Abstract
The invention provides an isolation switch of a distribution system. The isolation switch comprises an insulator. The insulator is composed of an upper part and a lower part, wherein the two parts are symmetrically arranged. The upper and lower parts of the insulator are respectively provided with an umbrella skirt. The right side of the part between the upper and lower parts of the insulator is connected with a mounting plate. The upper and lower ends of the insulator are respectively provided with an upper connecting piece and a lower connecting piece. The left sides of the upper and lower connecting pieces are connected with a terminal plate, respectively. An isolation blade is arranged between the two terminal plates. The upper end of the isolation blade is provided with a support elastic sheet, and the lower end of the isolation blade is provided with a locking mechanism. The lower end of the left side of the upper connecting piece is connected with a load cut-off lifting hook. According to the technical scheme of the isolation switch, the insulator is connected with the terminal plates to realize the arrangement of the isolation blade. The mounting plate arranged at the middle part of the insulator is connected with an electric pole installation bracket to realize the installation. In this way, the isolation switch is small in size and can be well adapted to the switching-on/off operation for the circuits of power distribution systems that are 27 kV or smaller in voltage.
