The invention relates to a
floor type isolated switch cabinet for an
overhead line system. The
floor type isolated switch cabinet comprises a stainless steel sealed box, wherein the interior of the stainless steel sealed box is divided into an upper part and a lower part through a partition plate; the upper part is a high-
voltage chamber, and the lower part is a control chamber; an
air insulation inner cone slide-in cable socket, an electric isolating switch and a supporting insulator are installed in the high-
voltage chamber; an electric / manual operating mechanism, an
overhead line system isolating switch monitoring device and a high-
voltage charged sensor are arranged in the control chamber. The
floor type isolated switch cabinet disclosed by the invention is mainly applied to circuits among various sectioned power supply parts in an electrified railway on-off
overhead line system in a strong wind area, the power supply flexibility is increased, potential safety hazards are eliminated, the switch body is filled in the closed box, the box is installed at the column bottom, the strong
wind speed-increasing area is avoided, sand
erosion is avoided, and the reliability of equipment operations is comprehensively improved.
