Description

Technical Field

[0001] This utility model relates to the field of current transformer technology, and more specifically, to a combined current transformer that is easy to assemble and splice. Background Technology

[0002] Instrument transformers include current transformers and voltage transformers. The main function of instrument transformers is to proportionally convert high voltage or large current into standard low voltage or standard small current, so as to realize the standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment.

[0003] Current transformers and voltage transformers are often used together, and installing them simultaneously can occupy a significant amount of installation space. If current transformers and voltage transformers could be quickly assembled, the installation space occupied by the transformer platform could be effectively reduced. Furthermore, since both current transformers and voltage transformers are bolted for installation, the disassembly and assembly of multiple sets of transformers is relatively slow. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a combined current transformer that is easy to assemble and splice, aiming to improve the problem that current transformers and voltage transformers occupy a lot of installation space and have a slow installation speed when installed at the same time.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a conveniently assembled combined current transformer, including a main body for current transformer assembly and a fixing buckle assembly.

[0007] The main body of the transformer assembly includes a current transformer and a voltage transformer. The current transformer has a base at its bottom, and the base has mounting holes.

[0008] The fixing buckle assembly includes a base, a bracket, and a plug. The two bases are respectively fixed on both sides of the current transformer, and the base is provided with a hanging groove. The bracket is installed on one side of the voltage transformer, and the bottom buckle of the bracket passes through the hanging groove. The bottom of the bracket is provided with a slot, and the plug is inserted into the slot.

[0009] In one embodiment of this utility model, a gasket is provided on the mounting holes on both sides of the base, and a V-shaped opening is provided on the side of the gasket.

[0010] In one embodiment of this utility model, both the insert and the slot are mating pyramidal structures.

[0011] In one embodiment of this utility model, a limiting groove is provided at the bottom of the base, and the top of the insert block is inserted into the limiting groove.

[0012] In one embodiment of this utility model, the fixing buckle assembly further includes a pull ring, which is disposed at one end of the insert block.

[0013] In one embodiment of this utility model, the pull ring end is provided with a threaded rod, and the insert end is provided with a threaded hole that is screwed into the threaded rod.

[0014] In one embodiment of this utility model, both sides of the bottom end of the bracket are chamfered.

[0015] In one embodiment of this utility model, the gasket has a U-shaped structure.

[0016] The beneficial effects of this utility model are as follows: This utility model provides a conveniently assembled combined transformer through the above design. The bottom end of the bracket on the side of the voltage transformer passes through the mounting groove on the side of the current transformer's base. A plug is then inserted horizontally into the slot, locking the bracket and base together. This stably fixes the voltage transformer to the side of the current transformer, enabling quick assembly and disassembly of the current transformer and voltage transformer. Since the voltage transformer does not require bolts to be fixed to the same mounting surface as the current transformer, the usable surface area is reduced; even a smaller surface area can accommodate the assembled current and voltage transformers.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example

[0027] Please see Figures 1-6 This utility model provides a convenient assembly of combined current transformers, including a current transformer assembly body 10 and a fixing buckle assembly 20.

[0028] The voltage transformer 120 can be quickly installed on the outside of the transformer assembly body 10 through the cooperation of the transformer assembly body 10 and the fixing buckle assembly 20. This not only makes the installation fast but also saves installation space.

[0029] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 The main body 10 of the instrument transformer assembly includes a current transformer 110 and a voltage transformer 120. A base 130 is provided at the bottom of the current transformer 110, and mounting holes are provided on the base 130. The fixing buckle assembly 20 includes a bracket 210, a hanger 220, and a plug 240. Two brackets 210 are respectively fixed to both sides of the current transformer 110, and a hanging groove 211 is provided on the bracket 210. The hanger 220 is installed on one side of the voltage transformer 120, and the bottom hook of the hanger 220 passes through the hanging groove 211. A slot 221 is provided at the bottom of the hanger 220, and the plug 240 is inserted into the slot 221.

[0030] The base 130 at the bottom of the current transformer 110 is fixed to the mounting platform by bolts. Voltage transformers 120 can be installed on both sides of the current transformer 110. The bottom end of the bracket 220 on the side of the voltage transformer 120 passes through the hanging groove 211 of the side bracket 210 of the current transformer 110. An insert 240 is horizontally inserted into the slot 221, locking the bracket 220 and the bracket 210 together, thus stably fixing the voltage transformer 120 to the side of the current transformer 110. This allows for quick assembly and disassembly of the current transformer 110 and voltage transformer 120. Since the voltage transformer 120 does not need to be fixed to the same mounting platform as the current transformer 110 using bolts, the usable platform area is reduced; even a smaller platform can accommodate the assembled current transformer 110 and voltage transformer 120.

[0031] For specific settings, please refer to Figure 2 Gaskets 140 are provided on the mounting holes on both sides of the base 130, and V-shaped openings 150 are provided on the sides of the gaskets 140. The V-shaped openings 150 make the gaskets 140 more flexible and the bolts installed on the base 130 more stable.

[0032] For further details, please refer to Figure 5 and Figure 6 Both the insert 240 and the slot 221 are mating pyramidal structures. A limiting groove 212 is provided at the bottom of the base 210, and the top of the insert 240 is inserted into the limiting groove 212. The limiting groove 212 is designed to simultaneously engage the insert 240 with both the base 210 and the hanger 220, making the base 210 and hanger 220 more stable after the insert 240 is inserted.

[0033] Specifically, the fixing buckle assembly 20 also includes a pull ring 250, which is disposed at one end of the insert block 240. The pull ring 250 has a threaded rod 260 at its end, and the insert block 240 has a threaded hole 241 at its end that engages with the threaded rod 260. The insert block 240 facilitates the removal of the insert block 240 from inside the slot 221.

[0034] In its specific design, the bottom two sides of the bracket 220 are chamfered to facilitate its insertion into the hanging slot 211. The gasket 140 has a U-shaped structure.

[0035] The working principle of this conveniently assembled current transformer is as follows: During use, the base 130 at the bottom of the current transformer 110 is fixed to the mounting platform using bolts. Voltage transformers 120 can be installed on both sides of the current transformer 110. The bottom end of the bracket 220 on the side of the voltage transformer 120 passes through the hanging groove 211 of the side bracket 210 of the current transformer 110. The insert 240 is then horizontally inserted into the slot 221, locking the bracket 220 and the bracket 210 together. This stably fixes the voltage transformer 120 to the side of the current transformer 110, allowing for quick assembly and disassembly of the current transformer 110 and voltage transformer 120. Since the voltage transformer 120 does not require bolts to be fixed to the same mounting platform as the current transformer 110, the usable platform area is reduced; even a smaller platform can accommodate the assembled current transformer 110 and voltage transformer 120.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
