Description

TECHNICAL FIELD

[0001] The utility model relates to the field of power equipment, especially to a three-in-one current transformer. BACKGROUND

[0002] In the operation and monitoring process of the power system, the three-in-one current transformer plays a crucial role, which can realize the measurement and monitoring of multiple current parameters at the same time, and provides key data support for the stable and safe operation of the power system.

[0003] However, the current three-in-one current transformer has some problems to be solved in actual installation. Among them, the assembly plate relied on during installation is usually designed in an integrated structure with the transformer. Although this integrated design ensures the integrity of the structure to some extent, it brings serious drawbacks. In actual installation scenarios, due to the different layouts of power equipment, the size, shape of installation space and the positional relationship of other equipment around are complex and changeable. However, because the assembly plate and the transformer are fixed as a whole, the position cannot be flexibly adjusted according to actual installation requirements, resulting in that in many cases, the three-in-one current transformer is difficult to be accurately installed to the ideal position. For example, due to the position limitation of the assembly plate, it cannot adapt to the installation space with special shape, etc. This undoubtedly greatly reduces the applicability of the three-in-one current transformer in different installation environments, and increases the installation difficulty and cost. SUMMARY

[0004] The utility model discloses in view of the deficiency in the prior art, through the cooperation of the assembly part and the locking assembly in the mounting frame, using the design of the fixed shaft rod and the locking sleeve, the position of the assembly part can be flexibly adjusted according to the actual installation space and requirements. When adjusted to the appropriate position, tighten the locking sleeve to firmly fix the assembly part, which is simple and convenient to operate, improves the flexibility and convenience in the installation process, greatly reduces the installation difficulty caused by the installation position limitation, and saves the installation time and labor cost.

[0005] In order to solve the above technical problems, the utility model discloses the following technical scheme, which effectively solves the poor applicability of the three-in-one current transformer in different installation environments.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A three-in-one current transformer, comprising: a current transformer body;

[0008] An assembly part is symmetrically arranged at both ends of the current transformer body, and a movable plate is connected to the assembly part;

[0009] The mounting frame is provided with an inner mounting groove on both sides, and the movable plate is connected to the corresponding position inside the inner mounting groove through the locking assembly.

[0010] Preferably, the locking assembly comprises a plurality of fixed shafts and locking sleeves, the fixed shafts are connected to the horizontal and vertical directions of the inner wall of the inner mounting groove respectively, the movable plate is sleeved on the fixed shaft along the opening of the inner mounting groove, and one end of the fixed shaft penetrating the assembly part is provided with a thread, and the thread is connected with the locking sleeve through thread rotation.

[0011] Preferably, the outer part of the fixed shaft is sleeved with a rod sleeve for stabilization.

[0012] Preferably, the assembly part is provided with a first preset hole at each corner.

[0013] Preferably, the contact surface of the bottom of the assembly part is provided with a second protruding piece, and the second protruding piece is designed of rubber material.

[0014] Preferably, the outer periphery of the bottom of the assembly part is provided with a positioning groove, and the second protruding piece is correspondingly clamped in the inner part of the positioning groove.

[0015] Preferably, the assembly part is glued with a first protruding layer on the surface in contact with the mounting frame.

[0016] Preferably, the mounting frame is provided with a plurality of second preset holes at both ends, and the second preset holes are locked through fastening bolts between the current transformer body.

[0017] Preferably, the lower end of the outer periphery of the current transformer body is provided with a supporting frame, the locking assembly is sleeved from top to bottom outside the current transformer body, and the supporting frame is used for supporting the locking assembly.

[0018] Preferably, the both ends of the bottom of the locking assembly are connected with a plurality of clamping rods, the both ends of the inner part of the supporting frame are provided with a plurality of positioning holes, and the clamping rods are correspondingly inserted into the inner part of the positioning holes.

[0019] Compared with the prior art, the utility model has the advantages of the following beneficial effects:

[0020] The three-in-one current transformer provided by the application is matched with the locking assembly in the assembly part and the mounting frame, the position of the assembly part can be flexibly adjusted according to the actual installation space and requirements by the design of the fixed shaft and the locking sleeve, when the position is adjusted to the appropriate position, the assembly part can be firmly fixed by tightening the locking sleeve, the operation is simple and convenient, the flexibility and convenience in the installation process are improved, the installation difficulty caused by the installation position limitation is greatly reduced, and the installation time and labor cost are saved.

[0021] The stability of the locking assembly is enhanced: a rubber rod sleeve is sleeved outside the fixed shaft rod. When the movable plate of the assembly is sleeved on the fixed shaft rod, friction is generated between the rod sleeve and the movable plate, thereby providing additional stability for the assembly during installation, preventing the assembly from shaking or shifting when not completely fixed, and ensuring the stability of the assembly during installation.

[0022] The support frame cooperates with the locking assembly. The clamping rod at the bottom of the locking assembly is inserted into the positioning hole of the support frame, further positioning and supporting the overall structure, preventing the components from deviating due to external forces or vibrations during use, enhancing the stability of the overall structure, and ensuring the reliability of the current transformer during operation.

[0023] The mounting rack is easy to disassemble: the second convex piece and the first convex layer of rubber material at the bottom of the assembly play an important protective and buffering role. The second convex piece increases the friction when the assembly contacts the mounting surface, making the connection between the assembly and the mounting surface more stable and preventing the assembly from sliding. At the same time, the elastic properties of rubber can provide some shock absorption effect, reducing the impact of external vibrations on the overall structure. The first convex layer of rubber material on one side of the assembly contacting the mounting rack can provide some buffering when subjected to external forces, protecting the assembly and the mounting rack from damage caused by external impact, prolonging the service life of the equipment.

[0024] The mounting rack is easy to disassemble: the design of the second preset hole at both ends of the mounting rack and the fastening bolt makes the assembly and disassembly operation between the mounting rack and the current transformer body simple and easy. This not only facilitates the operation during initial installation, but also allows easy disassembly when the three-in-one current transformer needs to be applied to other devices or the mounting rack needs to be maintained, improving the versatility and maintainability of the equipment and reducing the overall maintenance cost.

[0040] An assembly part 2 is symmetrically arranged at both ends of the current transformer body 1, and a movable plate 201 is connected to the assembly part 2.

[0041] A mounting frame 3 is arranged on the outer periphery of the current transformer body 1, and an inner mounting groove 301 is formed on both sides of the mounting frame 3. The movable plate 201 is connected to the corresponding position inside the inner mounting groove 301 through a locking assembly 4.

[0042] Overall structure

[0043] The three-in-one current transformer mainly comprises a current transformer body 1, an assembly part 2, a mounting frame 3, a locking assembly 4, and a support frame 5. The current transformer body 1 is a device for voltage and current conversion in a power system, and has corresponding electrical connection terminals and other structures. The assembly part 2, the mounting frame 3, the locking assembly 4, and the support frame 5 cooperate to achieve flexible installation and adjustment, and provide installation adaptability and structural stability for the current transformer body 1.

[0044] II. Detailed structure and connection method of each component

[0045] Assembly part 2 and mounting frame 3:

[0046] The assembly part 2 is a component with certain functions, and the movable plate 201 is connected thereto. The contact surface at the bottom is provided with a second protruding piece 203 made of rubber material, and a positioning groove 204 is formed on the outer periphery of the bottom. A first protruding layer 202 made of rubber material is glued to one side of the mounting frame 3, and a first preset hole 220 is formed at four corners.

[0047] The mounting frame 3 is a structure arranged on the outer periphery of the current transformer body 1, and an inner mounting groove 301 is formed on both sides thereof. The shape is adapted to part of the current transformer body 1, and a plurality of second preset holes 302 are formed at both ends for locking with the current transformer body 1 through fastening bolts 303, thereby providing a basic structure for the installation of the assembly part 2.

[0048] Locking assembly 4:

[0049] The locking assembly 4 includes a fixed shaft 401 and a locking sleeve 402. The fixed shaft 401 is connected to the horizontal and vertical sides of the inner wall of the mounting groove 301 in the mounting bracket 3, and is covered with a rubber sleeve 403. The fixed shaft 401 has a thread at one end that passes through the assembly 2, and is rotatably connected to the locking sleeve 402 through the thread.

[0050] When the movable plate 201 of the assembly 2 is fitted onto the fixed shaft 401 along the opening of the inner mounting groove 301, the sleeve 403 will generate friction between the movable plate 201 and the fixed shaft 401 to increase the stability during the installation process.

[0051] Support frame 5:

[0052] The support frame 5 is installed at the lower end of the outer periphery of the current transformer body 1, and several positioning holes 501 are opened at both ends inside it.

[0053] Several locking rods 502 are connected to both ends of the bottom of the locking component 4. After the locking component 4 is installed, the locking rods 502 will be inserted into the positioning holes 501 of the support frame 5 to further position the connection between the two and prevent displacement.

[0054] Working principle

[0055] When installing the three-in-one current transformer, firstly, the mounting bracket 3 is installed on the outer periphery of the current transformer body 1 through the second preset holes 302 at both ends and the fastening bolts 303, laying the foundation for the installation of subsequent components. Next, the fixed shaft 401 of the locking assembly 4 is connected to the horizontal and vertical sides of the inner wall of the mounting groove 301 inside the mounting bracket 3. The movable plate 201 of the accessory 2 is fitted onto the fixed shaft 401, and the locking sleeve 402 is threaded onto the fixed shaft 401, but not tightened yet, allowing the accessory 2 to move within a certain range to meet different installation space requirements. During this process, the sleeve 403 provides friction to ensure stable installation. According to the actual installation space and requirements, the position and orientation of the accessory 2 on the mounting bracket 3 are adjusted. After adjustment, the locking sleeve 402 is tightened to secure the movable plate 201 to the corresponding position in the mounting groove 301 inside the mounting bracket 3. If it is necessary to fix the accessory 2 in the corresponding installation position, the first preset hole 220 can be used.

[0056] Meanwhile, before the mounting bracket 3 is fully installed, the support frame 5 is fitted over the current transformer body 1 from top to bottom, located at its lower outer perimeter. After the locking assembly 4 is installed, the locking rod 502 at the bottom of the locking assembly 4 will be inserted into the positioning hole 501 of the support frame 5, enhancing the stability of the overall structure.

[0057] In the working of the three-in-one current transformer, the current transformer main body 1 carries out voltage and current conversion and parameter measurement monitoring, and provides key data for the power system. The assembly 2 is adjusted in position by cooperating with the locking assembly 4 through the movable plate 201, the rod sleeve 403 of rubber material is added during the installation process to increase the adjustment stability, and after installation, the second protruding piece 203 of rubber material increases the friction force when contacting the installation surface, thereby improving the stability; the first protruding layer 202 can be buffered when subjected to external force, thereby protecting the equipment; the positioning groove 204 facilitates the assembly and replacement of the second protruding piece 203. The second preset hole 302 and the fastening bolt 303 of the mounting bracket 3 facilitate assembly and disassembly, and are suitable for other devices. The cooperation of the support frame 5 and the locking assembly 4 prevents the components from being deviated due to external force, thereby ensuring the stable and reliable operation of the equipment.

[0058] Through the above design, the three-in-one current transformer solves the problem of poor applicability of the assembly plate and the integrated structure of the transformer in different installation environments in the prior art, improves the installation flexibility and convenience, reduces the installation difficulty and cost, and ensures the stability and reliability of the equipment in the working.

[0059] It should be understood by those skilled in the art that the embodiments of the utility model shown in the above description and the drawings are only taken as examples and do not limit the utility model. The purpose of the utility model has been completely and effectively realized. The function and structural principle of the utility model have been shown and explained in the embodiments, and the embodiments of the utility model can be any deformation or modification without departing from the principle.
