In modern power systems, high-voltage switch distribution rooms are crucial components. In order to ensure the safe and reliable operation of power equipment, SF6 monitoring systems play an important role in the maintenance of high-voltage switch equipment. This article will explore the application and importance of SF6 monitoring systems in GIS high-voltage switch distribution rooms.
High-voltage switches are one of the important equipment in power plants and distribution stations. In order to reliably deliver power projects to the state grid, it is necessary to ensure that high-voltage switches and other facilities operate normally and reliably. On high-voltage switch GIS equipment, SF6 maintenance gas density and trace moisture content are key to whether high-voltage switches can operate reliably.
In order to ensure the normal operation of high-voltage switches, it is necessary to ensure that the SF6 density is not less than a certain standard value. Therefore, the SF6 gas density of high-voltage switches must be monitored in real time. In the measurement of SF6 gas density, traditional methods mostly use pointer instruments and rely on on-site staff to obtain data manually. The disadvantage is that the measurement accuracy is poor and the reading is very inconvenient. In addition, incorrect readings may be caused by the carelessness of staff, which is not conducive to the standardized management of observation data. If a leak occurs, and the relative density does not drop to the alarm point, it will be difficult for the relevant staff to detect the leak, which is not conducive to recording the specific time and process of the leak. In serious cases, it may cause a great safety production accident.
In response to the above-mentioned demand for SF6 online monitoring in the high-voltage switch distribution room, the SF6 monitoring system is a design solution for the natural environment SF6, oxygen content, temperature and humidity detection provided in the GIS system workplace to avoid SF6 gas leakage causing low oxygen content and harm to relevant staff.
In the high-voltage switch distribution room, the SF6 monitoring system can provide real-time gas density and humidity monitoring, avoiding the measurement deviation caused by gas release and re-inflation in traditional methods. Through online monitoring, the system can detect gas leakage problems in time and automatically alarm to ensure that timely measures are taken to avoid accidents.
The SF6 monitoring system can accurately measure the gas content and moisture content. Through real-time data monitoring, it can immediately issue an alarm when the gas concentration exceeds the standard or oxygen is insufficient. In addition, the system also has temperature and humidity monitoring functions, which can record environmental changes in real time to ensure the stability of the distribution room environment.
When the SF6 gas concentration is detected to be too high or the oxygen content is too low, the SF6 monitoring system can automatically start the exhaust fan for ventilation to ensure that the gas concentration returns to a safe range. At the same time, the system supports remote alarm function, and the staff can view the status of the distribution room in real time on the remote terminal, further improving safety and work efficiency.
The SF6 monitoring system provides a detailed historical data recording function, allowing users to query past data at any time for analysis and management. This not only helps maintenance personnel track changes in gas concentration, but also provides reliable data support for the long-term operation and maintenance of equipment.
