摘要
针对传统的电缆路径探测方法存在接线复杂、外界干扰大、不能满足目前工作需要等问题,阐述了电磁感应新方法的探测原理、运行电缆的信号发射和运行电缆路径探测(信号接收)方法,提出了该探测新方法在实际操作中的注意事项。分析结果表明,该探测新方法适用于电磁干扰强、环境较复杂的情况或电缆敷设密集的区域,能大幅度减少探测的盲目性,提高工作效率,减轻工作人员的劳动强度。
Since the＇traditional detection method for cable route is complicated for wiring, vulnerable to external en- vironment and hard to meet the requirement of work, this paper introducesthe theory of detecting by electromagnet- ic induction, signal transmission of cable in operation and detecting method for cable route, and proposes matters to mention of new detecting method in practical operation. Analysis result shows that this method applies to circum- stances such as strong electromagnetic interference and complicated environment and regions with concentrated ca- ble laying, reduces substantially blindness in detecting., enhances work efficiency and decreases the amount of hu- man labor.
