The analysis of modern hardware on ensuring electromagnetic compatibility of systems on industrial facilities |
O.V. KRYUKOV
The analysis of the causes and features of impact of hindrance on the modern electronic equipment of control systems, monitoring and
diagnostics of technological installations on industrial facilities of the increased danger is submitted. On characteristic examples of objects
of PJSC Gazprom need of creation of effective protection against direct stoke of a lightning and secondary manifestations according to
normative and technical design methods of system of external lightning protection is shown. On the basis of the method of the rolled
sphere used in the international standards object-oriented methodological and technical solutions on lightning protection of the antennas
installed in a zone of direct stroke of a lightning are developed. The developed systems of lightning protection of antennas have undergone
successful introductions on various objects, and interaction with domestic manufacturers of antenna support has allowed to develop the
unified designs of systems of lightning protection for different types of antennas. It is shown that in case of the high resistance of contours
characteristic of eternally frozen, rocky or sandy soil, the meters of the grounding devices normalized couple are exigeant, motivating
installation of the chemical electrodes which are specially developed for soil with high specific resistance.
Keywords: control systems, hindrance, antenna, electromagnetic compatibility, lightning protection, grounding device.
