The problem with the light source is that it is difficult to repair or replace the light source because the wire indicator light is installed on the overhead wire. For this purpose, it was necessary to use a light source that does not require repair or replacement, or that has a life of at least several years.
In addition, the problem with the power supply is that it is difficult to connect the power supply line from the power supply to the wire indicator light if a separate power supply is provided, and a battery is installed in the wire indicator light to eliminate the need for the power supply line. Doing so makes battery replacement difficult. If a current transformer that obtains inductive power from the electric current of the overhead wire is used as a power source, a power supply line is not necessary and replacement is also unnecessary. However, the current transformer needs a toroidal coil that goes around the overhead wire in order to obtain electromotive force from the induced magnetic field around the overhead wire. It was difficult to fit the toroidal coil onto the overhead wire by mounting it externally. Moreover, when the power source is attached to the overhead wire, it is necessary to make the power source small in terms of the weight of the power source and the wind pressure received by the power source.

According to these known techniques, an LED (light emitting diode) is used as a light source, and the current transformer can be composed of a toroidal coil divided into two. LEDs have a longer life than incandescent lamps and discharge tubes, and can emit light with a relatively low voltage and small current. By using the LED as the light source, replacement of the light source is almost unnecessary and the power source can be downsized. In addition, by dividing the toroidal coil into two, it is easy to attach to the overhead wire.

No. 53145 shows a concrete structure of a marker light. According to this, a two-divided body that can be attached to an overhead wire is formed, a half-divided coil is provided in each divided body, and the half-divided coils are connected to each other by electrodes. An induction coil is formed around the overhead wire by connecting with a socket. Further, a plurality of LEDs are distributed in the circumferential direction, and electrode sockets are also used at the dividing points of the wiring.

Although it is conceivable to seal the connection part, sufficient waterproofness cannot be obtained even if sealing is performed after joining the two divided bodies.
Moreover, it is not easy to perform the sealing in the field work.

Since an induction magnetic field is formed in the annular core, electromotive force can be obtained by winding the coil around only one core. Moreover, since the coil does not require an electrode for connection, the coil does not have a problem of durability against rainwater. However, in this invention, the LEDs distributed in each of the two divided cases are connected by the connector. Since the iron core passes a magnetic field, it may be electrically separated, but the LED has to be electrically connected, so that the connector must be used. LE as mentioned above
Since D is turned on with a relatively small current, an increase in contact resistance due to corrosion and dirt of the electrodes becomes a big problem. Therefore,
This device also has a problem of durability against rainwater.

The whole case must be fixed to the overhead wire by assembling the two-part case at the same time. This fixing must be done firmly to withstand wind and rain. If the inner diameter of the case is larger than the outer diameter of the overhead wire when the two split cases are fitted together, the fixing becomes loose, which is inconvenient. Rather, when the overhead wire is sandwiched between the two split cases, it is advantageous for the two split cases to have a space between them for tightening. On the other hand, when the annular core of the toroidal coil has a gap, it is advantageous that the smaller the gap, the more preferably there is no gap. However, the condition for tightening the case and the condition for continuity of the annular core conflict with each other. If the two-piece iron cores come into close contact with each other when the case is tightened, the case cannot be tightened any more, and the holding force is reduced. If the two-piece iron cores are not brought into contact with each other in order to sufficiently tighten the case, a gap will be created, and the magnetic flux will leak from the gap, resulting in a decrease in the efficiency of obtaining electric power.

Two semi-annular magnetic cores each having a winding on a housing piece, a power source connected to the winding, and an LED light source to be turned on by the power source, each having no winding separate from the housing. The semi-annular magnetic core of (1) is provided so as to oppose each of the semi-annular magnetic cores having the above-mentioned windings via an overhead wire.

Forming an annular magnetic core. The induced magnetic field due to the current of the overhead wire in the annular magnetic core causes an electromotive force in the winding of the housing piece. The electromotive force causes the power source portion of the housing piece to turn on the LED light source of the housing piece. Also in the other housing piece, since the semi-annular magnetic core having the winding wire and the semi-annular magnetic core having no other winding wire form the annular magnetic core around the overhead wire, the housing piece is similarly formed. The power supply part of this is L of this housing piece

D光源の電力を得る電力効率が高まることになる。Further, by tightening both housing pieces with an appropriate force with a tightening member, the housing can be fixed while being fitted onto the overhead wire. On the other hand, since the semi-annular magnetic core having no winding is separate from the housing, it is attached separately from the fixing of the housing and can be attached regardless of the fastening of the fastening member.
Preferably, if a space for tightening is formed between both housing pieces, it becomes easy to control the tightening force of the tightening member, and the housing is securely fixed to the overhead wire. Further, if the inner diameter of the current transformer part composed of the semi-annular magnetic core having the winding and the semi-annular magnetic core not having the winding is made larger than the outer diameter of the overhead wire, the semi-annular magnetic core having no winding. When the semi-annular magnetic core having the winding and the winding are opposed to each other via the overhead wire, the semi-annular cores are brought into close contact with each other without being restricted by the overhead wire. Therefore, a ring-shaped magnetic core with no gap is formed, and LE from the current of the overhead wire
The power efficiency for obtaining the power of the D light source is increased.

Two annular magnetic cores having a half turn of the winding are formed. The winding of each annular magnetic core obtains an electromotive force according to the current passing through the annular core. However, when the electric wire indicator light is attached, the electric current flowing through the overhead electric wire is shunted to the housing of the electric wire indicator light. The current flowing through the housing does not contribute to the electromotive force because it passes through the outside of the annular magnetic core. When the annular magnetic core is arranged inside the housing, the shunt component that does not contribute to this electromotive force increases. When the annular magnetic core is arranged at the longitudinal end of the overhead wire of the housing,
Most of the current will pass through the ring core, contributing to the electromotive force. That is, by arranging the semi-annular magnetic core at the end of the housing in the longitudinal direction of the aerial wire, in the longitudinal direction of the aerial wire, the annular magnetic core, most of the housing including the fastening member,
The annular magnetic cores are arranged in order, and most of the electric current of the overhead wire is used for electromotive force, which improves power efficiency.

Therefore, the power supply unit 82 turns on the LED light source 34. On the other hand, since the semi-annular magnetic core 51 and the semi-annular magnetic core 52 form the annular magnetic core 71 around the overhead wire 6, the LED light source 33 is similarly turned on. That is, the LED light sources 33 and 34 are electrically turned on independently of each other by the electromotive force of the windings 81 and 83.
