Description

Technical Field

[0001] The invention relates to the technical field of transformer air cavity coils, and in particular to a low-noise high-overload energy storage transformer air cavity coil winding and a coil winding mechanism. Background Art

[0002] The load capacity of the transformer is directly related to the winding and the air cavity coil. The turns ratio of the winding directly affects the voltage transformation ratio of the transformer, and then affects its output power and current capacity. As the number of turns of the winding increases, a large amount of noise is generated due to problems such as core vibration, winding vibration, mechanical vibration, air flow, and electromagnetic radiation. For this reason, the noise reduction method of the transformer is particularly important. Please refer to the relevant content in publication numbers CN104851577A and CN111834091A.

[0003] It should be noted that: on the basis of conventional noise reduction technology (soundproof cover, shock absorption, sound-absorbing materials), the winding process can be further optimized. For example, the tightness and arrangement of the copper wire winding can be improved to address the causes of core vibration and winding vibration. However, it should be further noted that: too tight winding will lead to a decrease in the gap between turns of the coil, and reduce the capacitance between turns of the winding, thereby greatly increasing the leakage current of the equipment, increasing coil losses, and affecting the turn-to-turn voltage distribution. Loose windings will cause more problems, such as increased noise, shortened life, etc. The present invention proposes a solution to the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a low-noise high-overload energy storage transformer wind cavity coil winding and a coil winding mechanism. For the wind cavity coil in the high-overload transformer, its winding method is also one of the key technologies to reduce the transformer noise, but the tightness of the winding will further affect the equipment. For example, too tight will cause the gap between the turns of the coil to decrease, resulting in leakage and increased coil loss. The problem caused by too loose winding is particularly serious.

[0005] The purpose of the present invention can be achieved by the following technical solutions: a coil winding mechanism for a low-noise high-overload energy storage transformer wind cavity coil winding, applied in the winding process of the transformer wind cavity coil winding, comprises a coil winding body, a fixed base, a working frame and a head assembly, the head assembly comprises a mounting seat and a sliding plate, the mounting seat is arranged at the output position on the working frame, a reversing sleeve, a hemispherical sleeve and a winding column are arranged on the sliding plate in sequence, a directional support rod and a conductor rod are respectively installed on one side of the reversing sleeve in the direction from top to bottom, and an arc-shaped elastic plate is rotatably installed at one end of the directional support rod;

[0006] A threading arc tube is arranged at the center point of the inner part of the hemispherical sleeve, and the hemispherical sleeve and the winding column perform the winding detection action, and the reversing sleeve, the directional support rod and the conductor rod cooperate with the working frame to perform the winding reversing action.

[0007] It is further configured as follows: a driving push rod assembly is installed in the mounting seat, the sliding plate is slidably connected to the mounting seat through the driving push rod assembly, and a reversing motor is installed on the upper surface of the sliding plate.

[0009] It is further configured as follows: the directional support rod and the conductor rod are installed on the outer wall of another direction-adjusting gear, and guide grooves corresponding to the threading arc tubes are provided in the conductor rod and the other direction-adjusting gear.

[0010] It is further configured as follows: a line-pressing elastic plate is rotatably mounted on one side of the arc-shaped elastic plate, and a coil spring assembly is arranged at the rotation point between the arc-shaped elastic plate and the directional support rod.

[0011] It is further configured that: the center point position of the threading arc tube and the center point position of another direction adjustment gear are on the same horizontal axis.

[0012] It is further configured as follows: one-way balloons are installed on the outer position of the threading arc tube and the inner wall position of the hemispherical sleeve, and the one-way balloons are arranged in a ring array along the center point position of the threading arc tube.

[0015] The present invention has the following beneficial effects:

[0016] 1. According to the operating characteristics of the transformer wind cavity coil winding, the load capacity of the overall coil structure is increased by increasing the number of winding turns, and the operating noise is further reduced by changing the copper wire gap during winding. For this, a continuous winding action is formed based on the head assembly, and the directional 90-degree rotation action of the adjustment gear is specifically utilized, and the setting direction between the directional support rod and the conductor rod is further restricted. In the continuous winding action, the arc-shaped elastic plate on the directional support rod cooperates with the wire pressing elastic plate to continuously squeeze the copper wire after winding, which is used to maintain the copper wire after winding, and initially plays the purpose of maintaining the copper wire gap;

[0017] 2. Based on the above content, a hemispherical sleeve and a winding column are further set for the steering process of the steering gear. The interior of the hemispherical sleeve indirectly detects the copper wire winding force in the winding through the threading arc tube and the one-way balloon, and the winding column is mainly used to cooperate with the continuous winding action to further perform the winding action independently. In the basic winding and releasing action, the copper wire winding force detected by the one-way balloon is cooperated to further reel in and release the wire, thereby changing the copper wire winding force in the continuous winding action.

[0027] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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 are within the scope of protection of the present invention.

[0028] Embodiment 1: For the air cavity coil in the high overload transformer, its winding method is also one of the key technologies to reduce transformer noise, but the tightness of the winding will further affect the equipment. For example, too tight will cause the gap between the turns of the coil to decrease, resulting in leakage and increased coil loss. The problem of too loose winding is particularly serious. The following technical solution is proposed:

[0029] Reference Figures 1 to 7 The coil winding mechanism of the wind cavity coil winding of the low-noise high-overload energy storage transformer in this embodiment is applied in the winding process of the wind cavity coil winding of the transformer, and includes a coil winding body 1, a fixed base 2, a working frame 3 and a head assembly, the head assembly includes a mounting seat 4 and a sliding plate 5, the mounting seat 4 is arranged at the output position on the working frame 3, and a reversing sleeve 9, a hemispherical sleeve 7 and a winding column 6 are arranged on the sliding plate 5 in sequence, and a directional support rod 13 and a conductor rod 15 are respectively installed on one side of the reversing sleeve 9 in the direction from top to bottom, and an arc-shaped elastic plate 12 is rotatably installed at one end of the directional support rod 13;

[0030] A threading arc tube 20 is arranged at the inner center point of the hemispherical sleeve 7, and the hemispherical sleeve 7 and the winding column 6 perform the winding detection action, the reversing sleeve 9, the directional support rod 13 and the conductor rod 15 cooperate with the working frame to perform the winding reversing action, and a driving push rod assembly 14 is installed in the mounting seat 4. The sliding plate 5 is slidably connected to the mounting seat 4 through the driving push rod assembly 14, and a reversing motor 10 is installed on the upper surface of the sliding plate 5.

[0031] Basic principle: Figure 2 As an example, the transformer wind cavity coil winding structure used in the transformer is basically similar, and its essence is to set a plurality of coil structures according to the magnetic field superposition principle. Figure 2 Taking the structural characteristics in the example, the working frame 3 is essentially composed of the vertical moving structure, the lateral moving structure and the wire-retracting and releasing structure of the corresponding head assembly, wherein the vertical moving structure and the lateral moving structure respectively drive the head assembly to move in the up and down and left and right directions, and the wire-retracting and releasing structure performs directional wire-retracting and releasing according to the operation process of the vertical moving structure and the lateral moving structure, and in the winding process, the wire-retracting and releasing structure is specifically Figure 3 For example, the wire rod 15 in the head assembly starts to penetrate from the threading position in the coil winding structure. After the wire rod 15 moves a distance from top to bottom, the angle of the wire rod 13 is changed by the adjusting gear 16, based on the winding reversing action, and further moves a distance. After that, the winding is performed from bottom to top after the winding reversing action. In this way, the winding direction is controlled according to the direction set in the directional support rod 13 and the wire rod 15, and the continuous winding action is continued in this way.

[0032] Embodiment 2: Further explanation of the arc-shaped elastic plate in the specific winding action:

[0033] The reversing sleeve 9 is installed at one side of the sliding plate 5, and two meshing steering gears 16 are rotatably installed inside the reversing sleeve 9. The output shaft of the reversing motor 10 is connected to one of the steering gears 16. The directional support rod 13 and the wire rod 15 are installed on the outer wall of the other steering gear 16, and the wire rod 15 and the other steering gear 16 are provided with guide grooves corresponding to the threading arc tube 20. A wire pressing elastic plate 11 is rotatably installed at one side of the arc elastic plate 12, and a coil spring assembly 17 is provided at the rotation point of the arc elastic plate 12 and the directional support rod 13.

[0034] Solution Description: Combined Figures 2 to 4To illustrate, in the initial state, the total length of the arc-shaped elastic plate 12 and the directional support rod 13 is greater than the length of the conductor rod 15, and the length of the conductor rod 15 is greater than the length of the directional support rod 13, so in the initial winding action, one end of the conductor rod 15 is inserted into the threading groove in the winding coil as much as possible, and when the overall head assembly starts to move downward, the arc-shaped elastic plate 12 is blocked by the coil winding and deflected upward, and the coil spring assembly 17 between the arc-shaped elastic plate 12 and the directional support rod 13 is in a compressed state, but it needs to be kept The arc-shaped elastic plate 12 is also located in the threading groove in the winding coil. Specifically, the wire pressing elastic plate 11 on the arc-shaped elastic plate 12 always presses the copper wire. If the initial direction of the winding coil is from top to bottom, the directional support rod 13 is located on the upper side of the conductor rod 15, and it is also necessary to further limit the arc-shaped elastic plate 12 to bend in a direction close to one side, so that after the winding is completed for a certain distance through the conductor rod 15, the arc-shaped elastic plate 12 drives the wire pressing elastic plate 11 to squeeze the copper wire after the winding, so as to maintain the position of the copper wire after the winding;

[0035] like Figure 5 As shown, after one of the steering gears 16 is driven to rotate ninety degrees under the action of the reversing motor 10, the winding direction of the copper wire can be changed, forming a winding direction similar to a rectangle. In this process, the directional support rod 13 and the arc-shaped elastic plate 12 are always located in the "subsequent structure" of the conductor rod 15, thereby continuously squeezing the copper wire after winding, maintaining the copper wire in the overall continuous winding action, thereby avoiding the problem of increased operating noise due to differences in the copper wire gaps in the overall coil winding.

[0036] Embodiment 3: Supplementary explanation on the copper wire winding force in the continuous winding action:

[0037] A one-way balloon 19 is installed on the outer position of the threading arc tube 20 and the inner wall position of the hemispherical sleeve 7. The one-way balloon 19 is arranged in a circular array along the center point of the threading arc tube 20. The sliding plate 5 is installed with a detection component 8 corresponding to the hemispherical sleeve 7 and a wire-retracting motor 18 corresponding to the winding column 6. The detection component 8 is provided with a pressure detection structure corresponding to the one-way balloon 19. The winding column 6 is rotatably connected through the wire-retracting motor 18. The working frame 3 is provided with a vertical moving structure, a horizontal moving structure and a wire-retracting and -releasing structure corresponding to the head assembly.

[0038] Solution description: As shown in the second embodiment, one of the directional gears is key to changing the winding direction during the winding process. Figure 4 and Figure 6For example, the steering gear 16 is also provided with an opening corresponding to the copper wire, and further maintains that the center point position of the threading arc tube 20 and the center point position of the steering gear 16 are in the same horizontal plane and the same vertical plane. Taking the three-dimensional coordinate system as an example, the center point position of the threading arc tube 20 and the center point position of the steering gear 16 are in the XZ and XY planes, and the winding column 6 is also provided with an opening corresponding to the copper wire. The opening on the winding column 6 and the threading arc tube 20 are only in the XY plane, but the opening 6 on the winding column 6 is always lower than the center point position of the steering gear 16. The unidirectional rotation angle of the steering gear 16 according to the winding direction is 90 degrees, so the steering gear 16 will not affect the conductor rod 15 in multiple rotation actions;

[0039] Combined with Figure 6 and Figure 7 It is explained that: because the single rotation angle of the steering gear 16 is 90 degrees, the setting value of the one-way balloon 19 is 4, and it is specifically set in the up and down and left and right directions according to the rotation direction of the steering gear 16, so as to Figure 6 Taking the steering gear 16 in the example, the opening and the center point of the steering gear 16 are on the same XY plane, and are specifically arranged at the left side of the center point of the steering gear 16. Then, in the continuous winding action, the threading arc tube 20 in the hemispherical sleeve 7 is affected by the copper wire and moves to the left side, causing the one-way balloon 19 in the corresponding position to undergo directional deformation. In this regard, the pressure change in the single-core balloon 19 due to the volume change can be further understood as follows: when the copper wire winding force is large in the overall continuous winding action, the copper wire will also drive the threading arc tube 20 to further squeeze the one-way balloon 19 in the corresponding position. It can be directly understood that the pressure change inside the one-way balloon 19 is proportional to the copper wire winding force;

[0040] Further explanation is given for the winding post 6: in the initial state, the opening in the winding post 6 is completely parallel to the length direction of the guide rod 15, so the copper wire can continue to pass through the opening in the winding post 6, and the overall winding process is specifically carried out by the retractable and rewinding structure in the working frame 3. However, in the specific process, if the retractable and rewinding action performed by the retractable and rewinding structure is relatively positioned, the winding post 6 can be further rotated, resulting in an increase in the winding distance of the copper wire in the winding post 6, thereby increasing the winding force during the copper wire winding process. For this purpose, it is necessary to further limit the rotation angle of the winding post 6 to 0 to 180°. When the retractable and rewinding action of the retractable and rewinding structure in the working frame 3 is relatively stable, assuming that the angle between the opening direction of the winding post 6 and the guide rod 15 is 30°, and further rotates to 40°, the winding force is increased. On the contrary, when the rotation angle is 30°, the winding force will be reduced, thereby achieving the purpose of controlling the winding force. The winding force and the number of winding turns are specifically determined according to the process parameters and are not limited in the present invention.

[0041] In summary: Aiming at the low noise and high load operating characteristics of the transformer coil winding, the number of winding turns and the tightness of the copper wire during winding are increased, and based on the machine head assembly, the winding angle is first changed by the reversing gear, and the synchronous wire pressing action is further achieved through the wire pressing elastic plate that cooperates with the directional support rod. The wire pressing action will not interfere with the winding action. The key is: to maintain the specific position of the copper wire after winding in real time in conjunction with the winding action, so as to maintain the copper wire gap after winding, and secondly, to further change the tightness of the copper wire during the winding process through the hemispherical sleeve, the threading arc tube and the winding column. In conjunction with the low noise operating characteristic, the winding tightness is changed on the basis of increasing the number of turns to maintain the structural stability of the overall coil winding.
