750kv ground wire roller type wire coil

Abstract

The invention relates to a 750kV ground wire roller type wire coil. The 750kV ground wire roller type wire coil comprises a base, walking wheels are arranged under the base, a push handle is arranged at the rear end of the base, symmetrical bearing frames are arranged at the rear portion and the front portion of the base, bearings are arranged at the upper portions of the two bearing frames, a rotating shaft is arranged between the two bearings, and the rotating shaft is fixedly sleeved with a reel. Rotary discs and coiling discs are arranged on the reel from front to back at equal intervals, grounding fixing ends are arranged on the circumferential face of the reel, and conductor end supports are fixed to the base at the reel side. The 750kV ground wire roller type wire coil is simple in structure, ground wires can be reeled in three phases in a separated mode, and the conductor ends of the ground wires are independently arranged to be protected. The 750kV ground wire roller type wire coil can be arranged in a safe tool and instrument cabinet and is convenient to arrange and take. The 750kV ground wire roller type wire coil has a moving function, one person can convey the ground wires to a use place, the ground wires can be fast drawn out from the reel, and the three-phase ground wires are respectively unfolded into an available state. The ground wires are respectively wound to the reel after use, the ground wire winding phenomenon cannot appear.

Description

technical field [0001] The invention relates to a wire winding device, in particular to a 750kV grounding wire roller type reel. Background technique [0002] In the field of power system grounding technology, grounding wire is one of the most commonly used measures to ensure work safety in power outage maintenance operations. The safe distance of 750kV equipment without power failure is 7.2 meters, plus the distance of the frame, usually the 750kV grounding wire has a length of more than 10 meters, and because the grounding wire is made of copper wire and is divided into three phases, a pair of 750kV grounding wires weighs 50 Many kilograms, it is quite inconvenient to move. Currently, there are no suitable reels to carry 750kV ground wires. At present, there is no related product specifically for the 750kV grounding wire carrying device on the market. Therefore, the storage of the 750kV grounding wire has been placed in the suitcase at present. Because the grounding wir...

Problems solved by technology

The safe distance of 750kV equipment without power failure is 7.2 meters, plus the distance of the frame, usually the 750kV grounding wire has a length of more than 10 meters, and because the grounding wire is made of copper wire and is divided into three phases, a pair of 750kV grounding wires weighs 50 Many kilograms, it is quite inconvenient to move

The 750kV grounding wire is very long, and it is easy to cause the three-phase wires to be entangled with each other. It takes several staff members to spend a period of time to organize them into a usable state.

The operation time is delayed, and the physical strength of the staff is also great

After the 750kV grounding wire is used, when it is placed in the current use of the suitcase, it is likely to cause re-entanglement, which will cause inconvenience for the next use
