All-insulation overhead line
The invention discloses an all-insulation overhead line which comprises a plurality of telegraph poles and overhead lines erected among the telegraph poles, pole transformers are arranged between the telegraph poles and the overhead lines, and the pole transformers are connected into the overhead lines through pole transformer high-voltage downleads, drop-out fuses, fuse cross arms and connecting wire clamps. A pole transformer low-voltage pile head on the low-voltage side of the pole transformer is led to each user through a cable; the rod transformer high-voltage downlead is connected with the high-voltage side of the rod transformer through a quick connector; the drop-out fuse is a closed type all-insulation fuse; the fuse cross arm adopts an insulating cross arm; a wire clamp insulating cover is arranged outside the connecting wire clamp in a covering manner; and a pile head insulating cover is arranged outside the pole transformer low-pressure pile head in a covering manner. According to the 10kV overhead all-insulation line, all-insulation transformation is carried out on a 10kV overhead line in the prior art, the defect of the line on the inductive lightning overvoltage prevention capability can be overcome, and the lightning trip-out rate is reduced.
本发明公开了一种全绝缘架空线路，包括若干电线杆以及架设在各电线杆之间的架空线，所述电线杆与架空线之间设置有杆变，所述杆变通过杆变高压引下线、跌落式熔断器、熔断器横担和接续线夹接入所述架空线，所述杆变的低压侧的杆变低压桩头通过电缆引至各用户；所述杆变高压引下线与所述杆变的高压侧之间通过快插接头连接；所述跌落式熔断器采用封闭型全绝缘熔断器；所述熔断器横担采用绝缘横担；所述接续线夹外部罩设有线夹绝缘罩；所述杆变低压桩头的外部罩设有桩头绝缘罩。本发明的10kV架空全绝缘线路，对现有技术中的10kV架空线路进行全绝缘化改造，可以弥补线路对感应雷过电压防范能力的不足，降低雷击跳闸率。
