Description

[Technical Field]

[0001] The present disclosure relates to an electrical equipment design support system that supports the design of electrical equipment including the configuration of electrical paths and the configuration of breakers that open and close the electrical paths. [Background technology]

[0002] High-voltage power receiving equipment is used to receive power supplied by electric power companies in accordance with the user's equipment. The power received by the high-voltage power receiving equipment is supplied from the high-voltage power receiving equipment to a distribution board, and from the distribution board to load equipment, which is equipment that uses the power. Patent Document 1 is an invention of high-voltage power receiving equipment, in which the equipment necessary for high-voltage power reception is assembled within a box-shaped frame. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-96699 Summary of the Invention [Problem to be solved by the invention]

[0004] In order to install high-voltage power receiving equipment, it is necessary to specify the specifications of the high-voltage power receiving equipment, including equipment for drawing power from the power company's distribution lines and trunk equipment for distributing power depending on the configuration of the distribution board.

[0005] To identify the specifications of high-voltage power receiving equipment, it is necessary to know the specifications of the distribution board that distributes power from the high-voltage power receiving equipment. Once the specifications of the distribution board are identified, it becomes possible to create high-voltage power receiving equipment information related to the specifications of the high-voltage power receiving equipment.

[0006] In this way, the high-voltage power receiving equipment information and the distribution board information are created together. However, due to the structural background of the construction industry, it is actually time-consuming to specify the specifications of the high-voltage power receiving equipment and the distribution board.

[0007] Specifically, when specifying the specifications for a distribution board, first, the building equipment designer formulates rough specifications based on their experience and know-how. Then, the electrical designer designs the detailed specifications for the distribution board, and these detailed specifications are transmitted to the manufacturer via a trading company or agency. The information transmitted to the manufacturer via the trading company or agency includes design drawings and load information. The manufacturer specifies the distribution board specifications based on the detailed specifications transmitted from the trading company or agency. At this time, the detailed specifications required to specify the distribution board specifications are not standardized among companies, so it can take time to decipher the information required to specify the distribution board specifications from the detailed information, and the manufacturer may select the wrong product number. This is what makes specifying distribution board specifications so time-consuming.

[0008] Since specifying the specifications for the distribution board is time-consuming, specifying the specifications for the high-voltage power receiving equipment is also time-consuming. As such, specifying the specifications for the distribution board and the high-voltage power receiving equipment in electrical equipment design requires a lot of work for the designer, so there is a need to make the selection process more efficient.

[0009] An object of the present invention is to provide a system that makes it possible to more easily obtain electrical equipment design information in order to more efficiently design electrical equipment. [Means for solving the problem]

[0019] The present embodiment will be described below with reference to the accompanying drawings. Therefore, the same reference numerals are used to designate the same components in the drawings as much as possible to avoid duplication. The explanation will be omitted.

[0020] In the first embodiment, a case will be described in which a cubicle-type high-voltage power receiving facility is used as the high-voltage power receiving facility.

[0021] As shown in FIG. 1 , the electrical equipment design support system C of this embodiment includes a design support server 10 that can communicate with terminal devices 20-23 via a network line N. The terminal devices 20-23 are operated by contractors involved in the design of electrical equipment when designing a building, specifically, architectural designers, facility designers, electrical designers, and staff from trading companies and agencies. For convenience, the architectural designers, facility designers, electrical designers, and staff from trading companies and agencies will be collectively referred to as "electrical equipment contractors" below. The terminal devices 20-23 include an input device that can input information about the electrical equipment, a display device that displays information about the selected electrical equipment, and the like. In this embodiment, the terminal devices 20-23 correspond to the input unit in the electrical equipment design support system C.

[0022] The design support server 10 comprehensively manages information related to the design of electrical equipment. The design support server 10 is configured around a microcomputer and includes a CPU and storage devices such as a ROM and RAM. The design support server 10 executes various processes by executing programs pre-stored in the ROM. As shown in FIG. 2, the design support server 10 has, as functional components, a receiving unit 101, a transmitting unit 102, a creating unit 103, an updating unit 104, and a storage unit 105.

[0023] The receiving unit 101 acquires information input to the terminal devices 20 to 23 and stores the acquired input information in the storage unit 105. The transmitting unit 102 displays the information stored in the storage unit 105 on the terminal devices 20 to 23 based on the operation of the terminal devices 20 to 23. For example, when an architectural designer inputs information related to electrical equipment into the terminal device 20, the receiving unit 101 stores the input information in the storage unit 105. When a facility designer, an electrical designer, or an employee of a trading company or an agency accesses the design support server 10 from the terminal devices 21 to 23, the input information of the architectural designer is read from the storage unit 105 and transmitted to the terminal devices 21 to 23 by the transmitting unit 102. The transmitted information is displayed on the terminal devices 21 to 23. The facility designer, etc. can view the input information of the architectural designer via the terminal devices 21 to 23. With this configuration, input information of electrical equipment-related contractors can be centrally managed in the design support server 10.

[0024] Furthermore, the design support server 10 creates electrical equipment design information to be used in designing a building based on the electrical equipment configuration information received from the terminal devices 20-23.

[0025] When an electrical equipment contractor inputs electrical equipment configuration information into terminal devices 20 to 23, the input information is transmitted to the terminal and acquired by the receiving unit 101. Based on the electrical equipment configuration information acquired by the receiving unit 101, the creating unit 103 creates electrical equipment design information including the configuration of electrical paths connected to loads and the configuration of breakers that open and close the electrical paths.

[0026] 3 and 4, the procedure for creating electrical equipment design information executed by the design support server 10 will be specifically described. For convenience, the following description will be given taking as an example a case where the design support server 10 is accessed from a terminal device 21.

[0027] In step S201, the transmitting unit 102 of the design support server 10 transmits data for displaying the case information input screen shown in Fig. 5(A) to the terminal device 21. The terminal device 21 displays the case information input screen.

[0028] The project information input screen displays the following items: "Subject," "Constructor," "Address," "Contact Person," "Specifications," "Building Type," "Salt Resistance," "Paint Color," "Power Pipe," "Frequency," "Inlet Line Size," "VCT Space," "PAS Information," "LA," "Inlet," "Inlet Method," "Construction Start Date," "Completion Date," "Cubicle Installation Date," "Panel Installation Date," "Demand Rate," "Light Panel Branch Frame Capacity," "Top Floor," "Bottom Floor," "Seismic Resistance Class," and "QP Installation Location."

[0029] On the project information input screen, any information can be entered into the fields "Subject," "Builder," "Address," "Person in Charge," "Construction Start Date," "Completion Date," "Panel Installation Date," and "Cubicle Installation Date." The "Subject" field is a section for entering the name of the construction project for a new building. The "Builder" field is a section for entering information about the builder. The "Address" field is a section for entering the address of the new building. The "Person in Charge" field is a section for entering information about the person in charge. The "Construction Start Date" field is a section for entering the start date of construction. The "Completion Date" field is a section for entering the completion date. The "Panel Installation Date" field is a section for entering the desired date for delivery of the panels. The "Cubicle Installation Date" field is a section for entering the desired date for delivery of the cubicles. Note that in order to identify a target project from among multiple projects, for example, "Subject" and "Address" may be required input fields, and the others may be optional input fields.

[0030] Of the items displayed on the project information input screen, the "Building type," "Salt resistance," "Paint color," "Power pipe interior," "Frequency," "Incoming line size," "VCT space," "PAS information," "Pull-in," "Demand rate," "Light panel branch frame capacity," "Seismic resistance class," and "QP installation location" items allow appropriate values ​​to be selected, and pre-set default values ​​are displayed. The "Top floor" and "Bottom floor" items allow you to select the floor number. Check boxes are displayed in the "Specifications" and "LA" items. The "Specifications" item is set to a default value.

[0031] In step S101, values ​​for each item on the project information input screen displayed on the terminal device 21 are input or selected, and transmitted to the design support server 10. Specifically, as shown in FIG. 5(B), values ​​are input or selected for each item on the project information input screen, and the "Register" button at the bottom of the screen is selected, whereby the project information is transmitted from the terminal device 21 to the design support server 10.

[0032] In step S202, the receiving unit 101 of the design support server 10 receives information from the terminal device 21 and acquires the case information. The acquired case information is stored in the storage unit 105 of the design support server 10.

[0033] In step S203, the transmitting unit 102 of the design support server 10 transmits the acquired list of cases to the terminal device 21.

[0034] In step S102, the terminal device 21 selects a target project for which electrical equipment design information will be created from the project list sent from the design support server 10, and sends information about the selected project to the design support server 10.

[0035] In step S204, the design support server 10 transmits equipment editing information for the target project to the terminal device 21. Specifically, data for displaying the equipment editing screen shown in Fig. 6(A) is transmitted to the terminal device 21.

[0036] The equipment edit screen 401 displays the following items: "equipment type," "installation location," "installation method," "mounting method," "panel name," "demand rate," "weight," and "dimensions."

[0037] The "Device Type" field is where the type of equipment is entered, either distribution board or facility board. A facility board is a distribution board for which the appropriate specifications for a certain piece of equipment have already been determined. The "Installation Location" field is where information about the floor on which the board will be installed is entered. The "Installation Method" field displays the environment where the board will be installed. The "Mounting Method" field is where the method for installing the board is entered. The "Panel Name" field is where the type of high-voltage power receiving equipment that supplies power to the distribution board is entered. For example, this could be a lighting distribution board or a power distribution board, which is equipment that transforms high-voltage power supplied from the power system and supplies it to the distribution board. The "Demand Rate" field is where the demand rate, which is the ratio of demand power to maximum power in the system to which the distribution board distributes power, is entered. The "Weight" and "Dimensions" fields are where their respective values ​​are displayed after the specifications of the distribution board have been determined.

[0038] Among the items displayed on the equipment editing screen, the items "equipment type," "installation method," "mounting method," and "demand rate" allow appropriate values ​​to be selected, and preset initial values ​​are displayed.

[0039] When the "Add Row" button on the device edit screen is selected, an input row is added. When the "Copy Row" button is selected, an input row is copied and added. When the delete checkbox is selected and the "Delete Row" button is selected, that input row is deleted.

[0040] In step S103, values ​​for each item on the equipment editing screen displayed on the terminal device 21 are input or selected, and the values ​​are transmitted to the design support server 10. Specifically, as shown in FIG. 6(B), values ​​are input or selected for each item on the equipment editing screen, and the "Register" button at the bottom of the screen is selected, whereby project information is transmitted from the terminal device 21 to the design support server 10. Here, it is indicated that three rows, i.e., three distribution boards or facility boards, are to be edited. As the "equipment type," a type of "distribution board" or "facility board" is input. As the "installation method," indoor, outdoor, and waterproof (no roof) are selected. As the "mounting method," exposed wall-mounted, embedded, and freestanding are selected. In addition, values ​​are selected for the "demand rate" item. As the "register" button at the bottom of the screen is selected, basic equipment information is transmitted from the terminal device 21 to the design support server 10.

[0041] In step S205, the receiving unit 101 of the design support server 10 acquires the basic device information. The acquired information is stored in the storage unit 105. Furthermore, if the basic device information is updated, the updating unit 104 updates the basic device information in the storage unit 105.

[0042] In step S206, the design support server 10 transmits detailed editing information for each distribution board based on the basic equipment information to the terminal device 21. Specifically, as shown in FIG. 7(A), an electrical equipment detailed editing screen is transmitted to the terminal device 21.

[0043] On the electrical equipment detailed editing screen, the following items are displayed at the top of the screen: "Equipment type," "Installation location," "Installation method," "Mounting method," "Panel name," "Demand rate," "Paint color," "Weight," "Dimensions," "Total power," "Number of systems," "Terminal unit," "Power supply unit," and "Timer unit."

[0044] The electrical equipment detailed editing screen also displays the following items: "Main Line No.", "Phase Wire Type / Voltage", "Main Type", "AT", "Main Line", and "WHM". "AT" is an abbreviation for the breaker ampere trip. In the following, the breaker ampere frame will be abbreviated as "AF".

[0045] In addition, the electrical equipment detailed editing screen displays the following items: "Circuit number," "Load name," "Connection position," "Destination," "Power consumption," "Breaker type," "Number of poles," "AT," "WHM," "Capacitor," "Main circuit," "Control circuit," "MC," "Timer TS," "AS," "Monitoring circuit," "Earth leakage alarm," "Alarm contact," "Monitoring panel (operation)," "Monitoring panel (stop)," "Monitoring panel (fault)," "Monitoring panel (monitoring)," "Heat-resistant section," and "Remarks."

[0046] On the electrical equipment detail editing screen, the following fields are pre-entered with information stored in storage unit 105: "equipment type," "installation location," "installation method," "mounting method," "panel name," "demand rate," and "paint color."

[0047] A value can be entered in the "Main line No." field. Appropriate values ​​can be selected for the "Phase / Wire System / Voltage," "Main Line Type," "AT," "Main Line," and "WHM" fields, and preset initial values ​​are displayed.

[0048] Values ​​can be entered in the "Load name," "Power consumption," and "Remarks" fields. Appropriate values ​​can be selected for the "Quantity," "Circuit number," "Connection position," "Breaker type," "Number of poles," "AT," "WHM," and "Heat-resistant section" fields, and pre-set initial values ​​are displayed. Circuit selection buttons are displayed for the "Main circuit," "Control circuit," and "Monitoring circuit" fields.

[0049] Check boxes are displayed for the items "Capacitor," "MC," "Timer TS," "AS," "Monitoring circuit," "Earth leakage alarm," "Alarm contact," "Monitoring panel (operation)," "Monitoring panel (stop)," "Monitoring panel (fault)," and "Monitoring panel (monitoring)."

[0050] When the "Add Load" button on the Electrical Equipment Detail Edit screen is selected, input rows such as "Load Name" can be added. When the "Add Sub-Main" button is selected, the input items for the sub-main are displayed. When the "Add Main" button is selected, the input items for the main are added.

[0051] When the "Add sub-main" button is selected, the following items are added: "Sub-main type," "Voltage," "AF," "Sensitivity current," and "WHM." In addition, the following items are added as branch line items: "Circuit number," "Load name," "Connection position," "Destination," "Power consumption," "Breaker type," "Number of poles," "AT," "WHM," "Capacitor," "Main circuit," "Control circuit," "MC," "Timer TS," "AS," "Monitoring circuit," "Earth leakage alarm," "Alarm contact," "Monitoring panel (operation)," "Monitoring panel (stop)," "Monitoring panel (fault)," "Monitoring panel (monitoring)," "Heat-resistant section," and "Remarks."

[0052] In step S104, on the terminal device 21, values ​​are entered into the ``Load name,'' ``Quantity,'' and ``Power consumption'' fields on the electrical equipment detail editing screen 402 by operating the ``Add load'' button, ``Add sub-main'' button, and ``Add main'' button, and the values ​​are sent to the design support server 10.

[0053] In step S207, the receiving unit 101 of the design support server 10 acquires load information. The load information includes "load name," "power consumption," and "number" for each branch line. The load information can be used to identify the load of the electrical equipment.

[0054] The creation unit 103 of the design support server 10 creates distribution board information including the configuration of the main line and the configuration of the branch line based on the load information and using predetermined arithmetic expressions, maps, etc.

[0055] The main line configuration includes the main line number corresponding to the "Main Line No." item, the main line phase and line type and main line voltage corresponding to the "Phase and Wire Type / Voltage" item, the type of main breaker located on the main line corresponding to the "Main Type" item, the AF of the main breaker, the AT of the main breaker corresponding to the "AT" item, the type of main line corresponding to the "Main Line" item, and whether or not there is a WHM. The main line phase and line type and main line voltage correspond to the power distribution method.

[0056] The branch line configuration includes the supply voltage to the load connected to the branch line corresponding to the "Voltage" item, the type of branch breaker corresponding to the "Breaker type" item, the number of poles of the branch breaker corresponding to the "Number of poles" item, the AF of the branch breaker, and the AT of the branch breaker corresponding to the "AT" item.

[0057] Furthermore, the branch line configuration includes information about the following items on the electrical equipment detail editing screen: "Circuit Number," "Load Name," "Connection Location," "Destination," "Power Consumption," "Breaker Type," "Number of Poles," "AT," "WHM," "Capacitor," "Main Circuit," "Control Circuit," "MC," "Timer TS," "AS," "Monitoring Circuit," "Earth Leakage Alarm," "Alarm Contact," "Monitoring Panel (Operation)," "Monitoring Panel (Stop)," "Monitoring Panel (Fault)," "Monitoring Panel (Monitoring)," and "Heat-Resistant Section." Also, in order to display appropriate items for the load information, the "Connection Location" item may be displayed as the "Send" item, and a "Remote Control" item may also be provided.

[0058] The distribution board information created by the creation unit 103 is stored in the storage unit 105. The transmission unit 102 transmits to the terminal device 21 an electrical equipment detail editing screen 402 updated based on the stored distribution board information.

[0059] In step S105, the updated electrical equipment detail editing screen is displayed on the terminal device 21.

[0060] Specifically, a map showing the relationship between the type of load and the configuration of the branch line is stored in advance in the storage device of the design support server 10. The creation unit 103 uses this map to select the supply voltage to the load, the type of branch breaker, the number of poles of the branch breaker, and the AT of the branch breaker based on the type of load entered in the "load name" field. For example, for a trunk line whose "trunk line No." in FIG. 7B is "GL-102," when the type of load entered in the "load name" field is "outlet," the creation unit 103 selects "100 V" as the supply voltage, "MCCB" as the type of branch breaker, "2 poles" as the number of poles of the branch breaker, and "75AT" as the AT of the branch breaker based on the map corresponding to the outlet. The values ​​of the supply voltage to the selected load, the type of branch breaker, the number of poles of the branch breaker, and the AT of the branch breaker are displayed in the "Voltage," "Breaker type," "Number of poles," and "AT" fields for the trunk line with the "Trunk No." of "GL-102" in Figure 7(B).

[0061] The creation unit 103 also selects a type of main breaker based on the determined type of branch breaker. The selected type of main breaker is displayed in the "main breaker type" field.

[0062] Furthermore, the storage device of the design support server 10 pre-stores a map showing the relationship between the type of distribution panel that supplies power to the panel and the phase wiring system of the main line. The creation unit 103 uses this map to select the phase wiring system of the main line from the type of distribution panel input in the "Panel Name" field. For example, if the type of distribution panel input in the "Panel Name" field indicates an electric lighting distribution panel, the creation unit 103 selects a single-phase three-wire system as the phase wiring system of the main line. Furthermore, the creation unit 103 selects the supply voltage to the main line based on the supply voltage to the load supplied from the branch line. The selected phase wiring system and supply voltage to the main line are displayed in the "Phase Wiring System / Voltage" field.

[0063] The creation unit 103 also calculates the total value of the values ​​entered in each "power consumption" field, i.e., the total value of the power consumption of the load. Based on this total value of the power consumption of the load, the number of poles of the branch breakers, the AF of the branch breakers, the AT of the branch breakers, and the demand rate, the creation unit 103 selects the AF of the main breaker, the AT of the main breaker, and the type of main line using an arithmetic formula, a map, etc. It is also possible to take into account the effect of voltage drop according to the length of the main line. The selected total value of the power consumption of the load, the AT of the main breaker, and the type of main line are displayed in the "total power," "AT," and "main line type" fields, respectively.

[0064] The storage device of the design support server 10 stores in advance information on products appropriate for the selected main line configuration and branch line configuration. The creation unit 103 selects a specific product from the selected distribution board information. The creation unit 103 calculates the weight and dimensions of the entire board based on the selected product. The calculated weight and dimensions are displayed in the "Weight" and "Dimensions" fields.

[0065] As described above, when values ​​are entered in the "Load name" and "Power consumption" fields on the panel information detail input screen 400, values ​​determined by the design support server 10 are automatically entered in the "Phase wire type / voltage", "Main breaker type", "Main AT", "Total power", "Main line", "Voltage", "Branch breaker type", "Number of poles", "Branch AT", "Total power", "Weight", and "Dimensions" fields in FIG. 7.

[0066] In step S106, if there is a change by input or selection to an item corresponding to the configuration of the main line or an item corresponding to the configuration of the branch line on the electrical equipment detail editing screen 402 displayed on the terminal device 21, the terminal device 21 transmits the update information to the design support server 10.

[0067] In step S208, the update unit 104 of the design support server 10 updates the distribution board information using a predetermined arithmetic expression, map, etc., based on the update information received by the receiving unit 101. The updated distribution board information is accumulated in the storage unit 105. The transmitting unit 102 transmits an updated electrical equipment detail editing screen based on the updated distribution board information to the terminal device 21.

[0068] In step S107, the updated electrical equipment detail editing screen is displayed on the terminal device 21.

[0069] In step S108, it is determined whether or not there have been any changes to the items on the electrical equipment detail editing screen displayed on the terminal device 21. If there have been any changes to the items, the process returns to step S106 and repeats. If there have been no changes, the process proceeds to the next step.

[0070] In this way, the design support server 10 creates distribution board information by successively updating the distribution board information in response to input of load information.

[0071] Here, it can be determined that no changes have been made when the "Save" button at the bottom of the electrical equipment detail editing screen displayed on the terminal device 21 is selected. Although the creation of one distribution board information has been described, distribution board information can be created for each of multiple distribution boards.

[0072] In step S209, the creation unit 103 of the design support server 10 selects cubicle specifications using predetermined arithmetic expressions, maps, etc. based on the distribution board information stored in the storage unit 105, and creates high-voltage power receiving equipment information. Specifically, the creation unit 103 uses this map to select a transformer, a high-voltage side phase-advancing capacitor and reactor, a high-voltage side switch of the transformer, a low-voltage side breaker, a low-voltage side phase-advancing capacitor, an alarm device, a low-voltage option, and a transformer option, and creates high-voltage power receiving equipment information. The high-voltage side phase-advancing capacitor and reactor, and the high-voltage side switch of the transformer are the high-voltage side specifications. Also, the low-voltage side breaker and the low-voltage side phase-advancing capacitor are the low-voltage side specifications. The created high-voltage power receiving equipment information is stored in the storage unit 105.

[0073] In step S210, the transmitting unit 102 of the design support server 10 transmits the cubicle editing information to the terminal device 21. For example, as shown in Fig. 8, a cubicle specification editing screen is transmitted to the terminal device 21 based on the high-voltage power receiving equipment information.

[0074] The cubicle specification editing screen displays the following columns: "Basic Information," "Transformer," "High-Voltage Capacitor / Reactor," "High-Voltage Feed Information," "Low-Voltage SC (Static Capacitor) Device," "Alarm," "Low-Voltage Options," and "High-Voltage Options."

[0075] The "Basic Information" column displays the following items: "Breaker Type," "Transformer Type," "Color," "Housing," "FAN," and "Dr-SW." The "Transformer" column displays the following items: "No.", "Switch," "Phase Type," "Capacity," "LC Unit 1," "LC Unit 2," and "LC Unit 3." The "High-Voltage Capacitor / Reactor" column displays the following items: "SR," "Switch," "VMC," "SC," "SR / SC," and "Type." The "High-Voltage Feed Information" column displays only the "Switch." The "Low-Voltage SC Device (LC Unit)" column displays the "MCCB" and "MC." The "Alarm" column displays the "Indicator Lamp," "Fault Buzzer," "External Alarm," and checkboxes corresponding to various alarms. The "Low-Voltage Options" column displays the "Crimp Terminal / Insulating Cap," "Breaker Secondary Terminal Block," "Breaker with AL," and "With THR." The "Transformer Options" column displays the "Dial Thermometer," "Isolator Rubber," "LGR," and "Meter."

[0076] For each item in the "Basic Information" column, a value is selected and displayed based on the project information. Regardless of the project information, an appropriate initial value can also be selected and displayed for each item in the "Basic Information" column. For each item in the "Transformer," "High-Voltage Capacitor / Reactor," "High-Voltage Feed Information," "Low-Voltage SC Device (LC Unit)," and "Alarm" columns, a value corresponding to the created high-voltage power receiving equipment information is selected and displayed.

[0077] The "Transformer," "High-Voltage Capacitor / Reactor," "High-Voltage Feed Information," and "Low-Voltage SC Device (LC Unit)" columns have "Add Row" and "Delete Row" buttons, which can be used to change the number of rows in each column.

[0078] In step S109, if a change is made by selection for each item on the cubicle specification editing screen displayed on the terminal device 21, the terminal device 21 transmits update information to the design support server 10.

[0079] In step S211, the update unit 104 of the design support server 10 updates the high-voltage power receiving equipment information using a predetermined calculation formula, map, etc., based on the update information received by the receiver 101. The updated high-voltage power receiving equipment information is accumulated in the storage unit 105. The transmitter 102 transmits to the terminal device 21 an updated cubicle specification editing screen based on the updated high-voltage power receiving equipment information.

[0080] In step S110, the updated cubicle specification editing screen is displayed on the terminal device 21.

[0081] In step S111, it is determined whether or not there have been any changes to the items on the cubicle specification editing screen displayed on the terminal device 21. If there have been any changes to the items, the process returns to step S109 and repeats. If there have been no changes, the process proceeds to the next step.

[0082] For example, consider a case where the number of transformers is changed from two to one on the cubicle specification editing screen. Here, before the number was reduced, one transformer was connected to the lighting distribution panel, and the other was connected to the power distribution panel. In this state, suppose the number of rows in the "Transformer" column on the cubicle specification editing screen is changed, that is, the number of transformers is changed to one. In this case, the update unit 104 updates the high-voltage power receiving equipment information based on this update information so that one transformer can cover the total load capacity of the lighting distribution panel and the power distribution panel.

[0083] Here, if the "Save" button at the bottom of the cubicle specification editing screen displayed on the terminal device 21 is selected, it can be determined that no changes have been made.

[0084] In step S210, the transmitting unit 102 of the design support server 10 can also transmit a cubicle specification detail editing screen to the terminal device 21 based on the high-voltage power receiving equipment information, as shown in FIG.

[0085] The cubicle specification detailed editing screen displays the following items: "No.", "Transformer", "Capacity", "Breaker type", "Trip capacity", "Type", "Panel name", "Main line", "Load capacity", and "WHM".

[0086] The "No." field displays the transformer number. The "Transformer" field displays the low-voltage side phase wiring system and the voltage supplied to the panel. The "Capacity" field displays the rated capacity of the transformer. The "Breaker type" field displays the type of breaker on the low-voltage side. The "Trip capacity" field displays the AT of the breaker on the low-voltage side. The "Type" field displays the type of panel that receives power distribution from the high-voltage power receiving equipment. The "Panel name" field displays the name of the panel that receives power distribution from the high-voltage power receiving equipment. The "Main line" field displays the main line number. The "Load capacity" field displays the load capacity of the panel that receives power distribution from the high-voltage power receiving equipment. The "WHM" field displays whether or not a power meter is installed. This information is included in the high-voltage power receiving equipment information for the transformer selected in step S209.

[0087] The values ​​displayed for each of the items "No.", "Transformer", "Capacity", "Breaker Type", "Trip Capacity", "Type", "Panel Name", "Main Line", "Load Capacity", and "WHM" correspond to the high-voltage power receiving equipment information that has been created.

[0088] In step S109, if any change has been made to any of the items on the cubicle specification detail editing screen 502 displayed on the terminal device 21, the terminal device 21 transmits the updated information to the design support server 10.

[0089] In step S211, the update unit 104 of the design support server 10 updates the high-voltage power receiving equipment information using a predetermined calculation formula, map, etc., based on the update information received by the receiver 101. The updated high-voltage power receiving equipment information is stored in the storage unit 105. The transmitter 102 transmits to the terminal device 21 an updated cubicle specification detail editing screen based on the updated high-voltage power receiving equipment information.

[0090] In step S110, the updated cubicle specification details editing screen is displayed on the terminal device 21.

[0091] In step S111, it is determined whether or not there are any changes to the items on the cubicle specification detail editing screen displayed on the terminal device 21. If there are any changes to the items, the process returns to step S109 and repeats. If there are no changes, the process proceeds to the next step.

[0092] Here, if the "Save" button at the bottom of the cubicle specification details editing screen displayed on the terminal device 21 is selected, it can be determined that no changes have been made.

[0093] In step S212, the creation unit 103 of the design support server 10 creates a panel list, a main line diagram, a distribution panel list, a panel outline drawing, a panel wiring diagram, a cubicle outline drawing, a high-voltage power receiving equipment wiring diagram, and an estimate based on the distribution panel information and the high-voltage power receiving equipment information. The created diagrams, tables, lists, and estimates are stored in the storage unit 105.

[0094] The panel list is a list that summarizes the overall configuration of each panel that receives electricity from high-voltage power receiving equipment, including the configuration of the main line and the configuration of the branch line. Figure 10 is an example of a panel list.

[0095] Based on the distribution board information, the creation unit 103 creates the following items: "Installation method," "Mounting method," "Board name," "Phase wire type," "Voltage," "Main line No.", "Total power," "Main breaker," "Number of poles," "AF," "AT," "Primary feed," "Breaker type," "AF," "AT," "Load name," and "Power consumption" shown in Fig. 10. Furthermore, the creation unit 103 creates a "Main AF" item based on the selected main AF, and a "Branch AF" item based on the branch AF.

[0096] In addition, based on the distribution board information, the creation unit 103 creates the items "Main circuit," "Control circuit," "Monitoring circuit," "Earth leakage alarm," "Alarm contact," "Monitoring panel (operation)," "Monitoring panel (stop)," "Monitoring panel (fault)," "Monitoring panel (monitoring)," "Fireproof compartment," and "Notes" shown in Figure 10.

[0097] A main line diagram shows the connection method and list of main lines that connect the high-voltage power receiving equipment and distribution board of a building. Figure 11 is an example of a main line diagram.

[0098] The distribution board list is a list of the names and quantities of high-voltage power receiving equipment and the distribution boards connected to it. In addition, an "equipment board" item is provided to indicate that a certain distribution board is an equipment board. Figure 12 is an example of a distribution board list.

[0099] The panel outline drawing is an outline drawing of a specific product suited to the distribution board information created by the design support server 10. Fig. 13 is an example of the panel outline drawing.

[0100] The panel wiring diagram is a wiring diagram created based on the specifications of each distribution board for each distribution board selected by the design support server 10. Fig. 14 is an example of a panel wiring diagram.

[0101] The cubicle outline drawing is an outline drawing of a specific product suited to the high-voltage power receiving facility configuration information created by the design support server 10. Fig. 15 is an example of a cubicle outline drawing.

[0102] The high-voltage power receiving facility wiring diagram is a wiring diagram created based on the specifications of each high-voltage power receiving facility selected by the design support server 10. Fig. 16 is an example of a high-voltage power receiving facility wiring diagram.

[0103] In step S112, the terminal device 21 requests the design support server 10 for drawings, tables, lists, and estimates.

[0104] In step S213, the transmitting unit 102 of the design support server 10 transmits the drawings, tables, lists, and estimates.

[0105] In step S113, the terminal device 21 displays various diagrams, tables, lists, and estimates.

[0106] According to the electrical equipment design support system C of this embodiment described above, the following actions and effects can be obtained.

[0107] The electrical equipment design support system C uses the transmission unit 102 as an output unit and can output configuration input information such as that shown in Fig. 7. This makes it easier for the creation unit 103 to obtain the load information required to create electrical equipment design information, making it possible to provide an electrical equipment design support system with improved convenience.

[0108] The electrical equipment configuration information includes at least one of distribution board information to which the load is connected and high-voltage power receiving equipment information regarding the specifications of the high-voltage power receiving equipment to which the distribution board is connected. This makes it possible to identify specific products based on at least one of the distribution board information and the high-voltage power receiving equipment information, thereby making it possible to obtain more detailed electrical equipment design information.

[0109] The distribution board information includes at least one of the configuration of the main line connecting the distribution board and the high-voltage power receiving equipment and the configuration of the branch lines branching off from the main line, and the creation unit 103 creates electrical equipment design information that specifies the specifications of the high-voltage power receiving equipment based on the distribution board information. This makes it possible to select high-voltage power receiving equipment that takes the distribution board information into account. It also makes it possible to specify the specifications of high-voltage power receiving equipment that integrates multiple distribution boards.

[0110] The main line configuration includes at least one of the following: the power distribution method of the main line, the type of main breaker placed on the main line, AF / AT of the main breaker, and the type of main line. This makes it possible to obtain the information necessary to create information about distribution boards from the electrical equipment design information, thereby enabling the creation of more appropriate electrical equipment design information.

[0111] The branch line configuration includes at least one of the voltage supplied to the load, the type of branch breaker, the number of poles of the branch breaker, and the AF and AT of the branch breaker. This makes it possible to obtain the information necessary to create information about the distribution board from the electrical equipment design information, thereby enabling the creation of more appropriate electrical equipment design information.

[0112] The high-voltage power receiving equipment information includes at least one of the transformer specifications, the high-voltage side specifications of the high-voltage power receiving equipment, and the low-voltage side specifications of the high-voltage power receiving equipment. This makes it possible to obtain the information necessary for creating information about the high-voltage power receiving equipment from the electrical equipment design information, thereby making it possible to create more appropriate electrical equipment design information.

[0113] The electrical equipment design information includes at least one of a main line diagram, a panel list, a distribution panel list, a panel outline drawing, a panel wiring diagram, and a high-voltage power receiving equipment wiring diagram. This allows the electrical equipment design information to be output as drawings to be used in actual electrical equipment construction work.

[0114] The high-voltage power receiving equipment in this embodiment is a cubicle-type high-voltage power receiving equipment. By being able to create electrical equipment design information for the cubicle-type high-voltage power receiving equipment, equipment designers and the like can easily design the high-voltage power receiving equipment.

[0115] The electrical equipment design information for cubicle-type high-voltage power receiving equipment includes a cubicle outline drawing. By being able to create a cubicle outline drawing, equipment designers and others can easily obtain the dimensional information for cubicle-type high-voltage power receiving equipment they need.

[0116] In this embodiment, the target is a cubicle-type high-voltage power receiving facility. However, even in cases other than the target of a cubicle-type high-voltage power receiving facility, i.e., in the case of an open-type high-voltage power receiving facility, it is possible to create electrical equipment design information that does not include a cubicle outline drawing by the electrical equipment design support system C.

[0117] The second embodiment will be described. The server device 10A is different from the first embodiment. The terminal devices 20 to 23 are operated by contractors involved in the design of electrical equipment when designing a building, specifically, architectural designers, facility designers, electrical designers, and staff from trading companies and agencies. Hereinafter, for convenience, architectural designers, facility designers, electrical designers, and staff from trading companies and agencies will be collectively referred to as "electrical equipment contractors." The terminal devices 20 to 23 are equipped with an input device that can input information about electrical equipment, a display device that displays information about selected electrical equipment, and the like. In this embodiment, the terminal devices 20 to 23 correspond to the input unit in the electrical equipment design support system C.

[0118] The server device 10A comprehensively manages information related to the design of electrical equipment. The server device 10A is configured around a microcomputer and includes a CPU and storage devices such as a ROM and RAM. The server device 10A executes various processes by executing programs pre-stored in the ROM. As shown in FIG. 17, the server device 10A includes an input information acquisition unit 100A, a storage unit 101A, a display unit 102A, a panel configuration selection unit 103A, and a table creation unit 104A.

[0119] The input information acquisition unit 100A acquires information input to the terminal devices 20-23 and stores the acquired input information in the storage unit 101A. The display unit 102A displays the information stored in the storage unit 101A on the terminal devices 20-23 based on the operation of the terminal devices 20-23. For example, when an architectural designer inputs information related to electrical equipment into the terminal device 20, the input information is stored in the storage unit 101A by the input information acquisition unit 100A. Therefore, when a facility designer, an electrical designer, or an employee of a trading company or an agency accesses the server device 10A from the terminal devices 21-23, the display unit 102A displays the input information of the architectural designer on the terminal devices 21-23. Therefore, the facility designer, etc. can view the input information of the architectural designer via the terminal devices 21-23. With this configuration, the input information of electrical equipment-related contractors can be centrally managed in the server device 10A.

[0120] Furthermore, when basic configuration information related to distribution boards used in building design is input to terminal devices 20-23, server device 10A automatically selects a distribution board configuration based on the information, and creates a distribution board list based on the selected distribution board configuration. Specifically, when an electrical equipment contractor inputs basic distribution board configuration information to terminal devices 20-23, the input information is acquired by input information acquisition unit 100A. Based on the distribution board basic configuration information acquired by input information acquisition unit 100A, panel configuration selection unit 103A automatically selects the configuration of a main line connecting the distribution board and the switchboard, and the configuration of branch lines branching from the main line. Table creation unit 104A creates a distribution board list that lists the configurations of the main lines and branch lines selected by panel configuration selection unit 103A.

[0121] Next, the procedure for creating a distribution board list table executed by server device 10A will be specifically described with reference to Figures 18 and 19. Note that the process shown in Figures 18 and 19 is executed when server device 10A is accessed from terminal devices 20 to 23. For convenience, the following description will be given taking as an example a case where server device 10A is accessed from terminal device 21.

[0122] As shown in FIG. 18, the input information acquisition unit 100A first displays a project input screen 30 as shown in FIG. 20 on the terminal device 21 as processing in step S10, and then acquires project information as processing in step S11. As shown in FIG. 20, the project input screen 30 displays input fields for "project title," "project address," "desired delivery date," and "building use." The "project title" field is a field for inputting the name of the construction work for a new building. The "project address" field is a field for inputting the address of the new building. The "desired delivery date" field is a field for inputting the date on which the distribution board is desired to be delivered. The "building use" field is a field for selectively inputting the type of building in which the distribution board will be installed, for example, whether it is an apartment building or a detached house. Note that in order to identify a target project from multiple projects, for example, "project title" and "project address" may be required input fields, and the other input fields may be optional.

[0123] 18, the input information acquiring unit 100A identifies a target case based on the case input items as the processing of step S12 following step S11, and then displays the distribution board information input screen 40 as the processing of step S13, as shown in Fig. 21. The distribution board information input screen 40 displays the following items: "Panel name," "Distribution method," "Main CB type," "Main AF / AT," "Total power," "Main line," "Distance," "Load name," "Power consumption," "Voltage," "Branch CB type," "Number of poles," and "Branch AF / AT."

[0124] Of these items, the "panel name," "load name," and "power consumption" items are required input items. The "panel name" item is a section for inputting the type of distribution panel that supplies power to the distribution panel. The distribution panel is a lighting distribution panel, a power distribution panel, etc., and is equipment that transforms high-voltage power supplied from the power system and supplies it to the distribution panel. The "load name" item is a section for inputting the type of load connected to the branch line of the distribution panel. The "power consumption" item is a section for inputting the power consumption of each load. In this embodiment, the information input in these distribution panel type, load type, and load power consumption items corresponds to the basic configuration information of the distribution panel.

[0125] As shown in FIG. 18, in step S14 following step S13, the panel configuration selection unit 103A acquires basic configuration information for the distribution panel based on the values ​​entered in the “Panel Name,” “Load Name,” and “Power Consumption” fields on the distribution panel information input screen 40. Then, in step S15, the panel configuration selection unit 103A selects the main line configuration and branch line configuration of the distribution panel from the basic configuration information of the distribution panel using a predetermined arithmetic expression, map, or the like. Furthermore, in step S16 following step S15, the panel configuration selection unit 103A displays the selected main line configuration and branch line configuration of the distribution panel on the distribution panel information input screen 40 shown in FIG. 21. The main line configuration includes the power distribution method of the main line, the type of main breaker installed on the main line, the ampere frame and ampere trip of the main breaker, and the type of main line. Hereinafter, for convenience, ampere frame and ampere trip are abbreviated as “AF / AT.” The branch line configuration includes the supply voltage to the loads connected to the branch line, the type of branch breaker to be placed on the branch line, the number of poles of the branch breaker, and the AF / AT of the branch breaker.

[0126] Specifically, a map showing the relationship between the load type and the branch line configuration is pre-stored in the storage device of the server device 10A. The panel configuration selection unit 103A uses this map to select the supply voltage to the load, the branch breaker type, the number of poles of the branch breaker, and the AF / AT of the branch breaker based on the type of load entered in the "load name" field. For example, if the type of load entered in the "load name" field is a "ventilation fan," the panel configuration selection unit 103A selects "100 V" as the supply voltage, "Molded-Case Circuit Breakers (MCCB)" as the type of branch breaker, "2 poles" as the number of poles of the branch breaker, and "60 AF / 20 AT" as the AF / AT of the branch breaker based on the map corresponding to the ventilation fan. Then, the panel configuration selection unit 103A displays the supply voltage to the selected load, the type of branch breaker, the number of poles of the branch breaker, and the AF / AT values ​​of the branch breaker in the respective items of "Voltage," "Branch CB type," "Number of poles," and "Branch AF / AT" shown in Figure 21.

[0127] In addition, the panel configuration selection unit 103A selects the type of main breaker based on the determined type of branch breaker, and displays the selected type of main breaker in the "Main CB type" item shown in Figure 21.

[0128] Furthermore, a map showing the relationship between the type of distribution panel and the power distribution method of the main line is stored in advance in the storage device of the server device 10A. The panel configuration selection unit 103A uses this map to select the power distribution method of the main line from the type of distribution panel input in the "Panel Name" field. For example, if the type of distribution panel input in the "Panel Name" field is a lighting distribution panel, the panel configuration selection unit 103A selects a single-phase three-wire system as the power distribution method of the main line. Then, the panel configuration selection unit 103A displays the selected power distribution method of the main line in the "Power Distribution Method" field shown in FIG. 21.

[0129] The panel configuration selection unit 103A also calculates the sum of the values ​​listed in the "Power Consumption" column, i.e., the total power consumption of the loads. The panel configuration selection unit 103A selects the AF / AT type of the trunk breaker and the type of main line using an arithmetic formula, a map, or the like, based on the total power consumption of the loads, the number of poles and AF / AT of the branch breakers, and the length of the main line. A predetermined value, e.g., 100 m, is used as the length of the main line. This main line length is used to select the configuration of the main line, taking into account the effect of voltage drop depending on the length of the main line from the distribution panel to the panel board. The panel configuration selection unit 103A then displays the total power consumption of the selected loads, the length of the main line, the AF / AT type of the main breaker, and the type of main line in the "Total Power," "Distance," "Main AF / AT," and "Main CB Type" columns shown in FIG. 21, respectively.

[0130] As described above, when values ​​are entered in the fields "panel name," "load name," and "power consumption" on the distribution panel information input screen 40, the values ​​determined by the panel configuration selection unit 103A are automatically entered in the fields "power distribution method," "main CB type," "main AF / AT," "total power," "main line," "distance," "voltage," "branch CB type," "number of poles," and "branch AF / AT."

[0131] As shown in FIG. 18, the input information acquisition unit 100A determines whether or not there has been a change in the items on the distribution board information input screen 40 as the process of step S17 following step S16. Specifically, the values ​​of the items on the distribution board information input screen 40 shown in FIG. 21, into which information determined by the panel configuration selection unit 103A is automatically input, namely, "power distribution method," "main CB type," "main AF / AT," "total power," "main line," "distance," "voltage," "branch CB type," "number of poles," and "branch AF / AT," can be changed arbitrarily. For example, the equipment designer can change the values ​​of these items arbitrarily by operating the terminal device 21. It can be changed.

[0132] As shown in Fig. 18, if the input information acquiring unit 100A makes a positive determination in the processing of step S17, i.e., if the value of the above item has changed from the information determined by the panel configuration selecting unit 103A, the input information acquiring unit 100A changes the display of the item as the processing of step S18. For example, as shown in Fig. 21, if the "Voltage" item corresponding to "Air Conditioner" in the "Load Name" is changed from "100 [V]" to "200 [V]", the input information acquiring unit 100A displays the border of this voltage item in a thick line. This makes it easier to identify the changed item.

[0133] As shown in FIG. 19 , the panel configuration selection unit 103A reselects the configuration of the main trunk line and the configuration of the branch line in step S19 following step S18, and displays the reselected configuration of the main trunk line and the configuration of the branch line on the distribution board information input screen 40 in step S20. For example, as shown in FIG. 21 , if the “voltage” item corresponding to “air conditioner” is changed from “100 V” to “200 V,” the panel configuration selection unit 103A recalculates the AF / AT value of the branch breaker corresponding to the air conditioner using an arithmetic formula, a map, or the like, based on the changed “voltage” value. Then, if the recalculated AF / AT value of the branch breaker is “60 AF / 30 AT,” the panel configuration selection unit 103A displays that value on the distribution board information input screen 40. In this case, the panel configuration selection unit 103A needs to change the AF / AT values ​​of the branch breakers from the original values ​​of "60AF / 20AT" to "60AF / 30AT," so the changed values ​​are displayed in bold, making the reselected values ​​easy to distinguish.

[0134] Furthermore, for example, when there is a change in the "distance" item, i.e., the length of the main line, the panel configuration selection unit 103A recalculates the configuration of the main line based on the changed length of the main line, and displays the calculation result on the distribution board information input screen 40. This allows the influence of voltage drop on the main line to be changed as desired.

[0135] As shown in FIG. 19 , when the processing of step S20 is executed, or when a negative determination is made in the processing of step S17 shown in FIG. 18 , the input information acquiring unit 100A displays an operation rate input screen 50 as shown in FIG. 22 on the terminal device 21 as processing of step S21. The operation rate input screen 50 allows the user to input an operation rate for each type of heavy load. In this embodiment, the types of heavy load used are "outlet system," "lighting system," and "air-conditioning system." For example, an equipment designer can operate the terminal device 21 to set the operation rates of the loads of the outlet system, the lighting system, and the air-conditioning system based on their own experience and preferences.

[0136] As shown in FIG. 19, the input information acquisition unit 100A acquires information on load availability based on the values ​​entered in the availability input screen 50 as the process of step S22 following step S21. Thereafter, the table creation unit 104A creates a distribution board list 60 as shown in FIG. 23 as the process of step S23. The distribution board list 60 is a list summarizing the overall configuration of the distribution board, including the configuration of the main line and the configuration of the branch lines. The table creation unit 104A creates the distribution board list 60 based on the values ​​of each item entered in the input screens shown in FIGS. 18 to 20.

[0137] Specifically, the table creation unit 104A creates the "Subject" field shown in Fig. 23 based on the name entered in the "Project Subject" field shown in Fig. 20. The table creation unit 104A also creates the "Panel Name, Panel Type," "Distribution Method, Trunk Number," and "Main Circuit" fields shown in Fig. 23 based on the information entered in the "Panel Name," "Distribution Method," and "Main CB Type" fields shown in Fig. 19. The table creation unit 104A also creates the "Split Model Type," "Number of Poles," "AF," "AT," "Voltage," and "Load Name" fields of the "Switch Capacity" shown in Fig. 23 based on the information entered in the "Load Name," "Voltage," "Branch CB Type," "Number of Poles," and "Branch AF / AT" fields shown in Fig. 19. In addition, the table creation unit 104A calculates the load capacity of each load using an arithmetic formula or the like based on the input information of "power consumption" shown in Figure 19 and the input information of the operating rates of each type of load shown in Figure 20, and displays the calculation results by type in the "load capacity" item shown in Figure 23.

[0138] Note that a predetermined symbol is entered in the "Circuit Number" field in the distribution board list 60 shown in Fig. 23. Also, any characters or values ​​can be entered in the "Drawing Name," "Remote Control," "Timer Circuit Type," and "Remarks" fields in the distribution board list 60.

[0139] 19 , in the process of step S24 following step S23, the table creation unit 104A displays the created distribution board list 60 on the terminal device 21 and stores the distribution board list 60 in the storage unit 101A of the server device 10A. This allows electrical equipment-related contractors other than equipment designers to view the distribution board list 60 by operating the terminal devices 20, 22, and 23.

[0140] According to the electrical equipment design support system C1 of this embodiment described above, the following actions and effects can be obtained.

[0141] (1) The electrical equipment design support system C1 includes an input information acquisition unit 100A that acquires basic configuration information of a distribution board from the terminal devices 20 to 23, a board configuration selection unit 103A that selects the configuration of a main line and a branch line based on the basic configuration information of the distribution board, and a table creation unit 104A that creates a distribution board list 60 that lists the configurations of the main line and the branch line selected by the board configuration selection unit 103A. As a result, the distribution board list 60 is created simply by the equipment designer or the like inputting the basic configuration information of the distribution board into the terminal devices 20 to 23, so the manufacturer can automatically create the distribution board list 60 without having to acquire detailed specifications of the distribution board from the equipment designer or the like. This makes it easier to create a distribution board list.

[0142] (2) The basic configuration information of the distribution board includes the type of distribution board corresponding to the item "board name" shown in Fig. 21, the type of load corresponding to the "load name" shown in Fig. 21, and the power consumption of the load corresponding to the "power consumption" shown in Fig. 21. As a result, when a facility designer or the like operates the terminal devices 20 to 23 and inputs values ​​into these items, the configuration of the main line and branch lines is automatically selected and a distribution board list 60 is created. This substantially simplifies the design of the distribution board, thereby improving convenience.

[0143] (3) The panel configuration selection unit 103A selects, as the configuration of the main trunk, a power distribution method of the main trunk corresponding to the item "power distribution method" shown in FIG. 21, a type of main breaker corresponding to the item "main CB type" shown in FIG. 21, AF / AT of the main breaker corresponding to the item "main AF / AT" shown in FIG. 21, and a "type of main trunk" corresponding to the item "trunk" shown in FIG. 21. In addition, the panel configuration selection unit 103A selects, as the configuration of the branch line, a supply voltage to the load corresponding to the item "voltage" shown in FIG. 21, a type of branch breaker corresponding to the item "branch CB type" shown in FIG. 21, the number of poles of the branch breaker corresponding to the item "number of poles" shown in FIG. 21, and AF / AT of the branch breaker corresponding to the item "branch AF / AT" shown in FIG. 21. This makes it possible to obtain information necessary for creating the distribution board list 60, thereby making it possible to create a more appropriate distribution board list 60.

[0144] (4) The information on the configuration of the main trunk line and the information on the configuration of the branch line selected by the panel configuration selection unit 103A can be changed as desired. This allows the equipment designer or the like to change the configuration of the main trunk line and the branch line as desired, making it possible to create a distribution panel list 60 that meets the intentions of the equipment designer or the like.

[0145] (5) The panel configuration selection unit 103A further selects the configuration of the main line based on information about the length of the main line corresponding to the "distance" item shown in Fig. 21. This allows the configuration of the main line to be selected taking into consideration the effect of voltage drop according to the length of the main line from the switchboard to the distribution board, making it possible to select a more appropriate configuration of the main line.

[0146] (6) The panel configuration selection unit 103A further selects the configuration of the main trunk line based on the information input in the load availability item shown in Fig. 22. This allows the equipment designer or the like to arbitrarily change the load availability, making it possible to create a distribution panel list 60 that meets the intentions of the equipment designer or the like.

[0147] The basic configuration information of the distribution board used to select the configuration of the main line and branch lines can be changed as desired. In addition, the information on the configuration of each of the main line and branch lines displayed on the distribution board information input screen 40 shown in Fig. 21 can also be changed as desired. Furthermore, the items included in the distribution board list 60 shown in Fig. 23 can also be changed as desired.

[0148] The panel configuration selection unit 103A may select the configuration of the main trunk without using information on the length of the main trunk corresponding to the "distance" item shown in Fig. 21. For example, the panel configuration selection unit 103A may select the configuration of the main trunk using a predetermined value as the voltage drop of the main trunk.

[0149] The table creation unit 104A may create the distribution board list 60 without using the load operation rates shown in Fig. 22. For example, the table creation unit 104A may create the distribution board list 60 by using predetermined values ​​as the load operation rates.
