Generator which is used as decoration

July 9th, 2010 aboutgenerator No comments

Preface: scientist has produced soft power rubber, when fold it, it can transform eighty percent of mechanical energy into electrical power. We can use this kind of material to make shoes, clothing accessories, and daily used stuff, even we can implant it into body as power.

“This looks like a pair of shoes, actually it is a charger”, if we remake the movie nation-produced 007, maybe we will have this sentence in the movie, the shoes which is transformed into a fan in the movie has been out of date.

Now scientist has manufactured a kind of tiny generator which we can put it in the coat, fix it under the shoe pad, maybe years later, it is not that funny when we pull a piece of wire out of shoes and use it for charging mobile phone, nowadays with the development of micro technology and material, people can charge for device at any time.

At the early of 2008, professor Wang from Georgia university of science and technology makes a kind of material which can produce power, at the best case, this material can produce 80 MW at every square, under the microscope, we can see every group of electric material’s structure likes two curve cones, when the material is folded and shook, two cones are compressed together and produce electricity.

The theory for this generator is piezoelectric effect, just like lighter. In 1880s, curie and his brother found some crystal can transform between mechanical energy and electric energy. Now in our daily life, there is large amount of piezoelectric material, from quartz to small component in watch, from aerospace to deep ocean.

Piezoelectric material has a big family, they have the common aspect which is that the centre of electric charge is not always at the same position inside lattice, although it appears that it is neutral, but the micro deformation of shape can change the distribution of electric charge, and in macro aspect, it turns out to be current.

According to the assumption of Macarl, those devices which can product electricity with micro deformation can produce electricity through the deformation of lung when somebody is breathing, and they can supply power for pacemakers.

Now the researchers hasn’t tested the biological safety of this generator on animals yet, if it can charge for mobile phone or iPod, it can be counted as valuable products. With more and more low energy-consumption in electric device, we are becoming more and more reliable to portable equipment, this kind of soft generator can bring us more and more freedom in using portable equipment.generator-which-is-used-as-decoration

ABB promote new wind generator

July 9th, 2010 aboutgenerator No comments

abb-promote-new-wind-generatorABB will promote new series of wind generator with slip ring, this new product increases its performance through reinforcing the structure of rotor and modular design, and it will show up at 2010 Asia wind energy meeting which will be held in Beijing during the end of June.

In June of 2010, ABB enterprise which leads the electric and automatic technology areas in the world promotes new series of generator with slip ring in it, through introducing global double-feedback concept, the research of new style generator is based on method which is used by the main turbine machine producer since 1997, and the method is reliable and have high efficiency which is used all over the world.

The new style generator’s power range is between 1.5 and 2 MW, through using modular design, the device has strong match, and can be used at different kinds of double-feedback turbine generators which are currently popular, so it is perfect choice for the update of devices in wind turbine generator group. The production base can product generators with power, at the same time, ensure the quality and quantity, and the connection interface which is used to connect different turbine generators can be determined according to the demand of customers. We offer customers air cooling method and water cooling method, specially produce generators which the frequency is 60Hz for American market.

The design of New style generator’s rotor has acquired patent in America, the bottom of winding has the optimized supporting ring, which can bear high speed working condition, and can cool the device better and fast.

ABB enterprise is the reliable supporter of wind generator, has a good reputation, and is famous for producing generator, converter, all kinds of electric components in wind generating system. In the past thirty years, ABB enterprise has produced approximate 30000 wind generators. The advantage of this new wind generator is based on the experience of 100 years’ effort on manufacturing better generator.

This new generator will show up at this June in Beijing, at the same time, it will be sold to all over world in shanghai ABB enterprise.

The introduction of silent diesel oil generator group

July 8th, 2010 aboutgenerator No comments

the-introduction-of-silent-diesel-oil-generator-groupDiesel oil generator and low noise diesel oil generator meet the national criteria GB2820-90 and some relative national criteria, and are widely used in post station, hotel, entertainment place, hospital, high-rise building which have strict request for low noise.

Low diesel oil generator group is composed of low noise work station, low noise automatic generator group, low noise bus station, low noise electricity station and so on. Low noise diesel generator has stable performance, reliable working condition, low emission, low diesel oil consumption and so on.

Here is the feature of low noise generator. 1, significant low noise performance, the up level of the noise value of generator group is 75 dB. 2, the structure of generator group is tight, have little occupation of  space, and the good looking appearance. 3, multi-layer shield prevent the noise from entering. 4, it has many channels which can compress air in or out to make noise reduce significantly. 5, combustion chamber can hold large volume of oil. 6, we can open the cover plate swiftly and quickly, and have easy maintenance.

 The feature of low noise generator group is listed as follow, when we keep a distance of one meter from the generator group, noise value can be reduced to 80 dB or less than 80 Db, the adjustment of steady-state voltage is between -5% and +5%, the adjustment of transient voltage is less than 20%, the adjustment of steady frequency is less than 5%, the  adjustment of transient frequency is between -10% and +10%, the adjustment of no-load voltage is more than 95%Un.

The parameter of technology of low noise generator group is listed as follow, the rated voltage is 400V, the rated turning speed is 1500r/min, the rated power is 50Hz.
