Cable distributed partial discharge positioning data acquisition method

The invention relates to a cable distributed partial discharge positioning data acquisition method. The method comprises the following steps: S1, connecting a monitoring terminal with a satellite; s2, monitoring terminal signal data acquisition; s3, analyzing and calculating signals of the monitoring terminal; s4, delay triggering time signal acquisition; and S5, positioning a partial discharge point. The method is simple and convenient to operate, and synchronous measurement of a plurality of monitoring points can be realized by relying on a wireless communication network constructed on site; according to the invention, the data transmission quantity is small, the data quantity can be greatly compressed to 10%, the partial discharge positioning of a large-length cable (greater than 1km) can be realized, the cable insulation defect positioning time is reduced, the single data acquisition quantity is smaller, the simultaneous time of field measurement is shorter, and the operation efficiency is obviously impro
