Research On The Lightning Performance Of10kV Distribution Lines In Xinhui

As a result of10kV and distribution line below without overhead ground wire, lowvoltage, distance between lines is smaller, the distribution network low insulation level. In thedistribution line running total number of trips, caused by a lightning strike tripping times oflarge proportion. Distribution equipments and user equipments are damaged by lightningaccidents, lightning accidents cause large area blackout, even personal injury at seroussituation, bring losses to industrial and agricultural production, bring inconvenience topeople’s life. So the current state of lightning protection should be study and find measures toimprove zhe level of lightning protection, lightning trip out rate and damage rate ofdistribution equipments should be reduced, suring unblocked of business electrical，safety ofuser，safe and reliable operation of distribution network.Based on the10kV distribution line with bare wire in Xinhui mainly practical operationconditions, analysis of the lightning hazard. And commonly used in the lightning arrester,lightning protection line, reducing grounding resistance effect to carry on the researchanalysis, put forward it’s corresponding applicable occasions. Finally to10kV water line as anexample, to improve the lightning protection measures for demonstration and implementationeffect of alignment，put forward for the existing operating conditions of the10kV distributionline in Xinhui lightning protection measures for improving10kV line insulation levels andinstalling line arrester.
