Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cable ducts, and particularly relates to a segmented special cable tie for fixing a duct cover. Background Art
[0002] In large hydroelectric power plants, cable ducts are distributed in every corner of the generator set, with different sizes and shapes. In particular, some cable ducts located in the core area, such as the cable duct for temperature measuring resistors outside the thrust bearing, are affected by the narrow space environment. During the maintenance period, the cable duct cover plate here needs to be removed to lay new cables, and the cover plate can be reinstalled after the new cables are laid. In this way, the cable duct cover plate located in the core area of the generator set cannot avoid being repeatedly disassembled and installed.
[0003] However, in order to ensure the stability of the wire slot cover near the rotating part of the generator and prevent the huge wind force generated by the rotation of the generator rotor from blowing over the wire slot cover and causing damage to the equipment, the wire slot cover in the core part of the generator pit is fixed by self-tapping screws. Although this method can ensure the first sealing of the cover, a large number of screws need to be removed during disassembly, and the self-tapping holes will be damaged after disassembly. When restoring the cover, it is necessary to drill and tap again. Therefore, it is very troublesome to disassemble and reinstall the wire slot cover fastened with self-tapping screws. Utility Model Content
[0004] In order to solve the above problems existing in the prior art, the purpose of the utility model is to provide a segmented special cable tie for fixing a cable trough cover.
