高气压电弧状态转换规律的蝴蝶型突变模型

Gaoya dianqi, 1999
阐明了高气压条件下（0.1MPa及以上）电器开断电路过程中触头间金属蒸汽电弧和气体电弧及其转换这一物理事实;根据金属蒸汽电弧向气体态电弧转换的规律和条件,应用基本突变理论,建立的反映电弧状态转换规律的蝴蝶型突变模型,使得预见和控制电弧转换成为可能.

PTFE蒸气对电弧特性影响的数值分析

Gaoya dianqi, 2002
在喷口电弧动态数学模型中 ,考虑了喷口烧蚀产生的PTFE蒸气的作用。应用有限元方法模拟了SF6 自能膨胀式断路器开断短路电流的过程。通过与不考虑PTFE蒸气影响的开断过程的模拟结果相比较 ,得到了PTFE蒸气对喷口电弧特性影响的结果。表明 :PTFE蒸气使喷口电弧的压力明显增高 ;使电流较高时的电弧温度降低 ;使电弧电流过零时的弧区温度升高 ;在电弧电流下降时 ,电弧的温度下降速度变慢 ;使电弧的半径增大。
