摘要:
转换设备是高速道岔重要设备之一，其自动开闭器用于控制转换设备的动作，并表示道岔实际位置，对行车安全至关重要。排弧接点在道岔转辙设备中起着至关重要的作用，其形式就相当于自动开闭器。文章通过对排弧接点的结构、工作过程以及原理进行分析，选用了悬臂叠加弹簧的结构。通过理论计算验证了排弧接点设计的合理性，并进行实际测试计算分析了排弧接点表示闪断的原因，最后提出了排弧接点质量保证的方法。
Abstract:
Conversion equipment is one of the important equipment of high-speed turnout. Its automatic switcher is used to control the action of conversion equipment and indicate the actual position of the turnout, and is very important to driving safety. The arc eliminating contact point plays an important role in the switching equipment, equivalent to the automatic switcher. In the paper, through the analysis of structure, working process and principle of the arc eliminating contact point, the cantilever-spring structure is selected. The theoretical calculation has verified the rationality of the design of arc eliminating contact point. The flashover cause of arc eliminating contact point is analyzed through the actual test calculation. This paper finally puts forward quality assurance method for the arc eliminating contact point.
