Distribution arrester failure has accounted for a considerable proportion of the total number of faults in the distribution network, and has become one of the main factors affecting the reliability of power supply in the distribution network. Therefore, from the test point of view of lightning arrester lightning impact withstand capacity is essential. In this paper, for the 10 kV multi-gap arrester specimen, to carry out positive and negative polarity of the lightning impact voltage test, through the recorded discharge process high-speed image, can be obtained multi-gap arrester impact discharge process also includes the process including the initial stage, movement and development stage, dissipation and recession stage, the whole process duration of 0.6 ms. through the “lift method” to determine the specimen's 1.6 ms. Through the “lifting method” to determine the specimen of 1.2/50 μs positive and negative lightning impact 50% discharge voltage were 90.5 and 100.3 kV, and then based on the atmospheric environment at the time of the test on the experimental results of the correction, the positive and negative lightning impact 50% discharge voltage correction value of 89.8 and 99.5 kV, to meet the provisions of the standard.

摘要

Distribution arrester failure has accounted for a considerable proportion of the total number of faults in the distribution network, and has become one of the main factors affecting the reliability of power supply in the distribution network. Therefore, from the test point of view of lightning arrester lightning impact withstand capacity is essential. In this paper, for the 10 kV multi-gap arrester specimen, to carry out positive and negative polarity of the lightning impact voltage test, through the recorded discharge process high-speed image, can be obtained multi-gap arrester impact discharge process also includes the process including the initial stage, movement and development stage, dissipation and recession stage, the whole process duration of 0.6 ms. through the “lift method” to determine the specimen's 1.6 ms. Through the “lifting method” to determine the specimen of 1.2/50 μs positive and negative lightning impact 50% discharge voltage were 90.5 and 100.3 kV, and then based on the atmospheric environment at the time of the test on the experimental results of the correction, the positive and negative lightning impact 50% discharge voltage correction value of 89.8 and 99.5 kV, to meet the provisions of the standard.
