产品描述

GE Multilin的469系列的这种增强模型能够保护和控制中型到大型电机系统。469-P1-HI-A20-E-H也是大多数型号的独特之处，因为它配备了可选的保形涂层;这薄，聚合物层有助于保护单位免受灰尘，高温，和更多。因此，保形涂层延长了电机的使用寿命，特别是在危险的操作环境中。

469- p1 - hi - a20 - e - h的增强面板可以分为大约四个部分:这包括RS232端口，用于直接连接到运行EnerVista 469的笔记本电脑，重新设计的键盘用于设定点输入和编辑，扩展40个字符的液晶显示器，以及表示系统内各种状态的led。

469-P1-HI-A20-E-H的型号中的“P1”表示该继电器与1a相CT次级兼容。与“P5”型号表示的5个A相CT次电流相比，用户应确保标称相电流额定值与所有连接的CT的连接和次电流额定值相对应。随着时间的推移，不匹配的ct可能会对系统造成损害，并且毫无疑问会导致保护减弱，即使这种损害不会立即变得明显。

该继电器还能够自我评估，评估电机健康，并提供可配置的警报，提醒用户当转子问题出现。这种早期检测系统减少了故障排除时间，减少了停机时间。与电机健康相关的指标也可以在通用电气Multilin的EnerVista 469程序中进行检查，这比使用键盘手动导航继电器菜单更有效。

Product description

This enhanced model from GE Multilin's 469 series protects and controls medium to large motor systems. The 469-P1-HI-A20-E-H is also unique to most models as it comes with an optional conformal coating; This thin, polymeric layer helps protect the unit from dust, heat, and more. As a result, conformal coatings extend the service life of the motor, especially in hazardous operating environments.

The 469-P1-HI-A20-E-H's enhanced panel can be divided into approximately four parts: This includes an RS232 port for direct connection to a laptop running EnerVista 469, a redesigned keyboard for set point input and editing, an expanded 40-character LCD display, and more. And leds that indicate various states within the system.

The "P1" in the model number of 469-P1-HI-A20-E-H indicates that the relay is compatible with the 1a phase CT secondary. In contrast to the five A-phase CT subcurrents indicated by the "P5" model, the user should ensure that the nominal phase current rating corresponds to the connection and subcurrent ratings of all connected CT's. Over time, a mismatched ct can cause damage to the system and will undoubtedly lead to weakened protection, even if this damage does not become immediately apparent.

The relay is also capable of self-assessment, assessing motor health, and providing configurable alarms to alert users when rotor problems arise. This early detection system reduces troubleshooting time and reduces downtime. Indicators related to motor health can also be checked in GE Multilin's EnerVista 469 program, which is more efficient than manually navigating the relay menu using a keyboard.
