Description

  INDUSTRIAL APPLICABILITY According to the present invention, the specification of a distribution board in which various internal devices (internal devices) such as a main breaker and a branch breaker are arranged inside a box having a door can be efficiently determined using a computer. The present invention relates to a distribution board specification creation system.

  As shown in FIG. 1, the distribution board is obtained by attaching an internal device 3 such as a breaker inside a box 1 having a door 2. The inner unit 3 is mounted on a mounting base 4 mounted at a position slightly higher than the back surface of the box 1, and the upper surface of the inner unit 3 is generally covered with an inner door 5 in consideration of safety. is there. In addition, other devices may be mounted on the back surface of the door 2 as necessary.

  In the present specification, the internal unit 3 disposed on the mounting base 4 is referred to as an internal unit 6, and the other equipment mounted on the back surface of the door 2 is referred to as a door option 7.

  When creating such a new distribution board specification, first select the size and type of the box 1 in consideration of the installation location, etc., and then select the internal unit 6 and the door option 7. Is the normal procedure. However, as shown in FIG. 1, the box depth that is the depth of the box 1 is A, the inner unit height that is the height of the inner unit 6 is B, and the option height that is the height of the door option 7 If C is C, depending on the type of door option 7, B + C may be larger than A, and the internal unit 6 and the door option 7 may interfere with each other and cannot be stored.

  When such a problem occurs, it is normal to reselect another box 1 having a larger box depth A so that the selected internal unit 6 and door option 7 can be accommodated. However, the box 1 is often selected based on the installation environment, and it is desirable to avoid changing its size as much as possible. In addition, since the change of the box 1 also affects the production cost, it is actually desirable to avoid it as much as possible.

  In such a case, it is preferable to reselect the internal unit 6 and the door option 7 without changing the selection of the box 1. However, when storing multiple internal units 6 and multiple door options 7 in a single box 1, customers and operators (designers) select and arrange the most suitable one while judging the presence or absence of mutual interference. The work to do was not easy and took a lot of time and effort.

  The applicant's patent document 1 proposes a distribution board design support system, which mainly relates to the planar arrangement of the inner unit 3 inside the box 1 and is a problem in the present invention. There is no description on how to avoid interference between the internal unit 6 and the door option 7.

A flow sheet according to the invention of claim 3. It is explanatory drawing of invention of Claim 4. A flow sheet according to a fourth aspect of the present invention. It is the flow sheet which integrated this invention.

  Embodiments of the present invention will be described in detail below. First, a first embodiment corresponding to Claim 1 will be described. As shown in FIG. 2, a server 10 for carrying out the present invention is a general server including a calculation unit 11, a storage unit 12, an input unit 13, and an output unit 14. It is connected to a customer or operator terminal 16 via a communication means 15 such as the Internet. This hardware configuration is not unique to the present invention, and any known device may be used as appropriate as the above-described means.

The storage means 12 stores at least a box database 20, an internal unit database 30, and a door option database 40. As shown in Table 1, the box database 20 is provided with data of the box depth and the optimum height of the internal unit attached to the box, and Table 1 shows Box 1 to Box 6. Yes. This is to simplify the explanation, and it goes without saying that the data of a very large number of boxes is actually aggregated. The box depth is the dimension A shown in FIG. 1, that is, the distance from the back of the box to the door. The optimal internal unit height is the most preferable internal unit height dimension B for the box, which is a unique value set in advance based on the ease of wiring and the operation of the internal unit after placement. is there. In this embodiment, the box depth is set at intervals of 50 mm, but may be set at shorter intervals.

  As shown in Table 2, the internal unit database 30 is provided with data on a plurality of box depths to which the internal unit can be attached and the manufacturable height of the internal unit. 2, the internal units A to H are shown. The mountable box depth is indicated as the corresponding box depth in Table 2. The manufacturable height is a height at which the dimension B of the inner device height can be changed by changing the height of raising the bottom of the inner device unit, and is set at intervals of 50 mm in this embodiment. Since the internal unit A is small, the manufacturable height is 100 to 300 mm. However, since the internal unit H is large, the manufacturable height is only 300 mm, and the box depth is 400 mm. Can only be installed.

  The door option database 40 includes data of option height for each door option, and Table 3 shows door options 1 to 6. The option height is dimension C in FIG. The door option is, for example, a display lamp or an electric energy meter.

  The calculation means 11 and the input means 13 will be described below with reference to the flow sheet of FIG. First, a box, an internal unit, and a door option are sequentially selected by the input means 13 (S1). As for the selection of a box, a box that matches the conditions is selected when a case size or application (outdoor / indoor use) or the like is input. However, a box model number may be directly input. To select the internal unit, enter the capacity of the installed main breaker, the capacity of the branch breaker, the number of branches, etc., and the internal unit that matches the conditions will be selected. You may enter. A plurality of internal unit and door options may be selected. The order of selection is free.

  When a box, an internal unit, and a door option are selected, the calculation means 11 accesses the respective databases in the storage means 12 and reads data corresponding to the selected model number symbol, so that the corresponding box of the selected internal unit is selected. A first determination step (S2) for determining whether the depth of the selected box is included in the depth is executed. When a plurality of internal units are selected, this determination is performed for each.

  If it is not included, an error display (S3) is performed so that the internal unit is selected again. If it is included, the optimum inner height of the box is determined (S4). For example, as shown in Table 4, when the box 4 and the internal units A and D are selected, 300 mm which is the optimal internal unit height of the box 4 is included in the manufacturable height of the internal units A and D. Therefore, the optimum inner height of the box is determined to be 300 mm.

  Next, it is determined whether or not the optimum height of the internal unit determined in S4 is included in the manufacturable height of the internal unit (S5), and if it is not included, an error display (S6) is performed. .

  If it is included, a second determination step is executed to determine whether or not the option height of the selected door option is included in the difference between the box depth and the optimum inner device height (S7). If it is included, there is no possibility of interference, so normal display (S8) is performed, and the selected box, internal unit, and door option are displayed on the output means 14. As a result, the specifications of the distribution board are determined, and thereafter, the process shifts to normal production.

  If the option height of the door option is not included in the difference between the box depth and the optimum inner unit height, it means that the inner unit and the door option interfere with each other as they are. In this case, a correction step (S9) for correcting the inner device height to be lower within the range of the manufacturable height of the selected inner device unit is executed. Thereby, it is possible to determine the specifications of the distribution board in which the internal unit and the door option do not interfere with each other.

  Specifically, when door option 1 is selected as shown in Table 4, the option height of the door option is 100 mm, which matches the difference between the box depth of 400 mm and the optimum inner device height of 300 mm. Then, normal display (S10) is performed and the process ends.

  However, when door option 3 is selected, the option height of the door option is 180 mm, which exceeds 100 mm, which is the difference between the box depth of 400 mm and the optimum inner device height of 300 mm. The height of A and D is corrected to 200 mm which is the height that can be produced. Then, the above difference becomes 200 mm of 400 mm-200 mm, and an optional height of 180 mm can be stored. However, if the door option 6 is selected, the option height of the door option is 300 mm, the minimum height of the internal unit D that can be manufactured is 150 mm, and the difference is 250 mm. Is the limit. In such a case, since it is impossible to avoid interference, an error display (S11) is performed.

  When this error display (S11) appears, it is necessary to go back to the beginning and make a selection again. For example, it is necessary to reselect a box having a larger box depth or reselect an internal unit and a door option. There is. A suitable box may be automatically selected.

  Next, a second embodiment corresponding to claim 2 will be described. In the first embodiment, only the interference in the depth direction of the box is considered, but the wiring direction of the box and the internal unit may be limited, and the specification is determined in consideration of this. It is preferable. For example, in an outdoor box with a roof, it is difficult to make the wiring direction upward. Also, the wiring direction of the internal unit may be limited depending on the arrangement of the main breaker and the like. In such a case, as shown in FIG. 4, it is necessary to match the wiring direction of the box with the wiring direction of the internal unit. The wiring direction includes an incoming line direction and an outgoing line direction.

  In the second embodiment, the steps described below are added to the first stage of the first embodiment. For this reason, as shown in Table 5, input / output line direction data that can be respectively corresponded to the box database 20 and the internal unit database 30 are added. The upper direction in Table 5 means that the incoming line direction and the outgoing line direction are both upward, and the others are the same. Note that data such as the capacity of the installed main breaker, the capacity of the branch breaker, and the number of branches are added to the internal unit database 30. The computing means has a function of comparing the input / output line direction of the selected internal unit with the input / output line direction of the selected box, and replacing it with a matching internal unit if it does not match.

  The second embodiment will be described with reference to the flow sheet of FIG. 5. First, the wiring direction is designated (SS1). Then, the computing means accesses the box database 20 and the internal unit database 30, and selects a box and an internal unit that can correspond to the designated wiring direction (SS2). The specification of the first wiring direction may be omitted, and an internal unit that matches the wiring direction of the selected box may be selected as a reference.

  Next, it is determined whether or not the wiring direction that can be handled by the selected internal unit matches the wiring direction of the box (SS3). If they do not match, an error is displayed (SS4). If they match, it is determined whether or not the selected incoming / outgoing line direction matches the incoming / outgoing line direction that can be handled by the internal unit (SS5).

  If they do not match, the arithmetic means performs correction to replace the internal unit with the same input / output line direction (SS7), but in this case, the internal unit database 30 is accessed and not only the wiring direction. The capacity of the main breaker, the capacity of the branch breaker, the number of branches, etc. are changed to the same internal unit. If there is something that matches such a condition, normal display (SS6) is performed, and if there is no matching condition, error display (SS8) is performed.

  Table 6 shows specific examples. In the example of Table 6, the wiring direction that can be handled by the selected box 2 is only “lower and lower”, and the wiring direction that can be handled by the selected internal unit C is only “up and down”. Therefore, the internal unit A including “lower and lower” as a compatible wiring direction is replaced.

Next, a third embodiment corresponding to claim 3 will be described. The third embodiment relates to a unit option that can be arranged on the internal unit. The unit option is an optional device such as a flashing circuit, a time switch, a relay, etc., and is arranged in an option space provided on the internal unit unlike the door option.

  FIG. 6 is a diagram showing an outline thereof, and an option space 6 a for a unit option is set in advance on the internal unit 6. Since the size of the option space 6a varies depending on the internal unit 6, data on the presence / absence of the optional space and the number of unit options that can be attached are added to the internal unit database as shown in Table 7.

  Further, as shown in Table 8, a unit option database 50 in which priority order and occupied space data are collected for each unit option is added to the storage device of the server. The unit option database 50 includes data of the independent units 1 to 7, and this indicates that when the selected unit option cannot be installed in the option space 6 a on the internal unit 6, the internal unit 6 The unit is arranged as shown in FIG. 6 as an independent unit.

  The third embodiment will be described with reference to the flow sheet of FIG. 7. First, when selecting an internal unit (SS 11) and selecting a unit option (SS 12), the computing means is connected to the internal unit database 30. The unit option database 50 is accessed to determine whether or not the selected unit option can be installed in the option space of the selected internal unit (SS13).

  If it can be installed, there is no problem, but if it is determined that the number of installable limits is exceeded (SS14), the units are arranged according to the priority order of the unit options (SS15), but the option space 6a becomes full. In such a case, the selected unit option is unavoidably replaced with the independent unit 6b (SS16), and is arranged adjacent to the internal unit 6 as shown in FIG. 6, and is normally displayed (SS17).

  Each of the steps described above is preferably executed following the determination of the wiring direction described in the second embodiment. Table 9 shows specific examples.

  Next, a fourth embodiment corresponding to claim 4 will be described. The fourth embodiment is applied when an internal unit and a unit option are selected in the third embodiment. In other words, the main breaker of the selected internal unit may be replaced with one provided with an accessory such as a terminal block, and when the terminal block overlaps with the unit option placement space as shown in FIG. Unit options may not be arranged.

  Therefore, as shown in the flow sheet of FIG. 9, when the main breaker is replaced with one provided with an accessory device (SS20), the calculation means determines whether the accessory device interferes with the arrangement space of the unit option. When there is no interference, the normal display (SS22) is performed. When it is determined that there is interference, the main circuit breaker is replaced with a main breaker equipped with an accessory on the opposite side (SS23). As a result, interference between the accessory device and the unit option can be avoided.

  This replacement needs to be performed with a main breaker having the same current capacity and the same type of breaker and the attached device on the opposite side. Therefore, as shown in Table 10, for each internal unit, create a database with the presence / absence of the space next to the main breaker, the number of poles of the terminal block that can be attached to that space, and the pop-out allowable direction data, and store it in the storage means Let me. Further, as shown in Table 11, a master breaker database 60 having data on the jumping direction of the accessory device is created for each main breaker and stored in the storage means. Table 12 shows an example of the execution result.

  As described above, the present invention is based on the contents of claim 1, but the wiring direction is unified according to claim 2, unit options are added according to claim 3, and claim 4 is described. It can be operated as a system in which the addition of additional devices is appropriately combined. FIG. 10 is a flow sheet in which these are integrated. In this example, procedures for unifying the wiring direction, adding unit options, and correcting the height of the internal unit are adopted. As described above, according to the system of the present invention, it is possible for a customer or an operator to easily create an optimal distribution board specification while avoiding mutual interference.
