35、守，严禁测试期间电缆头及被测电缆本体或附近处有作业现象；2、切断被测物（电缆）电源，防止再次通电，确定被测物（电缆）上已无电压，隔离附近带电设施；3、升压实验时应在电缆头和实验设备四周装设网状围栏，悬挂“高压，危险！”标示牌，实验现场四周应派专人监护，禁止与实验无关人员靠近；3、升压时控制台操作人员应站在绝缘垫上，防止高压反击危及人员安全；4、加压过程中应注意观察电压是否波动、数据是否异常，并呼唱报时，发现有异常情况立即降压，直到查明原因后再重新开始加压；5、实验时无工作负责人许可，实验人员不得离开岗位或进行其他工作。6、工作负责人职责：1）检查实验设备是否正常；2）工作负责人作为专职监护人，

36、不参加工作班的实验工作；3）监督完成整个实验，现场实验由工作负责人统一指挥，包括实验顺序及人员分工。文档编码:CD2B8F4J3C6 HX5K3M8H1Z5 ZV9C3T9Y2Z4文档编码:CD2B8F4J3C6 HX5K3M8H1Z5 ZV9C3T9Y2Z4文档编码:CD2B8F4J3C6 HX5K3M8H1Z5 ZV9C3T9Y2Z4文档编码:CD2B8F4J3C6 HX5K3M8H1Z5 ZV9C3T9Y2Z4文档编码:CD2B8F4J3C6 HX5K3M8H1Z5 ZV9C3T9Y2Z4文档编码:CD2B8F4J3C6 HX5K3M8H1Z5 ZV9C3T9Y2Z4文档编码:CD2B8
