XGN15-24 BOX-TYPE YAKAKONZWA AC METAL-ENCLOSED SWITCHGEAR
Overview
DR-XGN-24 bhokisi-mhando AC simbi yakavharwa mhete network switchgear chizvarwa chitsva chesarufa hexafluoride load switch, iyo inogona kugadziridzwa nemagetsi mabreaker, ega ega, ega ega anoshandura, voltage transformers, mheni zvinosunga uye zvimwe zvikamu zvemagetsi. Iyo yese cabinet ndeye air-insulated uye inokodzera kugovera magetsi otomatiki. Iyo compact uye inowedzera simbi-yakavharirwa switchgear. Iyo ine hunhu hwekutaridzika kwakanaka, chimiro chakareruka, diki saizi, inochinjika kushanda, uye yakavimbika inopindirana.
Iyi mhete inetiweki kabati inokodzera matatu-chikamu AC 50Hz, yakayerwa voltage 12kV mhete network magetsi emagetsi system, uye inoshandiswa zvakanyanya mumaindasitiri uye evagari tambo mhete network nemapurojekiti emagetsi emagetsi. Iyo inonyanya kukodzera kune dzinotevera nzvimbo: kugovera magetsi munzvimbo dzekugara dzemudhorobha, zviteshi zvidiki zvechipiri, kushandura mahofisi, maindasitiri nemabhizinesi emigodhi, zvitoro zvezvitoro, nhandare dzendege, subways, tunnel, kugadzirwa kwemagetsi emhepo, nezvimwe.
Product main features
◆ Wedzera simba guru rekushandura uye uvandudze simba rekupa simba rechiteshi.
◆ Kuvandudza simba rekufambisa simba remitsara yekugovera uye kuderedza nhamba yemitsara yekugovera.
◆Kuwedzera magetsi emagetsi emagetsi epakati.
Iyi voltage level yaive yekuyedza munzvimbo diki kare. Nekukumbirwa neState Grid Corporation yeChina, chiyero chevoltage 20kV chakasimudzirwa pahwaro hwekuyedza muPurovhinzi yeJiangsu. Ikozvino China Southern Power Grid iri kugadzirirawo kusimudzira 20kV voltage level muGuangdong nedzimwe nzvimbo. Zvinogona kufanotaurwa kuti pakupedzisira 24kV michina ichatonga pamusika.
