Description

Technical Field

[0001] The invention relates to the field of combined mutual inductors, in particular to a combined mutual inductor that is easy to install. Background Art

[0002] The principle of current transformer is based on the principle of electromagnetic induction. The current transformer is composed of a closed iron core and windings. Its primary winding has few turns and is connected in series in the circuit of the current to be measured, so it often has the entire current of the circuit flowing through it. The secondary winding has more turns and is connected in series in the measuring instrument and the protection circuit. When the current transformer is working, its secondary circuit is always closed, so the impedance of the series coil of the measuring instrument and the protection circuit is very small, and the working state of the current transformer is close to short circuit.

[0003] Existing combined mutual inductors generally require the wires to be passed through the detection hole before they can be detected through the closed iron core and winding inside the mutual inductor. However, under normal circumstances, the wires are not at the very center of the iron core, and the current does not pass through the iron core completely vertically, resulting in different magnetic field strengths generated in different parts of the iron core. The local magnetic field strength is too strong, causing the local temperature of the iron core to be too high, which will affect the detection data. Moreover, when the wire layout is completed and a combined mutual inductor needs to be added, the wires need to be removed. After the combined mutual inductor is installed, the wires need to be passed through the combined mutual inductor to complete the addition of the combined mutual inductor, which is very complicated and inconvenient.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0040] See also Figure 1-4 A combined transformer that is easy to install includes a housing 1 and three detection holes arranged at one end of the housing 1. An adjusting device 2 is arranged at the lower end of the housing 1. The adjusting device 2 can be operated to push the wire to the detection hole. A clamping device 3 is also arranged inside the detection hole. The clamping device 3 is used to clamp and fix the wire;

[0041] The adjusting device 2 comprises an adjusting slot arranged at the lower end of the housing 1, a disc 24 is rotatably connected inside the adjusting slot, a sliding post 22 is slidably connected to one end of the disc 24, an adjusting block 21 is installed at the lower end of the sliding post 22, and the adjusting block 21 is operable to swing.

[0042] An adjusting device 2 and a clamping device 3 are installed inside the housing 1, the housing 1 is placed on the upper end of the wire, the position of the wire is adjusted by swinging the adjusting device 2, the wire is pushed to the detection hole by the adjusting device 2, and then the wire is clamped by the clamping device 3 so that the wire is at the axis of the detection hole, so that the combined mutual inductor can be easily installed;

[0043] Specifically, according to Figure 4As shown, after the layout of the wires in the electrical cabinet is completed and a combined mutual inductor needs to be added, the housing 1 is pressed on the wires, and the disc 24 is driven to slide, and the disc 24 is used to drive the adjusting block 21 to slide, and every two wires are separated by the adjusting block 21, and the sliding adjusting block 21 is used to separate the messy wires, so that several wires are close to the detection hole, and then the disc 24 is rotated, and the disc 24 is used to drive the adjusting block 21 to rotate and swing, and the adjusting block 21 swings to squeeze the wires to the detection hole, and then the housing 1 is continuously lowered, so that the wires will be close to the axis of the detection hole, and the wires are clamped by two clamping devices 3. Since the two clamping devices 3 slide toward the axis at the same time, the clamping devices 3 squeeze and fix the wires at the axis of the detection hole, so that the housing 1 can be installed as needed, and the messy wires can be automatically separated into their respective detection holes, and the wires are fixed at the axis of the detection hole through the two clamping devices 3. Example

[0044] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-4 The housing 1 is also slidably connected to a slide 25, the slide post 22 is used to squeeze the slide 25 to slide, the two ends of the slide 25 are rotatably connected to a rotating disk 26, the rotating disk 26 and the slide 25 are connected by a sixth spring 29, and a spring 28 is also installed at the lower end of the slide 25, the rotating disk 26 can be operably abutted against the spring 28, and one end of the spring 28 is fixedly connected to the slide 25;

[0045] A second spring 23 is installed on the outer surface of the sliding column 22 . One end of the second spring 23 is connected to the upper end of the adjustment block 21 , and the other end of the second spring 23 is connected to the lower end of the disc 24 .

[0046] In order to prevent the clamping device 3 from failing to detect the passing wire, a slide 25 and a rotating disk 26 are slidably connected at the lower end of the housing 1. When the adjusting block 21 squeezes the wire to the detection hole, the wire squeezes the rotating disk 26 to swing upward, so that the wire passes through the rotating disk 26, and then the adjusting block 21 abuts against the inner shell of the electrical cabinet. By continuously pressing the housing 1 downward, the wire abuts against the upper end of the rotating disk 26, and the adjusting block 21 is squeezed and slides upward through the inner shell of the electrical cabinet, so that the adjusting block 21 pushes the slide column 22 to slide upward, and the slide column 22 squeezes the slide column 25 to slide upward, and the rotating disk 26 and the wire are driven to slide upward through the slide column 25, so as to approach the clamping device 3;

[0047] It should be particularly noted that when the wire is too thick, since the distance that the slide 25 slides upward is fixed, when the rotating disk 26 drives the thick wire to slide upward, the thick wire will abut against the inner wall of the housing 1, causing the slide 25 to be unable to continue to slide upward. Therefore, a spring sheet 28 is installed at the lower end of the slide 25, and the other end of the spring sheet 28 can be operably abutted against the rotating disk 26. When the slide 25 drives the rotating disk 26 and the thick wire to continue to slide upward, one end of the spring sheet 28 is squeezed by the rotating disk 26 to deform, thereby achieving that wires of different sizes can be close to the clamping device 3, which is convenient for the clamping device 3 to clamp;

[0048] A first cavity 9 is provided inside the clamping device 3 , and a first piston rod 10 is slidably connected to one side of the first cavity 9 . The first piston rod 10 is connected to the clamping device 3 , and the clamping device 3 is connected to the housing 1 via a first spring 11 .

[0049] By filling the first cavity 9 with liquid, the liquid will squeeze the first piston rod 10 to slide to one side, and the first piston rod 10 will drive the clamping device 3 to clamp on the wire. Example

[0050] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-5 A sliding device 4 is installed on one side of the housing 1, and the sliding device 4 is used to drive the adjusting device 2 to swing;

[0051] The sliding device 4 includes a protective shell 41 installed on one side of the housing 1, a third chamber 42 is provided inside the protective shell 41, a piston disc 43 is slidably connected inside the third chamber 42, a shaft column 45 is installed on one side of the piston disc 43, the shaft column 45 is connected to the disc 24, and a fifth spring 46 is also installed on the outer surface of the shaft column 45, and the fifth spring 46 is connected to the housing 1;

[0052] An inclined block 49 is also installed on the outer surface of the shaft column 45, and a protruding block 48 is installed on the inner wall of the protective shell 41. The protruding block 48 can be operated to squeeze the inclined block 49 to swing.

[0053] By filling one end of the piston disc 43 with liquid, the piston disc 43 and the shaft column 45 are pushed to slide toward one end by the liquid, so that the shaft column 45 drives the disc 24 and the adjusting block 21 to slide, so that the adjusting block 21 can separate the messy wires. Figure 6 As shown, when the shaft column 45 slides to the left, the shaft column 45 will drive the inclined block 49 to contact the protruding block 48, and the protruding block 48 will squeeze the inclined block 49 to rotate and swing a certain angle, and the inclined block 49 will drive the shaft column 45 to rotate and swing. When the protruding block 48 no longer contacts the inclined block 49, the elastic force of the fifth spring 46 drives the shaft column 45 to reset, and the cycle repeats, using a plurality of inclined blocks 49 to cooperate with the protruding block 48 to achieve the shaft column 45 driving the adjustment block 21 to continuously swing. Example

[0054] This embodiment is an improvement made on the basis of embodiment 3. For details, please refer to Figure 1-5 , at least two sliding devices 4 are provided on one side of the housing 1, and a third tube 47 is connected between every two sliding devices 4;

[0055] The lower end of the third tube 47 is communicated with the interior of the third chamber 42 .

[0056] Reduce the fault tolerance rate: when several adjustment blocks 21 slide together, several adjustment blocks 21 squeeze on the wires together, which will cause several wires to squeeze each other, and the adjustment block 21 cannot squeeze the messy wires to move. Therefore, in order to achieve that the adjustment block 21 can separate the messy wires to the detection hole, every two protective shells 41 are connected by a third tube 47, and the first tube 7 is connected to the first protective shell 41. The liquid is transported to the inside of the first third cavity 42 through the first tube 7, so that the adjustment block 21 of the first adjustment device 2 will slide and squeeze the wires. Then, when the piston disc 43 moves to the third tube 47, the liquid on one side of the piston disc 43 will flow through the third tube 47 to the inside of the third cavity 42 of the second sliding device 4, thereby driving the second adjustment block 21 to slide and squeeze the wires, and so on and so forth, thereby achieving continuous squeezing of the messy wires;

[0057] It should be noted that when the piston disc 43 of the first sliding device 4 approaches the third tube 47 , the hydraulic pressure inside the third chamber 42 of the first sliding device 4 will not change much, so the third chamber 42 of the first sliding device 4 will not be pulled back to its original position by the third chamber 42 . Example

[0058] This embodiment is an improvement made on the basis of embodiment 4. For details, please refer to Figure 1-6 A driving device 5 is also installed inside the housing 1. The driving device 5 includes a prismatic column 51 rotatably connected to the inside of the housing 1. The lower end of the prismatic column 51 is rotatably connected to an internal thread sleeve 52. The lower end of the internal thread sleeve 52 is threadedly connected to a threaded column 53. Support frames 55 are also installed at both ends of the housing 1. The upper end of the support frame 55 is sleeved with an internal thread frame 56. The two internal thread frames 56 are connected by a synchronous belt 54.

[0059] The two ends of the housing 1 are also rotatably connected with threaded rods 57, the threaded rods 57 are rotatably connected to the inside of the support frame 55 and the internal threaded frame 56, and the threaded rods 57 pass through the lower end of the housing 1;

[0060] The housing 1 is provided with a piston cavity 59, the lower end of the threaded column 53 is rotatably connected to a square plate 58, and the square plate 58 is slidably connected to the inside of the piston cavity 59;

[0061] The piston chamber 59 includes a first square groove, a second square groove and a third square groove, which are arranged in sequence, and the first square groove and the third square groove have the same size, and the second square groove is larger than the first square groove and the third square groove;

[0062] A first one-way valve 6 is also installed inside the housing 1, and the first one-way valve 6 is connected to the piston chamber 59. A second tube 8 is installed at the lower end of the first one-way valve 6, and the second tube 8 is connected to the first chamber 9.

[0063] A fourth spring 44 is installed inside the protective shell 41, and the fourth spring 44 is connected to the piston disc 43;

[0064] The elastic force of the fourth spring 44 of each sliding device 4 gradually increases.

[0065] A first tube 7 is also installed inside the housing 1 . One end of the first tube 7 is connected to the piston chamber 59 , and the other end of the first tube 7 is connected to the third chamber 42 .

[0066] By rotating the prismatic column 51, the prismatic column 51 drives the internal thread sleeve 52 to rotate, the internal thread sleeve 52 drives the synchronous belt 54 to rotate, and the synchronous belt 54 drives the internal thread frame 56 and the threaded rod 57 to rotate, so that the threaded rod 57 will rotate into the threaded hole on the electrical cabinet, thereby achieving fixation, and under the action of the threaded rod 57, the housing 1 will continue to fit the inner wall of the electrical cabinet;

[0067] When the internal thread sleeve 52 rotates, the internal thread sleeve 52 drives the threaded column 53 to rotate. Since the lower end of the threaded column 53 is rotatably connected to the square plate 58, all the threaded columns 53 drive the square plate 58 to slide downward, and the liquid inside the piston chamber 59 is squeezed to the first tube 7 through the square plate 58, and the liquid is squeezed to the third chamber 42 of the first sliding device 4 through the first tube 7, so that a plurality of adjustment blocks 21 can squeeze the wires in sequence;

[0068] It should be noted that the liquid in the first square groove is sufficient to push all the piston discs 43 to slide;

[0069] When the square plate 58 moves to the second square groove, since the size of the second square groove is larger than the square plate 58, the liquid inside the third chamber 42 loses pressure, and the piston plate 43 is pushed back to its original position by the fourth spring 44, so that the adjustment block 21 can slide the messy wires close to the detection hole again;

[0070] It should be particularly noted that the elastic force of the fourth spring 44 of each sliding device 4 gradually increases. Therefore, when the third chamber 42 of each sliding device 4 is depressurized, the fourth spring 44 with the largest elastic force first pulls the piston disc 43 to reset. Moreover, when the fourth spring 44 with the largest elastic force pulls the piston disc 43 to reset, the piston disc 43 will also squeeze the liquid into the third chamber 42 of another sliding device 4, thereby ensuring that the pressure of the piston discs 43 of the remaining sliding devices 4 is stable and will not be pulled and moved by the fourth spring 44. Therefore, when the fourth spring 44 with the largest elastic force pulls the piston disc 43 to reset, the second fourth spring 44 will pull the piston disc 43 to reset, and the cycle will repeat. In this way, a number of adjustment blocks 21 can squeeze the messy wires in turn again. Example

[0071] This embodiment is an improvement made on the basis of embodiment 5. For details, please refer to Figure 1-7 A cylindrical groove 13 is provided at one end of the first piston rod 10, and a second one-way valve 12 is installed inside the cylindrical groove 13;

[0072] The clamping device 3 includes an arc plate 31 installed on one side of the first piston rod 10, a second cavity 33 is provided inside the arc plate 31, a slide plate 34 is slidably connected inside the second cavity 33, a through groove 32 is also provided inside the arc plate 31, the through groove 32 is connected to the second cavity 33, and the through groove 32 is also connected to the cylindrical groove 13;

[0073] A connecting groove 37 is further provided inside the arc plate 31, an air bag 38 is installed on one side of the slide plate 34, and a conveying groove 35 is further provided on one side of the slide plate 34, and the conveying groove 35 is connected to the inside of the air bag 38;

[0074] A third spring 36 is further installed inside the arc plate 31 , and the third spring 36 is connected to the slide plate 34 .

[0075] As shown in Figure 5, when the square plate 58 squeezes the liquid inside the piston chamber 59, the first one-way valve 6 will not be squeezed open, and the pressure relief value of the first one-way valve 6 is greater than the hydraulic pressure in the first square groove. When the square plate 58 slides to the third groove, the hydraulic pressure value of the third groove is greater than the pressure relief value of the first one-way valve 6, so the first one-way valve 6 will be squeezed open, so that the liquid in the third groove will pass through the first one-way valve 6 into the second tube 8 and the first chamber 9, so that the clamping device 3 can clamp the wire;

[0076] according to Figure 7As shown, the pressure relief value of the second one-way valve 12 is greater than the hydraulic pressure inside the first chamber 9. When the liquid continues to be filled into the first chamber 9, the second one-way valve 12 will be squeezed open, so that the liquid will enter the cylindrical groove 13 and the through groove 32, so that the slide plate 34 is squeezed by the liquid to slide, so that the slide plate 34 slides out of the arc plate 31, thereby increasing the clamping area of ​​the arc plate 31, so that the arc plate 31 can better fix the wire;

[0077] When the slide plate 34 slides to the inner limit position of the arc plate 31, according to Figure 7 As shown, the connecting groove 37 is connected to the second cavity 33, and the connecting groove 37 is connected to the conveying groove 35, so that the liquid in the second cavity 33 enters the conveying groove 35 through the connecting groove 37, and the liquid is conveyed to the airbag 38 through the conveying groove 35, so that the airbag 38 expands and contacts the wire, so that the airbag 38 and the arc plate 31 can better fix wires of different sizes.
