The invention relates to a spark gap zero detection device, in particular to a cage rolling type spark gap zero detection device. The cage rolling type spark gap zero detection device is characterized by comprising a bracket and cage rotors, wherein the bracket consists of a horizontal edge and two vertical edges fixed at both sides of the horizontal edge; and the cage rotors are fixed inside thetwo vertical edges of the bracket through a rotating shaft. The cage rolling type spark gap zero detection device has a simple structure and is convenient and efficient to use. The defects of the existing spark gap zero detection device are overcome. In the measuring process, a triangular stable structure is formed by taking a human body as a supporting point; and an operator does not need to carry out lift-up and put-down operation and only needs to drag an operating rod to ensure the rotors to carry out rotational measurement, so that the measuring time is greatly shortened and the labor intensity of the operator is reduced. Meanwhile, the number of spark gaps is effectively reduced, so that the measurement is more accurate and the measurement error is reduced.
