Abstract

The invention provides a threaded type high-voltage ground lead operation rod lengthening device. The threaded type high-voltage ground lead operation rod lengthening device is characterized by comprising a shell, the upper end of the shell is provided with a protective ring clamp, an outer cylinder is in threaded connection with the interior of the shell, an inner cylinder is rotationally arranged in the outer cylinder, and a limiting device is arranged between the outer cylinder and the inner cylinder; and a first opening is formed in the side face of the outer cylinder, a second opening is formed in the side face of the inner cylinder, and a control rod is connected to the inner cylinder. By the adoption of the technical scheme, a worker can hang a ground lead on a high circuit or device standing on the ground; and meanwhile, the device is safe, reliable and convenient to carry, time and labor are saved, and working efficiency is improved.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a threaded high-voltage grounding wire operating rod extension device. Background technique [0002] In the construction of high-voltage lines or substation maintenance, portable high-voltage grounding wires are commonly used to prevent electrostatic induction electric shocks near electrified bodies or to ensure safety when closing the switch by mistake. However, when the grounding wire is suspended on a line or equipment with a high height, due to the limited length of the operating rod, it is necessary to use an insulating step stool to increase the height, thereby reducing the safe distance between the human body and the live equipment, and there is also a risk of falling from the step stool. Dangerous, there are potential safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned defect...
