It has a function to prevent leakage. Thus, the container 2, the guide plate support 4, the cushion material 5, and the guide plate 6 are airtight. Hereinafter, in the container 2, the lower part of the guide plate 6 is referred to as a lower chamber 2a, and the upper part of the guide plate 6 is referred to as an upper chamber 2b. The container 2 is divided into a lower chamber 2a and an upper chamber 2b by a guide plate 6.

  As shown in FIG. 2, the transformer 1 is a cooler connected via an upper communication path 18 provided in the upper chamber 2 b of the container 2 and a lower communication path 20 provided in the lower chamber 2 a of the container 2. 16 is provided. The cooler 16 is a heat exchanger and has a function of cooling a cooling medium sealed in the cooler 16. With the upper communication path 18 and the lower communication path 20, the cooling medium in the container 2 can communicate with the cooler 16. The cooling medium heated in the winding 12 passes through the upper communication path 18 from the upper chamber 2 b and enters the cooler 16. After being cooled by the cooler 16, the cooling medium immediately after cooling passes through the lower communication path 20. Then, it flows into the lower chamber 2a of the container 2. A blower 22 is provided in the lower communication path 20. The blower 22 allows the cooling medium in the cooler 16 to be efficiently blown and transported to the lower chamber 2a. The inside of the container 2 and the cooler 16 connected to the container 2 via the upper communication path 18 and the lower communication path 20 are configured to be airtight. The cooling medium is enclosed in the container 2 and the cooler 16 at a pressure exceeding atmospheric pressure. The cooling performance can be improved by increasing the pressure of the cooling medium sealed inside. Air is used as the cooling medium. This facilitates operations such as pressure reduction in the container 2, entry into the container 2, and re-encapsulation of the cooling medium during maintenance of the transformer 1 and the like. Accordingly, maintenance work such as inspection and repair of the transformer 1 is facilitated.

  As shown in FIGS. 3 and 4, the guide plate 6 is a rectangular flat plate member. The outer periphery of the guide plate 6 is configured to overlap the inner edge portion of the guide plate support 4, and the guide plate support 4 and the guide plate 6 are connected by narrowing the cushion material 5 in the overlapping portion. . The guide plate 6 is provided with an opening 6a configured to correspond to the shape of the winding 12 so as to correspond to a position directly below the winding 12, in this case, an opening 6a that is a substantially circular window. It has been. In the installed state of the transformer 1, the iron core 10 passes through the opening 6a. The size of the opening 6 a is configured to be slightly larger than the outer diameter of the winding 12 so that the cooling medium flows through the outer wall of the winding 12. The container 2, the guide plate support 4, the cushion material 5, and the guide plate 6 are airtight except for the opening 6 a, and the container 2, the guide plate support 4, the cushion material 5, and the guide plate 6 are between them. Then, there is no gas leakage.

  As shown in FIGS. 1 and 2, the blower 14 is disposed so as to be located immediately below the winding 12. That is, the blower 14 is disposed so as to be located immediately below the opening 6 a of the guide plate 6. The blower 14 is disposed in the lower part of the container 2, that is, in the lower chamber 2a. The blower 14 moves the cooling medium immediately after being cooled by the cooler 16 from below to above. The opening 6a, the winding 12 and the in-winding flow path 13 are located directly above the blower 14. The cooling medium is blown upward by the blower 14, passes through the opening 6 a of the guide plate 6, and blows so as to mainly pass through the winding inner flow path 13, the inner wall 12 a and the outer wall 12 b of the winding 12. Is done. In this way, the flow of the cooling medium created by the blower 14 is directed to efficiently travel in the direction of the winding 12 by the opening 6a, and the flow path 13 in the winding, the inner wall 12a of the winding 12 and the outside It passes through the wall 12b. In addition, although the air blower 14 shown by FIG.1 and FIG.2 seems to be arrange | positioned only from right and left front and back, front and back of the iron core 10 from the relationship of a cross-sectional position, you may arrange | position also in the position which is not shown by a cross section. . In other words, the blower 14 may be arranged as many as the installation location allows.

  Further, the flow of the cooling medium generated by the blower 14 can be concentrated in the direction of the winding 12 by the guide plate 6 having the opening 6a as described above and the blower 14 provided immediately below the opening 6a. it can. That is, since the cooling medium can be concentrated in the direction of the inner flow path 13, the inner wall 12 a of the winding 12 (that is, the gap between the winding 12 and the iron core 10) and the outer wall 12 b, the cooling medium can be blown. 12 can be efficiently cooled.

  Further, by the blower 14 and the blower 22, a path such as the lower chamber 2a → the winding 12, that is, the flow path 13 in the winding → the upper chamber 2b → the upper communication path 18 → the cooler 16 → the lower communication path 20 → the lower chamber 2a. A circulation path of the cooling medium that circulates in is formed.

The static induction device according to the first embodiment has the following effects.
A guide plate 6 having an opening 6a provided so as to be positioned below the winding 12 and a blower 14 are disposed so as to be positioned below the opening 6a, preferably directly below. The cooling medium is blown upward by the blower 14, that is, in the direction of the winding 12. The winding 12 is provided with an in-winding passage 13 through which the cooling medium passes. The opening 6 a is configured to open slightly larger than the outer diameter of the winding 12. With this configuration, the cooling medium can be blown in a concentrated manner in the direction of the inner flow path 13 of the winding 12, the inner wall 12a and the outer wall 12b of the winding 12, so that the cooling efficiency of the winding 12 is improved. Can be improved.

  The container 2 is divided into a lower chamber 2a and an upper chamber 2b by a guide plate 6. The cooling medium cooled by the cooler 16 is blown into the lower chamber 2 a, and the cooled cooling medium can be blown in the direction of the winding 12 by the blower 14. The cooling medium warmed by cooling the winding 12 is sent to the upper chamber 2b. The cooling medium in the upper chamber 2 b is sent to the cooler 16 through the upper communication path 18 and is cooled by the cooler 16. With this configuration, the cooling medium immediately after being cooled does not mix with the cooling medium warmed by the winding 12. For this reason, since the cooling medium with a low temperature can be efficiently blown to the winding 12, the cooling efficiency of the winding 12 can be improved.

  The lower communication passage 20 communicating with the lower chamber 2a of the container 2 is provided with a blower 22. Thereby, the cooling medium immediately after being cooled by the cooler 16 can be efficiently blown to the lower chamber 2a. The lower chamber 2a is provided with a plurality of blowers 14 with the blowing direction set to the upper direction, that is, the winding 12 direction. Thereby, the cooling medium cooled by the cooler 16 is blown to the lower chamber 2 a by the blower 22, and the cooled cooling medium is blown by the blower 14 in the direction of the winding 12, that is, the flow path 13 in the winding and the inside of the winding 12. The air is concentrated in the direction of the wall 12a and the outer wall 12b. Thus, the cooling immediately after being cooled by the blower 22 that blows the cooling medium cooled by the cooler 16 to the lower chamber 2a and the blower 14 that is arranged in the lower chamber 2a and blows the cooling medium in the direction of the winding 12. Since the medium can be efficiently blown in the direction of the winding 12 to be cooled, the winding 12 can be efficiently cooled. For this reason, the cooling efficiency of the winding 12 can be improved. In this case, if a plurality of lower communication passages 20 and a plurality of blowers 22 are provided, the cooling efficiency of the winding 12 can be further improved. Further, since the cooling medium is promoted by the blower 14 and the blower 22, the cooling efficiency of the winding 12 can be improved also by this.

  The guide plate 6 is fixed to a guide plate support 4 fixed to the inner wall of the container 2 via a cushion material 5. In this case, the cushion material 5 has a function of filling the gap between the guide plate support 4 and the guide plate 6 and preventing the cooling medium from leaking between the guide plate support 4 and the guide plate 6. With this configuration, the cooling medium immediately after being cooled and transported by being blown from the cooler 16 to the lower chamber 2a does not leak, and the loss of the cooling medium immediately after cooling that is blown in the direction of the winding 12 is suppressed. be able to. For this reason, the fall of the cooling efficiency of the coil | winding 12 can be suppressed.

  Further, the cooling medium has a low density when the temperature is high, and the density becomes high when the temperature is low. Therefore, even when the blower 14 and the blower 22 are stopped, convection occurs due to the density difference due to the temperature of the cooling medium cooled by the cooler 16, and thus the cooling medium circulates in the circulation path. Thereby, even when the blower 14 and the blower 22 are stopped, the winding 12 is cooled by the convection generated by the cooler 16. Also in this case, since the cooling medium flows intensively in the direction of the winding 12 positioned immediately above the opening 6a, the cooling medium is concentrated on the winding inner flow path 13, the inner wall 12a, and the outer wall 12b. Can be blown into. For this reason, even when the blower 14 and the blower 22 are stopped, the cooling efficiency of the winding 12 can be improved.

(Second Embodiment)
Next, a second embodiment will be described. FIG. 5 is a plan view showing a schematic configuration of a modified example of the guide plate 6. In the second embodiment, the guide plate 6 located immediately below the winding 12 is provided with slits 70 directed to the in-winding flow path 13 and the outer wall 12b.

The slit part 70 is arrange | positioned at four fan-shaped area | regions of the angle range of about 90 degree | times, for example. The slits 70 are arranged in the order of the slits 71, 72, 73, 74 from the side closer to the opening 61. Each slit part 70 is arrange | positioned so that it may adjoin to the circumferential direction via the bridge part 8 provided in the boundary area | region of a sector area. The slit portions 70 are arranged concentrically and constitute four annular slits divided by the bridge portion 8.

  With the guide plate 60 installed in the transformer 1, the guide plate 60 is disposed directly below the winding 12. In this case, the opening 61 has an inner diameter that allows the iron core 10 to pass therethrough, and the opening 61 is installed through the iron core 10. Further, in this case, the three slit portions 71, 72, 73 from the inside are arranged at positions immediately below the respective in-winding passages 13 of the winding 12 in correspondence with the arrangement of the in-winding passages 13. The outermost slit portion 74 is disposed so as to be located slightly outside the outer wall 12 b of the winding 12.

  The blower 14 is disposed below the guide plate 60, and the cooling medium is blown upward by the blower 14. Therefore, the cooling medium blown by the blower 14 is a slit located directly below the flow path 13 in the winding. The air passes through the portion 70 and is intensively blown toward the in-winding flow path 13 and the outer wall 12b. In addition, the cooling medium that has passed through the opening 61 passes through the gap between the iron core 10 and the inner wall 12 a of the winding 12, so that it is blown and transported to the inner wall 12 a of the winding 12.

Other configurations are the same as those of the transformer 1 according to the first embodiment.
According to the transformer 1 using the guide plate 60 according to the second embodiment, in addition to the same effects as those of the first embodiment, the following effects can be obtained.

  The slit portions 70 (71, 72, 73, 74) provided in the guide plate 60 are formed on the inner passage 13 and the outer wall 12b of the winding 12 in a state where the guide plate 60 is installed in the transformer 1. It is comprised so that it may be in a directly lower position. Moreover, the opening part 61 is arrange | positioned in the position just under the gap | interval between the iron core 10 and the inner wall 12a. Therefore, as a result of the cooling medium being blown upward by the blower 14, the cooling medium is intensively blown and transported toward the in-winding flow path 13, the inner wall 12 a, and the outer wall 12 b of the winding 12. In this way, the cooling medium immediately after cooling in the lower chamber 2a of the container 2 is concentrated and blown in the direction of the winding 12, that is, the flow path 13 in the winding, the inner wall 12a and the outer wall 12b of the winding 12. Therefore, the cooling efficiency of the winding 12 can be improved.

  Further, according to this configuration, the cooling medium that has passed through the slit portion 70 and the opening 61 of the guide plate 60 is not blown toward the bottom portion of the winding 12 or the like. Therefore, since the cooling medium sent by the blower 14 does not flow toward the structure that obstructs the flow of the cooling medium, the blowing efficiency does not decrease. Therefore, the cooling efficiency of the winding 12 can be improved.
