doi:10.16628/j.cnki.2095-8188.2024.10.008

Abstract

Abstract:

The AC arc characteristic curve is an important basis for evaluating the breaking capacity of switches.The influence of magnetic blowing on AC arc characteristics is analyzed by testing the contact voltage and contact current waveforms during the breaking process of rocker switch.It is confirmed that there are two arc extinguishing mechanisms,which are the mechanical breaking mechanism and the current zero-crossing mechanism.The drawn conclusion is valuable for improving the AC load breaking capacity of rocker switches.

Key words: rocker switch, magnetic blowing, AC arc, POW, arc extinguishing theory
