Zusammenfassung:Provided is a current transformer for a power supply to transform a primary current flowing in a distribution line into a secondary current through electromagnetic induction. According to the present invention, the current transformer for a power supply comprises: a current transformer connected to a plurality of terminals on the basis of a predetermined number of turns to adjust an output current; and a short circuit switch short-circuiting both ends of the current transformer to prevent a high voltage generated according to opening of the output terminal of the current transformer. Accordingly, the current transformer can supply power in response to changes in a distribution line, the current transformer can be easily installed on underground transmission and distribution lines, and the current transformer can provide an increased waterproof/dustproof function. 본 명세서는 배전선로에 흐르는 1차 전류를 전자기 유도를 통해 2차 전류로 변환하는 전원공급장치용 전원용 변류기를 제공하며, 상기 전원용 변류기는, 출력 전류를 조절할 수 있도록 일정한 턴수를 기준으로 복수 개의 단자에 연결되는 변류기; 및 상기 변류기의 출력 단자의 개방에 따라 발생되는 고전압을 방지하기 위해 상기 변류기의 양단을 단락시키는 단락 스위치를 포함함으로써, 배전 선로의 변화에 대응하여 전원 공급이 가능하고, 지중 송배전 선로에 설치가 용이하고 방수/방진 기능이 개선된 전원 공급 장치용 전원용 변류기를 제공할 수 있다.
