Deployment Of Surge Arresters In The Power System Of Charging Piles

As part of the power system, lighting arrester 33kv works in conjunction with the grounding system to guide abnormal currents along a low-resistance path to the ground, thereby reducing the overvoltage amplitude in the power supply line. The power network to which the charging pile is connected adopts a multi-level protection framework. The lightning arrester 20 kv is usually installed at the power inlet and local location of the equipment, forming a network that works in conjunction with other surge protection devices.

In actual deployment, power engineers will select the type and level of lightning arrester 22kv based on the frequency of lightning activity at the site, the power supply level, and the degree of environmental exposure. The high-discharge-capacity lightning arrester 24kv is adapted to the main power supply circuit, while the auxiliary protection device is located in the distribution circuit or equipment end to reduce the impact of lightning events on the internal circuit of the charging system.
