A relatively high voltage current flows through the distribution line installed on the pole, and the distribution line is connected like a mesh.

If the insulator such as the insulator of the electric pole fixing the connection line connected with the complex structure is deteriorated or the insulation of the distribution line is destroyed due to burning due to lightning, contact with trees or algae, the switchgear such as substation or power supply protective device operates Power supply may be cut off to cause a power outage or an overcurrent may cause a safety accident and the operation of industrial equipment may be interrupted and the operation of household appliances such as a refrigerator or a washing machine in the home may be stopped, If a failure (failure) occurs in the distribution line, rapid recovery should be done in a short time.

However, since the discovery of the failure point to the distribution line is not performed automatically at present, there is no way to quickly find out the overcurrent flowing in the distribution line where the insulation is broken, It takes a lot of time.

First, the case 110 is formed in a cylindrical shape as a whole, and a through hole 110a through which the power distribution line 1 passes is formed at the center, so that the case 110 can be easily installed at any position of the previously installed power distribution line 1. [ The first and second cases 112 and 114 may be divided into a first structure and a second structure.

When the first and second cases 112 and 114 are fastened to each other, the first and second cases 112 and 114 are fastened to each other by using a tie band 116 made of a metal as fastening means, .

The controller 160 wirelessly transmits the voltage and current information, which is the voltage and current value, to the receiver 210 or the intermediate information collector 220 of the central control room 200 in real time or at predetermined time intervals.

In this case, when fixed information is transmitted to the intermediate information collector 220 connected to the receiving apparatus 210 of the central control room 200 or the receiving apparatus 210 of the central control room 200, The installation position of the apparatus is confirmed and the worker is promptly put in to recover the distribution line 1.

The intelligent system 100 for a power line according to the present invention is driven independently for a predetermined period of time by using the power of the rechargeable battery 182. Therefore, even when the power line 1 is not energized, 1) can be transmitted, and stable signal transmission is possible.

When information is recorded in such a frame unit, the size of each field, the size of each frame, the size of each word, and the size of each byte can not be deciphered, which is the same as encryption. Also, It is possible to safely protect recorded information from noise or the like.

In such a configuration, the information on the current and voltage of the power distribution line that supplies electricity is measured in real time and notified to the central control room, so that the place where the overcurrent is generated in the case of the overcurrent due to the failure is immediately detected, And it is advantageous to shorten the failure recovery time to the power distribution line because the place of the overvoltage can be immediately detected when the overvoltage occurs. In addition, there is an advantage that the driving power is secured from the distribution line using an electromagnetic induction method and is driven independently and semi-permanently without receiving a separate power source. In addition, it is possible to prevent a slip phenomenon that may occur when an excellent lamp enters the inside of the case, a generation fault of induction current, and the like, as well as to prevent a failure of a control unit and a signal transmission unit caused by electromagnetic waves generated by an induction coil, There is an advantage to be able to do.
