Description

ALLOWS:

- to support dynamic efficiency of electroreceivers in the range of nominal, providing reduction of consumption of active power, as a rule, from 5 to 25 depending on operating modes, and in some cases to 80;


2. PRINCIPLE OF WORK

The principle of a resonance of current is the basis for the principle of work of RPE. The mode of a resonance of currents has great practical value. At a resonance of currents of their fluctuation occur in an oscillatory contour, the external source only fills up losses of energy on active resistance. In electric chains partially there is an exchange of energy between generators and consumers that loads a network and increases losses of energy by its transportation (for example in transformers, wires, etc.). To relieve a network of these losses, on the place of the receiver, by means of RPE, the current resonance is created. The resonance of current increases loading power factor (a cosine fi) to 1. Increase of a cosine fi to 1 electrical units is very important economic task as this increase designates economy of a huge number of the electric power lost in networks and the equipment at a low cosine fi and improves use of huge capacities of generators of power plants.

6. CONNECTION AND OPERATION OF THE DEVICE

RPE is connected parallel to the consumer (the engine, the compressor, etc.). After connection turning on of the resonator is made by the start-up key.

The resonator is operated in an operating mode of the consumer of current.
