Application of SF6 concentration on-line monitorin

Recently, Miyun Power Supply Bureau Jugezhuang 110KV substation introduced Wefus Detection Technology (Shanghai) Co., Ltd. SF6 concentration online monitoring system (Winfoss-S1) for GIS switch room SF6 real-time monitoring, and achieved the ideal effect.

The SF6 and oxygen monitoring unit used in the SF6 concentration online monitoring system (Winfoss-S1) has the dual monitoring function of SF6 leakage concentration and oxygen content. On the one hand, it has the advantages of making the site structure clear, beautiful layout, and improving the convenience of later maintenance. On the other hand, the dual detection function of SF6 concentration and oxygen can play a double insurance detection advantage for any detection position, and more effectively ensure that technicians are protected by safety tips and personal protection in any environment.

The temperature and humidity monitor configured in this solution has the function of dual detection of ambient temperature and humidity, and real-time monitoring of indoor temperature and humidity on the switch (GIS). When users need to control indoor temperature and humidity, they can control the operation of the dehumidifier, air conditioner or heater installed on the site by expanding the temperature and humidity output contact. It makes the SF6 switch and the oxygen content in the work area in the plant realize real-time automatic comprehensive monitoring and control, and the operating status of the equipment and the gas content in the work area more transparent, effectively guarantees the personal safety of the maintenance personnel and the operation of the GIS equipment, and plays a very important role in preventing accidents.
