product description

Installation is based on Chapter 8 of "DL408-1991 Electrical Safety Work Regulations (Electrical Parts of Power Plants and Substations)" and Chapter 4 of "DLT 639-1997 Safety Protection Rules for Operation, Testing and Maintenance of Sulphur Hexafluoride Electrical Equipment" Requirements and "JBT 10893-2008 High-voltage combined electrical distribution room sulfur hexafluoride environmental monitoring system" requirements. Among them, it is specially stipulated in the "Safety Work Regulations for the Electric Power Industry" (for power plants and substations) that the power distribution equipment room equipped with SF6 equipment must ensure that the concentration of SF6 gas is less than 1000ppm. Oxygen meter and SF6 gas concentration monitoring alarm and so on.

SF6 leakage online monitoring and alarm system (WINFOSS-S1) is specially designed for SF6 switch stations of various voltage levels in the power system. It is a comprehensive monitoring and alarm system that integrates the monitoring functions of SF6 concentration and oxygen content in the indoor environment of switch stations. The system has online monitoring of temperature and humidity and fan linkage control functions.
SF6 leakage monitoring and alarm system (WINFOSS-S1) is a comprehensive organic equipment system, which can be used for both on-site local monitoring and synchronous dynamic monitoring on the computer in the main control room; it supports dispatching with on-site remote control devices in the form of hard contacts Remote alarm from the center. In the face of the overall design of SF6 switch station, it can be compatible with the access function of SF6 gas density and micro water online monitoring.

The SF6 monitoring system (WFS-S1P-HO) product is based on the RS485 (MODBUS) bus and DSP technology introduced in the international aerospace fuselage monitoring application, and has strong anti-interference and accurate data quantification platform. Compared with the 485 communication method in the traditional industrial control field, it has higher stability and reliability. The idea of ​​object-oriented design is realized by layered and distributed structure, and the system has convenient and flexible expansion performance. It is an upgraded product of the traditional 485 communication method.

WINFOSS-S1 meets the 4 functional requirements of SF6 industry safety regulations for SF6 substation maintenance management:

A. Hypoxia and SF6 exceeding the standard alarm.

B. When the environment is abnormal, the exhaust function of the fan is controlled jointly.

C. Local display and sound and light alarm prompt at the entrance of the switch room.

D. Define any time period or forced ventilation function.

Applications

WINFOSS-S1 can be used for comprehensive monitoring and control of indoor environment or closed environment in power system (high voltage switch room with different voltage levels of 6KV-1000KV).

A. SF6 high voltage ring main unit switch room.

B. GIS room.

C. SF6 laboratory.

D. Other places where SF6 gas equipment is installed.

The product fully considers the SF6 switch station occasions of various voltage levels; whether it is more than 10 intervals or more than a small-scale substation with only a few intervals of GIS switch rooms, the high-voltage ring network cabinet can be selected for application.

D. Automatic voice prompt: When the staff approaches the entrance of the switch station, the system automatically prompts the environmental safety status in Mandarin, reminding the staff whether it is safe to enter the switch room, and the volume of the voice can be adjusted.
E. Sound and light alarm: When monitoring the concentration of SF6 exceeding the standard or lack of oxygen, the system will prompt the on-site personnel to deal with it in time with a high-frequency whistle and an alarm light.
F. Fan running status indication: Display the current running status of the fan. If it is in a stopped state, it will display the last fan start/stop time, which is convenient for judging whether forced ventilation is required before entering the switch room.

safely control
A. Fan linkage control: When it is detected in real time that the SF6 concentration exceeds the standard ≥1000ppm or the oxygen deficiency is lower than 19.6%, the fan will be automatically controlled to ventilate until the SF6 and oxygen concentrations return to normal, and the fan will be automatically turned off after 10 minutes of continuous ventilation.
B. Fan timing control: Ventilation at custom time periods (up to 24 time periods) to ensure that the switch room can be ventilated on time every day. The ventilation start/stop time can be set flexibly. It can meet the various exhaust needs of users.
