Therefore, in each of the intermediate boards 1B to 1E, a lead-in relay terminal block 6 for relaying the control / communication cable 5 of each board that is lined up on the right side is required, and the number thereof increases, especially the lead-in board. In the board 1B, which is close to the board 1A, all the other cables penetrate through the board, so that the number of the terminal blocks 6 becomes very large, and there is a problem in that there are no mounting points.

Here, if the pull-in board 1A is arranged in the middle of the row board, the total number of the pull-in relay terminal blocks 6 can be reduced. It is not a good idea in terms of wiring work and workability, and even though the number of terminals has decreased, in the board adjacent to the drawing board, it is a relay terminal block for drawing in to connect cables from other boards. 6 must be provided, and there is a problem that the number is still large.

On the other hand, in the above-described row board device, since the relay terminal block 3 and the pull-in terminal block 4 or the pull-in relay terminal block 6 are arranged close to each other in each of the panels 1A to 1E, the relay terminals are The power cable 2 connected to the stand 3 and the control / communication cable 5 connected to the pull-in terminal block 4 or the pull-in relay terminal block 6 are mixed in the same space, which may be mistaken during wiring inspection. There is a problem in that the power cable 2 may be touched and lack safety.

The present invention has been made in view of such problems of the conventional technology, and the purpose thereof is to minimize the number of lead-in relay terminal blocks in each board. Another object of the present invention is to provide a switchgear train panel device that can be suppressed and can improve safety during wiring inspection.

Separate the relay terminal block room in which the terminal block is placed from each other, and install a pull-in relay terminal block on each panel other than the pull-in panel that pulls in and pulls out the cables. Each of the relay cables is routed directly through the relay cable room to the lead-in terminal block of the lead-in board.

[0009]

[Action]

 In the switchgear row panel device with the above-mentioned configuration, in each panel other than the pull-in panel, the cables from each panel pass through the relay cable room that penetrates from the pull-in relay terminal block to each panel. Since it is directly wired to each pull-in terminal block of the pull-in board, only the relay terminal block for power cable and the pull-in relay terminal block are arranged in each board other than the pull-in board, and the minimum number of terminals is required. .

Further, since the relay cable chamber penetrating between the boards and the relay terminal block chamber are formed separately, the relay cable in the relay cable chamber and the power cable in the relay terminal block chamber are reliably separated. Can be distinguished and the safety at the time of wiring inspection can be maintained.
