YX2670H(匝間)耐壓測試儀@YX2670H%

YX2670H(匝間)耐壓測試儀@YX2670H%

概   述：
  YX2670H(匝間)耐壓測試儀是根據GB9706.1-1995《醫用電氣設備 第一部分：安全通用要求全等國家標準要求而研制、生產。用于測試各種控制變壓器、電源變壓器繞組匝間電介質強度.
    YX2670H型(匝間)耐壓測試儀是考核變壓器縱絕緣電氣強度的重要手段。本儀器采用脈寬調制，變頻技術將50Hz正弦波電源頻率調制變頻為250Hz正弦波等頻率，利用磁場感應原理，通過壓,對變壓器繞組的縱絕緣即匝間、層間、段間絕緣以及對其他繞組之間絕緣進行電介質強度考核。
   匝間耐壓測試是給變壓器繞組原邊加上5倍以上電源額定電壓和5倍以上頻率的電源，變壓器的主磁通會使原邊和副邊同時感應出感應電動勢，且分別是其額定工作狀態下的5倍以上，應此，匝間耐壓測試可以同時對變壓器主、副繞組進行縱絕緣性能電氣強度考核。

技術參數：

適用于GB9706.1規定的醫用設備變壓器繞組間電介質強度測試。
