In order to build a green and conservation-oriented city and earnestly implement the national requirements for clean energy use, some cities have vigorously promoted the application of new energy vehicles. With the popularity of electric vehicles, this undoubtedly promoted the development of automotive charging piles. At present, there are 3,600 charging and replacement stations and 49,000 public charging stations in China.
The automobile charging pile is mainly used in public buildings. For example, in public buildings, shopping malls, public parking lots, residential community parking lots or charging stations, the input terminals of the automobile charging piles are directly connected to the AC power grid, and can be various models according to different voltage levels. Electric car charging.
In practical use, many charging piles are installed in open-air environments and are inevitably subject to wind, rain, rain and sun. This places high requirements on the safety performance of the charging piles such as waterproof, lightning protection, and leakage prevention.
Take lightning protection, because most of the charging piles are outdoors, they are metal bodies, and the charging piles generally adopt high-voltage, high-current working methods. The involved electronic systems, battery modules, and control circuit boards are in the situation. In the thunderstorm weather, in the energized state, it is vulnerable to the impact of induced lightning currents, thereby causing damage to the charging pile equipment, electric vehicles, and personal safety. At this time, a complete system is needed for protection. What do we need to take? Protective measures to ensure safe operation of charging pile equipment?
For the lightning protection of the car charging piles, experts have shown that the special power source lightning protection devices for the car charging piles should be used for protection. Among them, the power source lightning protection device should be applied to the TN-S three-phase five-wire power system and applied to the secondary level of the AC power system. Lightning protection.
In the purchase should pay attention to: Should use low residual voltage, fast response, with a low voltage protection level of the power supply lightning protection device, and should pay attention to the choice of power supply lightning protection device should pass the CQC certification to ensure product quality and safety. During the installation of the power surge protector, the SPD must have a reliable PE ground.
