產(chǎn)品概述

名稱：REX521GHHPSH50G保護(hù)單元

類型：綜合保護(hù)裝置繼電器

設(shè)計(jì)用途：專門用于中壓網(wǎng)絡(luò)中的保護(hù)、控制、測(cè)量和監(jiān)控功能

二、主要應(yīng)用

典型應(yīng)用：輸入和輸出饋線保護(hù)、變電站保護(hù)，以及電力變壓器的后備保護(hù)和高壓電動(dòng)機(jī)的保護(hù)。

作用：在饋線發(fā)生短路、接地故障或其他異常情況時(shí)，快速切除故障，保護(hù)電力系統(tǒng)的穩(wěn)定運(yùn)行。

三、技術(shù)特點(diǎn)

多處理器環(huán)境：基于多處理器環(huán)境設(shè)計(jì)，具有強(qiáng)大的處理能力和速度，能夠應(yīng)對(duì)復(fù)雜和大量的數(shù)據(jù)處理需求。

激勵(lì)輸入方式：支持傳統(tǒng)的電流和電壓互感器的激勵(lì)輸入，同時(shí)也支持通過輸入電流和電壓傳感器進(jìn)行激勵(lì)輸入，增加了應(yīng)用的靈活性和廣泛性。

人機(jī)界面功能：配備豐富的人機(jī)界面功能，包括導(dǎo)航按鈕、清除/取消按鈕和進(jìn)入按鈕等，支持語言選擇、設(shè)置值受密碼保護(hù)、顯示背光、顯示對(duì)比度、顯示測(cè)試、主要值的選擇以及光隔離串行通信端口等功能。這使得用戶可以方便地進(jìn)行本地操作，并通過指示消息獲取設(shè)備的狀態(tài)信息。

軟件解決方案：采用現(xiàn)代軟件解決方案，提高了運(yùn)行效率和數(shù)據(jù)處理能力。

Product overview

Name: REX521GHHPSH50G protection unit

Type: Comprehensive protection device relay

Designed use: Specially used for protection, control, measurement and monitoring functions in medium voltage networks

Second, the main application

Typical applications: input and output feeder protection, substation protection, and backup protection of power transformers and protection of high-voltage motors.

Function: When the feeder has short circuit, ground fault or other abnormal conditions, the fault can be quickly removed to protect the stable operation of the power system.

3. Technical characteristics

Multi-processor environment: Based on the design of multi-processor environment, it has powerful processing power and speed, and can cope with complex and large data processing needs.

Excitation input mode: Support the traditional current and voltage transformer's excitation input, but also support the input current and voltage sensor for excitation input, increase the flexibility and universality of the application.

Man-machine interface functions: equipped with rich man-machine interface functions, including navigation buttons, clear/cancel buttons and enter buttons, etc., support language selection, setting values protected by password, display backlight, display contrast, display test, main value selection and optical isolation serial communication port functions. This makes it easy for the user to operate locally and get the status information of the device through the indication message.

Software solutions: The use of modern software solutions to improve operational efficiency and data processing capabilities.
