Description

Technical Field

[0001] This invention relates to the field of electrical commissioning technology, and more specifically, to an electrical construction and commissioning device. Background Technology

[0002] Electrical commissioning mainly refers to the adjustment and testing of electrical equipment. In order to ensure the safe, reasonable and normal operation of electrical equipment and to avoid accidents that could cause economic losses to the country and casualties, commissioning work must be carried out. Only after passing electrical commissioning can electrical equipment be put into operation.

[0003] A search of Chinese patent CN217717837U reveals an electrical construction and debugging device, comprising a debugging instrument body and a fixing component. Handles are mounted on both ends of the debugging instrument body, and a debugging cable is connected to the right end of the top surface of the instrument body. A debugging clamp is attached to the bottom end of the debugging cable. A support plate is located on the right end of the front of the instrument body. The fixing component for cable management is located at the front end of the support plate and includes a sliding rod, clamps, a spring, and an insulating silicone plate. This electrical construction and debugging device, through the fixing component, allows the debugging cable to be pushed between two clamps during cable management. The clamps then slide towards both sides of the sliding rod under the pressure of the cable, adjusting the spacing between the two clamps. Afterward, when the cable approaches the sliding rod, the spring pulls the clamps on both sides, quickly clamping and fixing the cable, preventing it from becoming tangled due to looseness.

[0004] The existing electrical construction and commissioning equipment described above clamps the power terminals of the electrical equipment with a commissioning clamp, then energizes the equipment to test its operation. However, when testing electrical equipment, the power supply to the equipment is usually not missing a phase. For example, if the equipment is three-phase, the power supplied by the commissioning equipment is also three-phase. During actual operation, the equipment may experience a phase loss. If the phase loss lasts too long, it will affect the operation of the circuit's actuators, such as causing overcurrent. Therefore, it is necessary to commission and test the phase loss protection function of the electrical equipment. In addition, some actuators in the circuit, such as motors, may have forward and reverse rotation issues. It is necessary to supply three-phase power to the circuit to detect whether multiple motors are rotating in the same direction, thus avoiding inconsistencies in the forward and reverse rotation of multiple motors. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide an electrical construction and commissioning device. The technical problem to be solved by the present invention is that the electrical construction and commissioning equipment in the prior art cannot perform phase loss protection detection and forward and reverse rotation detection of the entire circuit, resulting in unsatisfactory commissioning effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electrical construction and debugging device, comprising: a debugging handle made of insulating material, wherein an annular groove is formed on the debugging handle, the inner wall of the annular groove forms a fixed shaft for the debugging handle, and three first conductive posts are inserted through one end of the handle, wherein one end face of the first conductive post is flush with the inner wall of the annular groove.

[0007] A converter head made of insulating material is movably mounted on a fixed shaft. Three transition conductive posts are inserted through the converter head, and two of the transition conductive posts are each fixed to an arc-shaped conductive plate at both ends of their axial direction. The arc center of the arc-shaped conductive plate is coaxial with the axis of the converter head.

[0008] Three second conductive posts are inserted through the other end of the adjustment handle, and a U-shaped clamping piece is fixed to one end of the adjustment handle. The end of the three second conductive posts away from the clamping piece is flush with the inner wall of the other side of the annular groove.

[0009] like Figure 1-9 As shown, the specific implementation method is as follows: The wiring studs of the electrical component are clamped by three clamping plates. The external power supply module energizes the three first conductive posts. Under normal energization, the three first conductive posts, transition conductive posts, and second conductive posts are one-to-one corresponding and electrically connected, so the electrical component can work normally. When the conversion head is rotated, one transition conductive post without the arc-shaped conductive plate is disconnected from the electrical connection with the first and second conductive posts, while the other two transition conductive posts with the arc-shaped conductive plate remain electrically connected to the first and second conductive posts. This allows the original three-phase power supply to be operated with a phase loss, causing the actuator of the electrical component's circuit to generate a phase loss, thereby detecting the phase loss protection effect of the circuit. In addition, by rotating the conversion head, the position of the three transition conductive posts can be adjusted, thereby allowing the forward and reverse rotation of the actuator to be detected. Since only the conversion head needs to be rotated to perform defect protection detection and actuator forward and reverse rotation detection, it saves time and effort, and can change the three-phase power supply under normal electrical component energization, thereby simulating the three-phase power loss state of the electrical component during actual operation.

[0010] In another preferred embodiment, the debugging handle has a first mounting hole for inserting the first conductive post, and the end face of the debugging handle has a wiring hole that communicates with the first mounting hole. Using the above solution, by threading a stud into the wiring hole, an external three-phase power module is connected to the stud via a cable, and the stud is electrically connected to the first conductive post, thereby electrically connecting the external three-phase power module to the three first conductive posts.

[0011] In another preferred embodiment, the two end faces of the transition conductive post are flush with the two end faces of the conversion head, the conversion head is provided with a second mounting hole for inserting the transition conductive post, and the end face of the conversion head is provided with an arc-shaped groove for engaging the arc-shaped conductive sheet, the arc-shaped groove communicating with the second mounting hole.

[0012] With the above solution, since the two end faces of the transition conductive post are flush with the two end faces of the converter head, and the arc-shaped conductive sheet is engaged in the arc-shaped groove, the end of the transition conductive post will not protrude from the end face of the converter head when the converter head is rotating, thus avoiding interference with the rotation of the converter head.

[0013] In another preferred embodiment, two clamping rods are symmetrically hinged along the axial direction of the end of the adjustment handle away from the conversion head. The length direction of the clamping rods forms an angle with the axial direction of the adjustment handle, and clamping plates are fixed to the upper ends of the two clamping rods. The two clamping rods are driven by a drive structure to swing so that the two clamping plates can move closer to each other.

[0014] Using the above scheme, the two clamping rods are driven to move closer to each other through the drive structure, thereby causing the two clamping plates to come together and clamp the opposite outer walls of the electrical components. This allows the debugging handle to be in a fixed state during debugging, and the clamping plates to stably clamp the wiring studs of the electrical components.

[0015] In another preferred embodiment, the driving structure includes:

[0016] A sliding sleeve is movably fitted onto the adjustment handle and forms a sliding engagement with the adjustment handle; two hinge rods are hinged to the sliding sleeve, and the ends away from the sliding sleeve are respectively hinged to two clamping rods;

[0017] An electromagnet is fixedly mounted on the adjustment handle and located between the sliding sleeve and the clamping rod; a spring is wrapped around the adjustment handle, and its two ends elastically abut against the electromagnet and the sliding sleeve respectively in the direction of elastic force.

[0018] Using the above scheme, an external low-voltage power supply module energizes the electromagnet, causing it to generate magnetism and a magnetic attraction force on the sliding sleeve. This drives the sliding sleeve to move towards the electromagnet, causing it to move upwards and compress the spring. Simultaneously, this causes the two hinge rods to move upwards, which in turn causes the clamping rods to swing along the hinge point with the adjustment handle. This allows the two clamping rods to move closer together at the hinge point with the adjustment handle, enabling the two clamping plates to come close together and clamp the opposite outer walls of the electrical component. This allows the adjustment handle to... It can stably connect with electrical components, thus preventing the clamping plates from detaching from the terminal studs on the electrical components, which would affect the debugging process of the electrical component circuit. After debugging, the power supply of the electromagnet is disconnected, the electromagnet loses its magnetism, and the spring changes from a compressed state to an extended state, which in turn drives the sliding sleeve to move downward, and drives the hinge rod to move downward, which in turn drives the sliding sleeve to move downward, and makes the two clamping plates move away from each other, thus realizing the loosening and loosening of the electrical components. The structure is simple and avoids affecting the electrical connection between the clamping plates and the terminal studs.

[0019] In another preferred embodiment, the three second conductive posts, with one end exposed from the adjustment handle, are collectively fitted with a plastic floating plate. Two pairs of insulating blocks are fixed to the plastic floating plate, with adjacent blocks respectively contacting the outer walls of the two straight sections of the clamping piece. When the two clamping rods approach each other, the floating structure drives the plastic floating plate to move towards the clamping piece, thereby causing the fixed blocks to press against the straight sections of the clamping piece, resulting in elastic deformation of the two straight sections of the clamping piece bringing them closer together.

[0020] Using the above scheme, when the two clamping rods approach each other, they drive the plastic floating plate to move towards the clamping piece. This causes the fixing block on the plastic floating plate to press against the outer walls of the two straight sections of the clamping piece, resulting in elastic contraction deformation of the clamping piece. This allows the clamping piece to clamp the terminal stud, preventing loosening and gaps between the clamping piece and the terminal stud. When the clamping rods move away from each other, the clamping piece recovers its elastic deformation, causing the plastic floating plate to move away from the clamping piece. This allows the clamping piece to disengage from the terminal stud. The structure is simple and can simultaneously clamp the terminal stud with the clamping piece while the clamping plate clamps the electrical component, thus preventing loosening between the terminal stud and the clamping piece.

[0021] In another preferred embodiment, the floating structure includes two rollers rotatably connected to both ends of the plastic floating plate, with the two rollers making rolling contact with the opposite outer walls of the two clamping rods. Using this scheme, when the two clamping rods move closer together, the rollers roll upwards on the outer wall of the clamping rods facing the clamping piece. During this rolling motion, the plastic floating plate moves upwards, causing the fixing block to press against the clamping piece, resulting in elastic contraction deformation of the clamping piece. The structure is simple.

[0022] In another preferred embodiment, the outer wall of the adjustment handle and the adapter head is provided with a marking structure for use.

[0023] By adopting the above scheme, a marking structure is set on the outer wall of the debugging handle and the converter head, so that the position of the converter head rotation can correspond to the position of the first conductive post or the second conductive post.

[0024] The technical effects and advantages of this invention are as follows:

[0025] 1. This invention, by setting up a converter head, transition conductive posts, a first conductive post, and a second conductive post, allows the first transition conductive post without arc-shaped conductive plates to disconnect from the first and second conductive posts when the converter head is rotated. The other two transition conductive posts with arc-shaped conductive plates remain electrically connected to the first and second conductive posts. This enables a phase loss operation of the original three-phase power supply, causing a phase loss in the actuators of the electrical components' circuits, thus detecting the phase loss protection effect of the circuit. Furthermore, by rotating the converter head, the positions of the three transition conductive posts can be adjusted, allowing for detection of the forward and reverse rotation of the actuators. Since only rotating the converter head is needed for defect protection detection and actuator forward / reverse rotation detection, it saves time and effort, and can change the three-phase power supply while the electrical components are normally powered, thereby simulating the phase loss state of the three-phase power supply of the electrical components during actual operation.

[0026] 2. The present invention provides a clamping rod, a clamping plate and a driving structure. The driving structure drives the two clamping rods to move closer to each other, thereby bringing the two clamping plates together and clamping the opposite outer walls of the electrical components. This allows the debugging handle to be in a fixed state during debugging, and the clamping plates to stably clamp the wiring studs of the electrical components.

[0027] 3. This invention, by setting up a plastic floating plate, a fixed block, and a floating structure, drives the plastic floating plate to move towards the clamping piece when the two clamping rods approach each other. This allows the fixed block on the plastic floating plate to press against the outer walls of the two straight sections of the clamping piece, causing the clamping piece to elastically contract and deform. This allows the clamping piece to clamp the terminal stud, preventing loosening and gaps between the clamping piece and the terminal stud. Furthermore, when the clamping rods move away from each other, the clamping piece recovers its elastic deformation, causing the plastic floating plate to move away from the clamping piece. This allows the clamping piece to disengage from the terminal stud. The structure is simple and can simultaneously clamp the terminal stud with the clamping piece when the clamping plate clamps the electrical component, thus preventing loosening between the terminal stud and the clamping piece.

[0028] 4. The present invention sets rollers to roll on the outer wall of the clamping rods. When the two clamping rods come close to each other, the rollers roll upward on the outer wall of the clamping rods on the side facing the clamping piece. When rolling, the plastic floating plate can be driven to move upward, thereby causing the fixed block to squeeze the clamping piece, causing the clamping piece to produce elastic contraction deformation. The structure is simple. Attached Figure Description

Detailed Implementation

[0039] 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 a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Figure 1-9As shown, this invention provides an electrical construction and commissioning device, including a commissioning handle 13 made of insulating material. The commissioning handle 13 is cylindrical, and an annular groove is coaxially formed on the commissioning handle 13. The inner wall of the annular groove forms a fixed shaft 17 for the commissioning handle 13, which is coaxial with the commissioning handle 13. Three first mounting holes 18 are arranged in an array along the axial direction at one end of the commissioning handle 13. Three first conductive posts 23 are inserted into the three first mounting holes 18, and one end face of the first conductive post 23 is flush with the inner wall of the annular groove. In addition, a wiring hole 15 is formed on the end face of the commissioning handle 13, which communicates with the first mounting holes 18. A stud made of metal material is threaded into the wiring hole 15, and an external three-phase power module is connected to the stud via a cable. The stud contacts the surface of the first conductive post, thereby electrically connecting the stud to the first conductive post, and thus electrically connecting the external three-phase power module to the three first conductive posts. An insulating converter head 12 is movably mounted on the fixed shaft 17. Three transition conductive posts 22 are passed through the converter head 12 and arranged in an array along the axial direction of the converter head 12. Additionally, two of the transition conductive posts 22 have arc-shaped conductive plates 21 fixed to their axial ends. The arc center of the arc-shaped conductive plate 21 is coaxial with the axis of the converter head 12. Three second conductive posts 19 are passed through the end of the adjustment handle 13 away from the converter head 12. U-shaped clamping plates 16 are welded to the ends of the three second conductive posts 19 extending out of the adjustment handle 13. During testing, the clamping plates 16 are respectively... The connector is inserted into the wiring port of circuit breaker 1. A wiring stud 2 is threaded into the wiring port of circuit breaker 1. The defective part in the middle of the clamping piece 16 engages with the wiring stud 2, and the surface of the clamping piece 16 contacts the wiring stud 2. This ensures that the clamping piece 16 and the wiring stud 2 are electrically connected. Additionally, the ends of the three second conductive posts 19 furthest from the clamping piece 16 are flush with the inner wall of the other side of the annular groove. Initially, the three second conductive posts 19, the transition conductive post 22, and the first conductive post 23 correspond one-to-one. Furthermore, the two end faces of the transition conductive post 22 are in contact with the end faces of the first conductive post 23 and the second conductive post 19, respectively. This allows the external three-phase power module to normally energize circuit breaker 1, enabling normal energization testing of the circuit containing circuit breaker 1. When it is necessary to simulate the transition of circuit breaker 1 from a normal energized state to a phase-loss energized state, the rotating part 12 can be manually rotated. As the rotating part 12 rotates, the three transition conductive posts rotate around the axis of the conversion head 12. Two transition conductive posts connected to the arc-shaped conductive plate 21 maintain electrical connection with the first and second conductive posts because the first and second conductive posts are in contact with the arc-shaped conductive plate 21. However, the other transition conductive post is not connected to the arc-shaped conductive plate 21, causing the first and second conductive posts to disconnect from the transition conductive post. This simulates the phase-loss state of circuit breaker 1. Furthermore, because it can directly transition from a normal energized state to a phase-loss state, it more conveniently simulates the actual three-phase power supply operation.This allows for the detection of whether the phase loss protection function of the circuit breaker is functioning correctly. Furthermore, by rotating the converter head, the positions of the three transition conductive posts alternate, enabling the detection of the forward and reverse rotation of actuators (such as motors) in the circuit where circuit breaker 1 is located. This facilitates the adjustment of the forward and reverse rotation of multiple actuators in the circuit. Additionally, the outer walls of the adjustment handle 13 and the converter head 12 are equipped with a matching marking structure 14. This marking structure can be configured as identification lines and indicator arrows. Three identification lines are engraved on the outer wall of the adjustment handle 13, each corresponding to one of the three second conductive posts. An indicator arrow is engraved on the outer wall of the converter head, with the arrow on the converter head corresponding to one of the identification lines. When rotating the converter head, by observing the alignment of the indicator arrow with any one of the identification lines, the connection status of the three first conductive posts, second conductive posts, and transition conductive posts can be easily observed and indicated during converter head rotation.

[0040] like Figure 6 , 7 As shown in Figure 8, since the two end faces of the transition conductive post 11 need to be ensured not to interfere with the rotation of the converter head 12 when the converter head 12 rotates, in this embodiment, the two end faces of the transition conductive post 22 are set to be flush with the two end faces of the converter head 12 respectively. In addition, the converter head 12 is provided with a second mounting hole 25 for the transition conductive post 22 to be inserted, and an arc groove 24 is provided on the end face of the converter head 12 for the arc conductive piece 21 to be engaged and installed. The arc groove 24 is connected to the second mounting hole 25. Since the two end faces of the transition conductive post 22 are flush with the two end faces of the converter head 12 respectively, and the arc conductive piece 21 is engaged in the arc groove 24, the end of the transition conductive post 22 will not be exposed on the end face of the converter head 12 when the converter head 12 rotates, thereby avoiding interference with the rotation of the converter head 12.

[0041] like Figure 1 , 2As shown in Figure 3, during the testing process, the clamping piece 16 needs to remain clamped to the wiring stud 2 on the circuit breaker 1 to prevent loosening between the clamping piece 16 and the wiring stud 2 during debugging and testing. Therefore, in this embodiment, two hinge seats 4 are provided at the end of the debugging handle 13 away from the converter head 12. Each of the two hinge seats 4 is hinged with two clamping rods 7. The two clamping rods 7 are symmetrically arranged along the axial direction of the debugging handle 13. In addition, the length direction of the clamping rods 7 forms an acute angle with the axial direction of the debugging handle 13, and a clamping plate 5 is fixed to the upper end of the two clamping rods 7. The clamping plate 5 is made of a material that can be Made of soft rubber, the adjustment handle 13 is fitted with a sliding sleeve 11, which slides freely on the handle 13. Two hinge rods 9 are hinged to the outer edge of the sliding sleeve 11, and the ends of the other two hinge rods 9, away from the sliding sleeve 11, are hinged to two clamping rods 7. An electromagnet 8 is fixedly mounted on the adjustment handle 13, located between the sliding sleeve 11 and the clamping rods 7. A spring 10 is wound around the adjustment handle 13, with its two ends elastically abutting against the electromagnet 8 and the sliding sleeve 7 respectively. The sliding sleeve 11 is powered by an external low-voltage power supply module, which in turn energizes the electromagnet 8, causing it to generate magnetism and attract the sliding sleeve 11. This drives the sliding sleeve 11 to move towards the electromagnet 8, causing it to move upward and compress the spring 10. Simultaneously, this causes the two hinge rods 9 to move upward, which in turn causes the clamping rods 7 to swing along the hinge point with the adjustment handle 13. This allows the two clamping rods 7 to move closer together along the hinge point with the adjustment handle 13, enabling the two clamping plates 5 to come close together and clamp the opposite outer walls of the circuit breaker 1, thus facilitating the adjustment. Handle 13 can be stably connected to circuit breaker 1, thus preventing the clamping piece 16 from detaching from the terminal stud 2 on circuit breaker 1, which would affect the debugging process of the circuit where circuit breaker 1 is located. After debugging, the power supply to electromagnet 8 is disconnected, electromagnet 8 loses its magnetism, and spring 10 changes from a compressed state to an extended state, thereby driving sliding sleeve 11 to move downward, and driving hinge rod 9 to move downward, which in turn drives sliding sleeve 11 to move downward, and makes the two clamping plates 5 move away from each other, realizing the loosening of the clamp on circuit breaker 1 to avoid affecting the electrical connection between clamping piece 16 and terminal stud 2; such as Figure 1 , 2As shown in Figures 3, 4, and 5, due to the thinness of the clamping plate 16, it may not be able to maintain a stable contact with the terminal stud 2 after long-term use, resulting in a gap between the terminal stud 2 and the contact surface of the clamping plate 16, thus affecting the debugging process. Therefore, in this embodiment, a plastic floating plate 6 is fitted together at the end of the three second conductive posts 19 that protrude from the debugging handle 13. The plastic floating plate 6 has through holes for the second conductive posts 19 to pass through freely, and the through holes and the second conductive posts 19 form a sliding fit. In addition, two pairs of fixing blocks 20 made of insulating material are fixedly connected to the plastic floating plate 6. The two fixing blocks 20 in each pair respectively abut against the outer wall of the two straight sections of the clamping plate 16. Each end of the plastic floating plate 6 is rotatably connected to a roller 3. The two rollers 3 respectively roll in contact with the outer wall of the two clamping rods 7 on opposite sides. When the clamping rods 7 clamp the outer wall of the circuit breaker 1, the side of the clamping rods 7 facing the clamping plate is inclined. When the two clamping rods 7 approach each other, the roller will roll on the clamping rods 7. Specifically, when the two clamping rods 7 approach each other, the roller 3 rolls upward on the outer wall of the clamping rod 7 facing the clamping piece 16. When rolling, it can drive the plastic floating plate 6 to move upward, so that the fixing block 20 on the plastic floating plate 6 can squeeze the outer wall of the two straight sections of the clamping piece 16, thereby causing the clamping piece 16 to undergo elastic contraction deformation, so that the clamping piece 16 can clamp. The terminal stud 2 prevents the clamping plate 16 from becoming loose or creating gaps. Additionally, when the clamping rods 7 move away from each other, the clamping plate 16 recovers its elastic deformation, causing the plastic floating plate 6 to move away from the clamping plate 16 and downwards. This allows the clamping plate 16 to disengage from the terminal stud 2. When the clamping plate 5 clamps the circuit breaker 1, the clamping plate 16 simultaneously clamps the terminal stud 2, thereby preventing the terminal stud 2 from becoming loose and ensuring the commissioning can proceed smoothly.

When the two clamping rods (7) are close to each other, the floating structure drives the plastic floating plate (6) to move towards the clamping piece (16), thereby causing the blocks (20) to squeeze the straight sections of the clamping piece (16), so that the two straight sections of the clamping piece (16) produce elastic deformation that brings them closer together.

7. An electrical construction and commissioning device according to claim 6, characterized in that, The floating structure includes two rollers (3) that are rotatably connected to both ends of the plastic floating plate (6), and the two rollers (3) respectively roll in contact with the opposite outer walls of the two clamping rods (7).

8. An electrical construction and commissioning device according to claim 1, characterized in that, The outer walls of the adjustment handle (13) and the adapter (12) are provided with marking structures (14) for use.
