几种停电电缆鉴别方法的比较

电缆鉴别方法是一种用于现场在不同停电电缆中鉴别所需电缆的方法,不同场合采用不同的鉴别方法。人工挖掘鉴别法适用于现场电缆线路单一的情况;工频感应鉴别法在并列运行的电缆较多时很难完成鉴别;音频信号鉴别法依赖于现场鉴别人员的工作经验;脉冲电流鉴别法能够十分准确地鉴别电缆,但有时无法使用接收夹钳接收信号。人工挖掘鉴别法和工频感应法均有其局限性,而音频信号鉴别法和脉冲电流鉴别法可以大范围适用。实践证实了,只有将音频信号鉴别法与脉冲电流鉴别法结合使用,才能提高电缆鉴别的准确率。

Comparison of Power Cable Identification Method

Cable identification method is used for identify the required cable in different cables at working field, different working field needs different method to identify the cable. Artificial mining identification method could used in the working field where the situation is fairly simple; power frequency induction method is difficult to complete the identification in the cables which are running at the same time; the audio frequency signal identification method depends on the personnel work experience; pulse current identification method can accurately identify the cable, but sometimes cannot use the clamp to receive signals. Artificial mining identification method and power frequency induction method has its limitations, but the audio frequency signal identification method and pulse current identification method can be widely available. Practice has proved that, only the audio frequency signal identification method and pulse current identification method used in combination, can improve the correct rate of cable identification work.
