Product Overview
產(chǎn)品概述

The ABB REF545KB133AAAA is a high-performance power system protection device, specifically designed for medium-voltage power grids, capable of providing rapid, selective protection, monitoring and control functions.
ABB REF545KB133AAAA 是一款高性能的 電力系統(tǒng)保護(hù)裝置，專為中壓電網(wǎng)設(shè)計(jì)，能夠提供快速、選擇性的保護(hù)、監(jiān)控和控制功能。

It is applicable to a variety of power equipment, such as transformers, motors, capacitor banks, etc.
它適用于多種電力設(shè)備，如變壓器、電動(dòng)機(jī)、電容器組等。

This device adopts digital signal processing technology, which can quickly detect abnormal current and voltage signals in the power system and compare them with the preset fault protection conditions. Once a fault is detected, it immediately cuts off the fault connection to prevent the fault from spreading to the power grid.
該設(shè)備采用數(shù)字信號(hào)處理技術(shù)，能夠快速檢測(cè)電力系統(tǒng)中的異常電流和電壓信號(hào)，并與預(yù)設(shè)的故障保護(hù)條件進(jìn)行比較，一旦檢測(cè)到故障，立即切斷故障鏈接，防止故障蔓延至電網(wǎng)。
