The first horizontal member 1 and the second horizontal member 3 are formed with bent pieces 1a and 3a bent at right angles to their peripheral edges (hereinafter, similar portions are referred to as bent pieces).

The detailed structure and assembling process of the switchboard of this embodiment having the above-mentioned compartments will be described below. Step 1. As shown in FIGS. 6 and 7, a pair of vertical members 5 are attached to the respective intermediate portions in the front-rear direction of the left and right edges of a rectangular base 4 made of an iron plate and having a space between it and the floor. That is, the vertical member 5 is a vertically long rectangular iron plate having a bent piece on the periphery thereof, and the bent piece 5a at the lower edge thereof is fixed to the base 4 with a screw. This allows the base 4 to be viewed from the side.
And the vertical member 5 jointly look like an inverted T-shape.

Step 2. Next, the pair of vertical members 5 are connected to each other at the top. That is, the bent pieces at the left and right ends of the upper connecting plate 6, the intermediate connecting plate 7, and the lower connecting plate 8 made of iron plates each having a bent piece on the periphery are fixed to the pair of vertical members 5 with screws. In addition, in FIG. 1 and FIGS. 7 to 11 below, illustration of built-in parts is omitted for easy understanding of the assembling method.

Step 3. As shown in FIGS. 4, 5 and 8, a plurality of insulating rods 9 are attached to the upper connecting plate 6 and the intermediate connecting plate 7 with screws, and a bus bar 10 made of a thick copper strip for three phases is formed on the insulating rod 9. Attach the disconnector 11. Since this attachment work can be performed in a state where almost no member that obstructs the work is attached, the bus bar 10 and the like are heavy and long, but can be attached safely and easily. In addition,
As shown in FIG. 6, the vertical member 5 is formed with a hole 5b for extending the bus bar 10 in a power supply panel provided in parallel with the generator panel.

Step 4. As shown in FIGS. 7 and 9,

Although the work of mounting the circuit breaker C, the copper plate 14, etc. is heavy, these work can be performed safely and easily for the same reason as the work of mounting the bus bar 10 described above.

Step 6. As shown in FIGS. 1 and 9,
The left and right ends of the vertical surface of the first horizontal member 1 of the built-in unit of the generator control section A are attached to the vertical bending pieces 5c of the vertical member 5 with screws. As a result of attaching these, the first lateral member 1
The vertical surface of the second horizontal member 3, the vertical surface of the second lateral member 3 and the back surface of the circuit breaker C form a wall that separates the front part from the middle part and the rear part of the switchboard. Step 7. As shown in FIG. 1, FIG. 8 and FIG. 10, four vertically long rectangular side plates 15 are attached to the front and rear of the vertical member 5 so as to form one row each on the left and right. That is, the side plate 15

Fix it. Note that FIG. 10 shows a state in which the left side plate 15 is attached. The side plate 15 and the vertical member 5 attached in this manner form a convex portion in which the vertical member 5 projects outward, as shown in FIG. By arranging so as to form the convex portion in this way, even if the decorative plate 36 shown by the chain line is attached to the side surface, the head of the screw does not get in the way. Further, the control wiring or the like can be arranged in the space formed by the decorative plate 36 and the side plate 15. Furthermore, it is possible to cover the side part of the switchboard having a large area with two side plates with a relatively small width and one vertical member, which can be easily pressed by each piece, and connect them using the bent pieces. The strength can be increased by combining them.

Step 8. As shown in FIGS. 8 and 10, the bent pieces 1a, 3a at the left and right ends of the first lateral member 1 and the second lateral member 3 are fixed to the left and right side plates 15 at the front with screws. Step 9. As shown in FIGS. 10 and 11, an upper front bar 16, an intermediate front bar 17, a U-shaped upper rear cover 18, and an intermediate rear bar 19 each made of an iron plate having a bent piece on the periphery thereof.
Are attached to the front and rear left and right side plates 15 with screws by using the bent pieces at both the left and right ends. Note that FIG.
1 shows a state in which the left side plate is removed. Step 10. As shown in FIGS. 2 and 4, in the front portion of the switchboard, the hinge-type door 2 of the generator control section A, the hinge-type door 20 of the common section B, and the fitting-type cover 21 of the circuit breaker C are provided.

It is fixed to the rear crosspiece 19 through the intermediate portion. In addition, the current transformer 25 is connected to the lower connecting plate 8 or the connecting plate 23 so that the connecting plate 23 penetrates.
Fixed to. Since the upper part of the rear space of this embodiment is an empty space, the input cable can be introduced from the rear upper part. Step 12. As shown in FIGS. 3, 5 and 8, a vertical separator 26 that separates the generator control section A for each generator and also separates between the circuit breaker bodies is provided as the first horizontal member 1 and the second horizontal member. Install it with 3 and screws.
Further, a separator 27 that separates the vicinity of the terminal portion of the circuit breaker C between the circuit breakers is attached with a screw between the intermediate connecting plate 7 and the lower connecting plate 8, and a separator 37 that separates the connecting plate 23 for each circuit breaker is provided.

The present invention is carried out in the form described above, and has the following effects. It is possible to easily and freely attach the built-in component to the horizontal member attached to the vertical member separately in the front portion of the vertical member, the width portion of the vertical member, and the rear portion of the vertical member. Further, by using the horizontal member having the vertical surface, it is possible to easily separate the space between the front portion of the vertical member, the width portion of the vertical member, and the rear portion of the vertical member. Further, many built-in parts can be easily attached in a state where the side plate of the switchboard is not attached.

The strength of the switchboard can be easily ensured by using the transverse member which is bent at a right angle and has a vertical surface and a horizontal surface. In addition, since various parts can be attached or wired to the lateral member in advance, the switchboard can be easily assembled in a short time. Further, the vertical surface of this lateral member forms a wall, and can also serve as a separator that divides the switchboard in the front-rear direction. Even if a thin plate-like member having bent pieces formed around it is used as the vertical member or the horizontal member, it is possible to configure a switchboard having high strength and light weight.

By arranging the vertical member and the side plate so as to form a convex portion, even when a decorative plate covering the vertical member and the side plate is attached or the distribution boards are arranged in close contact with each other. , Parts can be screwed inside the side plates. Also, an electric wire can be laid on the outside of the side plate. By adopting the above-mentioned switchboard for the generator panel of a ship equipped with multiple generators, it is possible to unitize the parts for controlling and monitoring the generator, which has a large number of parts and many wires between parts. Assembling time is shortened. Also, in the above generator panel, by disposing the bus bar in the middle part of the switchboard, the bus bar and other units can be easily attached, and the bus bar that is the charging part can be easily separated, resulting in an electric shock accident. Can be prevented.
