く時間がかかる。According to the conventional technique described above, there are the following inconveniences. First, since the temperature of the insulating oil is not controlled, the amount of insulating oil is different each time, and when the insulating oil degassed in the oil tank 1 is guided to the oil amount adjusting tank 3 via the lift pump 4. Bubbles are generated in the insulating oil flowing between the lift pump 4 and the oil amount adjusting tank 3. Further, when the insulating oil in the oil tank 1 is deaerated, the volume of the oil tank 1 is large compared to the amount of the insulating oil and the deaeration time is inefficient and takes a long time.

脹量を吸収する位置まで治具により、収縮させておく。In order to inject the insulating oil with the above-mentioned device, first, a prescribed amount of insulating oil suitable for the pipe type to be injected into the oil tank 1 is introduced from the oil line, and the heater 1 is introduced.
It is controlled to a constant temperature of 0, for example, about 50 ° C. Next, the vacuum pump 2 connected to the oil tank 1 by piping performs deaeration of 1.3 Pa (1 × 10 −2 Torr) for removing the air in the insulating oil filled in the oil tank 1. At this time, the inside of the X-ray tube container 9 is also degassed while the temperature of the container 13 is maintained at about 50 ° C. In this case, the operation of another vacuum pump 6 connected to the residual oil tank 5 through the connection fitting 8 causes 1.3 Pa (1 × 10 -2 Torr).
Degas. At this time, the temperature of the X-ray tube container 9 is made substantially equal to the temperature of the insulating oil. Then, the empty tray 14 that absorbs the expanded amount of oil is contracted by a jig to a position where the expanded amount is absorbed at an oil temperature of about 50 ° C. during actual operation.

する。In the above case, when the temperature of the X-ray tube container 9 and the temperature of the insulating oil are almost equal, an intermediate temperature of the temperature change (for example, 20 to 80 ° C.) during the operation of the X-ray tube apparatus is added. A predetermined temperature (for example, 40 to 60 ° C.) (for example, 5
At 0 ° C.), both are heated with a heater and controlled to the same or almost the same temperature (difference within ± 3 ° C., preferably within ± 2 ° C.).

注入が完了となる。Next, a sufficiently deaerated insulating oil is injected into the X-ray tube container 9 which is also sufficiently deaerated in a specified amount. The inside of the X-ray tube container 9 is evacuated by the vacuum pump 6 even during the injection of the insulating oil. When all the insulating oil has been injected, the vacuum pump 2 and the vacuum pump 6 are stopped, the atmosphere is immediately released, and the extra insulating oil accumulated in the connection fitting 8 is operated to operate the vacuum pump 6. The X-ray tube container 9 is discharged to a prescribed position, and a series of injection of insulating oil is completed.

である。As described above, the method of injecting the insulating oil according to the present invention determines the injection amount for each tube type by repeating the several cycles of the conventional deaeration-injection of a small amount of insulating oil. By controlling the temperature of the X-ray tube container 9 and the insulating oil, it has become possible to more stably inject and fill the insulating oil than before. And since there is no temperature difference, it is possible to supply a fixed amount of insulating oil according to the pipe type. or,
Since the oil tank 1 also has a large diameter and a low height, the deaeration time can be shortened, and the filling time of the insulating oil can be reduced to about 2/3 as compared with the conventional case. It is also an important factor that this was achieved with the minimum number of components by reviewing the components.
