摘要:
为确保±800 kV特高压直流输电线路带电作业的安全可靠进行,结合实际作业需要,提出了一种适用于特高压直流输电线路的等电位进出方式,通过建立三维有限元模型,计算典型工作位置的人体体表电场强度,分析作业路径的安全性;并采用电磁分析软件对电位转移电流进行分析。结果表明,作业过程中,作业人员体表最大电场强度为1 706 kV/m,在进入等电位过程中,采用电位转移棒能够有效降低电位转移时加在人体的冲击电流幅值,降幅高达86.7%,保护了人体及屏蔽装置的安全。
Abstract:
To ensure the safety of live working on ±800kV DC line, based on the technical requirements, putting forward the application which is used to UHVDC living work. At the same time, by using the three dimensional finite element model to prove the safe of the workers. The results show that the field worker's maximum surface electric field strength is 1706 kV/m in the process of the worker enter; And when the worker uses the potential rod enter the potential, the impact current amplitude can effectively reduce up to 86.7%. So it can protect the safety of the worker and the shielding device.
