Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1-6, the entire power distribution system of the present invention needs to be disposed within a cabinet, and a large ac low voltage power distribution system typically comprises 30 to 40 more distribution panels; the distribution panel comprises a generator control panel, a bridging panel, a separation panel, a load panel and the like. In a power distribution system, the largest number of load panels are used, and the load panels are distribution panels for controlling the start and stop of loads. The load screen is divided into an upper half 100 and a lower half 200. As shown in fig. 1-2, the upper half 100 and the lower half 200 of the load screen typically house two rows of load switches 3 (e.g., molded case circuit breakers 3), each row comprising a plurality of (e.g., two to five) molded case circuit breakers 3. The position of the molded case circuit breaker 3 needs to be fixed through a load switch mounting bracket 2, two sides (length direction) of the load switch mounting bracket 2 are fixed on a frame 1 of an outside distribution board, and various molded case circuit breakers 3 are fixed in the middle part in the frame 1 of the load board. It should be noted that the lower half of the isolation screen is similar to the load screen, and the generator control screen, the crossover screen, and the upper half of the isolation screen are different from the load screen, and are common knowledge in the art, and are not described herein.
As shown in fig. 1-9, the invention provides a bus three-dimensional arrangement method in a large-scale low-voltage alternating current power distribution system based on a three-dimensional model, wherein the bus three-dimensional model is realized by adopting three-dimensional software SolidWorks. The three-dimensional software performs a preliminary simulation of the frame structure and busbar arrangement of the distribution panel of the large-sized low-voltage alternating-current distribution system according to design requirements, and the preliminary simulation process mainly comprises assembly box body frames, assembly components and busbar arrangement, and specifically comprises: firstly, preassembling a frame of a main power distribution system, adding components and fixing supports required by a bus bar, then designing the whole main bus bar, fully considering detailed problems such as length, bending, perforating and the like of the bus bar in a three-dimensional model of the power distribution system, and finally outputting designed bus bar model data to actual production equipment.
The invention relates to a bus three-dimensional arrangement method in a large-scale low-voltage alternating current power distribution system based on a three-dimensional model, which specifically comprises the following steps:
s1, carrying out preliminary simulation based on a bus three-dimensional model to obtain a simulated bus arrangement result and outputting the bus arrangement result in a three-dimensional model drawing. The bus model drawing can be converted into an Excel form through AutoCAD to be output. The Excel table includes a punching shear table and a bending table, and information such as the number of processes, the busbar specifications, the punching X and Y positions, and the bending angle and position are displayed on the table, as shown in fig. 7 and 8.
S2, a novel copper bus bar processing machine (also called a bus bar processing machine) and copper bus bar bending equipment (also called a bus bar bending equipment) are adopted, corresponding software is utilized to read out the table, batch production can be achieved, workload is greatly reduced, and processing precision is improved. The method for reading the table specifically comprises the following steps: after the two machines open the table by using corresponding software, the blanking length of the copper bar (also called a busbar), the transverse axis position and the longitudinal axis position of each assembly hole and the selected die of each assembly hole are displayed on copper busbar bending equipment; meanwhile, the total bending number of the bus and the position of each bending die backer are displayed on the copper bus bending machine.
And S3, finally, correspondingly installing the bus bars into the distribution box according to the bus bar arrangement result.
As a preferred embodiment of the present invention, in the bus three-dimensional model design of step S1, the pre-simulation process further includes:
s11, assembling a frame of a main power distribution system: all single panels (single panels) in the main power distribution system are assembled, and a plurality of panels are closely placed together, so that each panel can be conveniently connected with a main bus bar according to target requirements in the follow-up process, and the layout of the whole frame structure is completed.
From the above, the whole design process of the present invention follows the principle of local-then-global, i.e. single-panel (single-panel) design, and each panel affects the overall layout. Because the structure of the frame of the distribution board can influence the arrangement of the bus bars, the mounting bracket adjusts the positions of the bus bars in the box body according to the needs, and various main switches and load switches can be correspondingly adjusted due to the positions of the mounting strip frames. Thus, the principle of partial-then-full design is followed throughout the design process.
S12, assembling components and parts and fixing supports: and components and fixing brackets used by the bus bars are respectively added on the frames of the single screens.
S13, converging and discharging the sample arrangement;
the step S13 further includes: s13-1, arranging all the buses on the single distribution panel; s13-2, connecting each distribution panel according to target requirements through the main bus-bar 7, and completing the layout of the whole frame structure.
In the step S13-1, in the single-screen design of the bus bars, the length, bending and opening size of each bus bar are fully considered, and a proper bus bar specification is selected by calculating the actual required current-carrying capacity; further comprising the following:
(1) After the position of the components (for example, the load switch and the molded case circuit breaker 3) on the single screen is fixed, the position of the upper bus bar 5 connected to the load switch is relatively easy to fix. The upper bus bar 5 is a bent bus bar, as shown in fig. 5, a first side of a bent portion of the upper bus bar 5 is connected with an upper terminal of the load switch and is fixed by a screw, and a second side of the bent portion of the upper bus bar 5 is fixedly connected to a horizontal bus bar 4 of each load switch. Correspondingly, the bending form of the upper connecting bar 5 of the busbar needs to be determined according to the load switch and the transverse busbar 4.
In this embodiment, each load switch on the single screen needs to be connected to the transverse busbar 4 of each load switch through the upper connection row 5, and then finally connected to the main busbar 7 through the connection row 6, as shown in fig. 3-6.
In addition, the transverse bus bar 4 and the upper end connecting bar 5 are respectively provided with holes, and the holes of the transverse bus bar 4 correspond to and coincide with the holes of the upper end connecting bar 5, so that the transverse bus bar 4 and the upper end connecting bar 5 are ensured to be smoothly installed and fixed. Therefore, the invention needs to measure the positions of the holes on the transverse busbar 4 and the upper connecting bar 5 respectively on the respective busbars, so that the two holes are completely overlapped, and the installation is convenient. If the distance from one side of the bus bar to the assembly hole is to be measured, the distance between the x axis, the y axis, the z axis and the straight line is displayed, and the length of each bus bar and the distance in each axis direction can be adjusted according to the measured data.
(2) From the above-mentioned transverse bus bar 4 to the main bus bar 7, various specifications are generally selected. For example, in the three-dimensional lofting process, it is required to select a single-split bus or a double-split bus according to the actual current capacity requirement (i.e., whether one bus is sufficient to meet the current requirement according to the current magnitude, and whether another bus needs to be added to share part of the current) and the actual spatial position.
(3) Illustratively, the length of the connection bars 6 is approximately half the length of the distribution panel, and care should be taken to take into account the orientation and location of the openings of the connection bars 6 to ensure connection between the connection bars 6 and the cross bars 4 and main bars 7.
(4) The distance between one end of the upper end connecting bar 5 and the position where the load switch is required to be opened is relatively measured in the three-dimensional lofting diagram (namely, the three-dimensional layout diagram of the bus bar and the components), and the size of the bus bar opening hole is required to be set according to relevant regulations (for example, a die with the diameter of 11mm is selected for the upper end connecting bar 5 connected with the load switch, a die with the diameter of 13mm is selected for the transverse bus bar 4, and a die with the diameter of 15mm is selected for the main bus bar 7, so that the assembly difficulty of workers can be reduced). The upper end connecting bar 5 of the load switch does not need too large holes, and the upper end connecting bar 5 after three-dimensional design can be accurately installed at the corresponding position, namely one end of the upper end connecting bar 5 is fixed on a binding post of the load switch, and the other end is fixed on the corresponding transverse bus bar 4.
(5) The length of the transverse bus bar 4 of the bus bars needs to be just fixed on the two end insulating bus bar frames 8, namely the length of the transverse bus bar 4 is equal to the length between the outer sides of the two side insulating bus bar frames 8 on the distribution board frame; if the length of the transverse bus bar 4 is too long, the transverse bus bar 4 can touch the frame body of the distribution board, and if the length of the transverse bus bar 4 is too short, the transverse bus bar cannot be fixed on the frame of the distribution board smoothly.
In the step S13-2, the method further comprises the following steps:
(1) Because each row of load switches on the single screen is required to be connected to the transverse bus bar 4 of each row of load switches through the upper end connecting bar 5 connected with the load switches, then the load switches are finally connected to the main bus bar 7 after being connected to the transverse bus bar 6, and then the connection between the main bus bars 7 on each distribution screen is realized through the connection between the main bus bars 7.
(2) The largest size of the main busbar 7 is also the most important consideration, and the position of each hole in the main busbar 7 needs to be accurately calculated. In principle, the main busbar 7 passing through the holes between each two distribution boards corresponds to the holes of the connection bars 6 in each single board, ensuring a smooth connection. Where there are some (e.g., one or two) holes in the main bus bar 7 that do not correspond to the locations of the holes in the single screen bus bar (i.e., the connector bar 6), the distribution board may experience difficulties in integrally connecting. Therefore, the invention places a plurality of distribution panels together through a three-dimensional model design, and can accurately obtain the position of each punching hole by using an internal measuring tool of three-dimensional software.
Because the traditional manual measurement method can not well control the lengths of all sections of the busbar and the positions where the sections should be bent, the problems of collision and the collision can not be avoided. In the invention, when designing the bus bar, because the elements related to the bus bar (such as the plastic shell circuit breaker) are already arranged at fixed positions, the transverse length and the longitudinal length of the installation space of the copper bar (also called the bus bar) can be accurately measured through the proportion of the view 1:1, and the bending position and the bending angle can be well judged by adopting three-dimensional lofting, so that the electrical safety distance between the bus bar and each part of the box body is ensured.
The bus model drawing can be converted into an Excel form to be output, wherein the Excel form comprises a punching shear form and a bending form. FIG. 7 is a schematic diagram of a bus punching shear table according to the present invention; the parameters are described as follows: model (1): the name of each bus is defined by distinguishing the assembly requirement; (2) number: the number of bus bars of this type is actually required; (3) row width: the width of the bus bar in the model, i.e. the width of the bus bar in the actual assembly; (4) thickness: the thickness of the bus bar in the model, i.e. the thickness of the bus bar in the actual assembly; (5) length: the blanking length required by actual production of the busbar without bending is provided in the model; (6) If the model is provided with an unfolding diagram of the bending busbar, the actual blanking length is provided. Specifically, X1: the first mounting hole is spaced from one lateral end of the busbar; y1: the first mounting hole is spaced a distance from the longitudinal direction of the busbar; m1: the code number of the die selected by the first assembly hole is M3; x2: the second mounting hole is located a distance laterally from the busbar; y2: the second mounting hole is spaced a distance longitudinally from the busbar; m2: the second mounting hole is selected to have a die code number M3.
FIG. 8 is a schematic diagram of a busbar bending table according to the present invention; the parameters are described as follows: (1) formula name: the name of each bus is defined by distinguishing the assembly requirement; (2) bending times: the number of times that the root busbar needs to be bent; (3) copper bar thickness: the thickness of the bus bar in the model, i.e. the thickness of the bus bar in the actual assembly; (4) copper bar width: the width of the bus bar in the model, i.e. the width of the bus bar in the actual assembly; (5) elastic compensation: for the busbar with stronger restoring force in the bending process, a allowance with a certain angle is required to be added so as to prevent angle errors, and the busbar can be understood as angle correction; (6) position 1: the position of the first bend of the busbar, which is needed to be folded from one end, namely the position of the mould backing; (7) Angle 1: the angle of the first bending; (8) position 2: the position of the second bend of the busbar which is required to be folded from one end, namely the position of the mould backing; (9) angle 2: the angle of the second bend. It should be noted that the tables of fig. 7 and 8 are merely examples, and the present invention is not limited thereto.
In summary, the conventional manufacturing method mainly adopts the methods of manual measurement, sketch drawing and bus line drawing. The invention can pre-assemble the large-sized low-voltage main switchboard once by using three-dimensional software, can see the effect after installation before actual production, can redesign some unsatisfactory designs, adjust the frame structure, the rack installation position, the switch fixing position and the busbar dimension specification, lead all errors to occur before production, reduce various errors which can be reduced during the design, and greatly improve the production efficiency and the economic benefit.
