断路器的旋转式互联双动触头接触系统设计

Design of Rotary Interconnected Double Moving Contact Contact System for Circuit Breaker

摘要:

文中设计了一种断路器的旋转式互联双动触头接触系统，包括可转的安装在底座上的主动触头组件和从动触头组件，主动触头组件和从动触头组件构造成驱动连接。主动触头组件在外力作用下带动从动触头组件分别沿彼此相向方向转动，以使其触头彼此接触；主动触头组件和从动触头组件在其各自复位件的作用下同时沿彼此相反方向转动，以使其触头分开。所设计的旋转式互联双动触头机构闭合和断开速度快，有利于快速灭弧、耐压能力提高，具有广泛的应用前景。

Abstract:

A rotary interconnected double moving contact contact system of circuit breaker is designed, including a driving contact assembly and a driven contact assembly rotatably mounted on a base, and the driving contact assembly and the driven contact assembly are configured to be driven and connected. Under the action of external force, the driving contact assembly drives the driven contact assembly to rotate in the opposite direction to make the contacts contact each other, while the driving contact assembly and the driven contact assembly rotate in the opposite direction to separate the contacts under the action of their respective reset parts. The designed rotary interconnected double moving contact mechanism has a fast closing and breaking speed, which is conducive to rapid arc extinguishing and improvement of voltage withstand capacity, and has a wide application prospect.
