随着工、农业建设的迅速发展以及科学技术的不断进步,高压输电线路和变电站将迅速增加,电压等级也会越来越高,这就不可避免地会给广播、电视的接收产生越来越严重的无线电干扰。为保证良好接收,必须制定出相应的干扰限额标准,以便有章可循。然而,我国目前还没有这方面的标准。国际无线电干扰特别委员会C分会(C.I.S.P.R/C)所提出的《架空电力线和高压设备干扰手册》(第二草案),对我们制定干扰限额标准是有参考价值的,现将其第8节“干扰限额”译载于下。文中涉及到其他章节的内容,因为对领会本节内容无直接影响,故大部分不作说明。
With the rapid development of industry and agriculture and the continuous improvement of science and technology, the high-voltage transmission lines and substations will increase rapidly and the voltage level will be higher and higher, which will inevitably lead to the increasingly serious reception of radio and television Radio interference. In order to ensure good reception, the corresponding interference limit standard must be worked out so that there is a rule to follow. However, our country does not yet have the standard in this respect. The Manual on Interference with Overhead Power Lines and High Voltage Equipment (Draft No. 2) proposed by CISPR C (Cth 2) is of reference value to us in setting the interference ceiling standard. Now, Section 8 “Interference Limits ”in the next translation. The content of other chapters in the text, because it has no direct influence on comprehension of the contents of this section, so most do not explain.
