Optimizacija izbire termične varovalke na podlagi merjenja temperature

GOVEK, MIHA (author), Bojkovski, Jovan (mentor)

Cilj diplomskega dela je optimizacija izbire termične varovalke z avtomatičnim ponovnim vklopom na pogonu kuhinjskega aparata. Obstoječa termična varovalka se nahaja na elektroniki in je ločena od izvora toplote (statorsko navitje). Izboljšava je namestitev termične varovalke na izvor toplote, to je na površino statorskega navitja oziroma na tuljavnik, neposredno nad navitjem statorja. Naloga zahteva posnetek obstoječega stanja ter izmeritev referenčne temperaturne krivulje, ki bodo osnova za izbiro ustrezne termične varovalke. Na podlagi vzorcev termičnih varovalk z avtomatičnim ponovnim vklopom proizvajalca Sensata in meritev smo se odločili za termično varovalko, ki ščiti motor, komponente in celoten aparat pred toplotnimi poškodbami v primeru nenormalne uporabe.

• Title: Optimization of a Selection of a Thermal Fuse Based on a Temperature Measurement

Abstract

The goal of the thesis is optimization of choice thermal cut off on the kitchen appliance drive. Existing thermal cut off is located on electronics and it's separated from the source of heat (stator winding). The improvement is the installation of thermal cut off on the heat source, that is on the surface of coil holder or inductor directly above the stator winding. The task requires a recording of the current state and measurments of reference temperature curves, which become a basis for choosing the optimal thermal cut off. Based on samples of Sensata manufacturer and our measurements , we decided for a thermal cut off that protects the appliance, its components and the complete device from thermal damage in a case of abnormal usage.
