Description

Technical Field

[0001] This utility model relates to the field of power distribution transformer technology, specifically a three-dimensional wound core low-loss intelligent power distribution transformer. Background Technology

[0002] Distribution transformers are static electrical devices in power systems used to convert high-voltage electrical energy into low-voltage electrical energy (and in a few cases, to step up voltage). They are mainly used at the terminal of the distribution network to provide standard-compliant low-voltage electrical energy to various users and are key equipment for power transmission and distribution.

[0003] The three-dimensional wound core low-loss intelligent distribution transformer is a type of distribution transformer that integrates a new core structure, low-loss technology, and intelligent functions. By winding the core into a three-dimensional shape (usually a three-phase five-limb type), it reduces magnetic resistance and losses at the core joints. At the same time, by optimizing the core material (such as using high magnetic induction silicon steel sheets) and reducing no-load and load losses, it achieves high efficiency and energy saving, and improves the magnetic permeability and structural stability of the core. In addition, by equipping it with sensors, data acquisition and communication modules, it can monitor operating parameters such as voltage, current, temperature, and loss in real time, and supports remote data transmission and status diagnosis, thereby facilitating refined operation and maintenance and intelligent power grid management.

[0004] Traditional three-dimensional wound core distribution transformers are typically installed by directly connecting and fixing them with bolts. This makes it difficult for operators to accurately control the relative position of the transformer and the base when lifting the transformer with a crane, due to the transformer's own weight and the tendency to sway during the lifting process. This results in repeated adjustments to the lifting position when aligning the bolt holes, which not only prolongs the installation time but also increases the safety hazards during the lifting process. To further improve the efficiency of distribution transformer installation, a three-dimensional wound core low-loss intelligent distribution transformer is now offered, which can eliminate the drawbacks of the existing device.

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0040] In one embodiment, such as Figures 1-5 As shown, the three-dimensional wound core low-loss intelligent power distribution transformer includes a transformer body 1. A docking base plate 4 is fixedly connected to the bottom end of the transformer body 1. A fixed base 3 is provided on the lower surface of the docking base plate 4. Multiple heat dissipation components 5 are installed equidistantly on the outer wall of the transformer body 1. A docking mechanism is provided on the fixed base 3 for convenient docking and fixing of the fixed base 3 and the docking base plate 4.

[0041] The docking mechanism includes: a docking plate 203 fixedly connected to the top of the fixed base 3, the outer wall of the top of the docking plate 203 is frustum-shaped, a docking slot for sliding the docking plate 203 is provided at the docking base 4 where it meets the docking plate 203, and multiple balls are circumferentially equidistantly connected to the top of the docking plate 203, and the multiple balls are in contact with the inner wall of the docking slot.

[0042] In this embodiment, during use, the transformer body 1 is hoisted to the top of the fixed base 3 by a crane and lowered vertically, so that the docking base plate 4 can dock with the fixed base 3 under the drive of the transformer body 1. During this process, the docking base plate 4 is lowered to fit onto the outer wall of the docking insert plate 203. At this time, multiple heat dissipation components 5 are located above multiple fixed plates 204 respectively, until the docking base plate 4 contacts multiple balls, so as to realize convenient docking between the fixed base 3 and the docking base plate 4.

[0043] Then, the transformer body 1 is pushed to rotate around the docking plate 203 as the axis. At this time, the docking base plate 4 is driven by the transformer body 1 and rotates synchronously through the ball bearings. At the same time, the docking mechanism can easily engage, position and lock the docking base plate 4, thereby effectively preventing the transformer body 1 from rotating during use, so as to further improve the efficiency of installing the transformer body 1.

[0044] In one embodiment, such as Figures 1-5 As shown, the docking mechanism also includes a positioning component mounted on the fixed base 3;

[0045] The positioning assembly includes: multiple limiting baffles 2016 circumferentially equidistantly slidably connected inside the fixed base 3; the multiple limiting baffles 2016 and multiple heat dissipation components 5 are interleaved; each of the multiple limiting baffles 2016 has a fixedly connected positioning block 202 at its top; the outer wall of the top of the positioning block 202 is hemispherical; the positioning block 202 penetrates through the fixed base 3 to the interior of the docking base plate 4; each of the multiple limiting baffles 2016 has a fixedly connected limiting slide rod 2015 at its bottom; the positioning block 202 and the limiting slide rod 2015 are slidably connected to the fixed base 3; a spring 2014 is sleeved on the outer wall of the limiting slide rod 2015; one end of the spring 2014 contacts the outer wall of the limiting baffle 2016; and the other end of the spring 2014 contacts the inner wall of the fixed base 3.

[0050] A connecting shaft 208 is rotatably connected inside the fixed base 3. The connecting shaft 208 is located below the docking plate 203. A second gear 207 is fixedly connected to the top of the connecting shaft 208, and a first gear 206 is fixedly connected to the bottom of the connecting shaft 208. Both the first gear 206 and the second gear 207 are rotatably connected to the fixed base 3.

[0051] A movable component is provided on the first gear 206;

[0052] A second rotating component is provided on the fixed base 3;

[0053] The moving component includes: a plurality of first racks 205 circumferentially and equidistantly meshed on the outer wall of the first gear 206, the plurality of first racks 205 being slidably connected to the fixed base 3, the plurality of first racks 205 being located below the plurality of limiting baffles 2016, the first racks 205 being in contact with the lower surface of the limiting slide rods 2015, and through the mutual cooperation of the first rotating component and the moving component, the limiting slide rods 2015 at the bottom of the plurality of limiting baffles 2016 can be blocked synchronously, thereby synchronously fixing the plurality of limiting baffles 2016;

[0054] In one embodiment, such as Figures 1-4 As shown, the second rotating assembly includes: a turntable 2012 disposed outside one end of the fixed base 3, a handle being eccentrically fixed to the end of the turntable 2012 away from the fixed base 3, a transmission rod 2011 being fixedly connected to one end of the turntable 2012, the transmission rod 2011 penetrating into the interior of the fixed base 3, a lead screw 209 being fixedly connected to the end of the transmission rod 2011 away from the turntable 2012, the lead screw 209 being located outside the second gear 207, and both the lead screw 209 and the transmission rod 2011 being rotatably connected to the fixed base 3;

[0055] A push assembly is provided on the lead screw 209;

[0056] The turntable 2012 is equipped with a locking mechanism;

[0057] The pushing component is a second rack 2010 sleeved on the outer wall of the lead screw 209. The second rack 2010 is slidably connected to the fixed base 3, meshing with the second gear 207, and threadedly connected to the lead screw 209. Through the mutual cooperation of the second rotating component and the pushing component, the second gear 207 can be driven to rotate.

[0058] In one embodiment, such as Figures 1-4As shown, the locking component is a knurled bolt 2013 eccentrically positioned at the end of the turntable 2012 away from the fixed base 3. The knurled bolt 2013 penetrates the turntable 2012 into the interior of the fixed base 3 and is threadedly connected to the turntable 2012. The turntable 2012 can be easily locked and fixed by the knurled bolt 2013.

[0059] The above embodiments disclose a three-dimensional wound core low-loss intelligent power distribution transformer. In use, the transformer body 1 is hoisted to the top of the fixed base 3 by a crane and lowered vertically. This allows the docking base plate 4 to dock with the fixed base 3 under the action of the transformer body 1. During this process, the docking base plate 4 is lowered to fit onto the outer wall of the docking plug plate 203. At this time, multiple heat dissipation components 5 are located above multiple fixed plates 204, until the docking base plate 4 contacts multiple balls. This enables convenient docking between the fixed base 3 and the docking base plate 4.

[0060] Then, the transformer body 1 is driven to rotate around the docking plate 203 as the axis. At this time, the docking base plate 4 rotates synchronously through the ball bearings under the drive of the transformer body 1. When the docking base plate 4 contacts the outer wall of the multiple fixed plates 204, the docking base plate 4 slides along the outer wall of the fixed plate 204 and engages with the outer wall of the fixed block 201 through the limiting groove. At the same time, the positioning block 202 is pressed by the docking base plate 4 and pushes the limiting slide rod 2015 along the inner wall of the fixed base 3 through the limiting baffle 2016. At this time, the limiting baffle 2016 retracts through the moving compression spring 2014. When the fixed block 201 contacts the inner wall of one end of the limiting groove, the spring 2014 pushes the limiting baffle 2016 to reset by rebounding. In this way, the positioning block 202 can be inserted into the interior of the docking base plate 4, so that the docking base plate 4 can be easily engaged and positioned.

[0061] Then, the turntable 2012 is rotated by the handle. At this time, the lead screw 209 rotates under the drive of the turntable 2012 via the transmission rod 2011. Simultaneously, the second rack 2010 rotates under the drive of the lead screw 209 via the thread, and drives the second gear 207 to rotate. At this time, the first gear 206 rotates under the drive of the second gear 207 via the connecting shaft 208, and drives multiple first racks 205 to move until the multiple first racks 205 move below the multiple limit baffles 2016 and contact the lower surface of the limit slide rod 2015. This can limit and block the limit slide rod 2015. Then, the knurled bolt 2013 is inserted into the interior of the fixed base 3 to limit and lock the turntable 2012, thereby effectively preventing the transformer body 1 from rotating during use, so as to further improve the installation efficiency of the transformer body 1.

[0062] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
