Asynchronous current generators will help you at blackout with country house or when building buildings in the areas which are not equipped with current networks. Such generator is, of course, electric engine, but it is set in motion not by the electric power, but alternative energy sources.
Asynchronous generators are alternative sources of electrical energy. As the drive for rotation of the rotor of the asynchronous generator serves the internal combustion engine which usually uses gasoline, or the diesel which uses diesel fuel.
Generator device
This generator consists of two parts, one of which is motionless both the stator is called and is the basis. Mobile part is called the rotor, it rotates in the stator.
The stator and the rotor make of special electrotechnical steel which carries very well out the magnetic fluxes which are formed during their work. Asynchronous generators can be both three-phase, and single-phase. It depends on quantity and type of connection of windings in the stator and the rotor. Conducting part of rotors is carried out aluminum and electrotechnical steel. At the beginning of rotation of the generator the internal combustion engine located on one platform together with the generator the running magnetic field which it will be transformed to electric current subsequently is formed.
Principle of work
Frequency and power of the received electric current on straight line depend on generator rotational speed. The generator rotational speed is higher, the power and tension are more if speed falls, then also characteristics of electric current go down. Therefore on many generators the automatic control of these parameters that they have not affected quality of the given energy is established. It is possible to carry the fact that they are consumers of reactive power to shortcomings of asynchronous generators, and owing to overload at start in stator winding considerable currents which can lead to winding exit out of operation will proceed. For elimination of this defect of design condensers are used.
Application
Asynchronous generators are recommended to be used if high requirements are not applied to parameters of tension, the generator works in bad surrounding situation (for example, the increased dust content), not perhaps qualitatively to serve the generator at operation and also if there is possibility of overloads and emergency operation of work.
Safety measures
In spite of the fact that the generator easily gives power in 380 Volts, do not use it without extreme need. Tension, safe for operation of the generator, – 220 Volts. Take care of grounding, protect the device from children and animals. Do not drive the generator idling.
