Description

Switchboard for generator of ship {SWITCH BOARD FOR GENERATOR OF MARINE}

TECHNICAL FIELD This invention relates to the connection technology of the generator distribution board of a ship, especially its main bus | line.

The ship is equipped with a plurality of generators, and electric power from each generator is supplied to the load via the main circuit bus common to the breakers and all the generators corresponding to each generator. Fig. 6 is a wiring diagram inboard on which these three generators G1, G2 and G3 are mounted, and the generators G1, G2 and G3 are connected to the main bus 4 through breakers 1, 2 and 3, respectively. have. The main bus 4 can be divided into two sides from the left and right by a disconnecting device. Usually, the main bus 4 is fed into the ship with the disconnecting device 5 connected, and any feeder circuit 6 or 7 When a failure occurs, the disconnecting device 5 is disconnected to continue feeding only to a healthy circuit.

FIG. 7 shows a generator switchboard for the generator G2 of FIG. 6. One switchboard is provided for one breaker for the reason of the insulation that a plurality of breakers must be electrically isolated from each other. Although not shown in FIG. 7, generators G1 and G3 are located on the left and right of the switchboard with respect to generator G2. Each switchboard for is added. Each of the generators G1, G2, G3 is a three-phase generator, and as shown in Fig. 7, a connecting rod between the breaker 2 and the main bus 4 arranged upward in the switchboard is shown in Fig. 7. Is connected. In addition, in FIG. 7, the main bus 4 and the disconnecting device 5 are arrange | positioned three-phase-distributing toward the back surface from the surface of the paper surface. The main bus 4 is installed by inserting three switchboards provided next to each other. Since such breakers, disconnectors, and main buses have relatively large current capacities, they are large and inflexible in installation.

On the other hand, since the ship is limited in space, the size of the switchboard should be made as small as possible, but the width of one switchboard cannot be made smaller than the width of the breaker. For example, even if the widths of the two switchboards in which the disconnector 5 is not accommodated can be made slightly larger than the width of the breaker, as shown in FIG. 7, the switchboard in which the disconnector 5 is housed is connected to the disconnector 5. There was a problem that it became large enough to store.

It is therefore an object of the present invention to provide a generator switchboard for a ship which can make the width as small as possible.

In order to solve the above problems, the invention of claim 1 is a generator switchboard for a ship equipped with a three-phase generator, and includes a plurality of circuit breakers installed in parallel in a horizontal direction, and extends in a horizontal direction from above the plurality of circuit breakers, respectively. At the same time, between the three-phase main bus bar that is installed to be shifted in the vertical direction to each other, the connecting rod extending vertically upward from the three-phase terminals of each breaker and connected to the corresponding main bus bar, and between each connecting bar and the corresponding main bus bar. A relay conductor is provided to move the connection position on the main bus in the horizontal direction.

With such a configuration, since the connection position with the breaker in the main bus can be freely moved, the space for attaching other equipment to the main bus, the holding space of the main bus, etc. increase.

The switchgear for generators of the ship of Claim 2 has the connection part of the switchboard of Claim 1 between the connection part with the relay conductor corresponding to one breaker of each main bus | line, and the connection part with the relay conductor corresponding to the other breaker. The disconnector is connected to the.

In the switchgear for generator of the ship of Claim 3, in the switchgear of Claim 1 or 2, the connection position of the relay conductor of each phase corresponding to one or more breakers, and a main bus | line is parallel to a perpendicular line when seen from the front. With this configuration, since the positions of the three-phase relay conductors do not deviate from the horizontal direction, the space for connecting other equipment on the main busbar increases without concern for the width dimension of the breaker.

In the switchgear for generators of the ship of invention of Claim 4, in the switchgear of Claim 3, a perpendicular line is supposed to correspond with the centerline of the breaker.

Embodiment of embodiment

Embodiment of this invention is described in the Example shown to FIGS. As shown in FIG. 1, in the generator switchboard of the ship of this embodiment, the breakers 1, 2, and 3 shown in FIG. 6 are housed in a line in the left-right direction of the front of the switchboard 10, and are adjacent to each other. The breakers are separated from each other by the partitions 11 and 12.

The spacing between these breakers and the gap between the breakers and the side plates 10a of the switchboard 10 are set small. As shown in FIG. 2, the main buses 13, 14, and 15 of three phases which extend in a horizontal direction are shift | deviated in the vertical direction, respectively, above the breaker, and are arranged between the breaker 2 and the breaker 3, respectively. It is attached to the disconnectors 16, 17, and 18 on the busbar buses 13, 14, and 15, respectively. The disconnectors 16, 17, and 18 operate the handles 16a, 17a, and 18a, respectively, to open and close, but the main busbars are shifted in the vertical direction to facilitate operation.

Referring to the circuit breaker 2 on behalf of the circuit breakers 1, 2 and 3, the terminals 19, 20 and 21 are connected to the main buses 13, 14 and 15 via the connecting leads 22, 23 and 24. Is connected to. In addition, the center connecting band 23 is connected to the main bus line 14 on the center line C of the circuit breaker 2 via the relay conductor 26 shown in FIG. In addition, the connecting rod 22 and the connecting rod 24 are connected to the main bus lines 13 and 15 on the center line C of the circuit breaker 2 via the relay conductors 25 and 27 having the structure shown in FIG. 5. Connected. That is, when viewed from the front or the back of the switchboard 10, the connection points of the respective phases are connected in parallel in a vertical direction. As a result, the respective disconnectors 16, 17 and 18 and the main buses 13, 14 and 15 are connected to the connection band 24 at the right end of the circuit breaker 2 or to the left end of the circuit breaker 3. Since the connection can be made without interfering with 30, it is not necessary to widen the width of the switchboard 10 in order to connect the disconnectors 16, 17, and 18.

As described above, it has been explained that it is not necessary to increase the width of the switchboard for attaching the disconnecting device by moving the connection position with the connection band in the main bus bar. However, the degree of freedom also increases as to the support position of the main bus bar if necessary. .

Embodiment of this invention disclosed above is an illustration to the last, and the scope of the present invention is not limited to embodiment of said invention. The scope of the present invention is shown by description of a claim, and it is intended to include description of a claim, the meaning of equality, and all the changes within a range.

The present invention is implemented in the form described above, and since the connection position with the breaker in the main bus can be freely moved, the position where the apparatus such as the disconnecting device is attached to the main bus and the attachment position of the member supporting the main bus The selection range of increases, resulting in an effect of reducing the size of the switchboard.
