REU610CVVHCNR REU610 电压继电器

REU610是 ABB Relion®产品家族中的610 产品系列的成员。该系列包括用于馈线保护、电动机保护和常规系统电压监视的保护装置。插入式设计有利于开关设备的调试，并且保证了插件的快速、安全插拔。

REU610 用于配电站母线过压和低压保护、馈线和变压器过压保护、电动机低压保护以及电容器组的保护和监视。在中性点不接地电力系统中，基于零序电压测量，REU610也可用于无选择性接地故障保护。REU610 用于变电站母线电压自动转换初始化时，将小型动力装置与公共网络断开，即孤岛效应。

为何选择ABB？

• 公用和工业应用的专用保护
• 已通过KEMA认证
• 其在海洋和离岸区域的使用，已通过挪威船级社的认证
• 610系列结构紧凑，可满足于改型和小空间
• 可拆卸插入式设计，允许快速和简单的日常维护

继电器的使用

REU 610电压继电器是一种多功能保护继电器，主要用于过压和欠压保护以及中压配电网络的监督。该继电器还可用于保护发电机、电动机和变压器。
该继电器基于微处理器环境。自我监控系统持续监控继电器的运行。
HMI包括一个液晶显示器(LCD)，这使得继电器的本地使用既安全又容易。
通过串行通信对继电器进行本地控制，并将计算机连接到前端通信端口。后方连接器通过串行通信总线连接到控制和监控系统，可进行远程控制。

Use of the relay

The voltage relay REU 610 is a versatile multifunction protection relay mainlydesigned for overvoltage and undervoltage protection and for supervision ofmedium voltage distribution networks. The relay can also be used for protectinggenerators, motors and transformers.
The relay is based on a microprocessor environment. A self-supervision systemcontinuously monitors the operation of the relay.
The HMI includes a liquid crystal display (LCD) which makes the local use of therelay safe and easy.
Local control of the relay via serial communication can be carried out with acomputer connected to the front communication port. Remote control can be carriedout via the rear connector connected to the control and monitoring system throughthe serial communication bus.
