Lightning protection structure of 10kV distribution transformer additionally provided with parallel gap

The invention discloses a lightning protection structure of a 10kV distribution transformer additionally provided with a parallel gap. The method comprises the steps that in the first three base towers of the 10kV distribution transformer, only one phase of one circuit of the same base tower is provided with a parallel gap, the two parallel gaps of two base towers adjacent left and right are installed in the other two phases of the three phases respectively, and the first three base adjacent towers are provided with a group of three parallel gaps in a matched mode. According to the invention,the lightning overvoltage protection effect invading the distribution transformer can be achieved. 本发明公开了一种加装并联间隙的10kV配电变压器的防雷保护结构，包括：10kV配电变压器的前三基杆塔中，同一基杆塔的一回线路仅在一相安装并联间隙，左右相邻的二基杆塔的两个并联间隙分别安装在三相中的另外两相，前三基相邻杆塔配合安装一组三个并联间隙。本发明可达到入侵到配电变压器的雷电过电压防护效果。
