Abstract
The utility model discloses a power cable core enameling mold comprising a hollow shell and a converted alloy body which is provided in the ends of the shell, a plurality of paint filling hole are also provided in the shell of the enameling mold and connected with the inner shell, thereby, the core can be uninterrupted moving through the mold hole, the paint filling can be lasted, the core is painted by the employing shower form, the enameling is homogeneous and the thickness of the paint layer are rudimental uniformed, the cable insulation effect can be assured, meanwhile, a position groove is provided on the shell for mold positioning and fixing.
Description
[technical field]
The utility model relates to power cable, relates in particular to the mould that the core of power cable is wrapped lacquer.
[background technology]
Power cable is the cable that transmits or distribute high-power electric energy to use in electric power system.The electric energy that is sent by the power station connects the power transformation power distribution station of various voltage levels by overhead transmission line, power cable, then delivers to each and uses electric unit.Power cable is compared with other aerial bare line, and its advantage is to be subjected to extraneous weather to disturb little, safe and reliable, hidden, less maintenance, durable in use, can lay under various occasions.
Power cable mainly contains the oil-impregnated paper insulation power cable with a lead sheath, the rubber insulation power cable, and polyvinyl chloride insulation, pvc sheath power cable, self-tolerant oil charging cables etc. are multiple.Its operating voltage is higher, thereby requires cable to have good electrical insulation properties.Power cable, all will wrap varnished insulation to core and handle after melting, calendering, wire drawing, twisted wire are processed into core from raw material, and the cable of rubber insulation and polyethylene insulation is finished insulated wire cores by extruder and curing tube; Paper insulated cable is held core, vacuumize, immersion oil with insulating paper finish insulated wire cores.
At present, it all is core to be crossed by paint bath earlier enter bag lacquer mould again behind the lacquer and carry out homogenizing that power cable is wrapped varnished insulation, enamelled coating when this mode is crossed lacquer on the core is inhomogeneous, some local enamelled coating is thicker, and some local enamelled coating is thinner, during by bag lacquer mould, though can make enamelled coating obtain certain homogenizing, but effect is not very desirable, and the distribution of final enamelled coating is not very even, has influenced the insulation effect of cable.
[summary of the invention]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of power cable core bag lacquer mould, and enamelled coating is wrapped on the core equably, guarantees the insulation effect of cable.
For achieving the above object, the utility model proposes a kind of power cable core bag lacquer mould, comprise the shell and the cemented carbide body of hollow, be provided with cemented carbide body in the two ends of described shell, also comprise some notes lacquers hole, does not put on shell in described notes lacquer hole, communicates with the inside of shell.
As preferably, the quantity in described notes lacquer hole is 3.
As preferably, also comprise first location notch, described first location notch is arranged on the shell near the rearward end position.
As preferably, described shell integral body is hexagonal cylinder shape.
As preferably, also comprise second location notch, on a face of hexagonal cylinder, have second location notch.
As preferably, be rectangular shape in the middle of described second location notch, two ends are semicircle.
The beneficial effects of the utility model: the utility model is provided with some notes lacquers hole on shell body, core passes nib and constantly moves, and annotates and constantly annotates lacquer in the lacquer hole, adopt the mode of shower to coat with lacquer to the core bag, bag lacquer evenly, enamelled coating thickness basically identical has guaranteed the insulation effect of cable.Simultaneously on shell body, have location notch, make things convenient for the positioning and fixing of mould.
Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
[description of drawings]
Fig. 1 is the schematic diagram of the utility model power cable core bag lacquer mould;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is that the B of Fig. 1 is to view.
[embodiment]
Fig. 1 is the schematic diagram of the utility model power cable core bag lacquer mould; Fig. 2 is the A-A cutaway view of Fig. 1; Comprise the shell 2 and the cemented carbide body 1 of hollow, be provided with cemented carbide body 1 in the two ends of described shell 2, also comprise some notes lacquers hole 3, described notes lacquer hole 3 is arranged on the shell 2, communicates with the inside of shell 2.Some notes lacquer hole 3 is set on the shell 2, and core passes nib and constantly moves, and annotates and constantly annotates lacquer in the lacquer hole 3, and the mode that adopts shower is to core bag lacquer, the bag lacquer evenly, enamelled coating thickness basically identical has guaranteed the insulation effect of cable.The quantity of annotating lacquer hole 3 preferably adopts 3, and annotating lacquer hole 3 is circular port, and lacquer, better effects if can be annotated to core in different positions in the hole of adopting 3 front and back to distribute.Comprise that also first location notch, 4, the first location notchs 4 are arranged on close rearward end position on the shell 2, conveniently are fixed to mold position on the anchor clamps.The described shell 2 whole hexagonal cylinder shape that adopt.
Fig. 3 is that the B of Fig. 1 is to view.On a face of hexagonal cylinder, have second location notch 5.In the middle of second location notch 5 is rectangular shape, and two ends are semicircle.The location hole of this structure is simple in structure, good positioning effect.
The foregoing description is to explanation of the present utility model, is not to qualification of the present utility model, any structure after the utility model simple transformation is all belonged to protection range of the present utility model.
