Reason for Burning out of Jinxiang Distribution Transformer in Shandong and its Prevention

Distribution transformer is the one of important equipment in power supply system,which undertakes the task of voltage transformation and distribution of electrical energy,and its damage will directly affect the normal production and life of user.It is the important means to discover the insulation defect of distribution transformer early and to stop burn accident of distribution transformer. The paper analyzed the reason for burning out of distribution transformer and insulation deterioration,and presented the precautionary measures.At the same time,a kind of operation wave fault detection instrument was introduced,which can discover the insulation defect in distribution transformer early.
