Novel test and operation wire hanging rod

Abstract

The invention relates to a novel test and operation wire hanging rod and a manufacturing method thereof, and belongs to the technical field of insulating tools. One end of a conductive short rod is connected with one end of a multifunctional joint, and one end of a conductive long rod is connected with the other end of the multifunctional joint; one end of a corner joint is connected with a jointof a multifunctional joint rod; and one end of an insulating rod is connected with the other end of the corner joint, and the other end of the insulating rod is connected with one end of a handheld insulting rod. The wire hanging rod is characterized by simple structure, high practicality, convenient assembly and operation and capable of being assembled flexibly, and can be used to detect voltagetransformers in different heights and with similarly L shaped interfaces. Different joints are used for different interfaces, difficulty in wire hanging in corners is overcome, the voltage transformeris avoided from collision or hurting people in the wire hanging process, the onsite work efficiency is improved, and the wire hanging rod can be popularized and applied widely in the power industry.

Description

technical field [0001] The invention relates to the technical field of insulating tools, in particular to a novel test operation hanging rod, in particular to a novel voltage transformer test operating hanging rod and a manufacturing method thereof. Background technique [0002] At present, in the 500kV voltage transformer verification of the power system, the operating hanging rod is often used to hang the electrical test wiring to ensure the safety of people and equipment. When verifying voltage transformers with a voltage level of 500kV and above, since the high-voltage terminal of the standard voltage transformer used is located very high, and the position of the hanging wire is located at the opening of the voltage transformer voltage equalizing ring, its shape is ┓ ,Such as figure 1 as shown, figure 1 Is the existing voltage transformer standard. Usually the upper end of the voltage transformer is provided with a connection bar. When the on-site voltage transformer ...

AI Technical Summary

Problems solved by technology

When the ordinary straight-type hanging rod is used for wiring, due to its single hook structure, the operating hanging rod may be skewed and unbalanced, and it may bump on the insulating sleeve of the voltage transformer to damage the insulation. In severe cases, it may even fall to other charged intervals and cause a short circuit of the equipment. , or hurt the staff and test equipment, which has a certain potential danger
