摘要
介绍了控制与保护开关(CPS)触头灭弧系统的各种出厂调试方法以及调试现象。阐述了触头灭弧系统的工作原理,分析了触头灭弧系统的触头受力情况,针对分断试验过程中出现的三种情况,分析了其对KBO触头灭弧系统短路分断能力的影响,通过试验验证了理论分析的正确性,并对触头灭弧系统的调试提出了建议。
Introduction was made to various kinds of ex-works debugging methods and debugging phenomena for contact arc extinguish- ing system of control and protective switching device （CPS）. Description was made to the working principle of contact arc extinguishing sys- tem and analysis was made to contact stress situation of the system. Aiming at three situations in breaking test process, this paper analyzed its impacts on short-circuit breaking capability of KBO contact arc extinguishing system. The test verifies the correctness of theoretical analysis and suggestions are made for debugging of contact arc extinguishing system.
