First, the car charging pile of applications <br> <br> With the number of cars increased gradually, more and more serious global energy crisis, which caused air pollution, global warming, depletion of oil resources and other hazards seriously affected people's daily Production and living. Especially in recent years, major cities and cities have experienced haze of air pollution, which has caused inconvenience to people's production and life. As these hazards become more serious, many automakers are aware of the importance of energy conservation and emission reduction, so electric vehicles have been released and widely used.
The environmental protection of electric vehicles will be the development direction of future automobile production. The increase of electric vehicles has undoubtedly promoted the development of automotive charging piles, which provide power for automobiles as a power source for electric vehicles. At present, various modes have been proposed for charging modes, such as rapid replacement of battery packs, rapid charging, and regular charging. . According to the actual situation, the power battery is bulky and heavy, and it is inconvenient to replace it at will. At the same time, the high-power DC charging cabinet, as an emergency charging device, can provide fast cruising power for the electric vehicle, but has great damage to the battery.
Therefore, the AC charging pile solves the problem of electric energy recharging anytime anywhere in the electric vehicle. The entire vehicle can be charged by directly connecting the charging cable to the charging pile. At the same time, electric energy is supplied in the form of alternating current, which has no harm to the battery and improves the power of the electric vehicle. Battery life is also a good daily charging method for electric vehicles. General layout in the community, office buildings, supermarket parking lot and electric vehicle charging station.
Second, automotive charging pile lightning protection <br> Outdoors, the power supply line is vulnerable to the impact of induced lightning currents.
If the induced lightning invades the charging pile through the line, the charging pile will not be damaged, resulting in the vehicle cannot be charged normally. Furthermore, if the car is being charged, then a lightning strike will cause the vehicle to be damaged and even have more serious consequences. Therefore, the previous lightning safety maintenance is very necessary.
Third, the car charging pile response <br> <br> car charging pile for lightning protection, electrical Kejia developed a suitable vehicle charging pile 40kA C-level modular power mine NKP-DY-II-40/ 385 /4P surge protector, which is designed in accordance with GB18802.1 lightning protection standard. It is suitable for TN-S three-phase five-wire power system. The maximum discharge current of each module can reach 40kA. It is applied to secondary lightning protection of AC power system. protection.
At the same time, the power source lightning arrester has CQC certification and adopts pluggable modular structure design. It has the characteristics of long service life, fast response speed, and ultra-low voltage protection level. It adopts standard guide rail installation and is simple and easy to maintain, ensuring that the car charging pile is free Damaged by lightning.
More lightning protection products can focus on Kejia Electric. . Cn
