Incazelo Yomkhiqizo

Njengengxenye ebalulekile yokufakwa kwamandla kagesi, ukusetshenziswa kwama-spacer rods kuvame ukusetshenziswa emigqeni yokudlulisela yegridi yamandla kagesi yaseChina, futhi isidingo sokukhiqiza sawo siyanda.Ukuze uvimbele ukushaywa phakathi kwezintambo futhi unciphise ukudlidliza kwezintambo ezibangelwa umoya, indima yesikhala phakathi kwezintambo ibaluleke kakhulu, efana nomphumela wesando sokudlidliza, kodwa umsebenzi oyinhloko we- i-spacer iwukucindezela ukudlidliza phakathi kwezikhala .
I-spacer rod ibhekisela ekufakweni okufakwe ezintanjeni ezihlukanisiwe ukulungisa ibanga phakathi kwezintambo ezihlukanisiwe, ukuze kuvinjwe izintambo ukuthi zingashayi zodwa, cindezela ukudlidliza komoya kanye nokudlidliza kwegebe elingaphansi.Isikhala sivamise ukufakwa phakathi nendawo, futhi esisodwa sifakwa ngesikhawu esingama-50-60m.Izinti ze-spacer ezihlukanisa kabili, ezihlukene ezine, ezihlukene eziyisithupha, neziyisishiyagalombili, uma kuqhathaniswa nobukhulu bokudlidliza bentambo ehlukanisiwe ngemva kokufaka i-spacer rod futhi ngaphandle kwe-spacer rod, izintambo ezimbili ezihlukene zehliswa ngo-50% , futhi izintambo ezine ezihlukene zehliswa ngo-87% no-90%.
Isidingo esiyinhloko se-spacer ukuthi i-clamp kufanele ibe nokubamba okwanele futhi akufanele ikhululeke ngesikhathi sokusebenza isikhathi eside, futhi amandla wonke kufanele akwazi ukumelana namandla amaphakathi ocingo ngalunye oluhlukanisiwe lapho ulayini ufinyezwa futhi ukhathele ngaphansi. ukudlidliza kwesikhathi eside.I-spacer ingahlukaniswa ngezigaba ezimbili: i-damping kanye ne-rigidity mayelana nokusebenza.I-spacer edambisayo ishunyekwe ngephedi yenjoloba engagugi ezingxenyeni zayo ezihambayo, futhi isebenzisa ukumanzisa kwephedi yenjoloba ukuze idle amandla okudlidliza wekhondakta, ngaleyo ndlela ikhiqize umthelela odambisayo ekudlidlizeni komqhubi..Izikhala eziqinile ezingenawo amaphedi enjoloba anjalo ngokuvamile zisetshenziswa ezindaweni lapho ukudlidliza kungelula ukwenzeka khona noma kuma-jumper spacers ngenxa yokusebenza kabi kokumuncwa kokudlidliza.
I-spacer edambisayo iyisikhala esiguquguqukayo noma esiqinile esinganciphisa ukudlidliza komoya noma ukudlidliza kwegebe elingaphansi kwe-conductor ehlukanisiwe.ulayini wezwe lami ongu-500kV wamukela uhlaka lwekhondatha oluhlukene kane.I-spacer iyona efaka kakhulu esakhiweni socingo oluhlukanisiwe.Imisebenzi eyisisekelo ye-spacer yilezi: ukuvimbela ukushaywa phakathi kwezintambo, ukucindezela ukudlidliza komoya kanye nokudlidliza kwegebe elingaphansi.Okusetshenziswa kakhulu i-spacer edambisayo, enokusebenza okungcono kokumunca ukudlidliza kune-spacer eqinile.Ngakho-ke, ukuhlolwa kobuningi bokusebenza kokumunca ukudlidliza kwe-spacer's damping sekube ukhiye wokucwaninga, ukuklama, ukukhiqiza nokukhethwa kwesikhala esimanzisa.

Imingcele yezobuchwepheshe

Izici zomkhiqizo kanye nenzuzo

1. I-spacer edambisayo kanye ne-spacer engancibilikisi.Isici se-spacer sohlobo olumanzi ukuthi irabha isetshenziswa njengento emanzisa endaweni ehlanganyelwayo yesikhala ukuze idle amandla okudlidliza ocingo futhi ikhiqize umthelela odambisayo ekudlidlizeni kocingo.Ngakho-ke, lolu hlobo lwe-spacer lufanele zonke izifunda.Kodwa-ke, uma kucatshangelwa umnotho wezintambo zokudlulisa amandla, lolu hlobo lwesikhala lusetshenziswa kakhulu emigqeni ezindaweni lapho amakhondatha ejwayele ukudlidliza.I-spacer engancibilikisiwe inokumunca kahle kokushaqeka futhi ingasetshenziswa emigqeni esezindaweni lapho ukudlidliza kungelula ukwenzeka khona noma kusetshenziswe njenge-jumper spacer.
2. Amakhondatha ahlukanisiwe amabili, amane noma ngaphezulu asetshenziswa kukhondatha wesigaba ngasinye wemigqa yokudlulisa ye-EHV yamabanga amade kanye nomthamo omkhulu.Njengamanje, izintambo zikagesi ezingu-220KV kanye ne-330KV zisebenzisa amakhondatha ahlukene kabili, izintambo zikagesi ezingu-500KV zisebenzisa amakhondatha ahlukene kathathu nahlukene kane, kanti izintambo zokudlulisa amandla kagesi aphezulu kakhulu ezinama-voltage angaphezu kuka-500KV zisebenzisa amakhondatha ahlukene ayisithupha nangaphezulu.Ukuze kuqinisekiswe ukuthi ibanga eliphakathi kwamahhanisi ezintambo ezihlukanisiwe lihlala lingashintshile ukuze lihlangabezane nokusebenza kukagesi, kuncishiswe ukuthambekela okungaba khona kwendawo, futhi esimweni sokujikeleza okufushane, amandla kazibuthe kagesi ngeke akhiqizwe phakathi kwamahhanisi ezintambo, okubangela ukukhangana. kanye nokushayisana, noma ngisho noma ukungqubuzana okusheshayo okuhehayo kubangelwe, kodwa ngemva kokuba ingozi isiqediwe Ngokushesha ingabuyela esimweni esivamile, ngaleyo ndlela ama-spacer rod afakwa ebangeni elithile endaweni.Ukufakwa kwama-spacer rod nakho kungadlala indima ethile ekuvimbeni ukudlidliza kwe-spa sesibili kanye nokudlidliza komoya.

Isimiso somkhiqizo

Umgomo wokusebenza we-spacer yokudambisa:
ukudlidliza kocingo okubangelwa umoya kanye nokudlidliza kwegebe elingaphansi elibangelwa umoya onamandla kuzobangela ukukhathala kocingo, futhi ukuxega kwe-fastener kuzobangela ukuba ucingo lugqoke.Izintambo ezihlukene zisebenzisa ama-spacers ekusebenzeni okuzinzile kwe-electromechanical.I-spacer edambisayo iwukusebenzisa ukunwebeka kwento yenjoloba ukuze ithole ukuqina okudingekayo ukuze ibe nokuhamba okwanele kuyilapho igcina izilinganiso zejiyomethri zocingo oluhlukanisiwe.Sebenzisa i-viscosity yerabha ukumunca amandla anele ngaphansi kwengcindezi eshintshanayo ukuze ufinyelele inhloso yokucindezela ukudlidliza komoya.
Ukusebenza kokumanzisa kwesikhala esimanzi kuhlobene ne-coefficient encibilikayo yezinto zenjoloba.Kodwa-ke, umthelela wokudambisa wento yerabha usondelene kakhulu nesakhiwo kanye nesimo sokusebenzisa se-spacer.Ukusebenza kwe-damping kuyipharamitha eyinhloko yokucwaninga nokuklama ama-spacers amnyama.Izici zokumunca ukudlidliza nokuqina kwezinhlobo ezahlukene zezikhala ezimanzi zingalinganiswa futhi ziqhathaniswe ngokuhlola ukuqina kwazo kanye nokusebenzisa amandla.
Umgomo wokuhlola
yesikhala esimanzisa amanzi: Usekelo lwentambo yosekelo lwe-spacer edambisayo luxhunywe nesilayidi sethebula lokudlidliza elilingiswayo ukuze kwakhe umshini wesilayidi se-rocker, futhi ukudlidliza kwesilayida kusetshenziswa ukulingisa isimo sokusebenza sesikhala esimanzi phezu kwekhanda. ucingo.Hlola ulayini oyiluphu wenduku yesikhala esimanzi phezu kwentambo engaphezulu ukuze usekele i-amplitude yomugqa wokusekela oshintsha ngamandla angaphandle.Indawo evalwe yilo mugqa weluphu ukulahleka kwamandla kwamasonto onke.Ukuqina okumaphakathi kubalwa kusukela kumandla aphezulu angaphandle kanye ne-amplitude.
I-anti-dancing mechanism ye-clamp rotary spacer:
i-ice coating yocingo olulodwa kanye nocingo oluhlukanisiwe kuhluke kakhulu.I-axis yolayini wokudlulisela ngokuvamile ineqhwa futhi ibheke ohlangothini olubheke umoya.Ngemuva kokuthi umqhubi embozwe ngeqhwa, ukungalingani kwenqwaba kuzosonteka ku-axis yayo.Umumo we-cross-sectional we-conductor oyi-iced uba umfaniswano phakathi nenqubo yokusonteka okuqhubekayo nokumbozwa kweqhwa.Inomphumela wokucindezela ukugeleza kocingo.Ama-conductor ahlukanisiwe anezikhala ngezikhathi ezithile ukuze alungise ama-sub-conductor, ukuze ama-sub-conductor angakwazi ukuzungezisa ngokufanele eduze kwama-spacer rods.Ngesikhathi esifanayo, ngenxa yokuxhumeka okuhleliwe, ukuqina kwe-torsional komqhubi we-sub-gauge omfushane kuyanda.I-sub-conductor ye-sub-gep idinga i-torque enkulu emile ukuze ihlehliswe, futhi kunzima ku-conductor ukuzungeza i-eksisi yayo.I-torsion coefficient yentambo ehlukanisiwe inkulu kakhulu kunaleyo yocingo olulodwa, futhi i-icing engalingani ibucayi kakhulu, ngakho-ke intambo ehlukanisiwe ingase igibele kunocingo olulodwa.
Umgomo wokuvikela wokudansa we-wire clamp rotary spacer: i-rotatable clamp iwukhiye wokuvikela ngokumelene nokudansa.Uma ama-sub-conductor ehlanganiswe nama-spacers, uhhafu wama-sub-conductor ungazungezisa phakathi kwebanga elithile.Ngisho nasendabeni ye-icing, amakhondaktha angaphinda asebenzise i-eccentric mass embozwe yiqhwa futhi embozwe yiqhwa ukuze asonte, futhi akhe ngokusonta ezungeze izimbazo zawo Ngokulinganayo ayindilinga ngoqweqwe lweqhwa.Ukuze kuzuzwe inhloso yokucindezela ukugawula kocingo okumbozwe yiqhwa.
