Benefits of technology

This patented technology provides a special tool for measuring resistance between different parts of electrical conductors without damaging them during their manufacturment process. By placing both end portions of the conductor under pressure from another component called a stress-loading element, it becomes more reliable when compared against current methods like strain gauge measurement techniques used previously.

Problems solved by technology

In this patented technical problem addressed by the current testing method described in the previous reference describes how different types of materials (metal) may have their own unique properties when exposed to certain conditions or environments. These differences result in reduced reliable tests conducted over time due to changes caused by external factors such as lighting impacts or temperature fluctuations.

Abstract

The invention relates to an insulating pull rod characteristic testing device. The insulating pull rod characteristic testing device comprises a closed air chamber with an observation window, and further comprises a voltage loading piece and a grounding piece, wherein the voltage loading piece and the grounding piece are located in the closed air chamber or extend into the closed air chamber and are oppositely arranged at an interval so as to form a mounting fracture in the closed air chamber; and the voltage loading piece and the grounding piece are respectively provided with a connecting endused for being connected with a to-be-tested insulating pull rod located at the mounting fracture. The testing device further comprises a force loading mechanism which is in transmission connection with the grounding piece so as to apply tension to the to-be-tested insulating pull rod through the grounding piece. The to-be-tested insulating pull rod can simultaneously bear the superposition effect of the voltage load and the mechanical acting force, the voltage load and the mechanical acting force are mutually coupled and influenced, and the test environment of the to-be-tested insulating pull rod is consistent with the actual use environment of the to-be-tested insulating pull rod, so that the tested insulating performance of the to-be-tested insulating pull rod is closer to the actual situation, and the reliability is higher.
