済となる欠点があった。Conventionally, stationary induction electric devices such as transformers and accelerators have mainly been oil-filled type devices that are insulated and cooled with insulating oil. However, in the case of such oil-filled electrical equipment, in the unlikely event that an accident occurs, 1. If this occurs, there is a risk that the insulating oil may ignite, an explosion due to the ignition, or a fire may occur. Particularly in recent years, such disaster prevention measures have become an important issue for transformers installed in ground substations of buildings and in urban areas due to restrictions on installation locations. From the point mentioned above, recently the conventional oil-filled method has been replaced with sulfur hexafluoride (
Gas-insulated stationary induction electrical equipment that performs insulation and cooling using an insulating gas such as SFa) gas has been developed and is being put into practical use. Since such an insulating gas is inert, there is no risk of explosion or fire, and it is a very preferable insulating medium for disaster prevention. But don't expect that. However, in recent years, electric devices have become increasingly taller and larger in capacity, and the windings generate a large amount of heat, making it difficult to cool them uniformly and effectively. In other words, as the capacity increases and the voltage increases, it is necessary to thicken the insulation coating of the winding conductor, but since the insulating gas used as the cooling medium is a gas, heat transfer is poor, so it is necessary to force the cooling medium near the winding. Even with circulation, the windings are not sufficiently cooled. Therefore, it is necessary to take measures such as increasing the thickness of the winding conductor to reduce the current density, resulting in a large size and an uneconomical disadvantage.

ある。[Summary of the Invention] In order to achieve the above object, the present invention uses a winding housed in a tank together with an insulating gas as a hollow conductor, and forcibly fills an insulating cooling medium such as an insulating gas inside the hollow conductor. The windings are circulated to cool them, thereby improving the cooling effect and reducing the size of the windings.

In FIG. 1, reference numeral 1 denotes a transformer tank, which houses the contents of the transformer consisting of an iron core 2 and a winding 4 wound around the iron core 2 via an insulating tube 3. This tank 1 is filled with an insulating gas 5 such as sulfur hexafluoride (SFa). Reference numeral 6 represents a cooler provided in a cooling medium circulation path, which will be described later, and 7 represents a pump.

The winding is constructed by applying A pipe 11a communicating with the hollow portion 10 of the winding 4 is provided near the upper end of the winding 4, and a pipe 11b is similarly provided near the lower end of the winding 4.
t711a and llb are piping 12 made of insulating material, respectively.
A cooler 6 outside the tank 1 as shown in FIG.
It may be connected to the pump 7 to form a circulation path for a cooling medium, and may be passed through this pipe 12 into the hollow portion 10 of the winding 4, or may be an insulating gas for cooling other seeds.

な循環が可能となる。With such a configuration, the winding 4 is connected to the pump 7.
By forcibly circulating the cooling medium in the hollow part 10 as shown by the arrow in the figure, the generated heat is transferred to the winding 4.
It is absorbed by the cooling medium that can cross in direct contact with the cooling medium and flows to the external cooler 6. The cooling medium heated by the cooler 6 is cooled and flows into the hollow part 10 of the winding 4 again, and the winding is cooled by this turning. In particular, if an insulating liquid is used as the cooling medium, the cooling effect will be even greater. In addition, the pump 7 requires high pressure in order to circulate the cooling medium into the hollow part 10 of the forced C winding 4.
Smooth circulation can be achieved by appropriately adjusting the size and number of b, or by appropriately dividing or changing the length through which the cooling medium passes through the winding 4.
