Description

Technical Field

[0001] The utility model belongs to the technical field of test equipment, in particular to a cable aging test device. Background Art

[0002] Cables will age due to environmental factors during use. Common environmental factors include high temperature, humidity, vibration, etc. In special environments such as nuclear reactors, they are also exposed to radiation. The aging resistance of cable materials is an important means to evaluate the life of cables. Existing cable aging tests are performed by placing the cables in an oven. Although the aging test of the cables can be achieved, manual devices are required when placing the cables in the oven, and the hands are placed deep inside the oven, which may cause burns, resulting in a low safety factor of the device.

[0003] After searching, the Chinese patent document (authorization announcement number CN209264603U) shows that the utility model discloses a thermal aging test device for cable materials, which includes a base, a vertical pole, a fixed block and a detachable branch; two fixed blocks arranged up and down are fixed on the vertical pole, and the detachable branch is installed on the fixed block, and the second locking parts on the upper and lower detachable branches respectively lock the two ends of the test piece, so that the test piece is arranged vertically, that is, the same as the wind direction in the oven, so that the wind of the oven can pass through the test piece evenly and fully; the detachable branch can be added or reduced according to the size of the oven. Although this patent can realize the aging test of the cable, it requires manual assistance when placing the cable in the oven, and the hand is deep inside the oven, which may cause scalding, making the safety factor of the device low.
