The invention discloses a partial discharge localization method based on electro-acoustic joint detection signal propagation delay compensation. The method firstly samples and extracts partial discharge ultra-high frequency electromagnetic waves and ultrasonic acoustic signals, and obtains electromagnetic wave pulses and ultrasonic waves generated by partial discharge sources. Acoustic pulse signal; then extract the propagation delay characteristics of the two signals respectively; take the propagation delay characteristic value of the electromagnetic wave signal as a reference to obtain the relative propagation delay of the ultrasonic signal, and carry out the relative propagation delay under the metal boundary condition. Correction and compensation; then calculate the distance between the partial discharge source and the ultrasonic sensor; repeat the sampling to calculate the distance between the partial discharge source and a single ultrasonic sensor, and use the arithmetic mean value of the distance as the final determined distance between the partial discharge source and the ultrasonic sensor; finally combine The electrical arrangement in the cabinet determines the specific location of the partial discharge source. The positioning method of the present invention can more accurately reflect the exact position of the partial discharge source of the equipment.
