제1도는 본 고안의 회로도.1 is a circuit diagram of the present invention.

Claims (1)

단상 전원으로 3상 모우터를 구동시키기 위한 위상 변환 회로에 있어서, △결선된 3상 콘덴서(C2)를 통상의 모우터(M)의 각 단자(U),(V),(W)에 각각 접속하고 그 접속점에서 △결선용 릴레이의 a접점(RDa)을 각각 통하여 일측이 공통 접지된 Y결선용 릴레이의 a접점(RSa)과 상기 모우터의 각 단자(X),(Y),(Z)를 접속하며, 모우터의 단자(U),(V)는 단상입력단자(R),(S)에, 단자(Y),(Z)는 단상 콘덴서(C1)의 양단에 접속하고, 동한 단상입력단자(R),(S) 사이에 정지스위치(Sb), 기동스위치(Sa), 타이머(T), 과전류 차단기의 b접점(OCRb)를 직렬로 접속하며, 상기 기동스위치(Sa) 양단에는 타이머의 a접점(Ta)을, 타이머(T)의 양단에는 타이머의 지연 b접점(Tdb), △결선용 릴레이의 b접접(RDb), Y결선용 릴레이(RS)의 직렬회로와 타이머의 지연 a접접(Tdb), Y결선용 릴레이의 b접점(RSb), △결선용 릴레이(RD)의 직렬회로를 병렬로 접속하여, 단상 입력전원이 인가되는 3상 모우터의 단자중 어느 한 단자에 단상 콘덴서를 연결하여 이에 유기되는 여자전류를 입력전원이 연결되지 않은 단자에 인가시켜 모우터를 정상 운전시키며, 3상 모우터의 기동시는 Y결선이 되게 하고, 기동완료 시간으로 설정되는 타이머의 지연동작에 의하여 기동완료 후에는 △결선으로 변환되게 함을 특징을 하는 위상변환기.In a phase conversion circuit for driving a three-phase motor with a single-phase power supply, the three-phase condenser C 2 connected to each terminal U, V, and W of the ordinary motor M is connected. The contact a is connected to each other and a contact RSa of the Y-connecting relay in which one side is commonly grounded through a contact RDa of the relay for connection, and terminals X, Y of the motor, and ( Z), the terminals U and V of the motor are connected to the single phase input terminals R and S, and the terminals Y and Z are connected to both ends of the single phase capacitor C1. The stop switch Sb, the start switch Sa, the timer T, and the b contact OCRb of the overcurrent breaker are connected in series between the single-phase input terminals R and S, and the start switch Sa Timer a contact Ta of the timer on both ends, delay b contact Tdb of the timer on both ends of the timer T, b contact RDb of the relay for connection, and the serial circuit of the relay Y for connection Delay a contact (Tdb), b contact relay (Yb) of Y connection relay, △ connection Connect the series circuit of the ray RD in parallel, connect the single-phase capacitor to one of the terminals of the three-phase motor to which the single-phase input power is applied, and apply the excitation current induced therein to the terminal to which the input power is not connected. The motor is operated normally and the phase shifter is Y-connected when the three-phase motor is started, and is converted to △ -connected after the start-up by the delay operation of the timer set to the start-up time. . ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
