Research On Lighting Protection Technique Of 110kV Transmission Line In Taizhou Area

Under the background of the rapid development of society and economy in China,the scale of power system has also been gradually expanding.A higher requirement for power supply reliability and safety of network has been brought.With the scale of Taizhou electric power grid expanding,Taizhou region economic development and the demand for electricity and installed capacity is increasing.Power grid is gradually improving.Taizhou power grid is to realize the power grid power,its running situation of power grid security and stability in Jiangsu and even the east China power grid has a critical influence.In recent years Taizhou area caused by lightning line tripping accidents there are more and more,has seriously affected the normal operation of power system,need analysis and corresponding improving measures are put forward.In order to solve the exceeded problem of Transmission line lightning protection measures in Taizhou electric power grid,it formulates Lightning protection measures.Firstly,this paper analyzes the present situation of Taizhou region lightning grid situation in the region,transmission line.The environment of the thunder and lightning tripping of Taizhou region is analyzed carefully,the general rules of lightning trip-out reasons in the region is summarized.Then lightning protection technology measures is analyzed,which are used in Taizhou area test,verify the application effect of these measures,including lower ground resistance,increase the lightning protection equipment and other lightning protection technology.Risk of transmission line lightning trip-out hierarchies,in Taizhou area 110 kV transmission line lightning protection emphasis respectively put forward the corresponding control measures to reduce ray pollution accidents,including improve the insulation level of line tower,using drag-reducing new technology,reduce the wire protection Angle,the use of line lightning arrester,the unbalanced insulation,etc.Through before and after the lightning protection governance data show that the lightning protection technology based on line risk hierarchy application effect is remarkable.
