469-P1-HI-A20-E 应用于综合保护继电器 GE 通用电气

产品说明

通用电气公司469系列的这一增强型模型能够保护和控制中型到大型的电动机系统。大多数型号的469-P1-HA-20-EH也是独一无二的因为它具有可选的共形涂层;这种薄的聚合层有助于保护单位免受灰尘、高温等的影响。因此,共形涂层可以延长电动机的寿命,特别是在危险的操作环境中。

该469-P1-HA-20-EH的增强面板可分为大约四个部分:这包括用于直接连接运行中的一台笔记本电脑的RS232端口、重新设计的设置点输入和编辑键盘、一个扩展的40字符液晶显示器,以及表示系统内各种状态的LED。

469-P1.H1-4-20-EH模型中的"P""表明:继电器与1A级CT二级兼容.与"P-5"模型编号所表示的5A级CT二级相比,用户应确保名义相位电流等级与所有连接的CTS的连接和二级等级一致。不匹配的CTS会在一段时间内对系统造成破坏,并且毫无疑问地会导致保护的减弱,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,评估电动机的健康状况,并提供可配置的警报,以提醒用户出现转子问题。这种早期检测系统除了减少停机时间外,还减少了故障排除时间。

Product description

This enhanced model from GE's 469 series protects and controls medium to large motor systems. Most models of 469-P1-HA-20-EH are also unique in that it has an optional conformal coating; This thin polymer layer helps protect the unit from dust, high temperatures, etc. As a result, conformal coatings can extend the life of the motor, especially in dangerous operating environments.

The 469-P1-HA-20-EH's enhanced panel can be divided into approximately four parts: This includes an RS232 port for connecting directly to a running laptop, a redesigned setup point input and editing keyboard, an expanded 40-character LCD display, and leds for indicating various states within the system.

The "P" in the 469-P1.H1-4-20-EH model indicates that the relay is compatible with Class 1A CT Level 2. In contrast to the 5A CT Level 2 indicated by the "P-5" model number, the user should ensure that the nominal phase current level is consistent with the connection and level 2 of all connected CTS. Mismatched CTS can cause damage to the system over a period of time and will undoubtedly lead to a weakening of protection, even if this damage does not become immediately apparent.

The relay is also capable of self-assessment, assessing the health of the motor and providing configurable alarms to alert the user to rotor problems. In addition to reducing downtime, this early detection system also reduces troubleshooting time.
