掃一掃!變壓器有載開關測試儀怎么選購,選擇變壓器有載開關測試儀的介紹掃一掃!

  介紹1:有載調壓變壓器在用電部門日益廣泛使用,因此對該變壓器上分接開關進行測試的有載分接開關測試儀器也日益增多。但市面上流通的儀器良莠不齊,以致對分接開關的測試效果也參差不一,許多廠家與用戶都希望對該測試儀能在有關檢測機構進行檢測,但許多檢測機構尚無配備此種檢測裝置,以致無法對該測試儀進行檢測。“變壓器有載開關測試儀校驗裝置”可對多種分接開關該測試儀進行檢測,效果良好,準確可靠。選購“變壓器有載開關測試儀校驗裝置”注意一下幾點:1、工作電源:AC 220V±10%50±1Hz。2、檢測范圍:過渡電阻1Ω,4.3Ω,10Ω,20Ω誤差:1%±0.1Ω過渡時間1ms-100ms,100-250ms誤差:1%±1ms。3、使用條件:(1)環境溫度:0-40℃(2)相對濕度:不大于80%。


  介紹2:“變壓器有載分接開關測試儀”作用:用于測量和分析電力系統中電力變壓器及特種變壓器有載分接開關電氣性能指標的綜合測量儀器??蓪崿F對有載分接開關的過渡時間、過渡波型、過渡電阻、三相同期性等參數的測量,目前市場上的變壓器有載分接開關測試儀主要有兩種:一種是單色屏,另一種是彩屏帶觸摸功能,我們以“GYYC變壓器有載分接開關測試儀”舉例說明,一個是老款,一個是新款,測試的參數都是一樣的,老款是單色屏,按鍵操作,新款是彩屏,觸摸操作,沒有按鍵,內置工控機,運算速度很快。帶U盤接口。彩屏儀器成本較高,所以要貴一些。
