低压变压器

2014/8/25 16:25:17点击:

一般来说,低压600V以下变压器成为低压变压器。低压变压器是由初级线圈、次级线圈和铁心(磁芯)构成,通过电磁感应来改变电压的装置。在电器设备和无线电路中,常用作升降电压、匹配阻抗,安全隔离等。

压变压器应为真空铸造,模铸树脂封装,60Hz,F级绝缘
,符合IEC726的规定,并符合所示的容量、电压、相数及结线等要求。低压变压器每一相应有个别的一次及二次绕组,一次侧额定电压上下各有两个2.5%正常电压的全容量分接头
。低压变压器应装在可以隔离、降低振动及噪音的基座上,铁心及线圈应妥加固定以承受线路故障情况下所产生的机械应力,并能承受 16460 精简版 16460 - 6
V2. 0 2002/ 11/ 25 在装运途中所发生的振动及冲击力。 除另有规定者外,低压变压器的阻抗应依IEC 726
。低压变压器的平均噪音等级应不超过IEC 726 所规定的值。
每一干式低压变压器应有适当的端子以容纳所需的一次及二次配线连接。低压变压器可由任何一侧或底部预留电缆入口。
