Description

DESCRIPTION

The utility model relates to electric generators generating three-phase electric current. Existing low-power generators, up to 15 kW based on asynchronous | electric motors are used to rotate their rotor, when converting mechanical energy into electric current, turbine fins. The Chuvashia Energosapchast Plant produced micro hydroelectric power stations with a capacity of 1.5 kW and in Crimea near Balaklava, an acllIixon electric generator of 125 kW was used, the rotor of which rotated from a wind electric installation (SM. 2 3 magazine for ISS5 g). The essence of the utility model. Consists in the replacement of dvukhchetel (turbine or wind. Electric installation) ro4

Then, when the turn of the generator rotates, an electric current will be generated, the quality of the electric current is monitored using devices located on the electric panel (7), an ammeter (RA), a voltmeter (P) and a control lamp (E). To rotate the rotor of the generator (Gj) requires a three-phase electric motor (G), providing | rotation of the rotor of the generator (Gl) with a frequency that makes this rotation more than the passport data of the asynchronous generator (Gj) by 10. For example, an asynchronous electric generator (yor (Gj) gives the rotation of its rotor rpm in the passport. In this case, its rotation rotor needs to be increased; increase to IIOO rpm, then the generator will be excited ..

similar features in their electrical circuit with existing electric generators operating from turbines or an electric wind turbine. The inclusion of stator windings on the Star, but differ in the mechanical part. Started electric generator (I) by starter (4) through spur gears (3) see fig. It feeds electric motor () cm, electrical circuit. Mechanically connected with an electric generator () and a belt drive (9), the electric motor rotates the rotor of the electric generator (I), which generates an electric current, cm, electrical circuit. In this case, the electric motor replaces a turbine or a wind electric installation.

To start the electric generator (Gj), it is necessary to include in its stator (1,2,3) charged and selected according to the table capacitors (Cj, Gr ,, Gg) with the switch () and turn its rotor with a starter until the electric current appears on the control devices ( RA). Apermeter (PV) voltmeter, see wiring diagram, see fig.

Since asynchronous electric generators have a small starting torque (poorly taken off), the electric motor (G) on the wiring diagram, and (2) in Fig., Connected to it electrically to a star and mechanically through a wedge-shaped belt drive (9), it is desirable to untwist with a starter ( 4) and already after that switch on ((2 /; 2, ®) work with the electric generator.

To stop the generator (G-j), it is enough to disconnect the charged capacitor (Cx, Cr, Co) from its stator windings (1,2,3) and the output
