產品概述
接地裝置的電氣完整性是指接地裝置中應該接地各種電氣設備之間,接地裝置的各部分及與各設備之間的電氣連接性,即直流電阻值,也稱為電氣導通性。電力設備的接地引下線與地網的可靠、有效連接是設備安全運行的根本保障。接地引下線是電力設備與地網的連接部分,在電力設備的長時間運行過程中,連接處有可能因受潮等因素影響,出現節點銹蝕、甚至斷裂等現象,導致接地引下線與主接地網連接點電阻增大,從而不能滿足電力規程的要求,使設備在運行中存在不安全隱患,嚴重時會造成設備失地運行。接地裝置的地下接地極及其連接部分也可能出現銹蝕、甚至斷裂現象。因此,定期對接地裝置進行電氣完整性測試是很有必要的。
 
電力行業標準DL/T475-2006《接地裝置特性參數測量導則》規定電氣導通性應選用專門的儀器進行測量,儀器分辨率為1mΩ,準確度不低于1.0級。我公司依據此標準研制的KDDT-10A 接地導通測試儀是一種自動化程度很高的便攜式測試儀, 專門用于接地裝置的電氣完整性測試,其各項技術指標均達到或優于相關標準要求。儀器操作簡單方便、精度高、測試速度快,復測性好、讀數直觀,是符合規程要求的專用儀器,方便了試驗項目的開展,提高了工作效率。

REKE-10A 接地導通測試儀適用于適用于電力設備接地引下線與接地網(或相鄰設備)之間導通電阻值的測量,同樣適用于低阻值電阻的測量。

性能特點
1.電源技術:采用新電源技術,輸出10A電流,能長時間連續工作,克服了脈沖式電源瞬間電流的弊端,可以有效的擊穿觸頭氧化膜,得到良好的測試結果。
2.抗干擾能力強:在嚴重干擾條件下,液晶屏最后一位數據能穩定在±1個字范圍內,讀數穩定,重復性好。
3.使用壽命長:全部采用高精度電阻,有效的消除環境溫度對測量結果的影響,同時軍品接插件的使用增強了抗振性能。
4.操作簡單:只需按下測量鍵即可得到測量結果。測量結果采用LCD液晶背光顯示,讀數直觀,重復性好。
5.攜帶方便:采用便攜式設計,體積小、重量輕。面板與機箱成一體結構,具有很好的抗震性。
