SF6 gas monitoring and alarm systemalso known asSF6 leakage monitoring and alarm system, SF6 gas online leakage monitoring and alarm device, SF6 gas quantitative monitoring and alarm system, SF6 concentration monitor, SF6 gas leakage monitoring device, SF6 online detection and alarm device, SF6 environment online monitoring system, SF6 concentration online monitoring system, etc.

overview

SF6 gas monitoring and alarm system(Winfoss-S1P)According to《Chapter 8 of DL408-1991 Electricity Safety Work Regulations (Electrical Part of Power Plants and Substations), Chapter 4 of DLT 639-1997 Safety Protection Rules for SF6 Electrical Equipment Operation, Testing and Maintenance Personnel, and JBT 10893-2008 Environmental Monitoring System for SF6 in High Voltage Combination Electrical Equipment Distribution RoomIn the "Electricity Safety Work Regulations" (for power plants and substations), it is specifically stipulated thatThe distribution equipment room of SF6 equipment must ensure that the SF6 gas concentration is less than 1000ppm. In addition to installing strong ventilation devices, it is also necessary to install oxygen meters and SF6 gas concentration monitoring alarm devices that can alarm.

This system is specifically designed for the power systemHigh voltage GIS combination electrical equipment switch rooms and ring main unit distribution rooms with different voltage levels such as 10KV, 35KV, 110KV, 220KV, 500KV, 750KV, as well as workplaces using SF6 gas. The system has a comprehensive monitoring and alarm system for online real-time monitoring of SF6 gas concentration, oxygen content, temperature, and humidity in the environment. It has the function of fan linkage control and uploading monitoring data to the monitoring center platform. To ensure the personal safety of on-site inspection personnel and guarantee the safe operation of SF6 electrical equipment.

The entire system consists of a touch screen LCD monitoring hostThe system consists of SF6 gas and oxygen monitoring unit modules, temperature and humidity monitoring unit modules, human infrared voice sensors, sound and light alarm devices, and fan linkage controllers. It can automatically record various alarm data and real-time online monitoring data, and provides interfaces with remote communication devices to achieve remote control, telemetry, and remote signaling, and control of fans, air conditioners, access control devices, and other devices according to the set method; And all monitoring data can be uploaded to the monitoring platform server.

SF6 leakage detection principle: SF6 gas leakage monitoring adopts non dispersive infrared spectroscopy absorption (NDIR) detection technology. Compared with other detection technologies, it has high detection accuracy, stability and reliability, wide monitoring range, and is not limited by environmental temperature and humidity conditions.

major function

l Real time online monitoring of SF6 concentration and oxygen content in the switch room environment 24 hours a day, 365 days a year. The monitoring host dynamically displays the SF6 concentration and oxygen content values of each monitoring unit in the environment, as well as the current status values of temperature and humidity.

l Real time online monitoring of the current temperature and humidity in the switch room environment 24/7, with the monitoring host dynamically displaying the current status values of various temperatures and humidity in the environment.

l Alarm output: WhenWhen the SF6 gas or oxygen content reaches the alarm concentration, the sound and light alarm device will emit sound and light, voice alarms according to the alarm threshold set by the system, and notify the remote monitoring center through software protocols or dry contacts. At the same time, the fan will automatically start according to the set method.

l The alarm threshold values of the system can be set on the touch LCD monitoring host as required, and the monitoring data can be uploaded to the background monitoring computer for display or various parameters can be set on the background monitoring computer.

l Infrared sensing and voice alarm and prompt: If a staff member approaches the switch room, the infrared sensing of the human body in the operation control screen will be triggered, and the operation control screen will activate the voice prompt to indicate whether the staff member is currently in the roomSF6 leakage exceeding the standard and oxygen concentration status.

l Fan control: There are three ways to start the fan: timed start, alarm start, and forced start; There areThe function of timed start in 8 time periods can be set from 0 to 8 times according to user requirements, and the specific time for each start can be set by oneself; When the SF6 or oxygen concentration reaches the alarm concentration, the system automatically starts the fan for ventilation; The touch screen of the monitoring host interface has icons for switching between automatic and manual fan modes, which can be used to switch between forced fan start stop and automatic fan functions. When the SF6 concentration exceeds the standard by ≥ 1000ppm or the oxygen deficiency is below 19.6% in real-time, the ventilation start/stop time can be flexibly set to meet various exhaust needs of users.
