ABB REF615 馈线保护和控制继电器

ABB REF615 馈线保护和控制继电器

REF615可作为配电网中架空线和馈线的主保护，也可作为变压器等设备的后备保护。主要用于电力变电站、电厂等电力行业以及水泥、冶金、石化、汽车、半导体、造纸、烟草等工业用户，也可用于市政、机场、港口、房地产等行业。为满足用户需要，REF615可以提供7种标准配置的应用。保护逻辑和相关功能均针对中国市场需求进行了特别优化。

保护控制功能齐全 集成弧光保护REF615提供带方向或无方向过流和接地故障保护，同时也支持过压、低电压、零序电压保护、热过负荷保护、灵敏接地保护及速断接地保护（包括间歇性接地保护）。

此外，该装置还集成了灵活配置的多轮次重合闸功能，可实现重合闸前、后加速和手合加速功能。REF615加装可选配件，还可直接集成三个弧光保护通道。用户无需另外购置和安装弧光保护装置即可实现对开关柜断路器、电缆和母线室的弧光检测和快速保护。

REF615支持当地和远方控制功能。用户通过装置面板上的控制按钮或者后台监控系统（SCADA）即可实现对断路器的分、合闸操作。为防止未授权用户误操作并保证用户按照相应权限操作，该装置定义了四个级别的操作权限：浏览者、操作员、工程师和管理员。不同级别用户使用不同的账号和密码登陆。这些权限设置适用于各种访问方式，包括装置面板操作，web访问及使用PCM600装置配置工具。

The REF615 can be used as primary protection for overhead lines and feeders in the distribution network, as well as backup protection for equipment such as transformers. Mainly used in power substations, power plants and other power industry and cement, metallurgy, petrochemical, automobile, semiconductor, paper, tobacco and other industrial users, can also be used in municipal, airport, port, real estate and other industries. To meet user needs, the REF615 is available in seven standard configurations. The protection logic and related functions are optimized for the Chinese market.

Full protection control Integrated arc protection The REF615 provides directional or no-directional overcurrent and ground fault protection, as well as over voltage, low voltage, zero sequence voltage protection, thermal overload protection, sensitive ground protection, and quick-break ground protection (including intermittent ground protection).

In addition, the device also integrates the multi-turn reclosing function with flexible configuration, which can realize the pre-reclosing acceleration, post-reclosing acceleration and hand acceleration. The REF615 comes with optional accessories and directly integrates three arc protection channels. Users do not need to purchase and install arc protection devices to realize the arc detection and rapid protection of switchgear circuit breakers, cables and bus rooms.

The REF615 supports local and remote control. The user can operate the circuit breaker through the control button on the panel of the device or the background monitoring system (SCADA). In order to prevent unauthorized users from misoperating and ensure that users operate according to the appropriate permissions, the device defines four levels of operation permissions: viewer, operator, engineer and administrator. Different levels of users use different accounts and passwords to log in. These permissions are set for a variety of access methods, including device panel operations, web access, and using the PCM600 device Configuration tool.
