摘要
本文根据变电所内阀型避雷器的直击雷保护作用,分析和验算了变电所高低压两侧出口线路分别小于6回、接地电阻小于2Ω以及避雷器与被保护的电气设备间的距离不超过15～20m时,就能允许避雷针装在配电装置的构架上,经济效果较显著。
According to the protective action of valve arrestor for direct lightning stroke in substation, this paper analyzes, calculates and proves that, when the number of substation outlet lines of high voltage and low voltage are less than 6 respectively, the ground resistance is less than 3 Ω and the distance between the arrestor and the electrical eguipments to be protected is less than l5～20m, the lightning rods may be installed on the structure of the switch yard, the economic effect is prominent.
