晶闸管变流技术是电能的变换,包括电压、电流和频率的变换,主要用于可控整流、逆变、斩波、变频、开关等,其最重要的特性是正向导通的可控性。文章分析了直流调速电动机检修后无法正常运转的问题,得出原因是主变压器TR与同步变压器TS所接的相序不同步,导致可控整流装置无法正常工作,因此在晶闸管变流技术中主电路与控制电路必须保持同步。
Thyristor converter technology is the transformation of electrical energy, including voltage, current and frequency conversion, mainly for controllable rectifier, inverter, chopping, frequency conversion, switching, the most important feature is the controllability of the forward conduction. The article analyzes the problem that the DC motor can not operate normally after overhauling the motor and concludes that the reason is that the phase sequence of the main transformer TR and the synchronous transformer TS is not synchronized and the controllable rectifying device can not work normally. Therefore, in thyristor converter technology Main circuit and control circuit must be kept in sync.
