説明
This report deals with the mechanism of space charge accumulation in cross-linked polyethylene (XLPE) under DC electric field. Space charge was measured by the pulsed-electroacoustic method with applying DC stress of 20kV/mm. A large amount of hetero space charge accumulated in fresh XLPE sample. Factors to influence the space charge accumulation were analyzed in regard to cross-linking by-product and antioxidant. No space charge was seen when the fresh sample was degassed to remove cross-linking by-products. Introducing acetophenone, one of the cross-linking by-products, in the degassed sample brings no space charge, suggesting that acetophenone itself could not be the direct factor of space charge formation. However, heating this sample up to 150°C brings hetero space charge as were seen in the fresh sample. It is concluded that the hetero space charge may be formed when impurities such as antioxidant dissociate thermally with the help of acetophenone and that the dissociate species are attracted towards both electrodes under DC field to form the hetero space charge.
