[0001] DESCRIPTION [0002] BREAKDOWN POINT DETECTION SYSTEM OF DISTRIBUTION LINE [

There is a wire line and an underground wire in the distribution line. In general, it is common that electric power is supplied to a home, a shop, a small factory, etc. by a working line.

The underground power distribution line is a method of inserting a power cable underground and distributing it as an insulated conductor. However, it has a merit that it is better in appearance and less trouble than a processing power distribution line, but it has a disadvantage that construction cost and equipment are expensive, .

Domestic power distribution lines use almost the line method from the economic point of view, but there are frequent failures due to power distribution lines, and there is a problem that the state of the lines must be visually checked along the roads and alleys to find broken distribution lines.

In particular, when a fault occurs due to an obstacle such as a roadside or a building or a fault caused by a minute scratch on a power line, it is difficult to detect a fault section of the power line, and the detection time is also long.

In addition, when the fault section of the distribution line is complicatedly constituted by a plurality of branch points or the like, it is impossible to visually identify the fault section or the detection time is long, thereby increasing the wide-range power interruption time.

However, such a conventional distribution line fault display device has a problem in that it is difficult to distinguish by sunlight or the like because it is dependent on only the light generated from the lamp part when checking with a broken distribution line.

In addition, although a light intercepting unit for intercepting light incident from the outside is provided, it is possible to shut off the light generated in the lamp unit together with the light interception, so that it is difficult to confirm a broken distribution line.
