Machinery & Energetics

The methods and apparatus for the resonant system of electric power transmission for stationary consumers and mobile electric transport are considered. Substantiation of wireless electric power transmission using on electroconductive channels created by electron beams, laser and microwave radiation is given. It has been experimentally confirmed that in a singlewire high-frequency line there is a phase shift of 90° between standing waves of current and voltage. The current is reactive and capacitive in nature. There is no active current or direct current in the line. The frequency converters have an automatic tuning of the frequency to the resonance frequency in the line. The problem of electromagnetic emission from singe-wire cable is solved by the fact that the cable is shielded and the screen consists of separate isolated sections; the length of each section of the screen is much smaller than the wavelength corresponding to the resonant frequency of electrical energy transmission. There is no loss of corona in an insulated screened cable. For electromobiles, non-contact (non-trolley) transmission of electrical energy is used at a distance of 0.1–0.35 m from a single-wire line to an electric vehicle. The implementation of electrotechnics, carried out on the basis of the resonance method for different electrotechnology facilities is presented. The description of experimental samples of resonant cold-plasma coagulator is given. The results investigations of experimental samples of the resonant electric power transmission system are discussed.
