Abstract
- It is of great significance to achieve good cooperation between the fast vacuum switch driven by the electromagnetic repulsion mechanism and the buffer system. The purpose of this paper is to study the cooperation of the 40.5kV fast vacuum switch driven by the electromagnetic repulsive mechanism and the oil damper. Firstly, the dynamic characteristics of the electromagnetic repulsion mechanism during the opening process were simulated by MAXWELL software. Then, based on the dynamic characteristics of the electromagnetic repulsive mechanism, a simplified model of the oil buffer is established by AMESim software and its cushioning characteristics are simulated. Moreover, the influence of the buffer piston area and the annular gap width on the cushioning characteristics of oil buffer is analyzed. Finally, the dynamic characteristics of the electromagnetic repulsion mechanism under the action of the oil damper are simulated and analyzed. It provides some guidance for the cooperation of the fast vacuum switch driven by the electromagnetic repulsive mechanism and the oil damper.
