GIS equipment breakdown fault positioning system and method based on transient magnetic field

The invention relates to a GIS equipment breakdown fault positioning system and method based on a transient magnetic field, and the system comprises a plurality of magnetic field sensing devices which are used for detecting transient magnetic field signals generated during breakdown faults, and storing and transmitting the transient magnetic field signals exceeding a threshold value; the wireless signal relay device is used for receiving and collecting the transient magnetic field signals transmitted by the magnetic field sensing device and outputting the transient magnetic field signals; the data processing server is used for receiving and analyzing the transient magnetic field signal, judging the position of a breakdown fault and displaying detected data and a judgment result; the plurality of magnetic field sensing devices are dispersedly placed on the surface of the GIS equipment; the wireless signal relay device is connected with the data processing server through a network cable; transient magnetic fiel
