An integrated system for electrical inspection and grounding of cables based on the principle of internal expansion and resistance reduction

Abstract

The invention discloses a cable electricity testing and grounding integrated system based on the internal expansion resistance reduction principle. The structure comprises a locking mechanism, a mainsleeve member, a grounding pin, an internal expansion mechanism, a conical head, an electricity testing host and a control panel. The cable electricity testing and grounding integrated system is advantaged in that a wire is assembled through the locking mechanism, then, locking and fixing are performed through a tightening ring assembly in the locking device, an electric shock accident caused by wire falling is avoided, after the grounding pin is inserted into the ground, the electricity testing host confirms that wire grounding data is correct, when a piece needs to be taken, a piece taking pull handle is shifted, a direction control assembly drives the internal expansion mechanism to carry out internal expansion treatment on soil, so resistance is reduced, the grounding pin can be easilyand conveniently taken out at the moment, an external tool is not needed, damage to the device is avoided, and dragging damage to a wire in the taking-out process can be prevented.

Description

technical field [0001] The invention relates to the field of cables, in particular to an integrated system for electric inspection and grounding of cables based on the principle of internal expansion and resistance reduction. Background technique [0002] The traditional grounding device is directly connected and fixed with the grounding wire, and then the electrician directly carries out the maintenance work of the electrical equipment. However, due to the instability of the grounding wire, it is still impossible to be 100% sure whether it is connected after the electrical connection device is fixed, resulting in the maintenance process. Electric shock accidents have occurred, so major manufacturers have produced integrated electrical testing and grounding devices for the detection of grounding wires and the integrated use of grounding to improve safety. There are such problems in the use of existing technologies on the market: [0003] When the integrated device for elect...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an integrated system for electric inspection and grounding of cables based on the principle of internal expansion and resistance reduction, so as to solve the problem that the integrated device for electric inspection and grounding in the prior art needs to be picked up after use. The electric master shakes it and cooperates with tools to pry it. This process is difficult to control and will cause damage to the device. In addition, it is easy to drag the bottom of the wire during the shaking process, resulting in loosening and damage to the top of the wire. This problem needs to be improved.
