May 3, Pingnan Group, Henan commitment, 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 scientific and technological projects, passed the expert group acceptance. GLW2-252 / T4000-50 integrated intelligent isolation circuit breaker integrates grounding switch, pure optical fiber current transformer, intelligent module, real-time on-line monitoring device, greatly simplifying the system design and wiring, optimizing maintenance strategy, reducing the proportion of Land area and power equipment usage, simplifying plant design, reducing equipment failure rate. Acceptance expert group believes that the intelligent isolation circuit breaker with advanced, reliable, integrated, low carbon, environmental protection, etc., with the intelligent substation required measurement digitization, control network, status visualization, functional integration and information interaction. A new generation of smart isolation circuit breaker is the current power market in China's hot commodity. In response to the project research project more difficult and span a long time, Ping Gao Group organization Bingqiangqiang units in the joint efforts, successfully completed the "126 / 252kV isolated circuit breaker key technology research and product development," "35kV investment Research and development of key technologies of 10 ~ 35kV fast intelligent switch ", a total of 18 test prototypes were written, 30 technical reports were written, 22 were applied for patents, and 20 were published. Articles, the formation of two national grid enterprise standards. Most of the technical achievements of the project research have been successfully applied in production, and some of the products have been put into operation on the State Grid and have produced considerable economic benefits. The research results of this project have broken the technology monopoly of foreign enterprises, filled the technical gaps in the domestic switch field and provided strong support for the construction of the national power grid.
Swivel Flange consist of a forged outer ring, a heavy forged welding hub and a gasket.
The hub can be rotated when the flange is installed.
Swivel flange is also named swivel ring flange.
The flange assembly provides easy alignment of the bolt holes during makeup to a WN flange or other flange.
The swivel flange cover 300#(1/2" to 48"), 600#(8" to 36"), 900#(8" to 36"), 1500#(8" to 24").
The material for them include A105, A350LF2, A694 F65....
