Abstract
본 발명은 대규모 단상부하에 의해 흐르는 불평형전류가 발생시키는 전압불평형율을 완화시키도록 한 단상식 부하불평형 부분보상장치에 관한 것이다.
기존의 3상형 불평형보상장치에 비하여 불평형부하의 일부를 보상할 경우 그 효과가 우수하다.
더구나, 주회로가 간단하고 직렬공진과 같은 위험성이 적으며 전력배선, 차단기, 개폐기, 배전반도 간단해져 대규모 단상부하 수전시 매우 유리하다.
일반적인 지상역률의 선간단상부하의 일부를 평형시키기 위하여 리액터를 부하가 연결된 두상간의 위상보다 120°앞선 두상간에 가하여 흐르는 무효전력에 의하여 역상전류의 크기를 저감시킨다.
본 발명은 전기 철도부하, 단상아크로를 공급하는 변전소에 설치되는 불평형 보상장치에 적용될 수 있다.

Claims (2)
- 3상계통에서 대형의 단상부하(1)에 의해 불평형 전류가 흐르게 되면 전압불평형이 발생할 때 두 상간에만 보상용 무효전력(2)을 가함으로서 불평형을 완화시켜 주는 것을 특징으로 하는 단상식 부하 불평형 부분보상장치.
- 제1항에 있어서, 상기 보상용 무효전력(2)은 고정형 또는 가변형인 것을 특징으로 하는 단상식 부하 불평형 부분보상장치.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
