Description

  The present invention relates to a switchgear in which a device such as a switch used for a power distribution device is housed in a metal closed box.

Conventionally, switchboards used in switchgears installed indoors or outdoors such as substations include those shown in FIGS.
FIG. 3 is a front view showing a conventional switchboard. FIG. 4 is a schematic side sectional view showing a state where the frame is divided into two frames. 101 is a control room, 102 is a circuit breaker room, 103 is a main bus room, 104 is a cable room, and 105 is a door.

  In manufacturing a switchgear, it is often manufactured by dividing it into two frames on the front and rear sides due to manufacturing size limitations. Specifically, as shown in FIGS. 4 and 5, the front part is divided into a control chamber 101 and a circuit breaker room 102, and the rear part is divided into a main bus room 103 and a cable room 104 (see Patent Document 1).

  Moreover, when not dividing | segmenting into two frames before and behind, the content which divides | segments and manufactures in several compartments for each storage apparatus, such as a control room and a circuit breaker room, is disclosed (patent document 2).

  For example, FIG. 5 shows a case where the control room and the circuit breaker room are divided. FIG. 5 is a cross-sectional view showing a conventional switchboard, and shows a state where a control room and a circuit breaker room are divided.

Such conventional switchboards have the following problems.
When manufacturing the whole as a single case without dividing it, when the control circuit is different for each type of switchboard, the change in the control circuit will affect the overall design, making it easy to change Can not do. It is also difficult to standardize each circuit configuration of the switchboard.

  On the other hand, when the front and rear parts are manufactured, the device can be incorporated during the assembly of the frame. However, although the wiring work of the control device accommodated in the control room takes the most time, the wiring work cannot be performed unless the assembly of the respective frames is completed. Therefore, it is difficult to shorten the production work time.

  In addition, if the frame is not divided into two frames at the front and back, but is divided into a plurality of compartments for each chamber, the frame of the circuit breaker room and the main bus room is irregular (partially a chimney-like convex shape) (For example, the circuit breaker chamber 102 in FIG. 5). For this reason, there are problems that the accuracy of designing and assembling becomes low and that it takes a lot of time for manufacturing.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to realize a switchboard that can shorten the working time with a simple configuration in order to solve the above-described problems.

In order to achieve the above object, according to the present invention, a circuit breaker chamber for storing a circuit breaker, a control chamber for storing a control device disposed on the circuit breaker chamber, and a rear part of the circuit breaker chamber In the switchboard in which the main bus room for storing the main bus and the main bus room for storing the main bus room and the cable room for storing the cables arranged at the rear of the main bus room are divided, the circuit breaker room and the control room are: Each box is a rectangular parallelepiped , and the depth dimension of the control room is smaller than the depth dimension of the circuit breaker room, and covers the space between the control room and the main bus room. The switchboard is characterized in that an auxiliary member composed of a ceiling plate and a pair of side plates is arranged between the bus bar room .

  According to the present invention, it is possible to realize a switchboard that can reduce the working time with a simple configuration.

It is a schematic sectional side view which shows the switchboard divided | segmented into the some flame | frame of the Example of this invention. It is a schematic sectional side view which shows the state assembled by adding the auxiliary member of the Example of this invention. It is a front view which shows the conventional switchboard. It is a schematic side sectional view of a conventional switchboard, and shows a state divided into two frames. It is sectional drawing which shows the conventional switchboard, and is the figure which showed the state by which the control room and the circuit breaker room were divided | segmented.

  Embodiments will be described in the following examples.

The configuration of the embodiment of the present invention will be described.
First, the configuration of the switchboard will be described with reference to FIG.
FIG. 1 is a schematic side sectional view showing a switchboard divided into a plurality of frames according to an embodiment of the present invention. 1 is a control room, 2 is a circuit breaker room, 3 is a main bus room, 4 is a cable room, 5 is a control device, 6 is a circuit breaker, 7 is a main bus, 8 is a cable, and 9 is a door.

  As shown in FIG. 1, the control room 1 and the circuit breaker room 2 are each configured as one box (frame). The main bus room 3 and the cable room 4 are configured as a single box, and are formed as a rectangular parallelepiped without any particular irregularities.

In addition, the depth dimension of the control room 1 is arbitrarily set by a numerical value smaller than the depth dimension of the circuit breaker room 2.
That is, the circuit breaker chamber 2 is composed of a part that houses the circuit breaker 6. Accordingly, the chimney-like convex portion extending between the control room and the main bus room as in the prior art is not formed in the circuit breaker room 2.

The front sides of the control room 1 and the circuit breaker room 2 are closed by doors 9 that can be opened and closed.
Each room accommodates each electrical device separately. Specifically, a control device 5 is stored in the control room 1, a circuit breaker 6 is stored in the circuit breaker room 2, a main bus 7 is stored in the main bus room 3, and a cable 8 is stored in the cable room 4.

As will be described later, a switchboard is manufactured by combining boxes containing these electric devices.
The configuration of the switchboard is as described above.

Next, the production of the switchboard will be described with reference to FIG.
FIG. 2 is a schematic side sectional view showing a state where the auxiliary member according to the embodiment of the present invention is added and assembled. 10 is a ceiling board (auxiliary member), 11 is a side plate (auxiliary member).

  As shown in FIG. 2, the control chamber 1 is disposed and coupled to the front top portion of the circuit breaker chamber 2. Then, behind the control room 1 and the circuit breaker room 2 combined in this way, the main bus room 3 and the cable room 4 are arranged and combined as one box. In addition, they are couple | bonded by suitable coupling | bonding means, such as a rivet or a bolt, or welding and an adhesive agent.

  Here, the circuit breaker chamber 2 is formed as a rectangular parallelepiped with no irregularities, and the depth dimension of the control chamber 1 is arbitrarily set to a numerical value smaller than the depth dimension of the circuit breaker chamber 2. Therefore, a space is created between the control room 1 and the main bus room 3 simply by combining the boxes.

  Therefore, the ceiling plate 10 and the side plate 11 are arranged as auxiliary members between the control room 1 and the main bus room 3. Thereby, the space between the control room 1 and the main bus line room 3 can be closed, and the whole switchboard can be formed as one box.

This is the end of the switchboard production.
Thus, according to the embodiment of the present invention, since the control room 1 is separated and configured as a single box, even if the control circuit is different for each type of switchboard, it is possible to cope with it by changing only the control room 1 It becomes possible to do.

Moreover, since each room including the control room 1 is configured separately for each frame, it is possible to standardize the entire circuit of the switchboard.
Furthermore, in the production of the switchboard, the control room 1 and the circuit breaker room 2 are individually produced, and the assembled control room 1 (wiring of control equipment) is assembled to the circuit breaker room 2 that has been assembled. Therefore, production time can be shortened without being restricted by assembly work.

  In addition, by using auxiliary members (the ceiling plate 10 and the side plate 11) in the divided configuration of the switchboard, it is not necessary to make the shape of the circuit breaker chamber 2 complicated. As a result, manufacturing is facilitated, design and assembly accuracy is improved, and work time can be shortened.

  The above embodiment has been described with reference to a preferred example, and it goes without saying that various modified examples are possible without departing from the spirit of the present invention. That is, the dimensions of the control room, the circuit breaker room, the main bus room, the cable room, etc., the shape of each part, and the like should be variously changed according to the requirements and circumstances of the installation site.
