REF620是一款专用馈线保护装置,专门用于保护、控制、测量和监视公共和工业配电系统,包括辐射、环形和网状电网。
它提供馈线过流和接地故障保护,这种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。
REF620具有先进的站级间通信功能,可以用于环形网状配电网络或辐射网络保护。装置支持大量手动和电动隔离开关和接地开关,且其I/O数量可根据ABB的RIO600远方I/O装置的需要而增加。
REF620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。它还支持DNP3、IEC 60870-5-103和Modbus®规约。
REF620还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。同时,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,提高了通信可靠性。
The REF620 is a purpose-built feeder protection device designed to protect, control, measure and monitor public and industrial power distribution systems, including radiant, ring and mesh grids.
It provides feeder overcurrent and ground fault protection, which can be applied to neutral ungrounded networks and resistance or impedance neutral ground networks.
The REF620 features advanced interstation communication and can be used for ring mesh distribution networks or radiation network protection. The device supports a large number of manual and electric isolation switches and ground switches, and the number of I/ OS can be increased according to the needs of ABB's RIO600 remote I/O devices.
The REF620 features support for the IEC61850 communication standard for substations, covering vertical and horizontal communication, GOOSE messages with switching signals and analog signals, and fixed setting based on IEC 61850-8-1. It also supports DNP3, IEC 60870-5-103, and Modbus® protocols.
The REF620 is also available in single and dual bus configurations, with one or two circuit breakers and multiple switchgear configurations for each bus configuration. At the same time, the REF620 improves communication reliability by providing an optional Ethernet port for redundant Ethernet without delay or a ring self-healing RSTP communication in the event of a communication failure through PRP or HSR protocols.
