Under normal voltage, it exhibits high resistance. Under overvoltage conditions, the resistance drops sharply. Zinc oxide lightning arresters are widely used in lightning protection and overvoltage protection of 0.25-550kV electrical systems and electrical equipment due to their advantages such as no discharge delay, no power frequency follow-on, low residual voltage, large flow rate, small size, light weight, and simple operation and maintenance.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Embodiment 1:

[0044] like Figure 1 - Fig.14 As shown, an embodiment of the present invention provides a lightning arrester for a high-altitude power distribution system, including a lightning arrester body 1, a bottom cylinder 8, a connecting cylinder 4, an elastic member 13 and a connecting rod 15. The purpose of its design is to facilitate construction personnel in the high-altitude operation process to quickly and efficiently complete the installation of the lightning arrester for the high-altitude power distribution system, improve installation efficiency, reduce safety risks, and ensure the verticality of the lightning arrester for the high-altitude power distribution system after installation, so that after the lightning arrester for the high-altitude power distribution system is installed, it can vertically support the metal wire 3.

The diameter of the matching circular hole 12 is larger than the length of the longest straight line connecting two points on the end face contour of the cam hole 9. The intuitive effect of alignment on the surface is that the cam hole 9 can be completely located inside the matching circular hole 12, the elastic member 13 is arranged on the inner top of the bottom cylinder 8, the connecting rod 15 has a cam segment 1503, the connecting cylinder 4 is sleeved on the outside of the bottom cylinder 8, the connecting rod 15 passes through the cam hole 9 and the matching circular hole 12, and the cam segment 1503 of the connecting rod 15 is located inside the matching circular hole 12, and the protruding position of the cam segment 1503 faces downward.
