| 摘 要： | 为推算同塔四回线路跨越建筑物时所需的安全距离,以500 kV同塔四回线路为例,采用CDEGS软件仿真计算线路跨越、邻近不同高度建筑物时建筑物顶部和阳台处的工频电场畸变情况,并以此推算了垂直排列同塔四回线路跨越建筑物的最小安全垂直距离和最小安全水平距离。结果表明,建筑物附近的畸变电场成为制约输电线路与建筑物安全距离的关键因素;现有规程推荐的线路与建筑物的安全距离已不再适用于同塔四回线路;建筑物与线路间所需的安全距离由线路电压等级、建筑物高度、杆塔结构等因素共同决定。最后,给出110 kV、220 kV、500 kV同塔四回线路以及220 kV/110 kV5、00 kV/220 kV混压同塔四回线路跨越建筑物时所需的安全距离,其计算方法与结果可为输电线路与建筑物交叉跨越提供工程参考。

| Abstract: | To calculate the secure distance of quadruple-circuit transmission lines on the same tower with vertical arrangements passing over buildings,power-frequency electric field distortion on the roof and the balcony is calculated and analyzed with CDEGS when 500 kV quadruple-circuit transmission lines pass over buildings.And the secure distance between conductors and building is proposed based on distorted electric field,including minimum vertical secure distance and minimum horizontal secure distance.The result... |
