experiment example

[0081] Lightning effect verification of experimental example, assembled type lightning receptor of the present invention

[0082] The advantage of the assembled lightning-termination device of the present invention is that it can neutralize lightning charges in advance to reduce the intensity of lightning discharge. In addition, lightning can be received in advance to realize the leading role of ionization. After testing, the air-termination device of the present invention can achieve the following lightning-termination effects:

[0083] Table 1

[0084]

[0085] When the average value of the atmospheric electric field is 130V.m ‐1 , the assembled lightning-termination device of the present invention can reduce the lightning discharge intensity of 10%-20%; when the average value of the atmospheric electric field is 260V.m ‐1 , the assembled air-termination device of the present invention can reduce the lightning discharge intensity by 50% to 70%; when the average value of ...

Abstract

The invention provides a lightning pin and a lightning connector thereof, a lightning rod, belonging to the technical field of electrical engineering. The lightning pin includes an aluminum core, a silver intermediate layer attached to the surface of the core, and a copper outermost layer attached to the outer surface of the intermediate layer. The lightning connector comprises a lightning connector needle and a lightning charge neutralizer; and the lightning connector comprises a lightning connector needle and a lightning charge neutralizer. The lightning charge neutralizer is a cake structure, and a plurality of filaments protrude radially from the outer edge of the cake structure to make the whole cake structure be scattered. The bottom of the column is connected with the top surface ofthe cake structure.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to a lightning-termination needle, its lightning-termination device, and a lightning rod. Background technique [0002] The lightning receptor is the lightning arrester in the lightning protection grounding system. The lightning receptor is a metal object specially used to receive direct lightning strikes (thunder flashes). The metal rod of the lightning receptor is called a lightning rod. The metal wire of the lightning terminal is called a lightning conductor or an overhead ground wire. The metal belt and metal mesh of the lightning receptor are called lightning protection belts. All lightning terminals must be connected to the grounding device through the grounding down conductor. [0003] The upper end of the lightning rod / termination device is generally equipped with a needle for the main function of lightning connection. Common needles are mostl...
