Wevers-longhua 110kv substation SF6 leakage monito

Longhua 110kv substation of Chengde Power Supply Company is located in Longhua County, Chengde City. In recent years, the power load of Chengde City continues to increase, and the power grid structure has undergone great changes. Therefore, it is very important to ensure the safe operation of the power grid.

The original SF6 concentration leakage monitoring and alarm system used in the substation frequently had problems, such as black screen of death, false alarm and other problems, and the power station reported to the power company for replacement. Gansu Electric Power Company adopted the Weifers SF6 concentration leakage monitoring and alarm system (winfoss-si), which was linked with the upper and lower fans in the switch (GIS) room for control. When leakage occurs or the oxygen content is too low, the fan is automatically controlled to run, and the fan is automatically controlled to stop discharging air until the ambient concentration returns to normal.

Chengde Power Supply Company Longhua 110kv substation purchased two sets of Weavers SF6 leakage monitoring and alarm system. Weavers Inspection immediately sent technicians to carry out on-site survey, and formulated the installation plan. The installation equipment ran normally after commissioning, and the substation staff accepted it.

With flexible composition and unified interface standard, the system can not only meet the current monitoring requirements of the power station, but also facilitate the future expansion compatibility requirements even if the number of SF6 units increases or decreases and other SF6 switch monitoring systems are introduced. The system can be connected with a remote device to realize remote remote alarm. After selecting the configuration of monitoring software or network application software, device drivers can be installed on the monitoring center platform and corresponding communication ports can be configured to realize the monitoring and control of field data on the monitoring center operation platform, which can further improve the efficiency and management level of maintenance work, and provide support for the realization of paperless office and unmanned on-duty of power station maintenance.

SF6 concentration leakage monitoring and alarm system is an open system platform that uses Germany's advanced dual-beam infrared detection technology and electrochemical technology effectively combined with 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 established relying on the network. In the remote monitoring center, environmental quantities such as temperature, humidity, oxygen content and SF6 gas leakage status 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.

The Wevers SF6 leakage monitoring and alarm system and SF6 professional services provided by Wevers for the Longhua 110kv substation of Chengde Power Supply Company have strengthened the safety and reliability of SF6 electrical equipment, ensured the safe operation of the power grid, and played a key role in the optimization of Chengde's power supply.
