APPARATUS FOR DETECTING THE FAULT OF REACTORS AND SHORT CIRCUIT SWITCH FOR THESE REACTORS TO LIMIT MOTOR STARTING CURRENT

摘要

The present invention relates to a reactor for starting a motor and a reactor protector for detecting a switch failure for short circuiting of a reactor. Specifically, the present invention relates to a detection device for detecting a failure of a reactor in which an initial driving current and a voltage of a motor are dropped so that the motor is driven. An input unit connected to an upper end or a lower end of the reactor and a lower end of a power supply terminal for supplying power to the motor, and an input unit for inputting a voltage and current value applied from the power supply terminal and a voltage and current value of the upper or lower reactor; A data storage unit connected to the input unit and storing an information value inputted therein; An operation control unit connected to the data storage unit to compare the voltage and current values of the normal and the currently input voltage and current values stored in the data storage unit to display the compared information to the user; A digital input unit connected to the operation control unit to input a digital input value set by a user; A communication conversion unit connected to the operation control unit to transmit information outputted from the operation control unit to the terminal, and receiving a control signal of the terminal and transmitting the information to the operation control unit; An output unit connected to the operation control unit and outputting a signal output from the operation control unit to an external device; A terminal connected to the communication converter to display information transmitted from the communication converter, and to transmit a control signal input by the user to the communication converter; It relates to the motor control reactor and the data storage unit, the output unit and the communication conversion unit constant voltage unit for applying a constant voltage; and a reactor for starting the reactor and reactor short circuit switch fault detection reactor.;Reactor, Reactor Protector, Motor, Failure Detection
