Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial plant engineering design technology, specifically to an empty shell plant that is easy to modify power distribution lines. Background Technology
[0002] For industrial production, the power distribution room is an indispensable infrastructure. It is responsible for converting high-voltage electrical energy into low-voltage electrical energy to provide power to various electrical equipment. When constructing an industrial plant, a general-purpose empty shell plant is usually built first. Then, the manufacturer moves the production equipment into the plant, and the power distribution lines are arranged according to the specific production line locations and needs.
[0003] Existing shell factory buildings are constructed without considering future expansion. Typically, only a main power distribution room is set up on the first floor, with each floor either not connected or connected by electrical shafts. When the initial production scale is small and there are few production lines, the power distribution room on the first floor can meet the needs. However, when the production scale expands and more production lines need to be added, especially when adding production lines on the upper floors of the factory, the factory's power distribution lines need to be extensively modified. In this case, a new power distribution room must be built on the upper floor, and the power distribution lines must be rebuilt. Sometimes the location of the power distribution room is far from the electrical shafts, and sometimes the factory does not have electrical shafts. In this case, it is necessary to break through the walls or floors and ceilings of the building to introduce the cables. The project is large in scale, time-consuming and labor-intensive, and the entire factory must be shut down for a long time while waiting for the modification to be completed, which greatly affects production efficiency. Summary of the Invention
[0004] To address the drawbacks of existing empty factory buildings, such as large workload, time and labor costs, and the need for prolonged power outages and production stoppages while waiting for the renovation to be completed, which affects production efficiency, this utility model provides an empty factory building that facilitates the modification of power distribution lines. The modification of power distribution lines is convenient and quick, and does not affect production efficiency.
[0005] A shell factory building that facilitates the modification of power distribution lines includes a multi-story factory building, characterized in that: each floor of the multi-story factory building is equipped with a power distribution room, and each power distribution room on each floor is equipped with an electrical shaft, the electrical shaft connecting all the power distribution rooms vertically, the power distribution room is divided into a main power distribution room and floor-level power distribution rooms, the main power distribution room is equipped with a transformer and a distribution cabinet, and the floor-level power distribution rooms are equipped with busbar trunking and plug-in boxes, the busbar trunking and the plug-in boxes being connected to the transformer in the main power distribution room via cables and electrical shafts.
[0006] Its further features are:
[0007] The distribution cabinet includes a first-phase distribution cabinet and a second-phase distribution cabinet. The first-phase distribution cabinet is connected to the transformer, and the second-phase distribution cabinet is connected to the first-phase distribution cabinet via a bus bridge.
[0008] The main power distribution room is provided with spare space that is at least larger than the space required to install two sets of the transformers and the power distribution cabinet;
[0009] There are two transformers, and the total capacity of the two transformers is less than 5000 kVA;
[0010] Each of the layered power distribution rooms contains at least two plug-in boxes, and each plug-in box in a layered power distribution room is connected to a different voltage segment of the transformer.
[0011] With the above-described structure of this utility model, power distribution rooms are pre-arranged on each floor of the empty factory building. Each floor's power distribution room is connected vertically via electrical shafts. If a production line needs to be added to an upper floor later, no large-scale modifications are required; the new power distribution cabinet can simply be moved into the power distribution room and connected to the plug-in box. The modification process is convenient and quick. If the capacity of the newly added transformer is insufficient, the bus bridge between the first-phase and second-phase power distribution cabinets can be disconnected, and the second-phase power distribution cabinet can be connected to the new transformer, thus converting it into two power distribution units. During the modification process, the first-phase and existing power distribution cabinets can continue to operate, and the factory power lines do not need to be disconnected, thus not affecting production efficiency. The main power distribution room has at least more space than required to install two sets of transformers and power distribution cabinets, eliminating the need to expand the power distribution room or move the original power distribution units, further ensuring the convenience and speed of the modification process. Each floor's power distribution room has at least two plug-in boxes, each connected to a different voltage segment of the transformer, meeting different needs for later modifications and further improving the convenience and speed of the modification process. The main power distribution room has ample space, at least larger than the space required to install two sets of transformers and distribution cabinets, providing room for major renovations and making the renovations more convenient and efficient.

[0013] Figure 2 This is a structural diagram of a multi-level power distribution room;
[0014] Figure 3 This is a schematic diagram of the main power distribution room. Detailed Implementation
[0015] See Figure 1 A type of shell factory building that facilitates the modification of power distribution lines includes a multi-story factory building 12, with a power distribution room on each floor. The number of floors and the number of power distribution rooms on each floor are determined by specific needs. Figure 1 The building has five floors, with one power distribution room on each floor. Each power distribution room is equipped with an electrical shaft 3, which connects all the power distribution rooms vertically. The electrical shaft 3 does not occupy the space outside the power distribution rooms, thus saving factory space.
[0016] The power distribution room is divided into a main power distribution room 1 and a floor-level power distribution room 2. The main power distribution room 1 is usually located on the first floor or the basement floor, while the power distribution rooms on the other floors are all floor-level power distribution rooms 2.
[0017] See Figure 2 , Figure 3 The main distribution room 1 contains a transformer 6 and a distribution cabinet. The sub-distribution rooms 2 contain busbar trunking 4 and plug-in boxes 5. The busbar trunking 4 and plug-in boxes 5 are connected to the transformer 6 in the main distribution room 1 via cables and electrical shafts 3. Each sub-distribution room 2 contains at least two plug-in boxes 5. Figure 1 There are three in the middle, and each plug box 5 in a layered power distribution room 2 is connected to a transformer 6 for different voltage segments.
[0018] The distribution cabinet includes a first-phase distribution cabinet 7 and a second-phase distribution cabinet 8. The first-phase distribution cabinet 7 is connected to the transformer 6, and the second-phase distribution cabinet 8 is connected to the first-phase distribution cabinet 7 through a bus bridge 9.
[0019] The main power distribution room 1 has a spare space 11 that is at least larger than the space required to install two sets of transformers and distribution cabinets, which reserves space for major changes and renovations.
[0020] There are two transformers (6), and the total capacity of the two transformers is less than 5000 kVA. According to national regulations, transformers with a capacity of less than 5000 kVA do not require application, and construction can start quickly in the early stages. Applications can be submitted later when capacity expansion is needed.
[0021] When making renovations later, when adding production lines on the upper floors, the new power distribution cabinet can be moved into the floor distribution room 2 and connected to the plug box 5. There is no need to chisel through the walls, floors or ceilings of the multi-story factory building, making the renovation process convenient and quick.
[0022] When the capacity of transformer 6 is insufficient, a new transformer 10 is moved into the main power distribution room 1, the bus bridge 9 between the first-phase power distribution cabinet 7 and the second-phase power distribution cabinet 8 is disconnected, and the second-phase power distribution cabinet 8 is connected to the new transformer 6, which can be transformed into two power distribution units. During the transformation process, the first-phase power distribution cabinet 7 and the original power distribution cabinet can continue to work, the power supply of the factory does not need to be interrupted, and the production efficiency is not affected.
