Focus on "Protection & Control System" – Intelligent Early Warning, Nip Faults in the Bud
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. Ordinary transformers often lack predictive capabilities, only "shutting down after the fault occurs." The HENTG POWER KBSG Series features a "Comprehensive Protection + Intelligent Monitoring" system. It blocks faults in real-time and warns of hidden dangers in advance, making power faults "visible, preventable, and quickly repairable."
Protection System vs. Ordinary Transformers 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
• 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 an instantaneous trip device. Cuts power within 0.1 seconds of a line short circuit, preventing equipment damage and spark ignition. • Over-temperature Protection: Built-in PT100 sensors monitor coil temperature. Sends warnings at >135℃ and automatically shuts down at >150℃ to prevent insulation failure. • Leakage Lockout Protection: Immediately locks power supply upon detecting line leakage, preventing electric shocks or spark explosions. • Voltage Protection: Adjusts output or shuts down if voltage fluctuates >±10%, protecting precision machinery from damage.
2. Intelligent Monitoring: Remote Status Mastery • Real-time Data Collection: Uploads voltage, current, temperature, and load rate data to the central control system via RS485 interface. • Fault Warning Push: Detecting abnormalities (e.g., slow temp rise), the system pushes alerts via SMS/APP/Central Control 24-48 hours in advance, enabling preventative maintenance. • Historical Data Tracing: Automatically stores operating data for more than 1 year, supporting retrospective analysis after faults (e.g., "correlation between temperature abnormalities and load during a certain period"), helping mining areas optimize power supply schemes and reduce similar faults.
3. Stability & Anti-Interference • EMC Design: Resists electromagnetic interference from heavy mining equipment and high-voltage switches, ensuring protection accuracy ("No delay when action is needed, no misjudgment when it is not"). • Rugged Control Module: Housed in an IP65 waterproof/dustproof shell to withstand humidity and dust.
4. Maintenance Efficiency: Fast Fault Location • Visual Diagnostics: High-definition display intuitively shows fault types (e.g., "Overload," "Leakage") and specific locations (e.g., "Low-voltage side cable"). • Remote Reset: Allows remote resetting of minor faults (like temporary overload warnings) via the central control system, saving maintenance time and reducing underground trips.
