Description

Technical Field

[0001] This utility model belongs to the technical field of electrical testing, specifically relating to an auxiliary connection tooling for detecting the resistance of a solid-sealed pole circuit. Background Technology

[0002] Solid-sealed poles are integral conductive poles formed by directly casting a vacuum interrupter along with other main circuit components into epoxy resin using advanced APG casting technology and special embedding technology. Vacuum interrupters are the core components of medium and high voltage power switches. Their main function is to use the excellent insulation of the vacuum inside the tube to quickly extinguish the arc and suppress the short-circuit current after the power is cut off, thus avoiding accidents and unexpected events.

[0003] In existing technology, the solid-sealed electrode contains a vacuum interrupter, and upper and lower leads connected to the two ends of the vacuum interrupter. The lower lead and the moving end of the vacuum interrupter are connected by an insulating pull rod and a flexible connection, and the upper lead and the moving end of the vacuum interrupter are connected by a screw fastening joint. However, these joints can cause an increase in circuit resistance due to loose connections. Therefore, the solid-sealed electrode must undergo circuit resistance testing at the factory to ensure that it is within the required range. However, the commonly used testing fixtures are usually complete sets of equipment with sensors to measure the pressure value, directly pressing the insulating pull rod, and then using a circuit resistance tester to test the circuit resistance of the solid-sealed electrode. For many manufacturers who have tensile and compressive testing machines, such complete sets of fixtures have some functional redundancy, high purchase costs, poor adaptability, and poor practicality.
