%X 现行相关标准对直流架空输电线路与短波无线电收信台的防护间距尚无规定，但该防护间距的取值问题在直流线路设计中经常遇到并亟需解决。根据直流线路的无线电干扰特性及水平、短波收信台的工作特性及电磁兼容能力，提出直流线路的防护间距值可根据直流线路无线电干扰水平参照交流线路考虑。基于防护间距计算值，结合相关科研成果及工程实践经验，给出了±400 kV~±800 kV直流线路与短波收信台的防护间距值，为直流线路对短波收信台干扰影响的防护设计及制订相关标准提供了技术支撑。<br />
The current relevant standards have no regulations on the protection distance between DC over-head transmission lines and short-wave radio receiver, but the value of the protection distance is often encountered in the design of DC lines and needs to be solved urgently. According to the radio interference characteristics and level of the DC lines, the working characteristics of the short-wave receiver and the electromagnetic compatibility capability, it is proposed that the protection interval value of the DC line can be considered based on the radio interference level of the DC line with ref-erence to the AC line. Based on the calculated value of the protection distance, combined with rele-vant scientific research results and engineering practice experience, the protection distance value of ±400 kV~±800 kV DC line and short-wave receiver is given. It has provided technical support for the protection design of DC lines interference to short-wave receiver interference and the revision of relevant standards.
