Description

Technical Field

[0001] The utility model relates to a reactor. Background Art

[0002] The base structure of the reactor product in the prior art is as follows Figure 1 The base comprises two support brackets 1 arranged at intervals, and two side surfaces of the reactor silicon steel lower yoke 2 are oppositely provided with clamping plates 3.

[0003] The reactor as a whole is installed in the electrical cabinet through the base. Usually, a mounting hole is set on the support bracket 1 of the base, and the fixing parts pass through the mounting hole to fix the reactor as a whole in the cabinet. Since the position of the reactor installation opening is precisely designed when the cabinet is designed, the reactor requires a relatively high base accuracy during installation. Therefore, when the product is produced in the factory, in order to ensure the accuracy requirements of the base installation holes, a special base tool is used to locate the relative size of the base and the lower yoke 2 and the clamping plate 3 of the reactor. After positioning, the clamping plate 3 and the support bracket 1 of the base are welded. After welding, the position between the clamping plate 3 and the base is relatively fixed to ensure the subsequent installation dimensions.

[0004] In order to ensure the accuracy of the welding position between the clamping plate 3 and the base, the commonly used welding tool is a welding base tool, such as Figure 2 As shown, it includes a bottom plate 401, a positioning block 402 and a positioning pin 403 arranged on the bottom plate 401, the position of the clamping plate 3 and the base is restricted and fixed by the position of the positioning block 402, and the positioning hole at the bottom of the support bracket 1 is inserted into the positioning pin 403. Due to the long-term use of the base positioning tooling, wear or deformation may occur, which may easily cause defects such as inaccurate positioning and large dimensional deviation.

[0005] In addition, during the welding process of the clamping plate 3 and the base, the welding slag will jump to the upper coil position of the reactor, and there is a risk of burning the insulation layer of the coil. The welding slag jumping to the clamping plate 3 will cause the clamping plate 3 to turn black, affecting the appearance of the product. Utility Model Content

[0047] The terms "first" and "second" are used for descriptive purposes only and are not used to imply relative importance.

[0048] The utility model provides a reactor, the structure of which refers to Figure 3 and Figure 4 .

[0049] The reactor includes three groups of cores and windings 5, the upper end of the core and winding 5 structure corresponds to the core upper yoke 8 and the core upper clamping plate 9, and the lower end of the core and winding structure corresponds to the core lower yoke 10 and the core lower clamping plate 11.

[0050] The core and winding 5 structure is supported by a base support bracket. The base support bracket includes a first side support bracket 6 and a second side support bracket 7 which are arranged opposite to each other at intervals;

[0051] The core lower clamping plate 11 includes a first side lower clamping plate and a second side lower clamping plate which are arranged opposite to each other at intervals; the two lower clamping plates 11 have the same structure. The two ends of each lower clamping plate 11 in the length direction are respectively arranged on the first side support bracket 6 and the second side support bracket 7.

[0052] The core lower yoke 10 is disposed between the two lower clamping plates, and both ends of the core lower yoke 10 in the length direction are supported by the first side support bracket 6 and the second side support bracket 7 respectively.

[0053] The first side lower clamping plate 11 , the second side lower clamping plate 12 and the core lower yoke 10 together form a structure spanning the first side supporting bracket 6 and the second side supporting bracket 7 .

[0054] The structures of the two base support brackets are the same. The structure of the first side support bracket 6 is taken as an example to illustrate its structure. Along the length direction of the first side support bracket 6, at least two positioning pins 601 are arranged on the base support bracket at intervals, and the positioning pins 601 are located on the end surface of the side where the base support bracket cooperates with the lower yoke 10 of the reactor core. One of the positioning pins 601 corresponds to the fixed position of the first side lower clamping plate 11, and the other positioning pin corresponds to the fixed position of the second side lower clamping plate 12, that is, the gap between the two positioning pins 601 is equal to the setting gap between the first side lower clamping plate 11 and the second side lower clamping plate 12. Since the lower yoke 10 of the core is set between the two lower clamping plates, this gap is approximately equal to the width of the lower yoke 10 of the core.

[0055] The structure of the second side support bracket 7 is the same as that of the first side support bracket 6 , and two positioning pins 701 are also provided accordingly, which will not be described in detail.

[0056] Each lower clamping plate has the same structure, and each lower clamping plate is provided with a positioning hole, and the position of the positioning hole matches the position of the positioning pin of the base support bracket, so that the lower clamping plate can be inserted into the positioning pin and fixed in position. The structure of the lower clamping plate is described by taking the structure of the first side lower clamping plate 11 as an example. The first side lower clamping plate 11 is provided with a positioning hole 1101, including at least two positioning holes 1101, which are respectively inserted and matched with the positioning pins 601 on the first side support bracket 6 and the second side support bracket 7. Correspondingly, the second side lower clamping plate 12 also has two positioning holes, which are respectively inserted and matched with the positioning pins 601 on the first side support bracket 6 and the second side support bracket 7.

[0057] The structure of the lower clamping plate is further described by taking the structure of the first side lower clamping plate 11 as an example. In some embodiments of the utility model, each lower clamping plate includes a main body 1102 and a first bending portion 1103 and a second bending portion 1104 bent relative to the main body 1102, the first bending portion 1103 and the second bending portion 1104 are arranged at intervals, and the first bending portion 1103 of each lower clamping plate is correspondingly arranged on the first side support bracket 6, and each second bending portion 1104 is correspondingly arranged on the second side support bracket 7. Correspondingly, the positioning holes 1101 are arranged on the first bending portion 1103 and the second bending portion 1104. The positioning holes 1101 on each bending portion correspond to the positioning pins inserted on the first side support bracket 6 and the second side support bracket 7.

[0058] In some embodiments of the present invention, the main body 1102 of each lower clamping plate is correspondingly attached to two opposite side surfaces of the core lower yoke 10 and is fixed to the core lower yoke 10 via a fixing member.

[0059] The structure of the base support bracket is further described by taking the structure of the first side support bracket 6 as an example. In some embodiments of the utility model, each base support bracket is U-shaped, including a first horizontal portion 602, a vertical portion 603 and a second horizontal portion 604, the positioning pin 601 is located in the first horizontal portion 602, and the second horizontal portion 604 is provided with a fixing hole. The first horizontal portion 602 is used for installation in conjunction with the base support bracket, and the second horizontal portion 604 is used for installation of the reactor as a whole.

[0060] In order to improve the stability of the matching structure between the lower clamping plate and the base support bracket, the two can be further fixed by bolts. In some embodiments of the utility model, the first horizontal portion 602 is further provided with a fixing hole 605, and the matching portion between each lower clamping plate and the first horizontal portion 602 is provided with a fixing installation hole 1105, and each lower clamping plate and each base support bracket are further fixed by a fixing member 13.

[0061] When assembling the reactor, the positioning pins on the base support frame and the positioning holes on the lower clamping plate are used to coordinate and initially fix the two, and then the two are further fixed by the fixing parts. The improved reactor base fixing structure no longer requires welding of the base and the lower clamping plate, which saves the overall processing steps of the reactor while ensuring the product processing quality.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
