IICSC-306GZ數(shù)字式發(fā)電機(jī)轉(zhuǎn)子接地保護(hù)裝置 說(shuō)明書(shū)
第 1 篇 裝置的技術(shù)說(shuō)明
1 概述
1.1 適用范圍
CSC-306GZ數(shù)字式發(fā)電機(jī)轉(zhuǎn)子接地保護(hù)裝置是基于DSP和MCU合一的32位單片機(jī)開(kāi)
發(fā)的發(fā)電機(jī)轉(zhuǎn)子一點(diǎn)接地保護(hù)裝置,該裝置可適用于電廠綜合自動(dòng)化系統(tǒng)(可以直接與后臺(tái)
系統(tǒng)進(jìn)行通信),“乒乓式”原理和“注入式”原理可選(需訂貨時(shí)說(shuō)明)。
1.2 裝置主要特點(diǎn)
1) 改進(jìn)“乒乓式”原理的轉(zhuǎn)子一點(diǎn)接地保護(hù)
改進(jìn)的“乒乓式”原理、高精度雙 A/D 硬件冗余設(shè)計(jì),切換開(kāi)關(guān)采用最新的 MOSFET
電子器件并實(shí)時(shí)監(jiān)視其狀態(tài),保證了轉(zhuǎn)子接地電阻的高精度測(cè)量和保護(hù)的可靠性。該保護(hù)能
自動(dòng)跟蹤勵(lì)磁電壓,靈敏度高且與接地點(diǎn)位置無(wú)關(guān)。即使在軸電刷接觸不好的情況下,保護(hù)
也不會(huì)誤動(dòng)。
