Abstract
Description
Claims (4)
- 삭제
- 전력공급 계통으로부터 공급되는 특고압 전력을 특고압 붓싱을 경유하여 저압으로 변환한 후 과전류 보호용 퓨즈를 통해 부하측으로 전원을 공급하기 위한 변압기에 있어서,상기 전력공급 계통에서 상기 특고압 붓싱으로 입력되는 전원을 개폐하기 위한 특고압 전력용 스위치가 상기 변압기의 본체에 돌출되게 설치되는 것을 특징으로 하는 개폐기가 구비된 지상변압기.
- 삭제
- 제 2항에 있어서,상기 특고압 전력용 스위치는 상기 지상변압기의 외부에 버튼이나 스틱으로 구비되어 전력을 개폐하는 것을 특징으로 하는 개폐장치가 내장된 지상변압기.
