Abstract
The invention discloses a process for manufacturing a safe drainage thread. The process comprises the following steps: firstly, selecting a 25 mm<2> annealed copper wire, winding at least four layers of insulated belts on the surface of the annealed copper wire, and keeping one half cushion ply in winding; secondly, performing thermal shrinkage treatment on the outermost layer of the annealed copper wire wound with the insulated belts by using a 10KV cable heat-shrinkage tube; and finally, performing compression joint treatment on two ends of the annealed copper wire. The process for manufacturing the safe drainage thread can manufacture the drainage thread with light weight, good flexibility, suitability for operation and low economic cost, and provides the safe drainage thread for exchanging a sealed fuse under 10KV uninterrupted power supply.
Description
Technical field
The present invention relates to the 10kV power distribution network, relate in particular to the do not have a power failure manufacturing process of safe drainage thread of transposing closed fuse of a kind of 10kV of being used for.
Technical background
In recent years, along with economic development is rapid, the sustainable growth of power consumption, make that the supply of quality power is increasing to social influence.Yet in the 10kV power distribution network; Often have device fails and cause user's power failure; In 10kV distribution network failure statistics; The ratio of the shared annual fault of fuse generation defective fault has reached 80%, is the principal element that causes that equipment fault causes the user to have a power failure, and wherein because the aging fault that causes of fuse has accounted for 87% of sum.In order effectively to reduce the generation of fault, can safeguard fuse, but workflow is quite loaded down with trivial details, not only need several departments to cooperate jointly, and need have a power failure to the user and reach 4 hours and could accomplish whole work.
Can adopt the dr transposing closed fuse that do not have a power failure, this method can be saved manpower, and promptness is good, weak point consuming time; Coverage is little, and the place takies few, and adaptability is good, and cost is low; Therefore, need a kind of safe drainage thread, can use cable to make drainage thread; But this kind method exists weight too big, and pliability is not enough, can't the one man operation; And the shortcoming that Financial cost is high perhaps can adopt the high-pressure induct line to make drainage thread, but this method exists weight too big; Obstruction is carried and is operated, the shortcoming that Financial cost is too high, and therefore how producing a kind of drainage thread in light weight, that pliability good, Financial cost is low is problem demanding prompt solution of the present invention.
Summary of the invention
The objective of the invention is to overcome the defective of prior art; And a kind of manufacturing process of safe drainage thread is provided; The advantage that it has that weight is low weight, pliability is fine, be fit to operation, Financial cost is lower is for the 10kV transposing closed fuse that do not have a power failure provides a kind of safe drainage thread.
The technical scheme that realizes above-mentioned purpose is: a kind of manufacturing process of safe drainage thread, and wherein, it may further comprise the steps:
At first, get a 25mm
2Annealed copper wire, twine at least four layers of insulation band on its surface, when twining, keep 1/2 bed course;
Secondly, the outermost layer with the annealed copper wire that winds the insulation band carries out the pyrocondensation processing with 10KV cable heat-shrink tube;
At last, crimping being carried out at the two ends of annealed copper wire handles.
The manufacturing process of above-mentioned safe drainage thread, wherein, described insulation band is a 3M insulation band.
The manufacturing process of above-mentioned safe drainage thread is characterized in that, the length of described annealed copper wire is 3 meters.
The invention has the beneficial effects as follows: the manufacturing process of a kind of safe drainage thread of the present invention, can produce a kind of safe drainage thread, make to continue 1 minute, no flashover or puncture by the minimum power-frequency voltage 45kv that reaches of drainage thread top layer insulation that produces.
Embodiment
To be described further the present invention below.
The manufacturing process of a kind of safe drainage thread of the present invention, it may further comprise the steps:
At first, get a 25mm
2Annealed copper wire, twine at least four layers of insulation band on its surface, when twining, keep 1/2 bed course;
Secondly, the outermost layer with the annealed copper wire that winds the insulation band carries out the pyrocondensation processing with 10KV cable heat-shrink tube;
At last, crimping being carried out at the two ends of annealed copper wire handles.
In the present embodiment, the insulation band is a 3M insulation band, and the length of annealed copper wire is 3 meters, adopts four layers of insulation band.
Drainage thread to making carries out withstand voltage test, and the withstand voltage level that 4 layers and above 3M insulation band twines all reaches 45kV, continues 1 minute, no flashover and punch-through.
Above embodiment only supplies to explain the present invention's usefulness, but not to the restriction of protection range of the present invention.The technical staff in relevant present technique field under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification, and the technical scheme that all are equal to also should belong within the category of the present invention's protection, is limited each claim.
