Schematic configuration views for explaining a modified example of the boards 10A to 10C ((A) to (C) are views of the inside of the board with the left side surface portion 11d removed).

The cooling structure of the panel according to the embodiment of the present invention includes a pair of support rails extending in the direction of taking in and out of the stationary guidance device (hereinafter, simply referred to as the direction of entering and exiting the device) on the bottom side of the board in the board body. It is characterized by using a protective cover that divides the inside of the panel body into a space on the intake port side and a space on the stationary guidance device side.

In the case of the cooling structure of this embodiment, among the panel side portions of the panel body (the panel front portion 11a, the panel back surface portion 11b, the panel right side surface portion 11c, and the panel left side surface portion 11d in FIG. 1 described later) in the device entry / exit direction. On one side of the board (front side of the board 11a or back of the board 11b), which is one side, an intake port communicating with the space on the side of the intake port in the main body of the board is provided.

On the outer surface of the closing lid that closes the upper side of the portion, a through hole on the intake port side and a through hole on the stationary guidance device side are provided so as to communicate with the track space portion.

For example, in the case of the conventional cooling structure, it is difficult to provide a protective cover in the intake port side region because a duct such as a partition wall is provided in the intake port side region in the panel body.

In particular, in the case where a plurality of board members (for example, board panel, columnar frame, bracket, partition plate, opening / closing door, etc.) are complicatedly assembled in the board body, a protective cover can be provided. Even so, there is a risk that the board will become complicated, the cost will increase, and the cooling performance, maintainability, etc. will be impaired.

There is also the possibility of realizing various designs.

Further, as compared with the conventional cooling structure, since the cooling structure is simplified and it is easy to suppress the pressure loss, it is easy to obtain the desired cooling property, maintainability, etc., and it is possible to contribute to the miniaturization of the panel. ..

If the cooling property and the electric shock suppressing property of the panel are obtained as in the present embodiment, the stationary induction device can be operated safely.

In Examples 1 to 3, detailed description will be omitted as appropriate, for example, by applying the same reference numerals to overlapping contents.

<< Example 1 >>
The schematic explanatory views of FIGS. 1 and 2 illustrate the cooling structure of the panel 10A according to the first embodiment. The board 10A has a board body 1 in which a plurality of board members (for example, a board panel, a columnar frame, a bracket, etc.) are assembled in a housing shape. Then, from the board front portion 11a, which is one side of the board main body 1 (board front portion 11a, board back portion 11b, board right side surface portion 11c, board left side surface portion 11d), the stationary guidance device It has a structure that can accommodate 2 in and out freely.

Further, as shown in FIG. 2, in a state where the stationary guidance device 2 is housed in the board body 1 (hereinafter, simply referred to as a device housed state), a protective cover 6 is provided between the board front portion 11a and the static guidance device 2.

The opening / closing door 14 is provided with intake ports 31 (four intake ports 31 in FIG. 1) that communicate with the intake port side space 71 in the panel body 1, for example, when the ventilator 33 described later is operated. In addition, the structure is such that the air outside the panel body 1 can be taken into the panel body 1.

An air filter 30 for purifying the air taken in from the intake port 31 (for example, removing dust in the air) is provided at the intake port 31 (inside the panel body 1 of the intake port 31 in FIG. 2).

The panel ceiling portion 13 of the panel body 1 is a ventilator 33 having an exhaust port 32 (two exhaust ports 32 in FIG. 1) communicating with the static induction device side space portion 72 in the panel body 1 and a fan 33a. And are provided, and the structure is such that the air inside the panel body 1 can be exhausted to the outside of the panel body 1.

The board bottom 12 side in the board body 1 is provided so that the support rails 4a and 4b extend in the device entry / exit direction (in FIG. 2, the support rails 4a and 4b are laid on the inner side surface of the board bottom 12). The structure is such that the stationary guidance device 2 can be supported via the wheel portions 5 mounted on the rails 4a and 4b.

The support rails 4a and 4b each have a hollow portion 41 extending in the in / out direction on the axial center side. Further, an intake port side through hole 44 is provided on the intake port side space portion 71 side of the outer surface 40 of the support rails 4a and 4b so as to communicate with the hollow portion 41.

The wheel portion 5 has wheels 5a and 5b that roll in the entry / exit direction on the support rails 4a and 4b, respectively, and can be guided and moved by the support rails 4a and 4b while supporting the stationary guidance device 2. It has a structure.

The board 10A shown above is not limited to the configurations shown in FIGS. 1 and 2, and the design can be appropriately modified.

For example, the opening / closing door 14 only needs to be able to open / close the opening 14a and take in / out the stationary guidance device 2, and various aspects can be appropriately applied. Specific examples include those having a double-door structure as shown in FIG. 1 and those having a single-door structure.

Further, the intake port 31 and the exhaust port 32 shown in FIG. 1 are drawn in a rectangular shape by dotted lines for convenience, but each of them communicates with the inside of the panel body 1 so as not to hinder the movement of air. However, various aspects can be appropriately applied. As a specific example, there is an embodiment in which one or more holes such as a slit shape, a circular shape, and a rectangular shape are formed.

Further, the intake port 31 may be provided on the outer peripheral side portion 11ab of the opening / closing door 14 on the panel front portion 11a. The air filter 30 may be provided inside the panel body 1 at the intake port 31 or may be provided outside the panel body 1.

Further, the support rails 4a and 4b can movably support the static guidance device 2 via the wheel portion 5, and the through hole 44 on the intake port side and the through hole 45 on the static guidance device side are connected via the hollow portion 41. As long as the structure is in communication, various aspects can be appropriately applied. As a specific example, as shown in FIG. 2, the tubular structure has a rectangular cross section and extends in the entry / exit direction, and the ends of the support rails 4a and 4b on the board front portion 11a side are opened (in the board 10C described later). Examples thereof include a mode in which the through hole 44 on the intake port side is opened) and a mode in which the reinforcing frame 41a is provided on the axial center side.

The intake port side through hole 44 and the stationary guidance device side through hole 45 shown in FIG. 2 are provided on the side side 43 of the outer surface 40, and each communicate with the hollow portion 41 so as not to hinder the movement of air. As long as it is in the above mode, it may be provided as appropriate in addition to the side 43. As a specific example, it may be provided on the upper side surface 42 or the like, but it is preferable to provide the wheels 5a and 5b so as to avoid the raceway surface 46. Further, as the shape of the through hole 44 on the intake port side and the through hole 45 on the stationary induction device side, there is an embodiment in which one or more holes such as a slit shape, a circular shape, and a rectangular shape are formed.

Further, the positions where the exhaust port 32 and the through hole 45 on the static guidance device side are provided can be appropriately set in consideration of efficiently cooling the static guidance device 2. In the case of FIG. 2, the exhaust port 32 is provided at a position facing the upper side of the stationary guidance device 2 on the panel ceiling portion 13, and the stationary guidance device side through hole 45 is the stationary guidance device 2 on the support rails 4a and 4b. It is provided at a position facing the lower side.

The protective cover 6 is drawn by a chain line for convenience in FIG. 2, but is detachably interposed between the front panel 11a and the stationary guidance device 2 in the device housing state, and the space 7 is provided. It can be appropriately applied as long as it can be classified into the air intake port side space portion 71 and the static induction device side space portion 72. As a specific example, an insulating material or the like is formed into a flat plate shape, and as shown in FIG. 2, between the board front portion 11a and the stationary guidance device 2 in a posture extending in the board standing direction. An embodiment in which intervention (removable intervention) is possible can be mentioned. Further, in order not to interfere with the support rails 4a, 4b and the like, a notch 61 may be formed on the bottom 12 side of the protective cover 6.

Next, an example of the cooling operation of the panel 10A will be described with reference to FIG. First, when the inside of the panel body 1 becomes negative pressure due to the operation of the ventilator 33, the air around the outside of the intake port 31 is sucked into the intake port side space 71 via the intake port 31 as shown by the arrow y1. .. The air taken into the intake port side space 71 moves to the hollow portion 41 through the intake port side through hole 44 as shown by the arrow y2.

The air in the hollow portion 41 moves to the static guidance device side space 72 through the static guidance device side through hole 45, and then rises along the static guidance device 2 as shown by arrow y3 (outside the static guidance device 2). The heat of the stationary induction device 2 is absorbed while rising along the side surface and the gap between the iron core 2a and the winding 2b). The air that has absorbed this heat is exhausted to the outside of the panel 10A via the exhaust port 32 and the ventilator 33.

According to the panel 10A of the first embodiment as described above, as compared with the conventional cooling structure, the cooling structure is simplified and it is easy to suppress the pressure loss, and the desired cooling property, electric shock suppressing property, maintainability and the like can be obtained. It turns out that it is easy to obtain. It can also be seen that it can contribute to miniaturization, design diversification, cost reduction, etc. of the board.

<< Example 2 >>
The schematic explanatory view of FIG. 3 illustrates the cooling structure of the panel 10B according to the second embodiment. The board 10B has a configuration in which the board 10A is appropriately modified, and the main differences are that the support rails 4a and 4b are not provided with the intake port side through hole 44 and the static induction device side through hole 45. The point is that the covering portion 8 is provided so as to cover the gauge space portion 83 between the support rails 4a and 4b.

The covering portion 8 is provided with an intake port side through hole 81 on the outer surface 80 on the intake port side space portion 71 side so as to communicate with the gauge space portion 83. Further, a through hole 82 on the static guidance device side is provided on the outer surface 80 on the static guidance device side space 72 side so as to communicate with the gauge space 83.

The covering portion 8 has a structure in which the gauge space portion 83 is covered and both the intake port side through hole 81 and the stationary induction device side through hole 82 communicate with each other via the gauge space portion 83. It is possible to appropriately apply the aspect of. For example, as shown in FIG. 3, when the device entry / exit direction side of the gauge space portion 83 is covered by the board front portion 11a and the board back portion 11b, an aspect of closing the upper side of the gauge space portion 83 is applied. Just do it. As a specific example, as shown in FIG. 3, a flat plate shape extending in the direction between the support rails 4a and 4b and capable of being supported on each upper side surface 42 of the support rails 4a and 4b can be mentioned.

Further, the shape of the through hole 81 on the intake port side and the through hole 82 on the stationary induction device side may be an embodiment in which one or more holes such as a slit shape, a circular shape, and a rectangular shape are formed.

Further, in the covering portion 8, a material (insulating material or the like) similar to that of the protective cover 6 may be applied, or the covering portion 8 may be coupled to and integrated with the protective cover 6.

Next, an example of the cooling operation of the panel 10B will be described with reference to FIG. First, when the inside of the panel body 1 becomes negative pressure due to the operation of the ventilator 33, the air around the outside of the intake port 31 is sucked into the intake port side space 71 via the intake port 31 as shown by the arrow y1. .. The air taken into the intake port side space 71 moves to the gauge space 83 through the intake port side through hole 81 as shown by the arrow y21.

The air in the gauge space 83 moves to the static guidance device side space 72 through the static guidance device side through hole 82, and then rises along the static guidance device 2 as shown by the arrow y3. It absorbs the heat of 2. The air that has absorbed this heat is exhausted to the outside of the panel 10B via the exhaust port 32 and the ventilator 33.

According to the board 10B of the second embodiment as described above, in addition to exhibiting the same action and effect as that of the first embodiment, the following can be said. That is, since it is not necessary to provide the intake port side through hole 44 and the static induction device side through hole 45 in the support rails 4a and 4b, the mechanical strength is increased, and the support rails 4a and 4b are downsized and the design is diversified. ， May contribute to cost reduction.

Further, since the covering portion 8 does not require mechanical strength like the support rails 4a and 4b, for example, the through hole 81 on the intake port side and the through hole 82 on the stationary induction device side can be made into a relatively large shape. Become. As a result, it can be seen that the pressure loss in the panel body 1 can be suppressed and the desired cooling property and the like can be easily obtained.

<< Example 3 >>
The schematic explanatory views of FIGS. 4 to 6 illustrate the cooling structure of the panel 10C according to the third embodiment. The board 10C has a configuration in which the board 10A is appropriately modified, and the main differences are that the intake port 31 is provided at a position facing the support rails 4a and 4b on the board front portion 11a and the outer surface 40. The point is that the intake port side through hole 44 is provided at a position facing the intake port 31 on the intake port side space portion 71 side of the above.

In the case of the board 10C shown in FIG. 4, the lower side of the outer peripheral side portion 11ab of the board front portion 11a faces the support rails 4a and 4b, and the intake port 31 is provided at the facing position. When the shape of the opening / closing door 14 is relatively large and the lower side of the opening / closing door 14 faces the support rails 4a and 4b as in the board 10C shown in FIG. 6, the intake port 31 is located at the facing position. Should be provided.

Next, an example of the cooling operation of the panel 10C will be described with reference to FIG. First, when the inside of the panel body 1 becomes negative pressure due to the operation of the ventilator 33, the air around the outside of the intake port 31 passes through the intake port 31 and the intake port side through hole 44 as shown by the arrow y11. Is inhaled to.

The air in the hollow portion 41 moves to the static guidance device side space portion 72 through the static guidance device side through hole 45, and then rises along the static guidance device 2 as shown by the arrow y3. Absorbs the heat of. The air that has absorbed this heat is exhausted to the outside of the panel 10C via the exhaust port 32 and the ventilator 33.

According to the board 10C of Example 3 as described above, in addition to exhibiting the same action and effect as that of Example 1, the following can be said. That is, since the movement path of the air taken in from the intake port 31 is shortened (the movement of the arrow y2 in FIG. 2 is omitted), the pressure loss in the panel body 1 can be suppressed, and the desired cooling property and the like can be easily obtained. I understand.

Although the above description has been made in detail only with respect to the specific examples described in the present invention, it is clear to those skilled in the art that various changes and the like can be made within the scope of the technical idea of the present invention. It goes without saying that such changes belong to the scope of claims.

For example, in the board 10B, the intake port 31 can be appropriately deformed in the same manner as in the third embodiment, and the intake port 31 is provided at a position facing the gauge space portion 83 in the board front portion 11a (for example, the position of reference numeral 11ac in FIG. 4). It may be provided so that the intake port side through hole 81 is provided at a position facing the intake port 31 on the outer surface 80 of the covering portion 8. Even when the board 10B is appropriately deformed in this way, it is possible to obtain the same effects as in the third embodiment.

Further, in the boards 10A to 10C, for example, as shown in FIGS. ), And the protective cover 6 may be interposed between the board front portion 11a and the stationary guidance device 2. Even in the configurations of FIGS. 7 (A) to 7 (C), it is possible to obtain the same effects as in Examples 1 to 3, respectively. Further, since the stationary guidance device 2 can be taken in and out from the front surface portion 11a of the panel without making the protective cover 6 removable, the cooling structure becomes simpler, and there is a possibility that maintainability and the like can be easily obtained. be.
