Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a distributed power circuit control panel, and in particular, to a power circuit control panel of a distributed type. This relates to a control panel in which a unit part is mounted in a housing.

[Prior art] Distributed power circuit control panels control power supply to various loads including motors included in one block of equipment, but in the past, implementation efficiency could not be improved. There are problems such as.

That is, FIG. 1 shows a power circuit control panel according to the prior art.According to this, a power control unit part 2, an analog calculation unit part 3, an operation monitoring unit part 4, and a control unit part 5 are installed inside a housing 1.
are accommodated and mounted as shown.

To briefly explain the relationship between each unit section 2 to 5, the power control unit section 2 consists of an electromagnetic magnet, MCCB, etc., and controls the power supply to various loads according to commands from the control unit section 5. There is. The control unit section 5 performs necessary calculations according to various loads and process conditions from the analog calculation unit section 3 and operation commands from the operation monitoring unit section 4, and also issues power supply on/off commands to the power control unit section 2. I try to give. The operation/monitoring unit section 4 not only monitors the status of various loads and processes, but also operates the various loads.

Further, only one of each unit section 2 to 5 is provided corresponding to one block of equipment, and the shape and dimensions thereof are configured and mounted in advance. The casing 1 is formed by each frame 7, and a door 6 is attached to the front surface of the casing 1 so as to be openable and closable.

However, when implementing and accommodating as described above,
There is a problem in that it is difficult to increase mounting efficiency. This is because the shape and dimensions of each unit part are determined regardless of the number of loads, so when the number of loads is small, the shape and dimensions of the power control unit part 2 can be small. This means that other units cannot be mounted in that mounting space. Furthermore, the control unit section 5, which is susceptible to noise, is mounted on the same frame 7 as the power control unit section 2, but since the power control unit section 2 includes an electromagnetic magnet, etc. This also has the disadvantage that the control unit section 5 is likely to malfunction due to noise transmitted through the frame 7 from the control unit section 2.

[Object of the Invention] In view of the above-mentioned circumstances, an object of the present invention is to provide a distributed power circuit control board which can improve mounting efficiency and whose control unit section is less likely to malfunction.

[Summary of the Invention] The present invention includes forming a first chamber and a second chamber within a housing, and forming the power control unit section separately into a number corresponding to the number of loads.
The power control unit section, the analog calculation unit section, and the operation monitoring unit section are each formed to have the same size and shape, and the power control unit section, the analog calculation unit section, and the operation monitoring unit section are arranged in the first part of the housing. The control unit section is mounted on the door of the case, and when the door is closed, the control unit section is mounted in the second room of the case without contacting the frame that constitutes the second room of the case. It is characterized by the fact that it is located in a room where the above object is achieved.

[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to FIG.

The distributed power circuit control panel of the embodiment includes, within a housing 1, a power control unit section 2 that supplies power to various loads, and an operation monitoring unit section 4 that monitors the status of various loads and processes and operates various loads. , an analog calculation unit section 3 which inputs and processes the state quantities of various loads and processes, performs calculations based on the load operation command and the converted state quantities, and then gives a power on/off command to the power control unit section 2. A control unit section 5 is mounted respectively. Housing 1
A door 6 is attached so that it can be opened and closed. This point is similar to the conventional example.

Thus, in this embodiment, a first chamber 1A and a second chamber 1B are formed inside the housing 1, respectively. That is, the first room 1A is defined by the upper frame 7b of the housing 1, the side frames 7c and 7d, and the partition frame 7f installed horizontally between the lower sides of these side frames 7c and 7d,
The second room 1B is defined by the partition frame 7f, the lower parts of the side frames 7c and 7d, and the lower frame 7a, and is located below the first room 1A.

On the other hand, the power control unit sections 2 are formed separately in numbers corresponding to the number of loads, for example, the number of motors. Further, the power control unit section 2, the analog calculation unit section 3, and the operation monitoring unit section 4 are formed to have the same external dimensions. in this case,
The analog calculation unit section 3 and the operation monitoring unit 4 do not correspond to the number of loads, and are configured as one or more units so as to have the same dimensions and shape as the power control unit section 2.

The power control unit 2, analog arithmetic unit section 3, and operation monitoring unit section 4 are arranged and mounted in the first room 1A of the housing 1. That is, in the first room 1A of the casing 1, an appropriate number of power control units are installed between the central frame 7e, which is provided upright in the middle of the upper frame 7b and the partition frame 7f, and one side frame 7c. 2 are stacked and stored, and an analog calculation unit section 3, an operation monitoring unit section 4, and a power control unit section 2 are stacked and stored between the central frame 7e and the other side frame 7d. 2 to 4 are also mounted by screws or the like.

On the other hand, the control unit part 5 is attached to the inner lower part of the door 6, and when the door 6 is in the closed state of the housing 1, it comes into contact with both side frames 7c and 7d, the partition frame 7f, and the lower frame 7a. It is located in the second room 1B of the housing 1 instead of being located in the second room 1B of the housing 1.

As described above, in the distributed power circuit control panel of the embodiment, the power control unit section 2 is formed separately in a number corresponding to the number of loads, so that the power control unit section 2 is formed separately according to the number of loads. 2 will be used, and each of the power control unit section 2, analog calculation unit section 3, and operation monitoring unit section 4 will be used.
Since each of them has the same size and shape and is mounted in the first room 1A of the housing 1, the required mounting space in the first room 1A can be minimized.
In other words, each of the unit sections 2 to 4 can be efficiently mounted to support a larger load.

Further, the control unit part 5 is attached to the inside of the door 6, and when the door 6 is closed, the control unit part 5 is attached to the inside of the second room 1.
Each frame 7a, 7c, 7d, 7f configuring B
Since it is located in the second room 1B without coming into contact with the power control unit section 2, it is spatially and frame-wise isolated from each power control unit section 2, and as a result, the influence of electromagnetic noise is alleviated. The unit 5 is less likely to malfunction. In addition, since the influence of noise can be alleviated simply by changing the arrangement of the control unit section 5, there is no need to shield the control unit section 5 or each power control unit section 2 itself.

Although the illustrated embodiment shows an example in which the second chamber 1B housing the control unit section 5 is placed below the first chamber 1A, the second chamber 1B housing the control unit section 5 is placed below the first chamber 1A. Of course, it is also possible to provide one.

[Effects of the Invention] As described above, according to the present invention, each power control unit section, analog calculation unit section, and operation monitoring unit section, which are formed separately according to the number of loads, are formed in the same size and shape, and these Since the unit is configured to be mounted in the first room of the housing, the power control unit is used in proportion to the number of loads, and the required mounting space in the first room is reduced. As a result, the mounting efficiency can be improved as much as possible. In addition, since the control unit section is configured so that it is located in the second room without touching the frames that make up the second room with the door closed, the control unit section is isolated from each power control unit section. As a result, the influence of electromagnetic noise is alleviated and the control unit becomes less likely to malfunction, which increases reliability accordingly.Moreover, there is no need to shield the control unit itself or each power control unit itself. This has the effect of easily realizing noise countermeasures.
