Abstract:V industriji se zelo pogosto uporabljajo električni stroji in naprave, med katere sodijo tudi asinhronski elektromotorji. Težava nastane takrat, kadar se asinhronske elektromotorje potrebuje na tako imenovanih eksplozijsko nevarnih področjih. To so področja, kjer so prisotne koncentracije vnetljivih plinov ali tekočin in bi posledično lahko ob prisotnosti iskre, električnega toka ali visoke temperature prišlo do eksplozije. Ker ta področja industrije ne morejo obratovati brez asinhronskih elektromotorjev, se je v ta namen razvil poseben tip oziroma izvedba. Takšna izvedba se imenuje eksplozijsko varna, in ima lastnost, da tudi če bi zaradi katerega izmed zgoraj navedenih razlogov prišlo do eksplozije, se le-ta ne bi razširila v okolico. Ker je v današnjih časih potreba po eksplozijsko varnih asinhronskih elektromotorjih vse večja, je celotno diplomsko delo orientirano k njim. Natančneje cilj diplomskega dela je merjenje karakteristik eksplozijsko varnega asinhronskega elektromotorja, s poudarkom na merjenju izkoristka za razred IE3. Pri tem so bile opravljene meritve na prototipnem eksplozijsko varnem asinhronskem elektromotorju, v dveh različnih merilnicah. Predhodno je bil opravljen še analitični izračun z zato namenjeno programsko opremo. Povsem na koncu diplomskega dela pa je sledila še natančna analiza rezultatov, v smislu neposredne primerjave rezultatov iz obeh merilnic, z rezultati, dobljenimi s pomočjo analitičnega izračuna.

Title:Measurement of characteristics of an explosion-proof protected induction electric motor
Abstract:Electric machines and devices are very often used in industry, including induction electric motors. Problems arise when induction electric motors are needed in so-called potentially explosive areas. These are areas where concentrations of flammable gases or liquids are present. As a result, an explosion could occur in the presence of a spark, electric current, or high temperature. Since these areas of industry cannot operate without induction motors, a special type or design has been developed for this purpose. Such design is called explosion-proof, and it has the property that even if an explosion were to occur for any of the reasons above, it would not spread to the surroundings. Since, nowadays, the need for explosion-proof induction electric motors is increasing, this thesis is oriented toward them. More specifically, the aim of this thesis is to measure the characteristics of an explosion-proof induction electric motor, with an emphasis on measuring the efficiency for class IE3. In two measuring laboratories, measurements were made on a prototype explosion-proof induction motor. Beforehand, an analytical calculation was performed using dedicated software. At the end of this thesis, a detailed analysis of the results followed, in other words, a direct comparison of the results from both measuring laboratories with the results obtained with the help of analytical calculations.
Keywords:induction motor, explosion-proof, performance tests, analytical calculation
