The present invention relates to a control center for storing the plug-in type control unit stacked in multiple stages.

In general, most control centers have a double-sided type that accommodates control units on the front and rear sides, and the vertical bus divisions in which the vertical buses for distribution to each control unit are wired are placed in the center, and the front and rear of the vertical bus divisions Two unit compartments are provided for stacking and storing control units in multiple stages, and vertical line compartments are provided adjacent to side surfaces of the unit compartments.

In addition, the horizontal busbar compartment and the cable treatment compartment are respectively provided at the upper and the bottom of the box constituting the above compartments.

In FIG. 1, 1 is an embodiment of a conventional control unit housed in a control center, and 2 is a U-shaped unit case comprising a left plate 2A, a right plate 2B, and a back plate 2C.

3 is a front transverse member, 4 is a rail, 6 is a circuit breaker for wiring, 5 is a mounting plate to which an electromagnetic switch is installed, 11 is a control transformer installed on the rear thereof, and 12 is a rear side of the unit case. It is placed and plugged into the vertical busbar.

In other conventional examples, an electric apparatus may be installed on the unit case back plate 2C without installing the mounting plate 5.

When the conventional control unit 1 is withdrawn from the control center box and the door of the empty unit room is opened, the vertical busbar is exposed and dangerous.

Therefore, conventionally, resin barriers were provided between the unit case rear surface and the vertical bus bar.

An example of this is shown in Japanese laboratory 52-56423.

As another example, there may be a sandwich between the vertical busbar and the entire vertical busbar as a resin case.

All of the above are expensive, and require high quality resin products, which is uneconomical.

In addition, the control unit 1 enters the cable into the electromagnetic switch 7 or the terminal block in the unit on the right side plate 2B side.

A cutout 2D is provided to prevent the end of the cable from being caught by the back plate 2C when the unit is taken out.

However, the size of the cutout is often insufficient due to the thickness of the cable and the number thereof.

In addition, the control center box has a drawback in that the strength of the left and right directions is weak because the front and rear sides of the control unit are prevented from attaching and detaching the control unit.

The present invention has been made in view of the above circumstances, and is intended to eliminate the conventional drawbacks by the construction of a novel unit case and vertical busbar compartment.

One embodiment of the present invention will be described in detail with reference to FIGS.

In the figure, 100 is a control center of the present invention, and is generally arranged in a plurality of niches.

Denoted at 101 is a unit partition on the front side including unit rooms 201, 202, 203, 204 and the like.

22 is a support plate extending from one L-shaped support angle 20C, whereby the main line segment 102 and the vertical bus segment 105 are separated.

The unit compartment 101 is divided into the above unit rooms by the partition plate 24.

The front and rear end surfaces of the partition plate 24 are bent upward to form vertical angles 24A and 24B, and both end ends thereof extend downward to form a J-shaped guide rail 24C.

The partition plate 24 fixes the front part to the U-shaped support angle 20A and the intermediate column 21 using the guide rails 24C, and the back portion protrudes from the guide rails 24C. 24D) is inserted in the L-shaped support angle 20C and the support plate 22, and is supported.

25 is a steel plate back plate provided in the back of each unit room, The lower end is provided with the edge part 25B which overlaps with a partition board and the back vertical angle 24B.

A part of the end portion 25B is bent to the opposite side to form the engagement piece 25C sandwiching the rear vertical angle 24B.

The left and right ends of the back plate 25 are fixed to the screw member 27 by overlapping the L-shaped support angle 20C and the support plate 22, respectively.

The upper end is formed with an L-shaped curved angle 25D in contact with the partition plate 24, and an opening 25A through which the protrusion housing 12B of the insertion connecting device 12 penetrates is provided below.

Through the opening 25A, the full length 40B or 40C of the vertical bus bar 40 can be observed (FIG. 5).

The back plate 25 is provided in all unit rooms including the empty unit room 202.

Therefore, as shown in FIG. 26, a separate size (only different in height) is provided according to the height of the unit chamber.

The partition unit compartment 101 is separated from the vertical busbar compartment 105 by the back plates 25 and 26.

40 is a Z-shaped vertical busbar having a full length 40B and a rear angle 40C extending in opposite directions from both ends of the middle portion 40A parallel to the rear plate, and having an insulating support device (not shown). It is fixed to L-shaped support angle 20C.

A representative control unit 41 housed in the control center above is shown in FIG.

This unit case consists only of the side plates 14 and 15 which consist of flat plates on the left and right sides.

3 is a front transverse member, which is used as a latch device (not shown) or as a takeout knob.

4 is a rail installed above the side plates 14 and 15, 5 is a circuit breaker 6 for wiring, an electronic switch 7, a terminal block 13 (FIG. 3), and an electrical apparatus such as a control transformer 11 on the back side. Is an installation plate that is installed.

On the circuit breaker 6, an operation handle device 8, a control panel 9 which is formed integrally with the switch 10 and is installed, is mounted.

However, in order to simplify the drawing, the mechanism part of the operation handle device is omitted.

16 is a rear transverse member having an L-shaped cross section, and a plug-in connecting device 12 is mounted.

The plug-in connection device 12 has three protrusion housings 12B, each having a U-shaped contact 12A therein and connected to a wiring breaker through a lead wire 12C.

The side plates 14 and 15 are connected by the horizontal members 3 and 16 and the mounting plate 5.

The side plate 15 is provided with cutouts 15A for introducing cables.

The state in which the unit 41 is accommodated in the unit 203 is shown in FIGS. 3 and 4.

The projection housing 12B of the plug-in connecting device penetrates through the opening 25A of the back plate, and the contactor 12A therein is plug-in-connected with the vertical bus line 40.

Moreover, the operation handle 8 and the control panel 9 protrude outward from the opening 203B of the unit door 203A.

The rear ends of the side plates 14 and 15 are in contact with the L-shaped support angle 20C and the support plate 22 so that the unit chamber 203 is separated from the vertical line section by the side plates 15.

Since the mounting plate 5 is located in front of the rear end of the side plates 14 and 15, the head of the screw member 27 does not interfere.

The space between the back plate 25 and the mounting plate 5 can be used as a wiring space or a device space that does not require operation.

The rear transverse member 16 is located slightly lower than the front transverse member 3, so that the gap with the bottom surface of the partition plate 24 is large, so that the rail 4 can be easily inserted into the guide rail 24C. In the storage position, the L-shaped curved angle 25D of the rear plate is accommodated on the upper side of the rear transverse member 16, and the front transverse member 3 is almost in contact with the bottom surface of the partition plate 24 so that the vertical vibration during transportation Be limited.

As shown in FIG. 5, the fixing screw member 27 of the back plate can be increased by any number of two or more left and right.

Thus, the back plate also serves as a reinforcing plate of the box in addition to serving as a barrier or a shielding plate.

In this regard, as is apparent from FIG. 4, in combination with the wall plate 20, the entire cross-section becomes H-shaped, which is a strong structure in any direction.

28 is a lid attached to the rear plate opening 25A of the empty unit chamber, and even if the empty unit door 202A without the interlock device is opened, the charging exposure unit is secured at all (FIG. 5).

The control center of the present invention configured as described above has many features as follows.

1.The installation plate on which the electric equipment of the control unit is installed is installed between the left and right side plates so as to be approximately H-shaped in the horizontal direction, and the rear plate for each unit stored in the rear side at the final storage position is fixed to the unit box Therefore, the vertical busbar of the unit room or the empty unit room after taking out the unit is shielded and safe.

2. Since the above back plate is installed at the same corner position as the back of the conventional unit case, the insulation distance from the vertical bus is sufficiently secured and can be made of steel sheet.

Therefore, it is extremely economical as compared with conventional resin barriers or busbar sandwich covers.

3. The unit compartment and vertical busbar compartment are separated by the back plate made of steel plate, so if any arc occurs, there is no accident spreading and there is no insulation deterioration by the arc.

4. Since there is no back plate in the unit case, the vertical part of the end of the cable drawn in from the side plate cutout 15A is not caught, so that the unit take-out operation can be facilitated.

In addition, when the multi-pole connector inserted into the terminal block 13 is used, since the multi-pole connector is caught by the unit case back plate 2C, it is necessary to pull out the next unit hanging for each cable out of the front of the unit chamber. According to the present invention, the multi-pole connector can withdraw the unit while remaining on the partition board 24.

Therefore, the withdrawal operation is easy and the cable terminal portion is not damaged at the front vertical angle 24A of the partition plate.

5. Since the unit can be directly contacted with the front and rear surfaces of the mounting plate 5 in the state where the unit is pulled out (Fig. 6), it is extremely easy to replace, repair, and wire the rear mounting equipment such as a control transformer. can do.

6. The back plate can act as a reinforcement of the box by increasing the fixed location, so it can be used in the control center for ships or nuclear power plants that require economic shock and shock resistance. .

7. In the conventional resin barrier or busbar sandwich cover, it is necessary to install an opening for the insertion connection device according to the standard height of the unit. Therefore, a plurality of lids are needed to block unnecessary openings. There is no need to prepare.

8. Since the left and right ends and the bottom of the back plate overlap with the box support plate and the partition plate, there is no gap so that the shielding between the unit chamber and the vertical busbar compartment becomes more reliable than before.
