Description

Technical Field

[0001] This utility model relates to the field of voltage transformer technology, specifically a 110kV low magnetic flux density electromagnetic voltage transformer. Background Technology

[0002] 110kV is a high-voltage level, mainly used for regional power grid transmission and power supply to large industrial enterprises. Its voltage range is typically between 100kV and 120kV, suitable for long-distance transmission and large-scale power distribution. In power systems, 110kV equipment usually requires insulation levels of 126kV to ensure safety and reliability. Furthermore, the design and load conditions of 110kV substations also affect their application and operation, and voltage transformers are installed to ensure the safe operation of the circuits.

[0003] Chinese Utility Model Patent Publication No. CN209641508U discloses a voltage transformer, including a casting body, a mounting plate, and an internal body. The neutral point of the secondary winding is grounded, creating a high impedance between the neutral point and the ground. When a ground fault occurs in the power grid, this neutral point is locked and difficult to move, effectively reducing power system resonance. The middle terminal of the primary winding is connected to terminal B (measuring instrument). Regardless of whether a ground fault occurs in the power system, the middle terminal of the primary winding can continuously and evenly provide the three-phase voltage measuring instrument. The middle terminal of the primary winding is connected in series with the two side leads of the primary winding, which are respectively connected to phases A and C. Even if a connection fault occurs in either phase A or C, the middle terminal of the primary winding can still measure the degree of fault in that phase, increasing practicality.

[0004] While the aforementioned voltage transformers can reduce the probability of phase failures during use, they lack mechanisms for easy installation and disassembly, making installation and maintenance difficult and reducing user efficiency. Furthermore, the installed lines cannot be adequately secured, increasing the probability of line contact and loosening, which can affect stable line operation and reduce the practicality of the voltage transformers. Therefore, we propose a 110kV low magnetic density electromagnetic voltage transformer. Summary of the Invention

[0005] In view of the shortcomings of the prior art, this utility model provides a 110kV low magnetic density electromagnetic voltage transformer to solve the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a 110kV low magnetic density electromagnetic voltage transformer, including an installation component, a connection component, and a positioning component. The installation component includes a base, and the top of the base has an installation groove. The connecting assembly includes a housing, and an elastic element is fixedly fitted onto the outer wall of the housing; The positioning assembly includes a spool extending through the outer wall of the housing. A sealing plate is provided on the outer wall of the spool. A connecting shell extends through the outer wall of the spool. A groove is formed in the middle of the connecting shell. A sleeve is fixedly fitted onto the inner wall of the connecting shell. A rotating plate is rotatably connected to the inner wall of the sleeve. An arc-shaped groove is formed on the outer wall of the rotating plate. A limiting rod is slidably connected to the inner wall of the arc-shaped groove. A limiting plate is fixedly fitted onto the side wall of the rotating plate away from the spool. A knob is provided on the inner wall of the limiting plate. A movable groove is formed on the outer wall of the knob. A positioning ring is fixedly fitted onto the end of the sleeve away from the spool. A slot is formed on the end of the positioning ring away from the spool. A clamping plate is rotatably connected to the end of the limiting rod away from the positioning ring. A second magnet is provided on the side wall of the knob near the spool, and a first magnet is correspondingly provided on the second magnet.

[0007] Through the above technical solution, by setting up the installation components, connection components, base, and mounting groove structure, the user can press the elastic element during the use of the voltage transformer to deform the elastic element and pass through the mounting groove, thereby ensuring that the elastic element will return to its original position and hook onto the inner wall of the mounting groove after the user releases it. This achieves the effect of quickly fixing the housing to the base, thereby improving the user's assembly and maintenance efficiency of the voltage transformer.

[0008] Preferably, the shape of the mounting groove is adapted to the shape of the elastic element, and the housing is fixedly connected to the base through the elastic element.

[0009] Through the above technical solution, the base and elastic component structure reduces the probability of the housing separating from the base after being fixed by using the elastic component to hook the mounting groove during the use of the voltage transformer. This effectively stabilizes the connection structure between the housing and the base, thereby ensuring the stability of the voltage transformer after assembly.

[0010] Preferably, the number of elastic elements is several, and the several elastic elements are evenly distributed along the outer wall of the shell.

[0011] Through the above technical solution, by setting several elastic components, the voltage transformer can be fixed to the housing after assembly, thereby reducing the probability of loosening after installation and further improving the stability of the voltage transformer after assembly.

[0012] Preferably, the inner wall of the movable groove is slidably connected to the inner wall of the limiting plate, the inner wall of the limiting plate is provided with a groove, and the inner wall of the groove is fixedly assembled with the outer wall of the magnet, the inner wall of the limiting plate is provided with a limiting groove, and the inner wall of the limiting groove is slidably connected to the outer wall of the knob.

[0013] Through the above technical solution, the groove and magnet structure allows the user to rotate the limiting plate by pulling the knob during use, thereby adjusting the distance between the clamping plates. This facilitates the user to pass wires of different diameters through the rotating plate and clamp the wires. Then, the repulsive force fixes the knob to the positioning ring, thereby reducing the probability of the wires becoming loose after installation, reducing the probability of short circuits, ensuring the stability of the circuit during operation, and improving the practicality of the voltage transformer.

[0014] Preferably, the first magnet and the second magnet are like-pairs and repel each other, the number of the second magnet is two, and the two second magnets are symmetrically distributed along the outer wall of the knob.

[0015] With the above technical solution, the use of magnet one and magnet two structures allows users to pass the wires through the clamping plate during installation, thus clamping the wires. After clamping, the user can loosen the knob, which is then fixedly connected to the positioning ring by the protrusion. This reduces the likelihood of the clamping plate loosening during clamping, ensuring the clamping effect on the wires. It also makes it easier for users to pass wires of different diameters through the clamping plate to complete the assembly, expanding the applicability of the voltage transformer.

[0016] Preferably, the outer wall of the knob is fixedly fitted with a protrusion, and the shape of the protrusion matches the shape of the slot, and the rotating plate is fixedly connected to the positioning ring through the protrusion.

[0017] Through the above technical solution, the protrusion and slot structure allows the voltage transformer to use the protrusion to fix the knob during use, thereby achieving the effect of clamping the line firmly and ensuring the normal use of the voltage transformer.

[0018] Compared with the prior art, this utility model provides a 110kV low magnetic flux density electromagnetic voltage transformer, which has the following beneficial effects: 1. This 110kV low magnetic density electromagnetic voltage transformer, through its installation components, base, mounting slot, housing, and elastic element structure, allows the user to deform the elastic element by pressing it during use. This allows the elastic element to pass through the mounting slot and hook onto the inner wall of the mounting slot when the user releases the elastic element, achieving a quick connection between the housing and the base. This facilitates the user's assembly and disassembly of the voltage transformer, improving the efficiency of assembly and maintenance.

[0019] 2. This 110kV low magnetic density electromagnetic voltage transformer, through its structure of slots, coils, sealing plates, connecting shells, wire grooves, sleeves, rotating plates, arc-shaped grooves, movable grooves, magnet one, and magnet two, allows the user to pull the knob after installation so that the protrusion on the knob disengages from the slot. This facilitates the user's rotation of the knob, enabling the clamping plate to hold lines of different diameters, thereby ensuring the stability of the line during operation and improving the applicability of the voltage transformer. At the same time, the repulsive force between magnet one and magnet two reduces the probability of the clamping plate loosening when holding the line, thus improving the practicality and stability of the voltage transformer.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-5As shown, the 110kV low magnetic density electromagnetic voltage transformer provided by this utility model includes an installation component 1, a connection component 2, and a positioning component 3. The installation component 1 includes a base 101, and the top of the base 101 is provided with an installation groove 102. The connecting component 2 includes a housing 201, and an elastic element 202 is fixedly assembled on the outer wall of the housing 201; The positioning assembly 3 includes a bobbin 301 penetrating the outer wall of the housing 201. A sealing plate 302 is provided on the outer wall of the bobbin 301. A connecting shell 303 penetrates the outer wall of the bobbin 301. A wire groove 304 is formed in the middle of the connecting shell 303. A sleeve 305 is fixedly fitted onto the inner wall of the connecting shell 303. A rotating plate 306 is rotatably connected to the inner wall of the sleeve 305. An arc-shaped groove 307 is formed on the outer wall of the rotating plate 306. A limit rod 308 is slidably connected to the inner wall of the arc-shaped groove 307. The rotating plate 306 is located away from the bobbin 301. A limiting plate 310 is fixedly mounted on the side wall. A knob 311 is provided on the inner wall of the limiting plate 310. A movable groove 314 is provided on the outer wall of the knob 311. A positioning ring 312 is fixedly mounted on the end of the sleeve 305 away from the spool 301. A slot 313 is provided on the end of the positioning ring 312 away from the spool 301. A clamping plate 309 is rotatably connected to the end of the limiting rod 308 away from the positioning ring 312. A magnet 316 is provided on the side wall of the knob 311 near the spool 301. A magnet 315 is correspondingly provided on the magnet 316.

[0024] The advantage is that, through the structure of the mounting component 1, connecting component 2, base 101, and mounting groove 102, the user can press the elastic element 202 during use, causing the elastic element 202 to deform and pass through the mounting groove 102. This ensures that after the user releases the elastic element 202, it will return to its original position and hook onto the inner wall of the mounting groove 102, thereby achieving the effect of quickly fixing the housing 201 to the base 101, thus improving the user's assembly and maintenance efficiency of the voltage transformer.

[0025] Specifically: the shape of the mounting groove 102 is adapted to the shape of the elastic element 202, and the housing 201 is fixedly connected to the base 101 through the elastic element 202.

[0026] The advantage is that, through the structure of the base 101 and the elastic element 202, the probability of the housing 201 separating from the base 101 after being fixed is reduced by using the elastic element 202 to hook the mounting groove 102 during the use of the voltage transformer. This achieves the effect of stabilizing the connection structure between the housing 201 and the base 101, thereby ensuring the stability of the voltage transformer after assembly.

[0027] Specifically, there are several elastic elements 202, and all of them are evenly distributed along the outer wall of the shell 201.

[0028] The advantage is that by setting up a structure of several elastic elements 202, the voltage transformer can be fixed to the housing 201 after assembly, thereby reducing the probability of the housing 201 becoming loose after installation and further improving the stability of the voltage transformer after assembly.

[0029] Specifically: the inner wall of the movable groove 314 is slidably connected to the inner wall of the limiting plate 310, the inner wall of the limiting plate 310 is provided with a groove, and the inner wall of the groove is fixedly assembled with the outer wall of the magnet 315. The inner wall of the limiting plate 310 is provided with a limiting groove, and the inner wall of the limiting groove is slidably connected to the outer wall of the knob 311.

[0030] The advantage is that, through the groove and magnet 315 structure, the user can rotate the limiting plate 310 by pulling the knob 311 during use, thereby adjusting the distance between the clamping plates 309. This makes it easy for the user to pass wires of different diameters through the rotating plate 306 and clamp the wires. Then, the repulsive force fixes the knob 311 to the positioning ring 312, thereby reducing the probability of the wires becoming loose after installation, reducing the probability of short circuits, ensuring the stability of the circuit during operation, and improving the practicality of the voltage transformer.

[0031] Specifically: Magnet 1 315 and Magnet 2 316 repel each other because they are of the same polarity. There are two Magnet 2 316, and both Magnet 2 316 are symmetrically distributed along the outer wall of the knob 311.

[0032] The advantage is that, through the structure of magnet 315 and magnet 316, the user can pass the wire through the clamping plate 309 during installation, so that the wire can be clamped. After the clamping operation is completed, the user can loosen the knob 311, so that the knob 311 is fixedly connected to the positioning ring 312 by the protrusion, thereby reducing the possibility of the clamping plate 309 loosening during the clamping process, thus ensuring the clamping effect of the clamping plate 309 on the wire, and making it easier for the user to pass wires of different diameters through the clamping plate 309 to complete the assembly operation, thereby improving the applicability of the voltage transformer.

[0033] Specifically: the outer wall of the knob 311 is fixedly fitted with a protrusion, and the shape of the protrusion is adapted to the shape of the slot 313, and the rotating plate 306 is fixedly connected to the positioning ring 312 through the protrusion.

[0034] The advantage is that, through the structure of the protrusion and slot 313, the voltage transformer can use the protrusion to fix the knob 311 during use, thereby achieving the effect of the clamp 309 firmly clamping the line, thus ensuring the normal use of the voltage transformer.

[0035] Working principle: When assembling the voltage transformer, the user can first press the elastic element 202 to deform and bend it, allowing it to pass through the mounting groove 102. When the elastic element 202 returns to its original position, it can hook onto the inner wall of the mounting groove 102, facilitating assembly and maintenance and improving the user's efficiency in assembling and disassembling the voltage transformer. After assembly, when installing the wiring, the user can rotate the knob 311 to rotate the clamping plate 309, allowing wires of different diameters to pass through it. This improves the adaptability and application range of the voltage transformer. The clamping plate 309 also holds the wires tightly against the insulation layer, and the locking of the knob 311 by the protrusion reduces the probability of the clamping plate 309 loosening during clamping, thus improving the practicality of the voltage transformer and the clamping effect on the wires.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
