Insulator and lightning arrester integrated device for current collection circuit of high-altitude wind power plant

The utility model relates to the technical field of lightning arresters, in particular to an insulator and lightning arrester integrated device for a current collection circuit of a high-altitude wind power plant, which comprises an insulating pillar core rod, and connecting pieces are arranged at two ends of the insulating pillar core rod. A first voltage limiting unit, a second voltage limiting unit and a third voltage limiting unit are sequentially arranged in the middle of the insulating pillar core rod from top to bottom, a first composite insulator string and a second composite insulator string are arranged in the middle of the insulating pillar core rod, and the first composite insulator string is located between the first voltage limiting unit and the second voltage limiting unit. The second composite insulator string is located between the second voltage limiting unit and the third voltage limiting unit. According to the utility model, the purpose of rapid arc extinguishing can be achieved without a
