摘要
在直流输电线路对市话通信系统影响的防护设计中,目前对危险影响的电压允许值、干扰影响的杂音纵电动势允许值界定差异较大,根据影响机理、国际国内标准及最新研究成果,提出了规范化建议,为正在编制的电力行业标准DL/T5340《直流输电线路对电信线路影响防护设计规程》提供了依据。
At present,allowable values of voltage in dangerous effect and longitudinal electromotive force in interference effect are practically uncertain in the anti-interference design of DC power transmission line for local telephone system.According to the interference principle,national and international standards and latest research results,standardized suggestions are promoted,which could provide the basis for compiling power industry standard DL/T5340：＂Technical Code for the Design of Telecommunication Lines Against Danger Effects from DC Power Transmission Lines.＂
