Lightning rod and its pole

Abstract

The invention provides a lightning rod, and belongs to the technical field of lightning protection engineering. The lightning rod comprises one or multiple lightning receiving posts. At least one lightning receiving post uses hafnium or a hafnium alloy as raw material. The invention also provides the lightning receiving post used for the lightning rod. The lightning receiving post uses hafnium or the hafnium alloy as the raw material. The invention also provides an application of the lightning rod and / or the lightning receiving post in the aspect of lightning protection and / or lightning prevention or the aspect of lightning protection and / or lightning prevention in the super-altitude environment. With application of the lightning rod and / or the lightning receiving post, transient heat bearing capacity of the lightning rod can be effectively enhanced to be more than 4100 DEG C, and resistivity of the lightning rod can be maintained at (20 DEG C) the level within 2.6548-5.196x10<-8>ohm / M simultaneously so that melting and damage caused by high temperature in lightning protection in the super-altitude environment can be effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of lightning protection engineering, and in particular relates to a hafnium-based lightning rod and a lightning pole. Background technique [0002] Lightning rods, also known as lightning rods, lightning rods, lightning arresters, and lightning rods, are devices used to protect buildings (structures), tall trees, etc. from lightning strikes. When a thundercloud discharge approaches the ground, it distorts the ground electric field. At the top of the lightning rod, a space where the local electric field is concentrated is formed to influence the development direction of the lightning pilot discharge, guide the lightning to discharge to the lightning rod, and then introduce the lightning current into the earth through the grounding down conductor and the grounding device, so that the protected object is not struck by lightning. . [0003] In the prior art, based on the basic lightning protection function of ...

Problems solved by technology

[0009] However, there are still the following blanks in this field: In the ultra-high altitude environment of more than 200 meters, the high temperature generated by strong convective lightning can often reach about 3000 degrees. The temperature is below 1600, so there are often accidents where the ordinary lightning rod is damaged by the thermal and mechanical effects of the lightning current and partially melted instantly. At the same time, the strong induced charge generated by the lightning connection will cause the lightning rod to become a lightning device

Therefore urgently need to develop a kind of novel lightning rod that can be used in super high-altitude environment, have good high temperature resistance, and this area has not seen relevant such report yet
