SYSTEM OF SENSING HIGH TEMPERATRUE BY DEVICE OF HIGH VOLTAGE DISTRIBUTING BOARD, LOW VOLTAGE DISTRIBUTING BOARD, DISTRIBUTING BOARD, MOTOR CONTORL BOARD USING MULTI-ARRAY INFRARED SENSOR

摘要

A degradation sensing system of the present invention comprises: a multi array infrared ray sensor which senses temperatures according to a power device of a high voltage distribution board, a low voltage distribution board and a motor control board; an initial temperature memory which stores an initial temperature of the power device; a reference temperature memory which stores a reference temperature range in advance to judge degradation according to the power device; a degradation judgment module which judges degradation according as a difference between the temperature of the power device sensed by the multi array infrared ray sensor and the initial temperature of the corresponding power device stored in the initial temperature memory is within a reference temperature range of the corresponding power device stored in the reference temperature memory; and a warning module for outputting a warning signal according to the judgment result of the degradation judgment module. By the degradation sensing system per device of the high voltage distribution board, the low voltage distribution board and the motor control board using the multi array infrared ray sensor, the present invention has the effect of being able to judge degradation state per individual part accurately instead of the prior method, by configuring the system to perform the judgment individually by setting each temperature range as to the degradation state or a warning state according to various power devices comprised in the high voltage distribution board, the low voltage distribution board and the motor control board. Also, in case of a three-phase transformer, the system can judge accurate degradation and degradation possibility accurately, by coping with temperature variation per phase.
