In order to solve this problem, the present invention first insulates the support plate from the transformer core clamping metal via the first support insulator, whereas in the previous application the secondary coil was simply attached and held on the high voltage deck. Then, the secondary coil is insulated and attached to this support plate via a second support insulator. In this way, the secondary coil can be attached and held without fear of damage during transportation.

Figure 1a is a front view showing an embodiment of the present invention, Figure 1b is a front view showing an embodiment of the present invention.
is a sectional view taken along cutting line B-B, and c is a side view. Here, the insulator mounting bracket 1 is attached to the iron core tightening bracket 15.
A potential fixing plate 1 outside the secondary coil 5 is fixed on the lower surface of the first supporting insulator 17 via a second supporting insulator 19, and a supporting plate 18 is attached thereon.
3 is fixed and the secondary coil is held in a predetermined coaxial position with respect to the primary coil. Note that shields 20 for alleviating electric fields are inserted into the upper and lower mounting portions of the first and second support insulators 17 and 19, respectively.

る。 Here, as described above, the support plate 18 is made of a metal plate such as an iron plate having sufficient strength, and is configured to hold the secondary coil 5a without any trouble.
Note that the support plate should not be left in an insulated state in order to alleviate the electric field, but should be connected with a protective resistor 8 using lead wires as appropriate.
Connect to the input end of Furthermore, although FIG. 1 shows the case where only the uppermost secondary coil 5a is gas-insulated, when the next-stage secondary coil 5b is also gas-insulated, a supporting insulator is attached to the upper secondary coil 5a. The secondary coil 5b can be held through the secondary coil 5b.

(A) The transformer is housed in a sealed container filled with insulating gas. .

すなわち、この(C)、(D)の記載が先願と本考案と

自の効果を得ることができる。 That is, the descriptions in (C) and (D) are the differences between the prior application and the present invention, and the configuration of (D) allows the unique effects of the present invention to be obtained.

In this way, both ends of the support plate 18 are fixed to strong iron core clamping fittings, and since the support plate itself is made of a metal plate with sufficiently high mechanical strength, such as an iron plate, deflection due to the weight of the secondary coil 5a is ignored. Therefore, there is no risk of problems occurring due to impacts during transportation, and the drawbacks of conventional high-pressure decks made of insulating plates can be overcome. Further, since the support plate 18 is a conductor and the potential is maintained at the highest DC potential, there is a substantially equal electric field between it and the upper secondary coil 5a, and good creeping insulation can be obtained by the support insulator.
