Abstract :
Insulating vegetable oils are fire-resistant and environment-friendly liquid dielectrics. This paper presents a type of nano-modified insulating vegetable oil. The nano-modified insulating vegetable oil was prepared by homogeneous precipitation deposition of ferroferric oxide nano-particles. It was characterized by a laser nano-particle size analyzer. Its electric properties, including AC breakdown voltage, lightning impulse breakdown voltage, volume resistivity, relative permittivity, and dissipation factor were measured. Experiment results show that the ferroferric oxide nano-pariticles with proper content in oil improves the breakdown voltages, volume resistivity, and lightning impulse electrical strength of the insulating vegetable oil significantly.
