850-EP5NNG5HNNANNGSPBCSENNBN GE 电馈线系统

型号：850-EP5NNG5HNNANNGSPBCSENNBN

制造商:GE多林

系列: 850馈线保护系统

产品描述

850-EP5NNG5HNNANNGSPBCSENNBN是GE多林8保护继电器系列的一部分。

馈线保护系统是用于监控、管理和保护多达五个配电馈线系统（或六个没有母线电压测量的馈线系统）的一种多馈线保护系统。

馈线保护系统的特点如下1：

可进行数据记录和系统监控。

可自动检索事件和波形。

可自动下载Multilin驱动程序。

可协助自动检索事件和波形。

继电保护的基本工作原理是当电力系统发生短路或其他不正常状态时，继电保护装置需要发出指令，去命令断路器隔离线路或某故障设备，从而保障电力系统的安全稳定运行。

继电保护装置的原理是测量电气量（电流、电压、功率、频率等）的变化，从而判断电力系统是否发生故障。当这些电气量发生变化时，继电保护装置会将这些变化与正常值进行比较，如果超出正常范围，则判断电力系统发生故障，并采取相应的措施（如发出警告信号或令断路器跳闸等）来保护电力系统。

850-EP5NNG5HNNANNGSPBCSENNBN包括冷负载拾取、自动转换方案和自动重合闸等控制功能。该装置具有先进的诊断功能、状态监测和预防性维护报告。850-P5NNGSHNNANNGSPBCSENNBN是一个5A系统，设计有5A三相电流输入和接地输入。它的额定功率为3-110VDC/250-110 VAC电源。

850-EP5NNG5HNNANNGSPBCSENNBN的前面板提供全彩色GCP(图形控制面板)，允许用户读取关键测量值。导航糖和LED状态指示灯位于GCP正下方。前置USB端口便于连接、该装置的后面板提供对本机教字I/O模拟V/O以及CT和VT翰入、光纤端口、申源以及电行和R45以太网模块的访问。

Series: 850 feeder protection system

Product description

The 850-EP5NNG5HNNANNGSPBCSENNBN is part of GE's Dollin 8 protective relay family.

A feeder protection system is a multi-feeder protection system for monitoring, managing and protecting up to five distribution feeder systems (or six feeder systems without bus voltage measurement).

The characteristics of the feeder protection system are as follows:

Data logging and system monitoring are possible.

Automatically retrieves events and waveforms.

Multilin drivers can be downloaded automatically.

Facilitates automatic retrieval of events and waveforms.

The basic working principle of relay protection is that when the power system occurs short circuit or other abnormal state, the relay protection device needs to issue instructions to command the circuit breaker to isolate the line or a faulty device, so as to ensure the safe and stable operation of the power system.

The principle of the relay protection device is to measure the change of the electrical volume (current, voltage, power, frequency, etc.), so as to determine whether the power system fails. When these electrical volume changes, the relay protection device will compare these changes with the normal value, if it exceeds the normal range, it will judge the failure of the power system and take corresponding measures (such as issuing a warning signal or making the circuit breaker trip, etc.) to protect the power system.

The 850-EP5NNG5HNNANNGSPBCSENNBN includes control functions such as cold load pickup, automatic transfer scheme and automatic reclosing. The unit features advanced diagnostic capabilities, condition monitoring and preventive maintenance reporting. The 850-P5NNGSHNNANNGSPBCSENNBN is a 5A system designed with 5A three-phase current input and ground input. It is rated for 3-110VDC/250-110 VAC power supply.

The front panel of the 850-EP5NNG5HNNANNGSPBCSENNBN offers a full-color GCP(Graphical Control Panel) that allows the user to read key measurements. Navigation sugar and LED status indicators are located directly below the GCP. The front USB port facilitates connection, and the rear panel of the unit provides access to the native word I/O analog V/O as well as CT and VT incoming, fiber optic ports, Shenyuan, and the cable Bank and R45 Ethernet modules.
