《企業家日報》 嚴寒高溫全不怕 環宇斷路器河北光伏電站顯“神威”

 嚴寒高溫全不怕 環宇斷路器河北光伏電站顯“神威”

《企業家日報》2018年05月08日
     
四月末的塞外山城宣化,乍暖還寒。  
    迎著呼嘯的山風,環宇電氣河北辦事處的項目回訪技術人員來到了這片充滿生機與希望的大地!汽車沿盤山公路向西南行駛,隔窗遠眺,溝壑林立。美麗的桑干河流水潺潺,偶爾可見古烽火臺巍然聳立。兩小時后,車輛駛達目的地——宣化80MW光伏電站。  
    到達后,環宇回訪工程師受到電站領導的熱情歡迎,并給予了全程配合。這座電站依山而建,2017年11月并網發電,可為冀北電網年提供1.1億度清潔電能。環宇電氣為該項目匯流箱量身定制的光伏專用斷路器,運行平穩受到用戶好評。
   光伏電站系統的電池板采集太陽能發出直流電。經逆變器逆變為交流480V-520V電壓后,需要一臺關鍵設備將逆變后的多支交流電輸送給站內變壓器進行35KV升壓——這臺設備就是交流匯流箱。  
   為防止野外各種小型動物鉆進去釀成相間短路事故,匯流箱通常被做成密閉式。其防護等級可達IP65,環境溫度-25℃-65℃,既要耐高溫,又要承受遠大于日常AC380V的高電壓,加之項目所在山區海拔大都在1000米以上,這對所配置的斷路器要求頗為苛刻。而環宇電氣提供的斷路器產品性能,則完全達到并超過了規定要求。半年多來,環宇產品經受住了客觀環境的考驗,確保了宣化光伏電站的正常發電。
多年來,作為中國電氣行業龍頭企業之一的環宇電氣,針對光伏發電系統的特殊要求,不斷研發出擁有自主知識產權的光伏專用斷路器產品,被廣泛應用于國內各地,并遠銷歐美和大洋洲等發達國家的太陽能光伏發電系統中,為不同光伏發電應用領域提供完善的電氣支持和優質服務。(李光杰)
