Abstract
La presente invención se refiere a mejoras en sistema de control en tándem de contactores electromagnéticos, para protección térmica de un motor bidireccional, de CA, que incluye primero y segundo contactos relacionado con los sentidos opuestos de rotación de un motor alimentado con CA por medio de los contactores un contactor está inactivo para pasar la CA al motor cuando el segundo está inactivo para pasar corriente al motor, caracterizado porque un generador de imágen térmica y una unidad de control de protección para un contactor; segundo generador de imágen térmica y segunda unidad de control de protección para el segundo contactor, cada generador de imágen térmica responde auna señal que representa la corriente de línea suministrada al motor por el contactor respectivo para generar una señal que represente el estado térmico del motor y la unidad de control de protección correspondiente responde a la señal que representa y a una señal de limite, la línea de comunicación bidireccional que interconecta unidades de control de protección opuestas para transferir la señal que representa el estado excede ade la señal límite: línea de comunicación bidireccional que interconecta unidades de control de protección opuestas para transferir la señal que representa el estado, derivada del generador de imágen térmica del segundo extremo hasta el generador de imágen térmica del segundo contactor en el segundo extremo, la unidad de control de protección de un contactor activo responde a ala señal que representa el estado térmico del motor del último contactor activo y a la señal que representa el estado térmico del último contactor al ocurrir una inversión de la rotación del motor.
