220kV SADEX-WEJIGA KU SAABSAN SHARCIGA KOOXDA

BEDDELIHII

Soo koobid

220kV saliid saddex-waji ah oo lagu dhex shubay korantada xakamaynta beddelka waxay keentaa isbeddello waaweyn oo taxane ah oo xagga agabka, farsamada, iyo dhismaha.Waa sifada dhismaha cufan,
miisaan yar, waxtar sare leh, lumis hoose, buuq yar, iyo isku halaynta waxqabadka.Alaabtu waxay yarayn kartaa khasaaraha wayn ee khadka iyo kharashaadka hawlgalka waxayna kordhin kartaa waxtarka dhaqaale ee kala duwan.
Alaabtu waxay la kulmeysaa heerarka qaranka ee soo socda: GB1094.1-2013 Transformers Power Qaybta 1: Guud;GB1094.2-2013
Korontada korantada Qaybta 2: Kor u kaca heerkulka;GB1094.3-2003 Transformers Power Qaybta 3: Heerarka dahaarka, tijaabooyinka korontada ku shaqeeya iyo nadiifinta dibadda ee hawada;GB1094.5-2003 Transformers Power Qaybta 5: Kartida u adkeysiga wareegga gaaban;
GB/T6451-2015 Qeexidda iyo shuruudaha farsamada ee saddex weji oo saliidda beddelka tamarta ah.

Xusuusnow 1Transformers oo leh awood lagu qiimeeyay in ka yar 31500 kVA iyo isku-darka korantada ayaa sidoo kale la bixin karaa sida loogu baahdo.
Xusuusin 2 Transformers leh koronto yar oo ah 35 kV ama 38.5 kV sidoo kale waa la bixin karaa sida loo baahdo.
Xusuusin 3 Qaab-dhismeedka aan kala go'a lahayn ayaa la door bidaa.Haddii ay jirto wax shuruud ah oo loo baahan yahay in lagu shaqeeyo, xirayaasha-hoosaadka ayaa la dejin karaa.
Xusuusin 4 Marka celceliska xadiga xamuulka sanadlaha ah ee transformer-ku uu u dhexeeyo 45% iyo 50%, hufnaanta hawleed ee ugu badan waxa lagu heli karaa iyadoo la isticmaalayo qiimaha lumay shaxda.
