Problems solved by technology

The working principle of the traditional lightning rod is mainly to directly connect the lightning and quickly discharge the lightning energy to the ground through the conductor of the down conductor. The strong transient current generates a strong transient electromagnetic field around the down conductor, thereby It will cause strong interference or even damage to the surrounding electronic and electrical equipment. At the same time, the strong current will be released to the ground instantly, which will cause an instantaneous rise in ground potential and generate a large step voltage, which may cause life safety accidents to nearby people or equipment.

Embodiment 1

[0040] Such as figure 1 As shown, a variable-energy current-limiting lightning rod includes a lightning rod tip 1, a lightning energy conversion device and an installation support member; wherein the lightning energy conversion device includes a lightning guiding inner core 4, an outer shell 3 and a dielectric material 5; the lightning guiding inner core 4 is set at the center of the outer casing 3, the bottom of the lightning receptor tip 1 is inserted into the inner lightning guiding core 4, and the space between the lightning guiding inner core 4 and the outer casing 3 is filled with a dielectric material 5. The top of the housing 3 is provided with an epoxy sealing layer 2 , and the middle of the epoxy sealing layer 2 is provided with a through hole for the lightning receptor tip 1 to pass through; the bottom of the housing 3 is provided with a bottom substrate 6 . The installation support component includes a support rod 7 , one end of the support rod 7 is connected with ...

Embodiment 2

[0059] Such as figure 2 As shown, in addition to the structure of Embodiment 1, the lightning rod is also provided with an insulating shielding layer 9 on the inner wall of the housing 3 . The insulating shielding layer 9 can effectively shield the huge magnetic field change caused by the discharge, and prevent the strong magnetic field from causing damage to surrounding facilities. At the same time, the insulating shielding layer 9 also effectively prevents the occurrence of electric leakage and ensures safe use.

Description

technical field [0001] The invention relates to a lightning protection and lightning protection device, in particular to a lightning rod. Background technique [0002] Lightning is a natural phenomenon in nature. When lightning occurs, super-strong current and voltage will easily cause damage to people's lives and property. Especially with the continuous improvement of people's quality of life, a large number of household appliances have entered the families of ordinary people, which has put forward higher requirements for the electricity consumption environment of the current family and industrial environments. The working principle of the traditional lightning rod is mainly to directly connect the lightning and quickly release the lightning energy to the ground through the conductor of the down conductor. The strong transient current generates a strong transient electromagnetic field around the down conductor, thereby It will cause strong interference or even damage to t...
