前言对于高压输电线路无线电干扰问题,国内外均做了大量的工作。本文仅就葛洲坝工程无线电干扰研究过程中收集到的国内外资料作一简要综述,其中亦收集了一些葛洲坝工程的试验成果。一、无线电干扰的定义无线电干扰(ra(li、)1 ntcrference,缩写为Rl)或称无线电噪声(RN),其定义为“在无线电频带内任何不希望出现的干扰,比如任何传输通道或装置中不希望出现的各种电波”’]。理论和实测表明,高压输电线路对外界发射无
Preface For radio interference on HV transmission lines, a great deal of work has been done at home and abroad. In this paper, only a brief overview of the domestic and foreign data collected during the study on the radio interference of the Gezhouba Project has been made. Some of the test results of the Gezhouba Project have also been collected. I. DEFINITION OF RADIO INTERFERENCE Radio interference (ra (li,) 1 ntcrference, abbreviated as Rl), or radio noise (RN), is defined as any undesired interference in the radio frequency band, such as any transmission channel or The device does not want to appear a variety of radio waves. Theoretical and practical tests show that high-voltage transmission lines have no emission to the outside world
