10kV和20kV开关柜技术与经济分析

10 kV and 20 kV Switchboards Technology and Economic Analysis

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 l 0 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.
