摘要
随着经济的迅速发展和城市电网的不断升级,城区高压电缆数量持续增大,高压电缆的安全运行直接影响了城区的供电可靠性。提出了一种改进的二次脉冲法定位电缆主绝缘故障,并通过案例验证了此方法的可行性。
With the rapid development of economy and the continuous upgrading of urban power grid, the number of high voltage cables keeps growing. Meanwhile, the safe operation of high voltage cables affects the power supply reliability of urban areas directly. A new positioning of cable main insulation failure based on improved secondary pulse method is proposed, which is demonstrated the feasibility of the method by case study.
