Description

Distribution Line Protection Panel for Underground Line

More particularly, the present invention relates to a protection panel for underground electric wires, and more particularly, to a monitoring panel that detects a monitoring information including an abnormality of an underground cable installed in an underground pipe embedded in an underground pipe and a vibration condition of an underground pipe, In addition, it is possible to grasp the position of the underground wire where the abnormality occurred among the multiple underground wires, to perform maintenance, and to configure the shelf equipped with the underground wire to move upward, so that occurrence of safety accidents due to electric shock can be suppressed And to a protection panel with a distribution line of the underground electric wire.

In general, electric power lines are installed in electric poles or buried in the ground in order to supply electric power. The ground and airborne type are much more economical than the method of buried in the ground in consideration of the workability, the construction cost and the construction period Although there is an advantage that construction can be simplified, it is disadvantageous that it is difficult to install in a place where buildings are very close to each other, such as a downtown area.

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.

The electricity distributed from the primary substation or the secondary substation is transmitted or distributed to the reception facilities of each customer through the transmission and distribution system composed of the processing distribution line and the underground distribution line. The electricity is distributed to the customer through the special high pressure customer, the high pressure customer and various outdoor installation transformers. It is used for industrial and domestic purposes.

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.

1 and 2, the underground pipe 10 is formed in the form of a rectangular box having an internal space that an operator can enter and maintain. For example, the underground pipe 10 may be manufactured to have a length and a length of about 2 m each.

A base 20 having a predetermined width and height is provided on the bottom surface of the receiving space 11 for receiving the underground cable of the underground pipe 10. A support 21 is installed vertically at the center of the base 20 And a control unit 50 in the form of a box is installed on one side of the support 21. The control unit 50 and the support 21 are installed so as to be connected to each other.

A plurality of unit ground wires (L) L1 and L2 ... L8 are arranged on the upper surface of each shelf 30 in a predetermined interval and a width Respectively. According to the present invention, the underground wires L are arranged so as to be spaced apart from each other and are seated in a seating groove 301 formed in the longitudinal direction on the upper surface of each shelf 30.

The ground wire L described above can be arranged so that the flow thereof is interrupted when it is seated on the shelf 30. 1, the seating groove 301 formed in the shelf 30 is formed so as to be deeper than the radius R of the applied unit ground wire L so that when the ground wire L is seated in the seating groove 301, the ground wire L So that at least one half of the outer circumferential surface of the mounting recess 301 can be seated.

Accordingly, when the ground wire L is placed in the seating groove 301, the worker applies a constant force in the direction of the seating groove 301 to fix the ground wire L to the seating groove 301 in a forced fit manner.

On the other hand, a sensing panel 40 is mounted on the lower side of each shelf 30 described above. A plurality of sensors are disposed on the surface of the sensing panel in contact with the shelf 30 at positions corresponding to the seating grooves 301 formed in the longitudinal direction of the shelf 30. [ The above-described sensor is preferably a photosensor S, and the photosensor S preferably has a general configuration in which a light-emitting portion (light-emitting portion) and a light-receiving portion are provided together. The optical signal output from the light emitting portion of the photo sensor S is reflected on the surface of the object or the ground wire L and is received by the light receiving portion. That is, the case where the light receiving unit of the photo sensor S does not receive the optical signal output by the light emitting unit.

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

Therefore, it is preferable that the shelf 30 is made of a transparent synthetic resin, or at least only the portion where the photosensor S is disposed is made of a transparent material. Or if the shelf is formed of a metal material, the corresponding position of the photosensor S described above may be formed as an open hole.

The control unit 50 is fixed on the upper side of the highest part of the underground pipe 10 in order to preempt the safest position when the underground pipe is submerged. The control unit 50 is electrically connected to the sensing panel 40 provided in correspondence with each shelf 30 and is connected to the underground pipe 10, the shelf 30, It is possible to read information on the abnormality of the underground wire L and to transmit the information to the ground operator wirelessly.

Referring to Fig. 3, the support 21 has a hollow portion 211 in the form of a pipe. The electrical lines of the sensing panel 40 fixed to the support 21 are connected to the control unit 50 through the hollow portion 211 of the support 21. That is, the complication of the external wirings is eliminated and the malfunction of the control unit due to flooding is prevented in advance.

Accordingly, in the case of a specific ground wire position deviation that may occur due to a natural disaster such as earthquake, ground erosion or the like, and the position of the shelf 30 is changed, the photosensor S disposed at the lower side performs a sensing operation, 50, and the control unit 50 can transmit the abnormal information of the underground cable L to the ground operator.

[

The abnormal position confirming unit 52 receives the sensing signal of the corresponding underground wire L in which the abnormality occurs among the plurality of photosensors S arranged on the sensing panel 40 and outputs the position information of the corresponding shelf 30 And provides information of the underground pipe 10 to the control unit 51.

For example, when the ground wire L is detached from the seating groove 301 of the shelf 30, the photosensor S of the sensing panel 40 senses it and provides it to the abnormal position determination unit 52. The sensing information may be a concept including positional information of the unit underground wire L and positional information of the corresponding shelf 30 and unique information of the underground pipe 10. Therefore, the abnormal position confirming unit 52 detects the sensing signal, and provides information on the underground pipe 10, information on the shelf 30, and information on the underground wire L to the controller 51.

The control unit 51 transmits the abnormal information about the underground wire L provided by the abnormal position confirmation unit 52 by using the wireless transmission unit 53. [ The control unit reads the detection signal of the underground cable L provided by the abnormal position confirming unit 52 and transmits the position of the underground wire L, the corresponding position of the shelf 30 and the information of the specific underground pipe 10 accordingly, It is possible to convert the signal into a signal that can be read and send the signal by controlling the radio transmission unit 53.

More preferably, the control unit described above may be a concept including a storage unit. Therefore, it is also possible to provide the information of the underground cable detected by the abnormality by providing the operator with the storage information of various additional information such as the role and function of the underground cable.

For example, when the sixth underground cable L6 of the second shelf R2 of FIG. 1 is detached from the shelf, the corresponding photosensor S of the detection panel installed below the shelf detects that the underground wire is detached. For example, the photo sensor of the sensing panel may include a light emitting portion and a light receiving portion. When a ground wire is placed on a transparent material shelf, the light source irradiated by the light emitting portion is reflected by the underground wire and is received by the light receiving portion, It will detect that it is not detached from the seating groove.

However, when the underground wire L is detached from the seating groove 301, the light receiving unit which is irradiated by the light emitting unit and received the light source reflected by the underground wire can not receive the light source reflected by the deviation of the underground wire, To the abnormal position confirming unit (52) of the control unit (50).

Accordingly, the abnormal position confirming unit 52 confirms the detected position information of the photosensor S and provides the controller 51 with information on the detected position information. The control unit transmits the information provided (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 area) via the wireless transmitter 53 .

Therefore, an operator working on the ground immediately monitors such monitoring information and determines the position of the underground pipe 10 and the type of the underground wire R2 (where the underground wire L6 is located) The extra high voltage wire), which can shorten the maintenance time and reduce the cost.
