The present invention relates to a multi-function power receiving facility for supplying power to railway facilities which comprises: a disconnector for busbars (100); a first transformer (200); a circuit breaker (300); a second transformer (400); a disconnector for lines (500); a ground switch for maintenance (600); first to fourth check valves (CV1, CV2, CV3, CV4); first to fourth electromagnetic valves (EV1, EV2, EV3, EV4); first, second, and third pressure sensors (PS1, PS2, PS3); first and second temperature sensors (TS1, TS2); an earth Leakage Detection Sensor (ELS); a water-cooling device (900); a control unit (1000); a transmitter (1100); a power supply unit (1200); and a lighting unit (1300). According to this, the internal pressure of a first enclosure (110), a circuit breaker enclosure (310), and a second enclosure (510) filled with insulating gas (SF6 gas) is monitored (measured) in real time to detect the leakage of the insulating gas (SF6 gas). The enclosures with the insulating gas (SF6 gas) leaking receive the insulating gas (SF6 gas) from the adjacent enclosures to maintain insulation performance. The problem of poor performance is resolved by lowering pressure increase due to heat. The use of external power can be reduced, making it economical. Convenience can be improved as work can be done at night. Workers can be safely protected from the risk of electric shock.
본 발명은 모선용 단로기(100)와 제1변류기(200), 차단기(300), 제2변류기(400), 선로용 단로기(500), 보수용 접지개폐기(600), 제1 내지 제4체크밸브(CV1,CV2,CV3,CV4), 제1 내지 제4전자밸브(EV1,EV2,EV3,EV4), 제1·2·3압력센서(PS1,PS2,PS3), 제1·2온도센서(TS1,TS2), 누전감지센서(ELS), 수냉각장치(900), 제어부(1000), 송신기(1100), 전원공급유닛(1200) 및 조명유닛(1300)으로 구성된 철도시설물 전력공급을 위한 복합기능 수전설비에 관한 것으로서, 이에 의하면 절연가스(SF6가스)가 충진된 제1외함(110)과 차단기외함(310) 및 제2외함(510)의 내압을 실시간으로 감시(측정)하여 절연가스(SF6가스)의 누출을 감지하고, 절연가스가 누출된 외함은 인접한 외함으로부터 절연가스를 공급받아 절연성능이 유지될 수 있도록 하며, 열로 인한 압력증가를 낮춰 성능이 떨어지는 문제를 해소하며, 외부전원의 사용을 줄일 수 있어 경제적이며, 야간에도 작업이 가능해 편의성을 개선할 수 있으며, 감전의 위험으로부터 작업자를 안전하게 보호할 수 있는 기술적인 특징이 있다.
