蓄电池故障定位仪

一、产品简介
   蓄电池故障寻踪（定位）仪是一款经济型手动调节的仪器，可以在线对接地故障进行鉴别、寻踪和定位。能够抗强电磁场的干扰。故障寻踪可以快速确定故障位置，避免反复试验不能确定故障位置，而需要停电检测。正是具有这样的优点，才得到广泛的应用。

二、产品应用
   蓄电池接地故障寻踪仪由便携式在线信号发生器和接收装置组成，能确定接地故障的数量和严重程度。仪器由故障点阻抗和系统电容组成一个桥式测量电路。信号发生器能够用来确定接地故障的数量和严重程度。在直流电流和交流脉冲达到15A时，能排除因电磁干扰而产生的错误读数，在使用手提式接收器和夹钳式传感器寻踪时，接收器屏幕显示信号的幅值，采用多路开关调节灵敏度，已达到显示效果。

三、测量原理
   蓄电池故障寻踪（定位）仪发射一个交流信号到带电或不带电回路中，信号在电缆故障点的阻抗上产生一个反极性波，通过测量这个波的幅值，可以确定故障点的位置。在故障点阻抗小于100 kΩ时使用单个夹钳式传感器，能够灵敏的在接收器上显示信号强度，而准确的定位。

四、产品特点

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.
