ELECTRICAL SOLUTION OF THE DIELECTRIC AND ITS INFLUENCE ON FLAME EMISSION WITH ELECTROMAGNETIC FIELD

Studies have been carried out on the effect of an electric breakdown of a dielectric on flame suppression by an electric field of high voltage. In the course of research in the event of electric breakdown of air, the quenching efficiency was reduced to zero. This effect occurs due to the drop in electrical tension between the electrodes. The electrical breakdown in dielectrics when extinguishing a flame is due to the presence of a certain number of ions and electrons, which under the action of the electric field move to the anode. It is established that the electrical strength of the material exerts the greatest influence on the outcome of experimental studies on extinguishing a fire by an electromagnetic field. Therefore, increasing the values of the electrical strength of the material (dielectric), it is possible to exclude the possibility of electrical breakdown. If glass and electrotechnical porcelain are used as dielectrics on electrodes, the boundaries of the investigation flame process by an electric field of high tension will expand. Studies have shown that an electric breakdown has a negative effect on flame suppression by an electric field of high tension. The probability of electrical breakdown is influenced by such parameters as: the distance between the electrodes (the probability of breakdown increases with decreasing distance), atmospheric pressure, air humidity (the probability of electric breakdown decreases with decreasing air humidity), the strength of the material (with an increase in the strength of the material, the probability of breakdown decreases ) and voltage at the electrodes (with increasing voltage, the probability of breakdown increases). In the course of the research it was established that an increase in the electrical strength of the electrodes will allow to conduct studies with a voltage of up to 20,000 kV without the occurrence of electrical breakdown.
