可控硅在家用电器以及自动控制系统中应用较广,但由于一般维修人员缺乏必要的检测设备,往往只靠万用表测量其阻值判别其好坏,很难鉴别出其性能的优劣。本文介绍一个小装置,可以很直观地判别出可控硅的好坏和性能的优劣。装置原理如图1所示。
SCR is widely used in household appliances and automatic control systems. However, due to the lack of necessary testing equipment for general maintenance personnel, it is often difficult to identify the pros and cons of its performance by measuring the resistance of the SCR only by using a multimeter. This article describes a small device that can be very intuitive to determine the merits of SCR and performance advantages and disadvantages. Device principle shown in Figure 1.
