Abstract
The invention discloses a triangular shielding layer of a three-phase superconducting cable. The triangular shielding layer comprises three single-phase superconducting cables and is characterized by further comprising metal soft wires, wherein the outer layer of each single-phase superconducting cable is wrapped with a shielding layer; a shielding layer connector is arranged on the outer side of each shielding layer; the every two adjacent shielding layer connectors are connected through one metal soft wire, and one shielding layer connector is grounded through a ground wire; the included angle between the every two adjacent metal soft wires is 60 degrees; the metal soft wires are not crossed. According to the triangular shielding layer, the problems that shielding layers of superconducting cables need to be connected in a wire distribution box to form a current loop but a connecting mode at present is complicated in structure, the resistance in a shielding layer loop is relatively large and the shielding effect is relatively bad in the prior art, are solved; the triangular shielding layer provided by the invention is simple in structure, convenient and quick to connect and relatively good in shielding effect.
Description
Technical field
The present invention relates to a kind of three-phase hyperconductive cable, particularly relate to a kind of three-phase hyperconductive cable triangle screen.
Background technology
Current superconductive cable screens layer needs to be interconnected to form current circuit in coupling box, but current connected mode complex structure, and the resistance in screen loop is comparatively large, and shield effectiveness is poor.
Summary of the invention
