摘要
本文从理论上分析了继电器触点间电弧产生的原因及消弧措施。为了提高ＰＣ控制系统的可靠性，必须保护ＰＣ输出继电器的触点。
t is known that when the inductive load is opened, the electric arc may be produced between the contacts of relay. Its producing reason is theoretically expounded and the preventive measures to eliminate its production are proposed.In cider to increase the reliability of programmable controller the protection of its output contacts should be taken.
