Weavers - State Grid Sichuan Province Electric Pow

GB/T8905-1996 "Guidelines for Gas Management and Detection in sulfur hexafluoride Electrical Equipment" and DL 408— 1991 "Electrical Safety Work Regulations" (electrical parts of power plants and substations) and "Eighteen Major Anti-accident Measures of the State Grid Company" specifically stipulate that 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, The oxygen meter and SF6 gas concentration detector must be installed.

Recently, Weavers cooperated with State Grid Sichuan Power Company to upgrade and transform part of the SF6 leakage monitoring system of Guangyuan Power Bureau and replace the original abnormal products. After the successful installation of Weavers SF6 leakage monitoring system, it passed the inspection and acceptance of relevant leaders of State Grid Sichuan Guangyuan Power Bureau. The products have won the satisfactory recognition and unanimous praise from the leaders of Guangyuan Power Bureau for the renovation project.

State Grid Sichuan Electric Power Company, Guangyuan Xixi 110KV substation, Nanhe 110KV substation, Jiuhua 110KV substation and other substations are located in Guangyuan City, Sichuan Province, providing strong power support for the economic development needs of Guangyuan region.

Some SF6 leakage monitoring system of Guangyuan Power Bureau, after several years of operation of the installed system, frequently appeared false alarm monitoring, black screen of death and other problems, and could not be repaired, seriously affecting the entire substation and personal safety. Therefore, State Grid Sichuan Electric Power Company conducted a tender to purchase 6 sets of SF6 leakage monitoring system from Weavers Detection Technology (Shanghai) Co., LTD.

After Guangyuan Electric Power Bureau determined the specific time for renovation and installation, Weavers immediately sent professional and technical personnel to survey the substation one by one and formulate a detailed reconstruction construction plan; And according to each substation booking plan working time arrangement, successfully completed the system transformation work.

Weavers' SF6 leak monitoring system, when installed, has a clear advantage over the plant's older system. It can control the upper and lower fans in the switch (GIS) room, automatically control the fan when a leak occurs or the oxygen level is too low, and automatically control the fan to stop pumping air when the ambient concentration returns to normal. The adopted SF6 and oxygen monitoring unit has dual monitoring functions of SF6 leakage concentration and oxygen content. On the one hand, it has the advantages of making the site structure clear, beautiful layout, and improving the convenience of later maintenance. On the other hand, the dual detection function of SF6 concentration and oxygen can play a double insurance detection advantage for any detection position, and more effectively ensure that technicians are protected by safety tips and personal protection in any environment.

The Sichuan Provincial Electric Power Company's transformation projects of Guangyuan Xixi 110KV substation, Nanhe 110KV substation and Jiuhua 110KV substation have achieved complete success. Weavers and Sichuan Provincial Electric Power Company are looking forward to further cooperation and efforts for the development of Sichuan electric power.
