摘要
试验研究了绝缘子放电声发射波的产生及传播的基本规律,探讨了各种绝缘子放电声发射波的传播路径,讨论了声发射波在绝缘子本体和空气中的传播速度、反射和折射规律。试验研究了绝缘子放电声发射波的方向性及其在空气中的衰减特性,发现声发射波具有明显的方向性,并且呈快速下降的指数规律衰减。
The basic law of producing and spreading of insulator discharge AE wave is researched by experiments in this paper. Spreading route, speed, reflection and refraction of AE wave, in insulators and air, are explored. Directionality and decay characteristic of AE wave from insulators in air are studied. It＇s found that AE wave has distinct directionality and decay fast by the exponent law.
