The two copper bars 106 are used to install the output end and input end of the coil respectively, wherein the output end is uniformly fixed on one copper bar 106, and the input end is uniformly fixed on the other copper bar 106.

[0034] like Figure 3 and Figure 4 As shown, a plurality of insulating rods are arranged in a circular array between the top fixing bracket and the bottom fixing bracket, and a ring skeleton is fixed in the middle of the plurality of insulating rods. The ring skeleton is composed of a first semicircular ring 112 and a second semicircular ring 113. Figure 5As shown, the first semicircular ring 112 and the second semicircular ring 113 are both provided with notches, and the notches at the two locations are adapted to each other. The two notches are fixed at the joint by bolts. After being fixed, the first semicircular ring 112 and the second semicircular ring 113 form a complete circular skeleton. Several large holes are opened on the circular skeleton to help dissipate heat from the reactor 100. The remaining holes are fixed bolt holes. The holes are arranged in a circular shape. After the bolts are installed, they are used to limit and shape the support skeleton.

[0035] like Figure 3 and Figure 4 As shown, the circumferences of several insulating rods are respectively on the circular skeleton. The insulating rod includes an internal screw 110 and support members 109 at both ends. The support member 109 is sleeved on the outside of the internal screw 110. During installation, the two ends of the internal screw 110 are fixed to the third fixing plate 104 and the first fixing plate 101 at the upper and lower ends by bolts. The circular skeleton is fixed to the middle thread of the internal screw 110 by installing nuts 111. The support members 109 at both ends are respectively located at the upper and lower ends of the circular skeleton to play a supporting role.

[0036] like Figure 4 As shown, support frames are fixed to the upper and lower ends of the circular ring frame. The support frames include a first splicing plate 114 and a second splicing plate 115. The first splicing plate 114 and the second splicing plate 115 are spliced ​​together to form a circular ring. The first splicing plate 114 and the second splicing plate 115 are 2mm insulating plates, which are connected and fixed with insulating bolts to support the circular coil.

[0037] like Figure 2 As shown, coils are fixed on the annular frame and the supporting frame by fixing clamps and glue. The coils are connected in series by a number of turns and finally in parallel. The coils include a number of coils 105. In this embodiment, there are 32 groups of coils 105, of which 4 coils 105 are connected in series as a group and 8 groups are connected in parallel. The 8 coil heads are pressed onto terminals 107 and fixed onto a copper bus 106 via a fixing mechanism 108, serving as the input end of the reactor 100. The 8 coil ends are pressed onto terminals 107 and fixed onto another copper bus 106 via a fixing mechanism 108, serving as the output end of the reactor 100. The fixing mechanism 108 includes bolts and matching nuts.

[0038] The terminals 107 in this embodiment include a circular sleeve type and a U-shaped insertion type. When the circular sleeve type is used, several terminals 107 need to be inserted into the bolt first and then fixed by screwing the fixing nut. When the U-shaped insertion type is used, several terminals 107 need to be inserted horizontally into the bolt and then fixed by screwing the nut.

[0039] like Figure 10As shown, the present invention takes the design of a 900A, 0.1mh inductor as an example. Four coils 105 with appropriate turns are connected in series as a group, and a total of 8 groups are provided. The 8 groups are then connected in parallel. The beginning of the 8 groups of coils 105 are connected in parallel as the input end of the inductor 100, and the end of the 8 groups of coils 105 are connected in parallel as the output end of the inductor 100.

[0040] During the assembly of the reactor 100 , there are a large number of terminals 107 , which need to be inserted or inserted one by one, and then the nuts need to be tightened one by one. The assembly process is relatively cumbersome and inconvenient. Therefore, this embodiment proposes an auxiliary installation mechanism 200 for assisting the assembly of the terminals 107 .

[0041] like Figure 6 As shown, the auxiliary installation mechanism 200 includes a U-shaped base plate 201, a first sliding groove 203 is opened at the bottom of the U-shaped base plate 201, a sliding clamping plate 204 is slidingly provided on the first sliding groove 203, a convex plate 211 is fixedly provided at one end of the U-shaped base plate 201, the sliding clamping plate 204 and the convex plate 211 are fixedly connected by a first spring 202, and a fixed clamping plate 205 is also fixedly provided at one end of the bottom of the U-shaped base plate 201. When in use, the sliding clamping plate 204 is pressed against the third fixed plate 104, and the first spring 202 is compressed backward, so that the sliding clamping plate 204 and the fixed clamping plate 205 can clamp and fix the third fixed plate 104, so that the auxiliary installation mechanism 200 is fixed as a whole.

[0042] like Figure 6 and Figure 7 As shown, the two U-shaped legs on the U-shaped bottom plate 201 are provided with a through-slot (such as Figure 6 As shown, the through chute is not marked), and the two through chute are slidably fitted with a sliding plate 206, as shown in FIG. Figure 8 and Figure 9 As shown, the two sliding plates 206 are fixedly connected to the horizontal plate 209 through a plurality of first telescopic rods 208, and the second springs 207 are sleeved outside the plurality of first telescopic rods 208. Figure 7 As shown, a plurality of wire clips 210 are fixed on the horizontal plate 209. Figure 9 As shown, several wire clamps 210 are symmetrically provided with elastic members 213 inside. When the wire is pushed downward from the top of the wire clamp 210, the elastic member 213 is deformed and the wire is clamped and fixed in the wire clamp 210. When the wire clamp 210 is moved downward, the wire is separated from the wire clamp 210. When in use, the two sliding plates 206 are pushed to adjust the horizontal plate 209 so that it can be horizontally displaced.

[0043] like Figure 7A plurality of second sliding grooves 214 are provided on the top of the U-shaped bottom plate 201 shown. A moving part 215 is slidably provided on the plurality of second sliding grooves 214. A rotating part 216 is rotatably provided on the moving part 215. A plurality of second telescopic rods 217 are fixedly provided at both ends of the rotating part 216. A mounting bracket 219 is fixedly provided at the extended end of the plurality of second telescopic rods 217. A third spring 218 is also sleeved on the plurality of second telescopic rods 217 at a position between the rotating part 216 and the mounting bracket 219. Second adjustment plates 220 are also fixedly provided at symmetrical positions on the mounting brackets 219 on both sides. A cylindrical friction part 212 is also fixedly provided on the mounting brackets 219 on both sides. The cylindrical friction part 212 is made of elastic material.

[0044] When in use, first install the auxiliary installation mechanism 200 as a whole between the two copper bars 106 of the reactor 100 through the sliding clamp 204 and the fixed clamp 205, and then fix the terminals 107 of the output and input ends or the connecting wires of the terminals 107 on the two rows of wire clamps 210 respectively, and move the wire clamps 210 horizontally to both ends to insert the U-shaped plug-in terminal 107 into the bolt, and then adjust the distance between the two cylindrical friction parts 212 so that it is in a tightening state with the fixing nut above the terminal 107. At this time, push the two cylindrical friction parts 212 forward to realize the rotation of the fixing nut under the action of friction force to tighten the fixing nut.

[0045] When the terminal 107 is of the ring-inserted type, the two rows of wire clamps 210 can be pulled upward to the appropriate height first, and then pushed to both sides. After being aligned with the bolt, the wire clamps 210 are lowered, and the terminal 107 is inserted into the bolt. Then, the fixing nut is tightened by rotating the two cylindrical friction parts 212 in the same way as above. If there are some that are not completely tightened after tightening, manual reinforcement can be performed.
