The mechanism of chopped wave overvoltage of transformers caused by insulator arc-over chopped wave after lighting stroke terminal tower is analysis emphasize.
针对截波产生的原因，重点分析了雷击变电站终端杆塔使绝缘子闪络产生截波，并引起变压器截波过电压的机理。
For large space, air terminal building adopts air supply tower, floor exhaust grillage and smoke exhausting skylight controlled by infrared detector.
该工程结合大空间场所的特点，采用了地面送风亭射流送风方式、地面排风方式及红外线对射探测器控制的排烟天窗。
The method for fault location of the parallel transmission lines on the same tower based on single-terminal current is proposed in this paper.
提出了一种基于同杆双回线单端电流量的故障测距方法。在故障状态下，双回线可以分解成同向网和环流网，其中环流网只与双回线有关，且两端电压为零。
