The present invention relates to a distribution line protection panel of underground cables, and in particular, it is possible to quickly determine whether there are any abnormalities of a plurality of underground cables carried in underground pipes buried underground, and The present invention relates to a distribution line protection panel for underground wires that can be located and quickly maintained.

Generally, power lines are installed in the telephone poles or buried in the ground to supply electric power. The ground and aerial construction methods are much more economical than construction methods in the ground, considering the constructability, cost, and construction period. There is an advantage that can be simplified, but the building is very close to the dense place, such as downtown, the installation is quite difficult disadvantages, when installed in the underground or in the case of demanding high current in the city.

For example, in a power plant including a thermal power plant, a hydroelectric power plant, and a nuclear power plant, electricity generated at a voltage of about 20,000 V is boosted to ultra high voltage (154 KV or 345 KV) suitable for transmission. Transmitted to the primary substation. The primary substation lowers the super-high voltage electricity to 22.9 KV, which is the special high voltage, and transmits or distributes the electricity to the general customers along the secondary substations or distribution lines located near the large capacity customers.

Electricity distributed from the primary substation or secondary substation is transmitted or distributed to the receiving facility of each customer through the transmission and distribution system consisting of overhead distribution line and underground distribution line. It is used for industrial and home use.

Generally, in the transmission and distribution system using the ground, the underground pipe is arranged in the ground so as to be spaced at regular intervals in the up, down, left and right directions, and a cable or an underground wire is installed to transmit electric power to the hole formed in the underground pipe. Transmitting and distributing extra high voltage through. The above-mentioned underground pipes should be kept in a regularly spaced position, since it is difficult to maintain a uniform spacing between the ground and the ground.

In such underground pipes, a plurality of shelves are arranged at regular intervals to accommodate a plurality of wires (for example, high-voltage wires, communication cables, etc.) at regular intervals. And supply of communication information.

In the 'distribution line forming panel of the special high voltage underground wire' filed as a patent application No. 10-2008-0055447 (2008.06.12), a plurality of supporting plates 330 are installed inside the underground pipe, and the flow of underground wires is prevented. A bolt-shaped release preventing member 334 protrudes from the base plate.

However, this configuration is not perfect, and the underground pipes are distorted or flown by natural disasters such as earthquakes and ground erosion, and as a result, some underground wires carried on the base plate (racks) fall to the bottom of the underground pipes and are damaged or flooded. There was a problem that the life is shortened.

In addition, when such a problem occurs, the ground worker has a problem in that it takes a lot of maintenance cost and time because it is not easy to determine which underground wires of which underground pipes have problems.

In order to solve the above problems, an object of the present invention is to understand the location of the underground pipe and the location of the damaged underground wire quickly when a natural disaster occurs of the underground wire is implemented to reduce the maintenance cost and time To provide a distribution line protection panel.

Another object of the present invention is to provide a distribution line protection panel of underground wires having a shelf for firm fixing of unit underground wires.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The following terms are defined in consideration of the functions of the present invention, and may be changed according to the intentions or customs of the user, the operator, and the like. Therefore, the definition should be based on the contents throughout this specification.

1 is a cross-sectional view showing the internal structure of the underground tube 10 according to an embodiment of the present invention, Figure 2 is a partial perspective view of the shelf 30 and the sensing panel 40 of Figure 1 according to the present invention 3 is a cross-sectional view showing main parts of a shelf and a sensing panel of FIG. 1 according to the present invention installed on a support.

1 to 2, the underground pipe 10 is formed in the form of a rectangular box having an internal space that the operator can enter and maintain. For example, the width and length of the underground pipe may be manufactured to have a length of about 2m each. In the receiving space 11 for accommodating the underground wires of the underground pipe 10, a base 20 having a predetermined width and height is installed at a bottom thereof, and a support 21 is installed in a vertical direction at the center of the base 20. One side of the support 21 is provided with a control unit 50 in the form of a box. The control unit 50 and the support 21 described above are installed to be connected to each other.

The support 21 is provided with shelves 30, R1, R2, and R3 of a predetermined interval and a predetermined width, and a plurality of unit underground wires L1, L2 ... L8 is arranged at regular intervals. According to the present invention, the underground wires L are disposed to have a predetermined interval and are in a state of being seated in the seating groove 301 formed in the longitudinal direction on the upper surface of each shelf 30.

The above-mentioned underground wires L may be arranged so that the flow is interrupted when seated on the shelf 30. Therefore, as shown in Figure 1, the mounting groove 301 formed in the shelf 30 is formed deeper than the radius R of the unit underground wire L to be applied, when the underground wire L is seated in the mounting groove 301 underground wire More than half of the outer circumferential surface of L was allowed to be seated in the seating groove 301.

Therefore, when the worker seats the underground wire L in the seating groove 301, the operator may apply the predetermined force toward the seating groove 301 to fix the underground wire L in the seating groove 301 by a fitting method.

On the other hand, the sensing panel 40 is mounted below each shelf 30 described above. On the surface in contact with the shelf 30 of the sensing panel, a plurality of sensors are disposed in a position corresponding to the mounting groove 301 formed in the longitudinal direction on the shelf 30. The above-mentioned sensor is preferably a photo sensor S, the photo sensor S is preferably made of a general configuration provided with a light transmitting portion (light emitting portion) and a light receiving portion. The optical signal output from the light emitting unit of the photosensor S is reflected on the surface of the object or underground wire (L) and received by the light receiving unit. That is, it is possible to detect a case in which the light receiving unit of the photosensor S does not receive the optical signal output from the light emitting unit.

The photosensor S preferably emits and receives an optical signal of any one color selected from the representative seven colors of infrared, ultraviolet or rainbow.

Accordingly, the shelf 30 is preferably formed of a transparent resin or at least a portion where the photo sensor S is disposed. Alternatively, when the shelf is formed of a metal material, the position corresponding to the photo sensor S may be formed as an open hole.

The control unit 50 is fixed to the upper side of the highest part of the underground pipe 10, in order to preempt the safest position when the underground pipe is flooded. The control unit 50 is electrically connected to the sensing panel 40 corresponding to each shelf 30, and according to the sensing operation of the sensing panel 40, the corresponding underground pipe 10, the shelf 30, and the corresponding Information on the presence or absence of abnormality of the underground wire L can be read and the information about the underground wire L can be transmitted wirelessly to the ground worker.

Referring to Fig. 3, the support 21 has a hollow portion 211 in the form of a pipe. Therefore, the electric lines of the sensing panel 40 fixed to the support 21 pass through the hollow portion 211 of the support 21 to the control unit 50. That is, the complexity of the separate external wires is excluded, and to prevent the malfunction of the control unit due to the flooding.

Therefore, in the case of deviation of the location of a specific underground wire which may be caused by a natural disaster such as an earthquake or ground erosion and the position of the shelf 30 is misaligned, the photo sensor S disposed below the control unit 50 performs a sensing operation. ), The control unit 50 can transmit the abnormality information of the underground wire L to the worker on the ground.

4 is a block diagram showing the relationship between the sensing panel 40 and the control unit 50 of FIG. 1 according to the present invention.

Referring to FIG. 4, the control unit 50 according to the present invention includes a control unit 51, an abnormal positioning unit 52, and a wireless transmitter 53.

The abnormality positioning unit 52 receives a sensing signal of a corresponding underground wire L having an abnormality among a plurality of photo sensors S disposed on the sensing panel 40, and provides position information of the shelf 30 according to the sensing signal and the corresponding information. The information of the underground pipe 10 is provided to the control unit 51.

For example, when the underground wire L is separated from the seating groove 301 of the shelf 30, the photo sensor S of the sensing panel 40 may detect this and provide it to the abnormal positioning unit 52. The sensing information may be a concept including location information of the unit underground wire L, location information of the shelf 30, and unique information of the underground pipe 10. Therefore, the abnormality position confirmation part 52 detects such a detection signal, and provides the control part 51 to the underground pipe 10 information, the shelf 30 information, and the information of the said underground wire L.

The control unit 51 transmits the abnormality information on the underground wire L provided by the abnormal positioning unit 52 by using the wireless transmission center 53. The control unit reads a detection signal for the underground wire L provided from the abnormal position checking unit 52, and the operator controls the corresponding position of the underground wire L, the corresponding position of the shelf 30, and the information of the specific underground pipe 10 accordingly. The wireless transmitter 53 can be converted into a signal that can be read and controlled.

More preferably, the control unit described above may be a concept including a storage unit. Therefore, by providing the user with pre-stored information that stores various additional information such as the role and function of the underground cable, the importance of the underground cable where an abnormality is detected can also be provided.

For example, when the sixth underground wire L6 of the second shelf R2 of FIG. 1 is detached from the shelf, the corresponding photo sensor S of the sensing panel installed at the lower side detects that the underground cable is detached. For example, the photo sensor of the sensing panel may include a light emitting part and a light receiving part. When the underground wire is placed on the transparent shelf, the light source irradiated from the light emitting part is reflected by the underground wire and received by the light receiving part so that the underground wire corresponds to the light receiving part. You will detect that you are not leaving the seating groove.

However, when the underground wire L is separated from the seating groove 301, the light receiving unit irradiated by the light emitting unit and receiving the light source reflected by the underground wire does not receive the light source reflected by the departure of the underground wire. Is provided to the abnormal positioning unit 52 of the control unit 50.

Therefore, the abnormality positioning unit 52 checks the positional information of the detected photo sensor S and provides the information to the controller 51. The control unit transmits the information (for example, information that an abnormality has occurred in the L6 underground wire of the R2 shelf of the Nth underground pipe, and the underground wire is an extra high voltage wire provided to the 00 area) through the wireless transmitter 53. Send it out.

Therefore, the worker working on the ground immediately monitors this monitoring information, so that the position of the corresponding underground pipe 10 and the shelf R2 where the underground wire L6 with the abnormality in the underground pipe are located and the type of the underground wire (in the 00 area) The outgoing high voltage wires can be immediately recognized, thereby reducing maintenance time and reducing costs.

Apparently, there are many different ways to modify these embodiments while remaining within the scope of the claims. In other words, there may be many other ways in which the invention may be practiced without departing from the scope of the following claims.
