Influence of temperature and moisture joint action on oil-paper insulation compound electric field distribution
In the paper,the electric field change in transformer oil and oil-impregnated insulation paperboard within wide temperature range(20℃~100℃)was studied.The influence law of temperature on oil-paper insulation electric fields was summarized.Oil-paper insulation electric field distribution under the action of different wave-form voltages was simulated for analysis.The electric field distribution condition during moisture balance steady state and transient state was obtained.The reasons of electric field distribution change were analyzed.
