REF545KB133AAAA ABB 饋線保護裝置或饋線保護測控裝置

REF545KB133AAAA 是一款饋線保護裝置或饋線保護測控裝置，由ABB公司制造。饋線保護裝置是電力系統(tǒng)中的重要設(shè)備，主要用于在饋線（即輸電線路）發(fā)生短路、接地故障或其他異常情況時，快速切除故障部分，從而保護電力系統(tǒng)的穩(wěn)定運行。

這款裝置能夠感應(yīng)電力系統(tǒng)中的異常電流、電壓信號，并與事先設(shè)定的故障保護條件進行比較。一旦檢測到故障，它會迅速切斷故障環(huán)節(jié)，防止故障向整個電網(wǎng)擴散。這有助于減少故障對電力系統(tǒng)的影響，保障電力供應(yīng)的連續(xù)性和穩(wěn)定性。

REF545KB133AAAA 的工作原理基于安裝在饋線上的電流、電壓傳感器。這些傳感器能夠檢測、測量和處理故障信號，從而進行故障的判斷和快速切除。該裝置采用數(shù)字信號處理技術(shù)，能夠快速、準確地檢測饋線故障，并實現(xiàn)快速切除，進一步確保電力系統(tǒng)的安全和穩(wěn)定運行。

總的來說，REF545KB133AAAA 是電力系統(tǒng)中的重要組成部分，對于提高電力系統(tǒng)的可靠性、穩(wěn)定性和安全性具有重要意義。通過快速、準確地檢測和切除饋線故障，它有助于減少停電時間、降低設(shè)備損壞風險，并保障電力供應(yīng)的連續(xù)性。

The REF545KB133AAAA is a feeder protection device or feeder protection measurement and control device manufactured by ABB. The feeder protection device is an important device in the power system, which is mainly used to quickly remove the fault part when the feeder (that is, the transmission line) has short circuit, ground fault or other abnormal conditions, so as to protect the stable operation of the power system.

The device can sense abnormal current and voltage signals in the power system and compare them with pre-set fail-safe conditions. Once a fault is detected, it quickly cuts off the fault link and prevents the fault from spreading throughout the grid. This helps to reduce the impact of faults on the power system and ensure the continuity and stability of the power supply.

The REF545KB133AAAA works on the basis of current and voltage sensors mounted on the feeder. These sensors can detect, measure and process fault signals for fault judgment and rapid removal. The device adopts digital signal processing technology, which can detect feeder fault quickly and accurately, and realize fast cutting, and further ensure the safe and stable operation of power system.

In general, REF545KB133AAAA is an important part of the power system, which is of great significance to improve the reliability, stability and safety of the power system. By quickly and accurately detecting and removing feeder faults, it helps reduce outage times, reduce the risk of equipment damage, and ensure continuity of power supply.
