Description
Technical Field
The invention relates to the technical field of power cable cutting, in particular to automatic cutting equipment for a high-voltage cable insulating layer.
Background
The high voltage cable is a kind of power cable, which is used for transmitting power between 1kv and 1000kv, and is widely used for power transmission and distribution.
The high-voltage cable can be roughly divided into two parts, wherein one part is an external structure and mainly comprises an outer sheath, an armor layer, an inner sheath and a shielding layer. The other part is an internal structure which mainly comprises an outer semi-conducting layer, a main insulating layer, an inner semi-conducting layer and a wire core. The external structure has relatively low requirement on the precision of cutting processing, while the internal structure has relatively high requirement on the processing precision of the internal structure for realizing the insulation and shielding effects due to the direct action of the electromagnetic field of the high-voltage cable.
The internal structure of the high-voltage cable can be divided into two types according to the voltage class, wherein the voltage class of 10kV and below is a strippable structure of the outer semi-conducting layer and the insulating layer, and the voltage class of 10kV and above is a non-strippable structure.
The cable is a bridge between the power supply equipment and the electric equipment and plays a role in transmitting electric energy. The application is wide, so that faults also frequently occur. Generally, problems which easily occur in the cable production process include insulation eccentricity, uneven insulation shielding thickness, impurities in insulation, protrusion of inner and outer shields, uneven cross-linking degree, damp of a cable, poor sealing of a cable metal sheath and the like, faults possibly occur in a completion test or shortly after operation under certain serious conditions, most of the faults exist in a cable system in a defect mode, and serious hidden dangers are caused to long-term safe operation of the cable.
The prior high-voltage cable joint is of a wrapping type, a die casting type, a molding type and the like, the field manufacturing workload is large, and the problems are easy to occur because air gaps and impurities are inevitably generated between insulating tape layers due to the limitation of field conditions and the manufacturing process. The common domestic adopted types are an assembly type and a prefabricated type.
Cable joints are divided into cable terminal joints and cable intermediate joints, and cable joint faults generally occur at cable insulation shielding fracture positions regardless of joint forms, because the cable joint faults are electric stress concentration positions, the reasons of the cable joint faults caused by manufacturing reasons comprise manufacturing defects of stress cone bodies, insulating filler problems, oil leakage of sealing rings and the like.
The cable grounding system comprises a cable grounding box, a cable grounding protection box (with a sheath protector), a cable cross interconnection box, a sheath protector and the like. The common easy problem is mainly because the box body is not sealed well and water is introduced to cause multipoint grounding, which causes excessive induced current of the metal sheath. In addition, the damage of the protective layer protector is easily caused by the unreasonable selection of the parameters of the protective layer protector or the instable zinc oxide crystal with poor quality.
Therefore, when cable faults are checked and maintained, the cable insulation layer needs to be cut, in the cable cutting process, a traditional manufacturing tool is generally adopted, labor intensity is high, the control of cutting precision has extremely high requirements on the technical level of constructors, and accurate control is often difficult to realize. Therefore, it is urgently needed to design a cable insulation layer cutting device which can reduce the labor intensity of workers and improve the automation level and the intelligent degree of tools.
