The invention discloses a composite coil type structure for direct current long pulse current measurement. The composite coil type structure for direct current long pulse current measurement includesa composite coil and a subtraction circuit, wherein the composite coil includes a positive polarity coil and a negative polarity coil; the positive polarity coil is provided with taps P+ and P-; P+ isa coil terminal tap, and P- is a loop terminal tap; the negative polarity coil is provided with taps N+ and N-; N+ is a coil terminal tap, and N- is a loop terminal tap; and the subtraction circuit includes four resistors R1, R2, R3 and R4, and an operational amplifier. The composite coil type structure for direct current long pulse current measurement utilizes the structure that the composite coil matches the subtraction circuit, and for the application occasion heavily influenced by trigger noise, the composite coil type structure for direct current long pulse current measurement enables the differential signal amplitude input by an integrator to be increased by one time, so that the trigger noise amplitude can be attenuated greatly and the signal to noise ratio of the original signal can be improved, and then the post-stage circuit can conveniently uses a high gain amplication signal, and then the burr noise in the integration result can be eliminated, and finally the measuring accuracy can be improved.
