蓄電池故障定位儀

一、產品簡介
   蓄電池故障尋蹤（定位）儀是一款經濟型手動調節(jié)的儀器，可以在線對接地故障進行鑒別、尋蹤和定位。能夠抗強電磁場的干擾。故障尋蹤可以快速確定故障位置，避免反復試驗不能確定故障位置，而需要停電檢測。正是具有這樣的優(yōu)點，才得到廣泛的應用。

二、產品應用
   蓄電池接地故障尋蹤儀由便攜式在線信號發(fā)生器和接收裝置組成，能確定接地故障的數(shù)量和嚴重程度。儀器由故障點阻抗和系統(tǒng)電容組成一個橋式測量電路。信號發(fā)生器能夠用來確定接地故障的數(shù)量和嚴重程度。在直流電流和交流脈沖達到15A時，能排除因電磁干擾而產生的錯誤讀數(shù)，在使用手提式接收器和夾鉗式傳感器尋蹤時，接收器屏幕顯示信號的幅值，采用多路開關調節(jié)靈敏度，已達到顯示效果。

三、測量原理
   蓄電池故障尋蹤（定位）儀發(fā)射一個交流信號到帶電或不帶電回路中，信號在電纜故障點的阻抗上產生一個反極性波，通過測量這個波的幅值，可以確定故障點的位置。在故障點阻抗小于100 kΩ時使用單個夾鉗式傳感器，能夠靈敏的在接收器上顯示信號強度，而準確的定位。

四、產品特點

Battery Ground Fault Tracer
Battery Test Equipment

• Ground faults in ungrounded dc battery systems easily located
• Operates in high electrical noise environment
• Simplifies fault tracing by identifying fault characteristic (resistive and capacitive) magnitudes

The Battery Ground-Fault Tracer is an economical, manually-balanced instrument that identifies, tracks and locates ground faults in ungrounded dc battery systems - on-line. It is particularly effective in a high electrical noise environments, as the strength of the test current can be adjusted.

The Battery Ground-Fault Tracer accelerates fault location by eliminating trial-and-error procedures and because faults can be located without going off-line. It is particularly useful in any industry where supply of power for operating measurement, communication and control equipment is critical.
