Design And Construction Of Lightning Protection Facilities For Distribution Network In Shouguang City

10 kV distribution line is an important part of power system,because of 10 kV distribution line insulation level and operational management existence insufficiency,and with the rapid development of shouguang region distribution network and strong convective weather,affected by the direct lightning,lightning and so on caused by lightning strike,single phase grounding,with variable fault happens,the fault of has become one of the main factors affecting the safe operation of the distribution line,need to combine network reconstruction design and construction of distribution line lightning protection facilities for differentiation,by strengthening technical innovation,further reducing lightning accident,to ensure the safe operation of the distribution network.This paper introduces the principle of the basic theory of lightning and thunder and lightning disasters,shouguang in plains,mountains,tall buildings covered lightning activities such as more frequent,caused great influence to power grid,power distribution lines and substations ray harm accident happen.Seriously affected the local power supply reliability,caused huge losses to the local economy,and threatens the stability of the power grid in operation,in this paper,the distribution network lightning protection technology are discussed,the lightning tripping and lightning trip-out management ideas are analyzed.Combined with the present situation of shouguang region distribution network statistics and classification,the measures of lightning protection for power distribution lines,distribution transformer,switch on the pillars,and other complete sets of equipment distribution network lightning protection measures for application analysis,through local insulation distribution network management,clear line local insulation equipment and ancillary equipment insulation on the five types of insulation management focus.According to different regions,different lightning disturbance degree,make different measures of lightning protection technology with the integrated application of overvoltage protector,lightning protection insulator,lightning protection,lightning protection technology measures such as ground modification,improve the level of lightning protection.The implementation of the distribution network lightning protection construction of differentiation,carried out in shouguang lightning protection special governance to improve operational management level,strengthen the lightning protection device configuration level,strengthening the management of operational ability pays special attention to the equipment into the net and ensure reasonable lightning protection device selection,installed,ops,zero defect of commissioning in time,further improve the level of distribution network lightning protection ability and the safe operation of the line,distribution circuit obstacle rate decline further.
