Description

Current transformer drainage wire appurtenance

Technical Field

The invention relates to an auxiliary tool, in particular to an auxiliary tool for a current transformer drainage wire.

Background

Most current transformers that use in present transformer substation all install the position more than 3 meters apart from ground, and the mutual-inductor connecting plate can reach 6 meters high apart from the position on ground, and the wire length between current transformer and switch all is more than 4 meters for the mutual-inductor connecting plate has born very big horizontal pulling force. Make the work of taking off and connecing the current transformer connecting wire very hard, use the rope to tie up during present way and carry on the drainage line, draw down through bypassing mutual-inductor top pressure relief valve with the rope, hold by 3 to 4 people, then remove by one person and tear the head open. The pressure relief valve is simple and rough to operate, is easy to jam due to stress of the pressure relief valve, cannot correctly act when a fault occurs, causes equipment damage and damages to operators.
