The Selection Of Surge Arresters Should Meet The Operating Voltage Requirements Of The Charging Pile.

For charging piles connected to mains power or high-voltage power supply systems, lighting arrester 33kv must function within its nominal operating voltage range to match the electrical parameters of the equipment, and must meet the voltage withstand and discharge capability requirements of international standards such as IEC 61643-11 for overvoltage protection components.

In charging networks, transient phenomena such as voltage fluctuations on the mains side and lightning-induced overvoltages can impact internal control systems and power electronics. The maximum continuous operating voltage (Uc) setting of lightning arrester 20 kv must be matched with the rated value of the power supply system so that lightning arrester 22kv can respond to overvoltage events without interfering with normal operation when voltage fluctuations occur.

Different types of lightning arrester 24kv (e.g., devices suitable for both AC and DC circuits) also have different design orientations for voltage matching. For DC fast charging facilities, the operating voltage parameters of the lightning arrester 24kv 10ka should cover the possible high DC voltage range, while AC charging piles need to select components according to the voltage level of the AC network.
