凸部１２ｆ，１２ｇは、一対の支持部材１１の孔１１ｃに入れられている。具体的には、凸部１２ｆは、支持部材１１Ａの孔１１ｃに入れられ（図４）、凸部１２ｇは、支持部材１１Ｂの孔１１ｃに入れられている。凸部１２ｆ，１２ｇと筒状面１１ｄとは、互いに引っ掛かっている。この状態では、筒状面１１ｄによって、凸部１２ｆ，１２ｇひいてはルーバー１２が、一対の支持部材１１に対して回り止めされる。そして、この状態で、ルーバー１２が、一対の支持部材１１Ａ，１１Ｂによって支持される。 The convex portions 12f and 12g are inserted into the holes 11c of the pair of support members 11. Specifically, the convex portion 12f is inserted into the hole 11c of the support member 11A (FIG. 4), and the convex portion 12g is inserted into the hole 11c of the support member 11B. The convex portions 12f and 12g and the tubular surface 11d are caught on each other. In this state, the tubular surface 11d prevents the convex portions 12f, 12g and thus the louver 12 from rotating with respect to the pair of support members 11. Then, in this state, the louver 12 is supported by the pair of support members 11A and 11B.

図２〜５から分かるように、一対の塞ぎ部材１３は、複数のルーバー１２のうち交差方向Ｄ２の端（両端）に位置したルーバー１２と扉８（筐体２）との間に設けられ、当該ルーバー１２と扉８との間を塞いでいる。塞ぎ部材１３は、板状に構成されている。各塞ぎ部材１３は、互いに積層されて互いに結合された複数の板部材１３ａを有している。塞ぎ部材１３は、扉８の内面８ｄに、ネジなどの結合具によって結合（固定）されている。 As can be seen from FIGS. 2 to 5, the pair of closing members 13 are provided between the louvers 12 located at the ends (both ends) of the crossing direction D2 and the door 8 (housing 2) among the plurality of louvers 12. The space between the louver 12 and the door 8 is blocked. The closing member 13 is formed in a plate shape. Each closing member 13 has a plurality of plate members 13a that are laminated and connected to each other. The closing member 13 is connected (fixed) to the inner surface 8d of the door 8 by a connecting tool such as a screw.

上記構成では、スイッチギヤ１が正常の場合には、換気装置３の各ルーバー１２が開姿勢となっている（図４）。このとき、隣り合うルーバー１２間の隙間Ｓ（通気路）が扉８の開口部８ｃと連通している。この状態では、隣り合うルーバー１２間の隙間Ｓを介して、筐体２の換気（通気）が行われたり、筐体２内の熱が筐体２外に放出される。一方、異常等によって筐体２内で高温や高圧のガスが生じて筐体２内の圧力が増加すると、ルーバー１２の板状部１２ｃが、隙間Ｓが無くなるようにすなわち開口部８ｃに近づくように変形する。当該変形により、ルーバー１２は、当該ルーバー１２の隣りのルーバー１２または塞ぎ部材１３と接触した状態で当該隣りのルーバー１２または塞ぎ部材１３と重なる（図５）。これにより、複数のルーバー１２によって開口部８ｃが閉じられた状態となる。以上のように、本実施形態では、隣り合う二つのルーバー１２は、筐体２内の圧力の増加に伴って変形し、互いに接触した状態で重なる（図５）。これにより、発生したガスが、開口部８ｃから筐体２の外部に噴出するのが抑制される。 In the above configuration, when the switchgear 1 is normal, each louver 12 of the ventilation device 3 is in the open posture (FIG. 4). At this time, the gap S (ventilation path) between the adjacent louvers 12 communicates with the opening 8c of the door 8. In this state, the housing 2 is ventilated (ventilated) through the gap S between the adjacent louvers 12, and the heat inside the housing 2 is released to the outside of the housing 2. On the other hand, when a high-temperature or high-pressure gas is generated in the housing 2 due to an abnormality or the like and the pressure in the housing 2 increases, the plate-shaped portion 12c of the louver 12 approaches the opening 8c so that the gap S disappears. Transforms into. Due to the deformation, the louver 12 overlaps with the adjacent louver 12 or the closing member 13 in contact with the adjacent louver 12 or the closing member 13 (FIG. 5). As a result, the opening 8c is closed by the plurality of louvers 12. As described above, in the present embodiment, the two adjacent louvers 12 are deformed as the pressure inside the housing 2 increases, and overlap each other in contact with each other (FIG. 5). As a result, the generated gas is suppressed from being ejected from the opening 8c to the outside of the housing 2.

次に、換気装置３の組立方法（取付方法）について説明する。まず、作業者は、一対の支持部材１１に設けられた孔ｃに、ルーバー１２の凸部１２ｆ，１２ｇを入れて、一対の支持部材１１でルーバー１２を挟む。次に、ルーバー１２を挟んだ状態の一対の支持部材１１を、結合具によって扉８に結合する。次に、塞ぎ部材１３を結合具によって扉８に結合する。なお、塞ぎ部材１３を扉８に結合した後に、一対の支持部材１１を結合具によって扉８に結合してもよい。このような、組立方法においては、例えば、溶接作業が不要である。 Next, an assembly method (mounting method) of the ventilation device 3 will be described. First, the operator inserts the convex portions 12f and 12g of the louver 12 into the holes c provided in the pair of support members 11, and sandwiches the louver 12 between the pair of support members 11. Next, the pair of support members 11 sandwiching the louver 12 are joined to the door 8 by a coupling tool. Next, the closing member 13 is connected to the door 8 by the coupling tool. After connecting the closing member 13 to the door 8, the pair of support members 11 may be connected to the door 8 by a coupling tool. In such an assembly method, for example, welding work is unnecessary.

以上のように、本実施形態では、換気装置３は、互いに間隔を空けて並べられ、筐体２に結合される一対の支持部材１１と、一対の支持部材１１の間に位置し、筐体２に設けられた開口部８ｃを開閉するルーバー１２と、を備えている。また、一対の支持部材１１のそれぞれと一対の支持部材１１の並び方向Ｄ１におけるルーバー１２の両端部１２ａ，１２ｂとの一方（一例として、ルーバー１２の両端部１２ａ，１２ｂ）に、凸部１２ｆ，１２ｇが設けられている。また、一対の支持部材１１Ａ，１１Ｂのそれぞれと両端部１２ａ，１２ｂとの他方（一例として、一対の支持部材１１Ａ，１１Ｂ）に、凸部１２ｆ，１２ｇが入れられた孔１１ｃと孔１１ｃに面した筒状面１１ｄとが設けられている。そして、一対の支持部材１１Ａ，１１Ｂは、凸部１２ｆ，１２ｇと筒状面１１ｄとが引っ掛かった状態で、ルーバー１２を支持する。よって、本実施形態によれば、例えば、孔１１ｃに凸部１２ｆ，１２ｇを入れて、一対の支持部材１１によってルーバー１２を挟んだ状態では、ルーバー１２が一対の支持部材１１に支持されて、一対の支持部材１１から脱落しない。したがって、換気装置３の組み立てがし易い。 As described above, in the present embodiment, the ventilation devices 3 are arranged at intervals from each other and are located between the pair of support members 11 and the housing, which are coupled to the housing 2. It is provided with a louver 12 for opening and closing the opening 8c provided in 2. Further, on one of the pair of support members 11 and both end portions 12a and 12b of the louver 12 in the arrangement direction D1 of the pair of support members 11 (for example, both end portions 12a and 12b of the louver 12), convex portions 12f, 12 g is provided. Further, on the other side of the pair of support members 11A and 11B and both end portions 12a and 12b (for example, the pair of support members 11A and 11B), the convex portions 12f and 12g are formed in the holes 11c and the holes 11c. A cylindrical surface 11d is provided. Then, the pair of support members 11A and 11B support the louver 12 in a state where the convex portions 12f and 12g and the tubular surface 11d are caught. Therefore, according to the present embodiment, for example, in a state where the convex portions 12f and 12g are inserted in the holes 11c and the louvers 12 are sandwiched between the pair of support members 11, the louvers 12 are supported by the pair of support members 11. It does not fall off from the pair of support members 11. Therefore, the ventilation device 3 can be easily assembled.

また、本実施形態では、孔１１ｃに凸部１２ｆ，１２ｇが入れられているので、一対の支持部材１１に対するルーバー１２の位置合わせが正確に行われる。これにより、一対の支持部材１１に対するルーバー１２の位置調整を不要とすることができる。 Further, in the present embodiment, since the convex portions 12f and 12g are formed in the holes 11c, the louvers 12 are accurately aligned with each other with respect to the pair of support members 11. This makes it unnecessary to adjust the position of the louver 12 with respect to the pair of support members 11.

また、本実施形態では、換気装置３は、並び方向Ｄ１と交差する交差方向Ｄ２に並べられた複数のルーバー１２と、複数のルーバー１２のうち交差方向Ｄ２の端に位置したルーバー１２と筐体２との間を塞ぐ塞ぎ部材１３と、を備えている。よって、本実施形態によれば、例えば、複数のルーバー１２のうち交差方向Ｄ２の端に位置したルーバー１２と筐体２との間からガスが流出するのを塞ぎ部材１３によって抑制することができる。 Further, in the present embodiment, the ventilation device 3 includes a plurality of louvers 12 arranged in the intersection direction D2 intersecting the arrangement direction D1, and a louver 12 and a housing located at the end of the intersection direction D2 among the plurality of louvers 12.

Therefore, according to the present embodiment, for example, the outflow of gas from between the louver 12 located at the end of the crossing direction D2 and the housing 2 among the plurality of louvers 12 can be suppressed by the blocking member 13. ..

また、本実施形態では、隣り合う二つのルーバー１２は、筐体２内の圧力の増加に伴って変形し、互いに接触した状態で重なる。よって、本実施形態によれば、例えば、筐体２の圧力が増加した際に、隣り合うルーバー１２間からガスが流出するのを抑制することができる。 Further, in the present embodiment, the two adjacent louvers 12 are deformed as the pressure inside the housing 2 increases, and overlap each other in contact with each other. Therefore, according to the present embodiment, for example, when the pressure of the housing 2 increases, it is possible to suppress the outflow of gas from the adjacent louvers 12.

また、本実施形態では、板状部１２ｃの厚さは、例えば、２ｍｍ程度である。よって、筐体２内の圧力増加によって、板状部１２ｃが変形し易い。 Further, in the present embodiment, the thickness of the plate-shaped portion 12c is, for example, about 2 mm. Therefore, the plate-shaped portion 12c is easily deformed due to the increase in pressure inside the housing 2.

なお、本実施形態では、一対の支持部材１１Ａ，１１Ｂのそれぞれに、孔１１ｃおよび筒状面１１ｄが設けられ、ルーバー１２の両端部１２ａ，１２ｂに、凸部１２ｆ，１２ｇが設けられた構成が例示されたが、これに限られない。すなわち、一対の支持部材１１Ａ，１１Ｂのそれぞれに、凸部１２ｆ，１２ｇが設けられ、ルーバー１２の両端部１２ａ，１２ｂに孔１１ｃおよび筒状面１１ｄが設けられていてもよい。 In the present embodiment, the pair of support members 11A and 11B are provided with holes 11c and tubular surfaces 11d, respectively, and the louvers 12 are provided with convex portions 12f and 12g at both end portions 12a and 12b.
