REF620E_F 技术技术参数

REF620E_F为架空线路提供主要保护，电缆馈线和配电变电站的母线系统。可用于接地和未接地配电系统。它为单身人士提供支持断路器、1,5断路器和双断路器馈线配置。灵活的订单编码允许选择佳配置满足您的配送器应用需求。

REF620E_F是强大、简单的同类馈线保护继电器，完美提供时间和瞬时过电流、负序过电流、相位步进距离、相位不连续、断路器故障、热过载以及电压测量和保护。继电器还具有高阻抗故障（HIZ）和敏感接地故障（SEF）的特点接地和未接地配电系统的保护

此外，REF620E_F继电器包含一个灵活的三相多触发自动重合闸功能，用于在架空线路的临时故障中自动恢复馈线。增强了安全选项，继电器提供三通道用于初级设备监督的电弧故障检测系统。REF620还集成了控制功能便于通过继电器控制多达2个断路器前面板人机界面（HMI）或远程控制系统保护继电器免受未经授权的访问保持信息的完整性，继电器已经提供具有四级、基于角色的用户身份验证系统查看器、操作员、工程师和管理员级别。门禁系统适用于前面板HMI、基于嵌入式web浏览器的HMI和PCM600，保护和控制IED管理器


REF620E_ F provides main protection for overhead lines, cable feeders, and busbar systems for distribution substations. It can be used in grounded and ungrounded power distribution systems. It provides support circuit breaker, 1,5 circuit breaker, and dual circuit breaker feeder configurations for singles. Flexible order coding allows you to choose the best configuration to meet your shipping application needs.
REF620E_ F is a powerful and simple feeder protection relay of the same type, perfectly providing time and instantaneous overcurrent, negative sequence overcurrent, phase stepping distance, phase discontinuity, circuit breaker failure, thermal overload, and voltage measurement and protection. The relay also features high impedance faults (HIZ) and sensitive ground faults (SEF) for protection of grounded and ungrounded power distribution systems

In addition, REF620E_ The F relay includes a flexible three-phase multi trigger automatic reclosing function for automatically recovering the feeder in the event of a temporary fault on an overhead line. Enhanced safety options, the relay provides a three channel arc fault detection system for primary equipment supervision. The REF620 also integrates control functions to facilitate the control of up to two circuit breakers through a front panel human machine interface (HMI) or remote control system to protect relays from unauthorized access and maintain information integrity. The relays have been provided with four levels of role-based user authentication system viewer, operator, engineer, and administrator levels. The access control system is suitable for front panel HMI, embedded web browser based HMI, and PCM600 to protect and control the IED manager
