전자식 모터 제어센터(MCC)에서의 Y-△ 기동처리 방법Y- △ start processing method in electronic motor control center (MCC)

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 전자식 모터 제어기의 회로도.1 is a circuit diagram of an electronic motor controller.

제2도는 모터 기동시의 시간-전류 곡선을 타나낸 그래프.2 is a graph showing a time-current curve when the motor is started.

Claims (2)

전자식 모터 제어센터(MCC)에서의 Y-△기둥 처리 방법에 있어서, 모터에 연결되는 3상 교류 전력선으로부터 전류를 검출하여 검출된 직류전류를 미리 설정된 모터의 정격 전류값이 따라 디지털 값으로 변환하여 중앙처리장치(CPU)로 공급하는 단계와, 모터 기동시 모터의 시간에대한 전류의 곡선에서의 제1의 상태, 제2의 상태 및 제3의 상태의 레벨을 설정하는 단계와, 모터의 운전 명령에 따라 Y기동을 행하기 위한 릴레이를 여자시키는 제어신호를 발생하는 단계와, 상기 전류 곡선의 제2상태 및 제3의 상태를 판단하고, 모터 기동시의 전류곡선이 제3의 상태에 있는 것을 감지하였을 때 즉시 상기 Y기동 릴레이를 석방하여 Y접점을 개방시키고, 모터에 흐르는 전전류가 0이 된 것을 확인한 후에 △기동 릴레이를 여자시키게 한 제어신호를 발생하는 단계로 이루어진 것을 특징으로 하는 전자식 모터 제어 센터에서의 Y-△기동 처리방법.In the Y- △ pillar processing method in an electronic motor control center (MCC), a current is detected from a three-phase AC power line connected to the motor and the detected DC current is converted into a digital value according to the rated current value of the preset motor. Supplying to a central processing unit (CPU), setting a level of a first state, a second state, and a third state in a curve of current with respect to the time of the motor when the motor is started, and driving the motor Generating a control signal for exciting the relay for starting Y according to the command; judging the second state and the third state of the current curve; and wherein the current curve at the motor start is in the third state. The Y start relay is immediately released when it detects that the Y contact relay is detected, and after confirming that the total current flowing to the motor is zero, the control signal is made to excite the start relay. Y- △ start-up processing method in an electronic motor control center, characterized in that binary luer. 제1항에 있어서, 상기 모터 기동시 시간에 대한 전류곡선의 제1상태는 모터 정격전류의 130% 레벨까지로 설정하고, 제2의 상태는 상기 130% 레벨에서부터 110%의 레벨까지 설정하며, 제3의 상태는 상기 110% 레벨 이하로 설정되는 것을 특징으로 하는 전자식 모터제어 센터에서의 Y-△기동 처리방법.The method of claim 1, wherein the first state of the current curve with respect to the time at which the motor is started is set to a level of 130% of the rated current of the motor, and the second state is set from the 130% level to a level of 110%, And the third state is set to be below the 110% level. ※참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is to be disclosed based on the initial application.
