网络优化资料:
绝缘距离;
对于电压低于500伏的电路,空气间隙大于10毫米,排母排针生产爬电距离大于12毫米,5.12.2电压3。6-40.5kV线路的最小绝缘距离应符合表5的要求;
母线的选择;
样品要求,根据图纸要求,
如果图纸没有要求,中压柜按表6选择。低压柜可根据铜母线安全电流表选择。
母线的标识:
母线应标有不同颜色的热缩套管。如果排母排针怎么连接热缩套管的颜色不能满足要求,可以使用母线专用相序色标,并粘贴在明显的地方。
母线的颜色标识;
三相交流电路;a相为黄色,b相为绿色,c相为红色,n线为浅蓝色,PE线为黄绿色。
DC电路;正极极棕,负极蓝色,接地中性线淡蓝色,母线搭接5.15;
