Embodiment Construction

[0020] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 , 2 As shown in and 3, the present invention provides a closing buffer mechanism for high-speed switches, including a frame 1 connected to the housing of the high-speed switch, a buffer mechanism and an adjustment mechanism are arranged on the frame 1, and the adjustment structure It is used to adjust the input position of the buffer mechanism in the closing stroke. The buffer mechanism is used to buffer the closing process, which can solve the problems of buffering speed reduction and energy dissipation in the short high-speed movement stroke of the switch, so that the moving contact The head realizes high-speed approach to the static contact and low-speed collision, thereby realizing controllable closing time, reliable closing, small bounce, and improved mechanical operation life. The overall structure is modular and...

Abstract

The invention relates to the technical field of high-voltage devices. The closing buffer mechanism for the high-speed switch comprises a rack connected with a shell of the high-speed switch, a buffermechanism and an adjusting mechanism are arranged on the rack, the adjusting mechanism is used for adjusting the input position of the buffer mechanism in the closing stroke, and the buffer mechanismis used for buffering the closing process. The closing buffer structure is simple, reliable and convenient to apply, and has good market popularization value.

Description

technical field [0001] The invention relates to the technical field of high-voltage devices, in particular to a closing buffer mechanism and an adjustment method for high-speed switches. Background technique [0002] In high-voltage power equipment, especially in the field of DC power transmission and distribution, rapid action can greatly shorten the duration of faults, quickly restore the power system, significantly improve the stability and adaptability of the power system, significantly reduce the operating cost of the power grid, and facilitate intelligent control . Due to the complex transmission structure of traditional switchgear, it is difficult to meet the above requirements. The high-speed mechanical switch came into being, with its simple transmission chain and unique driving method, it can realize millisecond-level action. [0003] Due to the fast movement of high-speed mechanical switches, on the one hand, it is necessary to reduce the inertia of moving parts...
