带负荷更换跌落式熔断器专用引流工具的研制

Development of Special Drainage Tool for Replacing Drop Fuse with Load

传统带负荷更换跌落式熔断器采用软质绝缘引流线短接跌落式熔断器上、下端头进行作业,此作业方式存在较多问题。为此,开展带负荷更换跌落式熔断器专用引流工具的研究,研制一种适用多场合的用于带负荷更换跌落式熔断器的硬质引流工具,其具有携带方便、操作简单、安全性和可靠性高的特点,避免了传统软质绝缘引流线重心不稳、易晃动、存在短路风险等问题。有效地提高了带负荷更换跌落式熔断器作业的效率与安全性。

The traditional drop fuse with load replacement is usually operated by the upper and lower ends of the short drop fuse with soft insulated lead,which has many problems.This paper studies the special drainage tool for replacing drop fuse with load,and develops a hard drainage tool for replacing drop fuse with load,which is convenient to carry,simple to operate,safe and reliable.It avoids the problems of unstable gravity center,easy shaking and short-circuit risk of traditional soft insulated drain wires.It effectively improves the efficiency and safety of replacing drop fuse with load.
