       sunel said UHV power grid since the power of the future, China should be shipped to Europe to become a reality. Accounting for more than 40% in Xinjiang, where the electricity price is 0.25 yuan per kilowatt-hour, if in the the UHVDC country’s coal resources, it can send the 4000 km Road, 2 to the heart of Europe’s traffic and transportation costs over two hair , or even every kilowatt-hour count of the U.S. dollar is also quite affordable.
According to the progress of the work, China’s northeast, north and other parts of the combination to meet the needs of the development, and to facilitate the transmission of electricity from neighboring countries of Russia, Mongolia, Liaoning, Tianjin, Shandong, DC transmission project construction direction.

Smart Transformers: intelligent solid-state electronic transformer prototype, developed by the Electric Power Research Institute. Smaller than today’s transformers and versatile.
The transformer Today is a single function device. Changing the voltage changes from one level to another, for example, from a high voltage to low voltage, high voltage household 120 volt or 240 volt power distribution level.
New transformers to replace these dedicated charger, and they are more efficient, and only a waste of about four percent of the electricity.
New smart transformers can quickly charge the car, and the power grid to reduce power consumption by 3%, equivalent to the annual U.S. solar panels generating capacity several times.

Transformer generally composed by three parts of the conductive materials, magnetic materials and insulating materials according to their own requirements.
Us to understand the first conductive material, the conductive material of the transformer is a high strength enameled wire, of course, also useful for other materials, that is tuned for use with high frequency transformer yarn envelope.
Second, the magnetic material is all the material properties of the transformer. The power transformer and the magnetic material used in the low frequency transformer silicon steel-based. Intermediate frequency transformers, pulse transformers, oscillation transformer, the use of magnetic materials, Ferrite Magnets-based.
The last means that the transformer insulation materials insulation material In addition to the skeleton, there is a layer of insulation and impregnated materials (insulating paint).
Overall, the quality and grade of the material determines the quality grade of the transformer.

sunel analysis：What can not erase the allowed time goes? And what is the history of the development of the industry left a red-letter? There is what sounded the alarm must always keep in mind for future development?
From the implementation of the recovery growth of the electrical industry,transformer  to like riding on a “roller coaster” of new energy, started energy saving warfare transformer industry.
The steady development of the electric power industry, China’s national economy continued to provide powerful energy support rapid growth and continuous improvement of people’s living standards.
The main products of the key statistical monitoring of the China Electrical Equipment Industrial Association, transformer more than 90% of the products have achieved year-on-year growth.
Mode of economic development of electrical industry are still problems, transformer especially the existence of low-end products overcapacity while the production capacity of high-end products in the industry, such as the lower end of the wire and cable industry producing a serious surplus of high-end products, but shortage of supply and demand.
The drawbacks of the import of used electrical products have become increasingly prominent, strictly limited, strict regulation is imminent.

Safe and efficient amorphous alloy transformer whether to stand out in this wave? This depends on the determination and the market capacity of the grid company.
Compared to ordinary transformer, amorphous alloy transformer with a fully enclosed structure, can delay the aging of transformer oil and insulating paper, not only compact, but also has the advantages of high operating efficiency, maintenance-free. Amorphous alloy transformer due to the low loss, less heat, low temperature, operational performance is very stable.
Amorphous alloy transformer is widely respected worldwide. The United States, Canada, Mexico, Japan, India, Korea and other countries have a large number of amorphous alloy transformer run in the hanging net.
With the increasing of the importance of energy-saving emission reduction, the use of amorphous alloy transformer in recent years has begun to show rapid upward trend.
2012 new distribution transformers all use energy-efficient distribution transformers, promote energy conservation and faster distribution transformer applications.

Traction transformer is electrified railway traction transformer based on the AT power supply dedicated one of its unique structure to achieve the symmetry of three-phase current of the power system to withstand the traction network of proximal and distal frequent short-circuit capacity, and ensure that the electric locomotive safetyrunning smoothly, and to dramatically reduce energy consumption and pressure drop of the traction network.
This type of transformer has been applied in China’s electrified railway is an important equipment of the future high-speed railway in China and the development of passenger dedicated line needed for the building. Scott traction transformer series of products with small size, low cost, high efficiency, maintenance-free characteristics, can effectively reduce the cost of substation construction, has reached domestic leading level.

The isolation transformer generally refers to a 1:1 transformer. Secondary and Ground. There is no potential difference between the secondary any one line and ground.Safe to use. Commonly used for the maintenance of power.
Control transformer and the power of the vacuum tube equipment is also isolation transformer. Such as tube amplifiers, tube radio, and an oscilloscope and lathe control transformer power transformer isolation.
    Isolation transformer first need to understand the power supply system in China, China’s power supply system in the supply of low-voltage users, in general, three-phase four-wire system, neutral ground, popular, that is, to the wires of the residents of the home, a phase line (FireWire), another root of the zero line, it is the same position and the earth, due to touch the hot bottom plate, the body will make the current through the human body and the earth constitute a loop, resulting in electric shock hazard, if you use an isolation transformer, will be safer, because the primary and secondary exchange energy through the magnetic field, there is no hard-wired on the physical, even if human contact with live items, also because the human body and the earth the same position, leaving live parts of the potential for low can cause electrical shock hazards. Use an isolation transformer to pay attention to two points.
