Application of SF6 leakage monitoring and alarm sy

Recently, Wevers Inspection installed SF6 leak monitoring and alarm system in Maanshan 110kv substation of Jiangxi Electric Power Company in Jingdezhen, Jiangxi Province. Wevers SF6 leak monitoring and alarm system plays a key role in the normal operation of substation power equipment and personnel safety.

With the expansion of Jingdezhen's urban framework and the continuous development of its economy, the power load in the central area of the city keeps rising. Because there are no power points in the central area of the city, the power supply is supplied by substations around the city, resulting in too long power supply radius and poor power supply reliability. The completion and operation of the 110KV Maanshan power transmission and transformation project not only provides a strong and reliable power supply support point for Jingdezhen urban center, but also effectively solves the power supply bottleneck problem in Jingdezhen urban center. It is important to improve Jingdezhen urban power supply grid and improve the reliability of urban power supply. To maximize the satisfaction of urban businesses, residential electricity plays a pivotal and irreplaceable role.

The GIS room of the power station adopts Weavers SF6 leakage monitoring and alarm system, which is a comprehensive solution for on-site SF6 concentration, oxygen content and temperature and humidity monitoring. Provides both real-time alarm and data store query functions. The simple operation panel of the system and the LCD dynamic display make it easy for users to master all the operation and use of the system. The gas concentration state at the GIS equipment is monitored in a real-time and dynamic manner. The organic combination of the entire system leaves the user with minimal maintenance steps and costs. The system monitors the environment dynamics of GIS switch room 24 hours a day and creates a good safe environment for GIIS switch room.

SF6 leak monitoring and alarm system is an open system platform which uses the advanced dual-beam infrared detection technology and electrochemical technology of WINFOSS company in Switzerland, and integrates data acquisition, data analysis and processing, and communication technology. The whole system adopts modular design to facilitate engineering installation and engineering maintenance. In the case of complete transmission conditions, a monitoring center can be set up relying on the network. In the remote monitoring center, environmental quantities such as temperature, humidity, oxygen content and SF6 gas leakage can be mastered at any time in the GIS switch room of the bottom substation. Thus, it can improve the management efficiency and perfect the maintenance system of unattended substation and GIS switch room. With the database as the core, the monitoring center can not only monitor the substation and switch room environment and equipment operating status in real time, but also carry out statistics and analysis according to the previous environment and equipment operating data to provide decision-making basis for managers.
