Abstract
"DISPOSITIVO PROTETOR DE MOTOR ELéTRICO". Compreendendo: um estator tendo um enrolamento de marcha (11) e um enrolamento de partida (12); uma fonte (F) de alimentação de corrente aos referidos enrolamentos de marcha (11) e de partida (12); chaves de potência (60), cada uma conectando um dos enrolamentos de marcha (11) e de partida (12) à fonte (F), quando em uma condição fechada, dito dispositivo compreendendo pelo menos uma chave térmica (70) conectando operativa e eletricamente a fonte (F) às chaves de potência (60) e sendo termicamente acoplada a essas últimas, de modo a detectar a temperatura em ditas chaves de potência (60) e a interromper a corrente a essas últimas, quando a temperatura em qualquer uma de ditas chaves de potência (60) atingir um determinado valor predefinido e superior a um respectivo valor previamente estabelecido de temperatura máxima de funcionamento das chaves de potência (60)."ELECTRIC MOTOR PROTECTIVE DEVICE". Comprising: a stator having a travel winding (11) and a starting winding (12); a power supply (F) for said running (11) and starting (12) windings; power switches (60), each connecting one of the start (11) and start (12) windings to the source (F), when in a closed condition, said device comprising at least one thermal switch (70) operatively connecting and electrically source (F) to the power switches (60) and being thermally coupled thereto so as to detect the temperature in said power switches (60) and to interrupt the current to those latter when the temperature in either said power switches (60) reach a predefined value and greater than a predetermined value of the maximum operating temperature of the power switches (60).
