The present invention relates to a power supply apparatus for 25 Kv for supplying power to a streetcar rail, which comprises: a busbar disconnector (100); a first deflector (200); a circuit breaker (300); a second deflector (400); a rail disconnector (500); a maintenance grounding opener/closer (600); first through fourth check valves (CV1, CV2, CV3, CV4); first through fourth electronic valves (EV1, EV2, EV3, EV4); first through third pressure sensors (PS1, PS2, PS3); first and second temperature sensors (TS1, TS2); a water cooler apparatus (900); a control unit (1000); a transmitter (1100); and a power supply unit (1200). According to the present invention, the internal pressure of a first enclosure (110) filled with insulation gas (SF6 gas), a circuit breaker enclosure (310), and a second enclosure (510) is monitored (measured) in real time, and the leakage of insulation gas (SF6 gas) is detected. In addition, any enclosure with an insulation gas leak can receive insulation gas from a nearby enclosure, thereby maintaining insulation performance. In addition, the problem of lowered performance can be solved by reducing the increase in pressure due to heat. In addition, the use of external power can be reduced, which is economical.

    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), 수냉각장치(900), 제어부(1000), 송신기(1100) 및 전원공급유닛(1200)으로 구성된 전차선 전력공급을 위한 25Kv용 전력공급장치에 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 경제적인 이다.
