Generating high voltages with a plasma coil transformer

摘要

A novel prototype plasma coil based dry-type transformer has been built and used to create 75kVpeak impulse voltages from a 40kVd.c. capacitor bank. This device uses an air-cored coil ofexploding wire to produce a high voltage output from a copper magnet wire winding. Effectiveinsulation coordination has been developed for the unique requirements of this device. Preliminarytheories behind the mechanisms which drive this device are presented. Future improvements arenoted, which are planned to allow voltages of several hundred kilovolts to be generated.
