【摘要】：對于電網企業(yè)而言,電力系統(tǒng)的安全可靠供應是企業(yè)穩(wěn)定健康發(fā)展的生命線。中低壓配電線路作為配電網主要組成部分,是當前最為常見的電力輸送形式,其最大的特點線長、點多、面廣。另外,配電線路直接面對用戶端,是電力輸送的最后一站,用戶端的供用電的情況各有差異,如果維護管理不到位,將會產生較高的設備故障率,影響客戶用電服務滿意度,同時間接影響著電網的安全運行。由于中低壓配電線路受當地地理環(huán)境、天氣變化、經濟發(fā)展等影響較大,中低壓配電線路的常規(guī)維護與檢修存在較大的困難。清遠地區(qū)以山地、丘陵為主,是出了名的“雷區(qū)”,一年四季雨水較多,樹木生長茂盛,雷擊、樹障是供電線路安全運行的最大威脅;同時,清遠市區(qū)位優(yōu)越,交通便利,位于珠三角“一小時生活圈”內,近年來經濟發(fā)展快速,樓盤建設多,施工頻繁,經常發(fā)生因施工車輛造成供電線路斷線斷桿現(xiàn)象;另外,因清遠經濟發(fā)展起步低,城市化程度不高,供電企業(yè)電網投資跟不上,農村電網線路設備殘舊,存在較多的低電壓臺區(qū),用戶意見投訴多等等,這給清遠地區(qū)的中低壓線路維護管理帶來了很大的困難。本文主要根據清遠地區(qū)中低壓線路和設備運行狀況,對近幾年中低壓線路設備常見的線路設備故障和隱患進行深入研究,結合清遠地區(qū)的地域、天氣、社會經濟發(fā)展等特點,以破解難題,提升中低壓配電線路健康水平為目標,主要在防雷、清障、防外力破壞、防用戶故障出門、提升員工技術技能水平等方面,提出具有可行的管理措施和技術措施,全面提升中低壓配電線路運行維護管理水平,有效減少基層供電企業(yè)中低壓線路搶修次數,減少客戶平均停電時間,保證電力安全可靠穩(wěn)定供應,提高企業(yè)對外形象,促進當地經濟社會發(fā)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.
