Abstract

The utility model of the insulated hanging wire rope traction type foreign matter remover for electric power overhead transmission lines is characterized in that it includes a fixing clip, and an insulating hanging wire rope is fixedly connected to the center of the fixing clip, and is located in the four corners of the fixing clip. Any two corner positions are fixedly connected with foreign matter removal knives. When in use, the heavy object is thrown over the overhead transmission line above the operation point by using the insulating hanging wire rope to fasten the heavy object. The ground operator operates the insulating hanging wire rope to move along the transmission line. The removal of suspended objects on and below the transmission line can enable the operator to use the ground potential live work without the power transmission line being powered off, and can realize the removal of suspended foreign objects on the power overhead transmission line without the need for equipotential on-line live work. It has the advantages of reasonable structure, easy operation, safe use, high working efficiency, good effect of removing foreign matter, and saving operating personnel.

Description

Insulated hanging wire rope traction type foreign matter remover for overhead power transmission lines

technical field

The utility model relates to a device for removing hanging objects in overhead electric power transmission lines, which is an insulated hanger rope traction type foreign matter remover for overhead electric power transmission lines.

Background technique

In recent years, hanging objects such as kite strings, plastic sheets, and canvases have posed serious hazards to overhead power transmission lines. They can easily cause single-phase grounding of transmission lines, short-circuits between phases, and other faults, resulting in the failure of normal operation of the line. For example, on the evening of February 25, 2009, citizens flying kites with metal wires in the Tiantan area of Beijing caused power equipment failures, causing power outages in some areas such as the Temple of Heaven.

At present, two methods of operation are mainly adopted for the removal of hanging objects on overhead power transmission lines: one is equal potential live operation processing; the other is after power failure, maintenance personnel go out to handle. The above two operating methods in the prior art require more manpower and material resources, and there are disadvantages such as complicated operating procedures, long operating hours, heavy physical exertion of operators, and poor safety and reliability.

Contents of the invention

The purpose of this utility model is to provide a method that can remove foreign objects hanging on the overhead power transmission line without the need for equipotential on-line live work by operators using ground potential live work when the power transmission line is not powered off, and the structure is reasonable. Easy to operate, safe to use, high operating efficiency, good effect of removing foreign matter, and saving workers' power. .

The purpose of this utility model is achieved by the following technical solutions: an insulating hanging wire rope traction type foreign matter remover for overhead power transmission lines, which is characterized in that it includes a fixing clip, and an insulating hanging wire is fixedly connected to the center of the fixing clip. A wire rope is fixedly connected with a foreign body removal knife at any two corners of the four corners of the fixing clip.

The foreign matter removal knife is a sickle head.

The insulating hanger rope traction type foreign matter remover for electric power overhead transmission lines of the utility model has an insulating hanger rope fixedly connected to the center of the fixing clip, and is fixedly connected to any two corners of the four corners of the fixing clip. The foreign matter removal knife, when in use, is thrown over the overhead transmission line above the operation point by using the insulating hanging wire rope to fasten the heavy object, and the ground operator operates the insulating hanging wire rope to move along the transmission line, and is fixed on the upper corner of the fixing clip. The foreign object removal knife removes the suspended objects from above the transmission line; the foreign object removal knife fixed at the lower corner of the fixing clip removes the suspended objects from the bottom of the transmission line, so that the operator can use the ground potential live work when the transmission line is not powered off. It can realize the removal of suspended foreign matter on the overhead power transmission line without equipotential on-line live work. It has the advantages of reasonable structure, easy operation, safe use, high operating efficiency, good effect of removing foreign matter, and saving operators.

FIG. 2 is a schematic left view of FIG. 1 .

In the picture: 1 foreign body removal knife, 2 fixing clips, 3 insulating hanging wire ropes.

Detailed ways

Utilize accompanying drawing and embodiment to further illustrate the utility model below.

Referring to Fig. 1 and Fig. 2, the foreign object remover of the utility model with insulating hanging wire rope traction for overhead power transmission lines has a fixing clip 2, and an insulating hanging wire rope 3 is fixedly connected to the center of the fixing clip 2, and is located at the fixing clip 2. Any two corners of the four corners are fixedly connected with foreign matter removal knife 1. The foreign matter removal knife 1 is a sickle head.

When using the insulated hanging wire rope traction type foreign matter remover for overhead power transmission lines of the utility model, the insulating hanging wire rope 3 is used to throw heavy objects over the overhead transmission line above the operating point, and the ground operators operate the insulation The hanging wire rope 3 moves along the power transmission line, and the foreign matter removal knife 1 fixed on the upper corner of the fixing clip 2 removes the hanging objects from above the power transmission line; Removal, in the case that the transmission line is not powered off, the operator uses the ground potential live work, and does not need to be on-line live work at the same potential, and can realize the removal of foreign objects hanging on the power overhead transmission line.
