Problems solved by technology

However, when the existing operating rod is used for ground potential work, it is necessary to strip the insulated wires, which is cumbersome and difficult to construct.
In addition, due to the stripping work on the insulated wires, the outer insulation layer of the insulated wires is damaged, and it is prone to failure in weather conditions such as lightning strikes, which cannot effectively ensure the safety of power grids.

Abstract

The invention discloses a quick overlapping tool for a draining line applied to ground potential operation, which belongs to the technical field of power operation equipment, comprises a main clamping seat and a secondary clamping seat used for clamping an insulated wire and further comprises a sleeving rod. The main clamping seat is provided with a sliding groove, and the secondary clamping seat is arranged in the sliding groove movably. The front end of the sleeving rod is connected with the secondary clamping seat, and the sleeving rod drives the secondary clamping seat to moveably clamp the insulated wire with respect to the main clamping seat. The main clamping seat is provided with a clamping block used to have the drainage line clamped tightly. The main clamping seat and the second clamping seat have the insulated wire tightly clamped, and when the clamping block has the drainage line clamped tightly, the insulated wire and the drainage line are electrically communicated. The quick overlapping tool for draining line provided by the invention enables that the overlapping of a drainage line can be completed in the form of ground potential operation, which greatly reduces manpower and equipment needed for overlapping. The working time required for the overlapping is also shortened considerably. With the quick overlapping tool of the invention, the effective overlapping can be realized without stopping the power supply, so as to ensure the continuity and reliability of the power supply.

Description

technical field [0001] The invention relates to the technical field of electric power operation equipment, in particular to a quick bonding tool for drain wires used for ground potential work. Background technique [0002] With the development of society and economy, the requirements for power supply continuity and reliability of distribution network lines are getting higher and higher. When the single-circuit insulated line distribution transformer high-voltage leads are overheated, it is necessary to use the bypass operation method to realize the line protection. Drainage, so there are more and more live working occasions using operating rod bypass operations. However, when the existing operating rod is used for ground potential work, it is necessary to strip the insulated wires, the process is cumbersome, and the construction is difficult. In addition, due to the stripping work on the insulated wires, the outer insulation layer of the insulated wires is damaged, and it i...
