[0020]
And a change arises in a circuit, for example, when a circuit enlarges, the structure of the cabinet case 1000 is changed.
Specifically, as shown in FIGS. 2 and 3, members for coupling the right unit 10 and the left unit 20 (a base coupling member 50 having a width a, a rear coupling member 60, and a ceiling coupling member 70). As shown in FIG. 4, the base part coupling member 50 ′, the back surface coupling member 60 ′, and the ceiling part coupling member 70 ′ having a width as wide as b are replaced.
[0021]
As shown in FIG. 5 (b), the base portion coupling member 50 shown in FIG. 5 (a) is removed by loosening the fastening by the screw portion 51, and has a wide width as shown in FIG. 4 and FIG. 5 (c). Base part coupling member 50 'is inserted. Whereas the base portion coupling member 50 is a plate body, the base portion coupling member 50 ′ includes a pedestal portion 50a ′ and a plate body 50b ′ as shown in FIGS. 5 (c) and 5 (d). In a state where the plate body 50b ′ is raised by the portion 50a ′ so that the plate body 50b ′ has the same height as the right base portion 11 and the left base portion 21, and the plate body 50b ′ is stretched over the right base portion 11 and the left base portion 21. The screw part 51 is screwed into the nut part 11a fixed to the right base part 11 and the nut part 12a fixed to the left base part 11, and fastened and fixed.
[0022]
As shown in FIG. 6 (b), the back surface coupling member 60 shown in FIG. 6 (a) is removed by loosening the fastening by the screw portion 61, and has a wide width as shown in FIG. 4 and FIG. 6 (c).

[0023]
As shown in FIG. 7 (b), the ceiling portion coupling member 70 shown in FIG. 7 (a) is removed by loosening the fastening by the screw portion 71, and has a wide width as shown in FIG. 4 and FIG. 7 (c). The ceiling part coupling member 70 ′ is spanned over the right ceiling part 13 and the left ceiling part 23, and the nut part 13 a fixed to the right ceiling part 13 and the nut part 23 a fixed to the left ceiling part 23, respectively. The screw portion 71 is screwed and fastened.
[0024]
The cabinet case after completion of such expansion is assembled in a shape as shown in FIGS.
The screw portions 51, 61, 71 are not limited to the numbers and positions shown in FIGS. 9 and 10, and various numbers and positions can be selected in accordance with the actual state (see FIG. 9 and 10, the screw portions 51, 61, and 71 are not illustrated in detail, as the simplified illustrations allow the number and position to be understood.
[0025]
The cabinet case 1000 ′ thus expanded is shown in FIG.
The right unit 10, the central unit 80, the left unit 20, and the front units (front panel or door) 90 and 100, which are three types of basic units, are combined. Here, the area of the opening entrance is increased due to the addition of the central unit 80, but this is dealt with by increasing the area of the front face 90 as shown in FIG.
[0026]
The right unit 10 has a right base portion 11, a right back surface portion 12, a right ceiling portion 13, and a right side surface portion 14 integrated by a frame formed of an angle-shaped aggregate (not shown) as described above. Is open (see FIG. 9).
The left unit 20, the left base part 21, the left back part 22, the left ceiling part 23, and the left side part 24 are integrated by a frame formed of an angled aggregate (not shown) as described above. Is open (see FIG. 9).
[0027]
The central unit 80 shares the frame of the angled aggregate of the right unit 10 and the left unit 20, and the base unit coupling member 50 ′ and the back coupling member 60 ′ and the ceiling coupling member 70 ′ are integrated into both sides. The surface and the entire surface are open.
[0028]
The right unit 10, the central unit 80, and the left unit 20 all have the same vertical and depth dimensions, but the width is designed to take a plurality of lengths depending on the number of circuits added by the central unit. The three units are not the same width. The right unit 10 and the left unit 20 have the same vertical, width, and depth dimensions.
[0029]
A simple structure as shown in FIG. 11 is used for attaching and detaching the front portions 90 and 100.
As shown in FIG. 11B, the shaft 130 is attached to the front surface side hinge 110 attached to the front surface portion 30 (or the front surface portion 90) and the right side surface portion side hinge 120 attached to the right side surface portion 14. Is inserted, and the shaft 130 is pivotally supported by retaining the upper and lower ends of the shaft 130 with snap pins (pine needle pins) 140. Therefore, even if the front surface portions 90 and 100 are doors, they can be easily attached and detached.
[0030]
The door can be replaced in both the left and right directions (the left door is replaced when the power side is added, and the right door is replaced when the customer side is added), and the ceiling and back are also integrated. It can be adapted to the installation conditions on site or the expansion structure.
The cabinet case 1000 ′ after expansion is configured in this way.
[0031]
Next, the combinational circuit accommodated in the cabinet cases 1000 and 1000 ′ will be schematically described. FIG. 12 is an explanatory diagram for explaining an example of combination of combinational circuits, and FIG. 13 is an explanatory diagram for explaining an example in which the combinational circuit is mounted on a cabinet case.
[0032]
When one switch is defined as one circuit, the combinational circuit includes three circuits (FIG. 12A), four circuits (FIG. 12B), and five circuits (FIG. c)), 6 circuits (FIG. 12D), 7 circuits (FIG. 12E), 8 circuits (FIG. 12F), and 9 circuits (FIG. 12G) are changed. Can do. Such a change in circuit configuration is due to customer demands such as changes in power demand and automation. For example, description will be made assuming that the circuit is changed from a simple three-circuit switch (FIG. 12 (a)) to a six-circuit configuration as shown in FIG. 12 (d).
[0033]
In this case, it is assumed that the cabinet case 1000 as shown in FIG. 1 is changed to the cabinet case 1000 ′ as shown in FIG. 8 to form a combination circuit of six circuits as shown in FIG.
In this six-circuit configuration, a power supply device built-in switch 300, a three-circuit switch 400, a mold discon 500, and a UGS (Ground Switcher Gas Switch) 600 are connected to the mold bus 200. A manual mechanism 700 is connected to the power supply built-in switch 300, and a manual mechanism 700 and an automatic mechanism 800 are connected to the three-circuit switch 400, respectively.
A mold bus 200 is connected to one end of each switch (breaker), and a CVT cable (not shown) is connected to the power company side and the customer side at the other end.
[0034]
Although not shown, the external connection terminal has a structure that can be connected to a molded diescon direct connection type terminal connection part. Normally, the power company uses a molded diescon directly connected termination connection, and the consumer does not have a voltage detection function but is cheaper than the molded diescon directly connected termination connection. Part is used.
The combinational circuit is like this.
[0035]
Even if it is necessary to change (mainly enlarge) the combinational circuit in this way, the cabinet case 1000 can be added and immediately changed to the cabinet case 1000 ′ having a large accommodation area, so a new cabinet case needs to be purchased. And replacement costs can be minimized.
[0036]
In addition, after designing the combinational circuit according to the customer's request, it is possible to easily adopt the optimum cabinet case, so that the delivery time can be shortened.
In this case, if the left side unit, the right side unit, and a plurality of sets of base part coupling members, back surface coupling members, and ceiling part coupling members having different widths are stocked, a cabinet case is immediately manufactured. This also helps to shorten the delivery time.
[0037]
【The invention's effect】
In general, according to the present invention, it is possible to provide a cabinet case in which the accommodation volume can be easily changed corresponding to an internal circuit, and a cabinet using the cabinet case.
