How Do Surge Arresters Prevent Surge Voltage Caused By Lightning Strikes From Entering The Charging Station Through The Power Cord?

Charging piles operating outdoors face the threat of transient high voltage from thunderstorms. As a core protective component in electrical systems, the lightning arrester 24kv 10ka can function in the early stages of high-voltage surges, adjusting the abnormal voltage to be released along the ground wire, thereby protecting the power supply link and downstream equipment from severe voltage surges.

When designing a charging pile protection scheme, connecting the lightning surge arrester in parallel to the main power input terminal can quickly guide lightning-induced surges along the path to the grounding system, preventing large voltage fluctuations from propagating to the power electronic modules and control units.

When properly installing surge arresters grounding, attention should be paid to the connection quality with the grounding system and the layout of the conductors. Short and direct grounding conductors help reduce additional voltage drops and induced paths. Appropriately configuring multiple installation points can further adjust the surge characteristics at different stages, ensuring the overall power supply architecture maintains voltage stability even during thunderstorms.
