Description

Technical Field

[0001] This invention belongs to the field of transformer technology, and particularly relates to a movable base transformer that facilitates the installation of low-voltage switchgear. Background Technology

[0002] In the manufacturing process of Eurotransformer, the installation of low-voltage switchgear is one of the key steps that determines the product production cycle. As the core component of Eurotransformer responsible for power distribution, control and protection, the low-voltage switchgear is large in size and heavy in weight, with a single unit typically weighing several hundred kilograms. During installation, lifting equipment such as gantry cranes is required for positioning and transportation.

[0003] However, most of the European-style enclosures currently on the market adopt a fully welded structure design: the side panels, fixed brackets, door frames and other components of the enclosure are all connected to the base and top plate by welding, and the positions of all parts are fixed and cannot be adjusted. This structure exposes numerous problems during low-voltage switchgear installation: Limited operating space: Fixed supports and door frames create spatial obstacles, preventing the gantry crane from directly moving the low-voltage switchgear to the preset installation position, requiring multiple fine-tuning adjustments to the angle and height; High repetitive workload: Due to non-removable parts, workers must repeatedly operate the gantry crane to adjust the position, often requiring 3-5 adjustments per installation to achieve precise positioning, extending the installation time of a single unit and increasing worker fatigue; Low production efficiency: Taking a standard capacity European-style transformer as an example, the installation time for a single unit's low-voltage switchgear under the traditional structure is approximately 2-3 hours, with waiting and operation time due to position adjustments accounting for over 40%, severely restricting the factory's mass production speed; Increased safety risks: During multiple adjustments, the low-voltage switchgear is in a suspended or semi-suspended state. Improper operation or positioning deviation of the lifting equipment may cause the low-voltage switchgear to collide with the outer casing, resulting in equipment damage or safety accidents. As the power industry's requirements for equipment delivery cycles continue to increase, the structural defects of traditional European-style transformer casings have become a key factor hindering the improvement of industry production efficiency. Designing a transformer enclosure that can guarantee both protective performance and structural stability while enabling rapid installation of low-voltage switchgear has become a critical technological bottleneck that the transformer manufacturing industry urgently needs to overcome. Summary of the Invention

[0004] The purpose of this invention is to overcome the problems of cumbersome installation steps and long production cycles of existing low-voltage switchgear due to the all-welded structure of the casing, and to provide a movable base-mounted low-voltage switchgear with a reasonable structure and convenient operation. This reduces the number of adjustments required for the gantry frame during low-voltage switchgear installation, decreasing the number of adjustments per installation from the traditional 3-5 times to 1 time, significantly shortening installation time; it simplifies the low-voltage switchgear installation process, reduces the operational difficulty and repetitive workload for workers, and improves the production efficiency of a single unit; while ensuring the overall rigidity and protective performance of the casing, the design of movable components provides ample operating space for low-voltage switchgear installation; and it shortens the overall production cycle of the low-voltage switchgear and reduces factory production costs.

After the controller calculates the deviation, it starts the horizontal and / or vertical adjustment slider for fine adjustment. After alignment, the locking mechanism closes instantly to fix the low-voltage switchgear.

[0012] Optionally, the preset spacing is 1-5cm.

The baffle (11) can ensure that the movable low-voltage cabinet base (10) does not tilt when it moves.

Push the movable low-voltage cabinet base (10) back into the cabinet body. Turn the low-voltage cabinet base fixing buckle (3) to fix the movable low-voltage cabinet base (10) to the European transformer base (2). Since the low-voltage cabinet can be fixed to the movable low-voltage cabinet base (10) by adjusting the gantry once, compared with the conventional cabinet structure that requires multiple adjustments of the gantry position, the European transformer with this structure is more convenient to install and can greatly shorten the installation time. Includes: the side panels (8) are fixed together by welding, the transformer base (2) is fixed to the side panels (8) by welding, the right door (6) and the left door with markings (7) are connected to the side panels (8) by bolts to achieve the function of closing, the movable low-voltage cabinet base (10) and the side of the transformer base (2) are in contact by rollers (4) to greatly reduce friction force, so that the movable low-voltage cabinet base (10) can be freely pulled out and pushed back into the transformer cabinet, the detachable door frame (5) is fixed to the side panels (8) by screws, and is not directly welded to the side panels (8), and the top plate (1) is fixed to the crossbeam (5) by its own weight; since the low-voltage cabinet can be directly fixed to the movable low-voltage cabinet base (10) outside the cabinet when it is installed, it is not necessary to adjust to the gantry position multiple times, which simplifies the installation steps and greatly shortens the installation time of the transformer.

[0022] This invention can greatly improve the efficiency of installing low-voltage switchgear, shorten the production cycle of transformers, and improve factory efficiency.

[0023] This invention provides a movable base-type transformer housing structure for easy installation of low-voltage switchgear, which completely solves the above-mentioned problems through innovative design. The structure consists of a top plate (1), a transformer base (2), a low-voltage switchgear base fixing buckle (3), a roller (4), a crossbeam (5), a right side door (6), a left side door with markings (7), a side panel (8), low-voltage switchgear fixing screw holes (9), a movable low-voltage switchgear base (10), and a baffle (11). The top plate (1) is made of 2mm thick galvanized steel plate and is connected to the crossbeam (5) by gravity fitting to avoid welding deformation; the base (2) is an integral welded frame that forms a rigid support with the side plate (8) and is coated with an anti-rust coating; the low-voltage cabinet base fixing buckle (3) is located behind the right door (6) and the left door with marking (7), and is quickly locked by spring steel sheet and can withstand shear force of more than 500kg; the roller (4) is made of stainless steel with hard chrome plating, and has a friction coefficient ≤0.15. Each group contains 2 rollers and 4 groups are evenly distributed; the crossbeam (5) is a hollow structure design to reduce the overall weight; the right door (6) and the left door with marking (7) are connected to the side plate (8) by bolts to achieve It has an on / off function; the side panels (8) are fixed by welding, and the outer side is reinforced with ribs to improve the impact resistance; the low-voltage cabinet fixing screw holes (9) are distributed on the surface of the movable low-voltage cabinet base (10), and the spacing is customized according to the standard low-voltage cabinet size (e.g., 800mm×600mm), with a hole tolerance of ±0.5mm; the main body of the movable low-voltage cabinet base (10) is a square tube welded structure, with rollers (4) integrated at the bottom, supporting pull-out movement; the baffle (11) is located at the front end of the base, using L-shaped bent steel plate, and is fixed by bolts to prevent tilting, with a height of 1 / 3-1 / 2 of the base height; the detachable door frame (5) is connected to the side panel (8) by self-tapping screws with a screw spacing of 200mm, supporting quick disassembly and assembly.

[0024] The installation process consists of five steps: First, the worker pulls the movable low-voltage switch base (10), the roller (4) slides on the guide rail of the transformer base (2), and the baffle (11) restricts the range of movement to ensure that the base remains horizontal; Second, the gantry hoist the low-voltage switch to the top of the base, and the worker uses visual inspection or a laser positioning instrument to align the positioning hole at the bottom of the low-voltage switch with the fixing screw hole (9); Third, use M12 high-strength bolts to pass through the screw hole and tighten them with anti-loosening nuts, with the torque controlled at 50-60 N·m; Fourth, push the base back into the cabinet and pry open the low-voltage switch base fixing buckle (3) to lock the position; Finally, connect the detachable door frame (5) to the side plate (8) with self-tapping screws, and adjust the number of screws according to the size of the door frame (usually 4-6). This structure, with its movable base design, enables rapid installation of low-voltage cabinets while ensuring the rigidity and protective performance of the outer shell. The operating space is increased by 40% compared to traditional structures, the installation time per unit is reduced from 2.5 hours to 1.2 hours, the number of adjustments is reduced by 80%, the stability of base movement is improved by 60%, the risk of suspended adjustment is avoided, the detachable door frame supports quick disassembly and assembly, and the maintenance time per operation is reduced from 30 minutes to 8 minutes.

[0025] The roller (4) system is made of stainless steel with hard chrome plating. The friction coefficient is ≤0.15, and the service life is extended by 3 times. Each base contains 4 sets of rollers, each with 2 rollers, which are evenly distributed to disperse the load. A guide rail (12) is added to the inside of the base (2) of the variable transformer. It is made of aluminum alloy profile with surface oxidation treatment and the movement accuracy reaches ±1mm. The baffle (11) is fixed to the edge of the base by bolts through an L-shaped bent steel plate to form a three-point support. It contacts the ground when pulled out to prevent the base from tilting. A spring buffer device is added to reduce the impact force of pulling out by 50%. The spacing of the screw holes (9) of the low-voltage cabinet is customized according to the standard low-voltage cabinet size. The hole tolerance is ±0.5mm. The screw hole surface is coated with an anti-loosening coating to prevent the screws from falling off. A laser positioning mark is added to improve the alignment efficiency. The detachable door frame (5) is connected to the side panel (8) by self-tapping screws with a screw spacing of 200mm. It is equipped with a quick-release handle, which allows a single person to complete the disassembly and assembly within 5 minutes. A rubber sealing strip is added to the edge of the door frame to prevent rainwater from seeping in. The top panel (1) is fitted and fixed to the crossbeam (5) by its own weight, without the need for additional fasteners. A waterproof groove is added to the edge of the top panel to prevent rainwater from accumulating. The crossbeam adopts a hollow structure to reduce weight and improve wind resistance.

[0026] In implementation cases, after small and medium-sized European-style transformers (capacity ≤ 500kVA) were applied in space-constrained assembly workshops, the installation time per unit was shortened to 1.2 hours, and production efficiency was increased by 40%. A manufacturing plant's monthly output increased from 50 units to 80 units, and the rework rate was reduced by 30%. After large European-style transformers (capacity > 500kVA) were applied in projects with high precision requirements (such as data center power supply systems), the guide rails ensured that the base positioning error was ≤ 2mm, which is better than the ±5mm of traditional structures. The installation accuracy of a new energy power station project was improved by 60%, and the accident rate was reduced by 50%. After smart integration projects were applied in high-end projects requiring automation and data monitoring, sensors monitored the base status in real time, and the automation rate of the installation process was increased to 70%. The data traceability system of a smart grid project increased the quality pass rate to 99%. The technological advantages are reflected in four aspects: improved efficiency, enhanced safety, optimized costs, and industry impact. Installation time per unit is reduced from 2-3 hours to 1-1.5 hours, the number of adjustments is reduced by 80%, and mass production speed is increased by 30%-50%, meeting the stringent delivery cycle requirements of the power industry. The number of suspended adjustment steps is reduced by 90%, significantly lowering the accident rate; the coordinated design of the baffle and rollers improves the stability of base movement by 60%. Annual maintenance costs are reduced by 20%-30%, roller lifespan is extended by 3 times, and modular design reduces single maintenance time from 30 minutes to 8 minutes. This technology drives the transformation of Eurotransformer's manufacturing industry from traditional welding to modular and intelligent systems, providing reliable solutions for high-end projects such as new energy power plants and data centers. Through structural innovation and detailed optimization, this invention provides Eurotransformer's manufacturing industry with an efficient, safe, and economical solution, demonstrating significant technological advancement and market competitiveness.

[0027] Example 2 This embodiment uses an automatic fixing mechanism for low-voltage cabinets.

[0028] In the movable base structure of the European transformer casing, the introduction of an automatic fixing mechanism can completely eliminate the need for manual intervention, further improving the quality, efficiency and convenience of low-voltage switchgear installation. The core of this extended solution is to automate the traditional manual alignment and bolt fixing process, and to achieve precise and rapid locking of the low-voltage switchgear and the base through a mechanical device. The specific solution is as follows: The movable low-voltage switchgear base (10) integrates an automatic fixing system consisting of sensors, drive mechanisms and locking components. When the gantry hoists the low-voltage switchgear above the base, the laser positioning sensors (200mm spacing) on ​​the edge of the base detect the position of the positioning holes at the bottom of the low-voltage switchgear in real time and feed the data back to the built-in controller. The controller calculates the deviation according to the preset program, starts the micro stepper motor to drive the horizontal and / or vertical adjustment sliders, so that the low-voltage switchgear is automatically fine-tuned to be completely aligned with the fixing screw holes (9). After alignment, the electromagnetically driven locking mechanism (each group contains 4 spring steel clips) closes instantly, and the low-voltage switchgear is fixed by a rapid locking mechanism with a shear force of 500kg. The whole process does not require manual operation. A visual assistance system (such as LED indicator lights) added to the front of the base provides real-time feedback on the alignment status, ensuring transparent operation. The advantages of this mechanical device are: firstly, significantly improved installation quality, with screw hole alignment accuracy reaching ±0.1mm, far superior to the ±1mm tolerance of manual operation, reducing equipment vibration caused by misalignment; secondly, installation time is reduced from the original 1.2 hours to within 10 minutes, with 80% fewer adjustments and a 60% increase in mass production speed; thirdly, enhanced safety, eliminating the suspension adjustment step, reducing accidents or equipment damage caused by broken suspension ropes, etc., resulting in a 90% reduction in the accident rate. In a case study, a manufacturer, after applying this to European-style transformers below 500kVA, saw a 40% increase in single-unit installation efficiency, a 35% decrease in rework rate, and a 25% reduction in annual maintenance costs. In terms of technical details, the roller (4) system has been upgraded to a ceramic-coated roller with a low coefficient of friction (≤0.1), extending its lifespan by 5 times; the baffle (11) integrates a pressure sensor to automatically detect the horizontal status of the base; the detachable door frame (5) supports single-person disassembly and assembly in 3 minutes via quick-release screws (150mm spacing). This solution promotes the intelligent transformation of Eurotransformation's manufacturing industry, and is especially suitable for space-constrained assembly workshops or projects with high precision requirements, such as data center power supply systems.

[0029] Example 3 This embodiment employs a robot-automated docking track installation system.

[0030] To address the complexity of manual assembly of low-voltage switchgear in European transformer systems, a robotic automatic docking track installation system integrates industrial robots and intelligent tracks to achieve fully automated and precise positioning and installation of the low-voltage switchgear. The core of this extended solution is to use robots to replace gantry cranes and manual operations, completing the entire process from handling to fixing. The specific solution is as follows: An aluminum alloy guide track (12) is added to the inner side of the European transformer base (2), with surface oxidation treatment, achieving a movement accuracy of ±0.5mm. An RFID tag is integrated at the end of the track for robot positioning and identification. A magnetic coupler is installed at the bottom of the movable low-voltage switchgear base (10) to seamlessly dock with the track. During installation, a six-axis industrial robot (load capacity ≥800kg) identifies the position of the low-voltage switchgear through a vision system, grabs it, and slides it along the track to the preset installation point. A laser rangefinder monitors the distance between the base and the cabinet in real time, with the error controlled within ±0.1mm. The robot's built-in torque sensor automatically adjusts the gripping force to avoid equipment damage. After the low-voltage cabinet is in place, the pneumatic locking device on the base closes instantly, fixing the cabinet with a shearing force of 500kg. No manual intervention is required throughout the process, which takes only 15 minutes. The advantages of this system are: firstly, the installation accuracy is improved to ±0.1mm, which is better than the ±5mm of the traditional structure, meeting the needs of high-end projects such as new energy power plants; secondly, the installation time is shortened from 2.5 hours to 15 minutes, and the production efficiency is improved by 80%; thirdly, safety is maximized, eliminating the risk of suspended operation and reducing the accident rate by 95%. In the implementation case, after the application of this system in a smart grid project, the automation rate of the installation process reached 70%, the quality pass rate was improved to 99%, and the annual maintenance cost was reduced by 30%. In terms of technical details, the roller (4) system is upgraded to a self-lubricating bearing with a friction coefficient ≤0.08; the baffle (11) integrates a pressure feedback module for automatic correction; the detachable door frame (5) can be disassembled and assembled in 2 minutes using an electric screwdriver (100mm spacing). This solution promotes the transformation of the transformer manufacturing industry towards unmanned production, and is especially suitable for large transformers (capacity > 500kVA) or scenarios with high precision requirements, such as data center power supply systems, significantly enhancing the industry's competitiveness.
