い欠点があった。By doing this, the equipotential lines 9 are distributed along the curvature of the open end of the cover 10 and the core fastener 4, as shown by dotted lines in the figure. , the equipotential lines 9 are less dense than in the case of FIG. The cover 10 must be removed when increasing the iron knob supply bolt 11 (see Figure 2) and the lock nut 12 for the winding tightening fixture, which are used to attach the fitting 6 and the core supply fitting 4. There were drawbacks.
本発明は以上の点に鑑みなされたものであり、その目的
とするところは、巻線締付金具の電界緩和を容易にした
変圧器を提供するにある。The present invention has been made in view of the above points, and an object of the present invention is to provide a transformer that facilitates the relaxation of the electric field of the winding fastening fitting.
すなわち本発明は、巻線締付金具に電界緩和用のシール
ドを着脱自在に取υ付けたことを特徴とするものである
。That is, the present invention is characterized in that a shield for mitigating an electric field is detachably attached to the winding fastening fitting.

ることにより巻線締付金具６の電界緩和が容易となって
、巻線締付金具６の電界緩和を容易にした変圧器を得る
ことができる。[Embodiments of the Invention] Hereinafter, the invention will be explained based on the illustrated embodiments. An embodiment of the present invention is shown in FIGS. 4 and 5. Note that parts that are the same as those in the conventional model are given the same reference numerals, and therefore their explanations will be omitted. In this embodiment, a shield 13 for mitigating the electric field is detachably attached to the winding clamp 6. Like this-”
As a result, the electric field of the winding fastener 6 can be easily relaxed, and a transformer can be obtained in which the electric field of the winding fastener 6 can be easily relaxed.
すなわち端部に曲率をもたせた電界緩和用のシールド１
３自身にめねじを形成して巻線締付金具６に螺合した。In other words, the shield 1 for mitigating the electric field has a curvature at the end.
3 was formed with a female thread and screwed onto the winding fastening fitting 6.
このようにすることによりシールド１３を巻線締付金具
６に螺合するだけで等電位線９ｉ７Ｊ：図中に点線で示
