一种可用于带电更换水平双分裂导线多联板双联绝缘子串的卡具

The Development of Horizontal Double Split Conductor Double Strings Insulators Holder for Live Working

多联板双联组合绝缘子串应用越来越普遍,但目前尚缺乏专门用于带电更换多联板双联绝缘子串的卡具,导致作业效率低下。本文对多联板双联绝缘子串的组装方式和作业方式进行了分析,发现多联板荷载转移不恰当是效率低下的主因。据此,设计了一种多联板双联绝缘子串更换卡具,并对卡具曲梁强度进行了校核,验证了其安全性、可靠性。利用研制的卡具进行带电更换多联板双联绝缘子串,耗时仅需25min,作业效率提高48%。

The horizontal double split conductor double strings insulators are more and more commonly used, but the double strings insulators holder is still very lack, which leads to low operating efficiency. In this paper, assembly method and operation way of double strings insulators is analyzed, the inappropriateload transfer method is the primary cause of inefficient. Based on this, horizontal double split conductor double strings insulators holder for live working is designed. Its security and reliability is verifiedby checking the fixture curved beam intensity. Using the double strings insulators holder, replacing the insulator just takes only 25 minutes, and the efficiency increased by 48%.
