実公平１−１３４７０号公報（第１頁、第３図）Japanese Utility Model Publication No. 1-1470 (1st page, FIG. 3)

上記のような従来技術による屋外形配電盤は、太陽熱等の外部輻射熱に対して、シールド効果を大きくし、過酷な環境条件に適用できるとはいうものの、内部に収容された機器からの発熱が大きい場合などにおいては、外気温度や太陽光などの悪条件が重なったときに筺体内部の温度が望ましい限度を超える程度に上昇し、収納機器の寿命や信頼性に影響が出るという問題があった。   Although the above-mentioned outdoor type switchboard according to the conventional technology has a large shielding effect against external radiant heat such as solar heat and can be applied to harsh environmental conditions, it generates a large amount of heat from the equipment housed inside. In some cases, when adverse conditions such as outside air temperature and sunlight overlap, the temperature inside the housing rises to a level that exceeds a desired limit, which affects the life and reliability of the storage device.

この発明は上記のような実情に鑑みてなされたもので、収容機器からの発熱や過酷な温度条件に晒されても筺体内部の温度上昇が抑制され収納機器の寿命や信頼性を確保できる屋外形配電盤を得ることを目的としている。   The present invention has been made in view of the above circumstances, and is capable of suppressing the rise in temperature inside the housing even when exposed to heat generation from the storage device or severe temperature conditions, and ensuring the life and reliability of the storage device. The purpose is to obtain an external switchboard.

この発明に係る屋外形配電盤は、機器が収容され天井部に通気口を有する筺体と、上記筺体の天井部に該筺体に対して回動可能に設けられ、閉じたときに上記天井部を塞ぎ、開いたときに上記天井部を開放する天井開閉ユニットと、この天井開閉ユニットを開閉させる駆動装置と、上記筺体内部の温度を検知する温度センサと、この温度センサの検知結果に応じて上記駆動装置を制御する制御装置とを備えるようにしたものである。   An outdoor type switchboard according to the present invention is provided with a housing in which equipment is housed and having a ventilation hole in a ceiling portion, and is provided on the ceiling portion of the housing so as to be rotatable with respect to the housing, and closes the ceiling portion when closed. A ceiling opening / closing unit that opens the ceiling when opened, a driving device that opens / closes the ceiling opening / closing unit, a temperature sensor that detects the temperature inside the housing, and the driving according to a detection result of the temperature sensor. And a control device for controlling the device.

この発明においては、筺体内部の温度が高くなると、温度センサがそれを検知して天井開閉ユニットを開いて、筺体内部の熱を筺体の天井部から逃がすようにしたので、太陽光による熱や収容された機器の発熱による筺体内部の温度上昇が抑制され収納機器の寿命や信頼性を確保できる。   In this invention, when the temperature inside the enclosure becomes high, the temperature sensor detects it and opens the ceiling opening / closing unit so that the heat inside the enclosure is released from the ceiling of the enclosure. The temperature rise inside the housing due to the heat generated by the device is suppressed, and the life and reliability of the storage device can be secured.

実施の形態１．
以下、本発明の実施の形態１に係る屋外形配電盤について図面を参照して説明する。実施の形態１に係る屋外形配電盤は、図１の側面図に示すように、電気回路を開閉するための開閉機器や制御回路など、何れも図示省略している各種機器が収容された筺体１と、この筺体１の天井部２に回動可能に設けられ、太陽光の反射率が高い遮熱塗料が塗布された天井開閉ユニット３と、天井開閉ユニット３を開閉動作させる駆動装置４と、筺体１の内部の上方部に設置された筺体１の内部の温度を検知する温度センサ５と、この温度センサ５の出力に応じて駆動装置４を制御する制御装置６などを用いて構成されている。なお、この例では図１の左側が前面部である。筺体１の背面側には鎧状の通気口１ａが設けられている。通気口１ａの内側には、虫などの異物の侵入を防ぐ図示省略しているフィルタが設置されている。 Embodiment 1 FIG.
Hereinafter, an outdoor type switchboard according to Embodiment 1 of the present invention will be described with reference to the drawings. As shown in the side view of FIG. 1, the outdoor type switchboard according to Embodiment 1 includes a housing 1 in which various devices, such as an open / close device and a control circuit for opening and closing an electric circuit, are omitted. A ceiling opening / closing unit 3 that is rotatably provided on the ceiling portion 2 of the housing 1 and is coated with a heat-shielding paint having a high solar reflectance, and a driving device 4 that opens and closes the ceiling opening / closing unit 3. It is configured using a temperature sensor 5 that detects the temperature inside the housing 1 installed in the upper part inside the housing 1, and a control device 6 that controls the driving device 4 in accordance with the output of the temperature sensor 5. Yes. In this example, the left side of FIG. An armor-shaped air vent 1 a is provided on the back side of the housing 1. A filter (not shown) that prevents entry of foreign matters such as insects is installed inside the vent 1a.

上記天井開閉ユニット３は、閉じた状態で後方側が低くなるような所定の勾配が設けられた屋根状に形成されており、周囲にはそれぞれ前板３ａ、側板３ｂ、及び後板３ｃなどの側板が取り付けられている。前板３ａには天井開閉ユニット３の内部空間を外気に連通させる鎧状の通気口３ｄが設けられており、さらに前板３ａの下部には、異物などの侵入を防ぐカバー板３ｅが固定されている。そして、天井開閉ユニット３は、図２〜図４に示す、左右の側板３ｂの後端部相互を連結する如く設けられた金属製の丸棒状の支軸７ａ（図３）と、筺体１の奥側上端に溶接あるいはボルト等によって固定され、支軸７ａを回動可能に支持する切欠穴が設けられたＬ字形の一対の受金７ｂ（図４）からなるヒンジ７によって、筺体１に対して回動可能に支持されている。   The ceiling opening / closing unit 3 is formed in a roof shape having a predetermined slope so that the rear side is lowered in a closed state, and side plates such as a front plate 3a, a side plate 3b, and a rear plate 3c are provided around the ceiling. Is attached. The front plate 3a is provided with an armor-shaped vent 3d that allows the internal space of the ceiling opening / closing unit 3 to communicate with the outside air, and a cover plate 3e that prevents intrusion of foreign substances and the like is fixed to the lower portion of the front plate 3a. ing. The ceiling opening and closing unit 3 includes a metal round bar-shaped support shaft 7a (FIG. 3) provided so as to connect the rear ends of the left and right side plates 3b shown in FIGS. It is fixed to the housing 1 by a hinge 7 consisting of a pair of L-shaped receiving members 7b (FIG. 4) fixed to the upper end on the back side by welding or bolts and provided with a notch hole for rotatably supporting the support shaft 7a. And is rotatably supported.

なお、上記ヒンジ７は図６〜図８に示す変形例のように構成しても良い。即ち、支軸７ａを図７に示すように、側板３ｂに溶接により固定された短いピン７ｃに変更し、受金７ｂを図８に示すように、切欠穴を丸穴に変更したＬ字形の受金７ｄに変更し、図６に示すように筺体１上に取り付ける。なお、必要に応じてピン７ｃにスナップリングなどを設けて軸方向への移動を規制するようにしても良い。この変形例の場合、ヒンジ７のピン７ｃが受金７ｄの丸穴に係合されているので、天井開閉ユニット３が強風などに対して外れる恐れをなくすことができる。   In addition, you may comprise the said hinge 7 like the modification shown in FIGS. That is, as shown in FIG. 7, the support shaft 7a is changed to a short pin 7c fixed to the side plate 3b by welding, and the metal receiver 7b is changed to a round hole as shown in FIG. It changes to the metal receiver 7d and attaches to the housing 1 as shown in FIG. Note that, if necessary, a snap ring or the like may be provided on the pin 7c to restrict movement in the axial direction. In the case of this modification, since the pin 7c of the hinge 7 is engaged with the round hole of the metal receiver 7d, it is possible to eliminate the possibility that the ceiling opening / closing unit 3 will come off against a strong wind.

図５の斜視図は、天井開閉ユニット３や受金７ｂなどを取り外したときの筺体１の天井部２を示している。筺体１の上端部にはスリット状の複数の通気口８ａを有する天井板８が一体的に固定されている。このため、天井開閉ユニット３が筺体１とは別に形成されていても剛性が保持されるように構成されている。なお、通気口８ａには、虫やごみなどの異物の侵入を防ぐ図示省略しているフィルタが設置されている。また、天井板８の上面部の通気口８ａよりも外側周囲部には、図示省略しているパッキング等のシーリング部材が設けられており、天井開閉ユニット３を閉じたときに該シーリング部材によって天井板８との間の隙間が塞がれるように構成されている。なお、天井開閉ユニット３を閉じたときには、筺体１の通気口３ｄから流入した空気は筺体１内を通って通気口８ａ、天井開閉ユニット３の内部空間、及び通気口３ｄを通って外気に放出される。   The perspective view of FIG. 5 shows the ceiling portion 2 of the casing 1 when the ceiling opening / closing unit 3, the metal receiver 7b, and the like are removed. A ceiling plate 8 having a plurality of slit-shaped vents 8 a is integrally fixed to the upper end portion of the housing 1. For this reason, even if the ceiling opening / closing unit 3 is formed separately from the housing 1, the rigidity is maintained. Note that a filter (not shown) that prevents entry of foreign matters such as insects and dust is installed in the vent hole 8a. Further, a sealing member such as packing (not shown) is provided on the outer peripheral portion of the upper surface portion of the ceiling plate 8 from the vent hole 8a. When the ceiling opening / closing unit 3 is closed, the ceiling member opens the ceiling. The gap between the plate 8 is configured to be closed. When the ceiling opening / closing unit 3 is closed, air flowing from the vent 3d of the casing 1 passes through the casing 1 and is released to the outside air through the vent 8a, the internal space of the ceiling opening / closing unit 3, and the vent 3d. Is done.

上記駆動装置４は、この例では空気を圧縮するコンプレッサ４ａと、筺体１の天井部と天井開閉ユニット３の間に設置され、圧縮空気により膨張して天井開閉ユニット３を押し上げるようにヒンジ７の周りに回動させるバルーン４ｂと、コンプレッサ４ａによって圧縮された空気をバルーン４ｂに送る空気パイプ４ｃと、空気パイプ４ｃの途中に介装された電磁駆動される３方弁４ｄからなっている。   In this example, the driving device 4 is installed between the compressor 4a for compressing air, and the ceiling portion of the casing 1 and the ceiling opening / closing unit 3, and is expanded by the compressed air to push up the ceiling opening / closing unit 3. It consists of a balloon 4b that rotates around, an air pipe 4c that sends the air compressed by the compressor 4a to the balloon 4b, and an electromagnetically driven three-way valve 4d that is interposed in the middle of the air pipe 4c.

制御装置６は、温度センサ５によって検知された筺体１内の温度に対応する信号が所定のレベルを超えたときに３方弁４ｄを、流路が図の上下方向にのみ連通するように切り替えた後、コンプレッサ４ａを駆動させて、空気パイプ４ｃから圧縮空気を所定時間バルーン４ｂに送ってバルーン４ｂを膨張させ、天井開閉ユニット３を予め設定された所定角度開く。一方、温度センサ５によって検知された信号が所定のレベルを下回ると、３方弁４ｄの流路を、バルーン４ｂ側が外気に連通するように切り替えて、バルーン４ｂ内の空気を３方弁４ｄから外部に流出させる。なお、空気圧が消失すると天井開閉ユニット３は自重で下降し、天井板８の通気口８ａを塞ぐ。   When the signal corresponding to the temperature in the housing 1 detected by the temperature sensor 5 exceeds a predetermined level, the control device 6 switches the three-way valve 4d so that the flow path communicates only in the vertical direction in the figure. After that, the compressor 4a is driven, compressed air is sent from the air pipe 4c to the balloon 4b for a predetermined time to inflate the balloon 4b, and the ceiling opening / closing unit 3 is opened at a predetermined angle. On the other hand, when the signal detected by the temperature sensor 5 falls below a predetermined level, the flow path of the three-way valve 4d is switched so that the balloon 4b side communicates with the outside air, and the air in the balloon 4b is switched from the three-way valve 4d. Let it flow out. When the air pressure disappears, the ceiling opening / closing unit 3 descends by its own weight and closes the vent 8a of the ceiling board 8.

次に、上記のように構成された実施の形態１の動作について説明する。なお、通常時においては、天井開閉ユニット３は天井部２を塞いだ状態となっている。筺体１内の温度は、内部に収容された機器類から発生した熱、外気温、日射による太陽光などにより上昇するが、側壁の通気口１ａから流入した外気が天井板の通気口８ａ、天井開閉ユニット３の内部空間を経て通気口３ｄへ抜けること、及び天井開閉ユニット３の外表面に遮熱塗料が塗布されていることによって筺体１内部の温度上昇が抑えられている。なお、筺体１の内部の温度は温度センサ５によって、制御装置６で計測されている。   Next, the operation of the first embodiment configured as described above will be described. In the normal state, the ceiling opening / closing unit 3 is in a state of closing the ceiling portion 2. The temperature inside the housing 1 rises due to heat generated from the devices housed therein, the outside air temperature, sunlight from sunlight, etc., but the outside air flowing in from the side wall vent 1a is the ceiling plate vent 8a, ceiling By passing through the internal space of the opening / closing unit 3 to the vent 3d and applying a thermal barrier coating to the outer surface of the ceiling opening / closing unit 3, the temperature rise inside the housing 1 is suppressed. The temperature inside the housing 1 is measured by the control device 6 by the temperature sensor 5.

例えば夏季など、外気温が設置地域の平年値よりも大きく上昇し、さらに太陽光の直接照射等による天井部２からの透過熱が大きくなって、筺体１の内部温度が予め設定された所定の温度以上になると、制御装置６に設けられた図示省略しているリレーが働き、３方弁４ｄを、流路が図の上下方向にのみ連通するように切り替えた後、設定された時間コンプレッサ４ａを駆動して圧縮空気を空気パイプ４ｃからバルーン４ｂに送る。バルーン４ｂは空気圧によって膨張し、天井開閉ユニット３が予め設定された所定角度押し上げられる。これにより、天井開閉ユニット３が天井部２から開いた状態になることにより、筺体１の通気口８ａから筺体１内に篭っていた暖められた空気が煙突効果により通気口８ａを通じて活発に外に出て行き、筺体１内の温度を下げることが可能となる。   For example, in the summer season, the outside air temperature rises higher than the normal value in the installation area, and the transmitted heat from the ceiling portion 2 due to direct irradiation of sunlight increases, so that the internal temperature of the housing 1 is set to a predetermined value. When the temperature is higher than the temperature, a relay (not shown) provided in the control device 6 works, and after switching the three-way valve 4d so that the flow path communicates only in the vertical direction in the figure, the set time compressor 4a Is driven to send compressed air from the air pipe 4c to the balloon 4b. The balloon 4b is inflated by air pressure, and the ceiling opening / closing unit 3 is pushed up by a predetermined angle. As a result, when the ceiling opening / closing unit 3 is opened from the ceiling portion 2, the warmed air that has entered the casing 1 from the vent 8 a of the casing 1 is actively released through the vent 8 a due to the chimney effect. It is possible to go out and lower the temperature in the housing 1.

なお、屋外形配電盤を設置するときに、予め設置する地方の緯度や方位あるいは気象データの統計情報などを考慮して天井開閉ユニット３の開放時を含めた傾斜角度を、太陽の反射光の割合が増えるように設定することで、その外表面に塗布されている遮熱塗料による太陽光の反射効果を高め、透過熱量を軽減することができる。また、天井開閉ユニット３が開いたとき、カバー板３ｅが設けられていることにより、大きな異物、鳥などが隙間から侵入するのを防止できる。また、筺体１の内部の温度が所定のレベルを下回ると、温度センサ５が検知して制御装置６は３方弁４ｄの流路を外気に連通するように切り替え、バルーン４ｂ内の空気を外部に流出される。すると、天井開閉ユニット３は自重で下降し、図示省略しているシーリング部材によって天井板８の通気口８ａの外周囲が塞がれる。   In addition, when installing an outdoor type switchboard, the inclination angle including the time when the ceiling opening / closing unit 3 is opened is taken into account in consideration of the local latitude and orientation installed beforehand or statistical information on weather data, etc. By setting so as to increase, the reflection effect of sunlight by the thermal barrier coating applied to the outer surface can be enhanced, and the amount of transmitted heat can be reduced. In addition, when the ceiling opening / closing unit 3 is opened, the cover plate 3e is provided, whereby large foreign objects, birds, and the like can be prevented from entering from the gap. When the temperature inside the housing 1 falls below a predetermined level, the temperature sensor 5 detects that the control device 6 switches the flow path of the three-way valve 4d to communicate with the outside air, and the air inside the balloon 4b To be leaked. Then, the ceiling opening / closing unit 3 is lowered by its own weight, and the outer periphery of the vent hole 8a of the ceiling board 8 is blocked by a sealing member (not shown).

上記のように、実施の形態１によれば、天井開閉ユニット３を開閉可能とし、筺体１の内部の温度が高くなると、温度センサ５がそれを検知して天井開閉ユニット３を開いて、筺体１の内部の熱を筺体の天井部２から直接外へ逃がすように構成したので、配電盤が１日中太陽光に晒されるような厳しい場所に設置された場合でも、日射による熱や収容された機器の発熱による筺体１の内部の温度上昇が抑制される。このため、収納された機器の寿命が延びて耐久性も向上し、信頼性も確保できる。また、駆動装置４として、圧縮空気を利用した駆動手段を用いるようにしたので、天井開閉ユニット３の重量が重い場合でも動作を容易にできる。   As described above, according to the first embodiment, the ceiling opening / closing unit 3 can be opened and closed, and when the temperature inside the casing 1 becomes high, the temperature sensor 5 detects it and opens the ceiling opening / closing unit 3 to open the casing. Since the internal heat of 1 was made to escape directly from the ceiling 2 of the enclosure, even when the switchboard was installed in a harsh place where it was exposed to sunlight all day long, the heat from the solar radiation was contained. The temperature rise inside the housing 1 due to the heat generated by the device is suppressed. For this reason, the lifetime of the accommodated apparatus is extended, durability is improved, and reliability can be ensured. Moreover, since the drive means using compressed air is used as the drive device 4, even when the weight of the ceiling opening / closing unit 3 is heavy, the operation can be facilitated.

また、天井部２を、スリット状の複数の通気口８ａを有する天井板８によって構成したので、筺体１の剛性が保持される。また、例えば中緯度の温帯地域などに設置される場合、年間を通じて天井開閉ユニット３は閉じられている期間の方が長いが、その天井開閉ユニット３が閉じられているときに、天井板８との周囲を図示省略しているシーリング部材で塞ぐようにしたので、周囲からの異物の侵入を防ぐことができる。また、天井開閉ユニット３を傾斜させて、積もった積雪、異物等の除去をも容易に行うことが可能になる。また、無人で管理することが可能となる。   Moreover, since the ceiling part 2 is configured by the ceiling plate 8 having a plurality of slit-shaped vents 8a, the rigidity of the casing 1 is maintained. For example, when installed in a mid-latitude temperate zone, the ceiling opening / closing unit 3 is closed throughout the year, but when the ceiling opening / closing unit 3 is closed, the ceiling plate 8 Since the periphery of is sealed with a sealing member (not shown), it is possible to prevent intrusion of foreign matter from the periphery. In addition, it is possible to easily remove the accumulated snow, foreign matters and the like by inclining the ceiling opening / closing unit 3. Moreover, it becomes possible to manage unattended.

なお、上記実施の形態では、駆動装置４として、コンプレッサ４ａとバルーン４ｂを用いたものについて説明したが、勿論これに限定されるものではなく、例えば電動モータやアクチュエータなどを用いたものでも差し支えない。また、温度センサ５を天井開閉ユニット３の下部に配設したが、天井板８の下部などに設けても差し支えない。また、天井開閉ユニット３が開いたときの状態を保持するためにラッチ機構を付加し、その状態を解除するために引外し装置を付加するようにしても良い。   In the above embodiment, the drive device 4 using the compressor 4a and the balloon 4b has been described. However, the drive device 4 is of course not limited to this, and may be one using an electric motor or an actuator, for example. . Further, although the temperature sensor 5 is disposed in the lower part of the ceiling opening / closing unit 3, it may be provided in the lower part of the ceiling board 8 or the like. Further, a latch mechanism may be added to hold the state when the ceiling opening / closing unit 3 is opened, and a tripping device may be added to release the state.

また、前板３ａを下方向に伸ばしてカバー板３ｅを省略しても良い。さらに、筺体１の屋根部分全体を開閉するようにしたが、天井開閉ユニット３を屋根の一部を開閉するように構成し、天井開閉ユニット３を開くときの角度を外気温との温度差に応じて可変に構成し、天井開閉ユニット３の傾斜を逆に構成し、あるいはヒンジ７の設置位置を逆にして筺体１の後部側を開くように構成するなど、この発明の範囲内で種々の変形や変更が可能であることは言うまでもない。   Further, the cover plate 3e may be omitted by extending the front plate 3a downward. Further, the entire roof portion of the housing 1 is opened and closed, but the ceiling opening and closing unit 3 is configured to open and close a part of the roof, and the angle when opening the ceiling opening and closing unit 3 is set to a temperature difference from the outside air temperature. Depending on the configuration, the ceiling opening / closing unit 3 may be configured with the inclination reversed, or the rear side of the housing 1 may be opened with the installation position of the hinge 7 reversed. Needless to say, modifications and changes are possible.
