Eksplozijska zaščita v avtomatizaciji

KOŠMERL, JAN (author), Karer, Gorazd (mentor)

V magistrskem delu so predstavljena strokovna področja, ki jih mora poznati projektant električnih inštalacij, pri izdelavi vezalnih shem avtomatizacije tehnologije za PZI (projekt za izvedbo) industrijskega objekta, za katerega je predvidena eksplozijska ogroženost. Tako je predstavljeno splošno področje avtomatizacije s strani elektrotehnike, ki zajema sestavne dele CNS, s poudarkom na lastnostih krmilnikov in enot RIO, ki so pomembne pri izbiri opreme uporabljene za projektiranje. Prav tako je v magistrskem delu poudarek na delu CNS, ki zajema periferne enote, in sicer predvsem na razumevanju tehnoloških shem, ki jih izdela projektant tehnoloških procesov, ki izbere tudi ustrezno periferno opremo. Sposobnost branja tehnološke sheme procesa je za projektanta električnih inštalacij ključnega pomena, saj so na njej označeni vsi signali, za katere mora predvideti povezavo s krmilnikom ali enoto RIO. V delu je predstavljena tudi direktiva ATEX, ki jo mora projektant električnih inštalacij upoštevati pri izbiri opreme, za katero je zahtevana vgradnja in delovanje v eksplozijsko ogroženem okolju. Predstavljen je tudi primer tehnološke rešitve avtomatizacije realnega objekta. Pri tem so predstavljeni krmilniki in enote RIO, uporabljeni pri izvedbi avtomatizacije. Vključena je tudi analiza enot RIO, primernih za vgradnjo in delovanje v eksplozijsko ogroženem okolju, ki je pripomogla k izbiri najprimernejšega sistema.

Abstract

This master’s thesis presents technical areas, that must be known by the designer of electrical installations, who is responsible for the preparation of circuit diagrams for the automation of technological equipment for projects with a possible risk of explosion. Thus, the general field of automation considered by electrical engineering is presented, which consists of a building automation system. The characteristics of controllers and RIO units are highlighted, which are important for the selection of devices used for designing diagrams. This thesis also focuses on the part of building automation which includes peripheral devices, but mainly with the aim of understanding the P&ID diagrams of technological processes which are crucial for the designer of electrical installations, since they indicate all the signals for which a connection to the controller or RIO unit must be provided. The work also presents the ATEX directive, which the designer of electrical installations must take into account when selecting equipment required for installation and operation in a potentially explosive environment. An example of an automation solution of a specific project is also presented, as are the controllers and RIO units used in the implementation of the automation. An analysis of the RIO units, which are suitable for installation and operation in a potentially explosive environment is also presented, which helped in the selection of the most suitable system.
