XGN15-24 BOX-HOM FIXED AC METAL-ENCLOSED SWITCHGEAR
Txheej txheem cej luam
DR-XGN-24 lub thawv-hom AC hlau kaw lub nplhaib network switchgear yog lub cim tshiab ntawm sulfur hexafluoride load keyboards, uas tuaj yeem teeb tsa nrog cov hluav taws xob hluav taws xob, cais cov keyboards, tam sim no transformers, voltage transformers, xob laim ntes thiab lwm yam khoom siv hluav taws xob. Tag nrho cov txee yog cua-insulated thiab tsim nyog rau kev faib hluav taws xob automation. Nws yog ib qho compact thiab expandable hlau-enclosed switchgear. Nws muaj cov yam ntxwv zoo nkauj, qauv yooj yim, me me, kev ua haujlwm yooj yim, thiab txhim khu kev qha interlocking.
Lub nplhaib network no yog tsim rau peb-theem AC 50Hz, nyob voltage 12kV nplhaib network fais fab mov system, thiab yog dav siv nyob rau hauv industrial thiab civil cable nplhaib tes hauj lwm thiab fais fab mov davhlau ya nyob twg tej yaam num. Nws yog tshwj xeeb tshaj yog haum rau cov chaw hauv qab no: hluav taws xob faib hauv nroog thaj chaw, me me substations, hloov chaw ua haujlwm, kev lag luam thiab mining lag luam, khw malls, tshav dav hlau, subways, tunnels, cua zog tsim, thiab lwm yam.
Cov khoom tseem ceeb nta
◆ Ua kom lub ntsiab transformer muaj peev xwm thiab txhim kho lub zog muaj peev xwm ntawm lub substation.
◆ Txhim kho lub zog xa hluav taws xob muaj peev xwm ntawm cov kab xa tawm thiab txo cov kab xa tawm.
◆ Ua kom lub zog hluav taws xob ntau dua ntawm cov kab nruab nrab voltage.
Qhov ntsuas hluav taws xob no tau sim khiav hauv thaj chaw me me ua ntej. Raws li qhov kev thov ntawm Lub Xeev Grid Corporation ntawm Tuam Tshoj, 20kV voltage theem tau nce qib ntawm kev sim hauv xeev Jiangsu. Tam sim no Tuam Tshoj Southern Power Grid tseem tab tom npaj los txhawb 20kV voltage theem hauv Guangdong thiab lwm qhov chaw. Nws tuaj yeem kwv yees tias thaum kawg 24kV cov cuab yeej yuav ua tus thawj coj hauv khw.
