Analysis: How some cities the use of wind

Wind power as a large-scale application of clean energy now , the country has begun to vigorously popularity due to the support of national policy and local government support, the development of wind power industry is very fast , we have said earlier , the use of wind energy for power generation, clean energy is one of the most , since the construction of large-scale wind farm requires a lot of capital investment as well as a very empty area and wind resource  Wind Turbine Slip Rings-rich areas , such conditions in some cities almost achieved , then how to use some cities wind it ?
Sometimes, we drove on the road to go, if we all stay in mind , you will find a lot of the city's street , above a small windmill , some people would certainly think that it is an ornament , is the city's landscape embellishment , it is large mistake for , this is the big city using wind energy equipment. More common , especially coastal cities , such as Hainan , Shenzhen, Zhuhai , who constitute a small windmill city a beautiful landscape , very beautiful, especially the coastal high-speed, blue sea , lush green belt , with white windmills in turning from time to time , like a landscape painting. However, it is not just a landscape, but also one example of the use of renewable energy sources .
When we carefully explore those lights, strange without wires , we do not wonder, you're right , because it is entirely on the wind to light , and small windmills in the daytime when there is wind , the generated electric power is stored, although electricity can not be mass storage, but small-scale storage or a big problem . Night, the power to release those who take advantage of nature , no pollution , no noise , is the perfect source of energy.
For small wind generator slip rings power equipment , the most important is the wind power storage and transmission , as well as small-scale wind power equipment prices and costs , to solve these two problems , small wind power equipment marketing is much simpler , and those traffic lights at the small wind power equipment, 24 hours a day in the rotation , what guarantees can not fault the unceasing rotation ? That is wind power slip rings .Small wind electric slip rings are on the master device and the blade rotation sensor Unicom joint parts together to ensure that the master device always detect temperature, humidity , wind speed and wind direction sensor data , and transmitted to the master device for processing, and to make consequential adjustments and movements. Wind power slip ring is the main bridge between the device and the blade is an integral fan , the fan is crucial to the stability of components.Cities using wind now still in an early stage of exploration, when our family air-conditioning , electric wires do not need it , that is the golden age of wind power generation equipment , we want to see in the future scenic , living area, everywhere clean Energy has a shadow , the presence of windmill slip rings power everywhere .

Slip ring brushes are used for winding induction machine

Brush slip ring are used for winding induction machine, moving and stationary electrical connection device, the biggest problem is caused by the high failure rate cantilever structure maintenance volume. This is the traditional 200-year legacy of motor learning difficult problems. Wound conventional slip ring induction machine is "airborne" slip rings, the slip ring device is mounted on the rotor shaft end of the motor, slip ring is actually a single-ended cantilever support structure, so the motor during operation, since centrifugal force and radial unbalanced moment role will inevitably slip ring a radial jitter, particularly during startup and running speed, the phenomenon is more obvious. From material procurement, technology, manufacturing, inspection, test, package until delivery, improve the working procedures and management standards, the entire process of production in a controlled state. Jing Pei Electronics wind energy equipment companies in a an installed capacity of 500,000 kilowatts in order to ensure no loss, and our country's total installed capacity of one year only 10 million kilowatts. 2009 Global separate slip rings add 31%, a total increase of 37,500 MW of new capacity, the world's total installed capacity of 157,900 megawatts of new heights. Chinese high-current slip rings and broad development prospects, anticipated future long period of time will maintain rapid development, while profitability will increase as the technology matures steadily. Airborne system configuration of slip rings, brushes, there are structural difficulties in the heat, in general, slip ring surface temperature more over 8 0 CC, increased wear and tear, the slip ring brushes reliability is further reduced. At the same time, produce a lot of carbon brush wear, scattered in the insulation between each phase slip ring, slip ring very prone to phase short circuit and cause grounding, slip ring system will be completely damaged.

How to cooperate to use collector ring and motor

Collector ring has many names, such as conductive ring, slip ring or ring, collecting ring result there are many ways, there are die-casting and slip ring assembly, materials are not the same, there was also of steel copper. First, the original mounted on the motor shaft of the slip ring, the brush device is designed as an independent set of electrical device, via electrical cable tray flange and the motor are mechanically and electrically connected. New slip ring slip ring brush device with double bearing support, electrical slip ring power flange plus cushioning effect, collecting ring jitter can be completely avoided; Meanwhile, the motor shaft is no longer in direct contact, new slip ring collector ring brush device small diameter, which is about half the diameter of conventional slip ring, slip ring speed reduced by 1/2, the corresponding brush wear significantly reduced, life can be increased by 3 - 4 times . Replace the motor,fiber optic rotary joint when installed in place, so that collector ring contact area with the motor shaft assembly to reduce or too loose and cause the vibration will cause problems. Conductive ring before assembly should first check the size selection with the use of basic shaft system. Avoid improper selection tolerances appear too tight or too loose phenomenon. Collector ring operating state without exception jitter, which can solve the fundamental problem of conventional ignition. New collector ring wire-speed low-life, traditional products can be about 6 times. Collector ring in the new overall configuration of the brush contain automatic test features to improve efficiency.
