Description

A grounding device for electrical testing applied to high-altitude power distribution equipment

technical field

The utility model relates to an electric testing grounding device applied to high-altitude power distribution equipment.

Background technique

In the construction of power lines, in order to ensure the safety of construction, it is necessary to carry out electrical inspection and hang the grounding wire before construction. At present, the bucket arm truck is used for electrical inspection and installation of grounding wires for high-altitude power distribution equipment. Or the equipment is on the side of a flat road, the slope of the road must not exceed 5%, and the width of the road must be greater than 8 meters (to ensure smooth roads), which limits the work site. In case of erection of high and low pressure on the same pole or multiple times of erection on the same pole, the safety distance of using bucket trucks is not enough. There is also the manual pole climbing for electrical inspection and installation of grounding wires. Manual pole climbing has the risk of falling from a high altitude and the risk of electric shock, and climbing poles will delay a lot of time, which will shorten the construction time.

The outer circumference of the clamping sleeve is provided with external threads, and the inner wall of the clamping ring is provided with internal threads that match the external threads. The clamping The upper end of the sleeve is provided with a conical constriction on the upper part of the external thread, and the upper end of the clamping ring is provided with a conical constriction. Several axial narrow grooves are evenly distributed on the conical constriction to make the clamping sleeve and the clamping ring When tightening, the conical constriction bears against the outer peripheral side of the conical constriction and forces it to tighten to clamp the upper support rod.

Further, the opening of the hook is provided with a ∧-shaped bayonet, the ∧-shaped bayonet is connected to the upper end of the down-conductor, and the lower end of the down-conductor is connected to a grounding device or an electroscope.

Further, both the clamping ring and the outer circumference of the clamping sleeve are provided with anti-slip patterns.

Compared with the prior art, the utility model has the following beneficial effects: the electric testing and grounding equipment applied to high-altitude power distribution equipment has a simple structure and reasonable design, and the height of the equipment can be arbitrarily extended according to the height of the high-altitude power distribution equipment. It is convenient, easy to operate, short in operation time, flexible in assembly, and can be applied to various operating locations. At the same time, operators do not need to operate at heights, ensuring the safety of operators and avoiding the risks of falling from heights and electric shocks.
