SF6 density micro water online monitoring system (Winfoss-S6)

Original imported sensors, precision measurement, high lifespan; patented sealing technology, zero leakage, strong guarantee for the safety of high voltage electrical equipment!


According to "Q_GDW 534-2010 Technical Guidelines for Transformer Equipment On-line Monitoring System", "DLT 1054-2007 High-voltage Electrical Equipment Insulation Technical Supervision Regulations", "QGDW 172-2008 SF6 State Inspection Guide for High-voltage Circuit Breakers", "DLT 846.5- 2004 General Technical Requirements for High-Voltage Test Equipment: Part 5: Sulphur Hexafluoride Trace Moisture Analyzer.

The SF6 density micro-water on-line monitoring system (Winfoss-S6) enables users to access and understand the operating status of each substation more conveniently and anytime. Maintenance and repair personnel can clearly know what they need and what to do. The core of all these scientific and technological achievements is attributed to the micro-water measurement analysis algorithm based on the DRYCAP® detection technology and the digital SF6 gas density monitoring technology. An expert diagnostic system based on digital processing technology (DSP) and real-time database technology. It guarantees accurate changes in the internal gas quality deterioration trend of the switch through dynamic digital pressure and slight water monitoring data changes, and provides scientific basis for users to provide state preventive maintenance. 


The SF6 gas micro-water and density on-line monitoring function of the detected air chamber is realized, and the monitoring unit number, the standard pressure (20° C.), the micro-water value (ppm), the current pressure, the current temperature, and the dew point value are collectively displayed on the server. Density alarm value and blocking value and other parameters.

Monitoring volume limit alarm function.

Monitoring data storage function.

Density micro-water monitoring point any expansion function.

Alarm/lockout value self-adjustment function.

Automatically draws state change trend graphs.

Support data remote transmission function.

User rights management.

Data transmission encryption.

The system complies with the IEC 61850 communication protocol and can interface with other equipment to meet the communication requirements of intelligent digitalized substations in power systems.

Compatible with all switch interfaces at home and abroad.
