It is an important link in the power supply system and can ensure a stable supply and reasonable distribution of electrical energy. The substation safety belt suspension device is a safety device specially designed for high-altitude operations in substations. The ceiling of the substation can be supported by the suspension device, and then the safety belts are tied to the maintenance personnel to allow the substation to be repaired at high altitude.

[0026] Working principle: The substation is a place in the power system where voltage and current are transformed, concentrated and distributed. It mainly connects power grids of various voltage levels through transformers. Its main task is to receive electric energy, transform voltage and distribute electric energy. It is an important link in the power supply system and can ensure the stable supply and reasonable distribution of electric energy. The substation safety belt suspension device is a safety device specially designed for high-altitude operations in substations. The ceiling of the substation can be supported by the suspension device, and then the safety belts are tied to the maintenance personnel, so that the substation can be repaired at high altitude. The suspension frame 1 is mainly used for high-altitude operations and is locked with the height of the substation. The suspension frame A locking pin is installed between the body 1, and the locking pin and the suspension frame body 1 wrap the ceiling, that is, the suspension frame body 1 is firmly installed above the ceiling, the hook 2 is linked to the safety belt, and a plurality of first chains 9 are linked to each other, and the two sides of the suspension frame body 1 can be further limited and supported. The first chains 9 are respectively arranged at the middle position of the two U-shaped plates 8. The auxiliary rod 5, the limiting ring 6, the U-shaped plate 8 and the first chain 9 are all made of steel materials, which have high hardness and are not easy to deform. One end of two of the auxiliary rods 5 is respectively fixed to the two sides of the suspension frame body 1, and one end of the other two auxiliary rods 5 is respectively supported by the movable sleeve 4, and appears on the top of the suspension frame body 1. When the suspension frame 1 breaks, a crack will appear in the middle of the suspension frame 1.

The first extension rib 11 and the second extension rib 13 are connected by the second spring 12 When the second spring 12 is not under stress, the coils are tightly fitted together. When the second chain 14 is squeezed against the ceiling, the two second springs 12 will extend and stretch when stressed, so that the second chain 14 maintains stability and balance. The auxiliary block 10 is fixedly connected to the interior of the suspension frame 1, and multiple second chains 14 are distributed inside the suspension frame 1, which enhances the practicability of the suspension frame 1.
