HM-6000 Online transformer oil chromatography monitoring system
Products Overview
The HM-DGA-6000 Online Monitoring System for Dissolved Gases in Transformer Oil provides high-precision quantification, automatic cleaning, efficient separation, automatic oil return, sample analysis, data processing, and real-time alarms; It rapidly analyzes and monitors the concentration and growth rate of dissolved fault gases in the oil of oil-immersed high-voltage power equipment, such as transformers, and uses a fault diagnosis expert system to provide early warnings of potential equipment failures. This helps prevent equipment accidents, reduce significant losses, and improve the reliability of equipment operation. As a flagship product in the field of online oil gas chromatography monitoring, this device provides a stable and reliable solution for online remote analysis of power transformers and serves as a strong guarantee for the implementation of condition-based maintenance in power systems.
Products features
- Flexible Monitoring Intervals: Minimum 60-minute intervals, with user-configurable settings; 12 hours is recommended.
- Rapid Gas Analysis: Elution and separation completed in approximately 15 minutes.
- Safe Oil Return: Multi-layer isolation and defoaming technology prevents carrier gas from entering the transformer.
- Low Acetylene Detection Limit: C₂H₂ detection limit as low as 0.2–0.5 μL/L.
- High-Precision Temperature Control: Intelligent constant-temperature control with accuracy of ±0.1 °C.
- Integrated Intelligent Control: Combines gas separation, data acquisition, analysis, alarms, and equipment monitoring in one system.
- Strong EMC Performance: EMI/EMC-designed circuits improve resistance to electromagnetic interference.
- Remote Digital Communication: Supports Ethernet and RS485 for remote monitoring, control, and configuration.
- Built-In Fault Diagnosis: Supports the Three-Ratio Method, David Triangle Method, and Cube Diagram Method.
- Remote Maintenance & Self-Diagnostics: Detects equipment abnormalities and supports remote maintenance.
- IEC 61850 Networking: Supports IEC 61850 for integration with other monitoring devices.
- Flexible System Integration: Highly scalable for connection with additional online monitoring equipment.
- Cylinder-Free Zero-Air System: Built-in zero-grade air generation eliminates frequent carrier gas replacement and reduces maintenance requirements.
