县城电网改造中若干问题的探讨

为解决县城电网改造中存在的诸如线径选择、负荷分区、电杆选型、环网化和绝缘化等技术问题,根据地区县城电网的特点,结合城网规划导则和在县城电网改造实际工作中摸索的经验,提出了以城区道路为界重新规划供电区域、根据远期负荷确定导线线径、采用手拉手环网供电等一套切实可行的解决办法,同时提出,改造应遵循总体规划,分步实施,坚持可持续发展及与提升城市的格调与品位的原则。对同类型地区县城电网改造具有一定的借鉴意义。

A Study of Problems in the Reform of County City Power Grid

To solve the technical problems such as choice of line diameter,load distribution,choice of pole type,circulating of power grid and insulation,the paper,based on the character of local power grid and in combination with the guide code for city power grid scheme and the experiences obtained in practical grid reform.Presents some practical resolutions——replanning power supply district according to city roads,deciding line diameter according to long term loads,supplying power through hand by hand circulating grids,and so on.It also suggests that the principle be followed to plan comprehensively,to execute step by step,to insist on continuous development and to boost city's style and quality,and has certain reference to the same sort of county city's power grid reform.
