By using the principle is definitely the kinetic energy becomes lookout windmill rotating movement , therefore to promote wind turbines to make electricity. Even though wind power also has its inherent drawbacks , which include intermittent regional.
The so-called intermittent , is within the identical place , couldn't happen to be sustained winds of five , 6 winds. Generally this is the case , as of late the wind especially large, quite a bit of wind energy , more than some days , the wind is very little , resulting in insufficient power . All of us know that electricity is just not quite a bit of stored power due to the fact intermittent wind and bring about alone can not solve each of the difficulties , have applied in conjunction with other power sources , when the wind is little, the input to hydropower, thermal power to become supplemented wind foot when external input energy to other lines. Only within this way are these disadvantages intermittent wind . The so-called regional , on account of geopolitical vast, wind resource distribution is extremely uneven , Northwest Territories and much more, even though the Southeast significantly less, but the Southeast is forced intensive, industrial improvement, demands a lot of electricity provide , as a result , the Northwest Territories wind power requires just after a large number of kilometers through the transmission to have to the south-east , a lengthy transmission distance , the loss is huge, so this shortcoming also restricting wind energy in the southeast area to develop .
wind generator slip rings is applied above a rotary joint elements. So, what exactly is wind energy slip rings do ? Wind energy slip ring is rotating blades of wind energy gear and trunk rotation axis joint parts connecting portion . This component is connected among the fan blades along with the only channel for signal transmission , a whole lot of sensor data should pass through the slip ring wind energy transmission among the joints at one another , but this really is the only 1 that calls for a unique movement of parts, pretty prone to put on and tear . This part is out from the question , the whole typhoon electrical equipment is completely scrapped , so wind energy wind energy equipment slip ring in the status and role is very vital .We can see why now fan gear makers electrical slip rings industrial tender and really strict high quality specifications , that's, for this reason. The slip ring bidding qualifications and needs in a variety of elements of view, wind energy market capacity slip ring is rather massive , the depth can also be a lot more eye-catching, so a great deal of slip ring manufacturer within this regard quite a bit of work and put a whole lot of manpower and material sources to carry out new solution development and design , so as to occupy a spot in the future market place .

On the motor slip ring for industrial development
With the development of science and technology , the motor type and use
more diverse working conditions , and thus require a variety of
different grades of brushes to meet these requirements , it is also the
type of brush as the motor industry development more and more. Capsule Slip Rings
DC motor and the motor can be divided into AC motors , DC motors rotation of the rotor , the need to coil
The position of the magnetic field in a constant and continuous switching current changes direction, so the coil to the DC motor
A commutator . Commutator by the brushes and commutator rings , carbon brush is a brush because of the rotor
( Centrifuge rotor) for rotation of the brush is always rubbing the commutator ring , and also at the moment of commutation
Spark ignition eclipse , so brush DC motor is in the wearing parts in order to improve the DC motor
Service life , operating stability and reducing noise of the DC motor and electromagnetic interference , brushless DC motor
Have gradually replaced the brush motor trend. General AC motors do not constant magnetic field , so no need to commutator
, There is no need to brush .
Collector ring is used for motor commutator or slip ring , as export and import current sliding contact body , its electrical conductivity , thermal conductivity and good lubricating properties , and has a certain mechanical strength and commutation sparks instinct. Almost all motors use brushes , which are important components of the motor . Widely used in a variety of AC and DC generators, synchronous motor , battery DC motor, crane motor slip ring, various types of welding machine and so on.
Then we use slip ring assembly in the process should pay attention to what the problem?

domestic market slip ring in the new energy development and utilization of the opportunities backdrop
In the new energy development and utilization of intensified today,Wind Turbine Slip Rings
supporting the production of each new energy enterprises and factories
are gearing up in the next big industry in place , due to poor channel
new energy , wind power, hydro , photovoltaic and other user market and
faced less electricity load and other factors , which restricts the
development of renewable energy , together with the majority of new
energy is unstable energy sources such as solar energy, low energy
density per unit area , there is diurnal variation , wind as well. Slip
ring manufacturer earthquake in Japan is very concerned about this , why
?
Here we take a closer detail said that the recent earthquake in Japan caused by the nuclear incident caused a lot of controversy about the new energy , the two most important is the focus on the development of new energy future direction of the problem is the wind, solar or nuclear energy do ? Either way , the future industrial layout, and industry chain development has played a very significant impact around from electricity generation costs, the average price of coal-fired power Xinjiang 0.235 yuan per kWh , while the cost of wind power about 0.5 yuan per kilowatt , renewable energy with coal, oil , natural gas and other traditional energy sources , regardless of the total cost of investment in fixed assets , or , do not have the business competitiveness .
So for early access to these information patterns of development and direction , for a slip ring manufacturer is very important, this is achieved in the next competition opportunities and the initiative is a key link . Let's deny solar energy, we all know that solar energy though is a clean energy, new energy , but also a direction of development, but for inputs and outputs as well as future large scale applications , there are many issues remain unresolved , such as said environmental pollution problems, solar energy itself no pollution problem, but to absorb energy in the production process of the polysilicon , is a very energy-intensive and polluting material . Because a large amount , a lot of manufacturers in order to catch the goods or ignore environmental problems often lead to new energy , environmental protection and energy issues are not environmentally friendly , this one, is really only an expert can understand the secret, because the slip ring manufacturer that Ka Chi in the future as the new large-scale application of solar energy application possibilities can be ruled out .
Finally, wind energy, wind energy is the only large-scale application and promotion of a new energy, new energy , experts in the case of Ka Chi think so. First wind energy is a clean energy , which is also in the production of manufacturing equipment without any contamination , significant increase in sales of wind power slip rings can be seen on a recognition of the market for wind energy , a lot of places in the country , wind energy resources are very rich , As China's vast land , air very much, and in the northwest region , many places are very suitable for large-scale application of wind energy, wind power equipment in the slip ring occupies a very high percentage , wind energy potential for slip ring manufacturer is very important.
Chia Chi Electrical is the leading wind generator slip rings manufacturer , has a very strong technical strength as well as research and development capabilities , capable of producing high-end high- speed slip rings, wind slip ring applications and new product launches favorable driven wind power equipment upgrades, improve the efficiency of wind power generation , and promote the process of large-scale application of wind energy .
At this stage the price of renewable energy than conventional power generation is high, without government support , the development does not go . United States, Britain , Japan, Austria, Australia, Sweden and other countries to support renewable energy generation , in general there are quotas , compulsory purchase , price subsidies , government procurement, fiscal incentives , green pricing and other methods. As for nuclear power , for Japan, the former Soviet Union two painful lessons of the incident , had to remind us that nuclear power is a very terrible thing, in humans have not fully understand and control before him , Kerry 's proposal is to minimize Chi utilization levels can experiment , but the consequences of large-scale applications can imagine , if there is a mishap , nuclear energy is not controllable , and the consequences will be global catastrophe , even human big problem. Nuclear power in many areas have a certain application , but are on the cutting edge , a few areas of application, but not large-scale application . windmill slip rings manufacturer application prospects for nuclear power are not very optimistic.

Slip ring brushes and the oxide film
According to statistics, three relay pump operation has been burned eight switches. Collector ring temperature: brushless slip ring oxide film generally easier to form at about 70 ℃, when the collector rings, brushes overheating failure, usually at temperatures above 150 ℃, then even if the new ones brush, the oxide film is not easy to form, can not play the role of lubrication, brush wear will increase, resulting in the temperature continues to rise, become a vicious cycle. slip rings then you can take the external forcing cooling methods, such as Vaseline, high-power fan ventilation and other means, so that the collector loop temperature falls within the normal range for some time, so that the brush surface oxide film formed gradually make it into the virtuous circle. In addition, the rotor via a resistor, you can also speed. Compared with squirrel-cage motor, the motor is characterized by its complex structure, high cost, convenient operation and maintenance, maintenance workload. Collector ring pump relay switch model DW15-C630 type, wind slip ring rated current of 630A instantaneous stop 6300A, switching arc chute mutually insulated copper steel composition, arc performance is poor, relay pump the start and stop time will be in high temperature electric arc generated between the switch contacts, frequent start-term high-temperature heat generated by the arc degree of oxidation of the contacts increase, the contact resistance between the contacts increases, the main contacts of the switch firing sticky, damaged, or even cause the switch to an explosion, causing expansion of the accident.
