Abstract
An ice-breaking insulated wire against galloping comprises conductors 3 and an insulation layer 2, wherein two symmetric convex wings 4 are arranged outside the insulation layer. The ice-breaking insulated wire against galloping is applicable for an outdoor overhead power circuit in special rain and snow weathers; in a rain and snow windy weather, ice is easy to frozen outside the insulation layer of the wire, and the ice layer outside the wire is divided into two halves by the convex wings arranged outside the insulation layer and separated to throw away by means of wind; and moreover, the two symmetric convex wings outside the insulation layer also can play a wire balancing effect.
Description
Technical field
The present invention relates to field of cables, be specifically related to that one can open ice, Anti-galloping insulated conductor.
Background technology
Annual 3 to April is that China's weather turns a warm astable season by trembling with fear, weather feature be sometimes hot and sometimes cold, snow with a mingling of rain coexist, the origin cause of formation that strong wind suddenly and wind direction are conductor galloping.The condition formed is that initial stage weather temperature is more than 0 DEG C, there is the weather of light rain, air humidity is very large, wire is coated with a large amount of moisture, there was an abrupt change in weather afterwards, with strong wind, temperature sharply declines, be attached to moisture on wire to freeze immediately and moisture in absorbed air, ice sheet is thickeied gradually, sharply cooling afterwards makes rain progress of disease Cheng Xue, snow adheres to again on icing wire, make wire to be formed the ice and snow layer constantly thickeied, ice and snow coated on wire makes line load continue to increase, under large wind action, the resonance defining wire is waved, and constantly thicken along with the thickness of coated ice and snow, resonance frequency changes, amplitude of waving also is continuing to increase.
Outdoor aerial power circuit waving under special temperature environment brings high risks to electric power system, energy research Anti-Oscillation Measures is all dropped in countries in the world for many years, such as: circuit installs conductor spacer additional, harmonic elimination damping hammer is installed additional for eliminating resonance, circuit rounded projections arranged, electric heating ice-melt etc., but effect is all undesirable.
The harm that line oscillation brings is huge, cause circuit fall tower, fall bar, broken string, swinging cross short circuit, occurrence of large-area power outage.Such as, a sleety weather of south China in 2005 causes many provinces and cities large area blackout.A sleety weather (6 ~ fresh gale is tide cruelly) in Dalian on March 4th, 2008 causes national grid large-area power-cuts, only have at that time one, Huaneng Group power plant to Dalian the island operation state for electric forming.
Summary of the invention
For solving the problem, the invention provides one and to open ice formula Anti-galloping insulated conductor, having wire and insulating barrier, it is characterized in that: outside insulating barrier, be provided with two symmetrical convex wings.The present invention is designed with two convex wings on the insulating layer, its effect makes ice and snow coated on wire become two semicircles, the effect of division icing is played from mathematics and physics angle two convex wings, by means of the wind-force in air, be easy to icing to be separated get rid of, complete the mode of opening ice, connect a convex wing symmetrical, make overhead power line held stationary.
Accompanying drawing explanation
Fig. 1 is common insulated conductor icing schematic diagram;
Fig. 2 is the formula Anti-galloping insulated conductor schematic diagram that opens ice;
Wherein, 1-ice sheet, 2-insulating barrier, 3-conductor, the convex wing of 4-.
Embodiment
As shown in Figure 1, 2, one opens ice formula Anti-galloping insulated conductor, has conductor 3 and insulating barrier 2, is provided with two convex wings 4 of symmetry outside insulating barrier.The present invention is applicable to the outdoor aerial power circuit under sleet special weather, and at sleet strong wind weather, wire insulation easily freezes outward, and the ice sheet outside wire is split into two halves by the convex wing that insulating barrier is arranged outward, by wind-force, is separated by the ice sheet outside wire and gets rid of.And two convex wings of symmetry outside insulating barrier can also play the effect of equalizing contactor.
Claims (1)
1. the formula that opens ice Anti-galloping insulated conductor, has conductor and insulating barrier, it is characterized in that: outside insulating barrier, be provided with two symmetrical convex wings.
