| Zusammenfassung: | The utility model relates to a steam shielding device used in a medium-voltage switch cabinet for a vacuum switching tube, and aims to acquire a shielding device which has a high heat energy absorption rate as well as good protection against metal deposition caused by high-energy light arc impact on the inner ceramic surface. The shielding device provided by the utility model is composed of at least two concentrically arranged cylindrical shielding pieces, a space or a hollow space is reserved between the so arranged inner shielding piece and the at least one outer shielding piece, and the inner shielding piece is provided with openings which correspond to the hollow spaces between the shielding pieces. |
