抄録
In general, a polymer insulator applied high voltage reaches a breakdown through a development of electrical trees. Magnesium hydroxide, metal hydroxide, has the property of releasing crystallization water at a high temperature. If the energy of the partial discharge is used by the decomposition of the magnesium hydroxide, the growth of an electrical tree will be constrained and the lifetime of the polymer insulator could be expected to improve. Therefore we have studied the effects of the magnesium hydroxide on treeing. It was confirmed that the electrical breakdown lifetime of epoxy resin with 30 phr of magnesium hydroxide was 100 times longer than that of the epoxy resin without it. Magnesia was detected by the electron beam diffraction analysis of the fillers located near electrical tree, and it showed that a dehydration reaction of magnesium hydroxide was took place. In other words, as an explanation of the restraint effect of an electrical tree, the effect of the energy dispersion of partial discharge was suggested in addition to the barrier effect of the fillers.
