【摘要】：对于电网企业而言,电力系统的安全可靠供应是企业稳定健康发展的生命线。中低压配电线路作为配电网主要组成部分,是当前最为常见的电力输送形式,其最大的特点线长、点多、面广。另外,配电线路直接面对用户端,是电力输送的最后一站,用户端的供用电的情况各有差异,如果维护管理不到位,将会产生较高的设备故障率,影响客户用电服务满意度,同时间接影响着电网的安全运行。由于中低压配电线路受当地地理环境、天气变化、经济发展等影响较大,中低压配电线路的常规维护与检修存在较大的困难。清远地区以山地、丘陵为主,是出了名的“雷区”,一年四季雨水较多,树木生长茂盛,雷击、树障是供电线路安全运行的最大威胁;同时,清远市区位优越,交通便利,位于珠三角“一小时生活圈”内,近年来经济发展快速,楼盘建设多,施工频繁,经常发生因施工车辆造成供电线路断线断杆现象;另外,因清远经济发展起步低,城市化程度不高,供电企业电网投资跟不上,农村电网线路设备残旧,存在较多的低电压台区,用户意见投诉多等等,这给清远地区的中低压线路维护管理带来了很大的困难。本文主要根据清远地区中低压线路和设备运行状况,对近几年中低压线路设备常见的线路设备故障和隐患进行深入研究,结合清远地区的地域、天气、社会经济发展等特点,以破解难题,提升中低压配电线路健康水平为目标,主要在防雷、清障、防外力破坏、防用户故障出门、提升员工技术技能水平等方面,提出具有可行的管理措施和技术措施,全面提升中低压配电线路运行维护管理水平,有效减少基层供电企业中低压线路抢修次数,减少客户平均停电时间,保证电力安全可靠稳定供应,提高企业对外形象,促进当地经济社会发展。
[Abstract]: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 part of distribution network, medium and low voltage distribution line is the most common power transmission form at present, its biggest characteristic line is long, many points, wide range. In addition, distribution lines are directly facing the user side, which is the last station for power transmission. There are differences in the situation of power supply and consumption at the user side. If the maintenance and management are not in place, there will be a higher failure rate of the equipment, which will affect the customer's satisfaction with electricity service. At the same time, it indirectly affects the safe operation of power grid. Due to the influence of local geographical environment, weather change, economic development and so on, the routine maintenance and maintenance of medium and low voltage distribution lines are difficult. The Qingyuan area is dominated by mountains and hills, and is a famous "minefield". Rain Water has more trees, lightning strikes, and tree barriers are the biggest threats to the safe operation of power supply lines. At the same time, Qingyuan City has a superior location and convenient transportation. Located in the "one-hour life circle" of the Pearl River Delta, in recent years, the economy has developed rapidly, buildings have been built more frequently, and the power supply lines have been cut off frequently because of construction vehicles. In addition, Qingyuan's economic development has started at a low level. The level of urbanization is not high, the investment of power supply enterprise can not keep up with, the equipment of rural power network is dilapidated, there are more low voltage stations, many users' opinions and complaints, etc., which brings great difficulties to the maintenance and management of medium and low voltage lines in Qingyuan area. According to the operation status of medium and low voltage lines and equipment in Qingyuan area, this paper makes an in-depth study on the common line equipment failures and hidden dangers of medium and low voltage line equipment in recent years, combining with the characteristics of Qingyuan area, such as region, weather, social and economic development, etc. Aiming at solving difficult problems and improving the health level of medium and low voltage distribution lines, the paper puts forward some feasible management measures and technical measures in such aspects as lightning protection, obstacle clearing, protection against external force damage, preventing customers from going out of trouble, improving the technical skills of employees, and so on. Comprehensively improve the management level of operation and maintenance of medium and low voltage distribution lines, effectively reduce the number of rush repairs of middle and low voltage lines in grass-roots power supply enterprises, reduce the average outage time of customers, ensure the safe, reliable and stable supply of electric power, and improve the external image of the enterprises, Promoting local economic and social development.
