降低超高压输电线路电晕噪声的对策研究

Study on countermeasures of lowering the EHV transmission line corona noise

从电力金具的选型、设计、生产、运输、安装和优化改造等环节提出了降低超高压输电线路电晕噪声的对策措施。同时,通过对超高压输电线路铁塔可听噪声和金具电晕放电情况的检测,验证优化改造金具的降噪效果,查找金具安装的缺陷和漏洞,为金具制造和设计、预防电晕措施的选择及电力金具的改良、安装和运行等方面提供决策和参考依据。

It presented countermeasures to reduce the EHV transmission line corona noise ,which from the electri- cal gold utensil selection, design, production, transportation, installation and optimization aspects. At the same time ,to verify the noise reduction effect of improving gold utensil and to find the short - comings and gaps of the gold utensil installed by detecting corona discharge and audible noise of the iron towers gold utensil. The study provided decision -making and reference for manufacturing and design of gold utensil,choosing prevention co- rona measures,improvement,installation and operation of electrical gold utensil.
