Q26UDVCPU可編程控制器

電力變壓器是靜止的電氣設備，工業企業的變壓器通常把6—10kv的高壓電降低為0.4kv的低壓電，供給電氣設備使用。一般把這種電力係統末一級，直接把電能供給用戶的變壓器稱為低壓配電變壓器。

　　一、低壓配電變壓器常見事故原因分析及應急措施

　　1．變壓器內部出現異常聲響。

　　變壓器內部出現異常聲響可能有以下原因：a．嚴重的過負荷使變壓器內部發生沉重的“嗡嗡”聲；b．由於內部有接觸不良或有擊穿點，使變壓器內部發生“吱吱”或“劈啪”的放電聲；c．由於變壓器頂蓋連接軸栓個別零件松動，變壓器鐵芯未被夾緊，造成硅鋼片振動，會發出強烈噪聲；d．電網中有接地或短路故障時，繞組中流過很大的電流，會發出強烈的噪聲；e．變壓器接有大型動力設備或能產生諧波電流的設備時，設備運行都可能導致變壓器發出“哇哇”的叫聲；f.由於鐵芯出現諧振，變壓器發生忽粗忽細的噪聲；g．變壓器的原邊電壓過高、電流過大都會發生異聲；h．由於過電壓、繞組或引出線對外殼放電，或鐵芯接地線斷開，致使鐵芯對外殼放電，均使變壓器發出放電聲。

　　應急措施：當發現變壓器發出異常聲響時，應根據上述分析判斷其可能的原因，有針對性的採取應急措施。如變壓器內部發出的異常聲響是由於零件松動或繞組導線擊穿產生的，應立即停電處理，以免事故進一步擴大。

　　2．變壓器油位過高或過低。

　　一般情況下油溫的變化可以改變油位。隨著油溫的變化，油位也相應出現—定範圍的改變。但是，在不正常情況下，由於滲油、滲水等故障和其他事故也會引起油位的異常變化。其次，油溫的變化與負荷狀況、環境溫度等條件有關。當油位變化與這些因素不一致時，則可能是假油位。出現假油位的原因：a．油標管堵塞；b．防爆管排氣孔堵塞。另外，油位過高將造成溢油；油位過低，則可能造成變壓器內部引出線乃至線圈外露，導致內部放電。

　　處理方法和應急措施：有氣體繼電保護的將其跳閘回路解除，防止誤跳閘。當班電氣設備操作人員要經常檢查油位計指示，發現油位過高時可適量放油；油位過低時及時補油。若是由於變壓器漏油引起的，則應採取停電檢修及其它應急措施。當發現油枕或防爆管異常噴油時，應立即切斷變壓器的電源，以防止故障和事故的擴大。

　　3．變壓器油質變壞或油溫突然升高。

　　在工作狀態時，變壓器油的主要作用是冷卻和絕緣。當長時間過熱運行或殼體進水，吸收潮氣，會使油質變壞。通過油標觀察會發現油色異常加深或變黑；經取樣分析可以檢驗出油內含有碳粒和水份，酸值增高，閃點降低，絕緣強度降低等。這種情況很容易在繞組與外殼間發生擊穿放電，造成嚴重事故。當變壓器正常運行時，油溫如果突然升高經常是變壓器內部過熱的原因。鐵芯著火，繞組匝間短路，內部螺絲松動，冷卻裝置故障，變壓器嚴重過負荷都可能使油溫突然升高。
