Embodiment Construction

[0012] The following examples illustrate the invention in detail. Various raw materials and various equipments used in the present invention are conventional commercially available products, and can be directly obtained through market purchase.

[0013] See attached figure 1 , the structure of a specific embodiment of the present invention includes a pad 1 that is arranged in the transformer and floats on the surface of the transformer oil. Hole 3, the through hole 3 to one side of the pad 1 is provided with a set opening 4 connected by a snap button, and one side of the pad 1 is also provided with a magnet 2 adsorbed on the side wall of the transformer . The snap button described in the present embodiment adopts nylon buckle, and the nylon buckle is convenient for sticking and dismantling of the suit opening.

[0014] The side of the pad 1 is also provided with buoys 5 . The setting of the buoy makes the pad float on the surface of the transformer oil on the one hand, and...

Abstract

The invention discloses a falling object prevention device used for mounting a low-voltage sleeve of a transformer. The structure comprises a cloth liner which is arranged in the transformer and is floated on the surface of transformer oil, wherein the cloth liner is provided with a through hole with the shape and position which correspond to the low-voltage sleeve; a sleeve opening which is connected by a snap fastener is formed in one side edge from the through hole to the cloth liner; a magnet which is adsorbed on the side wall of the transformer is further arranged at one side edge of the cloth liner. With the adoption of the falling object prevention device, a safe region is formed above the transformer oil so that the mounting work of a sleeve is easy and rapid; on one hand, a falling object can be effectively prevented from falling into a transformer body, and on the other hand, the psychological burden of installation workers is reduced and the installation workers can invest more vigor into connection work, so that the smooth proceeding of the installation work of the transformer is effectively guaranteed.

Description

technical field [0001] The invention relates to a protective device for installing a transformer, in particular to an anti-falling object device for installing a low-voltage bushing of a transformer. Background technique [0002] When installing the main transformer of the substation, because the manufacturer considered the height limit of the bridge tunnel, the 10KV low-voltage bushing of the 110kV transformer transported to the site was not installed with the transformer, and the bushing was assembled with the transformer at the construction site. Usually, after the transformer has been evacuated and filled with oil, the low-voltage bushing terminal and the low-voltage winding have not been connected, and the low-voltage bushing and low-voltage winding need to be connected, but because the transformer is filled with oil at this time, and The three reserved holes for installing low-voltage bushing wiring are very small, and each hole can only allow one arm to enter. The ins...
