Main challenges faced

Difficulty in Rapid DC Arc Interruption

Difficulty in Rapid DC Arc Interruption

1500V high-voltage DC systems lack natural current zero-crossings, causing conventional breakers to fail in extinguishing arcs promptly, risking sustained arcing.

Multi-System Coordination Delays

Multi-System Coordination Delays

Millisecond-level delays between BMS/EMS/PCS protection signals and breaker actions may miss critical fault interruption windows.

‌Reliability Degradation in Extreme Environments

‌Reliability Degradation in Extreme Environments

Mechanical components face jamming risks and seal failures in desert/arctic conditions.

Scheme Introduction

Centralized photovoltaic power stations have large system configuration capacity, high DC voltage levels, complex application environments, and high requirements for electrical equipment reliability and environmental adaptability.
