Telescoping high voltage insulating rod

Abstract

The invention relates to the technical field of power equipment, and particularly relates to a telescoping high voltage insulating rod comprising an insulating bar, a stainless steel clip, DC motor batteries and fine wires. The insulating bar is composed of two insulating bars which are nested together. Every single internal insulating bar and the external insulating bar are composed of three insulating bars with a hollow structure, and diameter of the three insulating bars with the hollow structure decreases in turn. A fixed circular ring is connected at the internal side of the head part of one end of each segment of the external insulating bar. The head segment and the tail segment of the external insulating bar are respectively provided with a DC motor. The fine wires are wound on the shafts of the DC motors. The fine wires penetrate through the circular ring of the internal side of the external insulating bar and are wound a circle on the circular ring. The stainless steel clip is arranged at the tail end of the insulating bar. One piece of the clip is connected with the external insulating bar, and the other piece of the clip is connected with the internal insulating bar. Reliable connection can be realized, and artificial climbing and an elevating engineering vehicle can be omitted. The telescoping high voltage insulating rod has the characteristics of being simple in structure, easy and convenient to operate, variable in size and flexible and convenient to use so that personal safety and working efficiency of operators can be enhanced.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a telescopic high-voltage insulating rod. Background technique [0002] In the prior art, the transformer winding is the core part of the transformer. When the transformer is under the action of electrodynamic force and mechanical force, the size or shape of the winding is irreversibly deformed. The deformation of the transformer winding is one of the important reasons for the damage of the transformer. Short-circuit impedance method, low-voltage pulse method and frequency response method have been proposed at home and abroad to detect transformer winding deformation. Among them, the frequency response method is based on the equivalent circuit of the transformer, which can be regarded as a passive linear two-port network, and the frequency characteristics of the two-port network can be described by the transfer function. Since each transformer has its own correspondin...

AI Technical Summary

Problems solved by technology

[0008] Second, there are many parts, which is not easy to manage, and the parts are easy to lose

[0009] Third, for the frequency response method to measure the deformation of transformer windings, the device cannot reliably contact the end of the bushing

[0010] Fourth, the length of the insulating rod can only be adjusted by the number of insulating rod sections, and cannot be fine-tuned
