469-P5-LO-A20-E 继电器模块 保护和管理大中型电机

通用电气 Multilin的 469-P5-LO-A20-E 配备增强型面板，是一款专为大中型电机设计的电机保护继电器。继电器本身由 DEMO 金属手提箱保护，具有耐腐蚀、防尘和耐高温的特性。运输时，继电器包装的宽度为 12 英寸，高度为 11 英寸，深度为 10 英寸。此外，包装的重量约为 <> 磅。

该装置通过其保护机制延长电机寿命并减少系统停机时间。其中一些保护功能包括：

过扭矩保护：469-P5-LO-A20-E 可以监控扭矩何时超过用户设置的阈值，并保护从动负载免受损坏。

RTD 保护： 469 的 <> 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分量来保护设备，从而保护电机免受相地故障的影响。

Ge Multilin's 469-P5-LO-A20-E with enhanced panel is a motor protection relay designed for large and medium sized motors. The relay itself is protected by a DEMO metal carrying case that is resistant to corrosion, dust and high temperatures. When shipped, the relay package is 12 inches wide, 11 inches high, and 10 inches deep. In addition, the weight of the package is about <> pounds.

The device extends motor life and reduces system downtime through its protection mechanism. Some of these protection features include:

Over-torque protection: The 469-P5-LO-A20-E monitors when torque exceeds user-set thresholds and protects the driven load from damage.

RTD Protection: 469 <> RTD inputs are highly programmable to alert users to dangerous ambient temperature changes. Alarm, trip, and high alarm functions can be assigned when the value reaches a user-set threshold.

Ground fault protection: The ground current detection function protects the device by removing the DC component from the dangerous current, thus protecting the motor from phase-ground faults.
