摘　　要：等电位作业最关键的技术措施就是如何安全稳妥地进入强电场,尤其是在500kV小塔窗或者狭基塔的情况下,这一点特别重要。文章就某次带电作业技能竞赛中进入等电位的几种方式进行点评,指出由于塔窗小,组合间隙不够,用硬梯从塔窗直接进入是一种危险的作业方式。进而强调,要重视DL409—1991第165条规定的转移电位问题。The key technique of equal potential operation is how in safety and security to enter a strong electric field, and it is especially important in the case where the voltage is so high upto 500 kV level but in a small tower window or on a narrow base tower. This paper gives comments on the enter ways adopted in a electrification-operation competition, pointing out that it is a dangerous way to enter a small tower window without enough weaving space simply with rigid ladders. Furthermore, it is emphasized one should pay attention to the diversion potential problem indicated in the article 165 of the DL 409-1991 standard.
