Abstract

In the work is examined the mathematical models and experimental results of the electromagnetic field allocation around of a source as inductor. Value of the effective magnetic permeability is defined as the left side of the corresponding non-linear equation a relatively unknown average value of magnetic field strength fluctuations during the period in the core. By increasing the length of the core above the critical value will not occur a further increase in the intensity of the radiation of the inductor - core is already intercepts the overwhelming part of the energy component of the magnetic field inside the coil. Tool measurements and the computer values of the electromagnetic field parameters have confirmed adequacy of the offered models. The effective relative magnetic permeability increased on increase in ratio of the core diameter to the diameter of the coil k1 (duty ratio) and the ratio of the core length to diameter k2 at sufficiently large values of the duty ratio. With a duty, cycle of less than 0.2 k1 dependence of the effective relative magnetic permeability of the coefficient k2 is extreme. The electromagnetic fields effect on the man in the technological processes consisting of several one-type sources is examined. Device of high-frequency heating is set of generator, the feeder line and the inductor. To date the industrialized mastered the production of high-frequency generators, not manned technological rigging (including inductors), which define the structure of the electromagnetic field in the surrounding space. The tools of individual protection of serving staff are offered. The protective costumes, aprons are made on an electro conducting strings basis. Proposed means of an individual defense against electromagnetic radiation: protective suits, aprons, made from fabrics (ÒÝÍ-08ÒÝÍ -09) on the basis of conductive filaments with mandatory implementation of the grounding. The peak efficiency of shielding was observed at grounding resistance up to one kOm.
