A horizontal conjugate water-cooled reactor

Abstract

This utility model belongs to the field of reactors, and in particular to a horizontal conjugate water-cooled reactor. It addresses the problems of existing methods where, in practical use, a cooling box or cooling pipe is usually fixed to the coil for cooling. However, this direct fixing method cannot adjust the fit between the cooling box and the coil according to actual conditions to achieve a good cooling effect. Furthermore, the upper yoke core cannot be positioned during installation and requires repeated movement to align with the bolt holes, which is inconvenient. The proposed solution includes a lower yoke core, an upper yoke core, and a cooling box for cooling. The lower yoke core has first fixing brackets on both sides, and the upper yoke core can be positioned via positioning slots. This avoids the inconvenience of repeatedly moving the upper yoke core to align with the bolt holes in traditional installation methods, greatly improving installation efficiency. The fit between the cooling box and the coil can be flexibly adjusted via an adjustment mechanism.

Description

Technical Field

[0001] This utility model relates to the field of reactor technology, and in particular to a horizontal conjugate water-cooled reactor. Background Technology

[0002] A reactor is an electrical component in a power system, primarily used to reduce capacitive loads on equipment during operation, thereby improving equipment efficiency and power quality. A reactor typically consists of components such as a coil and an iron core. Alternating current flows through the coil, creating an electromagnetic field that causes a phase shift in the current.

[0003] In practical use, cooling boxes or cooling pipes are usually fixed to the coil for cooling. However, the direct fixing method cannot adjust the fit between the cooling box and the coil according to the actual situation to achieve a good cooling effect. At the same time, the yoke core cannot be positioned when it is installed, and it needs to be moved back and forth to align with the bolt holes, which is inconvenient. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing technologies where, in actual use, the cooling box or cooling pipe is usually fixed at the coil position for cooling. However, the direct fixing method cannot adjust the fit between the cooling box and the coil according to the actual situation to achieve a good cooling effect. At the same time, the yoke core cannot be positioned and needs to be moved back and forth to align with the bolt holes, which is inconvenient. Therefore, a horizontal conjugate water-cooled reactor is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A horizontal conjugate water-cooled reactor includes a lower yoke core, an upper yoke core, and a cooling box for cooling. The lower yoke core has a first fixing frame on both sides. Both the first fixing frame and the lower yoke core have through holes. A single first bolt passes through the through holes of both the first fixing frame and the lower yoke core. Three-phase insulating tabs are fitted onto both ends of the first bolt. One end of the first bolt is threaded with a first nut for fixing the first fixing frame, the lower yoke core, and the three-phase insulating tabs together. A single coil is fitted onto two adjacent three-phase insulating tabs. A silicon steel block is inserted into the coil. The upper yoke core is placed on top of the three coils and contacts the silicon steel block. An adjustment mechanism is provided on one side of the first fixing frame, which allows the cooling box to be aligned with the coil.

[0006] In one possible design, the adjusting mechanism includes a connecting frame and a threaded rod. The connecting frame is H-shaped, and its bottom end is welded to the top of one side of a first fixed frame. A nut for use with the threaded rod is embedded in one side of the connecting frame, and the threaded rod is threadedly connected to the nut. A bearing is fixedly installed on one side of the cooling box, and one end of the threaded rod is fixedly connected to the inner wall of the inner ring of the bearing. A knob for easy rotation is fixedly installed on one end of the threaded rod. A first pipe for connecting to an external cold water pipe and a second pipe for discharge are fixedly installed on both sides of the cooling box, and flanges are welded to both the first and second pipes.

[0007] In one possible design, two positioning slots are provided on both sides of the upper yoke core for positioning the upper yoke core, and four three-phase insulating pull tabs are respectively located in the positioning slots.

[0008] In one possible design, the connecting frame has two circular holes, and a guide rod for guiding the cooling box is slidably connected to the inner wall of the circular holes. One end of the guide rod is fixedly connected to one side of the cooling box.

[0009] In one possible design, both sides of the connecting frame are provided with screws for abutting the guide rod to prevent the threaded rod from loosening. Both sides of the connecting frame are provided with threaded holes for use with the screws. The screws are threadedly connected to the threaded holes, and one end of the screw abuts against the guide rod.

[0010] In one possible design, a second fixing bracket is provided on both sides of the upper yoke core. A second through hole is provided on both the second fixing bracket and the upper yoke core. The same second bolt is inserted into the through hole of the second fixing bracket and the upper yoke core. The top end of the three-phase insulating pull piece is sleeved on the second bolt. One end of the second bolt is threaded with a second nut for fixing the second fixing bracket, the upper yoke core and the three-phase insulating pull piece together. Two insertion holes are provided on one of the second fixing brackets. The top end of the connecting bracket is inserted into the two insertion holes.

[0011] In this application, during use, the lower yoke core is placed in a suitable working position, and the three-phase insulating pull tabs are placed on both sides of the lower yoke core. The first fixing frame is placed on one side of the three-phase insulating pull tabs of the lower yoke core, aligning the holes on the first fixing frame, the three-phase insulating pull tabs, and the through holes on the lower yoke core. The first bolt is passed through these through holes, and then the first nut is screwed onto one end of the first bolt. By tightening the first nut, the first fixing frame, the lower yoke core, and the three-phase insulating pull tabs are securely fixed together. The coil is then looped onto two adjacent three-phase insulating pull tabs. Insert silicon steel blocks into the coils, place the upper yoke core on top of the three coils, ensuring the upper yoke core is in contact with the silicon steel blocks. During placement, align the positioning groove of the upper yoke core with the three-phase insulating pull tabs (then place it so that the four three-phase insulating pull tabs are located in the four positioning grooves). Position the upper yoke core, install the second fixing brackets on both sides of the upper yoke core, align the holes at the top of the second fixing brackets and the three-phase insulating pull tabs with the second through holes on the upper yoke core, and simultaneously align the insertion hole of one of the second fixing brackets with the top of the connecting bracket. Insert the top end into the insertion hole of the second fixing bracket, pass the second bolt through these holes, and screw the second nut onto one end of the second bolt to fix the second fixing bracket, the upper yoke core, and the three-phase insulating pull plate together. Turn the knob on the threaded rod. As the threaded rod rotates, the cooling box will move under the action of the threaded drive. During the movement, the guide rods on both sides of the cooling box will slide in the round holes on the connecting bracket to guide and ensure that the cooling box can move smoothly until one side of the cooling box is in contact with the coil. After the cooling box is adjusted to the appropriate position, screw the screws into the threaded holes on both sides of the connecting bracket so that one end of the screw abuts against the guide rod. This method can prevent the threaded rod from loosening and ensure the stability of the cooling box position. Connect the first and second pipes on both sides of the cooling box to the external cold water pipe through welded flanges. In use, the external cold water enters the cooling box through the first pipe. The temperature of the cooling box is transferred to the coil for water cooling. The cooling box is made of a thermally conductive metal material, such as copper or brass. The water entering the cooling box is discharged through the second pipe.

[0012] The beneficial effects of this utility model are as follows: In this utility model, the horizontal conjugate water-cooled reactor uses positioning slots on both sides of the upper yoke core. When installing the upper yoke core, the positioning slots only need to be aligned with the three-phase insulating pull tabs, so that the four three-phase insulating pull tabs are located in the four positioning slots. This allows for quick and accurate positioning of the upper yoke core, avoiding the inconvenience of moving the upper yoke core back and forth to align with the bolt holes in the traditional installation method, and greatly improving installation efficiency. In this utility model, the horizontal conjugate water-cooled reactor allows the position of the cooling box to be adjusted according to actual conditions through the setting of the adjustment mechanism. By turning the knob on the threaded rod, the cooling box can be moved smoothly under the action of thread transmission until one side of it is in contact with the coil. In this way, the degree of contact between the cooling box and the coil can be flexibly adjusted according to different heat dissipation requirements, so as to achieve a good cooling effect and improve the heat dissipation performance of the reactor. In this invention, the upper yoke core can be positioned by the positioning groove, avoiding the inconvenience of having to move the upper yoke core back and forth to align with the bolt holes in the traditional installation method, which greatly improves the installation efficiency. The fit between the cooling box and the coil can be flexibly adjusted by the adjustment mechanism. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] In one embodiment: Refer to Figure 1-4 A reactor, used in the field of reactors, comprises: a lower yoke core 1, an upper yoke core 4, a cooling box 6, a first fixing frame 2, a second fixing frame 5, three-phase insulating pull tabs 13, a coil 3, a silicon steel block 11, and an adjusting mechanism, etc. The lower yoke core 1 is placed stably in a pre-determined installation position, ensuring its surface is flat and free of debris.

[0017] Pick up the first fixing bracket 2 and place it on both sides of the lower yoke core 1, carefully aligning the through holes on the first fixing bracket 2 with those on the lower yoke core 1. Select a first bolt of appropriate size and pass it through the through holes of the first fixing bracket 2 and the lower yoke core 1 in sequence. Attach three-phase insulating pull tabs 13 to both ends of the first bolt, ensuring the accurate positioning of the three-phase insulating pull tabs 13 to guarantee their proper insulation and fixing functions.

[0018] Using appropriate tools, such as a wrench, screw the first nut onto one end of the first bolt and tighten it gradually to secure the first fixing frame 2, the lower yoke core 1, and the three-phase insulating pull piece 13 together to form a stable lower yoke structure.

[0019] Pick up coil 3 and carefully slip it onto the two adjacent three-phase insulating tabs 13. During this process, ensure that coil 3 is installed accurately, without any misalignment or jamming. Insert the silicon steel block 11 into coil 3, ensuring a tight fit between the silicon steel block 11 and coil 3. The function of the silicon steel block 11 is to enhance the electromagnetic properties of coil 3 and improve the reactor's operating efficiency.

[0020] Pick up the upper yoke core 4 and slowly place it on top of the three coils 3. During placement, align the positioning slots 12 on both sides of the upper yoke core 4 with the three-phase insulating pull tabs 13, ensuring that the four three-phase insulating pull tabs 13 are accurately positioned within the positioning slots 12. This method allows for quick and accurate positioning of the upper yoke core 4, avoiding deviations during installation. Ensure that the upper yoke core 4 is in full contact with the silicon steel block 11 to guarantee good electromagnetic conduction performance.

[0021] Place the second fixing bracket 5 on both sides of the upper yoke core 4, aligning the second through holes on the second fixing bracket 5 and the upper yoke core 4. Select a second bolt of appropriate size, pass it through the second through holes on the second fixing bracket 5 and the upper yoke core 4, and simultaneously place the top end of the three-phase insulating pull tab 13 onto the second bolt.

[0022] Use a wrench to screw the second nut onto one end of the second bolt and tighten it to fix the second fixing bracket 5, the upper yoke core 4, and the three-phase insulating pull plate 13 together, thereby enhancing the stability of the entire reactor structure.

[0023] The bottom end of the H-shaped connecting frame 7 is welded to the top side of one of the first fixing frames 2. During the welding process, the welding quality must be ensured to ensure that the connecting frame 7 is firmly connected to the first fixing frame 2 and that the connecting frame 7 remains vertical.

[0024] A nut that mates with the threaded rod 8 is embedded in one side of the connecting bracket 7 to ensure a secure installation. The threaded rod 8 is then threaded into the nut to ensure a tight connection without any loosening.

[0025] A bearing is fixedly installed on one side of the cooling box 6, and one end of the threaded rod 8 is fixedly connected to the inner wall of the bearing's inner ring, allowing the threaded rod 8 to rotate freely around its own axis. A knob for easy rotation is fixedly installed at the other end of the threaded rod 8 to facilitate subsequent adjustment of the position of the cooling box 6.

[0026] Two round holes are made on the connecting frame 7. One end of the guide rod 9 is fixedly connected to one side of the cooling box 6. Then, the other end of the guide rod 9 is inserted into the round hole on the connecting frame 7 so that the guide rod 9 can slide in the round hole and guide the cooling box 6.

[0027] Threaded holes for use with screws 10 are made on both sides of the connecting bracket 7, and screws 10 are threaded into the threaded holes. After the position of the cooling box 6 is adjusted, screws 10 are tightened so that one end of screw 10 abuts against the guide rod 9 to prevent the threaded rod 8 from loosening and to ensure the stability of the position of the cooling box 6.

[0028] Two insertion holes are made on one of the second fixing brackets 5, and the top of the connecting bracket 7 is inserted into these two insertion holes to further enhance the connection stability between the entire regulating mechanism and the reactor body.

[0029] This application is for the field of water-cooled reactors, but can also be used in other fields where this application applies.

[0030] In another embodiment: Reference Figure 1-4 A horizontal conjugate water-cooled reactor: A first pipe for connecting to an external cold water pipe and a second pipe for discharging are fixedly installed on both sides of the cooling tank 6, and flanges are welded onto the first and second pipes. The first and second pipes are connected to the external cold water pipes through the flanges to ensure a tight connection without leakage, so that the external cold water can smoothly enter the cooling tank 6 for cooling and discharge the water after absorbing heat.

[0031] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
