山东省苍山县1968年上电,由于受资金材料的限制,先后共架设低标准配电线路1200km.其中有500km服役期超过20年.因此,配电事故居高不下,影响了全县的工农业生产和居民生活用电.同时,也影响了供电局本身的经济效益.针对这一情况,自1993年以来,苍山县供电局在努力提高送电线路健康水平的同时十分重视配电线路的改造.局领导深入实际调查研究,采取治本又治标的措施,共投资500万元以上,改造10kV配电线路415km;更换绝缘材料17750只;处理各类缺陷810个.线路完好率达到95%,其中一类的占80%以上.线路的整体状况有了很大的提高.配电事故率较1993年下降了75%,提高了供电可靠性.收到了很明显的效果,得到了各级政府的赞扬.主要从以下几方面着手:
Cangshan County of Shandong Province was powered up in 1968. Due to restrictions on funding materials, it had set up low-standard distribution lines of 1200 km. There were 500 km of service for more than 20 years. As a result, distribution accidents remained high, affecting the entire county’s workforce. Agricultural production and electricity consumption for residents have also affected the economic benefits of the power supply bureau. In view of this situation, since 1993, the Cangshan County Power Supply Bureau has paid great attention to the distribution lines while striving to improve the health level of power transmission lines. Restructuring. Bureau leaders conducted in-depth investigations and research and adopted measures to address the root cause and the symptoms. A total of 5 million yuan was invested in the transformation of 415km of 10kV distribution lines, 17750 replacements of insulation materials, and 810 defects of various types. The line in good condition reached 95%. One group accounted for more than 80%. The overall condition of the line has been greatly improved. The rate of power distribution accidents has dropped by 75% compared with 1993, which has improved the reliability of power supply. It has received very obvious results and has received governments at all levels. The praise mainly starts from the following aspects:
