Description

本発明は、変圧器を収納した盤本体に吸気ファンと排気ファンを設け、前記吸気ファンにより前記盤本体内に吸入した外気で前記変圧器を冷却したのち前記排気ファンにより前記盤本体外に放出する風冷式変圧器に関するものである。   In the present invention, an air intake fan and an exhaust fan are provided in a panel body housing a transformer, and the transformer is cooled by outside air sucked into the panel body by the intake fan, and then discharged to the outside of the panel body by the exhaust fan. It relates to a wind-cooled transformer.

風冷式変圧器として、図４に示すように、変圧器１０２を収納した盤本体１０３の前面に吸気ファン（以下、前面ファン）１０４を設けるとともに、天井に排気ファン１０５を設け、前面ファン１０４により盤本体１０３内に吸入した外気で変圧器１０２を冷却した後に外気を排気ファン１０５により盤本体１０３外に放出する風冷式変圧器１０１が知られている。１０６は、前面ファン１０４により盤本体１０３内に吸入した外気を効果的に変圧器２に当てるための風ガイドである。   As an air-cooled transformer, as shown in FIG. 4, an intake fan (hereinafter referred to as a front fan) 104 is provided on the front surface of a panel body 103 in which the transformer 102 is housed, and an exhaust fan 105 is provided on the ceiling. There is known an air-cooled transformer 101 that cools the transformer 102 with the outside air sucked into the panel main body 103 and then discharges the outside air to the outside of the panel main body 103 by the exhaust fan 105. Reference numeral 106 denotes a wind guide for effectively applying outside air sucked into the panel main body 103 by the front fan 104 to the transformer 2.

上記風冷式変圧器１０１は、変圧器１０２の前面側を効果的に冷却することができるが変圧器１０２の背面側を効果的に冷却することが困難である。   The air-cooled transformer 101 can effectively cool the front side of the transformer 102, but it is difficult to effectively cool the back side of the transformer 102.

そこで、図５（Ａ），（Ｂ）に示すように、盤本体１０３の背面にも吸気ファン（以下、背面ファン）１０７を設け、変圧器１０２の前面及び背面の両面から変圧器１０２を効果的に冷却できるようにした風冷式変圧器も開発されている。（盤本体の前面と背面に吸気ファンを設けたものとして、例えば、特許文献１）。   Therefore, as shown in FIGS. 5A and 5B, an intake fan (hereinafter referred to as a rear fan) 107 is also provided on the back of the panel main body 103, and the transformer 102 is effective from both the front and back surfaces of the transformer 102. Air-cooled transformers have also been developed that can be cooled naturally. (For example, Patent Document 1 assumes that intake fans are provided on the front and back of the panel body.)

また、風冷式変圧器として、図６に示すように、変圧器１０２の床１０８の下部に冷却ファン１０９を取付け、吸気口１１０から吸入した冷却風を床上に吹き上げ、吹き上げた冷却風をダクト１１１で変圧器１０２に当てて冷却する風冷式変圧器も開発されている。（例えば、特許文献２）。   As an air-cooled transformer, as shown in FIG. 6, a cooling fan 109 is attached to the lower part of the floor 108 of the transformer 102, the cooling air sucked from the air inlet 110 is blown onto the floor, and the blown cooling air is ducted. An air-cooled transformer that cools against the transformer 102 at 111 has also been developed. (For example, patent document 2).

ところで、図５に示した、盤本体１０３の前面に前面ファン１０４を設け、背面に背面ファン１０６を設け、天井に排気ファン１０５を設けた風冷式変圧器には次に述べるような問題点があった。
（１）前面ファン１０４や排気ファン１０５は、フロント側からのメンテナンス（以下、フロントメンテナンス）を行うことが容易であるが、背面ファン１０６は、フロントメンテナンスを行うことが容易でない。
（２）変圧器１０２を盤本体１０３から引き出して、背面ファン１０６をフロントメンテナンスすることも可能であるが、変圧器１０２は重量が重いために、変圧器１０２を引き出す作業は容易でない。
（３）変圧器１０２を盤本体１０３から引き出さずに、背面ファン１０６のフロントメンテナンスを行なうために、図５に示す変圧器１０２と盤本体１０３の間の隙間Ｇを大きくとり、この隙間Ｇから作業員が変圧器１０２の背面側に回りこんで、背面ファン１０６のメンテナンスを行なうことも考えられるが、そのためには盤本体１０３の横幅Ｗを大きくしなければならず、風冷式変圧器を小型化する上での障害になる。 Incidentally, the air-cooled transformer shown in FIG. 5 in which the front fan 104 is provided on the front surface of the panel body 103, the rear fan 106 is provided on the rear surface, and the exhaust fan 105 is provided on the ceiling, has the following problems. was there.

It is conceivable for an operator to go around to the rear side of the transformer 102 and perform maintenance of the rear fan 106. To that end, the width W of the panel body 103 must be increased, and a wind-cooled transformer is installed. This is an obstacle to downsizing.

また、図６に示した、変圧器１０２の床下部１０８に冷却ファン１０９を取付けて床下から冷却風を吹き上げて変圧器１０２を冷却する方式の風冷式変圧器は、冷却ファン１０９が変圧器１０２の床１０８の下部の狭い空間に配置されているために冷却ファン１０９のメンテナンスや取り付けや取外しが面倒であるという問題点があった。   In addition, the cooling fan 109 in which the cooling fan 109 is attached to the lower floor 108 of the transformer 102 and the cooling air is blown from the lower floor to cool the transformer 102 shown in FIG. Since the cooling fan 109 is disposed in a narrow space below the floor 108 of 102, there is a problem that maintenance, attachment, and removal of the cooling fan 109 are troublesome.

次に、風冷式変圧器１の作用について説明する。前面ファン４ａ，４ｂ，４ｃおよび底面ファン５を作動させると外気が盤本体３内に吸入され、吸入された外気は、前面ダクトおよび背面ダクト６により変圧器２の前面側と背面側に導かれて、変圧器２の前面側および背面側から効果的に冷却した後に、前記排気ファン７により盤本体３の外部に放出される。   Next, the operation of the air-cooled transformer 1 will be described. When the front fans 4a, 4b, 4c and the bottom fan 5 are operated, the outside air is sucked into the panel body 3, and the sucked outside air is guided to the front side and the back side of the transformer 2 by the front duct and the rear duct 6. Then, after effectively cooling from the front side and the back side of the transformer 2, it is discharged to the outside of the panel body 3 by the exhaust fan 7.

そして、前面ファン４ａ，４ｂ，４ｃの修理やメンテナンスが必要になった場合には、据付プレート固定ネジ１９によるネジ止めを外して、前面ファン４ａ，４ｂ，４ｃを手前側に引くと、前記ボス１８がボス挿入穴１４ｃから抜け出て、前面ファン４ａ，４ｂ，４ｃは、第１フレーム１４から取り外されて、前面ファン４ａ，４ｂ，４ｃの修理やメンテナンスを容易に行うことが可能になる。なお、前面ファン４ａ，４ｃは、第１フレーム固定ネジ１６によって据付プレート１７が第１フレーム１４とともに台座９に共締めされているので、前面ファン４ａ，４ｃを取り外す場合には、前記第１フレーム固定ネジ１６によるネジ止めを外さなければならないのは勿論のことである。   When the front fan 4a, 4b, 4c needs to be repaired or maintained, the screw with the installation plate fixing screw 19 is removed, and the front fan 4a, 4b, 4c is pulled to the front side. 18 comes out of the boss insertion hole 14c, and the front fans 4a, 4b, 4c are removed from the first frame 14, and the front fans 4a, 4b, 4c can be easily repaired and maintained. The front fans 4a and 4c have the mounting plate 17 fastened together with the first frame 14 together with the base 9 by the first frame fixing screws 16. Therefore, when removing the front fans 4a and 4c, the first frame Needless to say, the fixing screw 16 must be removed.

また、底面ファン５の修理や取換え等が必要になった場合には、前面ファン４ａ，４ｂ，４ｃを取り付けた侭の状態で、前記４本の第１フレーム固定ネジ１６を外して台座９から第１フレーム１４を取り外して盤本体３の前面側に引き出す。   When the bottom fan 5 needs to be repaired or replaced, the four first frame fixing screws 16 are removed while the front fans 4a, 4b, 4c are attached, and the base 9 is removed. The first frame 14 is removed from the main body 3 and pulled out to the front side of the panel body 3.

第１フレーム１４を引き出すと、そのあとに底面ファン５を取り外すのに必要な空スペースが発生する。そこで、据付プレート固定ネジ２３によるネジ止めを外して底面ファン５を手前側に引くと、前面ファン５の背面側に設けたボス２２がボス挿入穴１５ｃから抜け出で、底面ファン５は、第２フレーム１５から取り外された状態になる。そこで、前記空スペースを利用して、底面ファン５を盤本体３の外部に引き出して、底面ファン５の修理や取換え等を容易に行うことができる。   When the first frame 14 is pulled out, an empty space necessary for removing the bottom fan 5 is generated thereafter. Therefore, when the bottom plate fan 5 is pulled forward by removing the screw fixing by the installation plate fixing screw 23, the boss 22 provided on the back side of the front fan 5 comes out of the boss insertion hole 15c, and the bottom fan 5 The state is removed from the frame 15. Therefore, by using the empty space, the bottom fan 5 can be pulled out to the outside of the panel body 3, and the bottom fan 5 can be easily repaired or replaced.
