Abstract

PURPOSE:To improve the cooling efficiency of windings by a method wherein the insulating spacer, which supports the winding to be arranged on the oil discharging side, is formed with an electric insulating material having high thermal conductivity and the end part of the spacer is protruded from the winding part. CONSTITUTION:The spacers 3 and 3', which support a winding 4, are fixed on the insulating wall 2 formed by a plate type insulating material, and the gap of the insulating spacer located adjoining to said wall performs an additional function as an oil-flowing duct. Also, the insulating spacer 3', to be provided on the oil discharging side, is formed using an electric insulating material having high thermal conductivity such as a special ceramic, and its end part is protruded at the part, located outside the winding 4, where oil flows excellently, and used as a heat dissipating end. With the constitution above-mentioned, the cooling efficiency at the part where temperature goes up most at the winding 4 of the conventional device can be increased, thereby enabling to lower the temperature of the winding.

有していた。In the above configuration, as the insulating oil moves from the oil supply side A to the oil drain side B as shown by the arrow, its temperature rises due to the heat generated by the winding 4, and the temperature of the insulating oil rises due to the heat generated by the winding 4. The problem is that the oil flow stagnates at the bottom of the wire 4 and the winding temperature increases.

This is the point that I made.

絶縁油の油流ダクトをも兼ねている。Next, FIG. 2 shows the structure of an embodiment of an oil-fed type outer iron pressurizer according to the present invention. In the figure, insulating spacers 3 and 3' supporting the winding 4 are fixed to an insulating wall 2 formed of a plate-shaped insulator, and the gap between the insulating spacers in contact also serves as an oil flow duct for cooling insulating oil. There is.

The good part should be protruded and used as a heat dissipation end.
