Split conductor ion flow space distribution measuring method and device

The invention discloses a split conductor ion flow space distribution measuring method and device in the technical field of high-pressure gas discharge measurement. The device comprises a metal bracket, a cylindrical corona cage, a shielding cable, a signal acquisition card, a computer, a first hanging disc, a second hanging disc, a first composite insulator, a second composite insulator, a first tightener, a second tightener, an insulating screw, a Wilson plate, a sampling resistor and an earth wire. Through the method and the device, measurement of an ion flow distribution condition around adjacent split conductors is realized, and a verification means is provided for theoretical research of ground electric field effect, corona loss and the like of split conductor corona discharge.
