Abstract: The ultra high speed isolating switch equipped with effective bumpers could lower the impact during the process of switches making and breaking and improve the insulativity of switches and mechanical life. Combining with the requirements of ultra high speed switch, this paper analyzed the parameter of this high-speed buffer and researched on the gas-liquid damping model. A gas-liquid composite buffer was developed. The performance and prototype tests reach more than 3000 times of life, so that it can meet the demand of ultra high speed switch application.
Key words: high speed isolating switch; impact; composition buffer; liquid damping; performance modeling
