Abstract

A power supply control device of a nitrogen gas generator includes: a pipe having a nitrogen gas inlet for receiving input of nitrogen gas from a nitrogen gas generator that compresses air by a compressor to separate the nitrogen gas from the air, and a nitrogen gas outlet for outputting, to outside, the nitrogen gas received by the nitrogen gas inlet; a pressure gauge that measures pressure inside the pipe; a flowmeter that measures a flow rate of the nitrogen gas flowing inside the pipe; and a control unit that controls supply of power to the compressor and shut-off of the supply of the power in accordance with a measurement result of at least one of the pressure gauge and the flowmeter.
