摘　　要：针对我国高压电机设备效率低问题,提出并分析了高压交流调速技术,得出直接高-高型变换高压变频调速技术是最先进的高效节能技术,并结合具体应用计算分析了其高节能效率。In this paper, we pointed out the problem of low eflqciency of high - voltage electric motor in China. The adjusting speed on high - voltage electric motor by the frequency - conversion is introduced. The direct “high voltage -high voltage”conversion of the adjusting speed on high - voltage electric motor system by frequency - conversion is the most advanced and high - efficiency way. In the end, its high - efficiency is calculated and analysed by examples.

关 键 词：高压 变频 调速 节能
