摘　　要：笔者以FLN44型负荷开关为例,通过对其灭弧原理的介绍,给出了影响负荷开关开断和关合性能的机械特性的简单解释,对分、合闸速度和同期性参数进行了详细的研究分析,提供了一些有价值的经验数据。文中提出了负荷开关25%速度区间的概念,并就具有"弧触头"结构不同期性的测量和判断给出了说明。研究结论可供同类产品的研发和制造参考和借鉴。Taking FLN44 type switch for example, this papers gives a simple explanation of mechanical characteristics through the introduction of its arc-extinguishing principle, which have important impacts on the making and breaking capacity of the switch. It focuses on the analysis of opening and closing speed and its synchronism, by putting forward 25% speed range concept for the first time, estimating the measurement of simultaneity. The research results can provide references for R D and manufacture of other similar products.
