Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to a direct current converter transformer. Background Art

[0002] The converter transformer refers to the power transformer connected between the converter bridge and the AC system. The converter transformer is used to connect the converter bridge to the AC bus and provide a three-phase commutation voltage with an ungrounded neutral point for the converter bridge. The converter transformer and the converter bridge are the main components of the converter unit. The converter transformer is a critical equipment in the ultra-high voltage direct current transmission project and is the core equipment for the interface between the rectifier and inverter in the AC and DC transmission systems. Its investment and safe operation are the key and important guarantee for the project to achieve power generation benefits. When the DC converter transformer is running at high power for a long time, its internal temperature will rise rapidly, resulting in overheating, which will easily accelerate the aging of internal components in the long run.

[0003] The utility model patent with the publication number CN212461301U discloses a DC converter transformer, including a waterproof shell, a transformer body is fixedly arranged in the waterproof shell, two vertical side walls opposite to each other on the left and right sides of the waterproof shell are provided with a plurality of downwardly inclined heat dissipation holes and a shielding mechanism connected to shield the heat dissipation holes to achieve a waterproof effect, a plurality of inclined water inlet holes are evenly provided on the upper end of the waterproof shell, a water pipe whose upper end is connected to the lower end of the water inlet hole is fixedly connected between the inner walls on the upper and lower sides of the waterproof shell, and a water outlet hole connected to the water pipe is provided at the lower end of the waterproof shell. The utility model has good protection for the transformer body and is easy to use.

[0004] However, the above patent has the following shortcomings: the cooling method is relatively dependent on the external environment to drive the active fan blades with wind power, which is relatively random, resulting in insufficient stability and reliability, and the actual heat dissipation effect is not ideal. Therefore, this heat dissipation design is difficult to apply to DC converter transformers with higher power. Summary of the invention

[0005] In order to solve the above technical problems existing in the existing transformers, the present invention provides a DC converter transformer with good stability and ideal heat dissipation effect.

[0006] The technical solution of the present invention is as follows: a DC converter transformer comprises a mounting base and a transformer shell fixedly mounted on the mounting base, characterized in that: the interior of the mounting base is arranged as a cavity-shaped structure, and a blast assembly is arranged inside the mounting base, the inner bottom of the transformer shell is fixedly mounted with the inner body of the transformer, and a flow guide assembly is arranged inside the transformer shell, the transformer shell is provided with a cooling ring cavity, and a spoiler assembly is arranged inside the cooling ring cavity, an active cooling assembly is arranged on the outer side of the transformer shell, and an air distribution assembly is arranged on the top of the transformer shell; the flow guide assembly comprises a plurality of spiral flow guide wall rods fixedly mounted on the circumferential inner wall of the transformer shell, and the spiral flow guide wall rods are provided with cavity openings, wherein two of the spiral flow guide wall rods are clamped with wiring terminals in the cavity openings, and one end of the two wiring terminals is electrically connected to the transformer shell, the position of the wiring terminal close to the spiral flow guide wall rod is arranged as a clamping terminal, and the clamping end is clamped with the inner wall of the cavity opening, and the flow guide assembly also comprises an air guide plate rotatably connected to the bottom of the transformer shell. The present invention utilizes the set guide component.

While ensuring full contact and heat exchange with the inner wall of the transformer housing, the hot air inside the transformer housing can be discharged more quickly to achieve rapid cooling. The present invention utilizes the cavity provided on the spiral guide wall rod. On the one hand, it can improve the guiding effect on the air flow. On the other hand, the cavity can clamp and arrange the clamping end on the wiring terminal. The set spiral guide wall rod can perform heat exchange with the cooling ring cavity, so that when the active cooling component is running, the spiral guide wall rod itself can be quickly cooled. At the same time, the clamping end is wrapped with the help of the set cavity, which is beneficial to quickly cooling the wiring terminal.
