Abstract: Ngokuphuculwa okuqhubekayo kwemigangatho yokuphila kwabantu, imfuno yabantu yombane nayo iphezulu kwaye iphezulu, nayo yakhuthaza uphuhliso olukhawulezayo lweshishini lamandla, isantya sokusekwa kwegridi. Ngelo xesha, i-State Grid iphinda ifake ukubaluleka ngakumbi kuphuhliso lwe-UHV. Iintambo zothumelo ze-Uhv zinokuqonda umthamo omkhulu kunye nomgama omde wothumelo, zinciphise iindleko zothumelo kunye nelahleko yeentambo, kwaye zibe neenzuzo ezibalulekileyo kwezoqoqosho. Nangona kunjalo, ngenxa yommandla omkhulu kunye nokusingqongileyo okukhethekileyo kwejografi, kunzima ukwakha nokugcina iintambo zothumelo lwe-UHV, ngakumbi impembelelo yomoya kwiintambo zothumelo ze-UHV ze-500KV. Ngoko ke, ukuze kwenziwe uphuhliso lwexesha elide leentambo zothumelo lwe-500KV UHV, kuyimfuneko ukuhlalutya isiphene sokutenxa emoyeni, ukukhuthaza uphuhliso lwexesha elide olusempilweni lwemigca yosulelo lwe-500KV UHV, kunye nokuhlangabezana nemfuno yabantu yamandla ombane. Amagama aphambili: 500KV; Ukuhanjiswa kwamandla ombane aphezulu kakhulu; impazamo yokutenxa umoya; Amanyathelo; Okwangoku, i-wind offset fault ye-500KV i-ultra-high-high-volta transmission lines ibe yenye yezinto eziphambili ezichaphazela ukusebenza okukhuselekileyo nokuzinzileyo kwemigca. Xa kuthelekiswa neengozi zombane kunye nomonakalo weentaka, i-wind bias inokubangela umonakalo. Nje ukuba impazamo yokucima umoya yenzekile, kulula ukubangela ukuvalwa okungalindelekanga kweentambo zothumelo, ingakumbi iintambo zothumelo lwamandla ombane aphezulu ngaphezulu kwe-500 kV. Isiphoso sokupheliswa komoya asichaphazeli kakhulu ukuthembeka konikezelo lwamandla kuphela, kodwa kuzisa ilahleko enkulu yezoqoqosho kumashishini obonelelo ngombane.

Isishwankathelo seempazamo zokunxaxha emoyeni

Kwimozulu enomoya, umgama phakathi kwabaqhubi abaphilayo bomgca wothumelo kunye neepayiloni, iipali zebhulorho, iintambo zokutsala, ezinye iikhondaktha zomzila wothumelo, kunye nemithi ekufutshane kunye nezakhiwo zincinci kakhulu. Ngenxa yoko, umgca wothumelo unokubangela iimpazamo. Ukuba ukutenxa komoya akupheliswanga ngexesha, ingozi iya kwandiswa. Kukho ubukhulu becala ezi ntlobo zilandelayo zokuphambuka komoya: ii-conductor zentambo zothumelo zibekwe kwipaseji emacaleni omabini esakhiwo okanye kwithambeka elikufutshane okanye ihlathi; Kukho iingxaki zokuhambisa amanzi ebhulorho kunye ne-drainage yenqaba kwi-tension tower. I-insulator kwinqaba ikhupha inqaba okanye intambo. Kwiminyaka yakutshanje, ngotshintsho lwemo engqongileyo kunye nemozulu kunye nomoya onamandla, iintambo zothumelo zihlala zineempazamo zokutenxa komoya. Ngoko ke, kuyimfuneko ukuqinisa ukukhuselwa kwempazamo ukuqinisekisa ukusebenza okuzinzile kwenkqubo yamandla.
