新型可控硅觸發(fā)器CF6B-2A在擠塑機(jī)中的應(yīng)用

摘要：介紹了雙閉環(huán)可控硅觸發(fā)器CF6B-2A的工作原理，并將該器件應(yīng)用于擠塑機(jī)主驅(qū)動(dòng)電動(dòng)機(jī)控制系統(tǒng)中。試驗(yàn)結(jié)果表明，以該觸發(fā)器為控制核心的脈沖信號(hào)發(fā)生與控制裝置具有結(jié)構(gòu)簡(jiǎn)單、調(diào)節(jié)方便、性能可靠、造價(jià)低等特點(diǎn)。 敘詞：可控硅觸發(fā)器；移相；雙閉環(huán) Abstract：The working principle of a new double closed-loop thyristor trigger CF6B-2A and its application in the control system of driver motor in the extruder were introduced. The test results show that the pulse signal generate and control device based on this type of trigger has characteristics of simple, easier operation, higher precision, lower cost and so on.
