遮蔽電極には通常紙製の巻装体が付けてある。As is apparent from the accompanying drawings, shield electrodes 3 and 4 having a tubular cross section are arranged at both ends of a frame 1 of kraft paper used as a support for the contact 2 of the tap changer under load. In this case, the shield electrodes 3 and 4 are in contact with the tubular insulating members 5 and 6, respectively, and the end faces 7 and 8 are aligned with the cross section of the shield electrodes 3 and 4. Further, the insulating members 5 and 6 together with the protrusions 9 and 10 are the frame 1 of the kraft paper.
Fit in the hole. A tightening belt 11 made of an insulating material is provided around the shield electrode, and the tightening belt 11 is an insulating member 5,
It is introduced by crossing inside 6. Since the tightening belt 11 is tightened by the tightening clamp 12 arranged in the shaded portion of the electric field, both the shield electrodes 3 and 4 can be mechanically and securely fixed to the frame 1 of the kraft paper. These shield electrodes
Electrical connection of the contacts 3 and 4 to the contact 2 is effected by a simple coil spring 13 and 14, respectively. These coil springs are, for example, hard soldered to both the shield electrode 3 or 4 and the contact 2. This connection is naturally made in the shadow of the electric field as well. Obviously, both the shield electrodes 3 and 4 and the coil spring connecting parts 13 and 14 can be provided with auxiliary insulating members. Therefore, the contraction tube or the glass fiber hoses 15 and 16 can be used for the coil spring connection portion.
Therefore, the coil spring connecting portions 14 and 15 are further stabilized.
The shield electrode is usually provided with a paper winding body.
