摘要：The improper control of the production process can easily cause defects in the power equipment that cannot be found by routine tests. In this paper, X-ray detection technology was used to test high voltage porcelain bushings, high voltage composite bushings and metal oxide surge arresters polymeric with series gaps, which are prior to working. It is found that there are air gaps between the waterproof glue on the flange and the body of bushings, which will increase the vibration frequency of the porcelain bushings and will cause the bushings to be abnormally stressed. There is a misalignment or poor contact between the contact surface of internal valve pieces of the MOA, which will reduce the flow capacity of the series valve pieces. The above phenomena will reduce the reliability of the power grid operation. This paper believe that the current routine tests should be improved, X-ray detection technology should be used as a new routine test for high-voltage bushings and arresters to improve the reliability of equipment operation.
