Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 2, a reactor coil regulation system includes: a height adjusting device 100 attached to a bottom of a coil of the reactor; the connecting device 200 is arranged between the height adjusting device 100 and the adjusting control device 300 and is used for movably connecting the height adjusting device 100 and the adjusting control device 300; and the adjusting and controlling device 300 is fixedly arranged on a bus bar of the reactor and is used for acquiring distance information between the adjusting and controlling device 300 and the height adjusting device 100 and controlling the connecting device 200 to drive the height adjusting device 100 to move according to the distance information so as to adjust the winding height of a coil attached to the height adjusting device 100 to be consistent with a design value.
Specifically, in the solution of this embodiment, a coil of a reactor is wound as shown in fig. 1, the reactor is specifically a dry-type air-core reactor, and the bottom of the coil of the reactor refers to one of two open surfaces formed by the cylindrical coil when the coil is wound to form a cylindrical shape, the two open surfaces being provided with the supporting pads. When the coil of the reactor is wound, a plurality of coils need to be wound outwards along the radial direction from the central axis, and the radius of the coil is larger towards the outside. The winding height of the coil is the height of the cylindrical shape, i.e. the distance between two open faces of the cylindrical coil.
The height adjusting device 100 is movably connected with the adjusting control device 300 through the connecting device 200, the height adjusting device 100 is attached to the bottom of the coil, when the coil of the reactor sinks or is lifted, the height adjusting device 100 correspondingly sinks or lifts under the action force of the sinking or lifting of the coil, and the sinking or lifting distance of the height adjusting device 100 is consistent with the sinking or lifting distance of the coil. Referring to fig. 3, in one embodiment, after the reactor coil adjusting system is fixedly disposed at the bottom of the coil, the distance between the adjusting control device 300 and the bus bar disposed at the top is fixed, and when the coil sinks or rises, the height adjusting device 100 moves along with the coil, so that the distance between the height adjusting device 100 and the adjusting control device 300 moves according to the height of the coil.
Therefore, in this embodiment, by detecting the distance information between the height adjusting device 100 and the adjusting control device 300, when the distance information changes, that is, the winding height of the coil is changed. If the distance information is reduced, the winding height of the coil is increased, and the coil sinks; if the distance information is increased, it indicates that the coil is lifted up due to a lack of turns or the like.
When the coil sinks or is lifted, the adjusting control device 300 detects distance information between the coil and the height adjusting device 100, then obtains a height adjusting value required when the winding height of the coil is adjusted to be consistent with a design value according to the distance information, finally generates a corresponding adjusting signal according to the height adjusting value, and controls the connecting device 200 to drive the height adjusting device 100 to move, so that the height adjusting operation of the coil is realized.
The distance between the adjusting and controlling device 300 and the bus bar disposed at the top is a fixed value, and when the winding height of the coil is consistent with the design value, since the height of the height adjusting device 100 is fixed, the distance between the height adjusting device 100 and the adjusting and controlling device 300 is also kept at a fixed value, and is recorded as an initial distance value. When analyzing whether the coil sinks or rises, it is only necessary to compare whether the distance information between the height adjustment device 100 and the adjustment control device 300, which is obtained by real-time detection, changes from the initial distance value.
It should be noted that, because the coils of the reactor are usually required to be wound from the central axis radially outward when being wound, in one embodiment, in order to achieve the winding height adjustment of the plurality of coils in the same reactor, reactor coil adjusting systems may be disposed at the bottoms of different coils to respectively achieve the height adjustment of the different coils, so that the winding heights of all the coils are finally kept consistent with the design value, and the problems of large reactor structural parameter difference and local coil overheating are avoided.
Further, in one embodiment, due to the process parameters of coil winding and the like, even if the heights of the same coil at different circumferential positions are not necessarily the same, a plurality of reactor coil adjusting systems can be arranged at different positions of the bottom of the same coil, so that height adjusting operations of the same coil at different positions can be realized.

Specifically, the adjusting control device 300 specifically includes two parts, namely a fixing component 320 and an adjusting control component 310, wherein the fixing component 320 is used for fixedly arranging the whole adjusting control device 300 on the bus bar, so that when the coil sinks or rises, the whole adjusting control device 300 does not sink or rise, but only the height adjusting device 100 movably connected with the adjusting control device 300 moves along with the coil. The adjustment control component 310 is used to detect the distance information between the adjustment control device 300 and the height adjustment device 100, and the distance information is specifically the distance information between the fixing component 320 and the height adjustment device 100. And then, analyzing according to the distance information to obtain a height adjusting value required for adjusting the winding height of the coil to be consistent with a design value, finally generating a corresponding adjusting signal according to the height adjusting value, and controlling the connecting device 200 to drive the height adjusting device 100 to move so as to realize the height adjusting operation of the coil.
It should be noted that the manner of disposing the adjustment control assembly 310 on the fixing assembly 320 is not exclusive, and in one embodiment, the adjustment control assembly 310 may be disposed inside the fixing assembly 320, and the connecting device 200 is connected to the adjustment control assembly 310 inside the fixing assembly 320 through an extension of an outer wall of the fixing assembly 320, so that the connecting device 200 can move the height adjustment device 100 under the control of the adjustment control assembly 310. In another embodiment, the adjusting control assembly 310 may be disposed on an outer wall of the fixing assembly 320, and then the fixing assembly 320 is fixed to the bus bar, and the connecting device 200 is connected to the adjusting control assembly 310, so long as the adjusting control assembly 310 can detect a distance change between the height adjusting device 100 and the adjusting control device 300 in real time, and the distance change is caused by the sinking or the lifting of the coil, and the height adjustment of the coil is achieved.

In this embodiment, the adjustment control component 310 is connected to the upper computer 330, the upper computer 330 receives the distance information collected by the adjustment control component 310, then obtains a height adjustment value required when the winding height of the coil is adjusted to be consistent with a design value according to the distance information, finally generates a corresponding adjustment signal according to the height adjustment value, and sends the adjustment signal to the adjustment control component 310. At this time, the adjustment control unit 310 only needs to drive the connection device 200 according to the adjustment signal. It should be noted that the specific type of the upper computer 330 is not exclusive and may be a personal computer, a mobile phone, a tablet computer, or the like.
For example, in an embodiment, please refer to fig. 4 or 5, the adjustment control assembly 310 includes a distance detector 311, a driver 313 and a controller 312, the distance detector 311 and the driver 313 are respectively connected to the controller 312 (not shown), the connection device 200 is disposed on the driver 313, and the distance detector 311, the driver 313 and the controller 312 are disposed on the fixing assembly 320.
Specifically, in the scheme of this embodiment, the distance detector 311 is used to perform a real-time detection operation on the distance information between the height adjustment device 100 and the adjustment control device 300, and the detected distance information is sent to the controller 312 or the upper computer 330 for analysis, and specifically, the distance information may be sent to the controller 312 or the upper computer 330 for analysis according to different positions of the adjustment signal analysis logic executed in different embodiments. When the regulation control device 300 includes the fixing member 320, the regulation control member 310, and the upper computer 330 at the same time, the upper computer 330 is specifically connected to the distance detector 311 and the controller 312 of the regulation control member 310.
When the controller 312 or the upper computer 330 analyzes that the coil sinks or is lifted according to the distance information, so that the winding height is inconsistent with the design value, the controller 312 or the upper computer 330 further analyzes according to the current distance information to obtain a driving signal required when the coil is adjusted to the design value and sends the driving signal to the driver 313, or obtain an adjusting signal required when the coil is adjusted to the design value and sends the adjusting signal to the controller 312, and the controller 312 further analyzes the driving signal and sends the driving signal to the driver 313. Under the action of the driving signal, the driver 313 drives the connecting device 200 to drive the height adjusting device 100 to move, and finally the height of the coil is adjusted to be consistent with the winding height.

The specific type of the displacement sensor is not exclusive, and in one embodiment, the displacement sensor may be an ultrasonic sensor, a photoelectric sensor, a potentiometer sensor, or any other sensor as long as the distance information between the height adjusting device 100 and the adjusting control device 300 can be detected.
In a more detailed embodiment, the ultrasonic sensor is taken as an example for detailed explanation, please refer to fig. 6, and the ultrasonic sensor includes three parts: the ultrasonic transducer (namely a transmitter and a receiver), the processing module and the output unit, wherein the processing module firstly applies voltage excitation to the ultrasonic transducer, the ultrasonic transducer emits ultrasonic waves to a measured object in a pulse form after being excited, then the ultrasonic transducer is switched into a receiver state to receive sound waves reflected by the measured object, and the processing module analyzes the received ultrasonic pulses and judges whether the received signals are ultrasonic echoes emitted or not. If so, measuring the travel time of the ultrasonic wave, and converting the travel time into half of the travel according to the measured time, namely the object distance of the ultrasonic wave. The ultrasonic sensor utilizes the piezoelectric effect principle to convert electric energy and ultrasonic waves into each other, namely when the ultrasonic waves are transmitted, the electric energy is converted to transmit the ultrasonic waves; when receiving the echo, the ultrasonic vibration is converted into an electric signal. Meanwhile, the high-precision ultrasonic sensor can realize the repetition precision of 0.6mm in a wide temperature range, and can effectively meet the requirement of adjusting the height of the coil.
The driver 313 is a device for driving, and this embodiment is implemented by using a stepping motor, the controller 312 obtains a driving signal required to adjust the height of the coil to a design value according to the analysis, and sends the driving signal to the stepping motor, and the stepping motor rotates under the action of the driving signal to drive the height adjusting device 100 to move, so that the coil attached to the height adjusting device 100 changes correspondingly in the winding height direction, and the adjustment of the winding of the coil is implemented.
Likewise, the type of the driver 313 is not limited to the stepping motor in this embodiment, and in other embodiments, other types of devices can be used as long as the height adjusting device 100 can be driven to move under the control of the controller 312. The controller 312 may be any one of a single chip, a field programmable gate array, and a micro control unit, and in other embodiments, a digital signal processing unit (DSP) may be used, as long as a processor capable of analyzing the received distance information to obtain a type of control signal required by the driver 313.
Referring to fig. 4 or 5, in an embodiment, the fixing assembly 320 includes a bracket 321 and a screw fixing tube 322, the adjusting control assembly 310 is disposed on the bracket 321, and the bracket 321 is fixedly connected to the bus bar through the screw fixing tube 322.
Specifically, in the present embodiment, the fixing assembly 320 is screwed to the bus bar of the reactor through the fixing threaded pipe, the bracket 321 is provided with a threaded through hole, and the bus bar is also provided with a threaded through hole of the same size.
It should be noted that the specific type of the support 321 is not exclusive, and in one embodiment, referring to fig. 7 in combination, in order to match with the bus bar of the reactor, the support 321 may be configured to be Y-shaped, that is, the support 321 includes two prongs and a support portion, the two prongs are provided with threaded through holes at the same height, and the adjustment control assembly 310 is provided on the support portion, and may be specifically disposed inside the support portion. When the coil height is adjusted, only two fork arms are required to be fixed with the threaded through holes of the bus bar through the same fixing threads, and the arrangement of the reactor coil adjusting system is completed.
It is understood that in other embodiments, the support 321 may be configured in other shapes such as an H-shape. The specific type of the connection device 200 is not exclusive, as long as the height adjustment device 100 can be connected with the adjustment control device 300 so that the height adjustment device 100 can move under the driving of the adjustment control device 300. For example, in one embodiment, the coupling device 200 is a threaded pipe.
In the solution of this embodiment, the height adjustment device 100 is connected to the adjustment control device 300 by using a threaded pipe, and when the adjustment control device 300 adjusts the height of the coil according to the collected distance information, the height adjustment device 100 can be adjusted up or down by a certain height by driving the threaded pipe to rotate, so that the winding height of the coil is correspondingly reduced or increased to meet the design value.
In order to facilitate understanding of various embodiments of the present application, the following explanation is made with an adjustment control device 300 including an upper computer 330, a fixing assembly 320, and an adjustment control assembly 310, the adjustment control assembly 310 including a distance detector 311, a stepping motor type driver 313, and a controller 312, and the fixing assembly 320 including a Y-shaped bracket 321 and a screw fixing tube 322.
Referring to fig. 3, the top of the height adjusting device 100 is closely attached to the bottom of each layer of coil, and the middle empty slot of the fixing component 320 is clamped on each arm of the reactor bottom bus bar and fixed by a screw fixing tube 322 passing through a pre-opened screw through hole on the arm, and the screw fixing tube 322 is fixed by a screw bolt which can be tightened if necessary. Because the reactor generally has a plurality of bus support arms, and a reactor coil adjusting system is installed on each corresponding bus support arm, the height of each layer of coil in each direction of the circumference can be conveniently adjusted. In addition, because the reactor needs to wind a plurality of coils from the axis outwards along the radial direction, the more outwards, the larger the coil radius, and in order to adjust the height of each coil, a plurality of holes need to be opened on each bus support arm to facilitate the fixing of the thread fixing pipe 322 on the bus support arm. It will be appreciated that the number of openings in the busbar is generally the same as the number of coils to ensure that each coil is height adjustable. In other embodiments, the number of the holes can be flexibly set, and the number of the holes is larger than the number of the coil turns or smaller than the number of the coil turns.
Referring to fig. 4, the information of the distance between the height adjustment device 100 and the adjustment control device 300 (i.e. the distance between the bottom of the height adjustment device 100 and the top of the fixing component 320 of the adjustment control device 300) is denoted as Ii1Where i refers to the ith coil. The initial value of the distance between the height adjustment device 100 and the adjustment control device 300 is denoted as Ii0That is, when the winding height of the coil is consistent with the design value, the distance between the height adjusting device 100 and the adjusting control device 300 is large or small. I is0Is the height value of the height adjustment device 100, I1The distance between the top of the hollow groove in the middle of the Y-shaped fixing component 320 and the top of the fixing component 320. Suppose the design height of the ith coil is hi0The actual height of the ith coil is hi1And the height of the insulating package of the reactor is h, the above parameters meet the following requirements: h is hi0+2(I0+Ii0+I1) Since the bottom and top of the reactor have the same inner epoxy encapsulation and bus structure, I0、Ii0、I1The sum of the three needs to be multiplied by 2.
When the ith coil sinks in the actual winding process, the actual height h of the coili1Will be greater than the lineRing design height hi0Distance I between height adjusting means 100 and adjusting control means 300i1Will be less than the design distance Ii0However, the height h of the insulation-containing envelope of the reactor remains unchanged during the winding process of the coil, and the distance detector 311 detects the distance I between the height adjusting device 100 and the adjusting control device 300i1Then, the distance value is transmitted to the upper computer 330 in an electric signal mode through cable transmission or wireless transmission, and the upper computer 330 transmits Ii0And Ii1And subtracting to obtain the sinking height of the coil. Then the upper computer 330 calls a corresponding control program, analyzes to obtain an adjusting signal and sends the adjusting signal to the controller 312, the controller 312 finally sends a driving signal according to the adjusting signal to drive the stepping motor to rotate, and the stepping motor drives the threaded pipe to rotate upwards Ii0-Ii1A distance of such a magnitude that the distance I between the height adjusting device 100 and the adjustment control device 300i1And design value Ii0Remains the same, thereby increasing the distance Ii1And the height of the coil is reduced, so that the problem of sinking during coil winding is avoided.
On the contrary, when the ith coil is lifted due to the conditions of lacking turns and the like in the actual winding process, the actual height h of the coil isi1Will be less than the coil design value hi0The upper computer 330 may drive the stepping motor to rotate downward by the controller 312 in a similar manner as described abovei1-Ii0A distance of such a magnitude that the distance I between the height adjusting device 100 and the adjustment control device 300i1And design value Ii0Remains the same, thereby reducing the distance Ii1And the height of the coil is increased, so that the problem of lifting during coil winding is avoided.
In the reactor coil adjusting system, the reactor coil adjusting system is arranged at the bottom of the coil of the reactor, the height adjusting device 100 is closely arranged at the bottom of the coil of the reactor, and when the coil sinks or rises, the height adjusting device 100 sinks or rises for a corresponding distance. At this time, the height between the height adjusting device 100 and the adjustment control device 300 will be changed due to the movable connection between the height adjusting device 100 and the adjustment control device 300. The adjusting and controlling device 300 only needs to control the height adjusting device 100 to move according to the height change, so that when the coil sinks or is lifted, the winding height can be timely reduced or increased, and further the winding height of the reactor coil is kept consistent with a design value.
Referring to fig. 8, a method for adjusting a reactor coil based on the reactor coil adjusting system includes: step S100, step S200, and step S300.
Step S100, obtaining distance information between the adjusting control device and the height adjusting device; step S200, obtaining a height adjusting value required when the winding height of the coil is consistent with a design value according to the distance information; and step S300, controlling the connecting device to drive the height adjusting device to move according to the height adjusting value so as to realize the winding height adjustment of the coil.
Specifically, the structure of the reactor coil adjusting system is as shown in the above embodiments and the accompanying drawings, in the solution of this embodiment, the coil of the reactor is wound as shown in fig. 1, and the bottom of the coil of the reactor refers to one of two opening surfaces formed by the cylindrical coil when the coil is wound to form a cylindrical shape, the opening surface being provided with the supporting cushion block. When the coil of the reactor is wound, a plurality of coils need to be wound outwards along the radial direction from the central axis, and the radius of the coil is larger towards the outside. The winding height of the coil is the height of the cylindrical shape, i.e. the distance between two open faces of the cylindrical coil.
The height adjusting device 100 is movably connected with the adjusting control device 300 through the connecting device 200, the height adjusting device 100 is attached to the bottom of the coil, when the coil of the reactor sinks or is lifted, the height adjusting device 100 correspondingly sinks or lifts under the action force of the sinking or lifting of the coil, and the sinking or lifting distance of the height adjusting device 100 is consistent with the sinking or lifting distance of the coil. Referring to fig. 3, in one embodiment, after the reactor coil adjusting system is fixedly disposed at the bottom of the coil, the distance between the adjusting control device 300 and the bus bar disposed at the top is fixed, and when the coil sinks or rises, the height adjusting device 100 moves along with the coil, so that the distance between the height adjusting device 100 and the adjusting control device 300 moves according to the height of the coil.
Therefore, in this embodiment, by detecting the distance information between the height adjusting device 100 and the adjusting control device 300, when the distance information changes, that is, the winding height of the coil is changed. If the distance information is reduced, the winding height of the coil is increased, and the coil sinks; if the distance information is increased, it indicates that the coil is lifted up due to a lack of turns or the like.
When the coil sinks or is lifted, the adjusting control device 300 detects distance information between the coil and the height adjusting device 100, then obtains a height adjusting value required when the winding height of the coil is adjusted to be consistent with a design value according to the distance information, finally generates a corresponding adjusting signal according to the height adjusting value, and controls the connecting device 200 to drive the height adjusting device 100 to move, so that the height adjusting operation of the coil is realized.
Referring to fig. 9, in one embodiment, step S200 includes step S210.
And step S210, performing difference analysis according to the initial value of the distance between the adjusting control device and the height adjusting device and the distance information to obtain a height adjusting value required when the winding height of the coil is consistent with a design value.
Specifically, the distance between the adjustment control device 300 and the bus bar disposed at the top is a fixed value, and when the winding height of the coil is consistent with the design value, since the height of the height adjustment device 100 is fixed, the distance between the height adjustment device 100 and the adjustment control device 300 is also kept at a fixed value, which is recorded as an initial distance value. When analyzing whether the coil sinks or rises, it is only necessary to compare whether the distance information between the height adjustment device 100 and the adjustment control device 300, which is obtained by real-time detection, changes from the initial distance value.
In one embodiment, step S300 includes: when the height adjusting value is larger than zero, the connecting device is controlled according to the height adjusting value to drive the height adjusting device to move towards the direction close to the coil, so that the winding height of the coil is reduced.
Specifically, if the height adjustment value is greater than zero, it means that the initial distance value is greater than the distance information (actually measured), which indicates that the distance between the height adjustment device 100 and the adjustment control device 300 is reduced due to the coil sinking, that is, the winding height of the coil is greater than the design value. Therefore, in this case, the adjusting control device 300 (specifically, the controller 312 or the upper computer 330) calls a corresponding control program, analyzes the driving signal required for decreasing the coil height (or increasing the distance between the height adjusting device 100 and the adjusting control device 300), and the driver 313 (specifically, the stepping motor) drives the connecting device 200 to rotate upward Ii0-Ii1A distance of such a magnitude that the distance I between the height adjusting device 100 and the adjustment control device 300i1And design value Ii0Remains the same, thereby increasing the distance Ii1And the height of the coil is reduced, so that the problem of sinking during coil winding is avoided.
In one embodiment, step S300 includes: when the height adjusting value is smaller than zero, the connecting device is controlled according to the height adjusting value to drive the height adjusting device to move towards the direction far away from the coil, so that the winding height of the coil is increased.
Specifically, if the height adjustment value is smaller than zero, it means that the initial distance value is smaller than the distance information (actually measured), which indicates that the distance between the height adjustment device 100 and the adjustment control device 300 is increased due to the coil lifting, that is, the winding height of the coil is smaller than the design value. Therefore, in this case, the adjusting control device 300 (specifically, the controller 312 or the upper computer 330) calls a corresponding control program, analyzes and obtains a driving signal required for increasing the coil height (or reducing the distance between the height adjusting device 100 and the adjusting control device 300), and the driver 313 (specifically, the stepping motor) drives the connecting device 200 to rotate downward Ii1-Ii0A distance of such a magnitude that the distance I between the height adjusting device 100 and the adjustment control device 300i1And design value Ii0Is maintained at oneThus reducing the distance Ii1And the height of the coil is increased, so that the problem of lifting during coil winding is avoided.
According to the reactor coil adjusting method, the reactor coil adjusting system is arranged at the bottom of the reactor coil, the height adjusting device 100 is arranged at the bottom of the reactor coil in a clinging manner, and when the coil sinks or rises, the height adjusting device 100 sinks or rises for a corresponding distance. At this time, the height between the height adjusting device 100 and the adjustment control device 300 will be changed due to the movable connection between the height adjusting device 100 and the adjustment control device 300. The adjusting and controlling device 300 only needs to control the height adjusting device 100 to move according to the height change, so that when the coil sinks or is lifted, the winding height can be timely reduced or increased, and further the winding height of the reactor coil is kept consistent with a design value.
