First Embodiment
FIG. 1 is a diagram showing an example of a manufacturing support system 1 including an installation support device 100 for the gas-insulated switchgear 10 of the first embodiment. For example, the manufacturing support system 1 includes a plurality (two or more) of GIS units UT constituting one gas-insulated switchgear (hereinafter, GIS (Gas-Insulated Switchgear)) 10, a 3D scanner 50, and an installation support device of the GIS 10. 100 and the terminal device 200.

  The GIS 10 is a circuit breaker that opens and closes current in an insulating gas, and is installed, for example, in an installation target facility such as a substation or a power plant. The GIS 10 is manufactured by combining a plurality of GIS units UT. The GIS unit UT is composed of two or more devices (parts) such as current transformers and disconnectors. For example, the GIS unit UT has a size that can be transported from the factory to the installation facility as one unit. The transportable size may be, for example, a size that can be loaded on the transport trailer to the maximum, or may be the maximum size defined by a law or regulations. Further, the GIS unit UT may be, for example, a unit divided by a predetermined device (for example, a bellows or the like described later) when assembled as the GIS 10.

  The configuration of the GIS 10 will be described below with reference to FIGS. 2 to 4. FIG. 2 is a single-wire connection diagram showing an example of the configuration of the GIS 10. FIG. 3 is a diagram showing an example of the configuration of the GIS 10 as viewed from above. FIG. 4 is a diagram showing an example of the configuration of the GIS 10 as viewed from the side. In the figure, z represents the vertical direction, x represents one direction of the horizontal plane orthogonal to the vertical direction z, y is the other direction of the horizontal plane orthogonal to the vertical direction z, and orthogonal to the x direction It represents the direction.

For example, the GIS 10 includes the circuit breaker 11, the instrument current transformers 12a and 12b, the disconnectors 13a, 13b and 13c, the working earthing switches 14a and 14b, the line side earthing switch 14c, and the bushing 15 , Instrument transformer 16, arrester 17, integrated busbar disconnectors 20a and 20b, attaching / detaching devices 21a and 21b, gas-insulated busbar 25, disconnector earthing switch 26, branch bus 27 and T And a pedestal BW and a pedestal PD. Tubular gas insulation in which insulating gas such as SF ₆ (sulfur hexafluoride) gas having excellent insulation property is enclosed in part or all of the plurality of devices or the path (pipes etc.) connecting the devices It is housed in a container.

One circuit breaker 11 is provided for each of the three phases. Each breaker 11 is connected between the instrumental current transformers 12a and 12b, and switches to a conducting state or an open state. For example, the circuit breaker 11 may have a configuration in which a contact portion for opening and closing an electrical path is accommodated inside a cylindrical gas insulating container in which an insulating gas such as SF ₆ (sulfur hexafluoride) gas is enclosed. .

Instrumental current transformer 12a includes a bus integrated type disconnector 20a incorporating the first main bus LN1 and a second main bus LN2 incorporating the first main bus LN1 via the disconnecting switches 13a and 13b and the working earthing switch 14a. It is connected to the disconnector 20b. The first main bus LN1 and the second main bus LN2 are obtained by collectively assembling the busses of the three-phase circuit. In the busbar integrated disconnector 20a and the busbar integrated disconnector 20b, an insulating gas such as SF ₆ (sulfur hexafluoride) gas is enclosed in a cylindrical gas insulating container. The first main bus LN1 and the second main bus LN2 are arranged, for example, to be parallel to each other at substantially the same height.

  The instrumental current transformer 12b is connected to the bushing 15 via the working earthing switch 14b, the disconnector 13c, and the line-side earthing switch 14c. An instrument transformer 16 and a lightning arrester 17 are connected between the line-side ground switch 14 c and the bushing 5.

  The instrumental current transformers 12a and 12b convert the magnitude of the alternating current flowing in the circuit. Disconnectors 13a, 13b, and 13c and bus-bar integrated disconnectors 20a and 20b open and close the circuit when no current flows in the circuit (in the absence of current). The working earthing switches 14a and 14b and the line-side earthing switch 14c ground the circuit for safety in checking the equipment such as the circuit breaker. The bushing 15 is, for example, a cylindrical ladder that connects electric wires from a steel tower that suspends a power transmission line and connects the electric wires to the circuit of the GIS 10. The instrument transformer 16 converts the magnitude of the AC voltage flowing in the circuit. The lightning arrester 17 protects other devices connected downstream from a transient high voltage such as lightning.

A bellows BW is connected between the busbar integrated disconnector 20a and the busbar integrated disconnector 20b. The bellows BW is a pipe (pipe joint) having a bellows structure and having elasticity and bending. The bellows BW may also be connected between the bushing 15 and the gas insulated bus 25. The gas-insulated bus 25 is obtained by collecting the busses of the three-phase circuit at one time, like the first main bus LN1 and the second main bus LN2. In the gas-insulated bus bar 25, an insulating gas such as SF ₆ (sulfur hexafluoride) gas is enclosed in a tubular gas-insulated container, and a three-phase collective bus extending in the axial direction is used. Be housed.

  The gantry PD is made of, for example, a metal member having a plurality of legs. The bottoms of the legs of the gantry PD are welded to a metal base which is previously embedded in the foundation (for example, a concrete foundation) of the installation facility. The GIS 10 is installed at a facility to be installed by being fixed on a gantry PD fixed to a foundation.

  The GIS unit UT described above includes, for example, a plurality of devices such as the circuit breaker 11, the instrument current transformers 12a and 12b, the disconnectors 13a and 13b, the instrument transformer 16, and the bus bar integrated disconnectors 20a and 20b. It is good as a unit. The GIS unit UT may include other devices in addition to or instead of these various devices.

  The 3D scanner 50 is connected to the installation support device 100 by wire or wirelessly. The 3D scanner 50 irradiates, for example, a laser beam to an object, and three-dimensional shape data of the object based on the phase shift between the reflected light reflected by the object and the reference light of the light source Hereinafter, three-dimensional shape data is generated. In the present embodiment, the object of the 3D scan is the GIS unit UT. In addition, the 3D scanner 50 may generate three-dimensional shape data of the object by, for example, irradiating a laser beam in the form of a dot pattern. Then, the 3D scanner 50 outputs the generated three-dimensional shape data to the installation support device 100.

  The terminal device 70 is, for example, a computer device such as a mobile phone such as a smartphone, a tablet terminal, or a personal computer. The terminal device 70 may be used by, for example, a manufacturer of the GIS 10, an installation worker who installs the GIS 10 in a facility to be installed, or a maintenance worker who performs maintenance of the GIS 10.

  The installation support device 100 of the GIS 10 uses the three-dimensional computer graphics (3DCG) based on the three-dimensional shape data output by the 3D scanner 50 to generate three of the overall configuration images when the GIS 10 is virtually assembled. Generate dimensional shape data. Then, the installation support device 100 causes the screen of the terminal device 70 to display a virtual overall configuration image of the GIS 10 by outputting the generated three-dimensional shape data to the terminal device 70 or the like.

  FIG. 5 is a diagram showing an example of the configuration of the installation support device 100 of the GIS 10. As shown in FIG. For example, the installation support device 100 includes a communication unit 102, a display unit 104, an operation unit 106, a control unit 110, and a storage unit 130. The display unit 104 is an example of the “output unit”. When information is output to the terminal device 70 via the communication unit 102, the communication unit 102 is another example of the “output unit”.

  The communication unit 102 includes a hardware interface such as a NIC (Network Interface Card) connectable to the network NW, and a hardware interface such as a USB. The network NW includes, for example, a local area network (LAN), a wide area network (WAN), a wireless base station, a Wi-Fi access point, and the like. For example, the communication unit 102 communicates with the 3D scanner 50 via the network NW.

  The display unit 104 includes, for example, a display device such as an LCD (Liquid Crystal Display) or an organic EL (Electroluminescence) display. The display unit 104 displays an image under the control of the control unit 110.

  The operation unit 106 includes, for example, a user interface such as a button, a keyboard, or a mouse. The operation unit 106 receives a user's operation, and outputs information corresponding to the received operation to the control unit 110. The operation unit 106 may be a touch panel configured integrally with the display unit 104.

  The control unit 110 includes, for example, an acquisition unit 112, a data processing unit 114, and an output control unit 116. The data processing unit 114 is an example of a “generation unit”.

  The components of the control unit 110 are realized by a processor such as a central processing unit (CPU) executing a program stored in the storage unit 130. In addition, part or all of the components of the control unit 110 may be hardware such as LSI (Large Scale Integration), ASIC (Application Specific Integrated Circuit), FPGA (Field-Programmable Gate Array), or GPU (Graphics Processing Unit). May be realized by cooperation of software and hardware.

  The storage unit 130 is realized by, for example, an HDD (Hard Disc Drive), a flash memory, an EEPROM (Electrically Erasable Programmable Read Only Memory), a ROM (Read Only Memory), a RAM (Random Access Memory), or the like. The storage unit 130 stores design data 132 of each GIS unit UT, various processing results, and the like in addition to the program referred to by the processor. The design data 132 includes, for example, data on the three-dimensional shape and dimensions of the GIS 10 designed using CAD (Computer-Aided Design), and the three-dimensional shape of each GIS unit UT that is a component of the GIS 10 And data on dimensions. These data include, for example, GIS 10 and information defining a tolerance which is a difference between the allowable maximum dimension and the allowable minimum dimension of the GIS unit UT.

Processing flow
Hereinafter, the manufacturing method of a gas insulated switchgear and the installation method of a gas insulated switchgear are demonstrated using a flowchart. FIG. 6 is a flowchart showing a flow of a series of processing procedures of the manufacturing method of the gas insulated switchgear of the first embodiment and the installation method of the gas insulated switchgear. The processing procedure of this flowchart includes a manual operation process and a process operation using the installation support device 100 (computer).

  First, the worker combines a plurality of devices, for example, to manufacture a GIS unit UT having a transportable size as one unit (step S100).

  Next, the worker scans the manufactured GIS unit UT using the 3D scanner 50 (step S102). Thereby, the 3D scanner 50 generates three-dimensional shape data of the GIS unit UT.

  Next, the acquisition unit 112 of the installation support device 100 causes the communication unit 102 to communicate with the 3D scanner 50, and acquires the respective three-dimensional shape data of the plurality of GIS units UT from the 3D scanner 50 of the communication partner ( Step S104).

  Next, the data processing unit 114 combines the plurality of three-dimensional shape data acquired by the acquisition unit 112 into one, and virtually combines the plurality of GIS units UT into a third order configuration image of the GIS 10 Data indicating the original shape (hereinafter, referred to as GIS total assembly state data) is generated (step S106).

  For example, the data processing unit 114 models one virtual GIS 10 by connecting virtual GIS units UT indicated by each three-dimensional shape data to each other in a virtual space using 3DCG software. . The virtual space may be, for example, a three-dimensional space having a width, a depth, and a height, similar to the real space. When modeling the GIS 10 in a virtual space, the data processing unit 114 selects, for example, a GIS unit UT satisfying a predetermined condition from among a plurality of virtual GIS units UT.

  The GIS unit UT that satisfies the predetermined condition is, for example, a unit that is to be placed closest to the foundation of the installation target facility when the GIS 10 is actually assembled in the installation target facility. From another point of view, the GIS unit UT that satisfies the predetermined condition is the reference when the position (height) of the first main bus LN1 and the second main bus LN2 in the vertical direction z is used as a reference From the position in the vertical direction z, the bottom of the GIS unit UT (the lowermost surface or point in the vertical direction z) is the unit located the farthest.

  The data processing unit 114 selects a GIS unit UT connectable to the GIS unit UT that satisfies the selected predetermined condition from among the plurality of virtual GIS units UT, and this GIS unit UT is subjected to predetermined conditions in virtual space. Connect to the GIS unit UT that satisfies Furthermore, the data processing unit 114 further selects a connectable GIS unit UT to the GIS unit UT connected to the GIS unit UT satisfying the predetermined condition, and sequentially connects the selected GIS unit UT. Then assemble the GIS 10 on virtual space.

  Next, the data processing unit 114 performs a structural inspection of the overall configuration image of the GIS 10 indicated by the GIS total assembly state data (step S108). For example, as a structure inspection, the data processing unit 114 determines whether or not the combined GIS units UT interfere with each other in the overall configuration image of the GIS 10. The interference is, for example, that in the virtual space, spaces corresponding to each of the plurality of GIS units UT overlap each other.

  Also, for example, the data processing unit 114 performs, as a structural inspection, a dimension of the GIS 10 indicated by the design data 132 (hereinafter referred to as a design dimension) and a dimension of the virtually assembled GIS 10 (hereinafter referred to as an assembly dimension). The difference is determined, and it is determined whether this dimensional difference is within a prescribed tolerance range. As described above, in order to virtually assemble the GIS 10 based on the GIS unit UT disposed at the closest position to the foundation of the installation target facility, the dimensional error of the virtual GIS 10 is actually the installation target facility As in the case of assembling the GIS 10, it is accumulated in the vertical direction z upward with respect to the foundation of the installation target facility. As described above, at least the bottom surface of the GIS 10 does not fall below the foundation of the installation target facility because the GIS 10 is assembled based on the unit disposed at the closest position to the foundation of the installation target facility. As a result, it is not necessary to scrape the foundation of the installation target facility, and the height of the GIS 10 can be adjusted simply by inserting a member such as a thin plate (for example, a liner described later) into the gap formed between the foundations. it can.

  Next, the data processing unit 114 determines whether or not there is an abnormality in the overall configuration image of the GIS 10 virtually assembled as a result of the structure inspection (step S110). For example, in the case where at least two or more GIS units UT among the plurality of GIS units UT constituting the virtual GIS 10 interfere with each other, the data processing unit 114 generates an overall configuration image of the virtually assembled GIS 10 Determine that there is an abnormality. Also, for example, if the difference between the design dimension of the GIS 10 and the assembly dimension of the GIS 10 when assembled virtually is outside the tolerance range, the data processing unit 114 displays the entire configuration image of the GIS 10 assembled virtually. Determine that there is an abnormality. The process of S108 and S110 may be performed by the manufacturer or the installation operator of the GIS 10 instead of the installation support device 100.

  Next, if the data processing unit 114 determines that the output control unit 116 has no abnormality in the overall configuration image of the virtually assembled GIS 10, for example, the display unit 104 has no abnormality in the overall configuration image of the GIS 10 The first screen representing that is displayed (step S112).

  In addition, when the data processing unit 114 determines that the output control unit 116 has an abnormality in the overall configuration image of the GIS 10 virtually assembled, for example, the display unit 104 has an abnormality in the overall configuration image of the GIS 10 Is displayed (step S114).

  FIG. 7 is a diagram showing an example of the first screen, and FIG. 8 is a diagram showing an example of the second screen. For example, on each screen, the inspection result for each inspection item of the structural inspection is displayed as characters and symbols, and an external view (3DCG) of the overall configuration image of the GIS 10 virtually assembled is displayed. By displaying such a screen, the manufacturer or the operator can confirm the overall configuration image of the GIS 10 before actually assembling the GIS 10.

  Note that, instead of changing the display screen of the display unit 104 according to the determination result of the data processing unit 114, the output control unit 116 sends a content such as an image or text to the terminal device 70 which is an external device. The terminal device 70 may display the first screen or the second screen by sending

  According to the first embodiment described above, the three-dimensional shape of each of the plurality of GIS units UT constituting one GIS 10 is measured by the 3D scanner 50, and based on the measured three-dimensional shape data of the GIS unit UT. The GIS total assembly state data indicating the three-dimensional shape of the GIS 10 when the plurality of GIS units UT are virtually combined is generated, and before the GIS 10 is assembled using the plurality of GIS units UT, the GIS total assembly state data is generated. By examining the entire configuration image of the virtually assembled GIS 10 based on the above, for example, interference between units and an unacceptable assembly error can be detected. As a result, with the final overall configuration image when the GIS 10 is installed in the installation target facility, quality confirmation of the GIS 10 can be performed easily and without leaks with a certain accuracy.

  Further, according to the first embodiment described above, the presence or absence of an abnormality such as interference between units or an assembly error outside the tolerance range is determined by numerical calculation using three-dimensional computer graphics. Abnormality can be detected quantitatively and objectively without dependence.

  Further, according to the first embodiment described above, since the structural inspection is performed without actually assembling the GIS 10, the time required for the quality confirmation in the manufacturing process of the GIS 10 can be further shortened.

Second Embodiment
The second embodiment will be described below. In the first embodiment described above, it is determined as a structural inspection whether or not the difference between the design dimension of the GIS 10 and the assembly dimension is within the tolerance range. On the other hand, in the second embodiment, as a structural inspection, it is determined whether or not the difference between the design dimension and the assembly dimension of each GIS unit 10 configuring the GIS 10 is within the tolerance range. It is different from. Hereinafter, differences from the first embodiment will be mainly described, and descriptions of parts in common with the first embodiment will be omitted.

  FIG. 9 is a flowchart showing a flow of a series of processing procedures of a method of manufacturing a gas insulated switchgear of the second embodiment and a method of installing the gas insulated switchgear. The processing procedure of this flowchart includes a manual operation process and a process operation by the installation support device 100.

  First, the worker combines a plurality of devices, for example, to produce a GIS unit UT having a transportable size as one unit (step S200).

  Next, the worker scans the manufactured GIS unit UT using the 3D scanner 50 (step S202).

  Next, the acquisition unit 112 of the installation support device 100 causes the communication unit 102 to communicate with the 3D scanner 50, and acquires the respective three-dimensional shape data of the plurality of GIS units UT from the 3D scanner 50 of the communication partner ( Step S204).

  Next, the data processing unit 114 derives the difference between the design dimension of the GIS unit UT included in the design data 132 and the assembly dimension of the GIS unit UT indicated by the three-dimensional shape data as the structure inspection (step S206) It is determined whether the derived dimensional difference is within a prescribed tolerance range (step S208).

  For example, when the data processing unit 114 determines that the difference between the design dimension and the assembly dimension of the GIS unit UT is within the tolerance range, the output control unit 116 causes the display unit 104 to display the first screen (step S210). And, if it is determined by the data processing unit 114 that the difference is outside the tolerance range, the second screen is displayed on the display unit 104 (step S212).

  According to the second embodiment described above, by comparing the design data of the GIS unit UT with the three-dimensional shape data, among the plurality of GIS units UT, the GIS unit UT whose assembly dimension is not within the tolerance range Can be detected. As a result, anomalies in the external dimensions of the GIS unit UT can be found easily and without leak and with constant accuracy.

  Moreover, according to the second embodiment described above, similarly to the first embodiment, the time required for quality confirmation in the manufacturing process of the GIS 10 can be further shortened.

  Further, according to the second embodiment described above, in order to take account of dimensional errors accumulated when combining a plurality of devices as a unit, compared with the case where the tolerance is confirmed at least in units of devices configuring the GIS unit UT, The accuracy of structural inspection can be further improved.

Third Embodiment
The third embodiment will be described below. In the third embodiment, three-dimensional shape data of the installation environment in which the GIS 10 is installed is further acquired, and virtually assembled based on the three-dimensional shape data of the installation environment and the three-dimensional shape data of the GIS unit UT. This embodiment differs from the first and second embodiments in that the overall configuration image of the GIS 10 is inspected. The installation environment includes, for example, the above-mentioned foundation of the installation target facility (an example of the foundation structure), switches and transformers connected to the assembled GIS 10, transmission lines, existing transformation facilities such as transmission lines, steel towers, etc. It includes various structures whose position, size, etc. are taken into consideration when installing the GIS 10, such as a control panel for another facility, a building of an installation target facility, a step, a passage, and the like. Hereinafter, differences from the first and second embodiments will be mainly described, and descriptions of parts in common with the first and second embodiments will be omitted.

  FIG. 10 is a flow chart showing a flow of a series of processing procedures of the method of manufacturing the gas insulated switchgear of the third embodiment and the method of installing the gas insulated switchgear. The processing procedure of this flowchart includes a manual operation process and a process operation by the installation support device 100.

  First, the worker combines a plurality of devices, for example, to produce a GIS unit UT having a transportable size as one unit (step S300).

  Next, the worker scans the manufactured GIS unit UT using the 3D scanner 50 (step S302).

  Next, the acquisition unit 112 of the installation support device 100 causes the communication unit 102 to communicate with the 3D scanner 50, and acquires the respective three-dimensional shape data of the plurality of GIS units UT from the 3D scanner 50 of the communication partner ( Step S304).

  Next, the data processing unit 114 combines the three-dimensional shape data of the plurality of GIS units UT acquired by the acquisition unit 112 into one to generate GIS total assembly state data (step S306).

  On the other hand, the worker scans the installation environment for installing the GIS 10 in parallel with scanning the manufactured GIS unit UT using the 3D scanner 50 (step S308).

  Next, the acquisition unit 112 causes the communication unit 102 to communicate with the 3D scanner 50, and acquires three-dimensional shape data of the installation environment from the 3D scanner 50 of the communication counterpart (step S310).

  Next, the data processing unit 114 acquires three-dimensional shape data of the installation environment from the 3D scanner 50 by the acquisition unit 112, and further generates GIS total assembly state data, synthesizes these data to form a virtual The data (hereinafter referred to as GIS on-site installation state data) indicating the three-dimensional shape of the overall configuration image of the GIS 10 assembled in the installation environment is generated (step S312). As described above, the GIS on-site installation state data is data including GIS total assembly state data and three-dimensional shape data of the installation environment.

  For example, when the three-dimensional shape data of the installation environment includes three-dimensional shape data of the base surface (exposed surface) of the installation target facility, the data processing unit 114 determines the basis of the installation target facility in the common virtual space. A GIS unit UT satisfying a predetermined condition is placed on the base surface based on the surface. More specifically, in the virtual space, the data processing unit 114 makes the bottom (the lowermost surface or point in the vertical direction z) of the GIS unit UT that meets the predetermined condition contact the base surface of the installation target facility Place on At this time, the GIS unit UT satisfying the predetermined condition and the base surface may not necessarily be in contact with each other. For example, when the heights of the first main bus LN1 and the second main bus LN2 are the heights relative to the base surface of the installation target facility, the height from the base surface to the first main bus LN1 and the second main bus LN2 is Since it is impossible to change the height, the maximum dimension of the GIS unit UT in the vertical direction z that satisfies the predetermined condition is the height from the base surface to the first main bus LN1 and the second main bus LN2 in anticipation of occurrence of assembly error in advance. May be designed to be shorter than In such a case, in virtual space, a gap may be formed between the bottom of the GIS unit UT that satisfies the predetermined condition and the base surface.

  After disposing the GIS unit UT satisfying the predetermined condition, the data processing unit 114 sequentially connects another GIS unit UT to the GIS unit UT satisfying the predetermined condition, thereby scanning different one virtual space. Generate GIS on-site installation state data in which an object (installation environment and GIS unit UT) is present.

  Next, the data processing unit 114 derives the adjustment amount of the GIS unit UT based on the generated GIS on-site installation state data. The adjustment amount is, for example, an indicator of a distance dimension which quantitatively determines how much the position of the GIS unit UT is to be shifted in a part or all of the x, y, z directions. For example, the data processing unit 114 derives a larger adjustment amount as the difference between the design dimension of the GIS unit UT indicated by the design data 132 and the assembly dimension of the virtually assembled GIS unit UT is larger, and the difference is smaller. The smaller the adjustment amount is, the more

  More specifically, the data processing unit 114 derives the maximum length of the bellows BW (the maximum value of the telescopic movable range) as the adjustment amount with respect to the horizontal direction x and y of the GIS unit UT. Also, for example, the data processing unit 114 derives the number of used liners as an adjustment amount with respect to the vertical direction z of the GIS unit UT. The liner is, for example, a thin plate-shaped member, and is inserted between the bottom of the GIS unit UT or the gantry PD and the base. The thickness of each liner is approximately the same.

  FIG. 11 is a diagram for explaining the maximum length of the bellows BW. As described above, the bellows BW is connected between the bus integrated disconnectors 20a, between the bus integrated disconnectors 20b, and between the gas insulation buses 25. As shown in FIG. 6A, for example, when the assembly size of the GIS unit UT falls within the tolerance estimated at the time of design, the bellows BW is fastened to each device at the normal position P. The maximum length of the bellows BW at this time is taken as Da. On the other hand, as shown in Fig. (B), when the assembly dimension of the GIS unit UT does not fit within the tolerance or when the assembly dimension error of the GIS unit UT is within the tolerance but the assembly dimension of the GIS unit UT is large Thus, for example, it is necessary to shrink the bellows BW of the bellows structure by the length Db. The data processing unit 114 derives the maximum length (Da−Db) of the bellows BW as an adjustment amount regarding the horizontal direction x and y of the GIS unit UT. In addition, the bellows BW has a fixed maximum length (maximum of the movable range of expansion and contraction) by fixing the both ends thereof with a bolt BT or the like.

  FIG. 12 is a diagram for explaining the number of used liners. For example, when the bottom of the gantry PD on which the GIS unit UT is installed is designed to be in contact with the base surface of the installation target facility at the regular height H1, the base suffers a manufacturing error σ1 In the GIS unit UT including the gantry PD, a manufacturing error σ2 occurs. In such a case, a gap (σ1 + σ2) corresponding to the sum of σ1 and σ2 is generated between the bottom surface of the gantry PD and the base surface of the installation target facility. The data processing unit 114 derives this gap (σ1 + σ2) based on the three-dimensional shape data of the GIS unit UT and the three-dimensional shape data of the installation environment, and uses the liner necessary to fill this gap (σ1 + σ2) Deriving the number. More specifically, when the thickness of the liner is A and the number of used liners X is X, the data processing unit 114 solves X ≧ (σ1 + σ2) / A to obtain the number of used liners X by GIS It is derived as an adjustment amount regarding the vertical direction z of the unit UT.

  Next, the output control unit 116 transmits the content such as an image or text to the terminal device 70 using the communication unit 102, so that the adjustment amount derived by the data processing unit 114 is transmitted to the terminal device 70. Is displayed with a letter or the like (step S316). The output control unit 116 may cause the display unit 104 to display the third screen. The third screen may be, for example, a screen in which a virtual three-dimensional space in which the foundation of the installation target facility which is a part of the assembly environment and the overall configuration image of the GIS 10 exist is displayed by 3DCG.

  Next, the operator who views the third screen displayed on the terminal device 70 or the display unit 104 adjusts the maximum length of the bellows BW based on the adjustment amount, or prepares the liners for the number of used members. Then, preparation for the work of assembling the GIS unit UT is performed (step S318). To adjust the maximum length of the bellows BW is, for example, to adjust the fixing position of the bolt BT fixed to both ends of the bellows B as described above. By this, the processing of this flowchart ends.

  According to the third embodiment described above, as in the first and second embodiments, the time required for quality confirmation in the manufacturing process of the GIS 10 can be further shortened.

  Further, according to the third embodiment described above, since the adjustment amount of the GIS unit UT is derived and preparation is made in advance based on this adjustment amount, the working time at the time of assembling the GIS 10 can be shortened. . For example, since the bellows portion of the bellows BW is formed of a metal member such as stainless steel, the reaction force as a spring is large, and the contraction and adjustment of the bellows BW requires a large amount of labor. Working time tends to be long. On the other hand, since the bellows BW has a large reaction force as a spring, it is relatively easy to extend and adjust the bellows BW. Therefore, by preparing the bellows BW contracted in advance based on the adjustment amount derived by the data processing unit 114, the worker or the like does not need to adjust the contraction of the bellows BW on site, and the installation man-hours can be reduced. It is possible to reduce. As a result, the time for assembling the GIS 10 on site can be shortened.

  In addition, since the number of liners required is generally calculated while checking the dimensions of the actual GIS unit UT during the assembly operation, there is a tendency that the number of installation steps at the site tends to be large. In addition, there was a tendency for surplus to be generated after installation, as liners were prepared for all locations to fill the expected maximum gap. On the other hand, according to the third embodiment, since the liner can be prepared based on the adjustment amount derived by the data processing unit 114, the number of installation steps such as confirmation work on site can be reduced. it can. In addition, since the number of liners to be prepared can be kept to the minimum necessary, the burden of preparing the liners in advance can be reduced, or the number of liners carried can be reduced. Work efficiency can be improved.

(Other embodiments)
Hereinafter, other embodiments (modifications) will be described. For example, in the three-dimensional virtual space, the data processing unit 114 selects one or both of the horizontal direction x and y and the vertical direction z among one or more structures of the installation environment from which the three-dimensional shape data is acquired. With regard to, if it is determined whether or not there is a structure that interferes with the GIS unit UT placed on the foundation, and it is determined that a structure that interferes with the GIS unit UT is present, the structure is present in virtual space A space and a space near the space are set as an area where the GIS unit UT can not be installed (hereinafter referred to as an installation prohibited area), and the other space is an area where the GIS unit UT can be installed (hereinafter, It may be set as an installation permission area). Then, the output control unit 116 causes the screen of the terminal device 70 and the screen of the display unit 104 to display the virtual space in which the installation prohibition area and the installation permission area are set.

  FIG. 13 is a view schematically showing a virtual space in which the installation prohibition area and the installation permission area are set. In the illustrated example, the horizontal plane (xy plane) of the virtual space is schematically shown. As illustrated, by visualizing the installation prohibited area and the installation permitted area, the worker who sees this can recognize an object (an object having a high probability of interfering) existing in the installation prohibited area in advance before assembling the GIS 10. It can be removed or the structure of GIS 10 can be changed. As a result, the time for assembling the GIS 10 on site can be shortened.

  In the illustrated example, the installation prohibition area and the installation permission area are set with respect to the horizontal plane, but the invention is not limited thereto. The installation prohibition area and the installation permission area are set also for a plane including the vertical direction z as one dimension. May be done. That is, the installation prohibition area and the installation permission area may be set as the three-dimensional space. For example, the wall or column of the building of the installation target facility has a manufacturing error larger than that of the machined product GIS10. Therefore, by measuring the three-dimensional shape of the structure having a large error, the distance between the structure such as a wall or a column and the GIS 10 can be accurately grasped. As a result, it is not necessary to assemble the GIS 10 while sequentially measuring the distance to a wall or the like on site, and the time for assembling the GIS 10 on site can be shortened. The walls and columns of the installation target facility are an example of the "existing structure".

  In the example described above, when there is a structure that interferes with the GIS unit UT without separating the space, the data processing unit 114 sets the installation prohibited area in the virtual space, but the present invention is not limited thereto. For example, the data processing unit 114 determines whether or not there is a structure unit that interferes with the GIS unit UT or the worker who assembles the GIS unit UT, such as electrical interference or electromagnetic interference, etc. You may judge. For example, if the bushing 15 is already installed on the foundation of the installation target facility, this bushing 15 has a three-dimensional shape measured as one structure of the installation environment. In this case, the virtual space includes the foundation of the installation target facility and the bushing 15 installed on the foundation. The bushing 15 is another example of the “existing structure”.

  In such a case, the data processing unit 114 determines whether the bushing 15 interferes with the GIS unit UT or the worker at a space. For example, the bushing 15 exposes a high voltage portion because the wire is connected from the steel tower, and when assembling the GIS 10, it is necessary to take a certain distance (safety separation distance) or more. The data processing unit 114 determines that structures that need to have such a safety separation distance interfere with the GIS unit UT or the worker at a space. Then, the data processing unit 114 includes an area where a structure such as the bushing 15 which needs to have a safe separation distance exists, and an area around the area where the structure exists (for example, an area for the safety separation distance). Set the combined area as the installation prohibited area. As a result, the operator can perform the assembling operation of the GIS 10 without approaching the structure such as the bushing 15 while recognizing the safe separation distance in the three-dimensional space.

  In the embodiment described above, when the data processing unit 114 actually assembles the GIS 10 in the installation target facility as the GIS unit UT that satisfies the predetermined condition, the data processing unit 114 is located closest to the foundation of the installation target facility. Although the GIS 10 has been described as being assembled on a virtual space based on the GIS unit UT to be arranged, the present invention is not limited to this. For example, the data processing unit 114 may select the GIS unit UT as a reference at the time of assembly of the GIS unit UT so that the total number of liners to be inserted between the data processing unit 114 and the foundation is reduced based on the footstep.

  FIG. 14 is a diagram for describing a method of selecting a GIS unit UT as a reference at the time of assembly of the GIS unit UT. For example, the basic section b is lower than the height of the section a by H 2. The length of the section b in the x direction is twice that of the section a. The step H2 is smaller than the thickness of one liner, and each GIS unit UT is designed to form a gap of at least the thickness of one liner with the foundation. I assume.

  Under such conditions, the data processing unit 114 assembles the GIS 10 in a virtual space based on, for example, the GIS unit UT to be installed in the section b of the foundation. This makes it possible to reduce the total number of liners to be inserted between the base and the GIS unit UT to be installed in the section a, for example.

A program stored in a portable storage medium mounted on the secondary storage device 100-5 or the drive device 100-6 is expanded on the RAM 100-3 by a DMA controller (not shown) or the like and executed by the CPU 100-2. Thus, the control unit 110 is realized. The program to which the control unit 110 refers may be downloaded from another device via the communication network NW.
