Abstract
본 발명은 유도전동기의 인버터 과부하 보호장치에 관한 것으로, 종래의 인버터 과부하 보호장치는 부하(모터)에 공급되는 전류를 3개의 전류센서로 감지하고 이들을 다시 디지탈 변환시키는 A/D변환기가 요구되므로 부피상승과 원가상승이 초래되고, 과부하 반한특성의 참조 테이블을 32개 워드단위로 구성해야 되므로 마이컴의 메모리를 차지하는 용량이 커지게 되는 등의 문제점을 해결하기 위한 것이다.The present invention relates to an inverter overload protection device of an induction motor, and the conventional inverter overload protection device requires an A / D converter for sensing current supplied to a load (motor) with three current sensors and converting them again. This is to solve the problems such as the increase of the cost and the increase of the cost, and the need to configure the reference table of the overload characteristic in 32 word units, which increases the capacity of the microcomputer memory.
따라서 본 발명은 전류센서의 사용을 배제하고, 인버터의 전류전원단에서 전류변화를 검출하며, 검출전류를 기준값과 비교한 결과로 마이컴이 반한시 특성을 수행하도록 하므로서 제품의 소형 경량화 및 회로구성의 간소화, 원가절감을 기하고 소요메모리 용량을 줄여줄 수 있도록한 것으로, 인버터에 적용한다.Therefore, the present invention eliminates the use of the current sensor, detects the current change at the current power supply terminal of the inverter, and compares the detected current with the reference value, so that the microcomputer performs the inverse time characteristic, thereby reducing the size and weight of the product It is designed to simplify, reduce costs, and reduce required memory capacity. It is applied to inverters.
