Abstract
The utility model relates to a high-temperature fusing protection device of a rotating component. The high-temperature fusing protection device comprises an installation seat, a probe, two thermal fuses and a shielding cable. The two thermal fuses are arranged in parallel and are sealed in the probe. The shielding cable is used for connecting the two thermal fuses, and the two thermal fuses are sleeved with heat-conductive insulation sleeve pipes. The heat-conductive insulation sleeve pipes are filled with heat-conductive insulation paste. The high-temperature fusing protection device of the rotating component has the advantages of being impact vibration resistant, high-temperature resistant, high in reliability, suitable for bad environment, and the like, meanwhile, the two parallel-connected thermal fuses are arranged in the high-temperature fusing protection device, even one thermal fuse fails, the other thermal fuse still can normally give out an alarm, and temperature protection with high reliability is provided.
Description
[technical field]
The utility model relates to a kind of high temperature fuse protecting device, is specifically related to a kind of high temperature fuse protecting device of turning unit, and it is applied to belong to train cooperating equipment technical field in turning unit under high-speed train.
