った。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a transformer, and relates to a transformer used in equipment that is fully equipped with heat generation countermeasures and electromagnetic wave countermeasures. Countermeasures against electromagnetic noise were taken, such as wrapping copper tape around the device, but nothing was done to prevent the heat trapped in the copper tape.
上述した従来のトランスは、銅テープが巻かｎているた
め、鉄損や銅損等にエフ発生した熱量が。Since the conventional transformer described above is wrapped with copper tape, the amount of heat generated is due to iron loss, copper loss, etc.
トランス内部にこもってしまい１巻線のエナメルや、絶
縁テープが熱にＬり溶け、短絡事故の可能性を有すると
いう欠点があった。There was a drawback that the enamel of the first winding and the insulating tape were trapped inside the transformer and melted due to the heat, leading to the possibility of a short circuit accident.
本発明のトランスは、巻線の周囲？囲む工うな放熱板と
、前記放熱板全電気的に接続し、かつ巻線の周囲全金属
で電気的に完全に囲んでしまうような押え金具全有する
。Is the transformer of the present invention around the winding? It has a heat sink that surrounds the heat sink, and a holding metal fitting that electrically connects the heat sink and completely surrounds the winding with metal.
次に本発明について、図面全参照して説明する。 Next, the present invention will be explained with reference to all the drawings.

巻線の上部全層い、押え金具２は。FIG. 1 is an external view of an embodiment of the present invention, and FIG. 2 is a sectional view of the transformer of the present invention. The heat dissipation plate 1 covers the entire upper layer of the transformer winding, and the holding metal fitting 2 covers the entire upper layer of the transformer winding.
巻線の下部を履い放熱板１の端と他端を接続し。Connect the bottom of the winding and the other end of heat sink 1.
電気的には、あたかも巻線の周囲音１本の金属ベルトで
巻いているのと同等になっている。また。Electrically, the ambient sound around the winding is equivalent to winding it with a single metal belt. Also.
巻線上部と、放熱板１の間には、シリコンゴムが充てん

効果がある０As explained above, the present invention can completely shield electromagnetic noise caused by leakage, magnetic flux, etc. by using a transformer-wound all-metal belt, and a part of the metal belt can also act as a heat sink. As a result, the heat generated inside the transformer can be dissipated, which has the effect of greatly reducing the possibility of short circuit accidents due to heat.
