[0002] The reactor is a high-voltage electrical appliance used for limiting short-circuit current, stabilizing voltage, reactive power compensation and phase shifting. The reactor in the prior art is generally composed of a mounting frame and a coil. During the production process, the coil needs to be assembled and fixed between two sets of mounting frames.

However, when tightening the coil in the prior art, the staff generally use tools to tighten the screw on one side first, and then tighten the screw on the other side. During the tightening operation, when one side of the coil is compressed, the coil itself may slide sideways, and the installation accuracy may not be high. Summary of the invention

DETAILED DESCRIPTION

[0059] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0060] Embodiment 1:

[0061] Reference Figure 1-Figure 7 , a reactor, comprising:

[0062] A first mounting frame 2 and a second mounting frame 4 are symmetrically arranged;

[0063] The second mounting frame 4 is located directly above the first mounting frame 2;

[0064] The first mounting frame 2 and the second mounting frame 4 are both connected with an iron core plate 3;

[0065] The coil 5 is connected between the first mounting frame 2 and the second mounting frame 4;

[0066] A pressing plate 12 connected to the second mounting frame 4;

[0067] A rotating rod 901 is rotatably connected to the pressing plate 12;

[0068] The first pressure rod 9 is fixedly connected to the rotating rod 901;

[0069] A connecting sleeve 10 is threadedly connected to the first pressure rod 9;

[0070] The second pressure rod 8 is threadedly connected to the connecting sleeve 10;

[0071] The mounting block 801 is fixedly connected to the second pressure rod 8;

[0072] The mounting seat 7 is fixedly connected to the first mounting frame 2, and the mounting seat 7 is located directly below the pressing plate 12;

[0073] The mounting groove 701 is provided in the mounting seat 7, and the mounting block 801 is engaged with the mounting groove 701;

[0074] A connecting ring 1102 is rotatably connected to the connecting sleeve 10;

[0075] The limiting clamping plate 11 is fixedly connected to the connecting ring 1102;

[0076] The first pressure rod 9 drives the connecting sleeve 10 to rotate, the connecting sleeve 10 drives the second pressure rod 8 to rotate, the second pressure rod 8 drives the mounting block 801 to rotate into the mounting seat 7, and the connecting sleeve 10 synchronously drives the limiting clamping plate 11 to rotate and abut against the coil 5.

[0077] A placement groove 703 is provided in the mounting seat 7 , and a limiting block 702 is slidably connected in the placement groove 703 . The limiting groove 802 is provided on the mounting block 801 , and the limiting block 702 matches the limiting groove 802 .

[0078] Reference Figure 1-Figure 7 During the installation process, align multiple groups of core plates 3 and place them between two groups of first mounting frames 2, and tighten them with the third fastening bolts 6, then place three groups of coils 5 on the assembled first mounting frame 2, and then align multiple groups of core plates 3 and place them between two groups of second mounting frames 4, and tighten them with the third fastening bolts 6. After the assembly is completed, place them on the coils 5, and clamp the pressure plate 12 with the first pressure rod 9 in the second card groove 401. The staff then rotates the first pressure rod 9 to make the mounting block 801 fit into the mounting seat 7, and makes the limiting card plate 11 press against the coil 5, and synchronously rotates the connecting sleeves 10 on both sides to drive the first pressure rod 9 and the second pressure rod 8 to approach each other, and the pressure plate 12 presses the coil 5.

[0079] Reference Figure 2 , Figure 3During the rotation of the first pressure rod 9, the first pressure rod 9 will drive the connecting sleeve 10 to rotate, and the rotation of the connecting sleeve 10 will drive the connecting ring 1102 to rotate, and the rotation of the connecting ring 1102 will drive the limiting card plate 11 to rotate. After the limiting card plate 11 rotates a certain angle, the limiting card plate 11 will clamp multiple groups of coils 5 and clamp the multiple groups of coils 5 tightly. The inner wall of the limiting card plate 11 will abut against the side wall of the coil 5. At this time, when the staff rotates the connecting sleeves 10 on both sides synchronously, the limiting card plate 11 will limit the coil 5. At this time, when the coil 5 is pressed, it can effectively solve the problem of the side slip deviation of the coil 5 caused by the tightening pressure on one side in the prior art, thereby improving the installation accuracy;

[0080] Reference Figure 2 , Figure 3 When the limit card plate 11 rotates to clamp the coil 5, the limit card plate 11 will push the coil 5, so that the coil 5 can be effectively clamped in the limit card plate 11. The position of the coil 5 can be fine-tuned during the pushing process, thereby effectively solving the problem of position deviation caused by inaccurate placement of the staff in the prior art, and ensuring that the coil 5 as a whole can be stably placed in the middle position of the first mounting frame 2.

[0081] A first magnet 8021 is fixedly connected in the limiting groove 802 , and a second magnet 7021 is fixedly connected to the limiting block 702 . The first magnet 8021 and the second magnet 7021 attract each other.

[0082] It should be noted that both the first magnet 8021 and the second magnet 7021 can be strong magnets to further improve the installation stability of the installation block 801 .

[0083] Reference Figure 7 When the mounting block 801 is inserted into the mounting groove 701, the first magnet 8021 in the limiting groove 802 will attract the second magnet 7021 on the limiting block 702, thereby ensuring the installation stability of the mounting block 801 and reducing the possibility of the mounting block 801 falling off when the coil 5 is subsequently pressed.

[0084] A first spring 7031 is fixedly connected in the placement groove 703 , and one end of the first spring 7031 away from the inner wall of the placement groove 703 is fixedly connected to the limiting block 702 .

[0085] Reference Figure 7 By setting the first spring 7031 on the limiting block 702, the limiting block 702 can be quickly bounced into the limiting groove 802.

[0086] Embodiment 2:

[0087] Reference Figure 1-Figure 7, a reactor, which is basically the same as that of embodiment 1, and further, a pressure sensor 15 is fixedly connected to the bottom of the first pressure rod 9.

[0088] The pressure sensor 15 is a commercially available sensor, and a signal sending device is built into the sensor to transmit pressure data to an external display screen.

[0089] Reference Figure 2 , Figure 6 When the staff manually rotates the connecting sleeve 10, the first pressure rod 9 and the second pressure rod 8 rotate closer to each other. After the second pressure rod 8 approaches the first pressure rod 9 for a certain distance, the second pressure rod 8 will squeeze the driving end of the pressure sensor 15. The pressure sensor 15 will upload the pressure value to the external display screen in real time. After rotating a certain number of circles, the staff can judge the clamping effect of the pressure plate 12 on the coil 5 through the pressure value on the display screen. At the same time, it can also prevent the pressure plate 12 from excessively squeezing the coil 5 due to excessive rotation of the connecting sleeve 10, causing damage.

[0090] An insulating rubber pad 1101 is fixedly connected to the inner wall of the limiting clamping plate 11 .

[0091] Reference Figure 3 , Figure 5-Figure 6 By setting the insulating rubber pad 1101 on the limiting card plate 11, the problem that the limiting card plate 11 easily scratches the coil 5 when it is against the clamping coil 5 can be effectively solved.

[0092] A first card slot 1201 is defined at the bottom of the pressing plate 12 , and a second card slot 401 is defined on the second mounting bracket 4 . The first card slot 1201 is matched and locked in the second card slot 401 .

[0093] Reference Figure 1 , Figure 4 By setting the first card slot 1201 and the second card slot 401, it can be ensured that when the pressing plate 12 is placed on the second mounting frame 4, it can be accurately placed directly above the mounting seat 7, and at the same time, the stability of the pressing plate 12 placed on the second mounting frame 4 can be improved.

[0094] Embodiment 3:

[0095] Reference Figure 8-Figure 10 , a reactor housing, including a reactor, further comprising:

[0096] Housing 13;

[0097] A connecting frame 1, fixedly connected to the bottom of the first mounting frame 2;

[0098] A first mounting hole 101 is provided on the connecting frame 1;

[0099] The first fastening bolt 102 is threadedly connected in the first mounting hole 101 , and the first fastening bolt 102 is threadedly connected to the housing 13 .

[0100] The housing 13 is provided with a second mounting hole 1301 . The housing 13 is connected to the cover plate 14 via a second fastening bolt 1401 . The second fastening bolt 1401 is threadedly connected to the second mounting hole 1301 .

[0101] Reference Figure 8 , Fig. 9 By setting the cover plate 14 on the housing 13, it is possible to reduce the dust from entering the housing 13, thereby reducing the possibility of damage to the reactor body and increasing the service life of the reactor body.

[0102] A second spring 1103 is fixedly connected to the side wall of the limiting card plate 11. When the inductor is installed in the housing 13, one end of the second spring 1103 away from the limiting card plate 11 abuts against the inner wall of the housing 13, and a shock absorbing effect is achieved by setting the second spring 1103.

[0103] Embodiment 4:

[0104] An assembly process of a reactor, the assembly steps are as follows

[0105] Step 1: align multiple groups of core plates 3 and place them between two groups of first mounting frames 2, and tighten them with third fastening bolts 6;

[0106] Step 2: placing the coil 5 on the assembled first mounting frame 2;

[0107] Step 3: align multiple groups of core plates 3 and place them between two groups of second mounting frames 4, and tighten them with third fastening bolts 6. After assembly, place them on the coil 5;

[0108] Step 4: clamp the pressing plate 12 with the first pressing rod 9 into the second clamping slot 401;

[0109] Step 5: Rotate the first pressing rod 9 to make the mounting block 801 fit into the mounting seat 7, and make the limiting clamping plate 11 press against the coil 5;

[0110] Step 6: Rotate the connecting sleeve 10 to drive the first pressing rod 9 and the second pressing rod 8 to move closer to each other, and the pressing plate 12 presses the coil 5 tightly.

[0111] By using the device to assemble the reactor body, there is no need to tighten the bolts to tighten the coil 5, which improves the assembly efficiency. At the same time, the first pressure rod 9 and the second pressure rod 8 in the device drive the limit clamp 11 to rotate, thereby clamping the coil 5, thereby effectively solving the problem of lateral slippage of the coil 5 caused by the tightening force in the prior art, and improving the installation accuracy.

[0112] Embodiment 5:

[0113] Reference Fig.11 , Fig.12 A reactor is basically the same as the first embodiment, except that a first sliding plug 17 is slidably connected to the limit card plate 11, a stopper 19 is fixedly connected to the first sliding plug 17, the stopper 19 and the coil 5 are in contact with each other, a color development cavity 1901 is provided in the stopper 19, a liquid delivery cavity 1104 is provided in the limit card plate 11, a support rod 18 is fixedly connected to the limit card plate 11, and a plug 1801 is fixedly connected to the support rod 18;

[0114] Reference Fig.12 The plug 1801 is located directly above the first sliding plug 17 and is inserted into the through hole on the first sliding plug 17 .

[0115] A liquid storage cavity 16 and a liquid infusion tube 1602 are provided in the limiting clamping plate 11 . One end of the liquid infusion tube 1602 is connected to the liquid storage cavity 16 , and the other end of the liquid infusion tube 1602 is connected to the liquid delivery cavity 1104 .

[0116] It should be noted that, in a specific implementation, a pressure pump may be provided at the bottom of the limiting clamping plate 11 , a pressure tube 1601 is connected to the driving end of the pressure pump, and the pressure tube 1601 is communicated with the liquid storage chamber 16 .

[0117] Reference Fig.11 , Fig.12 When the limiting card plate 11 and the side wall of the coil 5 are in contact with each other, pressure is applied to the liquid storage chamber 16. If there is a gap between the coil 5 and the limiting card plate 11, the color developing liquid in the liquid storage chamber 16 enters the liquid delivery chamber 1104 through the infusion tube 1602. The liquid in the liquid delivery chamber 1104 will press the first sliding plug 17 to slide down, and the sliding of the first sliding plug 17 will push the cylinder 19 to move downward.

[0118] When the gap between the inner wall of the limiting clamping plate 11 and the coil 5 is small, the plug 1801 does not slide out of the first sliding plug 17, and the color developing liquid in the liquid delivery cavity 1104 cannot enter the color developing cavity 1901 for color development.

[0119] When the gap between the inner wall of the limiting card plate 11 and the coil 5 is large, the plug 1801 slides out from the first sliding plug 17. At this time, the plug 1801 and the first sliding plug 17 are separated, and the color developing liquid in the liquid delivery cavity 1104 flows into the color developing cavity 1901 through the through hole on the first sliding plug 17 for color development.

[0120] It should be noted that a one-way valve 20 is provided in the through hole of the first sliding plug 17 .

[0121] The device detects whether there is a gap between the coil 5 and the limit clamping plate 11 through the stop tube 19, so that the staff can quickly determine whether the coil 5 is offset during installation.

[0122] It should also be noted that the limit clamping plate 11 and the stop tube 19 are both made of transparent materials to facilitate observation by the staff.

[0123] It is also necessary to further explain that the multiple groups of coils 5 are bonded together by adhesive before installation, so that after the stop tube 19 is detected, the multiple groups of coils 5 can be adjusted synchronously, thereby further ensuring the installation accuracy of the coils 5.

[0124] Embodiment 6:

[0125] Reference Fig.13 , Fig.14 , a reactor, which is basically the same as Example 5, and further, a gear ring 1001 can be fixedly connected to the connecting sleeve 10, a second sliding plug 1603 is slidably connected in the liquid storage chamber 16, a rack 1604 is fixedly connected to the second sliding plug 1603, and the rack 1604 and the gear ring 1001 are meshed.

[0126] Reference Fig.14 When the connecting sleeve 10 rotates to lock the pressure plate 12, the connecting sleeve 10 drives the gear ring 1001 to rotate, and the gear ring 1001 will drive the gear rack 1604 meshing with it to move, thereby pushing the second sliding plug 1603 to slide to the left and apply pressure, so that the color-developing solution in the liquid storage chamber 16 enters the liquid delivery chamber 1104, and during the locking process, the staff can determine whether the coil 5 is offset.

[0127] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
