[ 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, .

Instead of using the tie band 116, the first and second cases 112 and 114 may be integrally fastened using fastening means (not shown) such as bolts and nuts, It is also preferable to directly mount it on the distribution line 1. [

The iron core body 120 is also divided into two by the first and second iron core bodies 122 and 124 so that the iron core body 120 is divided into the first and second cases 112 and 114 And an induction coil 130 is wound on one side of the iron core 120 to generate an induction current when the power distribution line 1 is energized.

When the current information is received from the current sensing unit 140 for measuring the current of the induction coil 130, the control unit 160 included in the case 110 compares the current information with the overcurrent, (For example, device number and installation position information) and outputs the failure information.

The control unit 160 senses a current through the current sensing unit 140 at all times and senses a voltage through the voltage sensing unit 150 to receive unique information (for example, device number and installation position information) The normal information is transmitted to the reception device 210 or the intermediate information collector 220 of the central control room 200 at predetermined time intervals to inform the operation status.

The current sensing unit 140 converts the induced current value of the analog form into current information of the digital form. The voltage sensing unit 150 converts the induced voltage value of the analog form into voltage information of the digital form, 160, and the controller 160 determines whether an overcurrent is present or not using the digital current and voltage information.

The control unit 160 may be a microcomputer having a built-in memory for storing failure information including the unique information (for example, the device number and the installation location information) and the always-on information.

The signal transmitter 170 for transmitting the failure information generated by the controller 160 to the receiver 210 or the intermediate information collector 220 of the central control room 200 may be implemented in various ways such as a wired system or a wireless system However, the wireless system is used in consideration of ease of installation and the like.

More specifically, the signal transmitting unit 170 includes a wireless transmission module 172 for converting the failure information and the normal information output from the controller 160 into a wireless signal, And an antenna 174 for wirelessly transmitting data to the reception device 210 of the central control room 200 or the intermediate information collector 220.

The power supply unit 180 for supplying the driving power of the controller 160 includes a rechargeable battery 182. The rechargeable battery 182 serves to charge the induction current generated in the induction coil 130. [

Since the charging power source of the rechargeable battery 182 may not be suitable as a driving power source for the controller 160, it is preferable to further include a constant voltage IC and a DC / DC converter for stable power supply. / DC converter is a generally known constitution.

With this configuration, the rechargeable battery 182 of the power supply unit 180 is charged with the current induced in the induction coil 130 and supplied to the driving power supply of the control unit 160, so that even if there is no separate power supply, Power supply can be provided.

Hereinafter, the operation of the intelligent system of the distribution line according to the present invention will be described in detail with reference to FIGS. 1 to 5. FIG.

First, when an intelligent system 100 for a distribution line according to the present invention is installed on a distribution line 1 and electricity is supplied to the distribution line 1, the iron body 120 is magnetized and thereby induction coils 130 The induced current is generated.

When induction current is generated in the induction coil 130, power is supplied to the rechargeable battery 182 constituting the power supply unit 180 and the control unit 160 is driven by the power supply of the rechargeable battery 182.

The controller 160 receives the induced current and voltage information sensed through the current sensing unit 140 and the voltage sensing unit 150.

The control unit 160 compares whether the current information exceeds the set allowable current from the current sensing unit 140 that measures the current of the induction coil 130. If the current information exceeds the allowable current, It is determined that the current is energized, and the failure information including unique information such as the device number and the installation position is generated and output.

The failure information generated by the control unit 160 is converted into a radio signal in real time via the wireless transmission module 172 constituting the signal transmission unit 170 and transmitted through the antenna 174 to the reception apparatus of the central control room 200 (210) or the intermediate information collector (220).

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 the failure information is transmitted to the intermediate information collector 220 connected to the receiving apparatus 210 or the receiving apparatus 210 of the central control room 200, the central control room 200 confirms the installation position of the apparatus through the failure information And the worker is promptly put in the work 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.

In the present invention, the configuration of the temperature controller 300 for appropriately adjusting the internal temperature of the case 110 as shown in FIG. 6, including the above configuration, is further implemented.

The temperature control unit 300 may control the temperature of the control unit 160 or the like that may be generated while the internal temperature of the case 110 is hermetically sealed due to generation of induction current in the induction coil 130, To prevent operation errors and the like.

The temperature controller 300 includes a temperature sensor 310 for sensing an internal temperature of the case 110, a suction unit 320 for sucking outside air into the case 110, (Not shown) to the outside.

The suction and discharge means 320 and 330 are operated under the control of the controller 160 according to the temperature sensed by the temperature sensing sensor 310 so that air can smoothly pass through the inside of the case 110, So that heat dissipation and cooling for the case 110 can be effectively performed.

The temperature sensor 310 may be disposed inside the case 110.

The suction unit 320 includes a suction pipe 321 having one end connected to the inside of the case 110 and sucking outside air to the other end and a suction fan 322 connected to the suction pipe 321 .

The discharge means 330 includes a discharge pipe 331 having one end connected to the inside of the case 110 and discharging air to the other end and a discharge fan 332 connected to the discharge pipe 321.

The case 110 has the suction pipe 321 connected to one end thereof and the discharge pipe 331 connected to the other end thereof, so that external air flows from one end to the other end, and ventilation can be performed.

It is preferable that one of the suction and discharge pipes 321 and 331 is connected to the first case 112 and the other pipe is connected to the second case 114.

For example, the suction pipe 321 has one end connected to the lower end of the other end of the case 110, that is, the other end of the first case 112, and the other end directed downward, Form.

One end of the discharge pipe 331 is connected to one end of the case 110, that is, one end of the second case 114, while the other end of the discharge pipe 331 is directed downwardly.

This is because the suction and discharge pipes 321 and 331 are staggered from each other to increase the contact area between the air introduced into the case 110 and the case 110, So that cooling can be effectively performed.

In order to prevent the rain or the like from flowing into the case 110 through the other ends of the opened suction and discharge pipes 321 and 331,

The suction and exhaust fans 322 and 332 are driven by receiving power from the power supply unit 180 and the controller 310 controls the operation of the suction and exhaust fans 322 and 332 in accordance with the temperature sensed by the temperature sensor 310. [ .

The control unit 160 may control the suction and exhaust fans 322 and 332 to be driven simultaneously or one of the fans may be driven.

In other words, the controller 160 controls the suction and discharge fans 322 and 332 to be driven when the temperature is sensed by the temperature sensor 310. When the temperature of the suction and discharge fans 322 and 332 is lower than a predetermined temperature, 322 and 323 are stopped.

The power distribution system intelligent system 100 can appropriately adjust the internal temperature of the case 110 by cooling the induction coil 130 as well as the iron core 120 and the like.

Therefore, the intelligent system 100 for the distribution line can prevent a failure or an operation error of the control unit 160 due to an increase in the internal temperature of the case 110.

The discharge means 330 may further include a check valve 333 provided at the other end of the discharge pipe 331.

The check valve 333 is opened by the pressure of the air passing through the discharge pipe 331 according to driving of the suction and discharge fans 322 and 332 so that the internal air of the case 110 can be discharged to the outside On the other hand, foreign matter or the like is prevented from flowing into the case 110.

The suction unit 320 may further include a filter 323 provided at the other end of the suction pipe 321.

The filter 323 includes a net body 324 for blocking foreign substances contained in the air from passing therethrough and blocking the other end of the open suction pipe 321 and a nonwoven fabric 325 surrounding the net body 324.

The netting 324 stably supports the nonwoven fabric 325, and the nonwoven fabric 325 prevents foreign matter contained in the air from passing therethrough.

In addition, the nonwoven fabric 325 can easily filter the foreign substances that are contained in the nonwoven fabric 325, thereby preventing moisture from flowing into the interior of the case 110.

Therefore, the temperature controller 300 can prevent a malfunction of the controller 160 and the like, which may occur when foreign substances contained in the air are introduced into the case 110.
