Outer contact 4 includes at least one of which；
Every layer of outer contact 4 is formed by aluminum Baogang monofilament is stranded.
Specific embodiment, see Fig. 1: the outer ring surface of noninductive twisted-pair feeder 1 is stranded to be disposed with a rustless steel light unit 2 and five
Root the first aluminum-cladding stranded wire 3, a rustless steel light unit 2 and five stranded formation core arrangement outer layers 7 of first aluminum-cladding stranded wire 3
Outer face arrange one layer of outer contact 4, outer contact 4 is formed by ten second aluminum-cladding stranded wires 5 are stranded, noninductive twisted-pair feeder
1st, a rustless steel light unit 2 and five first aluminum-cladding stranded wire 3 combinations form conductor inner core 6, and noninductive twisted-pair feeder is spaced one section
Distance is provided with external-connected port (in figure is not drawn into, and is arranged) according to practical situation.
Its advantage is as follows: (1) conventional AC ice-melting method directly takes electric network source, and in current electrical network, 300mw generates electricity
Unit disclosure satisfy that the line ice-melting reactive requirement of 200km length.Because lead inductance numerical value is much larger than resistance, exchange ice-melt consumption
Reactive capability big, the power supply capacity needed for ice-melt is 5-20 times of direct current, far beyond system tolerance range, may impact be
System stability.And huge faradic current can be produced in galvanization.Little based on twisted-pair feeder electromagnetic interference, inductance is little, energy
The advantages of consume little, can effectively reduce the electromagnetic interference of ground wire deicing process using twisted-pair feeder as opgw ice-melt thermal source；
(2) alternating current power supply of electrical network is converted to, by rectifying installation, the unidirectional current that can be used for ice-melt by DC ice melting method, plus
In icing circuit.Install deicing device additional, these devices include alternating current power supply, rectifier transformer, fairing and some protections and set
Standby composition.Need during work to be transported to these equipment and treat ice-melt area, and line ice coating mostly occurs in clammy mountain area, weather
Inclement condition, has inconvenient traffic, and DC de-icing device is delivered to and is limited by road conditions, vehicle condition and meteorological condition at line ice coating, temporarily
Wiring is likely to occur problem, and uncertainty is many, and before ice-melt, operation is many.The opgw exchange ice-melting method studied herein is by ice-melt loop
It is embedded in opgw, in deicing processes, for icing section line ice coating, ice-melt scope typically occurs between several strain sections,
Existing opgw is grounded or segmented ground by base through anchor support, anchor support spacing 5km about, the through-flow satisfaction of ice-melt between anchor support
The resistance to voltage levels of enamel-covered wire；
(3) there is not reactive loss in DC ice melting, power supply capacity is required much smaller than exchange, in the higher ranked line of electricity
Road ice-melt is used must be than wide.In actual ice-melt work, the development of DC ice melting work there is also restraining factors.First, melt
Ice high cost, for current level, the investment of direct current dress is big.Secondly, DC ice melting can not directly use electric network source, needs
Ice-melt loop just can be passed through through the operation such as rectifying and wave-filtering, the input cost of this kind of ice-melting ground wire is low；
(4) exchange ice-melt common method includes excess current de-icing method and short circuit current ice-melting method, for transmission line of electricity, excessively electric
Stream ice-melting method is under system normal running (operation) conditions, increases line current, increases circuit caloric value, melts icing.Short circuit current
Ice-melting method is that three-phase shortcircuit circuit is carried out with through-flow ice-melt operation, line outage during ice-melt.This structure do not need opgw with big
Ground, joint use ground wire or transmission pressure and form loop, during ice-melt, from becoming ice-melt loop, transmission pressure can normally be transported
Row energising, does not affect wire normal work.
Above specific embodiment of the utility model is described in detail, but content has been only what this utility model was created
Preferred embodiment is it is impossible to be considered the practical range for limiting this utility model creation.All creation according to this utility model is applied for
The impartial change that scope is made and improvement etc., all should still belong within patent covering scope of the present utility model.
