Description
Technical Field
The utility model relates to a power equipment preparation appurtenance technical field especially relates to an auxiliary labor-saving tool for 110kV cable head preparation.
Background
Along with the rapid development of the power industry, the application of electrical equipment-combined electrical apparatus with smaller floor area is gradually popularized and popularized, meanwhile, in order to save space and consider the appearance of the city, part of overhead lines are gradually developed towards the underground, the number of cables corresponding to the overhead lines is continuously increased, the outgoing lines and incoming lines of a plurality of transformer substations at present are all cable lines, generally, cable faults occur at a cable terminal head with a high probability, the manufacturing process of the cable head is particularly critical to ensure the safe and stable operation of a power grid, after a corrugated aluminum sheath is cut in the manufacturing process of the cable head at present, in order to prevent the trough of the aluminum sheath and the main insulation of the cable, in the process of forming a horn mouth by the corrugated aluminum sheath, the traditional method is to clamp the fracture of the aluminum sheath through a vice, so that the main insulation of the cable is easily damaged, and the fracture is not smooth even when force is applied, this method is time consuming and labor intensive, and not only affects the work efficiency but also may cause damage to the main insulation.
Based on the used instrument falls behind at ripple aluminium sheath formation horn mouth in-process in the present cable head manufacture process, seriously influences work efficiency and cable head preparation, this reason awaits urgent research and development a specialized tool that can be reliable and fast, will reach the effect that handles into the horn mouth with the fracture and polish the sharp-end unevenness position after the aluminium sheath fracture expands plumbous completion simultaneously to solve the low problem of efficiency in the cable head manufacture process.
Disclosure of Invention
To prior art's not enough, on the basis that does not change cable head preparation frock, make full use of cable structure characteristic combines actual work, and a research and development section is small, weight is lighter, easily carry, flexible operation, steady, the atress is balanced and possess and handle into the horn mouth with the fracture and polish two kinds of functions in the most advanced unevenness position after ripple aluminum sheath (6) fracture expands plumbous, can reach labour saving and time saving's specialized tool simultaneously.
The utility model provides a supplementary laborsaving instrument for preparation of 110kV cable head, its structure formula structure as an organic whole, including wide portion (1), narrow portion (5), draw-in groove (2), power handle (3), file portion (4).
The included angle between the clamping groove (2) and the left side surface of the wide part (1) is 120-150 degrees. When the novel corrugated aluminum pipe is used, the left side face of the wide portion is tangent to the cambered surface outside the corrugated aluminum sheath (6), on one hand, an acting point is arranged, so that the operation is more labor-saving, on the other hand, the opening angle of the machined horn mouth (7) is consistent, and the horn mouth (7) is more standard and uniform.
The width of the wide part (1) is 15-18mm, and the width of the narrow part (5) is 2-3 mm; the length of the clamping groove (2) is 20-30mm, and the width is 2.5-4 mm; the thickness of the tool is 6-7mm, the total length is 230-260mm, the sum of the lengths of the force-applying handle (3) and the file part (4) is 150-170mm, and the length of the file part (4) is 70-90 mm.
The edges of the clamping grooves (2) are designed to be rounded. The bell mouth (7) of the manufactured cable head is smoother, and the generation of burrs is reduced.
All edges of the tool are of a rounded design.
The file part (4) is used for polishing the uneven part of the tip after fracture expansion lead of the corrugated aluminum sheath (6) is finished. The clamping groove (2) is used for clamping the edge of the corrugated aluminum sheath (6).
The utility model discloses a use method does:
the using method comprises the following steps: narrow portion (5) of instrument are arranged in the inside of ripple aluminium sheath (6), and the outside of ripple aluminium sheath (6) is arranged in wide portion (1), and draw-in groove (2) are rotatory when outwards exerting an effort with the edge that blocks ripple aluminium sheath (6), handle into horn mouth (7) with ripple aluminium sheath (6) fracture, then polish the most advanced unevenness position after ripple aluminium sheath (6) fracture bloated plumbous with file sword portion (4).
The beneficial effects of the utility model reside in that:
the utility model discloses according to the thickness of cable ripple aluminum sheath and with the distance of inboard shielding layer, the supplementary laborsaving instrument of design size assorted cable head preparation has solved in the cable head manufacturing process, and ripple aluminum sheath trough injures and the condition of main insulation to guarantee that ripple aluminum sheath department bears the electric field equilibrium.
And the uneven part of the tip of the corrugated aluminum sheath after the fracture of the corrugated aluminum sheath is expanded with lead in the cable head manufacturing process can be polished smoothly, so that the working efficiency of the cable head manufacturing process and the safety and reliability of the cable head are improved.
The tool is used, so that the working efficiency is improved, the working time is saved, and the damage to the main insulation of the cable is avoided.
