摘要:

大容量交流接触器使用时负载电流大、功率因数小、电弧熄灭时能量大,对灭弧系统要求高。通过理论分析、高速摄影和电寿命试验等方法研究不同触头系统和灭弧系统的灭弧能力,为提升大容量交流接触器电寿命和使用可靠性提供参考。

关键词: 大容量, 交流接触器, 灭弧系统, 电寿命

Abstract:

Big-capacity AC contactors have a high requirement on the arc extinction system due to a large load current,small power factor and high energy when the arc is extinguished.Through theoretical analysis,high-speed photography and electrical life testing,the arc extinguishing ability of different contact systems and arc extinguishing systems is studied,which can provide the reference for improving the electrical life and reliability of large capacity AC contactors.

Key words: big-capacity, AC contractor, arc extinction system, electrical lifetime
