A monofilament winder for repairing transmission line conductors and its application method

Abstract

The invention relates to a single-filament winder used for repairing wire of a power transmission line and a use method of the single-filament winder, and belongs to the technical field of power transmission lines. The winder comprises a handle, a base plate and a cover plate. One end of the base plate is connected with the handle and the other end is equipped with a U-shaped groove opening. A fixed shaft, three groups of rubber roller shaft, a spring sheet shaft and a positioning shaft are arranged around the U-shaped groove opening. Three groups of spring sheets are fixed on the spring sheet shaft. Three groups of rubber rollers are fixed on the rubber roller shaft. The fixed shaft, the spring sheet shaft and the positioning shaft are fixed by the cover plate through bolts. A wire disc shaft is arranged on the base plate. A wire disc is installed on the wire disc shaft and is fixed by a force resisting bolt. A repair point of the wire is clamped by the three rubber rollers, and after a single-filament aluminum wire is threaded in the wire disc through the positioning shaft, the winder is rotated to move forward in a rotary manner, so the repair point of the wire is repaired. The whole technique is free of gaps and kept flat, so a good use effect is achieved.

Description

technical field [0001] The invention relates to a monofilament winding device, in particular to a monofilament winding device used for repairing transmission line conductors and a method for using the same, belonging to the technical field of transmission lines. Background technique [0002] Transmission lines transport electric energy from power plants or substations to load centers. Along the way, they need to cross mountains and mountains, cross rivers and rivers, and have to withstand severe cold and heat, as well as wind, frost, rain and snow. Severe environmental conditions have a great impact on the electrical and mechanical properties of transmission line conductors and lightning conductors, and strand breaks often occur in conductors and lightning conductors. At present, personnel are used to climb ladders for manual repair operations. However, during the repair process, often due to process or material reasons, the binding is not tight and the gap is too large. The...

Problems solved by technology

At present, personnel are used to climb ladders for manual repair operations. However, during the repair process, often due to process or material reasons, the binding is not tight and the gap is too large. The high-voltage line will produce corona phenomenon during operation, resulting in Secondary heating, in severe cases, will cause severe strand breakage, until the wire is burnt and the line trips

[0003] If it is withdrawn and restarted, it will affect the tightness of the previous turns. If it starts from the beginning, then the whole repaired aluminum wire will be folded back and forth, and its mechanical strength will be greatly reduced. It cannot be restored to its original shape or it will be broken due to metal fatigue. It not only causes material waste, but also increases maintenance time, increases labor intensity, seriously affects power transmission time, and reduces power supply reliability
