>>>>>型号:469-P1-HI-A20-E 控制电源型号 大型电机系统
【功能描述】
GE Multilin 469 系列的这种增强型号能够保护和控制中型到大型电机系统。469-P1-HI-A20-E-H 与大多数型号不同,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、高温等的影响。因此,保形涂层延长了电机寿命,尤其是在危险的操作环境中。
469-P1-HI-A20-E-H 的增强型面板可分为大约四个部分:包括用于直接连接到运行 EnerVista 469 的笔记本电脑的 RS232 端口、用于输入和编辑设定值的重新设计的键盘、扩展的 40 字符液晶显示屏以及表示系统内各种状态的 LED。
1-P1-HI-A469-E-H 型号中的“P20”表示继电器与 1 A 相 CT 次级兼容。与以“P5”型号表示的 5 A 相 CT 次级相比,用户应确保标称相电流额定值与所有连接的 CT 的连接和次级额定值相对应。 不匹配的 CT 会随着时间的推移对系统造成损坏,并且即使这种损坏不会立即变得明显,也无疑会导致保护减弱。
该继电器还能够进行自我评估,评估电机健康状况,并提供可配置的警报,以便在出现转子问题时提醒用户。 这种早期检测系统除了减少停机时间外,还缩短了故障排除时间。与电机健康相关的指标也可以在通用电气 Multilin 的 EnerVista 469 程序中查看,这比使用键盘手动浏览继电器的菜单更有效。

【英文介绍】
This enhanced version of the GE Multilin 469 series protects and controls medium to large motor systems. 469-P1-HI-A20-E-H Unlike most models, it comes with an optional conformal coating; This thin polymer layer helps protect the device from dust, heat, and more. As a result, conformal coatings extend motor life, especially in hazardous operating environments.
The 469-P1-HI-A20-E-H enhanced panel can be divided into approximately four parts: Includes an RS232 port for connecting directly to a laptop running EnerVista 469, a redesigned keyboard for entering and editing Settings, an expanded 40-character LCD display, and leds for indicating various states within the system.
The "P20" in the 1-P1-HI-A469-E-H model indicates that the relay is compatible with the 1 A-phase CT secondary. In contrast to the 5 A phase CT secondary indicated by the "P5" model, the user should ensure that the nominal phase current rating corresponds to the connection and secondary ratings of all connected CTS. Mismatched CT can cause damage to the system over time, and even if this damage does not become immediately apparent, it will undoubtedly lead to weakened protection.
The relay is also capable of self-assessment, assessing motor health and providing configurable alarms to alert the user if there is a rotor problem. In addition to reducing downtime, this early detection system also reduces troubleshooting time. Indicators related to motor health can also be viewed in GE Multilin's EnerVista 469 program, which is more efficient than manually navigating the relays' menus using a keyboard.
