DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] Embodiment 1, as Figure 1 and Figure 2 As shown, a current transformer fault detection device includes a base 1 and a current transformer body 7, support legs 2 are fixedly connected at the four corners of the lower end of the base 1, a control box 3 is fixedly installed at the front end of the base 1, a detection box 4 is arranged at the rear part of the upper end of the base 1, wiring pins 8 are fixedly installed symmetrically on the upper end of the current transformer body 7, a conveying detection component 5 is commonly arranged on the inner surface and the upper end of the base 1, and a cleaning component 6 is commonly arranged at the middle part and the left end of the upper end of the base 1.

[0033] During the implementation of this embodiment, the current transformer body 7 is placed on the conveying detection component 5. At this time, the control box 3 is operated to control the conveying detection component 5 to automatically clamp the current transformer body 7 during the conveying process, and the debris attached to the terminal pin 8 is cleaned by the cleaning component 6 during the conveying process. Then, during the conveying process, the current transformer body 7 is driven to flip 90 degrees, and the terminal pin 8 and the detection box 4 are energized to form a series circuit. The current returns to the detection box 4 through the current transformer body 7, and it is judged whether the conductor is faulty by the feedback current signal.

[0034] The control box 3 mentioned above is a mature control technology means and equipment in the prior art. In this solution, its controllable functions are utilized, and its structure, connection method and principle are not further elaborated.

[0035] The detection box 4 mentioned above is a mature detection technology means and equipment in the prior art. In this scheme, the output current and the current transformer body 7 are used to form a series circuit, and the feedback current signal is used to determine whether the current transformer body 7 is faulty. Its structure, connection method and principle will not be explained again.

[0036] The current transformer body 7 mentioned above is an instrument based on the principle of electromagnetic induction in the prior art, and is a device used to convert a large current on the primary side into a small current on the secondary side for measurement. Its structure and principle will not be elaborated any more.

[0037] Specifically, in order to realize automatic clamping and transportation of the current transformer body 7 and realize fault detection during transportation, refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 In this embodiment, the conveying detection component 5 includes two rotating holes 51 opened at the left end of the base 1, a conveying mechanism 52 is arranged on the inner surface of the base 1, a clamping and rotating mechanism 53 and a positioning mechanism 54 are symmetrically arranged on the upper end of the conveying mechanism 52, and a detection protection mechanism 55 is arranged at the rear of the upper end of the base 1.

[0038] For further information, see Figure 3 , Figure 4 and Figure 5 In this embodiment, the conveying mechanism 52 includes two rotating rods 521 rotatably connected to the inner surface of the rotating hole 51, and the left end of the front rotating rod 521 is fixedly connected to a double-axis motor 526 fixedly connected to the left end of the base 1. The outer surfaces of the two rotating rods 521 are symmetrically fixedly connected to transmission wheels 522, and the outer surfaces of the transmission wheels 522 on the same side are commonly wound with a conveyor belt 523. The upper end of the base 1 is symmetrically provided with slide grooves 525, and the inner surfaces of the two slide grooves 525 are slidably connected to sliders 524 fixedly connected to the conveyor belt 523.

[0039] For further information, see Figure 4 , Figure 6 and Figure 7In this embodiment, the clamping and rotating mechanism 53 includes a hollow block 531 fixedly connected to the inner surface of the slider 524, the left end of the hollow block 531 penetrates and extends to the right end of the hollow block 531 and is slidably connected with a rectangular rod 532, the outer surface of the rectangular rod 532 is fixedly connected with a connecting block 533 slidably connected to the inner surface of the hollow block 531, the right end of the connecting block 533 is fixedly connected with a spring 1 534 fixedly connected to the right part of the inner surface of the hollow block 531, the right end of the rectangular rod 532 is fixedly connected with a round block plate 535, the inner surface of the round block plate 535 is rotatably connected with a round rod 536, the right end of the round rod 536 is fixedly connected with a clamping plate 537, and the inner surface of the clamping plate 537 is linearly and equidistantly distributed and fixedly connected with a plurality of springs 2 538, and the upper ends of the plurality of springs 2 538 are commonly fixedly connected with a limit plate 539 slidably connected to the inner surface of the clamping plate 537.

[0040] For further information, see Figure 4 , Figure 6 and Figure 7 In this embodiment, the left end of the round rod 536 is fixedly connected to a gear 5310, the upper end of the base 1 is fixedly connected to an extrusion plate 5311, and the upper end of the extrusion plate 5311 is fixedly connected to a rack 5312 meshing with the gear 5310.

[0041] During the implementation process, the side of the current transformer body 7 with the connection pin 8 is facing upward and inserted into the space formed by the two clamping plates 537. At this time, the current transformer body 7 will squeeze the limit plate 539 upward and put the spring 2 538 in a stretched state, so that the current transformer body 7 can be effectively limited up and down, and then the right end output end of the dual-axis motor 526 is started to drive the rotating rod 1 521 to rotate through the coupling. Since the conveyor belt 523 and the transmission wheel 522 are wound and connected, the conveyor belt 523 can drive the slider 524 to slide backward on the inner surface of the slide groove 525, driving the current transformer body 7 to move backward. During the movement, the rectangular rod 532 will be squeezed by the squeezing plate 5311. The spring 1 534 is in a stretched deformation state, so that the rectangular rod 532 pushes the round block plate 535 to move closer to the middle to clamp and fix the current transformer body 7. The clamping and fixing operation of the current transformer body 7 can be realized during the transportation process, and it is no longer necessary to manually fix it, which can improve the working efficiency and accuracy of fault detection.

[0042] Secondly, after the fault detection is completed, when the current transformer body 7 moves forward, when it moves to the front of the extrusion plate 5311, the rectangular rod 532 is no longer squeezed, and moves away from each other under the tensile reaction of the spring 1 534, so that the current transformer body 7 is no longer clamped and fixed.

[0043] For further information, see Figure 4 and Figure 8In this embodiment, the positioning mechanism 54 includes a fixing plate 541 fixedly connected to the outer surface of the round rod 536, a telescopic rod 542 is fixedly connected to the right end of the fixing plate 541, a locking block 543 is fixedly connected to the right end of the telescopic rod 542, a spring 3 544 is sleeved on the outer surface of the telescopic rod 542, and the two ends of the spring 3 544 are respectively fixedly connected to the left end of the locking block 543 and the right end of the fixing plate 541, an arc groove 545 is provided at the left end of the round block plate 535, and the arc groove 545 is provided with two locking grooves 546 with an angle of 90 degrees, and the size and shape of the inner surface of the locking groove 546 are adapted to the size and shape of the outer surface of the locking block 543.

[0044] During the implementation process, when the current transformer body 7 moves backward, after the gear 5310 is meshed with the rack 5312, the round rod 536 will be driven to rotate 90 degrees on the inner surface of the round block plate 535, so that the clamped current transformer body 7 can be rotated 90 degrees and be in a vertical state with the base 1. During the rotation of the round rod 536, the fixed plate 1 541 will be driven to rotate, and the blocking block 543 will move away from the upper blocking groove 546 under the cooperation of the telescopic rod 542 and the spring three 544, and slide on the inner surface of the arc groove 545. When it moves to the blocking groove 546 at the lower part, the blocking block 543 will enter the blocking groove 546 under the cooperation of the telescopic rod 542 and the spring three 544, and fix the current transformer body 7 after rotating 90 degrees. During the cleaning operation and fault detection operation, the current transformer body 7 will not be offset in position, thereby improving the accuracy of fault detection.

[0045] The front and rear sides of the above-mentioned locking block 543 are both arc surfaces, and the sides of the two arc-shaped grooves 545 that are close to each other are also arc surfaces.

[0046] For further information, see Figure 4 and Fig. 9 In this embodiment, the detection protection mechanism 55 includes a second fixing plate 551 fixedly connected to the middle side of the rear portion of the upper end of the base 1, and conductive columns 552 are fixedly installed symmetrically on the inner surface of the second fixing plate 551. The front ends of the two conductive columns 552 are fixedly connected to conductive sheets 553. The lower end of the second fixing plate 551 penetrates and extends to the upper end of the second fixing plate 551 and is slidably connected to a protection plate 554. The lower end of the protection plate 554 is fixedly connected to an inclined block 1 555. The outer surface of the protection plate 554 is sleeved with a spring 4 556. The two ends of the spring 4 556 are respectively fixedly connected to the upper end of the inclined block 1 555 and the lower end of the second fixing plate 551. The ends of the two sliders 524 close to each other are commonly fixedly connected to the inclined block 2 557. The two conductive columns 552 are respectively connected to the detection box 4 through wires.

[0047] As can be seen from the above, after the current transformer body 7 can rotate 90 degrees, it will continue to move backwards, and in the process of movement, it will drive the inclined plane block 2 557 to move backwards. The squeezing of the inclined plane block 1 555 will push the protective plate 554 to move upwards, so that the two conductive columns 552 and the conductive sheet 553 leak out, and then the two connecting pins 8 on the current transformer body 7 will be tightly attached to the two conductive sheets 553, so that the outer surface of the connecting pins 8 can be completely in contact with the conductive sheet 553, and then the two contacts of the detection box 4, one output and one input, provide current to the current transformer body 7 through the wire input, and the current passes through the current transformer body 7 and returns to the detection box 4 from the output end. The conductor is judged whether it is faulty by the feedback current signal, so that the conductive sheet 553 can be protected when no longer detected, to prevent dust and debris from adhering to the front end of the conductive sheet 553, resulting in inaccurate fault detection, and at the same time, it can prevent the user from accidentally touching it and causing a safety accident.

[0048] The conductive posts 552 and conductive sheets 553 mentioned above are both existing mature detection technologies and parts. In this solution, their conductive function is utilized, and the distance between the two conductive posts 552 changes with the distance between the actual connection pins 8. Their structure and principle will not be elaborated again.

[0049] Embodiment 2: Based on Embodiment 1, this embodiment adds a cleaning component 6 for cleaning the debris attached to the outer surface of the terminal pins 8 on the current transformer body 7 before detection, so as to achieve the purpose of cleaning the debris attached to the outer surface of the terminal pins 8 on the current transformer body 7 before detection.

[0050] Specifically, in order to clean the debris attached to the outer surface of the connection pin 8 on the current transformer body 7 before detection, refer to Figure 4 and Fig.10 In this embodiment, the cleaning component 6 includes a rotating rod 61 fixedly connected to the left output end of the dual-axis motor 526 through a coupling, a cleaning mechanism 62 is provided at the upper end of the base 1, and a blower mechanism 63 is provided at the left end of the base 1.

[0051] For further information, see Figure 4 and Fig.10 In this embodiment, the cleaning mechanism 62 includes a fixing frame 621 symmetrically fixedly connected to the upper end of the base 1, the inner surfaces of the two fixing frames 621 are rotatably connected to a transmission rod 1 622, the left part of the outer surface of the transmission rod 1 622 and the outer surface of the rotating rod 2 61 are fixedly connected to a pulley group 1 623, and a soft brush 624 is fixedly installed in the middle part of the outer surface of the transmission rod 1 622.

[0052] For further information, see Figure 4 and Fig.10In this embodiment, the hair dryer mechanism 63 includes a circular hole frame 631 fixedly connected to the left end of the base 1, the left end of the circular hole frame 631 penetrates and extends to the left part of the inner surface of the circular hole frame 631 and is rotatably connected to a second transmission rod 632 rotatably connected to the left end of the base 1, the outer surface of the second transmission rod 632 is fixedly connected to a fan blade 633, the outer surface of the second transmission rod 632 and the outer surface of the first transmission rod 622 are jointly fixedly connected to a pulley set 2 634, and the rear part of the inner surface of the circular hole frame 631 penetrates and extends to the outer surface of the circular hole frame 631 and is fixedly connected to an air outlet pipe 635.

[0053] During the implementation process, when the current transformer body 7 moves backward, the left end output end of the dual-axis motor 526 is started to drive the rotating rod 2 61 to rotate through the coupling, and the transmission rod 1 622 is driven to rotate under the transmission action of the pulley group 1 623, so that the soft brush 624 of the transmission rod 1 622 rotates to clean the dust and debris attached to the terminal pin 8. At the same time, the rotation of the transmission rod 1 622 will be transmitted through the pulley group 2 634 to drive the fan blade 633 to rotate, and the air is sucked into the air outlet 635 through the circular hole frame 631 to blow the terminal pin 8 during the cleaning process, thereby improving the cleaning effect and preventing dust and debris from interfering with the current sensor and the distribution of the electromagnetic field, resulting in a decrease in the sensitivity of the current transformer body 7, thereby affecting the accuracy of the detection result. Cleaning dust and debris can maintain the performance of the current transformer body 7 stable and extend its service life.

[0054] The pulley set 1 623 and the pulley set 2 634 mentioned above are both composed of two belts and pulleys.

[0055] The dual-axis motor 526 mentioned above is a mature driving technology device in the prior art, and is a mature driving technology means in the prior art. This solution utilizes its function of independently rotating on both sides, and can stop in time after rotating to a set number of circles, and its principle, structure and connection method will not be elaborated.

[0056] Working process: When in use, the current transformer body 7 is placed in the clamping and rotating mechanism 53, and then the conveying mechanism 52 drives the current transformer body 7 to move backward, and during the movement, the dust and debris attached to the outer surface of the terminal pin 8 are cleaned with the cooperation of the cleaning mechanism 62 and the blower mechanism 63. After the cleaning operation is completed, the current transformer body 7 is flipped 90 degrees under the action of the clamping and rotating mechanism 53 and the positioning mechanism 54, so that the current transformer body 7 can be vertical to the base 1, and then the fault of the current transformer body 7 is detected by the detection and protection mechanism 55.
