500kVA 11kV/0.4kV Explosion Proof Mining Transformer
Designed specifically for underground coal mine power supply
applications, this explosion-proof transformer ensures safe and
stable operation in hazardous industrial environments including
coal mines and metal mines.
Certification & Compliance
Our mining explosion-proof transformers fully comply with mining
industry safety standards and are certified by authoritative bodies
(MA, KA, ATEX depending on market requirements).

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
