagesi amakhulu, kanye nokuncipha kwamandla amancane, kunokusebenza okungcono kokulwa nokudlidliza. I-wire esebenzayo ivame ukuhlolwa ngezimo ezihlukahlukene zemvelo, kufanele ibe nokusebenza okuhle kokusebenza, amandla aphezulu emishini, ikhwalithi yokukhanya, intengo ephansi, ukumelana nokugqwala okuqinile nezinye izici. Ngenxa yokuthi izinsiza ze-aluminium ziningi kakhulu kunethusi, futhi intengo ye-aluminium nethusi ihluke kakhulu, cishe zonke izintambo ezisontekile ze-aluminium core zisetshenziswa. Ikhondaktha ngayinye izoba nokuxhumana okukodwa kuphela ebangeni legiya ngalinye. Emigwaqweni ewela imigwaqo, emifuleni, kwezitimela, ezakhiweni ezibalulekile, izintambo zikagesi nezintambo zokuxhumana, amakhondakta nezinqamuli zombani ngeke zixhunywe.
Isibambi sombani
Induku yombani ngokuvamile yenziwe ngocingo oluyinsimbi oluyinsimbi oluyi-aluminium, futhi ayivalwanga nombhoshongo kodwa imiswe ngokuqondile phezulu kombhoshongo, futhi ixhunywe nensiza yaphansi ngombhoshongo noma umthofu ophansi. Umsebenzi wezintambo ezibamba umbani ukunciphisa ithuba lokushaya umbani, ukuthuthukisa izinga lokumelana nombani, ukunciphisa izikhathi zohambo lombani, nokuqinisekisa ukudluliswa okuphephile kwezintambo zikagesi.
Isigxobo nombhoshongo
Umbhoshongo igama elijwayelekile lesigxobo sikagesi nombhoshongo. Inhloso yesigxobo ukusekela ucingo kanye nesibambisi sombani, ukuze ucingo phakathi kocingo, ucingo kanye nesibambisi sombani, ucingo nomhlabathi kanye nokuwela phakathi kwebanga elithile eliphephile.
isivikelo
I-insulator iwuhlobo lwemikhiqizo yokufakwa kukagesi, ngokuvamile eyenziwa ngezitsha zobumba zikagesi, ezaziwa nangokuthi ibhodlela le-porcelain. Kukhona nama-insulators engilazi enziwe ngengilazi epholile kanye nama-insulators okwenziwa enziwe ngerabha ye-silicone. Ama-insulators asetshenziselwa ukuvala izintambo naphakathi kwezintambo nomhlaba, ukuqinisekisa ukuthi izintambo zinamandla okuvimba ugesi, nokulungisa izintambo futhi zimelane nomthwalo oqondile novundlile wezintambo.
Amathuluzi egolide
Ezintamboni zamandla angaphezulu, okokufakwa kusetshenziswa kakhulu ukusekela, ukulungisa nokuxhuma izintambo nama-insulators zibe yizintambo, futhi nokuvikela izintambo nama-insulators. Ngokusho kokusebenza okuyinhloko nokusetshenziswa kwehadiwe, kungahlukaniswa ngezigaba ezilandelayo:
1, isigaba sesiqeshana somugqa. I-wire clamp isetshenziselwa ukubamba inkomba, intambo yaphansi yegolide
2. Ukuxhuma ihadiwe. Ukufakwa okuhlanganisayo kusetshenziswa ikakhulukazi ukuhlanganisa ama-insulators amisiwe abe yizintambo, futhi axhume futhi amise izintambo zesivikelo entweni.
Engalweni yesiphambano sombhoshongo.
3, ukuqhubeka kwesigaba segolide. Isixhumi esisetshenziselwa ukuxhuma izintambo ezihlukahlukene, ukuphela kwenduku yombani.
4, vikela isigaba segolide. Imishini yokuzivikela ihlukaniswe yaba izigaba ezimbili zemishini kanye nekagesi. Imishini yokuvikela umakhenikha iwukuvimbela inkomba kanye nocingo oluphansi ukuthi lungagqabhuki ngenxa yokudlidliza, futhi okokusebenza kokuvikela ugesi ukuvikela ukulimala ngaphambi kwesikhathi kwezivikeli ngenxa yokusabalalisa kukagesi okungalingani. Izinhlobo zemishini zinesando esinqanda ukudlidliza, ibha yokuvikela ucingo oluboshwe ngaphambili, isando esindayo, njll.; Igolide likagesi elinendandatho yokulinganisa ingcindezi, indandatho yokuvikela, njll.
Isisekelo sombhoshongo
Amadivayisi angaphansi komhlaba ombhoshongo wentambo yamandla angaphezulu abizwa ngokuhlanganyela ngokuthi isisekelo. Isisekelo sisetshenziselwa ukuzinzisa umbhoshongo, ukuze umbhoshongo ungadonselwa phezulu, uzike noma ugingqike ngenxa yomthwalo oqondile, umthwalo ovundlile, ukungezwani kokuphuka kwengozi namandla angaphandle.
Donsa ucingo
Ikhebula lisetshenziselwa ukulinganisa umthwalo oguquguqukayo kanye nokungezwani kocingo okusebenza embhoshongweni, okunganciphisa ukusetshenziswa kwezinto zombhoshongo futhi kunciphise izindleko zomugqa.
Idivayisi yomhlabathi
Intambo yaphansi engaphezulu ingaphezu kwentambo, izoxhunywa emhlabeni ngentambo yaphansi noma umzimba ophansi wombhoshongo wesisekelo ngamunye. Lapho umbani ushaya ucingo lwaphansi, lungasakaza ngokushesha ukugeleza kombani emhlabeni. Ngakho-ke, idivayisi ephansi
