(2) The entire specification shall be amended as shown in the attached sheet. Amended Description 1 Title of the Invention Shield Cover Attachment Method 2, Claims A support fixture fixed to an electrical device and a shield cover integrally configured in advance, the shield cover being attached to the support fixture from above the support fixture. Covering the electrical equipment and fixing it to the electrical equipment using the supporting metal fittings, lifting the electrical equipment together with the shield cover to a predetermined position using eye bolts that penetrate the shield cover and attaching to the supporting metal fittings, and then removing the eye bolts. A method for removing a shield cover, characterized in that the surface of the shield cover is made smooth so that there is no possibility of disturbance of the electric field. 3. Detailed Description of the Invention The present invention relates to a method for attaching a shield cover for corona prevention in high-voltage electrical equipment. When attaching a shield cover to the head of a high-voltage electrical device for testing, conventionally, as shown in Figure 1, after the electrical device has been assembled, a shield cover is attached to the support fitting 2 provided on the side of the head of the electrical device l, as shown in Figure 1.
The divided shield covers 3''A, 3B, and 3C were assembled together in the direction of each arrow shown in the figure, and screwed together in several cases.In this case, the shield cover was attached to the head of the equipment at 1, For example, for Act, 500kV, it must be installed at a height of 10m or more above the ground.In order to install several divided shield covers with a diameter of 2m or more at such a high place, it is necessary to set up a scaffold. I will do it, but
This is an extremely difficult task. In addition, when the shield cover is assembled, it is approximately spherical, but when it is divided, it bends and deforms.
At the time of J, there is a need to be careful to hold the device so that it will not be deformed by a large number of workers, and working at heights is particularly difficult. Furthermore, when assembling the divided shield covers, it is necessary to assemble the joints smoothly due to the nature of corona prevention, but since the shield covers are aluminum acid, they may deform due to vibrations during transportation. This also makes installation difficult. The present invention solves these drawbacks by integrating the seal and cover in advance so that they can be easily installed. The details will be explained below. FIG. 2 shows an embodiment of the present invention, in which the electrical equipment l is equipped with several supporting metal fittings 4 on the top of the electrical equipment l using the supporting parts 4a, and then the integral shield cover 5 is lifted up and the opening 5a is inserted into the electrical equipment l. It is placed over the electrical equipment 1 from above as shown by the arrow, and fixed to the mounting base 4b of the support fitting 4 using suitable means such as screws 9°lO as shown in FIG. Although the description is omitted in Fig. 2 for simplicity, there is a third
As shown in the figure, a tapped hole 6 for an eye bolt that can lift the entire electrical device is provided in advance, and a corresponding through hole 7 is also provided in the integrally formed shield cover 5. In this case, since the shield force/he-5 is already integrated, the work of fixing it to the electrical equipment is much easier than before, and it can be lifted together with the electrical equipment l using the eye bolt 8. There is no risk of any deformation occurring. In this way, after installing the shield cover on the 4L<Old City electrical equipment, the whole thing can be lifted up and placed at +9i position 16. That is, as shown in FIG. 2 on the ground, this support metal fitting 4 is first attached to the top of the electrical equipment l, then the shield cover 5 is placed over it, and the support metal fitting 4 is attached to the base 4b.
Fixed to. After completing several shield covers,
As shown in Fig. 3, several eye holes 8 for lifting are inserted through the through hole 7 of the shield cover into the eye holes 6, and the entire electrical equipment l is hung together with the shield cover 5 by the eye holes 8. It can be transported and placed at the location. After the electrical equipment 1 is installed in the predetermined position, the eye bolts 8 are removed, several bolts (not shown) with suitable shapes for heads are placed in the bolt holes 6, and the surface of the shield cover 5 is exposed to the electric field. Make it smooth so that there is no risk of disturbing it. In this way, working at height is carried out very simply. In the above explanation, the supporting metal J44 is shown in FIGS.
As shown in the figure, a support part 4 for fixing to electrical equipment
a and a mounting base 4b for fixing the shield cover without fear of distortion or deformation are integrated, but in the present invention, 4a and 4b are separated and carried out as follows. You can also do that. The support metal fittings 4 shown in FIG. 2 are divided in advance into a block 4a and a bracket 4b, and the support parts 4a are attached to the electrical equipment l. On the other hand, a mounting base 4b is fixed in advance to a predetermined location on the inner surface of the integrally assembled shield cover 5, and the entire shield cover is appropriately held and lifted up to cover the electrical equipment l from above. For example, a fixing arm (not shown) is provided on the support part 4a in advance to protrude to the side, and the mounting base 4b is attached to the support part by an appropriate means such as a bolt through the shield cover 5 from the outside. Fix it to the fixing arm 4a. In this way, the shield cover 5 already has several lines 4 inside.
Since the shield cover 5 is fixed to the support part 4a via the mounting base 4b in a fixed state, the shield cover 5 can be easily attached to the electrical equipment several times without fear of deformation or the like. In this way, several shield covers can be placed on the electrical equipment before installation on the ground, and the entire electrical equipment and shield cover can be lifted up by the eye port 8 shown in FIG. 3, transported to a predetermined position, and installed. As explained above, the present invention eliminates the need for attaching a shield cover to an electrical device by assembling a shield cover divided into multiple pieces by working at high places as in the past, and it is possible to install a shield cover as an integrated shield. It is only necessary to write a few verses of the cover, and it can bring about great effects such as saving labor and shortening the time required. 4.
