GLW2--252 / T4000-50 integrated intelligent isolation circuit breaker integrated with earthing switch, pure fiber current transformer, intelligent module, real-time on-line monitoring device, greatly simplifying the system design and wiring, to optimize the maintenance strategy, reducing the It has the advantages of advanced, reliable, integrated, low-carbon and environmental protection, etc. It has the functions of measurement digitalization, control network, status visualization, function integration and information required by smart substation Interactive function.
For a new generation of intelligent isolation circuit breaker project research project more difficult, span a long time, Pinggao Group completed the "126/252 kV isolated circuit breaker key technology research and product development," "35 kV switching capacitor Group of solid state composite switch development "and many other topics, a total of 18 prototype test, write technical report 30, apply for a patent 22, published 20 papers, the formation of the State Grid Enterprise standards 2. Most of the technical achievements of the project research have been successfully applied in production, and some of the products have been operated on the national grid and have produced considerable economic benefits.
Flat high research and development of new intelligent isolation circuit breaker make up the domestic technology gap
Recently, Ping Gao Group Co., Ltd., China Electric Power Research Institute, State Grid Smart Grid Research Institute and other units to participate in the completion of the "smart break technology research and product development," State Grid Corporation of science and technology research projects, one-off successfully passed the experts Group acceptance. The research results of this project have broken the technical monopoly of foreign enterprises and filled the technical gap in the domestic switch field.
