Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to an oil-immersed power transformer. Background Art

[0002] An oil-immersed power transformer is a transformer that uses insulating oil as a medium. It converts high-voltage electricity into low-voltage electricity, making power transmission more efficient. The main function of an oil-immersed power transformer is to transmit electricity from a power station to users. It is also used for power needs in various industrial and commercial locations. This type of transformer has good insulation performance and stability, which can effectively reduce power loss and failure rate. In addition, oil-immersed power transformers can also be used for the storage and distribution of electric energy, and are an indispensable and important equipment in modern power systems.

[0003] For example, the patent application number of China Patent Network is: 201921186475.9. The utility model discloses an oil-immersed power transformer, which relates to the technical field of transformers. The oil-immersed power transformer comprises a transformer body, a radiator fin is fixedly installed on the front of the transformer body, a water tank is fixedly installed on the right side of the transformer body, a micro water pump is fixedly installed on the top of the water tank, and the water inlet of the micro water pump is connected to the inner cavity of the water tank through a water pipe, the bottom end of the water pipe extends to a position near the bottom of the water tank, and the water outlet of the micro water pump is connected to the inner cavity of the water tank. One end of the bent tube is connected and communicated. When water passes through the bent tube of the oil-immersed power transformer, the heat between adjacent radiators is conducted to the surface of the bent tube with a lower temperature using air as the medium, thereby promoting the cooling of the radiator. At the same time, the heat dissipation conduction mode of the radiator is further improved through the heat dissipation element, thereby ensuring that the heat accumulated between adjacent radiators is easily discharged when used for high-power transformers. The utility model has no additional shielding and protection mechanism, which may easily cause the top of the transformer to bump during transportation or hoisting, thereby causing damage to the transformer.

There are multiple and evenly distributed limiting grooves 11 on the top of the inner wall of the sliding groove 10.

[0026] refer to Figure 5 A handle 12 is fixedly connected to the outer side of the sliding rod 5 , and there are multiple handles 12 that are evenly distributed on the outer side of the sliding rod 5 .

[0027] As a technical optimization solution of the present invention, by providing the handle 12, the sliding rod 5 can be pulled to make the sliding process to the specified position more convenient and faster.

[0028] refer to Figure 3 The front and rear sides of the bottom of the fixing frame 2 are fixedly connected with reinforcement blocks 13 , and the bottom of the reinforcement block 13 is fixedly connected to the top of the transformer 1 .

During the sliding process of the sliding rod 5 near the connecting rod 16, it will not be stuck in the small limit groove 11 until each sliding rod 5 is stuck in turn according to the limit grooves 11 of different sizes, thereby shielding and protecting the space between the fixing frames 2 (the support rod 3 further supports and fixes the fixing frames 2), thereby achieving the purpose of protecting the top of the transformer 1, avoiding the situation that the traditional transformer 1 has no additional shielding and protection mechanism, and is easy to bump against the top components of the transformer 1 during transportation or lifting, causing damage to the transformer 1, thereby making it have the advantage of protecting the transformer 1.

[0037] To sum up: when the utility model is used, under the action of the fixing mechanism and the limiting mechanism, the top of the transformer 1 can be shielded and protected, avoiding the problem that the traditional transformer 1 has no additional shielding and protection mechanism, and is easy to bump into the top parts of the transformer 1 during transportation or lifting, causing damage to the transformer 1, thereby making it have the advantage of protecting the transformer 1 and solving the problem that the transformer 1 is easily bumped during lifting and transportation.
