产品描述
配备增强型面板,通用电气Multilin的469-P5-LO-A20-E是一种电机保护继电器,专为大中型电机设计。继电器本身由DEMO金属手提箱保护,具有耐腐蚀、防尘、耐高温等特点。发货时,继电器包装宽度为12英寸,高度为11英寸,深度为10英寸。此外,这个包裹的重量约为17磅。
该装置通过其保护机制延长了电机寿命,减少了系统停机时间。这些保护功能包括:
过扭矩保护:当扭矩超过用户设置的阈值时,469-P5-LO-A20-E可以监控,并保护驱动负载免受损坏。
RTD保护:469的12个RTD输入是高度可编程的,可以提醒用户危险的环境温度变化。当值达到用户设置的阈值时,可以分配报警,跳闸和高报警功能。
接地故障保护:接地电流检测功能通过从危险电流中移除直流组件来保护电机免受相接地故障的影响,以保护设备。
除其他保护功能外,这些功能减少了系统停机时间并延长了电机寿命。
469具有模拟功能,允许它测试继电器的有效性,并评估它如何与当前设定值设置一起工作。数值模拟输入;故障条件和预跳闸条件也可以模拟。

Product description
Equipped with an enhanced panel, GE Multilin's 469-P5-LO-A20-E is a motor protection relay designed for large and medium sized motors. The relay itself is protected by DEMO metal carrying case with corrosion resistance, dust resistance and high temperature resistance. When shipped, the relay package is 12 inches wide, 11 inches high, and 10 inches deep. In addition, the package weighs about 17 pounds.
The device extends motor life and reduces system downtime through its protection mechanism. These protection features include:
Overtorque protection: The 469-P5-LO-A20-E monitors and protects the drive load from damage when the torque exceeds a user-set threshold.
RTD Protection: The 469's 12 RTD inputs are highly programmable to alert users to dangerous ambient temperature changes. When the value reaches the threshold set by the user, alarm, trip and high alarm functions can be assigned.
Ground fault protection: The ground current detection function protects the motor from a contact ground fault by removing the DC component from the dangerous current.
Among other protective features, these reduce system downtime and extend motor life.
The 469 has simulation capabilities that allow it to test the effectiveness of the relay and evaluate how it works with the current set point Settings. Numerical simulation input; Failure conditions and pre-trip conditions can also be simulated.
