Abstract

DISPOSITIVO DE SEGURIDAD PARA ALMOHADILLAS, MANTAS ELECTRICAS Y SIMILARES. COMPRENDE MEDIOS (4) PARA LA DESCONEXION DEL CIRCUITO CALEFACTOR (5) DE LA ALMOHADILLA (1) AL PRODUCIRSE UN FALLO EN EL AISLAMIENTO A CAUSA DE LA FUSION DEL MISMO POR CALENTAMIENTO DEL CIRCUITO CALEFACTOR (5). SE CARACTERIZA POR EL HECHO DE QUE LOS MEDIOS (4) PARA LA DESCONEXION DEL CIRCUITO CALEFACTOR (5) COMPRENDEN UN DISPOSITIVO DE CONMUTACION (14) EXCITABLE POR TENSION, UN PRIMER DIODO (11) CONECTADO EN PARALELO CON UNA RESISTENCIA (12), UN SEGUNDO DIODO (7) CONECTADO EN SERIE CON EL CIRCUITO CALEFACTOR (5) Y UN DISPOSITIVO DE CORTE (13). EL CORTE DEL CIRCUITO (5) SE PRODUCE AL ACTIVARSE EL DISPOSITIVO DE CONMUTACION (14) CUANDO TIENE LUGAR UN FALLO EN EL AISLAMIENTO. SE MEJORA LA SEGURIDAD DE LA ALMOHADILLA (1) CON UN COSTE DE FABRICACION REDUCIDA.SAFETY DEVICE FOR PADS, ELECTRIC BLANKETS AND SIMILAR. IT INCLUDES MEANS (4) FOR THE DISCONNECTION OF THE HEATING CIRCUIT (5) OF THE PAD (1) WHEN A FAILURE IN THE INSULATION DUE TO THE FUSION OF THE SAME DUE TO HEATING OF THE HEATING CIRCUIT (5). IT IS CHARACTERIZED BY THE FACT THAT THE MEANS (4) FOR THE DISCONNECTION OF THE HEATING CIRCUIT (5) INCLUDE A SWITCHING DEVICE (14) EXCITABLE BY VOLTAGE, A FIRST DIODE (11) CONNECTED IN PARALLEL WITH A RESISTOR (12), A SECOND DIODE (7) CONNECTED IN SERIES WITH THE HEATING CIRCUIT (5) AND A CUTTING DEVICE (13). CIRCUIT CUTTING (5) OCCURS WHEN THE SWITCHING DEVICE IS ACTIVATED (14) WHEN A FAULT IN INSULATION TAKES PLACE. PAD SAFETY IMPROVES (1) WITH A REDUCED COST OF MANUFACTURE.
