Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of circuit breaker production lines, and in particular to an assembly line for a primary and secondary integrated pole-mounted circuit breaker. Background Technology
[0002] Primary and secondary integrated pole-mounted circuit breakers are one of the core components of outdoor distribution network systems. They are widely used in power distribution networks and play a vital role in connecting, demarcating, and disconnecting outdoor overhead lines. With the construction of new power systems and the deepening application of smart grids, distribution networks not only undertake the traditional task of receiving and distributing electrical energy from the main grid, but also, with the large-scale application of distributed renewable energy access, take on the role of integrating distributed energy sources and aggregating electrical energy to the main grid. It can be seen that the role of distribution networks in new power systems is becoming more important. Therefore, both the power grid and end users have put forward specific requirements for the integration of primary and secondary circuit breakers in distribution systems, especially for circuit breakers, which are core components, requiring more specific integration, standardization, and specialization.
[0003] Pole-mounted circuit breakers mainly consist of three major components: the operating mechanism, the fusion pole, and the electrical control system. Their main production processes include machining of mechanical transmission components, bending / welding / surface treatment of the mechanism box, final assembly, commissioning, and inspection / testing. In the traditional industrialization model of pole-mounted circuit breakers, the processes are distributed across different workshops or processes. For example, machining of mechanical transmission components is done in the precision machining workshop; machining of the mechanism box is done in the sheet metal (shearing, punching, and bending) workshop, welding workshop, and pre-treatment and surface treatment workshop; final assembly is done in the component and secondary wiring harness assembly workshop; joint commissioning is completed in the assembly room; and product inspection / testing is then transferred to the inspection area for further testing.
[0004] In summary, the manufacturing process of pole-mounted circuit breakers involves many processing steps and areas. Traditional discrete manufacturing processes often involve logistics arrangements, waiting, transfer registration, etc., resulting in lengthy processes, long transfer times, and long production delivery cycles, which causes confusion for both manufacturing and application units during the ordering and production process.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0031] Example 1
[0032] like Figures 1 to 5As shown, this embodiment provides a primary and secondary integrated pole-mounted circuit breaker assembly line, including a main transmission line 1 and several process stations. The process stations include a quick assembly station 2, a slow assembly station 3, a characteristic test station 4, a mechanical break-in station 5, and a factory test station 6. At least one pair of quick assembly stations 2 are symmetrically arranged on both sides of the main transmission line 1. At least two slow assembly stations 3 are arranged on one side of the main transmission line 1, and a characteristic test station 4, a mechanical break-in station 5, and a factory test station 6 are arranged on the other side. The factory test station 6 and the quick assembly station 2 are located at the two ends of the main transmission line 1, respectively. The main transmission line 1 is used to transport circuit breaker workpieces to be assembled and tested. A universal turntable is provided at the connection between each process station and the main transmission line 1. The universal turntable enables the circuit breaker workpieces to be transported between each process station and the main transmission line 1. The assembly line in this embodiment is designed by arranging the traditional assembly, debugging, and inspection processes according to a set process route, and integrating the process route with the assembly line and the testing and experimental tooling system. This realizes a process-based workflow mode for primary and secondary integrated pole-mounted circuit breakers, shortens the transition time, improves production efficiency, and provides a reliable guarantee for the rapid delivery of orders.
[0033] As an optional solution, in this embodiment, the main transmission line 1 includes a support frame 10 and rollers 11. At least two rows of rollers 11 are rotatably arranged on the support frame 10 perpendicular to the length direction of the main transmission line 1. Each row of rollers 11 is evenly distributed at equal intervals along the length direction of the main transmission line 1, which facilitates the movement of the circuit breaker workpiece on the rollers 11 by hand and reduces friction.
[0034] As an optional solution, in this embodiment, the support frame 10 is also provided with a foot pedal 12. The foot pedal 12 is located in the middle of each column of rollers 11. The width of the foot pedal 12 is greater than 30cm and less than the width of the circuit breaker workpiece, ensuring that both ends of the circuit breaker workpiece are on the rollers 11. Since the circuit breaker workpiece is large in size and weight, the foot pedal 12 can facilitate workers to get on the main transmission line 1 and push the circuit breaker workpiece to move on the rollers 11.
[0035] As an optional solution, in this embodiment, the height of the support frame 10 is 60cm-90cm; the axial length of each individual roller 11 in each row of rollers 11 is the same or different, preferably two rows of rollers 11 with different axial lengths are provided. By applying different thrusts to the circuit breaker workpiece, the rollers 11 at different positions will generate different rotation speeds, thereby enabling the circuit breaker workpiece to turn on the rollers 11, which is convenient and labor-saving; the rollers 11 are metal rollers, which are sturdy and durable.
[0036] As an optional solution, the process station in this embodiment includes a support 13, a worktable 14, and rollers 15. The bottom of the worktable 14 is connected to the support 13, so that the upper surface of the worktable 14 is flush with the upper surface of the main transmission line 1. A row of rollers 15 is arranged on both sides of the worktable 14. The rollers 15 are evenly distributed at equal intervals. The top of the rollers 15 is higher than the upper surface of the worktable 14, so that the circuit breaker workpiece can roll against the rollers 15. The axis of the rollers 15 is perpendicular to the length direction of the worktable 14. The distance between the two rows of rollers 15 is less than the width of the circuit breaker workpiece, so that the circuit breaker workpiece can be rolled on the two rows of rollers 15, which facilitates the movement of the circuit breaker workpiece.
[0037] As an optional solution, in this embodiment, the bracket 13 is an inverted U-shaped bracket, and each leg of the inverted U-shaped bracket is bolted to a foot cup 19 and a positioning bolt 20, which can be used to level the workbench 14. The positioning bolt 20 is connected to the lower end of the leg through a positioning plate. The positioning bolt 20 is used to connect to the bolt hole on the foundation to realize the positioning and fixation of the workbench 14 and prevent shaking during operation. The foot cup 19 can also be replaced with casters when it is necessary to move it.
[0038] As an optional solution, in this embodiment, the length direction of each workbench 14 is perpendicular to the length direction of the main transmission line 1; each workbench 14 is provided with at least one socket 16 on one side to facilitate the connection of assembly tools or the inspection of circuit breaker workpieces; the width of each workbench 14 is not less than the width of the circuit breaker workpiece; each workbench 14 is provided with a limit component, which includes a limit hole and a limit pin 17. The limit hole is provided on the upper surface of the workbench 14, and the limit pin 17 is inserted into the limit hole. The limit hole is at least 5 cm away from the end of the workbench 14, and the limit pin 17 is at least higher than the bottom surface of the transport plate of the circuit breaker workpiece to prevent the circuit breaker workpiece from moving out of the work position under the action of thrust; the middle of the workbench 14 is provided with a hollow to facilitate the operation space of the tools.
[0039] As an optional solution, in this embodiment, the characteristic test station 4 is equipped with a 360° flipping mechanism 24 and a circuit breaker characteristic test instrument. The 360° flipping mechanism 24 can be an electrically controlled rotary table with clamps, which can realize the 360° flipping of the circuit breaker workpiece, facilitating its testing and bottom assembly. The mechanical break-in station 5 is equipped with a circuit breaker final inspection tester, a programmable electrical break-in control device, and a mechanical break-in control device. There are two mechanical break-in stations 5, both located in a compartment 8. The workbench 14 extends into the compartment 8 through a workpiece opening. The factory test station 6 is equipped with a factory test instrument. The factory test station 6 is surrounded by a fence 9. A gantry crane 23 is installed above the main transmission line 1 inside the fence 9. The gantry crane 23 is used to transport qualified circuit breaker workpieces to the foundation or a transport vehicle.
[0040] As an optional solution, in this embodiment, a rework station 7 is set between the characteristic test station 4 and the mechanical break-in station 5 to facilitate the rework and placement of defective products, and to avoid the accumulation of circuit breaker workpieces on the main transmission line 1. Each process station is equipped with a movable stepping platform 18 in the foot area, which can be used to facilitate the assembly of different models of circuit breaker workpieces. If not needed, it can be moved to the warehouse, and if required, it can be used.
[0041] As an optional solution, in this embodiment, the universal turntable includes a support plate 21 and universal ball bearings 22. Universal ball bearings 22 are evenly distributed on the support plate 21. A foot pedal 12 is provided in the middle of the support plate 21. The foot pedal 12 is pre-set with anti-slip texture. The foot pedal 12 is 40cm long and 30cm wide, and can be used to support both feet to stand. Since the circuit breaker workpiece is large in size and weight, it is convenient for personnel to stand above the main transmission line 1 to push the circuit breaker workpiece to move and turn.
[0042] like Figure 5 As shown, the assembly process route in this embodiment generally includes three main parts: general assembly process A, debugging process B, and inspection and testing process C. General assembly process A includes a fast assembly station 2 and a slow assembly station 3. These stations are primarily responsible for six processes: assembling the arc-extinguishing chamber and poles of the circuit breaker component, assembling the spring mechanism, installing the transmission linkage, installing the current transformer, assembling the secondary wiring harness, and installing the bracket cover plate. Slow assembly station 3 has at least one more station than fast assembly station 2, allowing for better matching of production rhythm. Furthermore, slow assembly station 3 is located on one side of the main transmission line 1, facilitating wiring harness assembly (which is located on one side of the circuit breaker component). Debugging process B includes a characteristic test station 4, a rework station 7, and a mechanical break-in station 5, primarily responsible for three processes: characteristic testing, mechanical break-in, and rework repair of the circuit breaker component. Inspection and testing process C includes a factory test station 6, primarily responsible for factory tests of the circuit breaker component, such as loop resistance and power frequency withstand voltage. Among them, the characteristic test and mechanical break-in steps are both completed in the compartment 8 of the characteristic test station 4. The rework station 7 mainly receives unqualified products from the debugging process B, which generally involves specific steps in the above-mentioned general assembly process A. The unqualified semi-finished products can be returned to the corresponding station for rework according to which assembly step they are in, or they can be reworked and repaired at the rework station 7.
[0043] Example 2
[0044] This embodiment provides a primary and secondary integrated pole-mounted circuit breaker assembly line. Unlike Embodiment 1, it features four quick-assembly stations 2 and six slow-assembly stations 3. Both quick-assembly stations 2 and slow-assembly stations 3 are symmetrically arranged on both sides of the main transmission line 1. Characteristic testing station 4, rework station 7, mechanical break-in station 5, and factory testing station 6 are staggered on both sides of the main transmission line 1, which helps to shorten the total length of the main transmission line 1. The presence of more slow-assembly stations 3 than quick-assembly stations 2 allows for better matching of production cycles.
[0045] During production preparation, various pre-assembled circuit breaker mechanism box components, modular spring mechanisms, electronic voltage and current transformers, transmission linkage mechanisms, bracket covers, and other components are allocated according to the production plan at specific assembly stations. After production begins, the arc-extinguishing chamber, flexible connection, and other components are first assembled into the inner cavity of the solid-sealed pole. Following the process route, the modular spring mechanism is installed in the mechanism box sequentially using the assembly line, and the solid-sealed pole is also installed on the mechanism box. The output of the modular spring mechanism is connected to the moving conductive rod component of the solid-sealed pole using the transmission linkage mechanism. Then, the transformer is installed on the pole contact arm, completing the assembly of the circuit breaker. Based on this finished product, the secondary wiring of electrical components such as the circuit breaker opening and closing coils, energy storage motor, transformer, and auxiliary switches is carried out. After the wiring is completed, the mechanism box is sealed with a cover plate and enters the characteristic test station 4, compartment 8, for characteristic testing. Based on the characteristic test data results, the corresponding production work is carried out sequentially until the product is qualified and off the production line.
