Description

Technical Field

[0001] This utility model belongs to the field of current transformers, specifically a combined current transformer. Background Technology

[0002] With the improvement of living standards and the vigorous development of the power industry, the application of instrument transformers in daily life is becoming more and more widespread. In power applications, the use of current transformers and voltage transformers is more common. In some existing current transformers and voltage transformers, some circuits are more complex and the use of the transformers is more important. Some wiring points require multiple sets of transformers to be used in combination. A single current transformer or voltage transformer is not effective enough to solve the problems in the existing circuits. Therefore, a combined transformer is needed to solve these problems.

[0003] A combined instrument transformer is an instrument transformer that combines a voltage transformer and a current transformer into one unit. It can simultaneously convert high voltage to low voltage and large current to small current for user convenience. The combined instrument transformer is also known as an open-type current transformer and is suitable for current measurement and microprocessor protection of power supply equipment below 35KV and 10KV in AC power systems.

[0004] Combined instrument transformers are mainly used for current measurement and microprocessor protection of power supply equipment. They are widely used in various power systems. Due to the different installation locations and mounting hole positions, existing combined instrument transformers usually require the use of connectors for installation if the mounting hole positions do not match the mounting positions on the bottom of the transformer in order to ensure the stability of operation.

[0005] In summary, this utility model provides a combined current transformer to solve the above problems. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a combined current transformer to solve the issues in the prior art where the mounting hole positions are inconsistent. In order to ensure the stability of operation, existing combined current transformers usually require the use of connectors for installation if the mounting hole positions do not match the mounting positions at the bottom of the current transformer.

[0007] A combined current transformer includes a current transformer body. Multiple mounting feet are symmetrically arranged at the bottom of the current transformer body. Each mounting foot has a height adjustment component at its bottom, comprising a base block and a lifting sleeve. The base block is fixedly connected to the bottom of the mounting feet. The lifting sleeve is movably fitted onto the surface of the base block. One end of the lifting sleeve is fixedly connected to an adjusting seat. A mounting plate is rotatably connected to the adjusting seat at its end away from the lifting sleeve. The mounting plate has mounting holes and slots. A worm gear cavity is formed within the adjusting seat, and a rotating worm gear is disposed within the worm gear cavity. A self-locking worm is disposed on one side of the rotating worm gear. A lifting screw is vertically connected to the surface of the rotating worm gear. One end of the lifting screw passes through both the adjusting seat and the lifting sleeve and is inserted into the base block.

[0008] Furthermore, one end of the mounting leg is fixedly connected to the bottom of the transformer body, and the other end of the mounting leg is fixedly connected to the height adjustment component.

[0009] Furthermore, the lifting sleeve is a hollow structure with openings at both ends, and one end of the lifting sleeve is sleeved on the outer surface of the base block.

[0010] Furthermore, the end of the rotating worm gear away from the lifting screw is rotatably connected to the bottom of the worm gear cavity, and the bottom of the base block is inserted into one end of the lifting screw and is connected to the base block by a thread.

[0011] Furthermore, one end of the self-locking worm is rotatably connected to the inner wall of the worm wheel cavity, and the other end movably passes through the adjusting seat and is fixedly connected to an anti-slip rotating block. The self-locking worm meshes with the rotating worm wheel.

[0012] Furthermore, the top of the adjusting seat is provided with a through hole, which connects the worm gear cavity and the interior of the lifting sleeve respectively, and one end of the lifting screw is movably inserted through the through hole.

[0013] Furthermore, the adjusting seat is rotatably connected to one end of the mounting plate, and the mounting hole slot is opened along the length direction of the mounting plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, by setting a height adjustment component at the bottom of the mounting feet, can individually adjust the height of each mounting foot according to different installation positions, thereby maintaining the horizontal level of the current transformer body during installation. By setting a mounting rotating plate, during installation, rotating the mounting rotating plate causes the mounting hole slot to rotate and match the mounting hole, allowing installation to be carried out without the aid of connecting parts, making it more stable.

[0016] 2. This utility model sets up a self-locking worm gear and a rotating worm wheel for meshing. When both are being adjusted, the self-locking worm gear enables transmission. When not being adjusted, the self-locking worm gear can achieve the self-locking function between the two without affecting the overall height. Attached Figure Description

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] like Figures 1-4 As shown, this utility model provides a combined current transformer, including a current transformer body 1. Multiple mounting feet 2 are installed at the bottom of the current transformer body 1, arranged symmetrically. Each mounting foot 2 has a height adjustment component at its bottom, comprising a base block 6 and a lifting sleeve 3. The base block 6 is fixedly connected to the bottom of the mounting feet 2. The lifting sleeve 3 is movably fitted onto the surface of the base block 6. One end of the lifting sleeve 3 is fixedly connected to an adjusting seat 4. A mounting rotating plate 5 is rotatably connected to the end of the adjusting seat 4 away from the lifting sleeve 3. The mounting rotating plate 5 has a mounting hole groove 7. A worm gear cavity 11 is formed inside the adjusting seat 4. A rotating worm gear 10 is arranged inside the worm gear cavity 11. A self-locking worm 8 is arranged on one side of the rotating worm gear 10. A lifting screw 9 is vertically connected to the surface of the rotating worm gear 10. One end of the lifting screw 9 passes through the adjusting seat 4 and the lifting sleeve 3, and is inserted into the base block 6.

[0025] In one embodiment of this utility model, one end of the mounting leg 2 is fixedly connected to the bottom of the transformer body 1, and the other end of the mounting leg 2 is fixedly connected to the height adjustment component.

[0026] As one embodiment of this utility model, the lifting sleeve 3 is a hollow structure with openings at both ends, and one end of the lifting sleeve 3 is sleeved on the outer surface of the base block 6.

[0027] In one embodiment of this utility model, the end of the rotating worm gear 10 away from the lifting screw 9 is rotatably connected to the bottom of the worm gear cavity 11. The bottom of the lifting screw 9 is inserted into the base block 6 at one end and is connected to the base block 6 by a thread.

[0028] In one embodiment of this utility model, one end of the self-locking worm 8 is rotatably connected to the inner wall of the worm wheel cavity 11, and the other end movably passes through the adjusting seat 4 and is fixedly connected to the anti-slip rotating block 12. The self-locking worm 8 and the rotating worm wheel 10 are meshed.

[0029] As one embodiment of this utility model, the top of the adjusting seat 4 is provided with a through hole, which connects the worm gear cavity 11 and the interior of the lifting sleeve 3 respectively, and one end of the lifting screw 9 is movably passed through the through hole.

[0030] In one embodiment of this utility model, the adjusting seat 4 is rotatably connected to one end of the mounting plate 5, and the mounting hole groove 7 is opened along the length direction of the mounting plate 5.

[0031] Specific working principle:

[0032] By setting a height adjustment component at the bottom of the mounting leg 2, the height of each mounting leg 2 can be adjusted individually according to different installation positions, thereby maintaining the horizontal level of the transformer body 1 during installation. By setting a mounting rotating plate 5, during installation, rotating the mounting rotating plate causes the mounting hole slot 7 to rotate and match the mounting hole, allowing for installation without the aid of connecting parts, making it more stable. By setting a self-locking worm gear 8 to mesh with the rotating worm wheel 10, the self-locking worm gear 8 provides transmission when both are adjusted, and when not adjusted, the self-locking worm gear 8 can achieve a self-locking function between the two without affecting the overall height.

[0033] The lifting sleeve 3 is movably fitted onto the surface of the base block 6, so that it can slide freely up and down on the surface of the lifting sleeve 3 to adjust the distance between the bottom of the lifting sleeve 3 and the top of the base block 6.

[0034] The mounting plate 5 is designed so that during installation, the corresponding points of the mounting holes 7 on the mounting plate 5 can be adjusted according to the installation position.

[0035] By rotating the anti-slip block 12, the bottom of the current transformer body 1 can be kept horizontal during installation;

[0036] When the anti-slip rotating block 12 is rotated, the self-locking worm gear 8 is driven to rotate, and the lifting screw 9 is driven to rotate by the rotating worm wheel 10, so that it can rotate inside the base block 6. The base block 6 is restricted by the mounting feet 2. Therefore, the lifting screw 9 pushes the base block 6 to rise or fall, thereby achieving the purpose of height adjustment.

[0037] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
