產品名稱: 630kVA12脈波整流變壓器

 

產品特點

產品采用高效電磁優化設計,性價比高,效率高。合理布局散熱風道,確保產品安全、高效運行及更長的使用壽命,具有非常高的安全及阻燃性能,動熱穩定好,抗熱沖擊能力強,以及獨特的線圈結構和強場計算,幾乎無局放產生,壽命期后可輕易將絕緣材料和繞組導體分離回收利用,不污染環境。

線圈采用箔繞,層間H級絕緣材料,并經VPI真空加壓設備浸漬H級絕緣漆,多次烘焙并高溫固化。線圈結構機械強度高,風道結構合理布置均勻,散熱條件好,負載損耗小。
    鐵芯材料選用優質高導磁取向薄硅鋼片疊裝,勵磁電流小,空載損耗??;采用直接在鐵芯柱上繞制工藝,結構合理緊奏,體積小、重量輕、噪音低以及附加雜散損耗小。鐵芯表面經特殊工藝處理,鐵芯由穿心螺桿適度夾緊,上、下夾件由拉板連接并通過上下減震墊塊頂壓線圈固定為一體,進一步有效減少產品震動和降低噪音。
