    低壓變壓器

    2014/8/25 16:25:17點擊:

    一般來說,低壓600V以下變壓器成為低壓變壓器。低壓變壓器是由初級線圈、次級線圈和鐵心(磁芯)構成,通過電磁感應來改變電壓的裝置。在電器設備和無線電路中,常用作升降電壓、匹配阻抗,安全隔離等。

    壓變壓器應為真空鑄造,模鑄樹脂封裝,60Hz,F級絕緣
    ,符合IEC726的規定,并符合所示的容量、電壓、相數及結線等要求。低壓變壓器每一相應有個別的一次及二次繞組,一次側額定電壓上下各有兩個2.5%正常電壓的全容量分接頭
    。低壓變壓器應裝在可以隔離、降低振動及噪音的基座上,鐵心及線圈應妥加固定以承受線路故障情況下所產生的機械應力,并能承受 16460 精簡版 16460 - 6
    V2. 0 2002/ 11/ 25 在裝運途中所發生的振動及沖擊力。 除另有規定者外,低壓變壓器的阻抗應依IEC 726
    。低壓變壓器的平均噪音等級應不超過IEC 726 所規定的值。
    每一干式低壓變壓器應有適當的端子以容納所需的一次及二次配線連接。低壓變壓器可由任何一側或底部預留電纜入口。
