摘要
本文就高压架空送电线路设计中，按实际工程情况计算短波无线电收信台所需防护间距时，环境噪声电平取值问题进行了初步探讨。提出为避免不必要的浪费，在一般工程设计中，环境噪声９０％电平值取１５－２０ｄＢ是可行的。当然，最好根据工程具体情况进行计算，并给出了计算方祛。
The level value for environmental noise when calculating the necessary protective space of shortwave wireless receiver in the design of high voltage trolly wire was discussed. l5-20dB of level value for 90% environmental noise was considered proper for the purpose of saving, but the best value should be based on the practical situation, and the calculation method was presented in this paper.
