Abstract
The utility model relates to an automatic ice-melting device for transmission line conducting wires without power-cut, which belongs to the line protection and is composed of a spring device for detecting ice, a switch for melting ice, a conducting wire for melting ice, etc., wherein, the conducting wire for melting ice is composed of a steel-core wire, an aluminum wire and an insulating layer between the steel-core wire and the aluminum wire. When the conducting wire of a transmission line has no ice, electric current passes through the aluminum wire; when the conducting wire of the transmission line has ice, the conducting wire is droopy by the effecte of the ice to drive the spring device for detecting ice. Then, the switch for melting ice is driven by operating a handle of the switch to switch off the electric current leading to the aluminum wire. The electric current is caused to pass through the steel-core wire. Owing to steel-core wire has large resistance value, the steel-core wire is heated and melts the coated ice on the leading wire. The power transmission returns to the normal state after the ice is melted.
Description
The utility model belongs to the line protection class, and its device can protect the harm that icing caused on the overhead transmission line.
The many areas of China can't solve owing to overhead transmission line icing problem, and cause down shaft tower, broken string road accident, cause and cause large-area power-cuts, influence industrial and agricultural production and residential electricity consumption.Be to solve the icing problem, the former electric power system molten ice method of short circuit of mainly taking to have a power failure though this method is effective to the lead ice-melt, need have a power failure for a long time and employ a tremendous amount of manpower, and changes the mode of connection, complicated operation, dangerous.Molten ice transformer belt electric smelting ice method though can melt ice under not power failure situation, needs the molten ice of large-scale special use transformer station, and investment is big.The molten ice of a kind of LC that I once developed material, the molten ice that can not have a power failure, and molten ice is effective, but the material cost height is powerless during lead heavy ice.
The utility model is intended to design a kind of transmission line wire automatic melting ice device that do not have a power failure, and adopts this device can guarantee the lead molten ice of realizing not having a power failure automatically under icing, heavy ice situation, and cost low, easy for installation, electric power system is had no adverse effects.
Installation of the present utility model realizes in the following manner, the transmission line wire automatic melting ice device that do not have a power failure is formed by surveying ice spring assembly 2, molten ice switch 3 and molten icing lead 5, molten ice spring assembly one terminal insulator string 1, master cock handle 7, steel core wire 9 in one end and the molten icing lead 5 is connected, draw two leads from common power transmission line 6, steel core wire with molten icing lead 5 is communicated with, and one is passed through molten ice switch 3 and is communicated with the aluminum steel 11 of molten icing lead 5.
Content of the present utility model is described in detail in detail with reference to the accompanying drawings.
Fig. 1, the utility model structure and scheme of installation,
Fig. 2, the molten ice spring assembly structure vertical view of Fig. 1.
With reference to Fig. 2, molten ice spring assembly 2 is made up of spring deck 12, spring 13, crust of the device 14, gold utensil union end 15.Gold utensil union end one end connects with insulator string 1 by gold utensil, and an end connects with the steel core wire 9 of molten icing lead 5 by gold utensil 4.The spring deck is fixed on the shell 14 by molten icing lead one end, is movable end by insulator string 1 one ends.
With reference to Fig. 1, molten icing lead 5 is made up of three parts, and the centre is the big steel core wire of resistance 9, and the outside is the little aluminum steel of resistance 11, and insulating barrier 10 is arranged between steel core wire and the aluminum steel.Common power transmission line 6 and lead-out wire, aluminum steel conducting place of lead-out wire and molten icing lead 5 is provided with wire clamp 8.
With reference to accompanying drawing, after the utility model is installed in the power transmission line highway section of the molten ice of needs, when transmission line does not have ice or few ice does not have when influence to circuit, because the resistance ratio steel core wire of aluminum steel is much smaller, electric current then only by aluminum steel 11, melts the same normal the sending with common power transmission line of icing lead.After on the molten icing lead certain thickness icing being arranged, lead is subjected to the influence of icing sagging, the movable end that drives the spring deck is moved to stiff end, compression spring 13, drive molten ice switch 3 by master cock handle 2 again, disconnect the electric current that leads to molten icing lead aluminum steel, it is flow through from steel core wire 9, reach the purpose of carrying certain electric power.Because the steel core wire resistance value is big, when electric current passed through, the lead heating was enough to melt the icing on the lead.After the ice on the lead has melted, survey and ice the spring assembly reinstatement, and drive the reinstatement of molten ice switch, then recover the former electric situation of normally sending.
The utility model can make icing, heavy ice fusing on the transmission line wire under power-off condition not, avoid causing down shaft tower, the road of breaking, and causes large-area power-cuts, influences the harm of industrial and agricultural production and resident living.After the ice fusing, the utility model fails, and recovers normal power supply.Adopt the utility model cost low, easy for installation, electric power system is had no adverse effects, be fit to apply.
