产品说明
GE Multilin 469系列的这种增强型号能够保护和控制大中型电机系统。469-P1-嗨-A20-E-H在大多数型号中也是独一无二的，因为它带有可选的保形涂层；这种薄的聚合物层有助于保护设备免受灰尘、高温等影响。因此，保形涂层延长了电机寿命，尤其是在危险的工作环境中。
469-P1-嗨-A20-E-H的增强型面板可分为大约四个部分:这包括用于直接连接运行EnerVista 469的笔记本电脑的RS232端口、用于设定点输入和编辑的重新设计的键盘、扩展的40字符液晶显示器以及表示系统内各种状态的led。
469-P1-嗨-A20-E-H的型号中的“P1”表示继电器与1 A相CT次级兼容。与型号为“P5”的5 A相电流互感器二次相比，用户应确保额定相电流与所有连接电流互感器的连接和二次额定值一致。随着时间的推移，不匹配的电流互感器会对系统造成损害，并且无疑会导致保护功能减弱，即使这种损害不会立即变得明显。
该继电器还能够进行自我评估，评估电机健康状况，并在转子出现问题时提供可配置的警报来提醒用户。这种早期检测系统不仅减少了停机时间，还减少了故障排除时间。与电机健康相关的指标也可以在通用电气多线的EnerVista 469程序中查看，这比使用键盘手动浏览继电器菜单更有效。

Product Description
This enhanced model of GE Multilin’s 469 series is able to protect and control motor systems of medium to large size. The 469-P1-HI-A20-E-H is also unique from most models in that it comes with the optional conformal coating; this thin, polymeric layer helps protect the unit from dust, high temperatures, and more. The conformal coating therefore extends motor life, especially in hazardous operating environments.
The 469-P1-HI-A20-E-H’s enhanced faceplate can be divided into approximately four sections: this includes the RS232 port for direct connection to a laptop running EnerVista 469, the redesigned keypad for setpoint entry and editing, an expand 40-character liquid-crystal display, and the LEDs which signify various statuses within the system.
The “P1” in the model number of the 469-P1-HI-A20-E-H indicates that the relay is compatible with 1 A phase CT secondaries. Contrasting with the 5 A phase CT secondaries denoted by “P5” model numbers, users should ensure that the nominal phase current rating corresponds with the connections and secondary ratings of all connected CTs. Mismatched CTs can cause damage to the system over time, and will indubitably result in weakened protection even if this damage does not immediately become evident.
This relay is also capable of self-assessment, evaluating motor health, and offering configurable alarms to alert users when rotor problems arise. This early detection system results in reduced troubleshooting times in addition to reduced downtime. Metrics related to motor health can also be reviewed in General Electric Multilin’s EnerVista 469 program, which is more efficient than manually navigating through the relay’s menus using the keypad.
