Description

Technical Field

[0001] The present invention relates to the technical field of busbar installation, and in particular to a busbar wiring arrangement device and a wiring arrangement method for a power equipment cabinet. Background Art

[0002] The power equipment cabinet, also commonly known as the distribution cabinet, is an important part of the power equipment. Its main function is to distribute, control and protect the electric energy. It is a cabinet composed of a variety of equipment, including but not limited to switchgear, control equipment, metering equipment, protection equipment and power supply equipment.

[0003] Most electrical equipment placed inside the power equipment cabinet needs to be connected through busbars. Inside the power equipment cabinet, there are multiple circuit breakers arranged at equal distances, so that the maintenance space between each circuit breaker is relatively uniform, which is convenient for inspection and replacement. The busbars connected to the circuit breakers also need to be arranged at equal distances. The busbars arranged at equal distances form a regular inspection channel, so that the staff can more conveniently perform necessary inspections, tests and repairs during inspection and maintenance.

[0004] Chinese patent application CN115864267A discloses a busbar arrangement locking device for a power distribution cabinet, which fixes all the busbars to be connected through a locking portion, then moves the locking portion on the transverse fixing portion and fixes it, and then operates the adjustment portion to adjust the position between the two groups of transverse fixing portions; finally, after the adjustment is completed, it is fixed and adsorbed on the inner wall of the cavity of the power distribution cabinet, and then the busbar is connected to the electrical components to be connected.

[0005] The above patents and prior art also have the following defects:

[0006] The prior art cannot use equipment to automatically adjust the distance between each busbar based on the electrical equipment arranged at equal distances, so that the distance between each busbar matches the distance between each circuit breakers. In addition, the distance between each circuit breaker in different power equipment cabinets varies due to different system requirements. The prior art makes it difficult to adjust the distance between each busbar based on the different system requirements of different power equipment cabinets. If new electrical equipment needs to be added to the power equipment cabinet at a later stage to adapt to changes in system requirements, it is necessary to add a corresponding number of busbars and clamping devices for fixing the busbars. However, the number of clamping devices for fixing the busbars in the prior art is fixed, and new clamping devices cannot be added.

DETAILED DESCRIPTION

[0041] 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.

[0042] Example: Reference Figure 1-Figure 11 A busbar arrangement device is shown, comprising an electric equipment cabinet 1, wherein a plurality of circuit breakers 3 are installed side by side in a linear array inside the electric equipment cabinet 1, a busbar 4 is connected to the corresponding lower part of the circuit breaker 3, and the end of the busbar 4 away from the circuit breaker 3 is connected to other electric equipment (not shown in the figure), and a switch door 2 is installed on the front side of the electric equipment cabinet 1.

[0043] A load-bearing block 5 is detachably installed inside the power equipment cabinet 1, and mounting plates 51 are fixedly connected on both sides of the load-bearing block 5. Bolts are threaded on the mounting plates 51. The load-bearing block 5 is detachably connected to the power equipment cabinet 1 through the bolts on the mounting plates 51. A T-shaped slot 52 is provided on the front side of the load-bearing block 5, and both ends of the T-shaped slot 52 are connected to the outside of the load-bearing block 5. A clamping assembly 6 is slidably provided on the front side of the load-bearing block 5.

[0044] The clamping assembly 6 can clamp the busbar 4. The clamping assembly 6 includes a clamping plate 61. A T-shaped block 65 is fixedly connected to the back of the clamping plate 61. The T-shaped block 65 is slidably arranged inside the T-shaped slot 52. An upper clamping slot 62 is opened in the middle of the front side of the clamping plate 61. The upper clamping slot 62 is adapted to the busbar 4. Matching slots 63 are opened on the front side of the clamping plate 61 and near its two sides. A limiting plate 64 is rotatably connected inside one of the matching slots 63. When the limiting plate 64 is rotated to match with the other matching slot 63, the busbar 4 can be limited. A threaded hole is opened on the limiting plate 64, and a threaded groove is opened on the other matching slot 63.

[0045] When the busbar 4 is in the upper clamping groove 62, the limiting plate 64 is then rotated. When the limiting plate 64 is rotated to cooperate with another matching groove 63, the busbar 4 is limited. Then, bolts are used to pass through the threaded holes of the limiting plate 64 and the corresponding threaded grooves on the matching grooves 63 in sequence to clamp and limit the busbar 4.

[0046] The bottom ends of the load-bearing block 5 are symmetrically fixedly connected with connecting plates 11, and an adjusting component 7 is installed between the two connecting plates 11. The adjusting component 7 can adjust the distance between two adjacent busbars 4 and make the distance between each busbar 4 consistent. The adjusting component 7 includes a bearing column 71 arranged under the load-bearing block 5, and both ends of the bearing column 71 are detachably connected with supporting columns 75, and the supporting columns 75 are threadedly connected to the corresponding connecting plates 11, and the supporting columns 75 penetrate the connecting plates 11. The two supporting columns 75 jointly support the bearing column 71, and the bearing column The same number of offset blocks 73 as the clamping plate 61 are slidably sleeved on 71, and a lower clamping groove 731 adapted to the busbar 4 is opened in the middle of the front side of the offset block 73. The offset block 73 is detachably connected to the corresponding clamping plate 61, and an adjusting spring 74 is arranged between two adjacent offset blocks 73. The two ends of the adjusting spring 74 are respectively abutted against the two offset blocks 73, and the adjusting spring 74 is sleeved on the bearing column 71. The bearing column 71 is symmetrically slidably sleeved with a slider 72, and the offset block 73 and the adjusting spring 74 are located between the two sliders 72, and the two sliders 72 can be close to each other.

[0047] The supporting columns 75 at both ends of the bearing column 71 are removed from the bearing column 71, and the offset blocks 73 and a certain number of adjusting springs 74 that are the same as the number of busbars 4 are added from the two ends of the bearing column 71, and the adjusting springs 74 are added between two adjacent offset blocks 73, and the clamping components 6 that are the same as the number of busbars 4 are gradually added from the two ends of the load-bearing block 5, so that the clamping plate 61 is connected to the corresponding offset block 73, and the upper clamping groove 62 is aligned with the lower clamping groove 731, and the two sliders 72 are close to each other. The two sliders 72 squeeze the offset block 73 between them, and the offset block 73 moves. Because there is an adjusting spring 74 between the two adjacent offset blocks 73, the force of each adjusting spring 74 is consistent, and the contraction amount is consistent, so that the spacing between each offset block 73 is consistent, until the spacing between each offset block 73 is the same as the spacing between each busbar 4, the operation of the two offset blocks 73 is stopped; then the supporting column 75 passes through the connecting plate 11 and is connected to the end of the bearing column 71 , support the bearing column 71, and then install the entire device to a specific position inside the power equipment cabinet 1, open the limit plate 64, and place each busbar 4 in the corresponding upper clamping groove 62 and lower clamping groove 731. After the two ends of the busbar 4 are respectively connected to the corresponding power equipment, use the clamping assembly 6 to clamp and limit the busbar 4, and then use bolts to fix the clamping assembly 6 on the load-bearing block 5. Because new circuit breakers 3 and busbars 4 will be added later, if the clamping assembly 6 that has been used is not fixed, when new circuit breakers 3 and busbars 4 are added later, the two sliders will move away from each other. Without the compression constraint of the adjustment spring 74, all the clamping assemblies 6 will move. Because the clamping assembly 6 is fixed to the busbar 4, the movement of the clamping assembly 6 will cause the busbar 4 to have a horizontal displacement, which may cause the busbar 4 to bend. Therefore, the clamping assembly 6 that has been used needs to be fixed, and the spacing between the busbar 4 added later and the adjacent busbar 4 remains unchanged.

[0048] When used for the first time, by cooperating with the adjustment component 7 and the clamping component 6, the spacing between each offset block 73 can be adjusted according to the distance between two adjacent circuit breakers 3, and the distance between each offset block 73 is adjusted by compressing the adjustment spring 74, and then the distance between each busbar 4 can be adjusted, which can meet the distance requirements between each busbar 4 in different power equipment cabinets 1. It should be noted that when new circuit breakers 3 and busbars 4 are added subsequently, the positions of the clamping components 6 and adjustment components 7 that have been used have been fixed by bolts and will not change. The subsequent addition process only involves position adjustment of the newly added clamping components 6 and adjustment components 7.

[0049] The end of the support column 75 close to the bearing column 71 is fixedly connected with a threaded rod 751, and the end of the bearing column 71 is provided with a threaded groove adapted to the threaded rod 751. The end of the support column 75 away from the bearing column 71 is fixedly connected with a handle 752. The outer side of the support column 75 and the position penetrating the connecting plate 11 are provided with a threaded portion, and the connecting plate 11 is provided with a threaded hole adapted to the threaded portion of the support column 75. When it is necessary to remove the support column 75 from the end of the bearing column 71, the handle 752 is rotated, and the handle 752 drives the support column 75 to rotate, so that the threaded rod 751 is separated from the threaded groove of the bearing column 71, and the threaded portion of the support column 75 is separated from the threaded hole of the connecting plate 11, and then the support column 75 is pulled out from the connecting plate 11.

[0050] The offset block 73 is L-shaped, and the offset block 73 is symmetrically threaded with a long screw 10, and the long screw 10 passes through the offset block 73. The top of the long screw 10 is threadedly connected to the clamping plate 61, and there is a specified distance between the top of the offset block 73 and the bottom of the clamping plate 61. When the offset block 73 needs to be connected to the corresponding clamping plate 61, the long screw 10 is used to connect the offset block 73 and the clamping plate 61. When the long screw 10 is assembled between the offset block 73 and the clamping plate 61, the long screw 10 is rotated and moved upward from the bottom of the offset block 73. When it is necessary to add new circuit breakers 3 and busbars 4 to adapt to changes in system requirements, the number of offset blocks 73 and clamping plates 61 can be easily disassembled and added. This design enables the busbar wiring device to adapt to different power configurations without large-scale modification or replacement of the entire device.

[0051] A power assembly 9 is arranged between the two connecting plates 11, and the power assembly 9 can realize the movement of the two sliders 72 closer to each other. The power assembly 9 includes a power motor 91, a double-headed screw 92, and a guide rod 93. The power motor 91 is fixedly connected to the side of one of the connecting plates 11, and the output end of the power motor 91 is fixedly connected to the double-headed screw 92. The two ends of the outer surface of the double-headed screw 92 are respectively provided with threads of opposite rotation directions. The end of the double-headed screw 92 away from the power motor 91 is rotatably connected to the corresponding connecting plate 11. The two sliders 72 are symmetrically threaded on the double-headed screw 92, and the double-headed screw 92 is located below the bearing column 71. A guide rod 93 is fixedly connected between the two connecting plates 11, and the guide rod 93 penetrates the two sliders 72. The guide rod 93 is used to realize the lateral linear movement of the slider 72. Start the power motor 91, and the output end of the power motor 91 drives the double-headed screw 92 to rotate, so that the two sliders 72 are closer to or farther away from each other under the guiding action of the guide rod 93.

[0052] A transverse transmission assembly 8 is provided on the side of the connecting plate 11 close to the slider 72, and a vertical transmission assembly 12 is provided on the side of the connecting plate 11 away from the slider 72. When the two sliders 72 move away from each other and the slider 72 slides on the supporting column 75, the slider 72 can drive the transverse transmission assembly 8 to move, and the transverse transmission assembly 8 can drive the vertical transmission assembly 12 to move. The transverse transmission assembly 8 and the vertical transmission assembly 12 cooperate with each other, and a fixed plate 721 is fixedly connected to the bottom of the slider 72.

[0053] The transverse transmission assembly 8 includes a rack 89 fixedly arranged at the bottom of the fixed plate 721, and the rack 89 can move horizontally with the fixed plate 721 and the slider 72. The connecting plate 11 is fixedly connected to a stabilizing plate 81 near the side of the slider 72 and near its bottom. The front side of the stabilizing plate 81 is rotatably connected to a driving shaft 82, and a driving gear 83 and a driving bevel gear 84 are fixedly sleeved on the driving shaft 82, and the driving bevel gear 84 is located in front of the driving gear 83. When the fixed plate 721 moves above the driving gear 83, the driving gear 83 can mesh with the rack 89. The connecting plate 11 is rotatably connected to a driven shaft 86 near the side of the slider 72 and near its bottom, and the driven shaft 86 is rotated from the driving shaft 82. The driven shaft 86 passes through the connecting plate 11, one end of the driven shaft 86 is fixedly connected with a driven bevel gear 85, the driven bevel gear 85 is meshed and connected with the driving bevel gear 84, the other end of the driven shaft 86 is fixedly connected with a transmission gear 88, a long pad 87 is fixedly connected to the side of the connecting plate 11 and located below the driven shaft 86, a first bearing groove adapted to the driven shaft 86 is provided on the top of the long pad 87, and the driven shaft 86 is rotatably arranged in the first bearing groove, a short pad is fixedly connected to the side of the stabilizing plate 81 and located below the driving shaft 82, a second bearing groove adapted to the driving shaft 82 is provided on the top of the short pad, and the driving shaft 82 is rotatably arranged in the second bearing groove. The long pad 87 and the short pad provide a stable support platform for the driven shaft 86 and the driving shaft 82, respectively, to increase the stability of the rotation of the driven shaft 86 and the driving shaft 82.

[0054] When the two sliders 72 move away from each other, the slider 72 is separated from the bearing column 71, and the slider 72, the fixing plate 721, and the rack 89 slide on the supporting column 75 as a whole, the rack 89 is meshed with the driving gear 83, and the rack 89 drives the driving gear 83 to rotate, thereby causing the driving shaft 82, the driving gear 83, and the driving bevel gear 84 to rotate as a whole. The driving bevel gear 84 drives the driven bevel gear 85 to rotate by meshing with the driven bevel gear 85, thereby causing the driven bevel gear 85, the driven shaft 86, and the transmission gear 88 to rotate as a whole.

[0055] The vertical transmission assembly 12 includes an upper fixed shaft 126 and a lower fixed shaft 121 which are rotatably connected to the side of the connecting plate 11 away from the slider 72. The upper fixed shaft 126 is located directly above the lower fixed shaft 121. A steering gear 122 and a lower pulley 123 are fixedly sleeved on the lower fixed shaft 121. The steering gear 122 is meshed and connected with the transmission gear 88. An upper pulley 125 is fixedly sleeved on the upper fixed shaft 126. A belt 124 is connected between the upper pulley 125 and the lower pulley 123. The transmission gear 88 drives the steering gear 122 to rotate. The transmission gear 88 rotates in opposite directions to the steering gear 122. The steering gear 122 drives the lower fixed shaft 121 and the lower pulley 123 to rotate. The lower pulley 123 drives the upper pulley 125 to rotate through the belt 124. The upper pulley 125 drives the upper fixed shaft 126 to rotate.

[0056] The side of the connecting plate 11 away from the slider 72 is rotatably connected to a rotating rod, on which a clamping wheel is fixedly sleeved. The clamping wheel abuts against the belt 124 to tighten the belt 124, which has higher transmission efficiency and prevents the belt 124 from interfering with the supporting column 75.

[0057] A lifting piece 13 is symmetrically arranged above the bearing column 71, and an upper fixed shaft 126 passes through the connecting plate 11. The end of the upper fixed shaft 126 is fixedly connected to the lifting piece 13. A lifting groove 131 adapted to the bearing column 71 is provided on the lifting piece 13. The upper fixed shaft 126 can drive the lifting piece 13 to rotate downward 180°. When the lifting piece 13 rotates downward 180°, the outer wall of the bearing column 71 directly below the lifting piece 13 is placed in the lifting groove 131, and the two symmetrically arranged lifting pieces 13 jointly achieve the lifting effect of the bearing column 71. A support plate 132 is symmetrically fixedly connected to the bottom of the load-bearing block 5. A cylindrical hole is provided on the support plate 132 for the upper fixed shaft 126 to pass through.

[0058] When a new circuit breaker 3 needs to be added to adapt to changes in system requirements, the power motor 91 is started, and the output end of the power motor 91 drives the double-headed screw 92 to rotate, so that the two sliders 72 are guided by the guide rod 93 and move away from each other until the slider 72 abuts against the corresponding connecting plate 11. During the sliding of the slider 72 on the supporting column 75, the rack 89 is meshed with the driving gear 83, thereby driving the upper fixed shaft 126 to rotate 180° downward through the cooperation of the horizontal transmission assembly 8 and the vertical transmission assembly 12, and the upper fixed shaft 126 drives the lifting member 1 3 is rotated downward 180°, and the two lifting members 13 jointly achieve the lifting effect on the bearing column 71. Then, the support column 75 is disassembled from the end of the bearing column 71, and the support column 75 is separated from the connecting plate 11. New adjustment springs 74 and offset blocks 73 are added in sequence from the end direction of the bearing column 71. The newly added adjustment springs 74 and offset blocks 73 are located between the end surface of the bearing column 71 and the side surface of the lifting member 13. New clamping components 6 are added from the end direction of the load-bearing block 5. The number of new clamping components 6 is the same as the number of new offset blocks 73. The plate 61 is connected to the offset block 73, and the support column 75 is reinstalled to the end of the bearing column 71. The power motor 91 is started again to allow the two sliders 72 to approach each other. During the sliding process of the slider 72 on the support column 75, the rack 89 is meshed and connected with the driving gear 83, and the upper fixed shaft 126 is driven to rotate 180° upward through the cooperation of the horizontal transmission component 8 and the vertical transmission component 12. The upper fixed shaft 126 drives the lifting member 13 to rotate 180° upward to reset, and the lifting member 13 no longer achieves the lifting effect on the bearing column 71. At this time, there is a support column The body 75 supports the bearing column 71, and then the two sliders 72 squeeze the newly added offset block 73, and the offset block 73 moves. Under the action of the newly added adjustment spring 74, the spacing between each offset block 73 is made consistent, and the operation of the power motor 91 is stopped. The new busbar 4 is placed in the corresponding upper clamping groove 62 and lower clamping groove 731. After the two ends of the new busbar 4 are respectively connected to the corresponding power equipment, the corresponding clamping assembly 6 is used to clamp and limit the busbar 4, and then the new clamping assembly 6 is fixed to the load-bearing block 5 with bolts.

[0059] A wiring method for an electric power equipment cabinet comprises the following steps:

[0060] The supporting column 75 is removed from the bearing column 71 outside the power equipment cabinet 1, and the offset blocks 73 and a certain number of adjustment springs 74 are added from both ends of the bearing column 71, which are the same as the number of the busbars 4, and the clamping components 6 are gradually added from both ends of the load-bearing block 5, which are the same as the number of the busbars 4, so that the clamping components 6 are connected to the corresponding offset blocks 73;

[0061] The two sliders 72 are brought close to each other, and the two sliders 72 squeeze the offset block 73 between them, so that the offset block 73 moves. Under the action of the adjustment spring 74, the spacing between each offset block 73 is made consistent, until the spacing between each offset block 73 is the same as the spacing between each busbar 4, and the operation of the two offset blocks 73 is stopped;

[0062] The supporting column 75 is passed through the connecting plate 11 and connected to the end of the bearing column 71 , and then the load-bearing block 5 is installed to a specific position inside the power equipment cabinet 1 , and the clamping assembly 6 is used to clamp and limit the busbar 4 .
