Mwachidule

DR-XGN-24 bokosi-mtundu AC zitsulo chatsekedwa mphete maukonde switchgear ndi m'badwo watsopano wa sulfure hexafluoride katundu masiwichi, amene akhoza kukhazikitsidwa ndi ophwanya dera, kudzipatula masiwichi, thiransifoma panopa, thiransifoma voteji, zomangira mphezi ndi zigawo zina zamagetsi. Kabizinesi yonseyo ndi yotsekeredwa ndi mpweya ndipo ndi yoyenera kugawa magetsi. Ndi switchgear yophatikizika komanso yowonjezera yachitsulo. Ili ndi mawonekedwe a mawonekedwe okongola, kapangidwe kosavuta, kakulidwe kakang'ono, ntchito yosinthika, komanso kulumikizidwa kodalirika.

Izi mphete maukonde nduna ndi oyenera magawo atatu AC 50Hz, oveteredwa voteji 12kV mphete maukonde mphamvu kotunga mphamvu, ndipo chimagwiritsidwa ntchito mu mafakitale ndi wamba maukonde mphete mphete ndi ntchito magetsi otsiriza. Ndizoyenera makamaka kumalo otsatirawa: kugawa magetsi m'madera okhala m'matauni, malo ang'onoang'ono ang'onoang'ono, maofesi osinthika, mafakitale ndi migodi, malo ogulitsira, ma eyapoti, ma subways, tunnels, magetsi opangira mphepo, etc.

Mankhwala mbali zazikulu

◆ Wonjezerani mphamvu ya transformer yayikulu ndikuwongolera mphamvu yamagetsi yamagetsi.

◆ Kupititsa patsogolo mphamvu yotumizira mphamvu ya mizere yogawa ndikuchepetsa chiwerengero cha mizere yogawa.

◆ Onjezani utali wamagetsi wamagetsi apakati.

Mphamvu yamagetsi iyi idayesedwa m'malo ochepa kale. Popemphedwa ndi State Grid Corporation yaku China, mphamvu yamagetsi ya 20kV idakwezedwa moyeserera m'chigawo cha Jiangsu. Tsopano China Southern Power Grid ikukonzekeranso kulimbikitsa voteji ya 20kV ku Guangdong ndi malo ena. Titha kunena kuti pamapeto pake zida za 24kV zidzalamulira msika.
