, Funkcia zariadenia spočívá v tom, že skúšané tepelné poistky 7 obsluha zasúva po jednom kuse dó elektrických zásuviek 5 venca 4 karuselu 3, vo vkladacom priestore 39 zariadenia. Otáčajúci sa karusel 3 unáša jednotlivé skúšané tepelné poistky 7, ktorých snímače 18 prechádzajú oblúkovým! kanálom 17 prvého oblúkového segmentu 16, tepelne riadeného na spodnú skúšobnú teplotu, pri! ktorej ešte tepelná poistka 7 nesmie vypnúť. V případe, že vypne, je vyhodená do sklzového žlabu 26 ako chybná. Ďalšie skúšané tepelné ‘ poistky 7 prechádzajú do oblúkového kartálu 17' druhého oblúkového Segmentu 16, takisto tepelne , riadeného, avšak na homú skúšobnú teplotu, pri ktorej musia vypnúť. V opačnom případe je tepelná poistka 7 vyhodená do druhého sklzového žlabu 27 ako chybná. Všetky ostatně skúšané tepelné poistky 7 sú vyhadzované ako dobré do tretieho sklzového žlabu 31. Vyhadzovade ústrojenstvo 32 pracuje tak, že elektromagnety 28 pre prvý sklzový žlab 26 a druhý sklzový žlab 27, ktorými prechádzajú chybné výrobky sú v činnosti iba v případe zistenia chybného kusu, zatial čo elektromagnet 28 pře třetí sklzový žlab 31 je v činnosti pri každom pootočení karuselu 3 o jeden uhlový rozstup 19,The function of the device is that the tested thermal fuses 7 are inserted one by one by the operator into the electrical sockets 5 of the rim 4 of the carousel 3, in the insertion space 39 of the device. The rotating carousel 3 carries the individual tested thermal fuses 7, whose sensors 18 pass through the arc. channel 17 of the first arc segment 16, thermally controlled to the lower test temperature, at 100 ° C; which the thermal fuse 7 must not switch off. If it shuts down, it is ejected into the chute 26 as faulty. Further tested thermal fuses 7 pass into the arc cartel 17 'of the second arc segment 16, also thermally controlled, but at the upper test temperature at which they must be switched off. Otherwise, the thermal fuse 7 is ejected into the second chute 27 as defective. All the other tested thermal fuses 7 are discarded as good in the third chute 31. In particular, the device 32 operates such that the electromagnets 28 for the first chute 26 and the second chute 27, through which the defective products pass, operate only when a defective piece is detected. whereas the electromagnet 28 over the third chute 31 is operative at each rotation of the carousel 3 by one angle spacing 19,
