Embodiment 1
[0025] A lightning arrester is composed of a lightning rod 1, a lightning arrester and an iron core 3.
[0026] The top of the iron core 3 is provided with a first insulating block 2, and the bottom is provided with a second insulating block 5; On the top of the lightning protector; the iron core 3 is wound with a coil 4, the upper end of the coil 4 is connected to the lightning pin 1, and the lower end is connected to the inner core 9 of the lightning protector.
[0027] The lightning protector includes a conductive shell 7 with a hollow closed cavity inside, and a conductive inner core 9 is set in the cavity, the top of which is connected to the lower end of the coil through the cavity, and the bottom is placed at the bottom of the cavity through an insulating plate. The circumference of the inner core is filled with non-linear resistance particles 8, including ZnO non-linear resistance particles 8; the ground lead 10 is connected to the shell.
[0028] ZnO non-linear resis...
Embodiment 2
[0032] Based on the structure of Embodiment 1, a strut 6 is arranged between the lightning protector and the iron core 3 .
[0033] The pole 6 is an insulating hollow pole, and the iron core 3 is arranged on the top of the inner core 9 of the lightning arrester through the pole 6 , and the iron core 3 and the pole 6 are separated by the second insulating block 5 at the bottom of the iron core 3 . The lower end of the coil 4 is connected to the inner core 9 of the lightning arrester from the inner cavity of the rod.
Embodiment 3
[0035] Based on the structure of Embodiment 2, the two sides of the lightning arrester are respectively provided with an incoming lead wire 11 and an outgoing lead wire 12 penetrating through the cavity;
[0036] Such as figure 2 Shown is a schematic diagram of a linear series connection structure, the lightning receptor 1 or through the support rod 6 is set on the top of the inner core 9 of the lightning arrester at one end, and the grounding lead 10 is connected to the shell 7 of the lightning arrester at the other end.
[0037] Such as figure 2 As shown, the shell 7 of the lightning arrester at the end of the serial connection is connected to the ground lead 10 .
[0038] Such as image 3 Shown is a schematic structural diagram of area protection (including linear series connection and closed-loop series connection). The top of any lightning arrester is provided with a lightning terminal 1, and the grounding lead 10 is connected to the shell 7 of any lightning arrester....
