摘要
介绍一种自行研制开发的WRJB 45 380型微电脑控制电机多功能节电保护器,该装置是一个微电脑控制的相位、电流双闭环反馈系统。由晶闸管自动跟踪供电,能随时跟踪负载的变化大小,自动调节供电电压;避免电能的浪费,大大提高电机运行效率,最大限度地提高了电机的有功功率的比率,并且具有短路、过载度保护功能,真正做到一机多用,是电机理想的控制设备。该节能装置是企业能量降损、提高经济效益的理想选择,可广泛应用在石油、橡胶、冶金、矿山等领域,具有良好的市场前景,其经济效益也是相当可观的。
A self-developed multi-functional brownout protector (MD WRJB-45/380) controlled by microcomputer.The product is a microcomputer controlled,and bi-closed-loop current feedback system.The silicon in it can automatically trake and supply the power.It also can trake the changing size of the load and supply the electric energy.Therefore, it can avoid wasting electric energy and greatly maximum the rate of the active power.Moreover,it has the protective function of short circuit and over-loading protection.It is really a multi-functional machine and an ideal controlling device of the electrical machinery.
