The current transformer usually includes a winding coil, a closed iron core and a detection wire. The middle part of the closed iron core has a through hole, the winding coil is wound on the closed iron core, and the detection wire is passed through the through hole in the middle of the closed iron core. When current passes through the detection wire, an induced alternating magnetic field will be generated in the closed iron core due to electromagnetic induction. Similarly, due to electromagnetic induction, an induced current will be generated in the winding coil. By detecting the current in the winding coil, the current in the detection wire can be obtained through the corresponding formula calculation or proportional relationship.

In addition, in many usage scenarios, the current transformer needs to be fixed to avoid the current transformer shaking and causing inaccurate detection results. Therefore, the shell of the current transformer is usually provided with a protrusion for fixing. When in use, the protrusion is used to fix the shell and the current transformer to the external structure to ensure the stability of the current transformer when in use.

[0035] See also Figure 1 , Figure 1 The front structural diagram of a current transformer installation device in an embodiment of the present application is shown, which is a current transformer installation device, comprising a shell body 100, a storage assembly 200, a movable mechanism 300 and a fixing assembly 400. The storage assembly 200 is arranged on one side of the shell body 100 and connected to the side wall of the shell body 100. The movable mechanism 300 is connected to the storage assembly 200 and is stored inside the storage assembly 200; the movable mechanism 300 can extend out of the storage assembly 200. The fixing assembly 400 is arranged on the movable mechanism 300, and the movable mechanism 300 is fixed to the external structure through the fixing assembly 400.

[0036] like Figure 1 and Figure 2As shown, it should be noted that the current transformer is arranged inside the shell body 100 to protect the current transformer from being damaged due to external impact. The storage assembly 200 is fixedly connected to the shell body 100, and the shell body 100 and the current transformer can be fixed by fixing the storage assembly 200. The fixed assembly 400 is arranged on the movable mechanism 300, and can be connected to the external structure by bonding, hinged, clamping, etc. The external structure can be a wall, a ground or other stable structure to fix the movable mechanism 300, thereby fixing the storage assembly 200; the movable mechanism 300 and the storage assembly 200 can be slidably connected or rotatably connected, so that the movable mechanism 300 can move between the inside and outside of the storage assembly 200, and the fixed assembly 400 moves with the movable mechanism 300.

[0037] When the current transformer needs to be used, the movable mechanism 300 is moved to the outside of the storage assembly 200, and the movable mechanism 300 is fixed to the external structure by the fixing assembly 400. At this time, the movable mechanism 300 cannot move, so that the shell body 100 and the current transformer are fixed, and the installation is completed. After use, the fixing between the fixing assembly 400 and the external structure is released, and the movable mechanism 300 can move. The movable mechanism 300 is stored in the storage assembly 200, which can reduce the volume of the device and facilitate storage or transportation.

[0038] Through the above arrangement, when the current transformer needs to be used, the movable mechanism 300 can be moved to the outside of the storage component 200, and the shell body 100 can be fixed by the fixing component 400, so that the current transformer is not easy to deviate and shake during use, and the detection accuracy is effectively improved. After the current transformer is used, the fixing between the contact fixing component 400 and the external structure is fixed, and the movable mechanism 300 is stored inside the storage component 200, which can effectively reduce the size of the device, facilitate storage and transportation, and the disassembly and assembly operation of the device is simple and convenient, and easy to use.

[0039] In some of the embodiments, the fixing assembly 400 includes a fixing bolt 410 and a clamping assembly 420. The movable mechanism 300 is provided with a threaded hole 310 matching the fixing bolt 410. The fixing bolt 410 is inserted into the threaded hole 310 and is threadedly connected to the inner wall of the threaded hole 310. The movable mechanism 300 is fixed to the external structure through the fixing bolt 410; the clamping assembly 420 abuts against both sides of the fixing bolt 410.

[0040] like Figure 3 and Figure 4As shown, it should be noted that when fixing the movable mechanism 300, the fixing bolt 410 is inserted into the threaded hole 310 and the external structure at the same time, so that the movable mechanism 300 is fixed on the external structure. After the fixing is completed, the clamping assembly 420 abuts against both sides of the nut of the fixing bolt 410 to prevent the fixing bolt 410 from rotating and loosening, thereby improving the installation stability.

[0041] In some of the embodiments, the clamping assembly 420 includes a clamping member 421, a fixing member 422 and a spring 423, the fixing member 422 is connected to the movable mechanism 300, one end of the spring 423 is connected to the fixing member 422, and the other end of the spring 423 is connected to the clamping member 421, and the clamping member 421 abuts against both sides of the fixing bolt 410.

[0042] like Figure 3 and Figure 4 As shown, preferably, the clamping assembly 420 further includes a pull rod 424, a fixing member 422 is disposed at the end of the movable mechanism 300 away from the storage assembly 200, and the threaded hole 310 is opened at the end position of the movable mechanism 300 close to the fixing member 422. The pull rod 424 is slidably connected to the fixing member 422, the pull rod 424 points to the threaded hole 310, the spring 423 is sleeved on the outer periphery of the pull rod 424, the clamping member 421 is connected to one end of the pull rod 424 close to the threaded hole 310, and the spring 423 provides elastic force to ensure that the clamping member 421 is at the position where the threaded hole 310 is located when the spring 423 is not subjected to external force. Pulling the pull rod 424 can compress the spring 423, so that the clamping member 421 is away from the threaded hole 310. When the pull rod 424 is not subjected to external force, the spring 423 rebounds, and the clamping member 421 returns to the position where the threaded hole 310 is located. The clamping member 421 is a U-shaped member, and two opposite inner side walls of the U-shaped member are respectively in contact with two sides of the nut of the fixing bolt 410 to prevent the fixing bolt 410 from loosening.

[0043] When installing the fixing assembly 400, pull the pull rod 424 to move the clamping member 421 away from the position of the threaded hole 310 to provide space for the installation of the fixing bolt 410, then insert the fixing bolt 410 into the threaded hole 310 to fix the movable mechanism 300, rotate the side opposite to the nut of the fixing bolt 410 to be parallel to the inner side wall opposite to the clamping member 421, loosen the pull rod 424, and the clamping member 421 moves in the direction of the threaded hole 310 under the elastic force of the spring 423, and the clamping member 421 finally abuts on both sides of the nut of the fixing bolt 410. The fixing bolt 410 is not easy to rotate under the abutment of the clamping member 421, which can effectively prevent the fixing bolt 410 from loosening or falling off, thereby greatly improving the installation stability of the device.

[0044] In some embodiments, the storage assembly 200 includes a base 210, which is disposed on one side of the shell body 100 and connected to the side wall of the shell body 100, and the movable mechanism 300 is connected to the base 210; a storage cavity 220 is disposed inside the base 210, and the movable mechanism 300 is stored in the storage cavity 220.

[0045] like Figure 2 and Figure 5 As shown, preferably, an opening is provided on the surface of the base 210, and the opening is connected to the storage chamber 220. The movable mechanism 300 and the base 210 can be connected by sliding or rotating, so that the movable mechanism 300 can move between the inside and outside of the base 210 through the opening to store the movable mechanism 300, which is convenient for storage and transportation. In addition, the volume of the storage chamber 220 matches the volume of the movable mechanism 300. When the movable mechanism 300 is stored in the storage chamber 220, the movable mechanism 300 fits with the inner wall of the storage chamber 220, so as to fully reduce the volume of the device and improve portability.

[0046] In some embodiments, a sliding groove 221 is formed on the side wall of the storage cavity 220 , and the movable mechanism 300 is engaged in the sliding groove 221 and slides along the length direction of the sliding groove 221 .

[0047] like Figure 5 As shown, preferably, the movable mechanism 300 is slidably connected with the base 210 through a slide groove 221, and two openings are provided, and are respectively provided on opposite sides of the base 210, and the slide groove 221 extends from the opening on one side of the base 210 to the opening on the other side. In contrast, the movable mechanism 300 is provided with two corresponding openings, and the two movable mechanisms 300 slide along the slide groove 221 respectively, and can move between the inside and outside of the storage chamber 220. When installing the device, a force away from the base 210 is applied to the movable mechanism 300, and the movable mechanism 300 can move along the slide groove 221, so that the fixing assembly 400 is exposed to the outside of the base 210, which is convenient for installation and fixing. When the movable mechanism 300 needs to be stored in the storage assembly 200, the movable mechanism 300 can be pushed toward the base 210 to complete the storage. Through the above arrangement, the movable mechanism 300 can be quickly stored, and the operation is simple.

[0048] In some of the embodiments, a limiting groove 222 is further provided on the side wall of the storage cavity 220; the movable mechanism 300 includes a fixed plate 320 and a limiting block 330, the fixed plate 320 is engaged with the slide groove 221, the limiting block 330 is connected to the fixed plate 320, the limiting block 330 is engaged in the limiting groove 222, and slides in the limiting groove 222.

[0049] like Figure 2 and Figure 5As shown, preferably, two fixing plates 320 are provided, and both sides of the fixing plates 320 are clamped in the slide grooves 221 on both sides of the receiving cavity 220. The limiting block 330 is fixedly connected to the side of the fixing plate 320 away from the shell body 100, and correspondingly, the limiting groove 222 is opened on the side of the receiving cavity 220 away from the shell body 100, and the limiting block 330 slides in the limiting groove 222 to ensure that the fixing plate 320 cannot completely escape from the slide groove 221 from the opening.

[0050] like Figure 2 As shown, when the limit block 330 moves to the end of the limit slot 222 close to the middle of the base 210, the fixed plate 320 is completely received in the storage cavity 220; when the limit block 330 is located at the end of the limit slot 222 close to the side of the base 210, part of the structure of the fixed plate 320 and the fixing assembly 400 are located outside the storage cavity 220, and the limit block 330 abuts against the end of the limit slot 222, and the fixed plate 320 cannot continue to move away from the base 210, to ensure that the fixed plate 320 cannot completely disengage from the slide slot 221, thereby avoiding the loss of the fixed plate 320.

[0051] In some of the embodiments, the movable mechanism 300 further includes a handle 340 . The handle 340 is disposed at an end of the fixing plate 320 away from the storage assembly 200 .

[0052] like Figure 2 , Figure 3 and Figure 4 As shown, preferably, the handle 340 is fixedly connected to the end of the fixing plate 320 away from the base 210, and the fixing plate 320 can be driven to slide along the slide groove 221 by pushing and pulling the handle 340, which is convenient for users to operate.

[0053] In some of the embodiments, a detection hole 110 is opened on the surface of the shell body 100, and the detection hole 110 is used to pass a detection wire of the current transformer (not shown in the figure). The current transformer installation device also includes a clamping mechanism 500, which is arranged in the detection hole 110 and connected to the shell body 100. The clamping mechanism 500 is used to clamp the detection wire.

[0054] like Figure 1 , Figure 6 and Figure 7 As shown, preferably, the detection hole 110 is arranged corresponding to the through hole of the closed iron core, so that the detection wire is passed through the detection hole 110 and the through hole of the closed iron core at the same time, so as to realize the detection function of the current transformer. The clamping mechanism 500 is arranged at the detection hole 110 and connected to the inner wall of the detection hole 110. The clamping mechanism 500 clamps the detection wire in the detection hole 110, which can prevent the detection wire from shaking or detaching from the detection hole 110 during the detection process, and further improve the detection accuracy of the current transformer.

[0055] In some of the embodiments, the clamping mechanism 500 includes correspondingly arranged telescopic mechanisms 510 and abutment members 520. A plurality of telescopic mechanisms 510 are arranged at intervals along the side walls of the detection hole 110 and are connected to the shell body 100. The telescopic mechanisms 510 move radially along the detection hole 110. The abutment member 520 is connected to the telescopic mechanism 510 and moves with the telescopic mechanism 510. The abutment member 520 abuts against the detection wire.

[0056] like Figure 1 , Figure 6 and Figure 7 As shown, it should be noted that the detection wire is passed through the detection hole 110. Since the diameter of the detection wire needs to be determined according to the magnitude of the current flowing through it, the aperture of the detection hole 110 does not match the diameter of the detection wire. The aperture of the detection hole 110 is larger than the diameter of the detection wire to ensure that detection wires of different diameters can be smoothly passed through the detection hole 110. When the detection wire needs to be clamped, the multiple telescopic mechanisms 510 drive the abutment 520 to move toward the center of the detection hole 110, so that the multiple abutment can abut against the outer surface of the detection wire from different directions, thereby fixing the detection wire and preventing the detection wire from deflecting.

[0057] In some embodiments, the telescopic mechanism 510 includes a rack 511 and a gear 512 , the gear 512 is connected to the shell body 100 , the rack 511 is meshed with the gear 512 , and is arranged along the radial direction of the detection hole 110 ; the abutment 520 is connected to the rack 511 .

[0058] like Figure 1 , Figure 6 and Figure 7 As shown, preferably, the clamping mechanism 500 also includes an annular clamping bracket 530, the clamping bracket 530 is fixedly connected to the inner side wall of the detection hole 110, and a plurality of gears 512 are arranged at equal intervals along the clamping bracket 530 and are rotatably connected to the clamping bracket 530. Adjacent gears 512 are connected by adapters 540. When one gear 512 rotates, it can drive other gears 512 to rotate synchronously to ensure that the rack 511 moves synchronously. When it is necessary to clamp the detection wire, the driving gear 512 rotates, and all the racks 511 are synchronously moved toward the center of the detection hole 110 driven by the corresponding gears 512 until all the abutment members 520 abut against the outside of the detection wire. By setting the gears 512 and the racks 511, the abutment members 520 can be quickly adjusted to clamp and fix the detection wire, and the operation is simple and fast.

[0059] In addition, since the gears 512 are connected by the adapter 540, the driving device only needs to be connected to one gear 512 to realize the control of the telescopic mechanism 510, and the driving device can be a rocker or a motor. Since all the racks 511 move synchronously toward the center of the detection hole 110, when the abutment 520 abuts against the outside of the detection wire, the extension distance of the rack 511 is equal, so that the detection wire is located at the center of the detection hole 110, which can ensure the concentricity of the detection wire with the closed iron core, uniformly detect the magnetic field induced by the wire, and make the detection result of the current transformer more accurate.

[0060] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
