For the smart grid industry, the distribution automation system market has become its most important market throughout the industry and even globally. In recent years, advanced measurement infrastructure and demand response have become the darling of the industry, but now the industry has turned its attention to improving the efficiency and control of the grid transmission network between substations and meters.
In addition to these real benefits of improving the reliability and efficiency of grid operations, the implementation and upgrading of distribution automation systems has another important role: high return on investment, and does not require extensive user involvement or behavior change. In short, the industry is increasingly focusing on giving higher distribution intelligence and control capabilities to its distribution infrastructure.
Sovereign investment plans focus on capacity expansion in the emerging markets, the upgrading of aging transmission and distribution infrastructures, and the improvement of reliability and efficiency.
“Electric utilities are facing the challenge of providing a higher level of service to their customers while enjoying a good return on investment, so the continued demand for more energy in the world has driven the development of the market for power distribution automation systems. These challenges have contributed to energy saving. The demand (especially the energy lost in the distribution network), delayed the construction of new power generation facilities and improved customer service, said Steve Clouther, author of the ARC "Power Distribution Automation System Market Research Report."
Distribution Automation System Suppliers
In general, despite the relatively short distribution network distribution network, such as the distribution of electricity from the distribution station to the user's distribution network, but the distribution automation system market participants have diversified, market share leader Each is different.
The leaders in the global distribution automation system market are subsidiaries or divisions of large multinational control companies that have a wide range of operations worldwide. The top ten suppliers occupied 71% of the global market in 2011.
At the 2011 Smart Grid International Forum held in October 2011, State Grid Corporation of China announced that it plans to invest US$250 billion in power infrastructure upgrades over the next five years, of which US$45 billion will be dedicated to smart grid technology. According to its three-phase plan, China will invest a further US$240 billion (including US$45 billion in special funds for smart grid technology) between 2016 and 2020 to complete the construction of “stronger and more intelligent†China Power Grid. .
China will become a driving force for distribution automation
According to the 2011 annual report “World Energy Outlook 2011†issued by the International Energy Agency (IEA), China will surpass the United States in 2015 and become the country with the largest total power generation. By 2035, China will consume nearly 70% more energy than the United States. With the explosive growth of China's energy consumption, China leads the development of distribution automation.
PEEK Plastics,Polyether ether ketone, known in English as polyetheretherketone plastic (PEEK Plastics), is a linear aromatic polymer containing chain sections in the main chain of molecules.Its constituent units are oxygen-pairs of phenyl-oxycarbonyl - pairs of phenyl, semi-crystalline, thermoplastics.
Product name: polyether ether ketone (PEEK Plastics) resin is a kind of excellent special engineering plastics, PEEK Plastics has more significant advantages compared with other special engineering plastics, resistance to high temperature is 260 degrees, mechanical performance, good self-lubrication, resistance to chemical corrosion, flame retardant, stripping resistance, abrasion resistance, no strong sulfuric acid, nitric acid resistance, radiation resistance, strong mechanical properties can be used for high-end technology such as mechanical, nuclear engineering and aviation.
PEEK Plastics has heat resistance, chemical stability and the forming process of thermoplastic plastic. PEEK Plastics has excellent heat resistance.Its thermal deformation temperature of 160 ℃, with 20% ~ 30% Glass Fiber reinforced, heat distortion temperature can be increased to 280 ~ 300 ℃.Polyether ether ketone is good, the thermal stability of 420 ℃ in air.2 h under weightlessness is only 2%, at 500 ℃ was 2.5%, significantly thermo-gravimetric 500 ℃.Polyether ether ketone of long-term use of temperature is about 200 ℃, under this temperature, still can keep the high tensile strength and bending modulus, PEEK Plastics is also a kind of very strong material, has excellent resistance to creep and fatigue performance for a long time.
PEEK Plastics electrical insulating performance is very excellent, volume resistivity of about 10 ~ 10 Ω · cm.It still has small dielectric constant and dielectric loss in high frequency range.For example, in 10Hz, the dielectric constant in the room is only 3.2 and the dielectric loss is only 0.02.
The chemical stability of polyether ether ketone is also very good. In addition to concentrated sulfuric acid, almost any chemical reagent is very stable, even at high temperature, PEEK Plastics can maintain good chemical stability.In addition, PEEK Plastics has excellent heat resistance and steam resistance.In 200 ~ 250 ℃ steam can be used for a long time.
PEEK Plastics with good flame retardancy, in normal circumstances it is difficult to burn, even burning, smoke and harmful gas release a quantity to also is very low, even lower than low smoke volume of polymer such as ptfe.In addition, PEEK Plastics has excellent radiation resistance.Its resistance to alpha rays, beta gamma rays and gamma rays is the best current polymer material.The wire products covered with it can withstand gamma rays of 1.1 x 10Gy.
The polyether ether ketone has good fluidity and thermal stability at the melting point.Therefore, PEEK Plastics has the typical processing performance of thermoplastic plastic. Therefore, it can be used for injection molding, extrusion, blow molding and laminating, and also spinning and making films.Although the polyether ether ketone melt processing temperature range is 360 ~ 360 ℃, but because of its thermal decomposition temperature above 520 ℃, and it still has the very wide processing temperature range.
Although the development history of PEEK Plastics is only a short 20 years, but because PEEK Plastics has the outstanding heat resistance, chemical corrosion resistance, radiation resistance and high strength, easy to machining, PEEK Plastics is currently in the nuclear industry, chemical industry, electronic appliances, machinery, instrument, automobile industry, and has been widely used in aerospace field.In particular, thermoplastic resin, which is excellent in heat resistance, can be used as the base material of high performance composite materials.
modified
PEEK Plastics performance of the pure material is difficult to meet the different needs of different industries, in special working environment need to modification of PEEK Plastics, its main means blending modification, copolymerization modification, reinforced composite, infill modification, nanometer modification and surface modification technology.The modification can increase the performance of PEEK Plastics, such as wear resistance, impact strength, etc., thereby extending the application range of PEEK Plastics, reducing the cost of materials and improving the processing performance of PEEK Plastics.
Application
PEEK Plastics has been widely used in aerospace, automotive manufacturing, electronics, medical and food processing.
PEEK Plastics has excellent performance, its application field will be more widely with the domestic application research, the current domestic set up the chongqing sanxin materials research center is a professional engaged in the research of PEEK in the field of application.The research center is under the chongqing government entities at all levels of leadership and care, is committed to in the field of automobile, electrical and electronic fields, transportation research, in the present walk at the forefront of the domestic application research.
