In the switch room filled with SF6 gas equipment, regardless of the amount of SF6 gas leakage, SF6 online detection and alarm device is required. The SF6 online detection and alarm device mainly detects the SF6 gas content and oxygen content in the ambient air. When the SF6 gas content in the environment exceeds the standard or is hypoxic, it can give a real-time alarm and automatically open the fan for ventilation. And has temperature and humidity detection, working state voice prompt, remote alarm, historical data query and many other rich functions. Its unique trace SF6 gas detection technology can detect 1000ppm concentration of SF6 gas, which can not only achieve the purpose of ensuring personal safety, but also provide more reliable protection for field workers. It can also monitor whether the device is in normal operation.

Industry specific requirements:

SF6 online detection and alarm device in accordance with the "DLT/1555-2016 sulfur hexafluoride gas leakage online monitoring and alarm device Operation and maintenance Guidelines" and "State Grid Company eighteen major anti-accident measures" and "DL408-1991 Electrical safety work Regulations (Power plants and substations electrical part)" Chapter 8 special provisions, The distribution unit room equipped with SF6 equipment must ensure that the SF6 gas concentration is less than 1000ppm, in addition to the installation of strong ventilation devices, must also be installed with alarm oxygen meter and SF6 gas concentration detection and alarm meter.

According to the SF6 Safety Regulations, SF6 online detection and alarm devices must be installed in all households equipped with SF6 gas electrical equipment, and a certain number of oxygen meters and SF6 concentration monitoring collectors must be set up to alarm when the gas concentration exceeds 1000μL/L and the oxygen concentration is less than 18%. In addition, ventilation devices should be installed in the low area of the environment to ensure the personal health and safety protection of the staff in the distribution unit room of SF6 equipment. The device mainly detects the SF6 gas content and oxygen content in the ambient air. When the SF6 gas content exceeds the standard or there is no oxygen in the environment, it can give a real-time alarm and automatically open the ventilator for ventilation. And has temperature and humidity detection, working state voice prompt, remote alarm, historical data query and many other rich functions. The SF6 online detection and alarm device provided by Weavers uses the unique SF6 gas infrared spectroscopy detection technology to detect the minimum SF6 gas content of 50ppm in the environment.

SF6 Safety Regulations Excerpt:

Article 191 Power distribution rooms and SF6 gas laboratories equipped with SF6 equipment must be equipped with powerful ventilation devices. The air outlet should be set in the lower part of the room.

Article 192 In the room, when the equipment is filled with SF6 gas, the relative humidity of the surrounding environment is 80%, and the ventilation system must be turned on to avoid SF6 gas leakage in the working area. The SF6 gas content in the working area air shall not exceed 1000ppm.

Article 196 The staff entering the SF6 distribution unit room must first ventilate for 15MIN, and measure the SF6 gas content with a leak detector, try to avoid one person entering the SF6 distribution unit room for inspection, and no one is allowed to enter the maintenance work.

Article 198 Staff entering the SF6 distribution unit room low area or cable trench to work should first test the oxygen content (not less than 18%) and SF6 gas content is qualified.

Article 199 The oxygen meter and the SF6 gas leakage alarm meter shall be installed in the low area of the SF6 power distribution unit room. These instruments should be tested regularly to ensure their good condition.

Article 203 In the event of an emergency, all ventilation systems shall be opened immediately for ventilation. In the event of a rupture of the equipment's anti-explosion film, it should be treated with power failure and wiped clean with gasoline or acetone.
