Description

Technical Field

[0001] This utility model relates to the field of transformer frame technology, and in particular to a power transformer frame. Background Technology

[0002] A transformer is an important electrical device in a power system used to transmit and distribute electrical energy. It can change the magnitude of AC voltage according to the principle of electromagnetic induction to meet different power demands. It is mainly composed of a primary coil, a secondary coil, an iron core, and a transformer frame. The power transformer frame is the framework structure that supports the iron core of the power transformer. It is also called the transformer skeleton or transformer wire frame and is a major structural component of the transformer. It not only provides space for the copper wires in the transformer to be wound, but the metal pins in the frame also serve as supports for the winding of the copper wires. After being soldered, it is connected to the PCB board and plays a conductive role when the transformer is working.

[0003] Existing patent (application number 202421391100.7) discloses a transformer frame structure, including a top plate, winding posts, a bottom plate, and pin base components. This utility model, by providing a pin base component that protects the pins, allows for the rotatable folding rod to engage with the internally threaded connecting plate during transformer transportation and storage. Adjusting the bottom support plate, with the assistance of positioning posts, extends the plate, thus shielding and protecting the pins at the bottom of the connecting plate from damage. This improves the practicality of the transformer frame structure for safe storage. Furthermore, the foldable folding rod allows for outward folding after the support plate is retracted, reducing the space occupied by the folding rod and enhancing the convenience and practicality of the transformer frame structure.

[0004] The existing transformer frames lack adequate protection for their pins during transportation, making them susceptible to damage. Furthermore, most transformer frames are one-piece structures, which are not only inconvenient to disassemble and carry, but also difficult to replace damaged components. Utility Model Content

[0005] Therefore, it is necessary to provide a power transformer frame to address the technical problems that the pins on the transformer frame are not well protected during transportation and are easily damaged; in addition, most transformer frames are one-piece structures, which are not only inconvenient to disassemble and carry, but also inconvenient to replace damaged parts.

[0006] A power transformer frame includes a winding post. A first mounting plate is inserted and fixedly installed at the upper end of the winding post. Two No. 1 screws are installed at the middle of the left and right ends of the first mounting plate. A second mounting plate is inserted and fixedly installed at the lower end of the winding post. Two No. 2 screws are installed at the middle of the left and right ends of the second mounting plate. A support device is fixedly installed at the left and right ends of the second mounting plate.

[0007] In one embodiment, a No. 1 fixing seat is fixedly installed on the upper left and upper right parts of the winding post, and a No. 2 fixing seat is fixedly installed on the lower left and lower right parts of the winding post. Two No. 1 screw holes are opened at the right ends of the two No. 1 fixing seats and the two No. 2 fixing seats. A set of heat dissipation holes are opened at the upper front end, lower front end, upper left end, lower left end, upper rear end, lower rear end, upper right end, and lower right end of the winding post. Several winding grooves are opened on the outer surface of the winding post.

[0008] The design of several winding grooves on the winding post facilitates the winding of the device. In addition, two sets of heat dissipation holes are opened on each of the four end faces of the winding post, thereby improving the heat dissipation performance of the winding post.

[0009] In one embodiment, the first mounting plate has several protective holes at the front and rear of its upper end, and a first mounting groove at the middle of its upper end. The first mounting plate is fixedly mounted on two first fixing seats by a first screw.

[0010] Align the No. 1 mounting plate with the No. 1 mounting slot on it to the two No. 1 fixing seats on the winding column and insert it into the upper end of the winding column. Then screw the No. 1 screw into the No. 1 fixing seat to complete the installation of the No. 1 mounting plate. Similarly, align the No. 2 mounting plate with the No. 2 mounting slot on it to the No. 2 fixing seat on the winding column and insert it into the lower end of the winding column. Then screw the No. 2 screw into the No. 2 fixing seat to complete the assembly of the transformer frame. The device can be disassembled by loosening the No. 1 and No. 2 screws, which not only facilitates the disassembly and carrying of the device, but also makes it easy to replace damaged parts.

[0011] In one embodiment, the second mounting plate has two No. 2 screw holes at the front and rear of its upper end, and several pins are fixedly installed at the front and rear of its lower end. The second mounting plate has a No. 2 mounting groove in the middle of its upper end, and the second mounting plate is fixedly installed on two No. 2 mounting seats by No. 2 screws.

[0012] When transporting the device, mounting plate number two can be placed on top of mounting plate number one. At this time, the pins on mounting plate number two can be inserted into the protective holes on mounting plate number one. This not only further facilitates the transport of the device, but also protects the pins from being scratched by external objects during transport.

[0013] In one embodiment, the support device includes a support frame with a slot at the left end. No. 3 screws are installed at the front and rear of the upper end of the support frame, and anti-slip rubber pads are fixedly installed at the front and rear of the lower end of the support frame. The support frame is fixedly installed on the right end of the second mounting plate by inserting No. 3 screws.

[0014] When placing the transformer frame, the two support frames not only support the device, but also prevent the pins at the bottom of the No. 2 mounting plate from directly contacting the table or ground. In addition, the anti-slip rubber pads at the bottom of the support frames also improve the stability during placement.

[0015] In one embodiment, both the first mounting plate and the second mounting plate are square-shaped.

[0016] In one embodiment, the first screw corresponds left-right to the first screw hole on the first fixing base, and the second screw corresponds left-right to the first screw hole on the second fixing base.

[0017] In one embodiment, a plurality of the winding grooves are formed at equal intervals from top to bottom on the outer surface of the winding post.

[0018] In one embodiment, the pins are positioned vertically opposite to the protective sockets, and the protective sockets are larger than the pins.

[0019] In one embodiment, the width of the slot is the same as the width of the second mounting plate.

[0020] The aforementioned power transformer frame is assembled by aligning the first mounting slot of the first mounting plate with the two first fixing seats on the winding post and inserting it into the upper end of the winding post. Then, the first screw is screwed into the first fixing seat. Similarly, the second mounting plate is aligned with the second fixing seat on the winding post and inserted into the lower end of the winding post. Then, the second screw is screwed into the second fixing seat, thus completing the assembly of the transformer frame. The assembly can be disassembled by loosening the first and second screws, which not only facilitates disassembly and transport of the assembly but also makes it easy to replace damaged parts. Furthermore, the second mounting plate... The mounting plate is also equipped with two support frames. When the transformer frame is placed, the two support frames not only support the device, but also prevent the pins at the bottom of the second mounting plate from directly contacting the table or ground. In addition, the anti-slip rubber pads at the bottom of the support frames also improve the stability during placement. When the device is transported, the second mounting plate can be placed on top of the first mounting plate. At this time, the pins on the second mounting plate can be inserted into the protective holes on the first mounting plate. This not only further facilitates the transportation of the device, but also protects the pins from being scratched by external objects during transportation. Attached Figure Description
