Calculation of Electric Field of Fluorocarbons in Gas-Liquid Mixed State

Electric Field, Fluorocarbons, Gas-Liquid Mixed State

Fluorocarbon liquid compound has strong insulation, strong heat dissipation, non-flammable and good chemical stability. It has broad application prospects in indoor substation power transformers, capacitors, compact converter valves and other equipment. And it can achieve an effective combination of efficient heat dissipation, reducing system volume and weight, and improving operational reliability. When fluorocarbon is used as the insulating medium, the insulation design in the mixed state of gas and liquid needs to solve the electric field calculation problem. In this paper, based on the accurate calculation results of the electric field for different electrode models and different numbers of bubbles, the change regulations of electric field strength under typical structural conditions are summarized, which can provide a reference for insulation design.
