Vehicle-mounted transformer substation partial discharge positioning system

The utility model provides a vehicle-mounted transformer substation partial discharge positioning system. Four radio frequency electromagnetic wave sensors are installed on a vehicle to receive electromagnetic wave signals emitted by partial discharge points, signal conditioning circuits carry out amplifying and filtering processing on the received signals, a high speed sampling unit carries out synchronous acquisition on four paths of output signals, data is outputted to a data processing and analysis unit to calculate start times that four radio frequency omnidirectional sensors receive ultra high frequency signals radiated by a same discharge source in real time, equations are listed based on a time difference of the received four signals, a direction angle and a radial distance of a discharge signal are solved, and the positioning is realized. The system can carry out partial discharge detection and positioning on all high voltage equipment in a transformer substation is facilitated, the cost of equipment
