谈城市110kV以下配电线路改造杆塔的选型和使用

城市老城区随着旧房改造和用电设备的增加,用电量不断增加,而原来供电线路的供电能力有限,因此经常出现线路过载造成开关跳闸和导线过热造成断线等故障.近年来,一些城市对老城区的旧线路和供电方式进行更新改造,但由于历史原因和客观条件的限制,无法采用电缆直埋的方式进行改造,需用架空明线的方式进行供电改造.

A Discussion of the Selection of Tower When Improving Urban 110kV Distribution Line and Its Use

With the improvement of old buildings in urban old district and the increase in electrical equipment,quantity of electricity is increasingly needed.The capacity of the old power supply lines is limited.Thus,switch tripping caused by line overload and electrical disconnection caused by overheated conductor.In recent years,some cities have been improving the old power supply lines and the ways of power supply in the old district.However,owing to historical cause and objective condition, some cities cannot improve them by means of directly hiding cable but aerial line.
