Enhancing The Operating Condition Analysis And Defense Ability Of Transmission Line Of Qinghai Power Grid Major: Electrical Engineering

Power is the relationship between social economic development and people’s basic life safeguard public utilities,plays an important role in the national economy,power outage will have serious economic consequences and bad social influence.Transmission line as the core support part of power grid,the distribution of surface is wide,long stretch,vulnerable to a variety of man-made or damage to the environment.At the same time,with the continuous propulsion and power grid construction the rapid development of science and technology,new equipment,new specification and application of new technology,for the operation of the power grid transmission line maintenance has brought about many new problems.This paper by qinghai power grid as the main research object,with the running situation of qinghai power grid is proposed overhead transmission line operation maintenance.Qinghai power grid in recent years the overhead transmission line tripping and operation failure condition has carried on the statistical analysis,one by one,research and analysis the cause of breakdown and tripping,including lightning,birds,ice,wind damage,external force damage,pollution flashover and geological disasters,etc.Summarizes the main characteristics and regularity of fault tripping,from two aspects of external environment and transmission line internal cause a major cause of failure is analyzed,and puts forward the effective prevention and control measures,such as the integrated application of controllable lightning rod,enhance tower external insulation configuration of the enhanced insulator,adding Qu Diao device,install ice observation device,strengthen circuit wind damage control,etc.These for overhead transmission line operation maintenance level strengthen qinghai power grid,improve qinghai power grid reliability has positive significance in promoting.
