The Taotang 220KV substation of Linfen Power Supply Company is located 1 km southeast of Zhou Village, Shizhuang Township, Huozhou City, Shanxi Province. The Taotang 220KV Substation of Linfen Power Supply Company covers an area of ​​16.68 acres and has two 180,000 kVA main transformers. The operation of this station not only meets the needs of industrial and agricultural production and people's living electricity in Huozhou City, Fenxi County and surrounding areas, but also makes the grid structure of the power grid more reasonable, and also provides reliable power for the Daxi Electric Railway.

SF6 gas is a colorless, odorless, inert gas with a density much heavier than air, and is not toxic to the human body. However, under the action of high-voltage arc, SF6 gas will be partially decomposed, and its decomposition products are often highly toxic. Even trace amounts can cause serious damage to the human body, especially the respiratory system. In the long run, it is easy to cause some chronic diseases due to the poisoning of local tissues. When the indoor switch using SF6 gas as insulation and arc extinguishing medium leaks during use, the leaked SF6 gas and its decomposition products will accumulate in the lower indoor space, causing local hypoxia and poisoning, which is harmful to the staff who enter the room. serious hazard to human health. At the same time, the leakage of gas in the SF6 switch also directly affects the operation safety of the switch. Therefore, with reference to the spirit of the "GB/T8905-1996 Guidelines for Gas Management and Inspection in Electrical Equipment of Sulfur Hexafluoride" and "DL 408-91 Electrical Safety Work Regulations", each SF6 gas user, especially when using a large amount of SF6 gas It is necessary to use equipment and facilities with SF6 concentration and oxygen content monitoring, alarm and control functions to ensure the double protection of SF6 switch equipment and personal safety. WINFOSS S1 type SF6 concentration online monitoring system just meets this demand of electric power safety production, so it can be widely used in electric power users all over the world. 
 
And SF6 high-voltage electrical equipment will have SF6 gas damp phenomenon during manufacture and operation, which directly affects the insulation performance of the equipment, and in severe cases will lead to equipment discharge, short circuit and other vicious accidents. Therefore, the State Grid operation regulations stipulate that the density and water content of SF6 gas must be regularly tested before and during the operation of the equipment. 
 
Weavers signed the installation and construction contract of SF6 density micro-water monitoring system and SF6 concentration online monitoring system with Linfen Power Supply Company in March 2012. After the company's customer service department received the engineering task issued by the engineering project department, the customer service department immediately responded to dispatch Professional installation technical service personnel went to the construction site to carry out the construction. After working hard day and night, all equipment installation tasks were successfully completed. The successful installation of the system effectively guaranteed the personal safety of the environmental personnel and equipment of the substation, and made the entire substation environment and indoor environment. Take running to the next level.
