為什么(me)要采用電氣火災監控系統

   電氣(qi)火(huo)(huo)災(zai)(zai)監控(kong)系(xi)統(tong)與傳統(tong)火(huo)(huo)災(zai)(zai)自動(dong)報(bao)(bao)警(jing)系(xi)統(tong)不(bu)(bu)同的(de)是(shi)，電氣(qi)火(huo)(huo)災(zai)(zai)監控(kong)系(xi)統(tong)早期報(bao)(bao)警(jing)是(shi)為(wei)了(le)避免損失，而傳統(tong)火(huo)(huo)災(zai)(zai)自動(dong)報(bao)(bao)警(jing)系(xi)統(tong)是(shi)為(wei)了(le)減少(shao)損失。所以，這就是(shi)說(shuo)為(wei)什(shen)么不(bu)(bu)管是(shi)新建或(huo)是(shi)改建工(gong)程項目，尤其是(shi)已經安(an)裝(zhuang)了(le)火(huo)(huo)災(zai)(zai)自動(dong)報(bao)(bao)警(jing)系(xi)統(tong)的(de)單位(wei)，仍需要安(an)裝(zhuang)電氣(qi)火(huo)(huo)災(zai)(zai)監控(kong)系(xi)統(tong)的(de)根本原因。

  其基本原理是，當電(dian)(dian)(dian)氣(qi)設備中的(de)電(dian)(dian)(dian)流、溫度(du)(du)(du)等參數發生異常或突(tu)變(bian)(bian)時，終端(duan)探(tan)測頭(如剩余電(dian)(dian)(dian)流互感(gan)器、溫度(du)(du)(du)傳感(gan)器等)利(li)用電(dian)(dian)(dian)磁場(chang)感(gan)應原理、溫度(du)(du)(du)效應的(de)變(bian)(bian)化對該信息進行采集，并(bing)輸送(song)到監(jian)控探(tan)測器里.

電氣火(huo)(huo)災監控(kong)(kong)系(xi)統經(jing)放大、A/D轉(zhuan)換、CPU對變(bian)化的(de)幅值(zhi)進(jin)行分析、判斷，并(bing)與(yu)報(bao)警(jing)(jing)(jing)(jing)設定(ding)值(zhi)進(jin)行比(bi)較，一旦超出(chu)設定(ding)值(zhi)則發出(chu)報(bao)警(jing)(jing)(jing)(jing)信號，同時也輸送到監控(kong)(kong)設備中(zhong)，再經(jing)監控(kong)(kong)設備進(jin)一步識別、判定(ding)，當(dang)確(que)認(ren)可(ke)能(neng)會(hui)發生火(huo)(huo)災時，監控(kong)(kong)主機發出(chu)火(huo)(huo)災報(bao)警(jing)(jing)(jing)(jing)信號，點亮報(bao)警(jing)(jing)(jing)(jing)指示(shi)燈，發出(chu)報(bao)警(jing)(jing)(jing)(jing)音(yin)響，同時在液晶顯(xian)示(shi)屏上(shang)顯(xian)示(shi)火(huo)(huo)災報(bao)警(jing)(jing)(jing)(jing)等信息。
