摘要
文中分析了交联聚乙烯电缆交流耐压试验采用变频串联/串-并联谐振试验方法的优缺点,并以一回220kV长距离电缆进行变频谐振耐压试验为例,详细介绍了试验前有关参数计算、试验装置、试验过程及注意事项等,对现场不同试验方案进行了比较。试验结果表明,采用变频串-并联谐振试验方法对长距离交联聚乙烯电缆进行耐压试验更符合现场要求。
The advantages and disadvantages of several AC withstand voltage tests using frequency series/ series-parallel resonant test for the cross-linked polythene cable are analyzed. Taking 220kV long cable frequency resonant withstand voltage test for example, the paper introduces the parameter calculation, equipment, process and announcements etc in detail, and also compares the different test schemes. Experiment results show using frequency series-parallel resonant test method of long cross-linked polythene cable withstand voltage test is be up to the mustard.
