描述

產(chǎn)品細節(jié)說明：RED521 1MRK002003-BA ABB 通用差動保護端子

  1. 差動保護功能：
    • RED521 1MRK002003-BA通過比較進入和離開受保護區(qū)域的電流差異來檢測故障，實現(xiàn)快速響應(yīng)和故障隔離。這種差動保護機制對于防止電力系統(tǒng)中的短路、過載等故障具有重要意義。
  2. 適應(yīng)性強：
    • 該產(chǎn)品容易適應(yīng)不同的變電站配置，具備廣泛的自我監(jiān)督功能，確保在各種工況下都能穩(wěn)定工作。
  3. 實時性與準確性：
    • 實時時鐘與外部同步，確保時間戳的準確性。差動保護與操作時間通常只需10-15毫秒，提高了保護的實時性和準確性。
  4. 低CT要求：
    • RED521 1MRK002003-BA對CT（電流互感器）的要求較低，只需2毫秒飽和即可正確操作，降低了對CT性能的要求。
  5. 多種測量區(qū)與CT輸入：
    • 一個三相端子帶有一個測量區(qū)，為一個單一區(qū)域提供多達六個隔板的母線保護。三個單相端子帶有兩個測量區(qū)，為多達18個CT輸入提供相分離的母線保護。
  6. 監(jiān)控與通信：
    • 提供事件列表功能，最多可記錄16個事件，并顯示每個階段和保護區(qū)的模擬服務(wù)值。支持串行數(shù)據(jù)通信，便于與上層系統(tǒng)進行數(shù)據(jù)交換和監(jiān)控。
  7. 用戶界面友好：
    • 內(nèi)置本地人機界面與LED指示，方便用戶進行狀態(tài)查看和操作

Product Details: RED521 1MRK002003-BA ABB Universal Differential Protection Terminal
Differential protection function:
RED521 1MRK002003-BA detects faults by comparing the difference in current entering and leaving the protected area, achieving rapid response and fault isolation. This differential protection mechanism is of great significance in preventing faults such as short circuits and overloads in the power system.
Strong adaptability:
This product is easy to adapt to different substation configurations and has a wide range of self-monitoring functions to ensure stable operation under various working conditions.
Real time and accuracy:
Real time clock is synchronized with external devices to ensure the accuracy of timestamps. Differential protection and operation time usually only take 10-15 milliseconds, which improves the real-time and accuracy of the protection.
Low CT requirements:
RED521 1MRK002003-BA has lower requirements for CT (current transformer), and can operate correctly with only 2 milliseconds of saturation, reducing the requirements for CT performance.
Multiple measurement areas and CT inputs:
A three-phase terminal with a measurement area provides busbar protection for up to six partitions in a single area. Three single-phase terminals with two measurement zones provide phase separated bus protection for up to 18 CT inputs.
Monitoring and Communication:
Provide an event list function that can record up to 16 events and display simulated service values for each stage and protected area. Supports serial data communication, facilitating data exchange and monitoring with upper level systems.
User friendly interface:
Built in local human-machine interface and LED indicator, convenient for users to view and operate status
Product details and parameters: RED521 1MRK002003-BA ABB universal differential protection terminal
Input/output: Supports the current input of 1A or 5A main current transformers connected through taps, with one or two analog input modules, 24 outputs for binary output modules (pre configured at the factory), and 16 inputs for binary input modules (pre configured at the factory).
Power supply: The power module covers 24V to 250V DC ± 20%.
Working environment: The working environment temperature is standard kHz
Installation method: On site installation, modular structure.

RED521 1MRK002003-BA ABB application areas:

RED521 1MRK002003-BA is a powerful and adaptable universal differential protection terminal widely used in the protection and control fields of power systems.
