Description

Technical Field

[0001] The utility model relates to the technical field of grounding devices, in particular to an iron tower grounding device for a booster station. Background Art

[0002] As the country places increasing emphasis on the development of new energy technologies, the requirements for these technologies are also becoming increasingly stringent. The grid-connected power generation and integration of new energy sources is a crucial component of this implementation. Photovoltaic power stations absorb solar energy through polycrystalline silicon solar panels, which are then fed into inverters via photovoltaic modules. This energy is then fed into the grid through the booster station's output. Within the booster station, towers, as crucial power facilities, are crucial for the design of their grounding systems. Tall towers are vulnerable to lightning strikes. When lightning strikes a tower, it generates high voltage and current. These currents surge downward, easily generating large step voltages near the tower, posing a threat to personal safety. Therefore, to prevent lightning damage to the tower and the surrounding environment, a well-designed grounding system is essential.

[0003] Existing tower grounding systems typically use steel plates and conductive wires welded to the lower end of the tower. This method is cumbersome to operate. Furthermore, over extended use, the steel plates, inserted into the ground, are susceptible to soil corrosion, increasing grounding resistance and compromising grounding effectiveness. Furthermore, the steel plates are easily exposed by rainwater, potentially causing the grounding system to fail and posing a threat to the tower's safe operation.

[0004] Therefore, the present application proposes a tower grounding device for a booster station to solve the above problems. Utility Model Content
