Research On Operation And Maintenance Management Of Low Voltage Power Distribution Line In Qingyuan Area

For power grid enterprises,the safe and reliable supply of power system is the lifeline of stable and healthy development of enterprises.As the main component of distribution network,medium and low voltage distribution line is the most common form of electric power transmission.In addition,the distribution line directly to the user terminal,is the last stop of power transmission,the user power supply situation is different,if maintenance is not in place,will have a higher rate of equipment failure,affect the customer satisfaction of electricity services,also indirectly affect the safe operation of power grid.Because of the great influence of the geographical environment,weather change and economic development,the middle and low voltage distribution lines have great difficulties in the routine maintenance and overhaul of medium and low voltage distribution lines.Qingyuan region dominated by mountains and hills,is a "minefield" throughout the year,more rain,luxuriant trees,lightning,tree barrier is the biggest threat to the safe operation of power supply line;at the same time,Qingyuan City,superior location,convenient transportation,is located in the Pearl River Delta "one hour life circle in recent years.The rapid economic development,real estate construction,construction frequent,often caused by the power supply line wire rod phenomenon because of the construction vehicles;in addition,due to the economic development of Qingyuan city started low level is not high,power supply enterprise investment can?t keep up,the rural power grid line equipment old,there are many low voltage area,user complaints and so on,to the Qingyuan area in the low line maintenance management has brought great difficulties.This paper mainly based on low voltage line and the running status of equipment in Qingyuan region in recent years is the low voltage line equipment common line equipment breakdown and hidden trouble for furtherstudy,combination of Qingyuan region geography,weather,and the characteristics of social and economic development,with solving problems,the health level of ascension in the low-voltage distribution line as the goal,mainly in the lightning protection,repair,prevent the external force damage,prevent users go out fault,improve employees' skills level,etc.,put forward a feasible management measures and technical measures,improve operation maintenance and management level in low voltage power distribution circuit,effectively decrease The Times of low pressure in grass-roots repair and reduce customer average power outage time,guarantee the stability of safe and reliable power supply,improve the image of foreign enterprises and promote the local economic and social development.
