Abstract
This article is mainly to introduce the structure, principle of operation and characteristic of the plum blossom contact in vacuum circuit-breakers. It also describes the disparities between the plum blossom contact and the duckbill type contact and the ap-plication of the plum blossom contact in this converting station. Plum contact in the power supply system is electrically isolated from the role, but as a result of a high voltage part of its operation in electric power system, so the dynamic stability and thermal stability of pro-duction process and the contact resistance under the high current through have strict requirements.关键词
