Introduction:
- A DC surge protector is an electrical protection device specifically designed for DC power systems; its function is to suppress and dissipate sudden transient overvoltages (known as “surges”) within DC circuits, while simultaneously blocking excessive surge currents.
- The working principle of a DC DC SPD 2 Pole involves surge detection, rapid response, energy dissipation, and restoration to a normal state.
- The DC DC SPD 2 Pole manufactured by CNTN Electric are widely utilized in applications such as High-Voltage Direct Current (HVDC) transmission systems, the new energy sector (e.g., the DC side of photovoltaic inverters and energy storage systems), DC charging stations, and DC power supply networks for rail transit.
