220kV阳江站防雷保护图的绘制

Drawing 220kV Lightning Protection Grid for Yangjiang Substation

220kV阳江站经过三期技改工程,避雷针增加至19根,部分避雷针位置改变,电站内防雷保护图没有更新,需要重新绘制防雷保护图。在现场考察、测量和自编程序计算的基础上重新绘制阳江站的防雷保护图,完善了变电站的图纸和资料;发现主控楼不能防护直击雷,提出在其楼顶装设避雷带的建议,为更好的进行变电站运行管理提供可靠保证。

There are 19 lightning rods while some rods' locations have been changed after three technical improvements of 220kV Yangjiang Substation.However,the lightning protection grid has not been updated.Therefore,it is necessary to redraw the layout of the lightning protection grid.Then the blueprints and data have been enriched based on spot observation,measurement and self-developed programming.The grid indicates that the control center can not be protected.Thus,the suggestion to install lightning belts on the ...
