NOVEL FIXED CONTACT SHARING STRUCTURE

摘要

A combined fixed contact assembly for a high-voltage isolating switch comprises a mounting base (1). A first fixed contact (4) and a second fixed contact (8) connected to corresponding moving contacts, as well as a wiring terminal (2) electrically connected to the first fixed contact and the second fixed contact by a conductive device are mounted on the mounting base through a correspondingly disposed fixing support. Two fixed contacts of the fixed contact assembly are mounted on the mounting base through the fixing support, so that the two fixed contacts are respectively connected to an isolating switch at a polar line anti-flat valve side and to a bypass bus isolating switch, and the two isolating switches share one fixed contact assembly, thereby saving the land resource, increasing the construction speed, shortening the installation period, reducing the investment in the power plant, and reducing the installation and maintenance cost during the power plant construction.
