Description
Technical field
The present invention relates to the anti-icing insulated conductor in power equipment.
Background technology
The icing phenomenon of plain conductor and insulated conductor is serious in the winter time, more than ice sheet can reach 10cm, electric power is carried and caused serious maintenance, the form of existing insulated conductor is, by the insulator coated wire core of ganoid drum type brake, vapor adhesion on insulator after, form water layer at insulator surface, then condense into ice sheet, and after the formation of water layer due to the absorption affinity between water, there is no the effect of drainage, the ice sheet of forming is ring-type ice sheet, the ice sheet so forming, be difficult for being eliminated, after needing hammer that ice sheet is broken into pieces, could remove, and general wire erection is in high-altitude, the efficiency of removing is extremely low.
Summary of the invention
The object of the present invention is to provide a kind of anti-icing insulated conductor, can play drainage effect to the water layer condensing, making the ice sheet condensing is column ice, is convenient to like this remove, and reduces the load of electric pole, reduces the harm of freezing to electric power facility.
Object of the present invention is achieved through the following technical solutions: anti-icing insulated conductor, comprise wire stylet and be coated on the outer field outsourcing insulator of wire stylet, outsourcing insulator and wire stylet form insulated conductor, the outer diametric plane of outsourcing insulator arranges several icing grooves along outsourcing insulator circumference trend, and the external diameter surface cover between the outsourcing insulator region between adjacent icing groove is provided with water conservancy diversion protruding ring.
Design principle of the present invention is: water conservancy diversion protruding ring is set, increase the contact area with air, make a large amount of moisture of moisture rapid condensation in humid air to water conservancy diversion protruding ring, utilize the water conservancy diversion efficiency of water conservancy diversion protruding ring and icing groove, under the effect of gravity, the downward gathering that water layer is a large amount of, assembles and forms water droplet in the groove surface side earthward of freezing, thereby in the time condensing, form icicle, make like this circuit moisture around be converted to fast icicle.And compared with the ring-type icicle that the icicle forming forms with traditional insulated conductor, because the contact area of icicle and icing groove is little, while adopting cleaning icicle, can clear up fast, in addition, because the contact area of icicle and icing groove is little, therefore in unit are, can only bear the icicle of certain length, in the time that icicle continues to increase, icicle is fracture automatically, and from the icicle of the microscler Cheng Xin of new life, so repeatedly.
As above structure, during said structure is placed and tested, experimental condition is: the closed environment of the low temperature that freezes, humidity, 1 day quiescent time, take out said structure observation, in each icing groove, can form an icicle, above-mentioned icicle is once striking fracture.
Preferably, the cross section of the groove that freezes is arc, and the cross section of water conservancy diversion protruding ring is fan-shaped, and cross section is the face forming along the cutting of wire stylet axis direction.Through experimental study, the cross section of the groove that freezes is arc, and when the cross section of water conservancy diversion protruding ring is fan-shaped, the diameter of icicle is less, and the icicle therefore forming is easy to knock off.
Preferably, through research, the span of the degree of depth of the groove that freezes is: 1cm to 2cm, the span of the width of the groove that freezes is: 1cm to 3cm.The growth length of icicle reaches 0.7 meter most and just there will be afterwards automatic phenomenon of rupture.
Preferably, the span of the minimum spacing between adjacent water conservancy diversion protruding ring is: 1cm to 3cm, and the difference in internal diameters of the external diameter of water conservancy diversion protruding ring and water conservancy diversion protruding ring is P, P span is: 1cm to 2cm.The growth length of icicle reaches 0.7 meter most and just there will be afterwards automatic phenomenon of rupture.
Preferably, the cross section of water conservancy diversion protruding ring is semicircle, and the cross section of the groove that freezes is semicircular arc.
The invention has the advantages that: simple in structure, can form icicle, prevent from forming ring-type ice sheet, be easy to break into pieces icing body, reduce the harm of power line.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Embodiment 1:
As shown in Figure 1-Figure 3.
Anti-icing insulated conductor, comprise wire stylet 1 and be coated on the outer field outsourcing insulator 2 of wire stylet, outsourcing insulator 2 and wire stylet 1 form insulated conductor, the outer diametric plane of outsourcing insulator 2 arranges several icing grooves 3 along outsourcing insulator 2 circumference trends, and the external diameter surface cover in outsourcing insulator 2 intervals between adjacent icing groove 3 is provided with water conservancy diversion protruding ring 4.
Design principle of the present invention is: water conservancy diversion protruding ring 4 is set, increase the contact area with air, make a large amount of moisture of moisture rapid condensation in humid air to water conservancy diversion protruding ring 4, utilize the water conservancy diversion efficiency of water conservancy diversion protruding ring 4 and icing groove 3, under the effect of gravity, the downward gathering that water layer is a large amount of, freezing, groove 3 is assembled and is formed water droplet towards a side on ground, thereby in the time condensing, form icicle 5, make like this circuit moisture around be converted to fast icicle.And compared with the ring-type icicle that the icicle forming forms with traditional insulated conductor, because the contact area of icicle and icing groove 3 is little, while adopting cleaning icicle, can clear up fast, in addition, because the contact area of icicle and icing groove 3 is little, therefore in unit are, can only bear the icicle of certain length, in the time that icicle continues to increase, icicle is fracture automatically, and from the icicle of the microscler Cheng Xin of new life, so repeatedly.
As above structure, during said structure is placed and tested, experimental condition is: the closed environment of the low temperature that freezes, humidity, 1 day quiescent time, take out said structure observation, in each icing groove 3, can form an icicle, above-mentioned icicle is once striking fracture.
Preferably, the cross section of the groove 3 that freezes is arc, and the cross section of water conservancy diversion protruding ring is fan-shaped, and cross section is to cut along wire stylet 1 axis direction the face forming.Through experimental study, the cross section of the groove 3 that freezes is arc, and when the cross section of water conservancy diversion protruding ring is fan-shaped, the diameter of icicle is less, and the icicle therefore forming is easy to knock off.
For the clear icing state of groove under which kind of condition that freeze, on the basis of said structure, the cross section of water conservancy diversion protruding ring is semicircle, and the cross section of the groove 3 that freezes is semicircular arc.
Spy has done following experiment: ambient temperature is identical with humidity, and constantly supplements experimental situation humidity, keeps humidity and temperature constant, and experimental period is 24 days.
Experiment 1: the degree of depth of the groove 3 that freezes is less than 1cm, the width of the groove 3 that freezes is less than 1cm; Experimental result is: form ring junction ice body, do not form icicle.
