본문에 상술한 바와 같이 전기, 수도, 가스공급장치의 개폐장치의 개폐작동용 입력부에 접점릴레이(5)와 개폐릴레이(6)를 설치하여 필요시 관리부(1)의 지시에 의거 작동되는 개폐기(1a)가 개폐되는 신호에 따라 접점릴레이(5)의 접점(5a)이 작동하면 개폐릴레이(6)의 코일이 여자되어 접점(6a)을 개폐시킬 수 있게한 전화시험회선을 이용한 미량전류로서 전기, 수도, 가스의 공급부 원격개폐장치.As described above, a contact relay 5 and an opening / closing relay 6 are installed in the input unit for opening / closing operation of the opening / closing device of the electricity, water and gas supply device, and the switch is operated according to the instruction of the management unit 1 when necessary. When the contact 5a of the contact relay 5 is operated in accordance with the signal 1a) is opened and closed, the coil of the open / close relay 6 is excited to generate electricity as a microcurrent using a telephone test line that enables the contact 6a to be opened and closed. Remote switchgear for water, gas and gas supply. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
