[0034] See also Figures 1 to 13 The embodiment of the present invention provides a processing technology for a transformer for measuring and powering a device, comprising the following steps: S1: Electromagnetic transformer 1 mold assembly.

[0035] S2: Casting to form a first fixed sealing part 10 encapsulating the electromagnetic transformer 1. Specifically, the first fixed sealing part 10 is formed with a first mounting hole 11 and a boss 12 facing the electromagnetic transformer 1.

[0036] S3: Electronic transformer 2 mold assembly.

[0037] S4: Casting to form a second fixed sealing part 20 that encapsulates the electronic transformer 2. Specifically, a second mounting hole 21 for docking with the first mounting hole 11 is formed on the second fixed sealing part 20; S5: Assemble the melting tube assembly 3.

[0038] S6: Assembling the transformer as a whole. Specifically, the step includes installing the melting tube assembly 3 in the first mounting hole 11 and the second mounting hole 21 , and fixing the first sealing portion 10 and the second sealing portion 20 .

[0039] Through the above scheme, the electromagnetic transformer 1 is cast and packaged to form the corresponding first fixed sealing part 10, and the electronic transformer 2 is cast and packaged to form the corresponding second fixed sealing part 20, so that the protection of the components of the electromagnetic transformer 1 and the components of the electronic transformer 2 can be guaranteed, and the first fixed sealing part 10 and the second fixed sealing part 20 are separately packaged, which can ensure the stability of the molding of each structure to a certain extent, avoid the mutual influence between the various structures when the electromagnetic transformer 1 and the electronic transformer 2 are molded, and reduce the difficulty of molding and casting; the first fixed sealing part 10 and the second fixed sealing part 20 formed by separate packaging, and the assembly of the separately assembled fuse tube assembly 3, that is, the first mounting hole 11 is formed on the first fixed sealing part 10, and the second mounting hole 21 is formed on the second fixed sealing part 20, and the fuse tube assembly 3 is installed in the first mounting hole 11 and the second mounting hole 21, and then the first fixed sealing part 10 and the second fixed sealing part 20 are fixed, which can further reduce the processing difficulty and facilitate the replacement of the fuse tube assembly 3. Furthermore, the first sealing part 10 and the second sealing part 20 are respectively packaged to form two independent components, the electronic transformer 2 and the electromagnetic transformer 1, which can be tested according to their respective product standards, thus solving the problem that the two components cannot be tested uniformly due to different test items.

[0040] Specifically, the electromagnetic mutual inductor 1 includes a coil assembly 13 , a fuse high voltage shielding net 14 , a fuse ground potential shielding net 15 and a side ground potential shielding net 16 .

[0041] It can be known that the side ground potential shielding net 16 has a relatively large area. At the same time, in order to avoid an excessively large assembly volume, the side ground potential shielding net 16 is usually designed to be thin. In order to avoid deformation of the side ground potential shielding net 16, in this embodiment, step S1 specifically includes: S1.1: Fix the coil assembly 13 on the mold.

[0042] S1.2: Fixed fuse ground potential shielding net 15.

[0043] S1.3: Fix the high-voltage shielding net 14 of the melting tube. Specifically, the high-voltage shielding net 14 of the melting tube includes a high-voltage shielding net 141 at the front end of the melting tube and a high-voltage shielding net 142 at the rear end of the melting tube. The high-voltage shielding net 141 at the front end of the melting tube and the high-voltage shielding net 142 at the rear end of the melting tube are respectively located at the two ends of the melting tube ground potential shielding net 15 and do not contact each other. The high-voltage shielding net 142 at the rear end of the melting tube is used to be connected to the melting tube assembly 3.

[0044] S1.4: Fix the side ground potential shielding net 16. Specifically, the side ground potential shielding net 16 is welded to the melting tube ground potential shielding net 15, and both ends are fixedly connected to the coil assembly 13.

[0045] This solution first installs the fused tube ground potential shielding net 15, then installs the side ground potential shielding net 16, and welds the upper end of the side ground potential shielding net 16 to the fused tube ground potential shielding net 15, and the two ends of the side ground potential shielding net 16 are fixedly connected to the coil assembly 13, which can ensure the stability of the installation of the side ground potential shielding net 16 and avoid its deformation. The two ends of the side ground potential shielding net 16 can be fixed to the coil assembly 13 by using a binding band.

[0046] Specifically, the coil assembly 13 includes an iron core 131, secondary insulating paper, a secondary winding coil, a primary insulating paper and a primary winding coil. Step S1.1 specifically includes: S1.1.1: Winding a secondary insulating paper, a secondary winding coil, a primary insulating paper and a primary winding coil on the iron core 131 in sequence to form the coil assembly 13 .

[0047] S1.1.2: Use a binding tape to fix the iron core 131 on the mold to fix the entire coil assembly 13.

[0048] It can be known that in order to achieve a better insulation effect and meet the high-voltage use of the current measuring and power supply integrated transformer, in this embodiment, the secondary insulation paper and the primary insulation paper are both made of PMP paper, and the thickness of the PMP paper (secondary insulation paper and primary insulation paper) is set to 0.1 mm. Among them, the winding thickness of the primary insulation paper is set to 10 mm, so that there is a 10 mm interval between the secondary winding coil and the primary winding coil.

[0049] Through the setting of secondary insulation paper and primary insulation, it is possible to meet the high-voltage use of this product and realize the positioning of the secondary winding coil and the primary winding coil, avoiding the problem of uneven gap control between the secondary winding coil and the primary winding coil caused by the flat copper rod used in the prior art; wherein, the binding tape is also an insulating material, and the method of fixing the iron core 131 with the binding tape can facilitate the operation of fixing the iron core 131, and the binding tape will eventually be formed in the first sealing part 10, and will not affect the use of the iron core 131.

[0050] It can be known that in this embodiment, two coil assemblies 13 are provided.

[0051] Furthermore, in order to achieve conductive connection of various internal structures of the electromagnetic mutual inductor 1 and connection between the electromagnetic mutual inductor 1 and external structures, in this embodiment, step S1 further includes: S1.5: Install the electromagnetic transformer conductive insert 17 according to the wiring principle design drawing of the integrated measurement and power supply transformer.

[0052] Specifically, the electromagnetic mutual inductor conductive insert 17 can be set as a copper insert, and the electromagnetic mutual inductor conductive insert 17 includes a first electromagnetic mutual inductor conductive insert 171, a second electromagnetic mutual inductor conductive insert 172 and a third electromagnetic mutual inductor conductive insert 173. Among them, there are a plurality of first electromagnetic mutual inductor conductive inserts 171, and the first electromagnetic mutual inductor conductive insert 171 is used to be welded and positioned with the melting tube ground potential shielding net 15 and the melting tube high voltage shielding net 14, and is welded and fixed on the mold synchronously with the melting tube ground potential shielding net 15 and the melting tube high voltage shielding net 14. The second electromagnetic mutual inductor conductive insert 172 includes an A-phase copper nut, a B-phase copper nut, and a C-phase copper nut, which are used to be connected to the output line of the secondary winding coil of the coil assembly 13. The third electromagnetic mutual inductor conductive insert 173 is installed on the high voltage shielding net 142 at the rear end of the melting tube, and then the third electromagnetic mutual inductor conductive insert 173 is used to fix the high voltage shielding net 142 at the rear end of the melting tube on the mold. Of course, in other embodiments, the high-voltage shielding net 141 at the front end of the melting tube may also be connected to the mold by using corresponding copper inserts, and the corresponding copper inserts may be provided according to actual needs.

[0053] It is worth noting that, in this embodiment, the copper insert can be used for conductive connection with various internal structures, and can also be used as an external interface of the transformer for connecting with external structures, and can be set according to the wiring principle design diagram of the transformer for measuring and power supply. And this setting facilitates the positioning and installation of the fuse high-voltage shielding net 14, so that the circular hole formed by it for accommodating the fuse assembly 3 is through-through, and the fuse assembly 3 can be disassembled and replaced from the front or back.

[0054] It can be known that, in this embodiment, three groups of the fuse assembly 3 are correspondingly provided, and correspondingly, three groups of the fuse high voltage shielding net 14, the fuse ground potential shielding net 15, the first electromagnetic mutual inductor conductive insert 171, the second electromagnetic mutual inductor conductive insert 172, and the third electromagnetic mutual inductor conductive insert 173 are also correspondingly provided. Among them, the third electromagnetic mutual inductor conductive insert 173 is used to connect the A, B, and C phases of the primary winding coil of the coil assembly 13 respectively.

[0055] In this embodiment, the electronic transformer 2 includes a power ring 22, a power module 23 corresponding to the power ring 22, and three groups of power rings 22 and power modules 23 corresponding to the fuse assembly 3 are arranged. The power ring 22 is arranged around the periphery of the fuse assembly 3 and is electrically connected to the power module 23 corresponding to the power ring 22 through a wire. The power module 23 can be connected to a voltage divider circuit. It can be known that the power ring 22 coincides with the central axis of the second mounting hole 21.

[0056] In this embodiment, step S3 includes: S3.1: Fix the power taking ring 22 and the power taking module 23 on the mold; S3.2: Connect the power taking ring 22 and its corresponding power taking module 23 through a wire; S3.3: According to the wiring principle design drawing of the integrated measuring and power supply transformer, install the electronic transformer conductive insert 24. Similarly, the electronic transformer conductive insert 24 can also be set as a copper insert, which can be used for conductive connection between internal structures and can also be used as an external interface of the transformer for connection with external structures. It can be set according to the wiring principle design drawing of the integrated measuring and power supply transformer.

[0057] In this embodiment, the melting tube assembly 3 includes a bolt 31, a nut 32, a melting tube claw 33 and a melting tube. Step S5 includes: S5.1: Install the nut 32 on one end of the bolt 31.

[0058] S5.2: Install the melting pipe claw 33 on the end surface of the nut 32 away from the bolt 31.

[0059] S5.3: Insert the melting tube 34 into the melting tube claw 33 to fix the melting tube 34 .

[0060] Specifically, the nut 32 is formed with a stepped groove, and the end of the bolt 31 is formed with a stepped portion. When installed, the stepped portion is inserted into the stepped groove to achieve mutual positioning of the bolt 31 and the nut 32. The fuse claw 33 and the end of the nut 32 away from the bolt 31 are pressed against the nut 32 and connected to the end of the bolt 31 by a screw 35, thereby achieving the fixation of the bolt 31, the nut 32 and the fuse claw 33.

[0061] In this embodiment, step S6 specifically includes: installing the fuse tube assembly 3 in the first mounting hole 11 and the second mounting hole 21, and connecting the fuse tube assembly 3 and the fuse tube high-voltage shielding net 14 (specifically, the fuse tube rear end high-voltage shielding net 142) through the electromagnetic mutual inductor conductive insert 17 (specifically, the third electromagnetic mutual inductor conductive insert 173). It also includes setting a silicone inner climbing umbrella 4 at the docking position of the first mounting hole 11 and the second mounting hole 21, and the silicone inner climbing umbrella 4 is arranged around the partial periphery of the fuse tube assembly 3; the silicone inner climbing umbrella 4 is partially inserted into the first mounting hole 11 and partially inserted into the second mounting hole 21. It also includes installing an insulating plugging cover 5 at the end of the second mounting hole 21 away from the first mounting hole 11.

[0062] It can be known that the first sealing part 10 cooperates with the insulating plug cover 5 to become a power supply that can be used alone, and different functions can be realized by combining parts and components for flexible use. In terms of structural design, the melting tube assembly 3 can be disassembled and replaced from the front or back to adapt to various boxes with front or rear doors, which is convenient for on-site maintenance and construction.

[0063] Specific Figure 8 Assemble in the Z direction as shown, the specific operation steps can be set as: S6.1: Fix the electromagnetic transformer 1.

[0064] S6.2: Install the fuse tube assembly 3 on the electromagnetic transformer 1. Specifically, three fuse tube assemblies 3 are respectively inserted into the corresponding first mounting holes 11, and the nuts 32 of the fuse tube assemblies 3 are threadedly connected with the corresponding third electromagnetic transformer conductive inserts 173.

[0065] S6.3: Install the silicone inner climbing parachute 4. Specifically, one end (partial area) of the silicone inner climbing parachute 4 is inserted into the first installation hole 11.

[0066] S6.4: docking the electromagnetic transformer 1 and the electronic transformer 2. Specifically, align the second mounting hole 21 with the corresponding first mounting hole 11, and move the electronic transformer 2 so that the end of the melting tube assembly 3 and the silicone inner climbing umbrella 4 away from the first mounting hole 11 is inserted into the second mounting hole 21.

[0067] S6.5: Use fasteners to fix the first sealing part 10 and the second sealing part 20. Specifically, the fasteners can be screws.

[0068] S6.6: Install the bottom plate 6. Specifically, align the notch on the bottom plate 6 with the boss 12, and then use fasteners to connect the bottom plate 6 and the first fixed sealing part 10 and the second fixed sealing part 20. It can be seen that the boss 12 is arranged opposite to the coil assembly 13 (relatively large in volume), which can reduce the volume of the first fixed sealing part 10 to a certain extent, thereby reducing the steps of the entire device. At the same time, the arrangement of the boss 12 can also realize the positioning and installation of the bottom plate 6. The fact that the bottom plate 6 is connected to the first fixed sealing part 10 and the second fixed sealing part 20 at the same time can further increase the stability of the connection.

[0069] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
