Overview
The AC controllable self-recovering energy dissipation device equipped with a lightning arrester. This device utilizes mechanical switches to control the protection characteristics of the lightning arrester, enabling controlled suppression of fault ride-through overvoltage and enhancing the stability of DC systems.
Features
Excellent Residual Voltage Protection Level
It effectively limits the amplitude of overvoltage within a safe range, protecting subsequent equipment from high voltage damage.
High Energy Absorption Capacity
With multiple parallel columns and high current-carrying capacity, it can withstand significant current surges and energy release in a short period, ensuring system stability and safety.
Self-recovery Capability
After the intrusion wave disappears, it can automatically restore its insulation capability, featuring multiple impact energy tolerance characteristics, which helps reduce system failure rates and improves the stability and reliability of power systems.
Compact Structure and Small Footprint
Adopting a compact structure design, it minimizes floor space occupation, facilitating installation and enhancing system integration and operational efficiency.
