本文介绍中国第一条从北京房山变电站至昌平变电站全长83公里的500kV紧凑型输电线路在投运前、后所做的多次试验的情况.试验结果表明所有电气参数完全符合设计要求.%The paper deals with the tests on the first 500 kV compact transmission line. The transmission line stretches from Fangshan Substation to Changping Substation nearby Beijing with a length of 83 km. In order to investigate the characteristics of the transmission line, many tests were performed on the line before and after its operation. The results indicate that all electrical parameters are perfectly identical to the design.
