Tepelné ochrany

Tepelná ochrana proti přetížení (nadproudu)Nejběžnější poruchou ve vinutí motoru je jeho nadměrné oteplení. Teplota roste vlivem proudového přetížení vinutí. Charakteristika na obr. 1 znázorňuje, jak 5% nárůst proudu odpovídající zvýšení teploty o 10 °C zkracuje životnost vinutí na polovinu.Ochrana proti přetížení je tedy nezbytná pro zamezení nadměrného oteplení a snížení rizika selhání motoru v důsledku poškození izolace vinutí.Princip činnosti tepelných nadproudových spouští je založen na deformaci bimetalového pásku, kterým prochází sledovaný proud. Při průchodu proudu tímto páskem je pásek deformován, přičemž v závislosti na nastavení jsou rozpojeny kontakty.Spoušť lze znovu nastavit (resetovat) po dostatečném ochlazení bimetalového pásku.Tyto spouště reagují i na ztrátu fáze: diferenciální princip. Zmíněná funkce brání jednofázovému chodu motoru a odpovídá požadavkům norem IEC 60947-4-1 a 60947-6-2.
