[0002] The installed capacity of domestic renewable energy power generation is rising rapidly. By the end of 2023, the total installed capacity of solar power generation in China will be about 610 million kilowatts, and the installed capacity of wind power generation will be about 440 million kilowatts. The total installed capacity of wind power and solar power generation has reached 1.05 billion kilowatts. It is expected that the goal of "the total installed capacity of wind power and solar power generation will reach 1.2 billion kilowatts in 2030" will be completed ahead of schedule. The rapid development of domestic renewable energy power generation has brought huge pressure on the construction of power grids. The problem of new energy consumption has become increasingly prominent. On the basis of the flexibility transformation of thermal power, a large number of supporting energy storage power stations are needed to solve the problem of new energy consumption. Energy storage is a key link in the construction of new power systems. It can be foreseen that a large number of energy storage power stations will be built, most of which are electrochemical energy storage power stations.

[0003] Regarding the specifications for setting up lightning protection devices in the energy storage equipment layout area of ​​electrochemical energy storage power stations, please refer to the "Electrochemical Energy Storage Power Station (Draft for Comments)" and "Electrochemical Energy Storage Power Station Design Specifications (GB 51048-2014)". The general practice currently adopted is to set up a number of 25-40 meter high lightning rods in the station area for lightning protection. However, this method has the following problems: (1) It affects the layout of the master plan. The lightning rod is high and has a large foundation. There are distance requirements from roads, walls and electrical equipment. When the master plan is arranged, the land use index will increase. (2) The amount of steel used increases, and the investment increases. The amount of steel used in lightning rods is large, which leads to increased investment costs. Utility Model Content
