产品概述
逆功率继电器主要是用于燃汽轮机——发电机组,保护燃汽轮机。当主汽门误关闭或机组保护误动作主汽门关闭,发电机变成电动机运行状态,此状态下由于汽轮机主汽门关闭,汽轮机低压汽缸排汽温度升高,汽轮机尾部叶片将出现过热,造成汽轮机事故。为了防止此类事故,装设本继电器经过一定的延时后,使机组与系统解列。
JX-1信号继电器工作原理
为静态型继电器,采用集成电路构成。被测量的交流电流I~经隔离变流器后,在其次级得到与被测、电流成正比的电压Ui。经定值整定后进行整流,整流后的脉冲电压经滤波器滤波,得到与Ui成正比的直流电压Uo。在电平检测中Uo与直流参考电压Ue进行比较,若直流电压Uo 低于参考电压,电平检测器输出正信号,驱动出口继电器,继电器处于动作状态,反之,若直流电压Uo 高于参考电压Ue,电平检测器输出负信号,本继电器处于不动作状态。
