Wind power industry to accelerate the process of internationalization

China's wind power industry in the domestic market under the strong pull , in a few years time, the rapid growth of the global wind power industry big country . At present, China's wind power [ 3.23% ] industry matured from the exploratory stage , after winning the rapid growth of wind power industry manufacturers gradually accelerate the pace of internationalization of the situation .

Wind trend towards capital to go out

China 's rapid development of wind power market spawned a large number of wind power equipment manufacturing enterprises , also makes the domestic wind power market competition intensifies . Recently released a report pointed out that the domestic wind power machine manufacturing sectors have been hundreds of companies , with domestic rapid growth of wind power installed capacity of wind power machine manufacturers into "Red Sea" , the increasingly fierce price war has begun affect corporate profitability . In this market context, explore new market growth has become a major domestic wind turbine manufacturers an important strategy for future development .

Recently held in Beijing International Wind Energy Conference, China Wind Energy Association Vice President Shi Pengfei said that with China 's rapid development of wind power industry , wind turbines excess capacity , companies are bound to open up the international market. According to Wind Energy Association 's statistics, last year China exported to overseas fans reached 430,000 kilowatts , total exports to foreign markets more than 700,000 kilowatts . Meanwhile, with the improvement of the quality of domestic fans , domestic fans higher price also makes access to international markets accelerated.

According to statistics, in 2012 a total of 19 countries, imports of Chinese fans, which the United States the largest capacity of 328,000 kilowatts , accounting for 47% of China's export machine . Shi Pengfei pointed out that it is not only the machine , parts exports have accounted for a large proportion, even more than the overall export even earlier . Like the first tower , castings , etc., although some quality and technical level is not particularly high, but competitively priced , so many foreign machine manufacturers are willing to import parts from China .

But this is just the device went out , and now China's wind power capital to go is becoming a trend. For example , Longyuan , Trinity , Tianrun were acquired and invested in Canada, USA, Australia, wind power projects . Another way is through the acquisition of foreign companies to achieve global distribution and introduction of technology, such as the wind holding German VENSYS company Darwind Hunan Electric Group acquired the Dutch company . There is a direct establishment of overseas R & D centers , the use of foreign technology , talent and a wealth of experience in wind power development , through international cooperation, to improve their level . Shi Pengfei , not without emotion, said .

China is the international wind power base

According to the World Wind Energy Association (WWEA) the statistical results , in 2012 the world's new wind power capacity 44GW, China is still a cumulative installed capacity of wind power accounted for 27% of global market share continues to remain the world leader position. World's wind power installed capacity of five countries were China , the United States , Germany, Spain and India.

In China , the world's largest wind power market, the lack of foreign fans never impossible corporate presence. Shi Pengfei, in an interview with reporters , said China's wind power industry in rapid development stage , foreign companies have been the Chinese wind turbine power construction participants. Ten years ago there were only two fan-made brands, the market most of the foreign brands, but now the situation is completely reversed . Even so, like Vestas in the Chinese market each year there are 500,000 kilowatts of the market.

He also pointed out that , in addition to the machine outside , foreign brands of parts or has an absolute advantage. The key components of the fan bearing manufacturer FAG, KF accounted for half of the domestic market , although the domestic bearing manufacturers have been trying , but the domestic wind turbine manufacturers mainly using imported bearings. Others, like converters, control systems and other key components or foreign brands in the market. Also on the advice of wind power , many of the domestic machine factory products are jointly designed and GL . In the wind power plant design software software, our fans are still dependent on foreign enterprises enterprises .

Accelerate the master core technologies to improve competitiveness

On China's wind power industry , the main advantage of the broad market does not exist for a long form , and also appeared at this stage installed capacity decreased gradually . This should focus on high value-added product development, differentiation strategy to promote wind turbine industry development , the realization of China in the global industry value chain to enhance the status . With the economic level and consumption levels increase , with new technology features high-value products will have more wind power vast international market.

Meanwhile, the international implementation and accelerate the pace of the wind power industry to re- scale pull back the economic sphere, once the wind power manufacturers mastered the core technology and products , it may become the industry leader. In the industrial development process , excessive competition in the market will not have the phasing out a large number of backward enterprises a competitive advantage in the industry, the process of integration of acquisitions , the whole industry will tend to focus on those core technologies with independent intellectual property rights and business, will by virtue of the key aspects of the control and monopoly of the core technology to become the industry leader , they will cooperate with each other to form a competitive industry, the integration of wind power , this integration will help our fans exports.

Homogeneity is also China's wind power products is a major drawback , to enhance international competitiveness, we need to implement strategies to differentiate from low-cost strategy to shift the corporate strategy focuses on product design, technical innovation, product improvement and service innovation, up , to create their own special and personalized products . At the same time , but also to avoid redundant investment and construction , and guide enterprises to gather resources to enhance the original , integrated innovation and re-innovation absorption capacity , extend the industrial chain , on this basis, to expand the scale of production , strengthen national brand building.
Capsule Slip Rings  wind generator slip rings  through bore slip rings  Wind Turbine Slip Rings

Slip ring slip ring is still the main force of low-cost

As the name suggests is used to electrically conductive slip ring slip ring slip ring series in all the most widely used , also known as brushless slip ring , carbon brushes, slip ring, slip ring , slip ring , rotary pass, rotating electrical joints, dedicated to the unlimited continuous rotation , the transmission power of power, signal power .

The choice of the motor brush commutation sparks have an important role in inhibition , should be power, voltage , load characteristics and the selection conditions such as the peripheral speed commutator . Commonly used electric graphite brushes , because resistance coefficient and contact voltage higher, suppression spark favor. But for low-voltage motors , the excessive contact voltage to make it in the proportion of the total voltage drop is too large, so the use of metal graphite brushes .

Since the majority of structural defects brush , so researchers developed a second generation of electricity on the Capsule Slip Rings , slip ring to avoid the kind of brush structure of many shortcomings, such as easy to wear , not oxidation . As modern technology advances, brush slip ring technology has become increasingly sophisticated , just before the use of copper and copper ring brush contacts for signal and current transmission, relatively soft due to copper , rotation speed or when the use of time after a long , easily deformed , affecting close contact , thus resulting in distortion of current and signal transmission . Behind the development of precious metal brushes and copper rings to solve this problem , such as adding trace elements of the alloy conductive materials, rare earth metals, rare metals , etc., a good solution to this problem . Now, brush slip ring slip ring is still the main force of cost . Many large amount of manufacturers, both in the use of cost-effective electrical slip ring , especially equipment price is not high, the number of very large companies , due to cost reasons, brush slip ring is still their first choice.

Optical slip ring selection

fiber optic rotary joint sliding electrical contacts are connected to application areas , it is also known as the collector ring , or rotary joints , rotary electrical interface , slip ring , slip ring , ring back , coils, commutator , adapters, is to achieve two relatively rotating body images , data, and power transmission precision signal transmission devices. Particularly suitable for unrestricted continuous rotation while rotating from a stationary position to the transmitting power or data of the place.

Consisting of elastic material - brushes sliding contact surface material - electrically conductive ring , insulation materials , bonding materials , composite stent , precision bearings , dust and other ancillary parts and other components. Brush adopt noble metal alloy material , was "II" -type conductive ring groove symmetrical double exposure , with the flexibility of the brush pressure and sliding contact conductive ring groove to transmit signals and currents.

Precision slip ring are high-tech products, has long been used in cutting-edge military field , a variety of precision turntable , centrifuges and inertial navigation equipment, key components . As China's economy continues to develop , more and more civilian areas involved in the use of such products for the industrial automation systems control . In advanced countries , these products have been gradually transformed by the military products for civilian products, standardization has been achieved in recent years , mass production , is widely used in security , factory automation, electricity, finance , instrumentation , aerospace , military, transportation , construction and other mechanical and electrical equipment.

Currently used internationally slip ring technology is divided into the following three:

1 , composite brush block technique commonly used carbon brushes, copper brush , silver / graphite / molybdenum disulfide brush block and other forms.

         2 , the use of precious metal alloy filaments , such as AuNi9 so on.

         3 , fiber brush technology , fiber brush is a special kind of sliding electrical contact design . Simply put, fiber brush is to separate the metal filament ( line ) for calibration and put into a metal tube. In this cantilever design, fiber brush bundles in bulk , without shackles attached to one end of the ring road surface trough .

In the industrial market, the rapid development, technical service and maintenance team is also essential, and we choose the collector rings, brushes when we should try to select the excellent quality team , so as to avoid unnecessary trouble. Shenzhen Crystal Electronics Co., Ltd. is a leading Pei , with years of experience focused on the development, production and sales of series of industrial brushes , slip ring, slip ring , conductive ring of high-tech companies . Jing Pei Electronics product line, and various indicators of performance is always at the forefront of similar products , with a number of international authoritative testing organizations that certificate, long-term domestic and foreign well-known manufacturers , military units , research institutes and universities to provide products and technical services, and become a long-term point of qualified suppliers , products are exported to Europe and America, most of the developed countries.

Around the stability and reliability on the slip ring

Slip rings as a crucial element of automation equipment , its stability and reliability and stability in the entire equipment reliability have very sophisticated relationships , it can be said former determines the latter , so the top quality slip ring for sophisticated precision instruments and equipment is crucial. Here's stability and reliability of your slip ring to perform some study instructions.

Slip ring its principal technical indicators have insulation properties, resistance to interference, speak to resistance , and so on. In this paper, these three inquiries on the extensively used in celestial navigation , optical tracking, measuring and optical devices similar to optical search precision slip ring , were analyzed one by 1 .

Insulation

The slip ring is , naturally, the larger the much better insulation properties , no less than , the insulation resistance between the rings and not be higher than the breakdown voltage , otherwise it truly is simple to slip ring reliability trouble. Slip ring consists of a large number of rings, the smaller the distance involving the rings as possible. Could possibly be reality, but depends on the processing in the groove , far more importantly, may be the result of post-guarantee Glue dielectric strength involving the rings . Radial slip ring substantial size plastic irrigation easy, and compact size are problematic Glue , its dielectric strength also depends upon the insulating material filling glue formulations and processes .

Anti-jamming efficiency because the transmission of electrical signals and microwave signal collector rings , immunity to complete improved on the reliability of information transmission much more safe , in reality , slip ring transmission dozens of numerous signals, one can find higher voltage alternating current, high frequency alternating existing, direct current with modest signal weak , a large existing AC , because the distance between the slip ring close to a number of signal in the course of transmission interference with each other , there was the electrostatic induction coupling , magnetic induction coupling and electromagnetic induction coupling . Interference caused by electrostatic induction coupling , etc., all types of interference seriously impact the accuracy with the details transmission . For this reason , superior anti-jamming efficiency slip ring , you need to start off from greater than a few major factors .
Contact resistance

Why should get in touch with resistance as a very critical technical indicator? Considering, if the conductive slip ring sliding contact resistance is also substantial , the current through the get in touch with point when the temperature will rise a great deal, and might possibly even bring about wire brush and slip ring welding , while the contact pressure drop increases , which will influence the facts transmission effect . For that reason, the make contact with resistance is smaller sized the much better way.

So, the elements affecting the size of your speak to resistance are those that do ? Mainly within the following elements: 1 ) the make contact with part with the material
2 ) forms the get in touch with surface plus the speak to when the make contact with stress.
Specifications of the material may be the material very good thermal conductivity, higher melting point, high conductivity, temperature coefficient of resistance is tiny, with anti-curing , anti-oxidation , anti- corrosive gases as well as other qualities with the brush filaments requirements are reasonably higher , you can easily use gold nickel wire but gold nickel wire high-priced. Based on the solution different applications , you'll be able to use brass wire instead.

The above two points , regardless of whether it's for customers of the through bore slip rings , slip rings or the production on the manufacturer , really should be placed in a highly essential position , it may be stated is the most significant , the only way we Jing Pei Electronics slip ring merchandise shall be guaranteed , we've to guard the infrastructure components , we've many different automated machinery and gear protection .

Slip ring of the production process

Before 2002 , the slip ring that domestic or a vague concept, to use slip rings enterprise is bought abroad , in foreign trade on the early rise of the slip ring , and it all into the large-scale production .
