The invention relates to a containment assembly, and concretely relates to an electrical penetration device for a containment. The electrical penetration device is characterized in that the electricalpenetration device comprises a casing tube, a conductive core is arranged in the casing tube concentrically, the external diameter of the conductive core is smaller than that of the casing tube, bothends of the conductive core respectively extend out from both ends of the casing tube, insulating sleeves are respectively arranged at both ends of the conductive core, one ends of the insulating sleeves are located in the casing tube, the other ends are located outside the casing tube, and a space between the inner wall of the casing tube and the conductive core between the two insulating sleeves is filled with an insulating material; and a heat shrinking tube sleeves every insulating sleeve located inside the casing tube, and a stuffing box is arranged between every heat shrinking tube andthe casing tube. The electrical penetration device has a small size, and can be used in a reactor needing a compact arrangement.
Description
technical field [0001] The invention relates to a containment vessel assembly, in particular to an electrical penetration device for the containment vessel. Background technique [0002] Electrical penetrations are special electrical equipment installed on the wall of the reactor containment for cables to pass through the containment. Under normal and various accident conditions, including: earthquakes and loss of water accidents, the electrical penetrations should be able to ensure the integrity of the reactor containment, prevent the leakage of radioactive materials, and at the same time maintain the electrical and signal integrity inside and outside the containment. continuity. [0003] At present, the electrical penetration device for containment used in the industry includes a support tank, and a plurality of cables run through the support tank. All have protective covers, and the section of cable located in the support tank has a sealing mechanism. This kind of elec...
