 <description><![CDATA[没烧真是奇迹！赶快换变压器吧。电缆加大要将近4倍才行！很危险！如果功率因数低的话，可以增加无功补偿降低变压器选型电流标准。]]></description>

 <description><![CDATA[经验公式,一般人我不考诉的:电流=线径*2.5
即150*2.5=750A最大只能承受到750

500000VA/(1.732*400V)=721A
[/quote]
我計算出來的是近760A的電流·～～！]]></description>

 <description><![CDATA[电缆太小了，150的电缆最多只有300~400A的电流，严重过载了。就是裸线也不够了，除非你是超导线。]]></description>
