| 摘 要： | 在对特高压交直流线路带电作业人员在各典型作业位置的体表场强进行了测量的基础上,分析了特高压交直流输电线路带电作业人员的体表场强特征,归纳了体表场强的变化情况,发现特高压直流线路带电作业人员的体表场强值明显小于特高压交流线路,并对其原因及机理进行了分析。同时对研制的特高压交直流带电作业用屏蔽服防护特性进行了试验研究,结果表明在特高压交流线路等电位作业时,屏蔽服内交流场强为2～10 kV/m;在特高压直流线路等电位作业时,屏蔽服内的直流合成场强为0.7～2.3 kV/m,均符合国家标准"15 kV/m"的规定,满足带电作业的安全防护要求。最后根据带电作业人员体表场强及安全防护用具的研究结果,制定了安全防护措施。

| Abstract: | The distribution characteristic of the field strength on the live working operators' body surface was analyzed on the UHV AC and DC transmission lines,on the basis of the outcome of field strength spot measurements on the body surface which had carried out on each typical work site during the live working,and the change of field strength was concluded.Field strength on the workers' body surfaces on the UHV DC transmission line was smaller than that on the UHV AC transmission,and the reason was discussed.Mea... |
