Description

Technical Field

[0001] The invention belongs to the technical field of transformer detection, and in particular relates to a transformer detection device. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. It is mainly composed of an iron core and a coil. The winding connected to the power supply is called the primary coil, and the other winding is called the secondary coil. Before mass production of a new type of transformer, it is necessary to test the transformer samples to ensure that the transformer performance meets the standards. One of the testing steps is to test the windings.

[0003] During the production process of the transformer, the coil needs to be wound on both sides of the iron core, and according to the design standards of different transformers, the number of turns of the primary coil and the secondary coil needs to be precisely controlled. For example, a transformer coil turns measuring tool proposed in the authorization announcement number CN116047185A can adjust the length of the core base so that the core base can measure transformer coils of different sizes, thereby illustrating the importance of transformer coil turns detection.

[0004] In the process of winding transformer coils, due to unskilled workers, insufficient tool accuracy or lack of effective counting and monitoring measures, the actual number of turns may deviate from the design value, and the winding equipment may malfunction, such as counter failure, unstable tension control, etc., which will affect the accuracy of winding. The traditional detection method is to use inductance measurement method, using professional inductance measuring instruments to measure the inductance value of the coil, and according to the known core parameters, magnetic permeability, etc., combined with the theoretical relationship between inductance value and number of turns, calculate the number of turns and compare it with the standard number of turns. This detection method takes a certain amount of time, and after the calculation, it is necessary to re-test to verify the accuracy of the calculation, which leads to a reduction in transformer detection efficiency.

[0040] The connecting component 31 includes a second linear motor 311 and a bending frame 312, the second linear motor 311 is fixedly connected to the lower side wall of the mounting frame 1, the bending frame 312 is fixedly connected to the output end of the second linear motor 311, the upper side wall of the bending frame 312 is fixedly connected to a push rod 32, the right side walls of the plurality of detection boxes 221 are fixedly connected to a small electric push rod 33 through a bracket, the output end of the small electric push rod 33 is fixedly connected to a trigger switch 34, the working ends of the push rod 32 and the trigger switch 34 are fixedly connected to an arc block 35, the upper side wall of the bending frame 312 is fixedly connected to a micro electric push rod 36, the moving end of the micro electric push rod 36 is fixedly connected to a power-on block 37, and the detection box 22 The lower side wall of the mounting frame 1 is inlaid with a power-on plate 38, which is electrically connected to the electromagnetic block 222 through a rectifier.

When detecting transformers with different design standards, different detection components 22 can be selected according to the design standards of the transformer to detect the transformer, thereby greatly improving the scope of use and functionality of the detection device.

[0041] A laser marking pen 41 is fixedly connected to the center of the lower inner wall of the connection frame 2, and a target plate 42 is connected to the center of the upper wall of the iron core 132, which can assist the operator to place the transformer structure 13 to be tested to the set position.

[0042] The rear side wall of the clamping box 401 is fixedly connected to a positioning electric push rod 43 through a bracket, and the movable end of the positioning electric push rod 43 is fixedly connected to a positioning push plate 44, which can locate the position of the transformer structure 13 to be tested for easy clamping.

[0043] The operating principle of the present invention is now described as follows: the transformer structure 13 to be tested is placed on the upper surface of the clamping box 401, and then the laser marking pen 41 is turned on, and then the placement seat 131 is moved so that the light emitted by the laser marking pen 41 is aligned with the center position of the target plate 42. Then, the operator controls the positioning electric push rod 43 to work through an external button, and the positioning electric push rod 43 drives the positioning push plate 44 to move forward, so that the placement seat 131 and the positioning push plate 44 are in contact, and the placement seat 131 is preliminarily positioned. Then, an operator holds the placement seat 131 with his hand, and another operator sends a control instruction to the PLC controller 30 through the operation interface. After receiving the control instruction, the PLC controller 30 first controls the conductive block 10 to be electrically connected to the external power supply. The conductive block 10 is in contact with the conductive plate 11 in the initial state, and the conductive plate 11 and the clamping motor 5 are in contact with each other. The forward circuit is electrically connected, so that external current can be transmitted to the forward circuit of the clamping motor 5, so that the clamping motor 5 starts to work, and the clamping motor 5 drives the first threaded rod 402 to rotate, and drives the two first threaded cylinders 6 to move in a direction close to each other through threaded cooperation, and the two first threaded cylinders 6 drive the cross cylinder 8 and the clamping plate 12 to move through the bent plate 7, so that the clamping plate 12 and the placement seat 131 are in contact, and when the clamping plate 12 and the placement seat 131 are in contact, an interaction force will be generated between the clamping plate 12 and the placement seat 131, and the clamping plate 12 stops moving under the action of the interaction force, while the cross cylinder 8 will continue to move driven by the first threaded cylinder 6, so that the clamping plate 12, the moving frame 9 and the conductive block 10 move relative to each other until the conductive block 10 and the conductive plate 11 are separated, and the forward circuit of the clamping motor 5 will be disconnected, and at this time, a suitable extrusion pressure will be generated between the clamping plate 12 and the placement seat 131;

[0044] Then, the operator controls the first linear motors 161 on the left and right sides to work through the control interface, so that the first linear motors 161 on the left and right sides drive the arc-shaped metal cutters 20 to move to the top of the primary coil 14 and the secondary coil 15 respectively through the moving rod 19. Then, the operator manually rotates the second threaded rods 17 on the left and right sides to rotate the second threaded rods 17, and drives the two second threaded cylinders 18 to move through the threaded cooperation, so that the second threaded cylinders 18 drive the arc-shaped metal cutters 20 to move through the moving rod 19, so that the two arc-shaped metal cutters 20 move toward the direction close to the primary coil 14 or the secondary coil 15 respectively, so that the two arc-shaped metal cutters 20 are respectively located above the primary coil 14 or the secondary coil 15. Then, the operator controls the first linear motors 161 on the left and right sides to drive the arc-shaped metal cutters 20 to move to the top of the primary coil 14 or the secondary coil 15 respectively. The operating interface transmits a work instruction to the PLC controller 30. After receiving the work instruction, the PLC controller 30 controls the first linear motors 161 on the left and right sides to work, so that the first linear motors 161 on the left and right sides drive the arc-shaped metal cutters 20 on both sides to move downward to the set position, so that the two arc-shaped metal cutters 20 are respectively in contact with the primary coil 14 or the secondary coil 15, and the arc-shaped metal cutters 20 cut the insulating layer on the surface of the primary coil 14 or the secondary coil 15, and contact the internal conductor, and then the energy storage power supply 21 and the load lamp bead 3 are respectively electrically connected to the lower end of the primary coil 14 or the secondary coil 15 through the crocodile clip, and the alternating current inside the energy storage power supply 21 will pass through the arc on the right side. The shaped metal cutter 20 and the alligator clip are transmitted to the primary coil 14. When the alternating current in the energy storage power supply 21 passes through the primary coil 14 of the transformer, an alternating magnetic field will be generated in the iron core 132. This alternating magnetic field will pass through the secondary coil 15. The secondary coil 15 converts the energy of the alternating magnetic field generated by the primary coil 14 into electrical energy through electromagnetic induction, thereby generating a voltage. When the voltage is applied to both sides of the load lamp bead 3, a current will be generated in the load lamp bead 3, so that the load lamp bead 3 will light up. When the operator finds that the load lamp bead 3 lights up, he can select a suitable detection component 22 according to the setting of the transformer. For example, when the transformer to be detected can convert a 220V voltage into a low voltage of 22V, the operator can select a suitable detection component 22 according to the setting of the transformer. The operation interface controls the corresponding small electric push rod 33 to drive the trigger switch 34 to move downward to the set position, and then the operator controls the second linear motor 311 to work through the operation interface. The second linear motor 311 drives the push rod 32, the conductive slide 39 and the micro electric push rod 36 to move backward together through the bending frame 312. When the push rod 32 moves to the bottom of the corresponding small electric push rod 33, the push rod 32 will squeeze the corresponding trigger switch 34 through the arc block 35 on the surface of the push rod 32 and the corresponding trigger switch 34, so that the corresponding trigger switch 34 transmits an electrical signal to the PLC controller 30. After receiving the electrical signal, the PLC controller 30 will control the second linear motor 311 to stop working immediately.Then the PLC controller 30 controls the micro electric push rod 36 to work, so that the micro electric push rod 36 drives the power block 37 to move upward to the set position, so that the power block 37 contacts the power plate 38, and the power block 37 is electrically connected to the load lamp bead 3 through the conductive slide plate 39 and the conductive slide groove 40. The conductive plate 11 is electrically connected to the electromagnetic block 222 through the rectifier, and the other side of the electromagnetic block 222 circuit is electrically connected to the circuit of the load lamp bead 3. When the power block 37 contacts the power plate 38, the electromagnetic block 222 will be connected in parallel to the load lamp bead 3. The circuit of the electromagnetic block 222 is connected, so that the electromagnetic block 222 is energized to generate magnetic force, and the resistance value of the electromagnetic block 222 is fixed. The current generated by the electromagnetic block 222 will change with the change of the voltage of the load lamp bead 3. The electromagnetic block 222 will be energized to generate magnetic force, and the electromagnetic block 222 will attract the permanent magnet plate 24 to move, so that the permanent magnet plate 24 drives the electric contact plate 25 to move to the right to a certain position. After the second linear motor 311 stops working, the PLC controller 30 will delay for ten seconds to transmit the external current to the electric contact plate 25;

[0045] When the number of turns of the primary coil 14 and the secondary coil 15 meet the design standard, the permanent magnet plate 24 will drive the electric contact plate 25 to contact the electric contact block 28 under the action of magnetic attraction. After the electric contact plate 25 is powered on after a delay, the external current will be transmitted to the electric contact block 28. The electric contact block 28 is electrically connected to the buzzer 29 through the PLC controller 30. The external current will be transmitted to the PLC controller 30 through the electric contact block 28, and an electrical signal will be transmitted to the PLC controller 30. After receiving the electrical signal, the PLC controller 30 will control the buzzer 29 to work, reminding the operator that the detection of the transformer structure 13 to be tested is completed and the operator can take it out.

[0046] When the number of turns of the primary coil 14 increases, under the condition that the input voltage remains unchanged, according to the voltage ratio formula of the transformer: U P / U S =N P / N S (U P is the primary voltage, U S is the secondary voltage, N P is the number of primary turns, N S is the secondary turns), when the primary turns N P Increase, and the secondary turns N S When the numerator increases, the fractional value increases, that is, the secondary voltage U SThe current delivered to the circuit of the electromagnetic block 222 will be reduced, thereby reducing the magnetic attraction generated by the electromagnetic block 222. The permanent magnet plate 24 drives the electric contact plate 25 to move to the right, which shortens the distance that the electric contact plate 25 contacts the metal plate 27 on the left. The metal plate 27 on the left is electrically connected to the positive circuit of the first linear motor 161 on the right. The electric contact plate 25 is electrically connected to the external power supply. After the external current is delivered to the electric contact plate 25 after a delay, the external current will be delivered to the positive circuit of the first linear motor 161 on the right through the metal plate 27 on the left, so that the first linear motor 161 on the right drives the moving rod 19 and the arc-shaped metal cutter 20 on the right to move downward, so that the energy storage power supply 21 contacts the primary coil 14 at the lower part, and the number of turns of the primary coil 14 is reduced. Referring to the above formula, when the primary number of turns N P decreases, and the secondary turns N S When the denominator decreases, the fraction value increases, that is, the secondary voltage U S It will become larger. Referring to the above principle, the magnetic attraction of the electromagnetic block 222 will gradually increase, and the magnetic attraction of the permanent magnet plate 24 will increase. The permanent magnet plate 24 will drive the electric contact plate 25 to gradually move to the right until the electric contact plate 25 is separated from the metal plate 27 on the left and contacts the electric contact block 28. The first linear motor 161 on the right will stop working, and the buzzer 29 will start working to remind the operator to remove the transformer structure 13 to be tested. The operator can reduce the number of turns of the corresponding primary coil 14 by observing the number of turns of the damaged insulating layer on the surface of the primary coil 14. Similarly, when the number of turns of the secondary coil 15 increases, the first linear motor 161 on the left will drive the arc-shaped metal cutter 20 on the left to cut downward a certain number of turns of the secondary coil 15. The operator can reduce the number of turns of the corresponding secondary coil 15 by observing the number of turns of the damaged insulating layer on the surface of the secondary coil 15.
