CN110853844A 一种输电线路电晕可听噪声的降噪方法及装置 无效 - 驳回

一种输电线路电晕可听噪声的降噪方法及装置
摘要：
本申请公开了一种输电线路电晕可听噪声的降噪方法及装置，包括对输电导线进行预处理，以去除所述输电导线表面的污垢；在预处理后的所述输电导线的表面喷涂亲水性涂料；对所述输电导线表面喷涂的亲水性涂料进行固化处理；判断所述输电导线表面喷涂的亲水性涂料的厚度、外观以及接触角是否达到要求；若所述输电导线表面喷涂的亲水性涂料的厚度、外观以及接触角的任意一项未达到要求，则重新喷涂亲水性涂料。该降噪方法能够有效降低输电线路的电晕可听噪声，减少对输电走廊周边环境的噪声污染，并且简单易行、易于推广。
摘要（英）：

The invention discloses a noise reduction method and device for corona audible noise of a power transmission line. The method comprises steps of preprocessing a power transmission wire to remove dirton a surface of the power transmission wire; spraying hydrophilic coating on the surface of the pretreated power transmission wire; carrying out curing treatment of the hydrophilic coating sprayed onthe surface of the power transmission wire; judging whether the thickness, the appearance and a contact angle of the hydrophilic coating sprayed on the surface of the power transmission wire meet therequirements or not; if not, the hydrophilic coating is sprayed again. The method is advantaged in that the method can effectively reduce the corona audible noise of the power transmission line, reduces noise pollution to the surrounding environment of a power transmission corridor, is simple and easy to implement, and is easy to popularize.
