Description

本実施形態は、受配電技術分野に使用される変圧器に関する。 The present embodiment relates to a transformer used in the power receiving and distribution technical field.

従来の変圧器として、タンクの側面にラジエータを設置し、タンク内の絶縁油がラジエータの間に循環するように構成され、これにより絶縁油が冷却されると共にタンク内に収納されている、変圧器本体の発熱を抑制するようにしたものがある。 As a conventional transformer, a radiator is installed on the side of the tank so that the insulating oil in the tank circulates between the radiators, whereby the insulating oil is cooled and stored in the tank. There is one that suppresses the heat generation of the main body.

前述した従来の変圧器にあっては、周辺機器の配置、配線接続の関係から設置箇所が限られていたため、冷却性能を向上させるにも限界があった。 In the conventional transformer described above, the installation location is limited due to the arrangement of peripheral devices and the connection of wiring, so there is a limit to improving the cooling performance.

本実施形態は、冷却性能の向上と効率化が図れる変圧器を提供することを目的とする。 An object of the present embodiment is to provide a transformer capable of improving the cooling performance and increasing the efficiency.

本実施形態は、前記目的を達成するため、タンク内に絶縁媒体と共に収納され、鉄心とこの鉄心に巻回された巻線からなる変圧器本体と、前記タンクの側面に配設され、前記タンク内の絶縁媒体が循環可能に構成されたラジエータと、前記タンクの上部に空間を形成するように配設され、太陽光等の輻射熱を吸収する輻射体と、前記輻射体に一端側が連結され、かつ他端側が前記ラジエータの底部に連結され、前記輻射体で吸収した輻射熱を前記ラジエータに伝達するヒートパイプとを具備した変圧器である。 In order to achieve the above object, the present embodiment is accommodated in a tank together with an insulating medium, and includes a transformer main body comprising an iron core and a winding wound around the iron core, and disposed on a side surface of the tank. A radiator configured to be able to circulate the insulating medium therein, disposed so as to form a space above the tank, a radiator that absorbs radiant heat such as sunlight, and one end side connected to the radiator; And the other end side is connected with the bottom part of the said radiator, It is a transformer provided with the heat pipe which transmits the radiant heat absorbed with the said radiator to the said radiator.

以下、本実施形態の変圧器を図１、図２を参照して説明する。タンク１１内に絶縁媒体例えば絶縁油（図示せず）と共に収納され、鉄心（図示せず）とこの鉄心に巻回された巻線（図示せず）からなる変圧器本体１と、タンク１１の側面に配設され、タンク１１内の絶縁油が循環可能に構成されたラジエータ２と、タンク１１の上部に空間を形成するように配設され、太陽光等の輻射熱を吸収する輻射体４と、輻射体４に一端側が連結され、かつ他端側がラジエータ２の底部に連結され、輻射体４で吸収した輻射熱をラジエータ２に伝達するヒートパイプ５とを具備している。 Hereinafter, the transformer of this embodiment is demonstrated with reference to FIG. 1, FIG. The tank 11 is housed together with an insulating medium such as insulating oil (not shown), and includes a transformer body 1 including an iron core (not shown) and a winding (not shown) wound around the iron core, A radiator 2 disposed on the side surface and configured to allow the insulating oil in the tank 11 to circulate; a radiator 4 disposed to form a space above the tank 11 and absorbing radiant heat such as sunlight; The radiator 4 includes a heat pipe 5 having one end connected to the radiator 4 and the other end connected to the bottom of the radiator 2 and transmitting the radiant heat absorbed by the radiator 4 to the radiator 2.

以上述べた実施形態によれば、太陽光等の輻射熱６はタンク１１の上部に設けた輻射体４で吸収されるので、変圧器本体１の温度上昇が抑えられ、タンク１１の上部から輻射熱を効率的にヒートパイプ５に集めることができる。この吸収された熱７はヒートパイプ3を通してラジエータ2の下部に送られる。ラジエータ2の下部に送られた熱８により、ラジエータ2の周囲で自然対流９が発生するので、ファン等の送風装置を用いずに変圧器本体１が冷却される。この結果、冷却性能の向上と効率化が図れる。 According to the embodiment described above, since the radiant heat 6 such as sunlight is absorbed by the radiant body 4 provided on the upper portion of the tank 11, the temperature rise of the transformer body 1 is suppressed, and the radiant heat is generated from the upper portion of the tank 11. It can be efficiently collected in the heat pipe 5. The absorbed heat 7 is sent to the lower part of the radiator 2 through the heat pipe 3. The natural convection 9 is generated around the radiator 2 by the heat 8 sent to the lower part of the radiator 2, so that the transformer main body 1 is cooled without using a blower such as a fan. As a result, the cooling performance can be improved and the efficiency can be improved.

また、リフタを使用して変圧器含む遮断装置全体を引き出す時、リフタの位置決めが簡易にできる。 Also, when the lifter is used to pull out the entire circuit breaker including the transformer, the lifter can be easily positioned.
