Description

[Detailed description of the invention] This invention relates to a control center in which a vertical busbar of a load center panel and a horizontal busbar of a horizontal control center panel are connected to a load center unit provided on the load center panel. Ru.

Conventional control centers had the disadvantage that the wiring for the panel was extremely complicated and difficult because power was supplied to the panel in which the units were housed through a rib duct from the top or bottom of the panel.

In addition, when adding units, the panels are installed horizontally in rows, which requires connection of the busbars between the panels, which requires laborious wiring work and has the drawback of making expansion difficult. there were.

By the way, conventionally, the power supply side vertical busbar and the load side horizontal busbar in the front and rear direction of multiple circuits arranged in multiple stages are installed in the panel, and the vertical busbar and arbitrary There is one that simplifies the wiring work by connecting it to the horizontal busbar of the circuit.

However, in this case, the depth of the panel increases and the installation location is limited.Furthermore, when this is applied to a control center, it becomes extremely difficult to connect a large number of control center units to the horizontal busbar. It becomes difficult,
Not practical.

This idea was made with the above points in mind,
Next, this invention will be explained in detail with reference to drawings showing one embodiment thereof.

In the drawing, 1 is a transformer board, 2 is a transformer installed in the transformer board 1, 3a, 3b, and 3c are 3-phase secondary side terminals of the transformer 2 that protrude side by side from the top surface of the transformer 2 in the left and right direction, 4 5a is a load center board provided on the side of the transformer board 1.

5b and 5c are three-phase vertical busbars arranged side by side in the left and right direction in the load center board 4, and 6a, 6b and 6C are secondary side terminals 3a and 3b of the transformer 2 at one end.

3c, and the other end is a vertical bus bar 5a.

5 by 5 c are respectively connected to the secondary bus busbars, and 7 is a horizontal control center board provided in multiple stages in the vertical direction on the opposite side of the load center board 4 from the transformer board 1. The load center board 4 and the horizontal control center board 7 are installed in rows.

8a, 8b, and 8c are three-phase horizontal busbars arranged vertically in each horizontal control center panel 7, and the left ends of the horizontal busbars 8a, 8b, and 8c are connected to the load center panel 4. It has been introduced.

Reference numeral 9 denotes a load center unit that is provided in a position corresponding to any horizontal control center panel 7 of the load center panel 4 so as to be accessible from the front. 10a
, 10b, 10c are connected to the vertical busbars 5a, 5b, 5c, and the connectors lla, llb, llc are connected to the horizontal busbars 8a, 8b of the horizontal control center board 7.

8c, and the vertical busbars 5a, 5b, 5C
and horizontal bus lines 8a, 8b, and 8c are connected for each phase.

12 is a plurality of control center units housed side by side in the horizontal control center panel 7;
Connector 1 on the rear of each control center unit 12
3, each control center unit 12 can be freely moved toward and away from the horizontal bus lines 8a, 8b, and 8c.

The power supply to the horizontal control center board 7 of each stage is connected to the transformer 2 and the secondary side terminal 3a.

3b, 3c, secondary bus bus lines 6a, 6b, 6c.

Vertical busbars 5a, 5b, 5c, load center unit 9, horizontal busbars 8a, 8b, 8c, and each control center unit 12 has a horizontal busbar 8a.

Power is supplied from 8b and 8c.

Therefore, according to the embodiment, the vertical busbars 5a, 5b
, 5c and the horizontal busbars 8a, 8b, 8c can be easily connected to the load center unit 9 of the load center panel 4, so that power can be easily supplied to each horizontal control center panel 7 at each stage. Moreover, in each horizontal control center panel 7, a plurality of control center units 12 can be stored side by side from the front in the left and right direction, and when adding this type of unit 12, the horizontal control center panels 7 can be stacked in multiple stages. The horizontal generatrix 8a of the lever
, 8b, 8c need only be connected to the vertical busbars 5a, 5b, 5c by the load center unit 9, making expansion extremely easy.

Further, since the vertical busbars 5a, 5b, 5c of the load center board 4 are arranged side by side in the left-right direction, and the horizontal busbars 8a, 8b, 8c in the left-right direction of the horizontal control center board 7 are arranged side by side in the vertical direction. , the entire control center can be made thin, which is extremely advantageous when installing in cases where there is a limit in the depth direction.

Furthermore, by connecting the secondary side terminals 3a, 3b, 3c of the transformer 2 of the transformer panel 1 provided on the side of the load center panel 4 to the vertical busbars 5a, 5b, 5c, power is supplied from the substation to the load. A series of constructs can be obtained.

As described above, according to the control center of this invention, three-phase horizontal busbars are arranged vertically on the side of a load center board on which three-phase vertical busbars are arranged horizontally. A plurality of horizontal control center boards are provided in multiple stages in the vertical direction, and the ends of the horizontal busbars of each of the horizontal control center boards are introduced into the load center board, and the vertical busbars and the vertical busbars are inserted into the load center board. A load center unit is provided that connects the horizontal bus bar in any of the horizontal control center panels from the front, and the horizontal bus bar is connected to the vertical bus bar.The horizontal bus bar is connected to the vertical bus bar. By storing the load center units side by side in the left and right direction, it is possible to simplify the connection between the vertical bus bar and the horizontal bus bar, making it extremely easy to supply power to each level of horizontal control center panels. In addition, it is easy to add more units, and the control center as a whole can be made thinner, making it possible to install it in places with limited depth.
