Intelligent Protection & Control System
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.
Advanced Protection Features
Functions: Comprehensive (Overload/Short circuit/Temp/Leakage/Voltage)
Early Warning: 24-48 Hours Advance Notice
Monitoring: Remote Real-Time + Historical Tracing
Fault Location: Precise display of Type & Location
Anti-Interference: High resistance to electromagnetic noise
5-Layer Defense System
Comprehensive Fault Protection: Real-Time Risk Blocking
- 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%
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
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.
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
