本発明は、架空地線に雷が堆積するの全防止する架空地
線の融雪方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a snow melting method for an overhead ground wire that completely prevents lightning from accumulating on the overhead ground wire.

融雪対策が進められていないものであった。Conventionally, overhead power transmission MAKs installed in areas with heavy snowfall have been equipped with various measures to prevent snow buildup in order to prevent various accidents caused by snow buildup during snowfall. Similarly, almost no snow melting measures have been taken for overhead ground lines where there is a risk of snow accretion.
本発明は上記の事情に鑑みなされたもので、特に架空地
線に対する着雪？有効に防止し得る架空地線の融雪方法
全提供すること全目的とするものである。The present invention was made in view of the above circumstances, and specifically concerns snow accumulation on overhead ground wires. The object of the present invention is to provide a method for effectively preventing snow melting from overhead ground wires.

In addition to electrically insulating it from other wires as an insulator,
A loop-shaped closed circuit extending over the entire length of the overhead ground wire is formed by the at least two insulated wires, and electricity is applied to the closed circuit to heat the overhead ground.

線を維持することができる。Embodiments of the present invention will be described below with reference to FIGS. 1 to 3. As shown in FIG. Two of the many strands constituting the wire 1 are insulating elements having an electrically insulating surface 5 as shown in FIG. 4A to electrically insulate it from other elements M4. Since aluminum-covered #1 wire or aluminum alloy wire is often used as the element ring of the overhead ground wire 1, this insulating element M4A can be formed by alumite-treating its surface. Like this 1
According to the insulating element m4A in which the electrically insulating surface 5 is formed by alumite treatment, the insulating surface 5 does not melt even at high temperatures, and its outer diameter becomes thicker than other elemental wire flaws. Since there is no strand, it is possible to maintain an overhead ground wire with a stable strand structure.

Is there a loop-shaped M circuit inside? Since the overhead ground wire l is heated by flowing the current [E], it can be applied even when there is only one overhead ground wire l, and it can also be used as a reciprocating conductor if there are two overhead ground wires. Can the inductance be extremely small compared to forming a loop-shaped closed circuit using an expensive compensation capacitor? It is possible to obtain the desired heat generation 1tt without using a current t-flow.
