1 電氣火災(zāi)的防控形勢
隨著科學(xué)技術(shù)的發(fā)展、人類社會的進(jìn)步和我國城市化進(jìn)程的不斷加快,電能的生產(chǎn)和使用量逐年遞增,已成為zui主要的能源。隨著人們對安全用電常識了解的逐漸深入,由于不規(guī)范用電引發(fā)的人身傷害事故逐年遞減,而由電氣故障引發(fā)的火災(zāi)數(shù)卻在增加,重特大火災(zāi)和群死群傷的惡性火災(zāi)事故時有發(fā)生,這與我國火災(zāi)總數(shù)呈逐年遞減的趨勢形成了鮮明的對比。據(jù)部門統(tǒng)計,2008~2012年全國*門共統(tǒng)計67.5萬起火災(zāi),在查明原因的約62.3萬起火災(zāi)中,電氣火災(zāi)約20.8萬起,占33.37%。如2010年吉林市商業(yè)大廈、2011年長沙市西娜灣賓館、2011年北京市大興區(qū)舊宮鎮(zhèn)出租房、2012年天津市薊縣萊德商廈等電氣火災(zāi)的發(fā)生給人民群眾生命財產(chǎn)安全帶來了嚴(yán)重威脅。面對如此嚴(yán)峻的電氣火災(zāi)形勢,如何盡早排除火災(zāi)隱患,zui大限度地避免和減少電氣火災(zāi)的發(fā)生,已成為消防行業(yè)火災(zāi)預(yù)防工作的重點(diǎn)、難點(diǎn)和社會關(guān)注的焦點(diǎn)問題。
2 電氣火災(zāi)發(fā)生的原因分析
電氣火災(zāi)主要由于電氣線路或設(shè)備短路、過電流、接觸不良、漏電等電氣故障引發(fā)。引發(fā)電氣火災(zāi)的電氣故障從其表現(xiàn)形式上看分為:突變型故障和漸變型故障。突變型故障也稱為金屬性短路故障;過電流、接觸不良、漏電等電氣故障一般先是表現(xiàn)為漸變型故障,漸變型故障未得到及時消除,zui終將演變?yōu)橥蛔冃凸收稀u變型故障發(fā)生后,將以不可逆的態(tài)勢向突變型故障發(fā)展,在這個過程中直接表現(xiàn)為電能的非正常釋放,即泄漏電流的增大、接線端子等處溫度的升高以及故障電弧的產(chǎn)生,這些因素zui終均會導(dǎo)致故障點(diǎn)溫度的升高,尤其是故障電弧產(chǎn)生的上千℃的高溫足可以引燃周圍的可燃物,從而引發(fā)火災(zāi)。---淺談電氣漏電火災(zāi)監(jiān)控系統(tǒng)和電氣火災(zāi)預(yù)防措施
3 電氣火災(zāi)監(jiān)控系統(tǒng)
電氣火災(zāi)監(jiān)控系統(tǒng)是指當(dāng)被保護(hù)線路中的被探測參數(shù)超過報警設(shè)定值時,能發(fā)出報警信號、控制信號并能指示報警部位的系統(tǒng)。電氣火災(zāi)監(jiān)控系統(tǒng)是一種電氣火災(zāi)預(yù)防的手段,是作用于電氣火災(zāi)發(fā)生前的一種實(shí)時監(jiān)控系統(tǒng),與作用于火災(zāi)發(fā)生后的“火災(zāi)自動報警系統(tǒng)”在承擔(dān)任務(wù)、功能和采取的技術(shù)手段等方面均是不同的,兩者不能混淆和取代。
“ARCM”電氣火災(zāi)監(jiān)控系統(tǒng)是由安科瑞電氣股份有限公司自主研發(fā)和生產(chǎn)的,包括Acrel-6000電氣火災(zāi)監(jiān)控系統(tǒng)軟件及ARCM系列電氣火災(zāi)監(jiān)控探測器組成。它是一種應(yīng)用于民用建筑和工業(yè)建筑雙重領(lǐng)域的新一代電氣火災(zāi)監(jiān)控產(chǎn)品,具有超早期、高智能、小型化、多功能、高可靠性、簡單實(shí)用等特點(diǎn)。該裝置是結(jié)合多年來該公司在國內(nèi)外工業(yè)領(lǐng)域及民用建筑領(lǐng)域得系統(tǒng)集成項目中所積累下的大量寶貴經(jīng)驗(yàn)研制而成的。該監(jiān)控設(shè)備采用工業(yè)計算機(jī)進(jìn)行設(shè)計研制,具有良好的可靠性,同時優(yōu)化了人機(jī)交互功能,使整個系統(tǒng)易于安裝、調(diào)試及維護(hù),主機(jī)采用總線制數(shù)據(jù)傳輸方式,配接剩余電流式電氣火災(zāi)監(jiān)控探測器,組成大容量電氣火災(zāi)監(jiān)控系統(tǒng),適用于高層建筑和各種工業(yè)場所的早期電氣火災(zāi)實(shí)時監(jiān)控及預(yù)防。
