Abstract
UN APAREJO ELEVADOR (5) ACCIONADO POR UN MOTOR ASINCRONO DE CORRIENTE TRIFASICA (4) CON INDUCIDO EN CORTOCIRCUITO DEBE SER OPERADO DESDE UNA RED DE CORRIENTE ALTERNA MONOFASICA O MULTIFASICA (1) CON UNA VELOCIDAD DE ELEVACION VARIABLE. ESTO ES POSIBLE POR UN CONVERTIDOR DE CIRCUITO INTERMEDIO DE TENSION (2) QUE ES ALIMENTADO DESDE UNA RED A PARTIR DE UNA RED DE CORRIENTE ALTERNA MONOFASICA O MULTIFASICA (1) Y DESDE EL LADO DE LA CARGA UNA RED DE CORRIENTE TRIFASICA (3), CON LA QUE ESTA UNIDA EL MOTOR ASINCRONO (4). LA FRECUENCIA DE LA RED DE CORRIENTE TRIFASICA (3) Y, CON ELLO, TAMBIEN LA VELOCIDAD DE ELEVACION DEL APAREJO ELEVADOR PUEDE SER SUPERIOR A LA FRECUENCIA DE LA RED DE CORRIENTE ALTERNA MONOFASICA O MULTIFASICA (1) Y LA VELOCIDAD DE ELEVACION RESULTANTE DE ELLO. ENTRE LA RED DE CORRIENTE DE TRIFASICA (3) Y EL CONVERTIDOR DE CIRCUITO INTERMEDIO DE TENSION (2) HAY PREVISTO UN REGULADOR (6) QUE LIMITA LA FRECUENCIA MAXIMA EN FUNCION DE LA CARGA.A LIFTING EQUIPMENT (5) DRIVEN BY AN ASYNCHRONOUS THREE-PHASE CURRENT MOTOR (4) WITH A SHORT CIRCUIT INDUCED MUST BE OPERATED FROM A SINGLE-PHASE OR MULTI-PHASE ALTERNATING CURRENT NETWORK (1) WITH A VARIABLE LIFTING SPEED. THIS IS POSSIBLE BY AN INTERMEDIATE VOLTAGE CIRCUIT CONVERTER (2) WHICH IS SUPPLIED FROM A NETWORK FROM A SINGLE-PHASE OR MULTI-PHASE ALTERNATING CURRENT NETWORK (1) AND FROM THE LOAD SIDE A THREE-PHASE CURRENT NETWORK (3), WITH WHICH THE ASYNCHRONOUS MOTOR IS UNITED (4). THE FREQUENCY OF THE THREE-PHASE CURRENT NETWORK (3) AND, WITH IT, ALSO THE LIFTING SPEED OF THE LIFTING EQUIPMENT MAY BE HIGHER THAN THE FREQUENCY OF THE SINGLE-PHASE OR MULTI-PHASE ALTERNATING CURRENT NETWORK (1) AND THE RISING SPEED . BETWEEN THE THREE-PHASE CURRENT NETWORK (3) AND THE INTERMEDIATE VOLTAGE CIRCUIT CONVERTER (2) A REGULATOR (6) IS PROVIDED TO LIMIT THE MAXIMUM FREQUENCY DEPENDING ON THE LOAD.
