REF620E_F 馈线保护装置 拓展新行业 

REF620 IEC 馈线保护和测控装置，作为专用馈线保护装置，专门用于保护、控制、测量和监视公共和工业电网，包括辐射，环形和网状电网。REF620 提供馈线过流和接地故障保护，该保护可应用于中性点不接地网络和电阻或阻抗中性点接地网络。此外，利用装置先进的站级间通信功能，REF620 也可以用于环形网状配电网络或辐射网络保护。

REF620 IEC 馈线保护和测控装置有单母线和双母线两种配置可选，每种母线配置又有一个或两个断路器及多个开关装置配置可选。装置支持大量手动和电动隔离开关和接地开关。可用 I/O 的数量可根据ABB的 RIO600 远方 I/O 装置的需要而增加。

REF620 IEC 馈线保护和测控装置以支持变电站 IEC61850 通信标准为特点，涵盖垂直和水平通信，包含带开关量信号和模拟量信号的 GOOSE 报文以及基于 IEC 61850-8-1 的定值整定。REF620 还支持 DNP3, IEC 60870-5-103 和 Modbus® 规约。REF620 通过 PRP 或 HSR 规约在通信故障时为无延时的冗余以太网提供一个可选以太网口或提供一个环网自愈 RSTP 通信。该解决方案消除了单点故障影响，提高了通信可靠性。该解决方案可以应用到基于以太网的 IEC 61850, Modbus® 和 DNP3 规约。

REF620 是 ABB Relion® 产品家族中的 620 保护测控装置产品系列的成员。

REF620E_F 馈线保护装置 拓展新行业 

The REF620 IEC Feeder Protection and Measurement and control device is a dedicated feeder protection device specifically designed to protect, control, measure and monitor public and industrial power grids, including radiant, ring and mesh power grids. The REF620 provides feeder overcurrent and ground fault protection, which can be applied to neutral ungrounded networks and resistance or impedance neutral ground networks. In addition, the REF620 can also be used for ring mesh distribution networks or radiation network protection, using the device's advanced interstation communication capabilities.

The REF620 IEC feeder protection and measurement and control devices are available in single and dual bus configurations, with one or two circuit breakers and multiple switchgear configurations available for each bus configuration. The device supports a large number of manual and electric isolation switches and ground switches. The amount of available I/O can be increased according to the needs of ABB's RIO600 remote I/O devices.

The REF620 IEC feeder protection and measurement and control unit features support for the substation IEC61850 communication standard, covering vertical and horizontal communication, GOOSE messages with switching and analog signals, and set setting based on IEC 61850-8-1. The REF620 also supports DNP3, IEC 60870-5-103, and Modbus® protocols. The REF620 provides an optional Ethernet port for redundant Ethernet without delay or a ring self-healing RSTP communication in the event of a communication failure via PRP or HSR protocols. This solution eliminates the single point of failure and improves communication reliability. The solution can be applied to Ethernet-based IEC 61850, Modbus® and DNP3 protocols.

The REF620 is a member of ABB's Relion® product family of 620 protective measurement and control devices.
