Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of transformers and relates to a high-power, high-frequency and high-voltage dry-type transformer for a novel ozone generator. Background Art
[0002] Ozone is a light blue gas with a special smell and strong oxidizing properties. It can kill and disinfect all kinds of bacteria, fungi, viruses, etc. It is widely used, but because of its easy decomposition and difficulty in storage, it often needs to be produced on-site using an ozone generator.
[0003] The high-power, high-frequency, and high-voltage transformer used in the new ozone generator is a special transformer designed for the ozone generator. However, the transformers currently produced in China generally have disadvantages such as large size, low reliability, and low single-unit capacity. In particular, the transformer is a key supporting device for the ozone generator. Its shell-type magnetic core is restricted by the process and cannot be produced in large sizes, which in turn affects the single-unit capacity of the transformer. At this time, it is often necessary to increase the number of parallel machines to meet the capacity requirements. Utility Model Content
[0004] The utility model aims to solve the problem in the prior art that the special transformer used in the ozone generator is limited by the manufacturing process of the shell-type magnetic core and cannot produce a large-size, large-magnetic-flux iron core, thereby limiting the capacity of the transformer unit.
[0005] In order to achieve the above-mentioned purpose, the present application proposes a new type of high-power, high-frequency and high-voltage dry-type transformer for an ozone generator, including: an iron core, a coil wound around the iron core and a shell installed outside the iron core and the coil, the iron core includes a core-type magnetic core, an upper clamp, a lower clamp and a clamping screw. In order to install and fix the core-type magnetic core, an upper clamp and a lower clamp are arranged on the upper and lower sides of the core-type magnetic core, and the clamping screw is passed through the threaded holes on the upper clamp and the lower clamp and then tightened and installed with a nut. The core-type magnetic core includes a core column magnetic core and a yoke magnetic core, and yoke magnetic cores are horizontally installed at both ends of the two vertically placed core column magnetic cores.
[0006] The novel high-power, high-frequency, and high-voltage dry-type transformer for the ozone generator of the present application changes the shell-type magnetic core into a core-type magnetic core. Since the core-type magnetic core is spliced by pressed magnetic strips according to the designed size, and the processing technology of the magnetic strips can achieve large-size production, the core-type magnetic core spliced by the magnetic strips can also achieve the performance of large magnetic flux, thereby realizing the improvement of the single-unit capacity of the transformer.
[0007] Furthermore, in order to enhance the insulation performance between the clamping screw and the coil, the clamping screw is half-wrapped with imide tape and is sheathed with a self-extinguishing tube.
[0008] The coil includes: a frame wrapped around the core column magnetic core, a primary coil wrapped around the frame, a secondary coil wrapped around the outside of the primary coil, an air duct arranged between the primary coil and the secondary coil layer, and a conductive bar with one end connected to the lead of the primary coil and the other end extending out of the shell.
[0009] Furthermore, the frame is composed of four insulating boards assembled according to the designed size into a rectangular frame without upper and lower bottoms, and the boards are firmly bonded with epoxy glue.
[0010] Furthermore, the skeleton is provided, which not only enhances the insulation performance between the primary coil and the iron core, but also serves as a supporting structure to limit the shape and size of the primary coil during the coil winding process.
[0011] Furthermore, in order to enhance the insulation performance between the outer surface of the frame and the coil and prevent creepage, insulating glue paper is wrapped on the outer surface of the frame to isolate the primary coil.
[0012] Furthermore, in order to enhance the insulation performance between coil layers, the layers of the primary coil are isolated with insulating dotted paper, and the layers of the secondary coil are isolated with double-layer composite insulating paper.
[0013] Furthermore, the lead wire of the primary coil is welded to the end of the conductive bar by argon arc welding, the other end of the conductive bar extends out of the shell, and the conductive bar and the lead wire are wrapped with imide paper and a self-extinguishing tube to enhance the insulation performance of the connection between the lead wire and the conductive bar.
[0014] The shell comprises a shell, a fan installed on the upper inner surface of the shell, a foot installed between the lower inner surface of the shell and the lower clamp by bolts, an insulator installed on the side wall of the shell and a connecting row installed between adjacent insulators.
[0015] Furthermore, the fan installed on the upper part of the shell blows air upward, which can effectively bring the heat generated by the transformer out of the shell, thereby completing the heat dissipation of the transformer.
[0016] Furthermore, the two feet are installed on the lower inner surface of the shell according to the track gauge, and several holes are opened on the feet. The parallel transformers can be installed on the feet in sequence according to actual conditions, and the installation holes on the lower clamp are the same as the track gauge of the feet.
[0017] Furthermore, the insulator is installed on the side wall of the shell, and the lead-out end of the secondary coil is connected to one end of the insulator by argon arc welding, and the lead-out end is wrapped with imide paper and a self-extinguishing tube.
[0018] Furthermore, in order to facilitate the adjustment of the gear position of the transformer, a connecting row is installed between the insulators.

The present application discloses a novel high-power, high-frequency, and high-voltage dry-type transformer for an ozone generator, wherein the core of the transformer is a core-type structure, and the core-type structure is formed by splicing pressed magnetic strips according to the designed size. The pressed magnetic strips are larger in size than the shell-type magnetic core, thereby avoiding the problem of being limited by the smaller size made by the existing domestic process, thereby limiting the single-unit capacity of the transformer.
[0021] 2. The present application discloses a novel high-power, high-frequency, and high-voltage dry-type transformer for an ozone generator, which achieves the purpose of reducing the size of the transformer, improving product reliability, and increasing the capacity of a single machine, thereby effectively reducing the number of transformers in parallel in the ozone generator and reducing the space occupied by the transformer.
[0022] 3.

[0034] The following will be combined with the attached Figures 1 to 6 The embodiments of the technical solution of the present application are described in detail. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application. In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.
[0035] like Figures 1 to 6 The present invention illustrates a novel high-power, high-frequency, and high-voltage dry-type transformer for an ozone generator. The high-power, high-frequency, and high-voltage dry-type transformer comprises an iron core 1, a coil 2 wound around the iron core 1, and a shell 3 installed outside the iron core 1 and the coil 2. The iron core 1 comprises a core-type magnetic core 11, an upper clamp 12 and a lower clamp 13 installed on the upper and lower sides of the core-type magnetic core 11, and a clamping screw 14 is installed by tightening a nut through threaded holes on the upper clamp 12 and the lower clamp 13. The core-type magnetic core 11 comprises a core column magnetic core 111 and a yoke magnetic core 112, and yoke magnetic cores 112 are horizontally installed at both ends of the two vertically placed core column magnetic cores 111.
[0036] In one embodiment of the present application, the iron core 1 is used to provide a magnetic field path for the transformer. When the transformer starts working, the core column core 111 in the iron core 1 enables the magnetic field to pass through the coil 2 inside it more concentratedly, thereby improving the transmission efficiency of the transformer. The coil 2 is used to provide an electric field path for the transformer. When the transformer starts working, current is passed through the coil 2 to generate an induced electromotive force. By changing the magnetic field in the transformer, the coil 2 can change its output voltage and achieve voltage increases and decreases.
[0037] In the prior art, the core 1 is a shell-type magnetic core, and its conventional manufacturing method is to press and form it through a mold, and then superimpose or stack the individually pressed magnetic core units together to form a larger, stronger or magnetic core assembly with specific performance. Due to the limitations of domestic process levels, the size of the shell-type magnetic core that can be manufactured by this method is difficult to increase, which in turn limits the single-unit capacity of the transformer.
[0038] In this embodiment, since the iron core 1 is transformed from a shell-type magnetic core to a core-type magnetic core 11, whose structure includes a core column magnetic core 111 and a yoke magnetic core 112, the core-type magnetic core 11 can be manufactured by splicing the pressed magnetic strips according to the designed size, and the size of the magnetic strips is not limited by the process level, so a larger iron core 1 can be manufactured, thereby achieving a larger magnetic flux, which significantly improves the single-unit capacity of the transformer and solves the problem that the traditional shell-type magnetic core cannot provide a larger magnetic flux.
[0039] Continue to refer to Figure 1 In a further embodiment, in order to enhance the insulation performance between the clamping screw and the coil, the clamping screw 14 is half-wrapped with imide tape and is covered with a self-extinguishing tube. The self-extinguishing tube can also play a flame retardant role after a transformer fails and catches fire.
[0040] Further, continue to refer to Figure 1 , Figure 3 The coil 2 includes: a skeleton 21 wound on the core column magnetic core 111, a primary coil 22 wound on the skeleton 21, a secondary coil 23 wound outside the primary coil 22, an air duct 24 arranged between the primary coil 22 and the secondary coil 23, and a conductive bar 25 with one end connected to the lead of the primary coil 22 and the other end extending out of the housing 3.
[0041] In one embodiment of the present application, the skeleton is composed of four insulating plates spliced and installed according to the designed size into a rectangular frame without upper and lower bottoms, and the plates are firmly bonded with epoxy glue. The skeleton is provided, which not only enhances the insulation performance between the primary coil and the iron core, but also serves as a supporting structure to limit the shape and size of the primary coil during the coil winding process.
[0042] Furthermore, in order to enhance the insulation performance between the outer surface of the frame and the coil and prevent creepage, an insulating glue paper is wrapped on the outer surface of the frame 21 to isolate the primary coil 22 .
[0043] Furthermore, in order to enhance the insulation performance between coil layers, the layers of the primary coil 22 are isolated with insulating dotted paper, and the layers of the secondary coil 23 are isolated with double-layer composite insulating paper.
[0044] Furthermore, the lead wire of the primary coil is welded to the end of the conductive bar by argon arc welding, the other end of the conductive bar extends out of the shell, and the conductive bar and the lead wire are wrapped with imide paper and a self-extinguishing tube to enhance the insulation performance of the connection between the lead wire and the conductive bar.
[0045] Furthermore, the air duct is arranged between the layers of the coil. When the transformer is working, the heat generated by the wires in the coil can be dissipated into the air through the air duct, and the air circulation is further driven by the fan to achieve the purpose of heat dissipation.
[0046] The housing 3 includes a housing 31, a fan 32 installed on the upper inner surface of the housing 31, a foot 33 installed between the lower inner surface of the housing 31 and the lower clamp 13 by bolts, an insulator 34 installed on the side wall of the housing 31, and a connecting row 35 installed between adjacent insulators 34. Furthermore, the fan installed on the upper part of the housing blows air upward, and the heat generated by the transformer is dissipated from bottom to top. The heat collected at the top of the housing can be effectively taken out of the housing through the rotation of the fan blades, thereby completing the heat dissipation of the transformer.
[0047] Furthermore, the two feet are installed on the lower inner surface of the shell according to the track gauge, and several holes are opened on the feet. The parallel transformers can be installed on the feet in sequence according to actual conditions, and the installation holes on the lower clamp are the same as the track gauge of the feet.
[0048] Furthermore, the insulator is installed on the side wall of the shell, and the lead-out end of the secondary coil is connected to one end of the insulator by argon arc welding, and the lead-out end is wrapped with imide paper and a self-extinguishing tube.
[0049] Furthermore, in order to facilitate the adjustment of the gear position of the transformer, a connecting bar is installed between the insulators. When gear shifting is required, the connecting bar can be installed between the required gear positions to complete the gear shifting.
[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
