电力电缆线路检修危险点分析与防护探讨

Analysis and Discussion upon Protecting Danger Points in Maintaining Power Cable Lines

我们在电力电缆线路检修工作中,保证作业人员安全的技术和措施,依据我国《电业安全工作规程》的要求,一直都是做在被检修电缆的两端终端头位置。而在我们检修人员需要保护的检修位置(工作点)却看不到安全措施。由于受电力电缆线路隐蔽性的制约,和在检修工作中对两端安全技术和措施(接地线)监控的缺失,我们检修人员的生命安全就存在着一个致命的安全漏洞——安全防范的主动权没有掌握在自己的手中。由此而引发的一连串的安全事故隐患,正在"直接的"和"潜在的"威胁着我们的电缆线路检修作业人员,正成为我们作业人员的最大杀手。电力生产"安全第一,预防为主"是我们工作的第一要务。本文就目前我国电力电缆线路运行和检修的现状,以及在工作中存在的安全技术问题,结合工作中所发生的案例进行了剖析。并在电力电缆检修安全的两个重要环节"事前预防,事中控制"的手段上制定了一套切实可行的防控办法。

According to the requirements stated in Code of Safety Operation in Power Engineering, during the maintenance of power cable lines, technical measures to protect maintainers shall be generally taken upon the terminals of two ends of cables.However, there are almost no any safety measures at the maintenance places （operating points） for the maintainers.Due to the restriction of invisibility of power cable lines and the lack of monitoring in safety and technical measures （earthing lines） on two ends of cables in the maintenance,the maintainers have to face a fatal safety leak ——failure to positively perform safety protection.Therefore ,a series of hidden dangers are directly and potentially threatening the safety of the maintainers who are engaged in maintaining power cable lines, which will be the most serious killer for the maintainers.＂Safety First,and Protection First＂is the first task for all of us in power production.Based on the current maintenance in domestic power cable lines and existing technical difficulties,the article performs analysis through actual cases and establishes a set of applicable protective methods for the two key links＂Prevention in Advance, and Control in Progress＂relating to the safety of maintaining power cable lines.
