Description

Technical Field

[0001] This utility model relates to the field of electric furnace transformer technology, specifically to a direct-connection structure for an electric furnace transformer in a submerged arc furnace. Background Technology

[0002] A direct-connection structure for an electric furnace transformer means that the primary side of the transformer is directly connected to the power supply, while the secondary side is directly connected to the electric furnace's circuitry. This structure simplifies transformer design, reduces energy loss during transmission, and provides a more stable voltage and current supply.

[0003] Common transformer direct-connection structures typically use coils to achieve voltage step-up and step-down transformations, with insulating bushings used to isolate the high-voltage and low-voltage coils, and connecting devices used to connect the transformer to other electrical equipment to ensure efficient power transmission.

[0004] Transformer direct-connection structures typically use terminal blocks for connection. However, due to the long length of the terminal block's wires, the wires are prone to tangling after installation, resulting in a messy wire configuration. Additionally, the electric furnace transformer may overheat and damage the terminal block if it operates for extended periods beyond its rated load. Furthermore, the terminal block requires numerous bolts for installation, leading to lengthy disassembly and reassembly processes and slowing down the replacement process. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a direct-connection structure for the electric furnace transformer of a submerged arc furnace, which solves the problems mentioned in the background technology, such as the easy entanglement of wires, resulting in wires being scattered, and the electric furnace transformer operating for a long time under conditions exceeding the rated load, which may cause the terminal block to overheat and be damaged. However, since the terminal block requires too many bolts for installation, it takes a long time to disassemble and assemble, reducing the speed of replacement.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a direct-connection structure for an electric furnace transformer in a submerged arc furnace, comprising:

[0009] The transformer casing has terminal blocks installed on both sides.

[0010] A fixing plate is set above the terminal block, and receiving plates are installed on both sides of the terminal block. A positioning rod is screwed between the fixing plate and the receiving plate.

[0011] A terminal block is positioned above the terminal block. Guide rods are evenly distributed on the left side of the terminal block, and adjustment blocks are fitted onto the surface of each guide rod.

[0012] A wire clamp is located at the bottom of the adjusting block. A limit clamp is provided below each wire clamp. Limit plates are installed on both sides of the wire clamp and the limit clamp. Bolts are screwed between the two limit plates.

[0013] Preferably, the surface of the guide rod is evenly provided with insertion holes, and the surface of the adjusting block is also provided with insertion holes. A pin is inserted into the inner cavity of the insertion hole. The pin is inserted through the insertion hole of the adjusting block and into the insertion hole of the guide rod, thereby fixing the adjusting block.

[0014] Preferably, each of the upper surfaces of the adjusting blocks is equipped with a slider, and each of the terminal blocks is welded with a slide rail at a position corresponding to the slider. The slider is inserted into the slide rail to limit the adjustment block, so that the adjusting block can move stably along the surface of the guide rod.

[0015] Preferably, mounting blocks are installed on both sides of the fixing plate, and mounting grooves are opened on the surface of the receiving plate. The mounting blocks are embedded in the inner cavity of the mounting grooves, which can limit the fixing plate and prevent the fixing plate from shifting when fixing the terminal block.

[0016] Preferably, the upper surface of the terminal block is evenly provided with wiring grooves, and pressure plates are installed at the bottom of the fixing plate at positions corresponding to the wiring grooves. When the terminal block is inserted into the wiring groove, the pressure plate can penetrate the wiring groove and contact the upper surface of the terminal block, thereby fixing the terminal block more firmly.

[0017] Beneficial effects

[0018] Compared with the prior art, this utility model provides a direct-connection structure for the electric furnace transformer of a submerged arc furnace, which has the following advantages:

[0019] 1. The electric furnace transformer direct-connection structure of this submerged arc furnace can move the limit clamp close to the surface of the wire clamp by rotating the bolt, thereby limiting the wire. By moving the adjusting block along the surface of the guide rod, the wire can be straightened, thus effectively preventing the wires from contacting each other and getting tangled.

[0020] 2. The electric furnace transformer direct-connection structure of this submerged arc furnace allows the fixed plate to be pressed by rotating the positioning rod. The fixed plate, in conjunction with the terminal block, can position the terminal block. The terminal block can be disassembled simply by rotating the positioning rod to loosen it, thus facilitating the disassembly and assembly of the terminal block and improving the speed of terminal block replacement.

Figure 6 Adjusting blocks 8 are fitted onto the surface of each guide rod 7;

[0032] The wire clamp 9 is located at the bottom of the adjusting block 8. The wire clamp 9 is provided with a limit clamp 10 below it. The wire clamp 9 and the limit clamp 10 are both equipped with limit plates 11 on both sides. The two limit plates 11 are screwed together with bolts 12.

[0033] The rotating positioning rod 5 can press the fixing plate 3. The fixing plate 3 and the terminal block 2 can position the terminal block 6. The terminal block 6 can be disassembled by simply rotating the positioning rod 5 to loosen it, which facilitates the disassembly and assembly of the terminal block 6 and improves the replacement speed of the terminal block 6.

[0034] When the wire is inserted between the wire clamp 9 and the limiting clamp 10, rotating the bolt 12 can move the limiting clamp 10 closer to the surface of the wire clamp 9, thereby limiting the wire. By moving the adjusting block 8 along the surface of the guide rod 7, the wire can be straightened, thus effectively preventing the wires from contacting each other and getting tangled.

[0035] The surface of the guide rod 7 is evenly provided with insertion holes 13, and the surface of the adjusting block 8 is also provided with insertion holes 13. A pin 14 is inserted into the inner cavity of the insertion hole 13. The pin 14 is inserted through the insertion hole 13 of the adjusting block 8 and into the insertion hole 13 of the guide rod 7, so as to fix the adjusting block 8.

[0036] The upper surface of the adjusting block 8 is equipped with a slider 15. The terminal block 6 is welded with a slide rail 16 at the corresponding position of the slider 15. The slider 15 is inserted into the slide rail 16, which can limit the adjustment block 8 so that the adjustment block 8 can move stably along the surface of the guide rod 7.

[0037] Please see Figure 5 Mounting blocks 17 are installed on both sides of the fixing plate 3. Please refer to [link / reference]. Figure 3 The surface of the receiving plate 4 is provided with mounting grooves 18. The mounting block 17 is embedded in the inner cavity of the mounting groove 18, which can limit the position of the fixing plate 3 so that the fixing plate 3 will not shift when fixing the terminal block 6.

[0038] The upper surface of the junction box 2 is evenly provided with wiring grooves 19. Please refer to [link / reference]. Figure 5 Pressure plates 20 are installed at the bottom of the fixing plate 3 and at the corresponding positions of the wiring groove 19. The terminal block 6 is inserted into the wiring groove 19. The pressure plates 20 can penetrate the wiring groove 19 and contact the upper surface of the terminal block 6, thereby fixing the terminal block 6 more firmly.

[0039] The working process of this device is as follows: First, the wire is inserted between the wire clamp 9 and the limiting clamp 10. Rotating the bolt 12 can drive the limiting clamp 10 to approach the surface of the wire clamp 9, thereby limiting the wire. By moving the adjusting block 8 along the surface of the guide rod 7, the wire can be straightened, thus effectively preventing the wires from contacting each other and getting tangled. Then, the pin 14 passes through the insertion hole 13 of the adjusting block 8 and is inserted into the insertion hole 13 of the guide rod 7, thereby fixing the adjusting block 8 and positioning the wire. Finally, rotating the positioning rod 5 can squeeze the fixing plate 3. The pressure plate 20 can pass through the wiring groove 19 and contact the upper surface of the terminal block 6, thereby fixing the terminal block 6 more firmly. Simply rotate the positioning rod 5 to loosen it, and the terminal block 6 can be disassembled, thus facilitating the disassembly and assembly of the terminal block 6 and improving the replacement speed of the terminal block 6.
