Journal: Guangxi Electric Power

Keyword:  10 kV架空线路停电作业单相接地安全防护措施;
Abstract: 为了保护10 kV架空线路停电作业时人员的安全,对停电作业安全防护措施进行了探讨.首先对10 kV架空线路停电检修过程中突然单相带电时通过人体的电流进行分析,然后用阻值约为2 200Ω的电阻模拟作业人员人体电阻,对4种接地工况下线路停电过程突然单相带电时通过模拟作业人员人体的电流进行了测量.通过分析、试验,针对10 kV架空线路停电作业现有安全措施的不足,提出了作业人员在地面作业或在杆塔、金属斗车上作业时相应的安全防护措施.所提出的安全防护措施可大大减少通过作业人员人体的电流,有效确保作业人员安全.
