摘要
带电作业是保障电网安全稳定运行的一项重要技术工作。通过分析得出,耐张塔绝缘子上强电场分布不均是导致带电更换耐张塔导线侧自爆绝缘子作业时间较长的主要原因。为此,研制了一套能实现强电场电位转移的装置,并通过试验检测和实际带电作业试用证明了该装置实用、有效。
Live working is an essential technical task to ensure the safe and stable operation of power grids.The analysis shows that the uneven distribution of strong electric field on the tension tower insulators is the major factor causing the long-last live replacement of tension resistant insulators.Therefore,a device which enables the potential transfer for strong electric field is developed,and it is proved to be practical and effective based on test detection and actual trials in live operation.
