열화된 식물성 절연유의 벤조트리아졸과 온도의 유동대전 영향

초록

In this paper, the experiments about streaming electrification of mineral and vegetable oils in transformers was performed. The effects that temperature, quantity of Benzotriazole (anti-electrification agent), degree of aging affect streaming electrificaton were investigated. The type of series electrification system was selected to make its analysis easy. Mineral oils represented a maximum value at 40℃ and Vegetable oils did at 60℃. Variations of the streaming electrification by quantity of Benzotriazole were similar regardless of a sort of oils. The effects of aging time of oils were small.
