附录4:测试经验

 

测试前先用万用表或者摇表测试相相、相铠、相地之间的阻值(测试时把线路头悬空)判断出哪条相线是故障线是什么性质的故障,再选择对应的测试方法

 

1.断线短路的测试(断线的验证方法:把线路的一端短接在另一端用万用表测试,通则没断,不通则断线;万用表短路档有蜂鸣声即为短路)(1).先断开测试线对与设备的连接,使待测线路不带电,把黑色测试线插到测试口红黄夹子一个接断线相一个接同一电缆中另任一相线,相铠短路时红黄夹子一个夹断线相一个接外铠,先用自动测试。如无法解决改用手动测试分析(建议尽量选用手动测试)。手动分析测试:(1).先断开测试线对与设备的连接,使待测线路不带电。使用本仪器,先用智能测试,如无法解决改用手动测试分析(建议尽量选用手动测试)。手动分析测试:按调整键, 直至范围 XXX米反白显示,按“◄”键或“►”键选择合适的范围;再按脉冲键,仪器显示测试的波形。按调整键,直到幅度  XX 反白显示。 这时,按“◄”键或“►”键即可调整幅度(幅度从1到99可调),以波形尽量大但不要跑出屏幕去为原则;按一下脉冲键随后按“◄”键或“►”键移动光标到故障波形的左边拐点处,左下角显示的数据就是故障点的米数。从线路的两端分别测试,把两端测试的数值带入:线路总长为L;A端测试结果m1;B端测试结果m2;则从A端的精确距离={m1/(m1+m2)}*L这样得出的数值也比较精确,线路有并接线的尽量把并接线拆除,不然会影响测试结果 (2).对于单根线拼凑起来的情况不能用长度测试断线长度。采用探测办法:信号发生器的红色夹子夹在有断线故障的一根相线上,黑色夹子接地钎(不可使用接地网),电缆其他相线要保持接地即可。信号发生器选择正弦波带着测试仪拿探头顺着电缆探测,断线故障点后面基本听不到信号器的声音,从而定位故障点的位置。(听不到声音时电缆埋多深后退多少)。

 

2对于相间绝缘不好电缆(相间漏电,相间阻值不大于200KΩ),在长度测试方法上通过比较的办法测试:首先测试故障线对,按“调整”键,直到范围 反白显示,这是调整到合适的范围(以涵盖线路长度的最小范围为宜),此时按“调整”键,直到记忆 反白显示,这时,按“◄”键或“►”键即可将当前波形记忆,并且液晶最后一行会提示“已记忆当前波形”。 然后不要改变任何参数,把测试夹更换到同一电缆中一对好线按一下“脉冲”键,此时按“调整”键,直到比较 反白显示,这时,按“◄”键或“►”键,两个波形将同时显示,两个波形出现明显差异的地方一般就是故障点(故障点的位置波形不同)。通过◄和►键把光标移动到波形不同点,屏幕上显示米数即为故障点的距离,从而确定故障点的位置。

 

3关于波速度的校准方法:取和测试电缆相同材质,长度在50---100米电缆;调节到合适范围,按脉冲键观察屏幕波形,并适当调节幅度,使屏幕波形易于观察,移动光标到反射波的拐点处,屏幕下方显示故障距离,通过增大、减少键调节波速度使得下面距离数和实际相等时,这时的波速度就是测试电缆的波速度。正常铜线—172;铝线—234。若不想校准波速度还能有精确距离:线路总长为L;A端测试结果m1;B端测试结果m2;则从A端的精确距离={m1/(m1+m2)}*L。

 

4.电缆路径查找:护层-大地接法是对带铠装电缆(不带电电缆)进行路径探测的最佳接线方式,将电缆近端的护层接地线解开,低压电缆的零线和地线的接地也应解开,对端的电缆外铠保持接地,信号发生器的红色夹子夹护层(外铠)黑色夹子接地钎接大地(不可使用接地网),电缆相线保持悬空,信号发生器选择信号正弦波测试仪配探头通过耳机信号以及液晶显示信号强度变化找到电缆走向。不带铠电缆路径查找时信号发生器红夹子接相线黑夹子接大地,线路另一端要接地。

 

5.对地漏电故障的测试,先用万用表筛选出对地阻值最小的线(最低阻值在500K内),信号发生器红色夹子接在对地阻值最小的相线上,黑色夹子接地钎,带着测试仪耳机顺着线路探测,用音频甲、音频乙配合探杆时声音最大点即为故障点,正弦波配合探头时信号在故障点会有明显的衰减,总之声音的差异点为漏电故障点. (电缆本身的接地线要拆开)

 

6.相对凯漏电的测试,先用万用表筛选出对铠阻值最小的线(最低阻值在500K内),信号发生器红色夹子接在对铠阻值最小的相线上,黑色夹子接外铠,与对地漏电测试方法相同,

 

在探头探测的过程中,应尽量地开小音量,使耳机听到清晰信号为准,因为音量过大会使哑点范围变宽,辨别时不够明显。

 

电力地埋电缆故障情况比较复杂,故障往往伴随发生,针对不同的故障状态选择对应的测试方法,有时两种方法相互验证,更准确的找到故障点;故障越严重相对越好测试,所以测试中尽量选择故障状态严重的线测试。
