Abstract
Provided is a technique for shortening a construction period and reducing manufacturing costs in a substation device which transforms supplied power and supplies the transformed power to equipment constituting a facility. Before the distribution board room 100 is installed, the cable tray 14, the power cables 15, and the cable length can be adjusted in advance. This reduces the number of operations for the installation site after installation of the distribution board room 100, and thus the construction period can be shortened. Further, by disposing the power cables 15 in the cable tray 14 before disposing the distribution board chamber 100, a place for temporarily disposing the power cables 15 during installation of the distribution board chamber 100 is not required. Therefore, an increase in unnecessary work such as temporary movement of the power cable 15 for securing the movement path of the distribution board chamber 100 can be prevented.

Detailed Description
Fig. 1 is a plan view showing a facility provided with a power transformation apparatus of the present invention. The facility shown in fig. 1 is, for example, a Liquefied Natural Gas (LNG) facility (hereinafter, simply referred to as "facility") that performs a process of liquefying Natural Gas as a fluid. The facility is provided with a large number of machines (process machines) for liquefying natural gas before or after liquefaction, and a pipe rack (pipe rack)3 provided in parallel with the process machines.
Since a large number of process machines are arranged in a facility, the description of each process machine is omitted in fig. 1 and 2, and the outline shape of the arrangement region (frame 2 described later) of the process machines is described. The pipe frame 3 is configured to hold a pipe through which a fluid transferred between the process machines of the housing 2 flows, in a configuration not shown in the drawings.
These process machines include power-consuming machines (power-consuming machines) driven by electric power such as pumps. The electric power for driving the process machine as the power consuming machine is supplied from, for example, a power generation facility not shown provided in the facility or an external power generation facility. The voltage of the power supplied from the power plant is higher (e.g. 69kV) than the voltage used in the process machine (e.g. 6.9kV or 400V). Therefore, in the facility, a substation (substation) 1 including a transformer for transforming high-voltage supply power into a voltage used in the process equipment and distributing the voltage to each process equipment is provided.
As shown in fig. 1, the facility of the present example is configured by arranging a large number of process machines provided in the facility in a manner divided into a plurality of housings 2, and one power transformation device 1 is provided for one or more housings 2. Fig. 2 is an enlarged plan view of the periphery of a part of the housing 2 (the range indicated by a chain line in fig. 1) in the facility shown in fig. 1. As schematically shown in fig. 2, the power transformation facility 1 and the process equipment in each enclosure 2 are connected by a power cable 15 routed through the arrangement area of the pipe frame 3, and the power transformed by the power transformation facility 1 is distributed to the process equipment in the enclosure 2. In fig. 2, reference numeral 9 denotes a cable for supplying electric power from the power generation facility to the facility. Further, although there may be several hundreds of power cables 15 provided between the substation equipment 1 and each enclosure 2, fig. 2 schematically shows a large number of power cables 15 in a summary manner. Therefore, the branching of the line representing the power cable 15 in fig. 2 does not necessarily mean that the branching is branched from one actual power cable 15 into a plurality of branches.
As shown in fig. 3, the power transformation apparatus 1 includes: a transformer 13 for transforming the supplied power; and a distribution board chamber 100 in which a plurality of distribution boards for supplying the transformed power to the respective process machines are housed. The power transformation equipment 1 includes a rack module 11 in which a plurality of cable racks 14 are arranged, and the plurality of cable racks 14 accommodate the plurality of power cables 15.
The distribution board chamber 100 is provided on the upper surface of a bridge portion 20 in a table shape having a plate-like body 21 provided on the upper surface of a frame including the leg portions 22, and is supported at a height position where a bridge module 11 described later can be disposed on the lower side of the distribution board chamber 100. The plate-like body 21 is formed in a rectangular planar shape, and the distribution board chamber 100 is disposed at the center in the longitudinal direction of the plate-like body 21. Further, when viewed along the longitudinal direction, the regions on the one end side and the other end side of the plate-like body 21 constitute the extension portions 12 which are provided so as to extend outward from the distribution board chamber 100. That is, the bridge portion 20 includes a pair of extending portions 12 that are provided so as to extend outward from the side surfaces of the distribution board chamber 100 that face each other. In fig. 3, reference numeral 23 denotes a connecting member which connects the side wall of the distribution board chamber 100 and the bridge portion 20 and suspends the end portion of the extension portion 12. The connecting member 23 may not be provided. Further, on the upper surface of each extension portion 12, for example, about 10 to 20 transformers 13 are provided. In fig. 3, 5, and 6, a cable for electrically connecting the transformer 13 to the switchboard is not shown.
Below the distribution board chamber 100 (more precisely, below the plate-like body 21), a bridge module 11 is provided. The rack module 11 is configured as a framework that supports cable racks 14, and a plurality of cable racks 14 are disposed in the rack module 11. The cable trays 14 are configured in a rectangular groove shape extending in the short side direction of the bridge portion 20, and when viewed in the long side direction of the bridge portion 20, a plurality of cable tray 14 groups arranged in the left and right direction are arranged in a plurality of shelf-like shapes in the vertical direction in the tray module 14. With this configuration, for example, tens of cable trays 14 can be disposed in each tray module 14. In order to avoid the drawings becoming complicated, only four cable trays 14 are shown in fig. 3 to 8 for simplicity.
Each cable tray 14 houses a power cable 15 for connecting each distribution board and a process machine. The power cables 15 are housed so as to extend in the longitudinal direction of the cable tray 14. A plurality of power cables 15 are housed in each cable tray 14, but in order to avoid the description becoming complicated, one power cable 15 is shown in the drawings.
Here, as shown in fig. 10, the transformer apparatus 101 installed in a facility has a structure in which: the distribution board chamber 100 is disposed on a support base 200 having a leg portion 202 on the lower surface, and the cable tray 14 is disposed below the distribution board chamber 100 (below the support base 200).
When a method of installing the substation equipment 101 in a facility site is described, for example, the distribution board room 100, the support table 200, and the cable tray 14 are integrally manufactured in a factory called a shop (shop). Subsequently, the manufactured power transformation equipment 101 is transported to a place where it is installed.
On the other hand, when the power transformation equipment 101 is transported to a place and further transported on the ground at the place, a jig 16 including wheels is disposed on the lower surface of the power transformation equipment 101, and the power transformation equipment 101 is moved while being placed on the jig 16 (fig. 9). At this time, the cable bridge 14 is temporarily detached from the lower surface of the support table 200 assembled in the workshop, and the above-described jig 16 is disposed at the position of the cable bridge 14. The jig 16 is, for example, a carriage (Self-Propelled Modular Transporters, SPMT) with a crane).
Then, the distribution board chamber 100 and the support base 200 are transported to the installation position as a unit by the jig 16, and the support base 200 is fixed to the installation place. Subsequently, after the jig 16 is retracted from below the support plate 201, the work of mounting the cable tray 14 again in the space where the jig 16 is disposed is performed. Further, the work of housing the power cables 15 in the cable trays 14 and the adjustment of the cable length of the power cables 15 are performed, and the power cables 15 are connected to the switchboard in the switchboard chamber 100 (fig. 10).
In the structure in which the jig 16 is used to carry out the ground transportation of the substation equipment 101 in this manner, there is a problem in that: since the installation of the cable tray 14 and the storage of the power cable 15 must be performed after the installation of the distribution board room 100, the work at the installation site becomes large.
Further, as described above, for example, the power cable 15 is routed through the arrangement region of the pipe frame 3. On the other hand, the racks 3 and the housings 2 are installed in parallel with the assembly of the substation equipment 101 on the plant side. Therefore, the power cable 15 is often installed together with the pipe frame 3 before the installation of the substation equipment 101, or a part of the power cable is buried in the ground.
In this case, a part of the large number of power cables 15, which have not been connected to the substation equipment 101, may be temporarily placed on the ground in a state of being wound in a coil shape. However, as described above, since the construction work of the facilities is being performed around the power cable, the power cable 15 placed temporarily may interfere with other construction work. In this case, a large number of power cables 15 that have been temporarily placed must be moved, and thus, an extra operation may be performed without directly assisting the construction of the facility.
The increase in work directly or indirectly related to installation of the substation equipment 1 described above may prevent a construction period of a facility from being shortened, or may cause problems such as an increase in labor cost associated with the increase in work. These problems become particularly acute in developed countries where the salary of field workers is high or where it is difficult to secure labor.
To solve these problems, in the power transformation equipment 1 of the present embodiment including the configuration described with reference to fig. 3, the bridge module 11 in which the cable bridge 14 is disposed and the main body module 10 in which the distribution board chamber 100 and the transformer 13 are provided in the bridge portion 20 are manufactured separately.
For example, the bridge module 11 is manufactured prior to the body module 10 and is transported to a place where the bridge module is installed. As shown in fig. 4, the bridge module 11 is first installed in the installation site of the substation equipment 1. By placing the bridge module 11 in advance, the work of accommodating the power cable 15 in the cable bridge 14 and adjusting the cable length can be performed. In addition, a symbol 115 shown in fig. 4 is a cable trench (cable trench) for burying the power cable 15 underground.
After the power cables 15 are stored in the cable tray 14 in advance, the main body module 10 is transported to a facility installation site. In the main body module 10 of this example, a jig 16 is disposed on the lower surface side of a pair of extension portions 12 extending from the right and left sides of the lower surface of the distribution board chamber 100. The lower surface of the extension 12 is supported by the jig 16, and thus a space into which the rack module 11 can be inserted is formed below the distribution board chamber 100.
The main body module 10 is moved so that the previously installed bridge module 11 is disposed below the distribution board chamber 100 (fig. 5). Subsequently, the jig 16 is removed and retreated from the lower side of the extension portion 12, and the bridge portion 20 is fixed to a place. Thus, a distribution board chamber 100 can be disposed above the cable tray 14 (tray module 11), and the distribution board chamber 100 houses a distribution board for distributing power to the process equipment. Then, the distribution board is connected to the plurality of power cables 15 housed in the rack module 11 in advance (fig. 6). Thereby, the installation (manufacturing) of the power transformation apparatus 1 is completed.
Before the distribution board room 100 is installed by the above-described configuration, the installation of the cable tray 14, the storage of the power cables 15, and the adjustment of the cable length can be performed in advance. This reduces the number of operations for the installation site after installation of the distribution board room 100, and thus the construction period can be shortened. Further, by disposing the power cables 15 in the cable tray 14 before disposing the distribution board chamber 100, the power cables 15 do not need to be temporarily disposed until the distribution board chamber 100 is installed. Therefore, it is possible to prevent the occurrence of unnecessary work such as the movement of the temporarily placed power cable 15 accompanying the progress of the construction work of the facility. The leg 22 may be detachable from the main body module 10. Further, the following structure may be adopted: the leg 22 is placed in a place prior to the body module 10 together with the bridge module 11, and then a portion upward from the plate-like body 21 of the body module 10 is placed above the leg 22.
Further, as shown in fig. 6, according to the configuration in which the transformer 13 is disposed on the extension portion 12 provided so as to extend to the outside from the distribution board chamber 100, the transformer 13 and the distribution board chamber 100 can be manufactured as the integrated body module 10 and transported to the installation place. Therefore, the work of installing the transformer 13 on site is not required. For example, when the transformer 13 is installed on the ground, a dedicated area for installing the transformer 13 must be secured, but by disposing the transformer 13 on the upper surface of the extension portion 12, the lower area of the transformer 13 can be used for other purposes. As another use example, an installation area of the cable trench 115 for guiding the power cable 15 underground is exemplified.
Further, it is not essential to provide the bridge portion 20 including the support plate 201 with the extension portion 12 on the lower surface of the distribution board chamber 100. As in the substation equipment according to the other embodiment shown in fig. 7, the rack module 11 and the cable rack 14 may be installed, the power cables 15 may be arranged in the cable rack 14, and then the distribution board room 100 may be placed on the rack module 11 by a crane (crane) or the like. In this configuration, since the cable tray 14 and the power cables 15 can be installed and stored before the distribution board room 100 is installed, the same effect as that of the substation equipment 1 according to the embodiment described with reference to fig. 3 to 5 can be obtained.
As another example, instead of providing the cable trays 14 in the tray module 11 configured by integrating a plurality of cable trays 14 and a frame for supporting them, a method of individually providing the cable trays 14 in a place may be employed. For example, as shown in fig. 8, before the distribution board chamber 10 is installed, a plurality of support portions 111 are disposed at intervals corresponding to the longitudinal direction of the cable tray 14, and the plurality of support portions 111 include a vertically extending pillar and a plurality of beams provided so as to extend horizontally from different height positions of the pillar. The cable tray 14 is supported by the beams of the support portion 111, and the power cables 15 are housed in the cable trays 14. In this configuration, since the cable tray 14 and the power cable 15 can be installed and housed before the distribution board room 10 is installed, the same effect as that of the substation equipment 1 according to each of the embodiments described above can be obtained.
The power transformation equipment 1 and the method for manufacturing the same according to each embodiment described above are not limited to the case of being applied to an LNG facility that liquefies natural gas. The present invention is applicable to various facilities such as a natural gas facility for separating and recovering natural gas and liquid, a petroleum refining facility for distilling and desulfurizing crude oil and various intermediate products, and a chemical facility for producing petrochemicals, intermediate chemicals, polymers, and the like, and to a power transformation facility 1 for distributing electric power to various devices provided in these facilities.
