一种经济型小体积单腔体PC级ATSE接通与分断能力优化设计

Optimal Design of Making and Breaking Capacity of PC Level ATSE withEconomical Small Volume and Single Cavity

针对一种常用触头、备用触头均在一个腔体内的PC级经济型自动转换开关(ATSE),详细介绍了产品结构原理,并对操作机构进行优化。具有快速分断和接通的带储能操作机构,通过储能结构带动旋转轴运动,可有效降低动静触头上的接触电阻,而环型灭弧栅片能达到有效引弧、灭弧的作用。结合试验摸索对I型静触头改为Y型静触头来提高接通与分断性能指标,同时触头系统采用极数自由拼装设计,安装便捷。

The PC-grade ATSE refers to the economical one,with common contacts and spare contacts in a cavity.It operates by the mechanism,that can quickly disconnect and connect,to effectively reduce the contact resistance on the moving and static contacts by driving the rotating shaft through the energy storage structure.The arcing grid piece of it can effectively control the voltaic arcs.Through experiments and trials,the I-type static contact is changed to the Y-type one to improve the performance index of making and breaking capacity.In the meanwhile,the ATSE contact system adopts the freely assembled design of pole numbers,which is convenient to install.This paper introduced the structure principles of the product and detailed the optimization of its operating mechanism.
