[0021] Second, this invention uses a clamping arc block to initially clamp and fix the copper wire when it is inserted, utilizing the guiding inclined surface and the second spring. After the copper wire is wound, a series of linkage structures further clamp the copper wire, and the sliding plate slides to pull the copper wire, making the copper wire more tightly wound on the terminal block, effectively preventing poor contact, ensuring the stability and reliability of the electrical connection, and guaranteeing the accuracy of electrical measurement.

The use of digital measurement technology improves the authenticity and stability of the transmitter output, and can minimize the problem of oscillation or even tripping of the unit caused by fault current impact. Moreover, the normal output of the transmitter is not affected by the disconnection of a certain PT / CT, which greatly improves the stability of the system operation and provides a strong guarantee for the safe and stable operation of the generator-transformer unit.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] The present invention will be further described below with reference to embodiments.

[0035] Example: A generator-transformer integrated power measurement device, such as Figures 1-8 As shown, the device includes a generator-transformer unit 1, a copper wire 2 fixedly connected to the generator-transformer unit 1, a measuring device 3 connected to the copper wire 2, a power connection hole 4 provided on the measuring device 3, one end of the copper wire 2 slidably connected to the power connection hole 4, and a pair of clamping arc blocks 5 provided inside the power connection hole 4. The clamping arc blocks 5 are used to clamp the copper wire 2. A guide slope 6 is provided on one side of the clamping arc blocks 5. One end of the copper wire 2 abuts against the guide slope 6. With this design, when the copper wire 2 is inserted into the power connection hole 4, one end of the copper wire 2 will abut against the guide slope 6, causing the two clamping arc blocks 5 to slide to both sides, making it convenient for the copper wire 2 to be inserted into the power connection hole 4.

[0036] The measuring device 3 has a terminal block 7 fixedly installed inside. A fixing tube 8 is sleeved on the terminal block 7 and fixedly connected to the inside of the measuring device 3. A rotating ring 9 is rotatably connected to the fixing tube 8. A winding post 10 is fixedly connected to one side of the rotating ring 9. Through the design of the rotating ring 9 and the winding post 10, after the copper wire 2 is inserted into the power connection hole 4, the copper wire 2 will be in the middle between the terminal block 7 and the winding post 10. Then, by rotating the rotating ring 9, the winding post 10 will rotate together, so that the winding post 10 can contact the copper wire 2, so that the copper wire 2 can be wound on the terminal block 7. A protruding round block 11 is fixedly connected inside the rotating ring 9, and the lower end of the rotating ring 9 is fixedly connected to the inside of the measuring device 3.

[0037] The device can wrap the copper wire 2 around the terminal 7 by winding the winding post 10, and the wiring can be completed without additional operation.

[0038] It should be noted that the measuring device 3 is equipped with a signal input board, which integrates a signal input card, a core board, a display board, a motherboard, and a signal processing card. The display board also integrates a human-machine interface card.

[0039] The signal input card is equipped with an internal PT1 module, an internal PT2 module, an internal CT1 module, and an internal CT2 module. The internal PT1 module is used to receive and detect the three-phase voltage signal passed through the external PT1. The internal PT2 module is used to receive and detect the three-phase voltage signal passed through the external PT2. The internal measurement CT1 module is used to receive and detect the three-phase current signal passed through the external measurement CT1. The internal measurement CT2 module is used to receive and detect the three-phase current signal passed through the external measurement CT2.

[0040] The internal PT1, PT2, CT1, and CT2 modules of the signal input card are used to synchronously sample the voltage and current signals of the measurement group and the voltage and current signals of the protection group, and calculate the power of both groups simultaneously. Furthermore, this invention employs digital measurement technology, which can improve the accuracy and stability of the transmitter output, minimizing the risk of oscillations or even tripping caused by fault current surges. Even if a PT / CT experiences a wire break, it will not affect the normal output of the transmitter, greatly improving the stability of the system operation.

[0041] A support ring 12 is fixedly installed at the upper end of the rotating ring 9. The support ring 12 is designed to support the copper wire 2. The winding post 10 is slidably connected to the outer side of the support ring 12. A support rod 13 is provided at one end of the winding post 10. A control slope 14 is provided on one side of the support rod 13. The control slope 14 is designed to guide the copper wire 2 when it is inserted into the measuring device 3, so that the copper wire 2 can be tilted up. This prevents the winding post 10 from contacting the copper wire 2 in the middle section of the measuring device 3 when it rotates around the terminal post 7.

[0042] The rotating ring 9 has a spiral groove 15 and a straight slide groove 16. The spiral groove 15 and the straight slide groove 16 are fixedly connected. The raised round block 11 is slidably connected to the spiral groove 15 and the straight slide groove 16. The spiral groove 15 guides the raised round block 11, so that the rotating ring 9 can rotate, and the winding column 10 can wind the copper wire 2 onto the terminal 7.

[0043] A circular groove 17 is provided on the lower side of the rotating ring 9, and a rack 18 is slidably connected inside the circular groove 17;

[0044] The measuring device 3 has a power motor 19 fixedly installed inside. The power output end of the power motor 19 is fixedly connected to a gear 20. The gear 20 meshes with one side of the rack 18. Through the design of the power motor 19 and the gear 20, power can be provided to the rack 18, so that the rack 18 can drive the rotating ring 9, and the rotating ring 9 can slide on the fixed tube 8.

[0045] One end of the rack 18 is fixedly connected to an abutment rod 21, which is slidably connected to the inside of the measuring device 3. The other end of the abutment rod 21 is provided with a round abutment block 22, which is slidably connected to a limiting groove 23. The limiting groove 23 is designed to limit the position of the abutment rod 21 and the round abutment block 22 to prevent displacement. The limiting groove 23 is opened inside the measuring device 3.

[0046] The measuring device 3 has a limiting groove 24 inside, and a sliding plate 25 is slidably connected inside the limiting groove 24. The limiting groove 24 can limit the position of the sliding plate 25, so that the sliding plate 25 can slide within a predetermined trajectory. A first spring 26 is provided between the sliding plate 25 and the measuring device 3. The design of the first spring 26 can provide power for the subsequent reset of the sliding plate 25.

[0047] The sliding plate 25 is provided with a guide groove 27, which is slidably connected to the clamping arc block 5. The guide groove 27 is designed to limit the position of the clamping arc block 5 and prevent position deviation during sliding. A second spring 28 is fixedly connected between the two clamping arc blocks 5. The second spring 28 is designed to provide power for the subsequent reset of the clamping arc block 5. At the same time, when the clamping arc block 5 clamps the copper wire 2, the clamping arc blocks 5 on both sides can slide towards the position of the copper wire 2 under the tension of the second spring 28, so that the clamping arc block 5 can clamp the copper wire 2. One end of the clamping arc block 5 is provided with an abutment slope 29.

[0048] The measuring device 3 has a sliding groove 30 inside, and a control rod 31 is slidably connected inside the sliding groove 30. The design of the sliding groove 30 can limit the position of the control rod 31 and prevent the position of the control rod 31 from deviating. One end of the control rod 31 is used to abut against the inclined surface 29.

[0049] The other end of the control lever 31 is provided with a control ramp 32, which is used to abut against the round block 22. The control lever 31 can slide by abutting against the control ramp 32 by the round block 22.

[0050] The fixed tube 8 is provided with a control groove 33 and an abutment groove 34, which are connected to each other. The control groove 33 has the same shape as the spiral groove 15, and the abutment groove 34 has the same shape as the straight groove 16. A sliding ball rod 35 is slidably connected in the control groove 33 and the abutment groove 34. The other end of the sliding ball rod 35 abuts against an abutment block 36. A sliding rod 37 is fixedly connected to the abutment block 36. The other end of the sliding rod 37 is fixedly connected to the support rod 13. The other end of the sliding rod 37 abuts against a return spring 38, which is located inside the winding column 10.

[0051] When it is necessary to test the power of generator-transformer unit 1, the copper wire 2 on generator-transformer unit 1 is inserted into the power connection hole 4. It should be noted that the outer insulation layer of the copper wire 2 inserted into the measuring device 3 needs to be peeled off. When the copper wire 2 slides into the power connection hole 4, it will come into contact with the guide slope 6 on the clamping arc block 5. Because the copper wire 2 has a certain hardness, it will cause the clamping arc block 5 to slide to both sides. While the clamping arc block 5 slides to both sides, it will pull the second spring 28, causing the second spring 28 to deform. This allows the clamping arc block 5 to clamp and fix the copper wire 2 under the action of the second spring 28. The copper wire 2 will pass over the support rod 14. When the copper wire 2 reaches the appropriate position, the power motor 19 is started. The power motor 19 drives the gear 20 to rotate, allowing the rack 18 to slide.

[0052] It should be noted that the elastic force of the second spring 28 is insufficient to deform the copper wire 2, thus preventing the copper wire 2 from bending.

[0053] See Figure 7 At this time, the rack 18 can drive the rotating ring 9 to slide upward. While the rotating ring 9 slides upward, it drives the protruding round block 11 to slide inside the spiral groove 15. When the protruding round block 11 slides inside the spiral groove 15, it will drive the sliding ball rod 35 to slide inside the control groove 33. Through the guidance of the spiral groove 15 on the protruding round block 11, the protruding round block 11 can drive the winding column 10 to rotate around the terminal 7. At the same time, as the rotating ring 9 and the winding column 10 continue to slide upward, they will be supported by the support rod 13 and move upward together. Thus, the winding column 10 and the support rod 13 can drive the copper wire 2 to wind around the terminal 7 one round after another. Through this design, the copper wire 2 can be tightly wound on the terminal 7 to prevent poor contact.

[0054] It should be noted that the copper wire 2 inserted into the measuring device 3 is wound around the terminal 7 a sufficient number of turns.

[0055] As the rack 18 slides upwards, it drives the abutment rod 21 and the round abutment block 22 to slide upwards together. After the copper wire 2 is wound, the raised round block 11 slides to the junction of the spiral groove 15 and the straight groove 16. At this point, the round abutment block 22 slides to the control inclined block 32, where it contacts the inclined surface. Then, the rack 18 continues to drive the abutment rod 21 and the round abutment block 22 upwards, at which point the round abutment block 22 contacts the inclined surface of the control inclined block 32. (See...) Figure 5 The circular abutment 22 abuts against the control ramp 32, causing the control ramp 32 to slide to the right. This rightward sliding of the control ramp 32 causes the control lever 31 to slide to the right as well. The control lever 31 then abuts against the abutment ramps 29 on both sides. Figure 6 By controlling the contact of the abutment rod 31 with the contact slope 29, the clamping arc blocks 5 on both sides move closer to the middle, so that the clamping arc blocks 5 can clamp the copper wire 2 more tightly.

[0056] When the protruding circular block 11 slides within the straight groove 16, the sliding rod 35 slides within the contact groove 34. Figure 4The sliding rod 35 slides to the right due to the contact with the sliding groove 34. As the sliding rod 35 slides to the right, it contacts the inclined surface of the contact block 36, causing the contact block 36 to drive the sliding rod 37 to slide downwards. As the sliding rod 37 slides downwards, it pulls the return spring 38, causing the return spring 38 to deform. At the same time, the sliding rod 37 drives the support rod 13 to slide downwards. The downward sliding of the support rod 13 can compress the copper wire 2, making the copper wires 2 come into close contact and allowing the copper wires 2 to be more tightly wound on the terminal 7.

[0057] It should be noted that when the control ramp 32 drives the control lever 31 to contact the inclined surface 29, initially the sliding plate 25 will not slide under the action of the first spring 26, as the first spring 26 has sufficient elasticity. After the inclined surface 29 drives the clamping arc block 5 to clamp the copper wire 2, the positions of the clamping arc block 5 and the inclined surface 29 are fixed, and the control lever 31 can no longer push the clamping arc block 5 to slide. Only when the control ramp 32 continues to drive the control lever 31 to slide will the sliding plate 25 and the clamping arc block 5 slide together toward the entrance of the power connection hole 4. Through this design, the sliding plate 25 can slide while the copper wire 2 slides, allowing the copper wire 2 to slide together. After being wound around the terminal 7, the copper wire 2 is pulled to make it more tightly wound around the terminal 7, preventing poor contact later. When it is necessary to remove the copper wire 2 from the power connection hole 4, simply start the power motor 19 to make the rotating ring 9, the winding post 10, the raised round block 11, the rack 18 and the control wedge 32 slide downward, so that the clamping arc block 5 reduces the clamping force on the copper wire 2. Then, after the rotating ring 9 has completed its reset, the copper wire 2 can be pulled out from the power connection hole 4 by pulling it. It should be noted that only when the pulling force of the copper wire 2 reaches a certain level can the copper wire 2 be pulled out, and at the same time, not too much force is needed to prevent damage to the terminal 7.

[0058] In this embodiment: the spiral groove 15 guides the raised circular block 11, enabling the rotating ring 9 to drive the winding column 10 to rotate, allowing the winding column 10 to rotate around the terminal 7. The rotation of the winding column 10 winds the copper wire 2 around the terminal 7. Simultaneously, the design of the clamping arc block 5 clamps the copper wire 2, preventing excessive copper wire 2 from being wound into the measuring device 3 during winding. After the copper wire 2 is wound, the design of the straight sliding groove 16 allows the rack 18 to drive the abutment rod 21 and the circular abutment block 22 to continue sliding upwards, allowing the clamping arc block 5 to clamp the copper wire 2. Then, the sliding plate 25 pulls the copper wire 2, allowing it to be wound more tightly around the terminal 7, preventing poor contact.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
