浅谈消弧线圈在电网中的应用

随着城市电网改造步伐的加快,原低压架空供电线路全部改为电缆入地供电,为长治创建全国文明城市、旅游城市作出了应有的贡献,当在美化城市的同时,供电电缆的增加,电网电容电流成倍增加,导致电网发生单相接地时发生间隙性接地,产生过电压,损坏设备,经过电力调度控制中心相关专业人员的计算论证,合理使用消弧线圈很好的解决了该问题。

On the Application of Arc Suppression Coil in the Power Grid

With the accelerated pace of urban power grids reform,the original low voltage overhead power lines all changed the underground cable power supply to make due contribution to creating national civilized city and tourist city for Changzhi.When embellishing city,the electric cables are increasing,capacitive current is fold increasing,which causes power grid generates intermittent grounding when single-phase ground ocurred,generating over-voltage,resulting in the damage to equipment,through the calculated demonstration of professionals of the power dispatch control center,rational use of arc suppression coil can solve the problem.
