A device and method for limiting a short circuit current for a submarine are provided. The device includes an electronic switch which is disposed inside the pressure body of a submarine and determining a path through which a current flows, a control board which is disposed inside the pressure body and transmits a command for a switching operation to the electronic switch, a current sensor which is disposed inside the pressure body and detects whether a short circuit current is generated in an electronic component in the pressure body and transmits a detection result to the control board when the short circuit current is generated, and a resistor which is disposed outside the pressure body and in which a current flows according the opening of the electronic switch when the short circuit current is generated. The size of the whole device can be miniaturized.

    잠수함용 단락전류 제한장치 및 방법이 제공된다. 상기 잠수함용 단락전류 제한장치는, 잠수함의 압력 선체의 내부에 배치되고, 전류가 흐르는 패스(path)를 결정하는 전자스위치, 상기 압력 선체의 내부에 배치되고, 스위칭 동작에 대한 명령을 상기 전자스위치로 전송하는 제어보드, 상기 압력 선체의 내부에 배치되고, 상기 압력 선체 내의 전자부품에 단락전류 발생여부를 감지하고, 단락전류 발생 시 감지 결과를 상기 제어보드로 전송하는 전류센서, 및 상기 압력 선체의 외부에 배치되고, 단락전류 발생 시 상기 전자스위치의 개방에 따라 전류가 흐르는 저항기를 포함한다.
