Protection & Control System - Intelligent Early Warning
Critical Issue: 1 Hour of Underground Shutdown = Hundreds of Thousands in Losses! When underground power is interrupted, mining equipment halts, ventilation fails, and drainage pumps stop. This not only causes massive economic loss but can trigger safety incidents like gas accumulation and flooding.
The HENTG POWER KBSG Series features a "Comprehensive Protection + Intelligent Monitoring" system that blocks faults in real-time and warns of hidden dangers in advance.
Overload Protection: Automatically limits current when load exceeds 1.2x rated value; triggers shutdown at 1.5x to protect core components
Short Circuit Protection: Features instantaneous trip device - cuts power within 0.1 seconds of line short circuit
Over-temperature Protection: Built-in PT100 sensors monitor coil temperature with warnings at >135℃ and automatic shutdown at >150℃
Leakage Lockout Protection: Immediately locks power supply upon detecting line leakage
Voltage Protection: Adjusts output or shuts down if voltage fluctuates >±10%
2. Intelligent Monitoring: Remote Status Mastery
Real-time Data Collection: Uploads voltage, current, temperature, and load rate data via RS485 interface
Fault Warning Push: Detects abnormalities and pushes alerts via SMS/APP/Central Control 24-48 hours in advance
Historical Data Tracing: Automatically stores operating data for more than 1 year for retrospective analysis
3. Stability & Anti-Interference
EMC design resists electromagnetic interference from heavy mining equipment and high-voltage switches. Rugged control module housed in IP65 waterproof/dustproof shell.
4. Maintenance Efficiency: Fast Fault Location
Visual Diagnostics: High-definition display shows fault types and specific locations
Remote Reset: Allows remote resetting of minor faults via central control system
