35kV电网单相接地的故障处理

Fault treatment of single phase grounding in 35kV Power Grid

广东电网发展日新月异,电能以超高压交直流为主动脉,220kV交流为支动脉,从各个电厂的输送至千家万户。动脉作用巨大,35kV电网也在县乡农村地区像毛细血管一样发挥着不可缺失的作用。在地调调度员的日常工作中,常常面对繁多的35kV电网故障,其中单相接地是最常见的故障。如何在快速处理故障与减少用户停电时间的平衡秤两端做好协调,需要调度员长时间的工作沉淀与科学的故障处理方法。

Guangdong power grid development with each passing day,electric energy to ultra-high voltage AC and DC as the main artery,220kV AC as the branch artery,from each power plant to thousands of households.Arteries play a huge role,and the 35kV power grid also plays an indispensable role in the county,township and rural areas like capillaries.In the daily work of dispatchers on duty,they often face a variety of 35kV power grid faults,among which single-phase grounding is the most common fault.How to make a good coordination between the two ends of the balance scale to deal with the fault quickly and reduce the user’s power outage time requires the dispatcher’s long-term work and precipitation experience and scientific fault treatment methods.
