Can be determined. In addition to such a configuration, the electrical facility management system according to the present invention realizes BIM (Building Information Model) of the electrical facility of the building by linking the electrical facility database of the building with the three-dimensional CAD of the building. Configuration is also adopted.

First, an overview of the electrical equipment installed in a building and managed by the electrical equipment management system according to the present invention will be described. FIG. 2 is a view for explaining an example of the installation state of the electrical equipment in the building. In FIG. 2, each load connected to the distribution board is not shown. Further, the electrical installation shown in FIG. 2 is just an example of the aspect of the electrical installation in the building, and the aspect of the electrical installation to which the electrical installation management system according to the present invention can be applied is limited to the example of FIG. Absent.

  The commercial power source is received by the power receiving and transforming equipment 40 provided in the building, and is stepped down to an appropriate voltage. The power thus reduced is subsequently supplied to the A system A system switchboard 50 and the B system A system switchboard 50 '. FIG. 3 is a block diagram of a tree structure from the A system switchboard 50 to each load. This block diagram corresponds to the in-building electrical installation shown in FIG.

  Here, in the present embodiment, as a branch from the power receiving and transforming equipment 40, the case of two systems of B system of A system is described as an example, but the number of branches from the power receiving and transforming equipment 40 is limited thereto. It is not a thing. In the following, the explanation will be made mainly using the A system as an example.

  In FIG. 3, “T” represents a transformer, “B” represents a breaker, “F” represents a frame to which the breaker is attached, and “L” represents a load supplied from a distribution board. There is. In addition, the difference in suffix attached to each letter indicates that they are different elements.

  From the A system distribution board 50, a distribution board provided on each floor by a plurality of main cables (in the present embodiment, the explanation is made based on an example in which one distribution board is provided on each floor) The number of boards is arbitrary). Moreover, in FIG.2 and FIG.3, although the case where only 3 system has branched from A system switchboard 50 is shown, it is not limited to this.

In addition, especially _B1i , _B2i , _B3i may be called the trunk side breaker of each electricity distribution panel.

  The breaker B is for interrupting the flow of electricity when an excessive current flows in the breaker B. The breaker B is physically attached to a frame F provided on a switchboard or distribution board. In proportion to the physical size of the frame F, a large capacity breaker B can be attached.

  The rated current when breaker B breaks is defined as ampere trip value (unit: ampere). Also, for the frame F, an ampere frame value (unit: ampere) is defined. For example, in the frame F having an ampere frame value of 30 A, breakers B up to 30 A can be attached.

  Moreover, as the load L, lighting, an air conditioner, or a power device such as an elevator is assumed.

From the power receiving and transforming equipment 40, the power received at the breaker B _A is stepped down by the transformer T _A , and subsequently supplied to the breakers B _1o , B _2o , B _3o .

Next, the flow of power from the A-system switchboard 50 to the load L will be described by taking the power supplied from the breaker B _1o attached to the frame F _1o of the A-system switchboard 50 as an example. Power is supplied from the breaker B _1o to the breaker B _1i attached to the frame F _1i of the first distribution board 71 by the first main trunk cable 61 (W ₁ ).

The power supplied to the breaker B _1i is branched and supplied to the breakers B _{11 to} B _1X attached to the frames F _{11 to} F _1X . Furthermore, through these breakers B ₁₁ to B _1X, power is supplied to each load L ₁₁ to L _1X.

Summary In the electrical equipment in the building configured as described above, for example, a load current of 'case (load L ₁₁ to be changed to' the load L ₁₁ load L ₁₁ is the case where the load L ₁₁ greater than It is assumed to change. in), with the change from the load L ₁₁ to the load L ₁₁ ', in the electrical equipment (in this example the upper doing the feeding to the load L _11, toward the upper from the lower , Consider whether updating of breaker B ₁₁ , frame F ₁₁ , breaker B _1i , frame F _1i , first main trunk cable 61 (W1), breaker B _1o , frame F _1o ) should be performed, as necessary Electrical work such as replacement should be done.

(It is to be noted that the above-mentioned examination may be performed for the conductor between the breaker B ₁₁ and the breaker B _1i , but it is not necessary in practice.)

Conventionally, electrical equipment of upper that performs power supply to the load L ₁₁ is, whether adaptable to the load L ₁₁ ', on the basis of an electric equipment table listed in builts buildings, by manual calculation I was working to confirm. The problem that such work requires much labor and time has been described in the section "Problems to be solved by the invention".

  Another object of the present invention is to realize information display of electrical equipment by BIM (Building Information Model).

  Therefore, in the electrical facility management system according to the present invention, a three-dimensional CAD data of a building, a database of electrical facilities in the building, a database of loads used in connection with the building are created, and these data and database are based. As a result, it is determined whether to replace the electrical equipment accompanying a change in load, and information display of the electrical equipment by BIM (Building Information Model) is realized. FIG. 4 is a conceptual view of data stored in the external information device 20 of the computer capable of executing the electric facility management system. As illustrated, in the external information device 20, a building three-dimensional CAD data 23, an electric facility database 24, and a load database 25 are recorded, and the CPU 11 etc. are referred to as needed. By doing this, the electric facility management system according to the present invention is realized.

  As the building three-dimensional CAD data 23, any one capable of realizing a conventionally known BIM (building information model) can be used. FIG. 5 is a view showing an example of the data structure of the electrical installation database 24. As shown in FIG. The electrical equipment database 24 stores data of items such as “electrical equipment name data”, “specific data of electrical equipment”, “position data of electrical equipment”, and “installation status data of electrical equipment”.

  Here, as the electrical equipment handled by the electrical equipment database 24, it is more preferable to cover all the electrical equipment in the building, but the data on the power receiving and transforming equipment, the data on the switchboard, and the data on the distribution board And data on a cable between the switchboard and the switchboard may be included at least.

  "Electric equipment name data" is a field for recording the name, type, etc. of the target electric equipment, and it is unique to be able to identify which electric equipment in the building.

  Also, “specific data of the electrical installation” is a column for storing data regarding the specifications of the target electrical installation. In this field, the item, the number of items, and the like vary depending on the type of the target electrical installation. Moreover, it is arbitrary what kind of data is included as specification data.

  An example of “electrical equipment name data” and “specific data of electrical equipment” will be described with reference to FIGS. 6 to 8. In FIG. 6, “breaker” is used as “electric equipment name data”, and “amperage trip value” of the breaker is used as “specific data of electric equipment”. Such data configuration is merely an example, and can take any form. The data in FIG. 6 conforms to the block diagram in FIG.

  In FIG. 7, “frame” is used as “electric equipment name data”, and “frame ampere frame value” is used as “specific data of electric equipment”. Such data configuration is merely an example, and can take any form. The data of FIG. 7 also conforms to the block diagram of FIG.

  In FIG. 7, “cable” is used as “electric equipment name data”, “cable type” as “specific data of electric equipment”, “electric system” (single-phase three-wire system, three-phase three-wire system) Etc.), "allowable current" has been made into data. Such data configuration is merely an example, and can take any form. The data of FIG. 7 also conforms to the block diagram of FIG.

  Referring back to FIG. 5, “position data of electrical equipment” is position coordinate information of the installation position of the target electrical equipment, and by associating the position coordinate information with the three-dimensional CAD data 23 of the building, , To realize information display of electrical equipment by BIM (Building Information Model).

  In addition, “installation condition data of electrical equipment” is a field for storing under which environment the target electrical equipment is installed.

  Next, data of the load database 25 will be described. FIG. 9 is a view showing an example of the data structure of the load database 25. As shown in FIG. As illustrated, the load database 25 stores data of items such as “load name”, “load type”, “load current”, “power consumption”, “power factor”, “apparent power (VA)” and the like. Keep it.

  The “load name” is a field for recording the name of the target load, etc., and is unique so that it can be identified which electrical installation is in the building. The “load type” is a field in which the type of target load (lighting, air conditioner, elevator, or the like) is stored. Also, “load current” is a column for storing the load current of the target load. Also, “power consumption” is a field for storing the power consumption of the target load. Also, “power factor” is a column for storing the power factor of the target load. Also, "apparent power (VA)" is a column for storing apparent power (VA) of the target load.

  The load has different units of power depending on the type, but in particular, the load database 25 stores data of each item (unit) of "power consumption", "power factor" and "apparent power (VA)". The comparison of loads between different units can be intuitively grasped.

Next, various determination processes by the electric facility management system according to the present invention as described above will be described. First, in block diagram in FIG. 3, the load L ₁₁ load L ₁₁ '(load current A _11') as an example the case of changing the, unnecessary or necessary to replace the breaker frame in the first distribution board 71 The process of determining the presence or absence will be described.
