MGaN-UPDMEWS - Digital Mine

AS

Online insulation condition monitoring and fault early warning for key power supply equipment such as high-voltage switchgears, cable lines, transformers, and power distribution cabinets in underground and surface mines (coal mines, metal mines, etc.).

SA

Suitable for explosive underground mine environments and surface substations, especially for safety monitoring of power supply equipment in harsh industrial environments such as high humidity, dust, and strong electromagnetic interference.

IPP

Traditional monitoring methods have low sensitivity and cannot provide early warning. Adopting GaN ultraviolet sensing technology, the sensitivity is increased by 10,000 times, enabling capture of weak discharge signals in the early stage of insulation degradation (10-15 days before accidents) to realize advanced fault warning.

Strong interference in underground environments leads to inaccurate monitoring data and high false/missed alarms. GaN chips have strong anti-electromagnetic and noise interference capabilities, ensuring accurate and stable data in high-interference environments, effectively solving the industry pain points of false and missed alarms.

Difficulty in locating fault points and time-consuming troubleshooting. The system supports real-time monitoring and trend analysis of multiple parameters such as partial discharge, temperature, and humidity, enabling precise positioning of faulty equipment and even specific fault points, greatly shortening troubleshooting time.

O&M relies on manual inspection, which is inefficient and has safety risks. A fully automatic intelligent monitoring network of "surface monitoring center + underground monitoring nodes" is built to realize 7×24-hour unmanned continuous monitoring and mobile O&M via mobile phones, improving efficiency and ensuring personnel safety.

1. GaN Ultraviolet Sensing, 10,000x Sensitivity
Adopting third-generation semiconductor GaN sensing chips, it is extremely sensitive to ultraviolet signals. The monitoring sensitivity reaches the picocoulomb (pC) level, far exceeding traditional methods such as ultrasound and transient earth voltage, realizing true early warning.

2. Multi-parameter Fusion Perception, Comprehensive Diagnosis
It not only monitors partial discharge but also integrates temperature and humidity sensors, comprehensively judging the equipment insulation status and operating environment from multiple dimensions, providing a more comprehensive basis for fault diagnosis.

3. Strong Anti-interference Ability, Adaptable to Harsh Environments
The sensing technology and system design are optimized for the mine's high humidity, dust, vibration, and strong electromagnetic environments, immune to interference, ensuring long-term stable and reliable operation under extreme conditions.

4. Intelligent Analysis and Visualized Management & Control
The surface monitoring platform has functions of intelligent data analysis, trend prediction, graphical display, and one-click report generation, realizing intuitive management and scientific decision-making of equipment health status.
