摘要
介绍了10kV和20kV开关柜技术条件和参数的差别,由于20kV元器件尺寸比10kV的略有放大,导致开关柜尺寸也有所放大,需采取相应技术措施来完善。虽然20kV开关柜比10kV开关柜价格稍高,但供电能力成倍增加,通过性价比的分析和比较,生产20kV开关柜经济效益是很好的。
Introduction was made to the differences of technical conditions and parameters between 10 kV and 20 kV switchboards. Since dimensions of 20 kV components were a little bit enlarged than that of l0 kV, causing that the dimensions of switchboards were also somewhat enlarged, the corresponding technical measure was adopted to complete. Although the price of 20 kV switchboards was a little bit higher than that of 10 kV, the power supply capacity increased doubly. Via performance-cost ratio analysis and comparison, to produce 20 kV switchboards is very good in economic efficiency.
