本文介绍一种采用可控硅元件组成的液位自动词节装置,代替传统的交流接触器部分。由于可控硅元件没有易磨损的可动部分,因而使调节仪具有线路简单、使用可靠、寿命长、维修方便等特点。适应于化工、化肥生产中简单的液位位式调节场合。原理线路如附图所示。它主要是由四个可控硅元件T_1～T_4等构成。T_1控制极分别接入检测
This article describes a controllable silicon device composed of liquid level automatic node device, instead of the traditional part of the AC contactor. As the SCR components are not easy to wear and tear of the movable part, so that the regulator has a simple line, the use of reliable, long life, easy maintenance and so on. Adapt to chemical, fertilizer production in a simple liquid level position adjustment occasions. Principle line as shown in the figure. It is mainly composed of four thyristor T_1 ~ T_4 and other components. T_1 control pole access detection
