Problems solved by technology
The linkage crank arm of the traditional friction disc is fixedly connected with the vertical shaft directly through the flat key (see Figure 5 ), it is impossible to realize the change of the starting and ending positions of the linkage arm. Different three-phase arrangements of isolating switches require different vertical axes and linkage arms

Embodiment Construction
[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0029] Figure 1 to Figure 4 It shows an embodiment of the friction disc structure used in the three-phase linkage of the disconnector according to the present invention. The friction disc structure includes a friction disc weldment 1, a fixed splint 3 and a linkage crank arm 2. The friction disc weldment 1 includes a friction disc 11 and a vertical shaft 12, the friction disc 11 is fixedly connected to the vertical shaft 12, the vertical shaft 12 of the friction disc weldment 1 is inserted into the inner hole of the fixed splint 3, and passes through the bearing seat 4 and is fixedly connected with the base flange 5, friction The disk 11 is embedded in the fixed splint 3, and the fixed splint 3 is detachably connected with the linkage crank arm 2. The linkage crank arm 2 presses the friction disc 11 into the fixed splint 3 . The li...

The invention relates to a friction disc structure and a connection operating method for an isolation switch and the same. The friction disc structure comprises a friction disc welding piece and a linkage crank arm, wherein the friction disc welding piece comprises a friction disc and a vertical shaft, the friction disc is fixedly connected with the vertical shaft, the friction disc structure also comprises a fixed sandwiched plate, the vertical shaft of the friction disc welding piece is inserted into an inner hole of the fixed sandwiched plate, the friction disc is embedded into the fixed sandwiched plate, the fixed sandwiched plate is detachably connected with the linkage crank arm, the linkage crank arm is used for pressing the friction disc in the fixed sandwiched plate, and the friction disc is tightly held by the linkage crank arm and the fixed sandwiched plate. The invention also comprises a connection operating method of the friction disc structure and the isolation switch. The friction disc structure has the advantage of simplicity and is convenient to install, and the position of the three-phase linkage crank arm can be arbitrarily changed when the isolation switch is in a breaking-closing state.
Description
technical field [0001] The present invention mainly relates to the technical field of electric power equipment, and relates to a friction disc structure and a method for connecting and operating it with an isolating switch, which is used in a power system with a rated voltage of 220kV and below for high-voltage lines to switch under no current-carrying conditions. It is used on the outdoor high-voltage AC isolating switch for electrical isolation between the high-voltage busbar, circuit breaker and other electrical equipment being overhauled and the live high-voltage line. Background technique [0002] In power transmission and distribution systems, outdoor high-voltage AC disconnectors are widely used. There are many types of disconnectors, and there are various three-phase arrangements, which can be roughly divided into three categories: cross arrangement, parallel arrangement and one-column arrangement. The deviation of the three-phase arrangement and the installation bas...
