​Where is lightning protection detection used?

    Everyone knows about lightning protection detection, and the damage caused by lightning to various buildings and equipment is obvious. What are the applications of lightning protection detection?  

   1) Electric power industry

   In the past three years, the power system has invested approximately billions of yuan in lightning protection systems and power grounding in Beijing every year, mainly focusing on four aspects: lightning protection of secondary power systems, grounding of substations, grounding of power plants, and grounding of transmission line towers. . It is estimated that the State Grid Corporation's annual investment in secondary lightning protection for substations will be around hundreds of millions of yuan, and its annual investment in power system grounding will be around billions of yuan, of which the demand for grounding materials will be around 100 million yuan.

   2) Railway industry

   Many of the top 100 enterprises are railway bureaus. At present, the comprehensive lightning protection and grounding system transformation projects of electrified railway traction networks have been launched in dozens of railway bureaus across the country. The main projects involved are station information lightning protection transformation projects and system protection. Lightning and grounding, rail grounding, protective line (return line) grounding, equipotential bonding, etc. The annual market space for lightning protection and grounding is about one billion, and the market space for surge protector products alone is about hundreds of millions. At present, there are many Beijing lightning protection brands and companies that have obtained certification, including foreign brands, domestic brands and railway system brands.

   3)Petrochemical industry

In the past two years, there has been a significant increase in lightning protection and grounding projects for petrochemical systems. In recent years, the market has grown by more than 45%, which is rare in any industry. The market space for lightning protection in Beijing is about billions, mainly concentrated in refinery control system lightning protection and refinery grounding, storage tank area lightning warning and direct lightning protection and grounding, self-use power distribution system lightning protection and grounding, metal pipelines And bridge grounding, etc.; in the traditional sense, small projects such as oil tank grounding and gas station lightning protection grounding no longer account for a large proportion. However, the current lightning protection products used in the petrochemical industry are mainly surge protectors. The annual market demand for such lightning protection products is large, and the growth rate is very alarming.
