摘　　要：利用所建立的局部放电光学测量装置 ,研究了几种典型放电源的光脉冲信号在不同媒质中的传播衰减特性 ;比较了不同放电类型光脉冲信号与电信号之间的关系。实验结果表明 ,放电产生的光信号与视在放电电荷量及放电能量有关。光脉冲测量法已被用于防爆电机局部放电的测量。This paper reports on optical pulse detection of partial discharge(PD). A measuring system of optical discharge measurement was established. The feature of optical signal transmission and attenuation in different media is discussed. In this paper, the relationship between optical and electrical signals of discharge is compared. The results indicate that the intensity of optical signals corresponds both with the amplitudes of PD and with the discharge energy. This optical method has been used to detect the discharge in the explosion-proof motors.
