| 摘 要： | 随着中国特高压电网的建设,对于特高压变电站内电磁环境的评估已经引起了相关部门的重视。为了保障工作人员的健康与安全,国内变电站工作人员在工作期间都穿有屏蔽服,减弱这种危害。为了评估高压变电站现有屏蔽措施的效能,根据国家的相关规范与标准,对500 kV变电站的电磁环境和目前的屏蔽措施进行了测试,分析了目前屏蔽措施的屏蔽效果,结果表明,目前变电站内的屏蔽服对工频电场的屏蔽效果较好,在测试模型的头部和胸部的屏蔽效能分别为39.4 dB和12 dB,但是对工频磁场的屏蔽效能较差,在相同的位置的屏蔽效能分别为0.09 dB和0.15 dB。建议在将来的特高压变电站屏蔽设计中,应改进对工频磁场的屏蔽。 |
