Application of Sulfur Hexafluoride Sensor in Electric Power Industry
With the rapid development of power transmission and distribution circuits from the country to the voltage level, and the continuous increase of GIS and other combined electrical appliances, the amount of sulfur hexafluoride in the power system is gradually increasing. Sulfur hexafluoride (SF6) is an artificial inert gas mainly used in the power industry. It has many advantages and is a colorless, odorless, non-toxic, non-flammable inert gas. Since the mid-1960s, sulfur hexafluoride has been widely used as an insulating medium for high-voltage electrical equipment. Sulfur hexafluoride gas-insulated fully enclosed switchgear has a much smaller footprint than conventional open-type high-voltage power distribution devices, and its operation is not affected by external weather and environmental conditions, so it is not only widely used in ultra-high voltage and UHV The power system can also be used in the distribution network. Although sulfur hexafluoride gas has good insulation and arc extinguishing performance, it has been fully utilized in the field of high-voltage electrical switchgear in substations. However, it also has certain shortcomings. During arc discharge, some low fluoride containing sulfur will be generated due to strong arc discharge, and it has corrosive effect on some insulating materials and metals. Because there are certain differences in the manufacture and installation of high-voltage electrical switchgear, and the phenomenon of product material aging after a long time of use, there is a gas leakage phenomenon in the production and operation of sulphur hexafluoride high-voltage electrical switchgear , This will affect the normal operation of the equipment, and also bring certain safety hazards to the personal safety of the staff. Once the sulfur hexafluoride leaks in this situation, the arc generated during the switching process of the equipment after commissioning will result in the formation of many fluorides and sulfides in the enclosed high-voltage power equipment cavity. Most of these fluorides and sulfides are toxic or even highly toxic. Although they will be quickly synthesized and reduced back to the original gas after the arc is extinguished, there is still a considerable proportion of chemical mixed and toxic gases produced. These toxic gases mainly damage the respiratory system of the human body. After being poisoned, adverse reactions such as colds, skin allergies, vomiting, and exhaustion will occur, which can cause death in serious cases. So when using sulfur hexafluoride gas, special attention should be paid to the monitoring and prevention of sulfur hexafluoride gas. It is necessary to install an online monitoring and alarm system for sulfur hexafluoride leakage. RS-SF6*-N01-2/OLED sulfur hexafluoride sensor is mainly used to monitor the sulfur hexafluoride gas content in the ambient air. It adopts high-quality gas sensor chip, the range is 0~1000ppm, and the measurement accuracy can reach within ±3% FS , Repeatability can reach within 2%. It has the characteristics of quick and sensitive response and strong anti-interference ability. After standard gas calibration, it has the characteristics of long life, high precision, high repeatability and high stability. A device with a high-quality OLED display is also optional. The value can be viewed directly on site and can be displayed clearly at night. The product adopts a wall-mounted waterproof shell, which is easy to install and has a high degree of protection, which can be used in harsh on-site environments. The device adopts 485 signal output, standard Modbus-RTU communication protocol, ModBus address can be set, baud rate can be changed, and the communication distance is up to 2000 meters. Data can be uploaded to our free cloud platform by connecting to the environmental monitoring host. When the sulfur hexafluoride gas content in the environment exceeds the standard, a real-time alarm can be issued. Support multiple data viewing methods on computer web terminal, mobile APP and official account.
