Abstract
본 발명은 전동기 보호계전기에 관한 것으로, 종래에는 동작오차도 크고 동작전류의 표시도 하지 못하는등 사용상의 문제점이 있었다. 따라서 종래의 문제점을 해결하기 위하여 본 발명은 마이크로프로세서를 이용하여 동작시간과 동작전류의 설정을 마음대로 설정할 수 있고, 동작전류를 수치적으로 표현이 가능하여 과부하보호, 결상 및 역상 등을 검출하는 방식을 소프트웨어적으로 처리하여 보호기능을 구현하는데 적당하도록 한 효과가 있다.The present invention relates to a motor protection relay, conventionally has a problem in use, such as a large operating error and not display the operating current. Therefore, in order to solve the conventional problems, the present invention can set the operating time and the operating current at will using a microprocessor at will, and can express the operating current numerically to detect overload protection, phase loss and reverse phase. The effect is that the software is processed to make it suitable for implementing the protection function.
