Abstract

The Tree phenomenon of the PMMA resin depends on an annex of the inorganic fillers and water. If the internal of an arganic insulating materials exist the fault of inorganic fillers, Void and Projecting part, the high voltage concentrates in this place. It leaves a trace about the partical breakdown and this phenomenon develops into the degration of insulating material. This paper researchses that have an effect on the tree phenomenon by the inorganic fillers and water. The results is as follow. (1) The growth of tree are less the influence of inorganic fillers. Because , the constant of water are more. (2) If the tree branches contact the inorganic filler, the advance are relaxation.

高分子材料에서 水分의 영향으로 發生되는 Tree를 硏究할 目的으로 熱的, 化學的으로 安定된 Al2,O2 및 SiO2 徵紛을 添加하여 材에 미치는 영향을 考察하였다.
