Technical Field

[0001] The utility model relates to the technical field of transformers, and more specifically, the utility model relates to a top-mounted transformer. Background Art

[0002] A top-mounted transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, the secondary coil and the iron core. Its main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. Existing transformers basically use transformer oil and heat sink fins to dissipate heat from the transformer. However, the traditional air-cooling method is to place heat sink fins on the surface of the transformer box, and the air-cooling effect is not ideal.

[0003] The utility model patent with patent application publication number CN202223597912.0 discloses a transformer, which includes a transformer body. The advantage of this structure is that it can accelerate the flow rate of the circulation channel of the heat dissipation fins, effectively improve the heat dissipation effect of the transformer, and solve the problem of weak heat dissipation effect in the prior art.

[0004] However, in actual use, since the transformer is directly placed inside the cabinet, the transformer needs to be manually moved out of the cabinet for maintenance during maintenance. The transformer itself is heavy and large in size, which makes it inconvenient to move the transformer, thus easily affecting the work efficiency during transformer maintenance. Utility Model Content

The above-mentioned technical solution is adopted to facilitate the movement of the mounting seat, so that the transformer can be easily repaired.

[0007] Preferably, a first L-shaped limit block is fixedly arranged at an outer position corresponding to the second L-shaped block at the bottom of the cabinet inner cavity, and the first L-shaped limit block and the second L-shaped block can be movably connected. The above technical solution is adopted to facilitate the limitation of the mounting seat and effectively prevent the mounting seat from falling off the cabinet.

[0008] Preferably, the limit assembly includes a fixing plate fixedly arranged on the top of the fixing seat, a second screw is threadedly sleeved in the inner cavity of the fixing plate, two guide rods are movably sleeved inside the fixing plate, limit plates are arranged on opposite sides of the two fixing plates, the surface of the limit plate is arranged in a wavy shape, one end of the second screw and the guide rod are fixedly connected to the surface of the limit plate, and a handle is fixedly arranged on the other end of the second screw. The above technical solution is adopted to facilitate the positioning of the transformer.

[0009] Preferably, first filters are provided on both sides of the cabinet surface; waterproof covers are provided outside the two first filters, the waterproof covers are fixedly provided on the cabinet surface, and heat dissipation fins are provided at the bottom of the waterproof covers. The above technical solution is adopted to facilitate air circulation inside the cabinet and reduce the entry of dust.

[0010] The technical effects and advantages of this utility model are:

[0011] By setting up auxiliary components, when the transformer needs to be repaired, the motor is used to drive the mounting seat to move in parallel, which can reduce labor costs when the transformer is repaired, and the operation is simple. At the same time, multiple rollers are used to disperse the force points of the mounting seat during movement, which can improve the stability of the transformer movement during maintenance. The second L-shaped block and the first L-shaped limit block are engaged to enable the mounting seat to drive the transformer to move to the edge of the cabinet, which can prevent the transformer from falling off the cabinet, thereby improving the protection effect and safety of the device.

[0012] By setting a limit assembly, turning the handle can cause the second screw to rotate so as to adjust the distance between the limit plate and the transformer, and make the limit plate contact the surface of the transformer. Since the surface of the limit plate is set to a wave shape, the friction between the limit plate and the transformer can be effectively increased, which can facilitate the positioning of the transformer and improve the efficiency of the transformer during installation.
