The invention discloses a self-provided vibration reduction type superconducting current lead measuring device for a fusion device. The measuring device comprises a vacuum cavity, wherein a vacuum signal wire core seat and a vacuum extraction opening are arranged at a side wall of the vacuum cavity, a flange is arranged at the top of the vacuum cavity, a refrigerator is connected with the flange through a vacuum corrugated pipe, and each of a primary cold head and a secondary cold head of the refrigerator extends into the vacuum cavity; a current lead vacuum fixing seat is arranged on the flange, the room temperature ends of two pairs of superconducting current leads are fixed on the fixing seat, a high-temperature superconducting section and a low-temperature superconducting section extend into the vacuum cavity, the high-temperature superconducting section is connected with the primary cold head through a copper block, and the low-temperature superconducting section is connected withthe secondary cold through the copper block. The measuring device disclosed by the invention is reasonable in structure, and effectively reduces the influence on a measurement result by the vibrationcaused by the work of the refrigerator, and improves the measurement precision of the current lead; the phenomenon of blowing off when the current lead is quenched can be avoided by taking the copperblock as heat buffer, and two pairs of current leads can be simultaneously measured, thereby improving the measurement efficiency.
