新一代500千伏交流输变电设备

A New Generation of 500kV Transmission Equipments

输变电设备的制造和供应能力是制约我国电网发展的因素。改革开放十年以来,我国的电工制造部门通过自强自立和引进消化国外先进技术,产品质量不断提高。本文通过对8种主要产品的更新换代过程的介绍和质量分析,展示了国产设备的技术经济指标和质量水平正逐渐接近国际水平。

The first 500kV substations established with complete domestic developed set of transmission equipments were put in service in 1983. Since 1980s a series of foreign technology licences in this field had been brought in.In the mean time a new generation of 500kV transmission equipments including domestic modified designs and foriegn types had emerged with proved better performances and relative low losses, vibrations, noises as well. This paper also introduces the main aspects for further improvement of individual elements.
