Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a tensioning structure for enhancing the stability of a dry-type iron core reactor. Background Art

[0002] Reactors, also known as inductors, are widely used in circuits. Due to the effect of electromagnetic induction in circuits, there is a certain inductance, which can prevent current changes. Dry-type iron core reactors are composed of multiple discs stacked and cast into a whole. In existing high-voltage products, the coils are connected by conductor materials and stainless steel tie rods, or an intermediate through-core structure is used in the three-phase core column.

[0003] However, for reactors with a relatively high overall height, it is difficult to tighten the above structure only by relying on the axial upper and lower pull rods, which will lead to instability of the overall structure. For high-voltage reactors, in order to ensure the insulation distance between the coils and the stainless steel pull rods, it is necessary to increase the distance between the coils or increase the length of the pull plate, which will lead to an increase in the product volume and thus increase the production cost. At the same time, the spacing between the coils on different types of iron core reactors is also different. Based on this, a tightening structure is now provided to enhance the stability of dry-type iron core reactors, which can eliminate the disadvantages of existing devices. Utility Model Content

The three fixing frames 208 are respectively sleeved on the outer walls of the second positioning plug-in plate 2011 and the two first positioning plug-in plates 206, and are fixedly connected to the extrusion assembly 4 by bolts. By plugging the second positioning plug-in plate 2011 into the fixing frames 208, the second connecting plate 2010 and the first connecting plate 205 can be preliminarily installed on the outer wall of one end of the extrusion assembly 4.

[0059] The interior of the three fixing frames 208 is provided with a second limiting component, which is used to limit the second positioning plugboard 2011 and the first positioning plugboard 206 in the longitudinal direction;

[0060] In one embodiment, Figure 2-Figure 4 As shown, the second limiting component includes:

[0061] The two fixed guide bars 207 are symmetrically fixedly connected to the inner wall of the fixed frame 208 . The second positioning plug plate 2011 and the first positioning plug plate 206 are both sleeved on the outer wall of the fixed guide bars 207 . The fixed guide bars 207 are used to slide and guide the second positioning plug plate 2011 .

[0062] The above embodiment discloses a tensioning structure for enhancing the stability of a dry-type iron core reactor. During installation, the present invention sequentially installs three fixing frames 208 on the bottom end of an extrusion assembly 4 by means of bolts, and sequentially installs another three fixing frames 208 on the top end of another extrusion assembly 4. Then, three solenoid bodies 1 are sequentially placed on the upper surface of one extrusion assembly 4. During this process, the iron core body 3, driven by the solenoid body 1, passes through the extrusion assembly 4 to penetrate the fixing frames 208. Then, another extrusion assembly 4 is sleeved on the top outer wall of the iron core body 3, thereby achieving preliminary installation and positioning of multiple solenoid bodies 1.

[0063] Then, according to the spacing between the three fixed frames 208, the two first connecting plates 205 are pulled respectively. At this time, the two first connecting plates 205 pull the two telescopic rods 201 through the first moving block 202, and the telescopic rods 201 are extended by pulling. When the two first connecting plates 205 are moved to the appropriate position, the pulling of the first connecting plates 205 is stopped, and then a telescopic component is pushed to contact the outer wall of an extrusion component 4. In this process, the second connecting plate 2010 contacts the outer wall of an extrusion component 4 by moving, and the second moving block 209 is on the second connecting plate 2 010, the two first moving blocks 202 are driven to move synchronously by the two telescopic rods 201 respectively. At this time, the first connecting plate 205 is driven by the first moving block 202 to contact the outer wall of the extrusion component 4. At the same time, the second positioning plugboard 2011 and the first positioning plugboard 206 are driven by the second connecting plate 2010 and the first connecting plate 205 respectively, and are synchronously inserted into one end of the three fixed frames 208, and the outer wall of the fixed guide bar 207 is sleeved. Then, the fixing plate 204 is fixedly connected to one end of an extrusion component 4 by bolts, thereby realizing the synchronous installation of the two telescopic rods 201;

[0064] After that, the rising operation is repeated, and the telescopic components can be installed and fixed on the two ends of the two extrusion components 4 in turn, and then the two telescopic components at one end of the two extrusion components 4 can be tightened by pulling the pull belt 203. The two extrusion components 4 can be driven by the telescopic components to squeeze the upper and lower ends of the three solenoid bodies 1 respectively, thereby effectively increasing the stability of the solenoid body 1 during use, effectively suppressing the vibration generated by the solenoid body 1 during use, reducing mechanical stress, preventing the iron core from shifting or the laminations from loosening, reducing the noise level, and reducing the spacing between the solenoid bodies 1.
