REF620为配电变电站的架空线路、电缆馈线和母线系统提供主要保护。
适用于接地和不接地配电系统的保护和控制。它提供支持单断路器,一个半断路器和双断路器馈线配置。灵活的订单编码允许选择电流或电流和电压配置,以最适合您的配电馈线应用需求。
REF620是同类产品中功能最强大,最先进,最简单的馈线保护继电器,完美地提供时间和瞬时过流,负序过流,相位步距,相位不连续,断路器故障,热过载以及电压计量和保护。该继电器还具有高阻抗故障(HIZ)和敏感接地故障(SEF)保护接地和不接地配电系统。此外,该继电器还具有灵活的三相多镜头自动关闭功能,可在架空线路临时故障时自动恢复馈线。
增强了安全选项,继电器提供了一个三通道电弧故障检测系统,用于监督开关柜。REF620还集成了基本的控制功能,通过继电器的前面板人机界面(HMI)或远程控制系统,可以方便地控制多达2个断路器。
为了保护中继免受未经授权的访问并保持信息的完整性,中继提供了一个四级、基于角色的用户身份验证系统,并为查看器、操作员、工程师和管理员级别设置了单独的密码。门禁系统适用于前面板HMI、基于嵌入式web浏览器的HMI、PCM600、保护与控制IED管理器。
REF620E_F NBFNAANNNCC1BNN1XF
The REF620 is a dedicated feeder IED perfectly aligned for the protection, control, measurement and supervision of utility substations and industrial power systems. REF620 is a member of ABB’s Relion® family and a part of its 620 protection and control product series. The 620 series IEDs are characterized by flexibility and performance for demanding utility distribution and industrial applications. Engineered from the ground up, the 620 series has been designed to unleash the full potential of the IEC 61850 standard for communication and interoperability of substation automation devices.
Unique REF620 ANSI features
− Six setting groups
− Drawout design
− Underground, overhead cable fault detection (CFD)
− High-speed (< 1 ms) outputs
− High impedance (HIZ) fault detection
− Arc flash detection (AFD)
− Phase step distance protection
− Power quality
− Ring-lug terminals for all inputs and outputs
− Large, easy to read LCD screen
− Programmable push-buttons
− Environmentally friendly design with RoHS Compliance
The REF620 provides main protection for overhead lines, cable feeders, and busbar systems of distribution substations.
It can be applied for protection and control of grounded and ungrounded distribution systems. It offers support for single breaker, one-and-half breaker and double breaker feeder configurations. Flexible order coding allows for choosing current-only or current-and-voltage configurations to best fit your distribution feeder application needs.
The REF620 is the most powerful, advanced and simplest feeder protection relay in its class, perfectly offering time and instantaneous overcurrent, negative sequence overcurrent, phase step distance, phase discontinuity, breaker failure, thermal overload, and voltage metering and protection. The relay also features high impedance fault (HIZ) and sensitive earth fault (SEF) protection for grounded and ungrounded distribution systems. Also, the relay incorporates a flexible three-phase multi-shot auto-reclose function for automatic feeder restoration in temporary faults on overhead lines.
Enhanced with safety options, the relay offers a three-channel arc-fault detection system for supervision of the switchgear. The REF620 also integrates basic control functionality, which facilitates the control of up to 2 circuit breakers via the relay’s front panel human machine interface (HMI) or remote control system.
To protect the relay from unauthorized access and to maintain the integrity of information, the relay has been provided with a four-level, role-based user authentication system, with individual passwords for the viewer, operator, engineer, and administrator levels. The access control system applies to the front panel HMI, embedded web browser based HMI, and the PCM600, Protection and Control IED Manager.
