Abstract
The utility model discloses a large-current isolating switch for urban rail transit, which comprises a base, a first support and a second support are respectively arranged on the base, the first support and the second support are respectively connected with the base through insulators, a first wire outlet plate is arranged at the upper end of the first support, and a second wire outlet plate is arranged at the upper end of the second support. A connecting rod is connected to the main shaft, one end of the connecting rod is rotationally connected with one end of the insulating pull rod, the other end of the insulating pull rod is rotationally connected with the isolation knife assembly, and the other end of the connecting rod is rotationally connected with one end of the transmission rod; the rotating motion of the isolation knife assembly is converted into the push-pull motion of the transmission rod, so that the opening and closing convenience of the isolation knife assembly is improved, and the use condition that the isolation switch is opened and closed for multiple times in rail transit is adapted.
