Claims (1)
- 단일고정자권선과 전원의 접속상태를 변환함으로써 고정자의 극수를 변환하는 극수변환전동기에 있어서, 상기 단일고정자권선과, 상기 전원의 접속부에 설치한 케이블접속기와, 상기 케이블접속기의 착탈상태를 검출하는 검출수단과, 상기 검출수단으로부터의 검출신호에 기준하여 상기 극수에 대응하는 전동기 보호장치간의 회로절환을 하는 제어회로를 구비한 것을 특징으로 하는 극수변환전동기의 구동장치.요약서이 발명은 종래의 극수변화전동기의 구동장치에 있어서, 저속측 주회로 투입접촉기 및 고속측 주회로투입접촉기를 차단기로 사용하지 않으면 안되므로 중앙의 전기실에 설치되는 절환반 및 기타 케이블등 설비가대형화하고 광대한 공간이 필요하여 비용의 증가를 초래하는 문제점을 해소시킨 것으로서, 극수변환전동기의 단일고정자권선과 전원의 접속부에 설치한 케이블접속기와, 이 케이블접속기의 착탈상태를 검출하는 검출수단과, 이 검출수단으로부터의 검출신호에 기준하여 상기 극수에 대응하는 전동기 보호장치간의 회로절환을 하는 제어회로를 구비하여서, 단일속도의 전동기와 대략 같은 장치공간에 염가로 구성할 수 있는 극수변환전동기의 구동장치를 제공할 수 있는것이다.
