た配電ユニット３を取付けるのみでよい。According to the present invention, since the horizontal circuit breakers are arranged in the height direction, the horizontal width of the switchboard surface 70 is shortened, and the busbar 24 and the circuit breaker 9 are detached by the contactor without using the connecting conductor. By freely connecting directly, the depth of the switchboard can be shortened. Further, since the power distribution unit 3 can be separated from the bus bar unit 2 and the devices (the circuit breaker 9 and the bus bar 24) inside thereof can also be separated, the operation after the installation of the switchboard can be made extremely smooth. For example, it may be desired to change the circuit breaker capacity or the like due to an increase in load, but since the power distribution unit 3 can be removed together with its internal equipment, it can be changed while the other power distribution unit 3 and the bus bar unit 2 are in operation. It is possible. In addition, since it is unitized, it is only necessary to mount the power distribution unit 3 accommodating the equipment of another capacity.

It is possible to change the equipment and busbar while the power is on. In this respect, the bus bar 24 and the circuit breaker 9
In the case of the conventional method in which and are connected by a connection conductor, the connection conductor is often not designed to sufficiently withstand the current flowing through the circuit breaker after the change. It was necessary to stop the energization of the bus bar.

ことが重要である。FIG. 9 shows the connection between the circuit breaker 9 and the bus bar 24 with the insulated conductor 50 removed from the cross section of FIG. Further, FIG. 11 shows the appearance of the connection state between the circuit breaker 9 and the bus bar 24. These contacts 31 are detachably directly connected to the double bus bar 25 without using a connecting conductor. A large current flows from the buses 24 and 25 to the load cable 61 via the circuit breaker 9 in a normal operating state or in the event of an accident. Therefore, in order to reduce the size of the switchboard, it is important to suppress heat generation from these devices or conductors and quickly dissipate the heat generation.

熱放散が円滑に行える。According to the present invention, the heat generation from the conductor can be reduced and the heat can be smoothly dissipated by the detachable direct connection and the double busbar. That is, the current in the switchboard is shunted to flow through the circuit breaker 9 from the busbar 24 via the plurality of connecting pieces 26 and the busbar 25, and the amount of heat generated is small and the surface area is increased because the current in each shunt is small. This allows for smooth heat dissipation.

The load-side contact piece 32 is arranged at a position in contact with each load-side contact piece 34 of the circuit breaker 9. One end of each contact piece 32 is connected to the vertical conductor 51. The vertical conductors 51 of each phase are arranged at predetermined intervals in the moving direction of the circuit breaker,
In other words, it is placed in the depth to reduce the width of the switchboard.
When the three-phase vertical conductor 51 and the three-phase load contact piece 32 are brought into contact with each other, the load contact pieces 32 of at least two phases are bent so as to reduce the inclination angle inclined in the circuit breaker direction. Although 32 have different heights, they are drawn to the same drawing position. The lower end of the vertical conductor 51 extends into the load cable chamber 60, is connected to the load cable 61, and is integrally resin-molded.

んど問題とならない。According to the present invention, it may be considered that inspection and repair in the power distribution unit becomes difficult as a result of the volume being very small. However, the breaker unit should be completely pulled out from the power distribution unit. This is less of a problem since it is possible and the power distribution unit itself can be separated from the busbar.

し、奥行き寸法を縮小した。従って、配電盤の容積を大
幅に縮小できた。Since the switchboard of the present invention is constructed as described above, it has the following actions and effects. The circuit breaker 9 has a circuit breaker arranged horizontally and three layers stacked in the height direction to reduce the width direction of the circuit breaker and the switchboard. As a result, the circuit breaker becomes longer in the depth direction, but the power source side contactor is detachably arranged directly orthogonal to the bus bar 25 to omit the branch conductor and the insulating mold disconnection section in the conventional switchboard, and the depth dimension Was reduced. Therefore, the volume of the switchboard could be significantly reduced.

Since the width of the switchboard can be reduced, the volume of the switchboard can be further reduced. By the way, according to the present invention, the height is the same as the conventional 2.3 meters, but the depth is 0.9 meters,
The width can be set to 0.3 meters, and the volume can be reduced to ⅕ in comparison with the conventional one.

The load cable 61 is connected to one end of the insulated conductor 50, and the load side fixed contactor 34 is attached to the other end. The load side fixed contactor 34 electrically contacts and separates from the load contactor piece 32. As a result, the load side fixed contactor 34 and the load contactor piece 32 can be connected in the shortest distance, so that the electric resistance is small and the heat generated can be reduced. Also, as shown in FIG. 9, the load cable chamber 61 has two
In the present invention, since the load cable chamber 61 can be arranged adjacent to the compartment 41, there is an advantage that the distribution board can be further downsized, for example, the height can be reduced.

Part of it may be displaced in the depth direction. Further, the bus bar and the circuit breaker may not be detachably directly connected but may be connected by a connection conductor having a sufficiently short capacity.

点がある。According to the present invention, since the load side fixed contact 34 and the load contact piece 32 can be connected in the shortest distance, the electric resistance is small and the heat generated can be reduced. Further, since the load cable chamber 61 can be arranged adjacent to the compartment 41, there is an advantage that the distribution board can be further downsized, for example, the height can be reduced.
