Abstract
This disclosure relates to methods and systems to reduce high voltage breakdown jitters in liquid dielectric switches. In particular, dielectric liquids have been produced that contain a suspension of nanoparticles and a surfactant to reduce the breakdown jitter. In one embodiment, the suspended nanoparticles are Barium Strontium Titanate (BST) nanoparticles.
Claims19
A method for preparing a dielectric fluid to reduce voltage breakdown jitter in a high voltage spark gap comprising:
- providing the dielectric fluid;
- sparging the dielectric fluid with dry nitrogen;
- adding a plurality of nanoparticles to the dielectric fluid;
- adding a surfactant to the dielectric fluid;
- sonicating the dielectric fluid;
- filtering the dielectric fluid;
- and,
- pressurizing the dielectric fluid.
