Abstract
The utility model discloses a deicing lead which comprises an inner-layer aluminum conductor that is obtained through twisting a plurality of aluminum single wires. A composite single-wire layer which is formed through coating low-curie-point alloy on the surfaces of the aluminum single wires is provided outside the aluminum conductor. The deicing lead provided by the utility model can sense AC magnetic field generated by AC current of the power transmission line for generating heat when the surface temperature of the lead is lower than the curie point 0 DEG C, thereby obtaining a purpose of automatically melting ice. The low-curie-point alloy deicing lead provided by the utility model can automatically perform deicing according to weather condition and does not require maintenance by personnel. The deicing lead can be used and functions for long time after one-time mounting.
Description
Technical field
The utility model relates to the transmission line aerial condutor, refers in particular to a kind of low curie point alloy deicing lead in cold or heavy icing area use.
Background technology
Because accumulated snow, and the weight of power transmission line is increased during the many regional overhead transmission line of general snowfall, perhaps that load takes place is unusual when accumulated snow comes off, and accident such as cause that power transmission line is broken, short circuit and iron tower collapse has a strong impact on the safe operation of electrical network.State Grid and relevant departments all will expend great amount of manpower and material resources annual winter and prevent ice and snow harm in the circuit for this reason.How reducing icing, reduce conductor cord disconnection and short circuit thing ore deposit, make power network safety operation, is the problem that present overhead transmission line presses for solution.
The utility model content
Technical problem to be solved in the utility model provide a kind of can automatic defrosting the low curie point alloy deicing lead of snow, solved problems such as icing, conductor cord disconnection and short circuit thing ore deposit, make power network safety operation.
A kind of deicing lead described in the utility model comprises the aluminium conductor of internal layer being provided with the single line composite bed outside aluminium conductor, and described single line composite bed is to be made of the aluminium single line that many surfaces are coated with the low curie point alloy.
Further improve, described aluminium conductor is by some stranded the forming of aluminium single line.
The beneficial effects of the utility model:
Low curie point alloy deicing lead described in the utility model, be to plate the low curie point alloy material on aluminium single line surface, the alternating magnetic field that its alternating current that can respond to transmission line produces produces heat, reach the purpose of automatic defrosting snow, guarantee power network safety operation.And can carry out deicing voluntarily according to weather condition, the personnel that need not safeguard or maintenance that once mounting can be used and play a role for a long time.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of deicing lead described in the utility model comprises the aluminium conductor 1 of internal layer being provided with single line composite bed 2 outside aluminium conductor 1, and described single line composite bed 2 is to be made of the aluminium single line that many surfaces are coated with the low curie point alloy.
The utility model provides a kind of thinking and implementation method of deicing lead; concrete application approach is a lot; the above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvement, these improvement also should be considered as protection range of the present utility model.
Claims (2)
