The invention provides an oil paper insulating moisture quantitative control device for a headspace type air accommodation method. The device comprises a tank body, an air aerator and a control circuit, wherein an opening is formed in the top of the tank body; a first metallic air introduction tube is arranged on a side wall of the tank body; a first valve, a first air flowmeter and a first humidity sensor are sequentially arranged on the first metallic air introduction tube in an air flowing direction; a second metallic air introduction tube is arranged on the other side wall of the tank body; a second humidity sensor, a second air flowmeter and a second valve are sequentially arranged on the second metallic air introduction tube in the air flowing direction. Due to adoption of devices ofthe humidity sensor, the flowmeters, and the like, and real-time humidity monitoring and flow adjustment on input/out air of the device can be achieved; as an oil paper test sample in the device is placed inside insulating o
