摘要：多年以来，电力电缆运行与维护部门对电力电缆刺扎，均按照行业标准DL409-91第234条要求，采用人工试扎待锯电缆，一旦电缆识别出错，误刺扎带电运行电缆将造成极大的危害。本文在电缆刺扎器的基础上，研制一套辅助安全装置，集电缆识别与刺扎于一体。具体实现技术为：首先采集电缆识别仪信号，将其作为控制刺扎器的一个控制信号，只有在电缆识别无误的情况下，刺扎器的遥控器才有效，进而工作人员按下遥控器的控制按钮才可启动刺扎器进行工作;否则遥控器的电源电路处于断开状态，遥控器失效。电缆识别仪的信号通过无线发送模块发送给刺扎器的遥控器，工作人员只需要远程操作刺扎器即可。该装置操作简单、安全稳定，避免了由于工作人员失误造成的误刺扎，为电力人员的人生安全提供了保障。

Abstract： For years， the power cable for power cable operation and maintenance department stung， all in accordance with article 234 of the industry standard DL409-91 requirement， try using artificial saw cable， once the cable error identification， error stung charged run cable will cause great harm cable stung device is presented in this paper， on the basis of developing a set of auxiliary safety device， integrating cable identification and stung The specific implementation technology is as follows： firstly， the signal of the cable recognition instrument is collected and used as a control signal to control the puncture device. Only when the cable is correctly identified can the remote control of the puncture device be effective， and then the staff can start the puncture device to work by pressing the control button of the remote control. Or disconnect the power circuit of the remote control， remote control cable identification device failure signal by wireless transmission module is sent to the sting of a remote control device， staff need to remote operating stung device only can the device is simple and safe and stable operation， to avoid the stung by mistake due to staff errors， has provided the safeguard for electricity personnel life safety.

引言

目前，电力电缆运行与维护部门对待锯电缆刺扎，大部分采用无线遥控液压电缆刺扎器，这种刺扎方式避免了人工试扎造成的人身安全。但是一旦电缆识别出错，误刺扎带电运行电缆仍会对设备造成极大的危害，引起高压短路，进而相关区域停电，造成国民经济受损。为了防止对非故障电缆进行穿刺接地，保证正常电缆的安全可靠，提出在原刺扎器的基础上加装一套辅助安全装置，在故障电缆首端通过电缆识别仪施加信号，电缆识别仪的接收端接收信号，同时将接收的信号通过无线通信方式发送给刺扎器上的遥控器，只有当遥控器接收到信号后，刺扎器方可工作，否则整个回路失效。……
