Description

Technical Field

[0001] The utility model relates to the technical field of insulator installation, in particular to an insulator installation bracket and a transmission iron tower. Background Art

[0002] Wind farms use cables to lead wind turbines to nearby terminal towers, and then introduce them to booster stations and power grids through overhead lines. Cable towers refer to cables climbing from underground to the cross arm brackets of the towers. After the cables are on the towers, the three cores or three single cores of the cables are connected to the three-phase conductors A, B, and C on the towers through the terminals of the cable heads to complete the conversion between cables and overhead lines. In order to prevent the overhead cables from discharging to the towers during normal operation, insulators must be fixed to the towers to support the cables away from the towers to ensure the overvoltage safety of the cables.

[0003] The current mainstream insulators usually include horizontally connected FS composite insulators and vertically connected FZS sitting composite insulators. Each insulator is equipped with a special clamp to fix it on the tower. However, when the demand is for FS composite insulators, but after purchasing FZS sitting composite insulators, it is necessary to make a rectification plan, replace the bracket or re-purchase the insulator, which increases the cost.

[0033] It can be seen from the above scheme that the insulator mounting bracket provided by the utility model has a simple structure and is convenient and reliable to install. By clamping the bracket fixing portion 3 between the first clamping surface 100 and the second clamping surface 200, the installation process of the insulator becomes simple and quick, and the steps required for adjustment and alignment during the installation process are reduced, thereby greatly improving the installation efficiency; and this method ensures a stable connection between the insulator and the transmission tower, and can ensure that the insulator can maintain a stable installation state under various weather and load conditions, thereby reducing the safety hazards caused by loosening or displacement. The design of the mounting bracket takes into account insulators of different types and models, so that it can be widely used in a variety of insulators. This highly compatible design makes it unnecessary to replace the entire mounting bracket when replacing or upgrading the insulator, thereby reducing maintenance costs, avoiding the problem of wasting manpower and time caused by replacing different mounting brackets due to different types of insulators in the prior art, and reducing costs.
