| dc.description | The treatment of wastewater and industrial effluents
by electron beam irradiation is a promising technique, however, not
very widespread in Brazilian territory. The design and construction of
a mobile unit by the Nuclear and Energy Research Institute,
containing an electron beam accelerator of 700 keV and 20 kW is
innovative to demonstrate the effects and positive results of this
technology. The aim is to transfer the mobile unit to several
companies with interest in liquid waste treatment, connect to the
industry electrical system and start the ionization treatment process
through electron beam. The mobile unit connection to the local
electrical system may be a challenge due to the great diversity of
voltages and distances involved, as well as the large injections of
harmonic content generated by the electron beam accelerator that can
affect sensitive loads in the industrial system. In this work, an
analysis of the electrical power system of the mobile unit was made,
regarding the interruption capacity, selectivity protection and
adequate short circuit levels, in order to assure a greater reliability in
the operation. At the end, the control panel of the mobile unit,
simulations and measurements were carried out at the 1.5 MeV and
37.5 kW electron beam accelerator, installed in the Radiation
Technology Center, demonstrating the necessity of applying a filter
to reduce the measured harmonic distortion. The analysis of the
mobile unit electrical power system was made, in order to assure a
greater reliability in the operation. | |
