product description

The SF6 micro-water density online monitoring device (WINFOSS-S6) is mainly used in the online monitoring of high-voltage electrical equipment using SF6 gas insulation in substations. The SF6 micro-water density online monitoring device can monitor the SF6 gas pressure, Density, temperature, dew point and PPM values. And provide SF6 gas moisture exceeded alarm function, density alarm. The data processing server automatically collects and stores monitoring data, and completely preserves the data trend (the data can be preserved for more than 15 years). The data processing server displays and processes the received data, and gives the test results and the change trend curve. The monitoring data and alarm signals can be uploaded to the upper-level monitoring center or the background of the fortune monitoring in real time.

SF6 micro-water density online monitoring device (WINFOSS-S6) transmission monitoring unit integrates three sensors and a micro-circulation system. The SF6 micro-water density online monitoring product in high-voltage switchgear mainly solves the problem of online monitoring of micro-water, temperature and pressure in each gas chamber in a closed gas chamber. It is a digital SF6 gas density and micro-water comprehensive online monitoring and diagnosis system for the condition maintenance of power SF6 switch station.

The digital SF6 gas density and micro water comprehensive online monitoring and diagnosis system includes:

1. Distributed in the urban dispatch center or the remote client of any office desktop computer according to the user's needs (responsible for remote monitoring of the SF6 switch density and micro-water operation status in all substations within the jurisdiction), located in the power distribution cabinet of the main control building of the monitored substation The on-site monitoring server (mainly responsible for centralized data processing, monitoring and unified protocol to facilitate interface compatibility and encryption and decryption of remote transmission), SF6 density micro-water monitoring unit located on each switch body (to realize the gas density, micro-water monitoring unit in the switch body Sampling and data quantification of water and temperature, and complete transmission), a three-in-one integrated intelligent management and diagnosis system is formed for this purpose.
2. On the one hand, the SF6 density micro-water monitoring unit communicates and uploads the collected and quantified SF6 gas density and micro-water content data with the on-site monitoring server through RS485. On the other hand, it will be connected to the relay protection system in the main control room of the substation in the form of passive hard contacts, so that the density and micro-water data of each unit in the switching station can be remotely monitored, and the switching operation trend can be predicted. At the same time, the alarm and blocking protection control of density and sluggish water are linked (users can choose whether they are currently connected or not according to their needs).
3. The on-site monitoring server exchanges data with the host computer or remote computer in the form of power communication protocol or RS485. Realize digital sampling, on-site monitoring, central/main control room monitoring, remote dispatch center synchronous monitoring and management integrated SF6 gas density and micro-water comprehensive online monitoring and status diagnosis system, and regularly output operating status diagnosis report.
