Lightning Arrester Design To Match The Frequency Range Of Charging Pile Network Equipment

The network communication component of charging piles often involves a complex environment where low-voltage DC power supply and communication signals coexist. Its electromagnetic transient spectrum includes not only power frequency components but also high-frequency pulse interference components. The design of the 220 kv lightning arrester must respond to this spectral characteristic in order to achieve good electromagnetic compatibility with the network communication modules and power electronics units of the device.

Considering the specific characteristics of electric vehicle charging stations, it is recommended to analyze the response frequency range of the 33 kv lighting arrester during the product development phase in order to grasp the high-frequency transient components that may occur in the input power supply and communication interface. The design of 33 kv lightning arrester referenced the International Electrotechnical Commission (IEC) and industry standards for testing electromagnetic interference and surge interference to verify the response performance of 33 kv lighting arrester in different frequency bands.
