HZ-OLF-100 架空線路故障指示器

Advanced Detection & Warning Capabilities

• Comprehensive Fault Detection: Precisely identifies short-circuit faults, ground faults, poor contact faults, and insulator faults.
• Self-Organizing Network: Features high-level network adaptability, allowing the system to maintain a stable connection through its own architecture from sensing to the management platform.
• Intelligent Warning Types: Provides alerts for crown close-range discharge, floating object contact (excluding plastic), and monitors asynchronous actions in three-phase switches.
• Zero False Alarms: Utilizes a passive sampling mode that operates only when activated by fault current pulses, physically eliminating interference-driven false reports.

• Private Wireless Communication: The system utilizes a 433.92MHz private wireless frequency for data transmission between terminal sensors and substations, eliminating monthly communication fees and vulnerability to public signal outages.

Key Technical Advantages

• Broad Voltage Range: Fully supports transmission and distribution lines from 5kV up to 500kV.
• Long-Range Coverage: Each terminal sensor effectively covers a line distance of up to 5km (3 miles).
• Triple-Source Power Supply: Terminals are powered by solar energy, current-induced power harvesting, and an internal battery for long-term stability.
• Environmental Resilience: Features an IP67 protection rating and operates reliably in temperatures ranging from -25°C to 70°C.
