る。FIG. 1 shows the arrangement of equipment inside the load unit 11 and the busbar unit 2 which are the main units of the power distribution unit 3, and the power distribution unit 3 and the busbar unit 2 can be separated from each other as described above. It is said that Inside the busbar unit 2, busbars 24 for three phases extending in the horizontal direction are provided.
Is installed.

必要があり、母線の通電を停止する必要があった。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. The depth of the switchboard can be shortened by freely connecting directly. 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. Further, the busbar 24 and the circuit breaker 9 are detachably directly connected by a contactor without using a connecting conductor, so that when it is desired to change the circuit breaker capacity or the like due to an increase in load, the circuit breaker or the busbar in another unit can be changed. It is possible to change while keeping the power on.
In this respect, in the case of the conventional method in which the bus bar 24 and the circuit breaker 9 are connected by the connection conductor, the connection conductor is often not set to sufficiently withstand the current flowing through the circuit breaker after the change. At the same time, it was necessary to change the connection conductor in the energized state, and to stop energizing the busbar.

により熱放散が円滑に行える。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. 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 vertical conductors 51 of each phase are arranged at predetermined intervals in the moving direction of the circuit breaker, that is, in the depth to reduce the width dimension 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 piece 32 of at least two phases is bent so as to reduce the inclination angle inclined in the circuit breaker direction,
The load contact pieces 32 have different heights, but are drawn to the same drawing position. The lower end of the vertical conductor 51 has a load cable chamber 60.
And is connected to the load cable 61 and is integrally resin-molded.

を１／５とすることができる。The switchboard of the present invention is constructed as described above and 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,
Although the circuit breaker becomes longer in the depth direction, the power source side contactor is detachably arranged directly orthogonal to the bus bar 25 to omit the branch conductor and the insulation mold disconnection section in the conventional switchboard, and the depth dimension has been reduced. .. Therefore, the volume of the switchboard could be significantly reduced. Further, in the insulated conductor 50, since the three-phase vertical conductors and the load contact pieces are arranged at a predetermined interval in the moving direction of the circuit breaker, the width dimension becomes narrower than the depth dimension,
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 2.3 meters, which is the same as the conventional one, but the depth can be 0.9 meters and the width can be 0.3 meters, and the volume can be reduced to 1/5 at the conventional cost.

電盤組合せ設計が容易化されている。Further, according to the present invention, the power source side contactor of the circuit breaker 9 is detachably directly connected to the double busbar. Therefore, the current from the bus bar 24 flows to the circuit breaker 9 via the shunt section and the connecting bus bar, and the generated heat is reduced, which greatly contributes to the volume reduction of the switchboard. In other words, if the same current as before is applied to each branch of the double bus, it is possible to double the circuit breaker current carrying capacity. It means that it is easy to unitize even the capacity. Also,
According to the present invention, the power distribution board is composed of a plurality of power distribution units 3 and a common bus bar unit, and the power distribution unit 3 has a row panel structure. The power distribution unit 3 and the common bus bar unit can be separated from each other. As a result, it is easy to change the switchboard when the load increases, and the switchboard combination design is facilitated by being unitized.

る。In the present invention, the circuit breakers are placed horizontally and the three phases are stacked in the height direction. However, this is not necessarily intended to be stacked on the same plane, and some circuit breakers are horizontal. They may be arranged separately in the direction. Rather,
In some cases, the circuit breaker may be arranged so that it can be moved in the horizontal direction. In the embodiment, the power source side contactor is in contact with the horizontal bus bar, but when the contact state at this portion deteriorates, it is possible to recover the deterioration of the contact state by shifting the contact position in the horizontal direction. Further, the arrangement of the contact on the load side can be shifted to some extent as on the power supply side.

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.

It is possible. In the embodiment, the circuit breaker side is the convex portion and the bus bar side is the concave portion for detachable direct connection, but this relationship may be reversed. Although the contactor is attached to the circuit breaker side, it may be possible to have the contactor on the bus bar itself.
