    【摘 要】 金屬氧化物避雷器存在發熱缺陷會對電氣設備安全運行造成嚴重影響,針對實際中遇到的一起110kv避雷器發熱案例進行了試驗和解體,分析了產生故障的原因和預防措施,為今后更好的開展避雷器故障檢測和處理提供支撐。
      【關鍵詞】 氧化鋅避雷器 發熱 檢測 維護措施
      金屬氧化物避雷器moa是目前變電站限制雷電侵入波過電壓的主要設備,常用的無間隙氧化鋅避雷器其閥片具有著高涌流能力和很好的非線性特征,有效保護電氣設備避免因過電壓而造成絕緣擊穿。如果避雷器存在發熱等缺陷將失去保護作用,造成設備損壞甚至變電站停電等事故,因此運行中必須對避雷器工作狀態和性能進行檢測。在利用紅外線精確測溫技術對某變電站110kv ii母線避雷器進行測試時,發現b相避雷器呈現出發熱趨勢,對此本文進行了深入分析。
      1 避雷器熱缺陷基本情況
      110kv ii母線所采用的避雷器為yh10wz-100/200型無間隙氧化鋅避雷器,內部由氧化鋅閥片串聯疊裝而成直接承受電網運行電壓,正常情況下氧化鋅閥片具有較高的涌流能力和非線性特征,絕緣外套由硅橡膠和高強度環氧玻璃纖維套管制成。該避雷器戶外配置,常年經受雨雪、污穢及溫度變化的影響,運行環境較為惡劣,試驗人員8月27日在紅外精確測溫時發現b相避雷器中上部存在發熱,最高溫度達34.9℃,下部溫度29.6℃,單節溫差較大,并對3相避雷器進行了帶電測試:a相全電流0.607ma、阻性電流峰值0.094ma,b相全電流0.709ma、阻性電流峰值0.111ma,c相全電流0.613ma、阻性電流峰值0.097ma。www.zhidachem.com
      停電后將故障避雷器拆除并剝離復合外套,對整體氧化鋅閥片進行了直流試驗,剝除復合外套后0.75倍u1ma的泄漏電流值由原來的204ua下降到150ua,但是仍超出50ua的狀態檢修試驗規程標準。
      2 發熱缺陷原因分析
      2.1 解體查看
      將氧化鋅閥片外的環氧樹脂外包殼分節切割和拆除,并注意了內部結構的保護。解體后發現氧化鋅閥片外絕緣層皮存在鼓脹現象,可見抽真空時可能存在密封不嚴。剝開外絕緣皮,發現氧化鋅閥片從上至下的四分之三區域存在白色粉末物體,并且只是分布在一側,并沒有散布在整體外表面,由紅外圖譜與氧化鋅閥片可見光照片對比可以看出,發熱閥片范圍和白色粉狀物分布范圍存在一致的對應關系,均是自高壓端至下的三分之二,并且紅外圖譜顯示避雷器在某一側溫度是最高的36.4℃,其他側面溫度相對較低2~3℃。
      2.2 發熱原因分析
      造成金屬氧化物避雷器泄漏電流和阻性電流異常通常有以下幾個方面原因。
      (1)避雷器內部受潮。密封不良如運輸過程中橡膠絕緣外套受損出現了一些細微的裂紋、密封膠圈永久性壓縮變形等使潮氣侵入閥片;由于環境溫度冷熱交替,避雷器內空氣膨脹收縮的呼吸作用,使可能存在的微小漏孔逐步擴大,形成潮氣進入通道。當氧化鋅閥片受潮,運行中會造成泄漏電流增大,嚴重時可能出現沿閥片柱表面和絕緣套內壁表面的放電,甚至引起爆炸。
      (2)閥片本身老化引起故障。由于氧化鋅閥片直接接入電網電壓,長期在工頻或諧振過電壓作用下避雷器絕緣性能會不斷劣化,當泄漏電流流過閥片時其中有功分量將使閥片本身發熱,造成其伏安特性變化,長期發熱導致溫升的后果是加速老化,陷入惡循環,直至發生熱擊穿。
      (3)環境污穢影響引起的避雷器損壞。當環境污穢及在高溫環境下,極易造成避雷器電場分布不均,在避雷器上部靠近法蘭處電流很大更易引起老化。根據以往運檢記錄可知,避雷器故障大多發生在夏季高溫污穢地區。而且,當避雷器絕緣外套存在污穢在雨雪作用時,避雷器內外電位不同,使得閥片與絕緣外套間產生一個徑向電位差,可能造成局部放電。
      (4)避雷器發生熱擊穿。當避雷器發熱功率比散熱功率大時,熱量的積蓄可使閥片溫度升高甚至使絕緣外套熱擊穿。發熱功率由通過閥片電流的有功分量決定,因此監測總電流中有功部分可以知道發熱功率的變化;而散熱功率取決于環境溫度、周圍介質和避雷器結構尺寸等因素。
      該避雷器解剖后中上部氧化鋅閥片表面存在的白色粉末狀物質應是閥片進水受潮后發熱產生的遺留物,受潮造成避雷器絕緣水平下降,使泄漏電流增大;當內部不能保持足夠干燥時加速閥片老化,在中上部每節閥片的壓接處,發現有金屬銹蝕痕跡,而底部閥片節間仍保持光亮,說明避雷器中上部閥片發生

    一定程度氧化。
      3 處理和維護措施
      針對金屬氧化物避雷器存在的發熱缺陷原因,結合國內外近年來運行經驗,做好防范措施:
      (1)在選擇避雷器時,其氧化鋅閥片的設計、選材及裝配過程的密封、檢漏非常重要,特別是高阻層的致密性、耐潮性和絕緣性能關乎著運行過程中性能的穩定,把好導致避雷器熱缺陷的第一關。
      (2)日常運行中要加強定期巡視和紅外線精確測溫,特別是雷雨季節前后和易發生故障位置,及早發現可能存在的避雷器熱點,根據輸變電設備狀態檢修試驗規程做好相關測試工作,認真分析直流電流1ma時的參考電壓值u1ma、75%u1ma時的泄漏電流等指標的變化情況,如果條件允許最好進行交流電流1ma時的參考電壓等項目診斷性檢測。
      (3)要做好避雷器的防污措施,如定期進行清掃或涂抹防污閃rtv,避免因絕緣外套污穢而造成散熱不良和電場分布不均勻。
      (4)完善檢測記錄,對運行中的全部避雷器分別建立技術檔案,將交接試驗、定期測試報告、紅外精確測溫圖譜以及在線監測儀的運行記錄都要入檔,并與歷史數據進行比較做好分析工作,加強全壽命周期管理。
      4 結語
      氧化鋅避雷器發熱缺陷對設備和電網安全運行有著較大的影響,根據多年運行記錄和國內外相關資料,氧化鋅避雷器故障原因通常有受潮、閥片老化、污閃、雷電和諧振過電壓等,但還有部分情況原因不明,需要在今后的實際運行中加強檢測分析、不斷總結,降低避雷器發熱的故障率,一方面要嚴格執行技術標準做好測試工作,還要在運行中積極引入各種先進檢測手段,避免避雷器熱缺陷造成變電站停電甚至事故擴大的情況發生。
