Introduces the application and structure principle of SSJ-11A type static timing relay, discusses the possible reasons of timing contact snapped of relay, take the detecting methods of timing contact snapped of SSJ-11A type static timing relay for example. 介绍了SSJ-11A型静态时间继电器的应用及构造原理,探讨了时间继电器延时接点瞬动的可能原因,举例说明了SSJ-11A型时间继电器延时接点瞬动的检测方法。
Discussion on Detecting Methods of Timing Contact Snapped of Static Timing Relay 静态时间继电器延时接点瞬动检测方法的探讨
Reversal current chronopotentiometry have to restrict sampling interval. To solve this problem, timing control is applied in electric relay. Timer control which is included in Delphi is used in the program. Program of controlling electric relay is executed every 4 seconds. 为了解决使用电流反向法必须要限制采样间隔的问题,我们对继电器实施定时控制,在编程中使用Delphi中的时钟控件(timer),每4秒钟执行一次程序。
