Recognizing that there is always a risk of power supply interruption due to a failure anywhere in a vast distribution line, we will minimize the range of power supply interruption in case of a failure or minimize the time the power supply is interrupted. The point of failure should be determined quickly and accurately, and measures should be taken so that power can continue to be supplied to parts other than the part where the failure occurred.

To this end, in the prior art, when a fault current occurs in a distribution line, the operator and substation manager in the field operate the substation breaker to find the fault point where the fault current occurs, and the operator and substation manager mainly use communication means to provide information about the accident point. Finding fault points by exchanging them was a common method.

However, in the case of the above method, a lot of time and manpower is consumed, and the failure time increases as the recovery time increases, which causes great inconvenience to power consumers.

Of course, the distribution station, which automatically and comprehensively monitors electric power facilities to minimize power outages and recover from failures quickly, has sufficient and complete protection against fire, and displays an evacuation route even in the dark in case of fire to induce rapid evacuation of the occupants. Its main purpose is to provide a method for providing a fault recovery system for an underground distribution line connected to an improved substation to prevent human casualties through

In addition, it relates to a method of providing a stable system in advance by managing the initial preparation process, such as handling problems, procedure violations, errors such as combined installation, etc.

Hereinafter, a preferred embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

1 to 4, the method for providing a system for repairing a failure of an underground distribution line connected to a substation according to the present invention is a distribution information acquisition unit 120 installed in the substation 110, a shear processor 130, It includes a distribution control unit 140 and a distribution station 150 .

The distribution information acquisition unit 120 is installed in each substation 110 to acquire status information and fault recovery information of the substation 110 when a failure occurs in the substation 110 . The distribution information acquisition unit 120 acquires state information including the power usage and peak capacity of all facilities in the substation 110 just before the occurrence of a failure of the substation 110 .

In this case, the power usage is the actual power usage capacity of the facilities, and the peak capacity refers to the maximum power usage capacity of the facilities.

The distribution information acquisition unit 120 includes a recovery participation capacity that combines the power consumption and peak capacity of the healthy substation 110 facilities participating in the failure recovery and the capacitance according to the occurrence of a failure in the substation 110, and distribution provided in the substation 110. The fault recovery information including the load capacity of the feeders and the load capacity of the peripheral voltages (MTR) provided in the substation 110 is acquired.

At this time, the capacitance is the capacity generated by the fixed equipment when the substation 110 failure occurs, and the recovery participation capacity is the individual used capacity of all sound facilities that can participate in the failure recovery with respect to the used capacity of the malfunctioning equipment when the substation 110 failure occurs. It refers to the total capacity of all peak capacity except for the peak capacity.

The distribution information acquisition unit 120 determines the failure type through the state information obtained as described above, and determines whether failure recovery is possible inside the substation 110 through the failure recovery information, and determines that the failure recovery is impossible inside. If possible, extract the final electrostatic feeder.

To this end, the distribution information acquisition unit includes a failure mode determination unit 121 , a failure recovery determination unit 123 , and a final power outage feeder extraction unit 125 as shown in FIG. 2 .

The failure mode determination unit 121 determines whether a failure occurring in the substation 110 is a failure related to a peripheral voltage or a power trunk (BUS) or a distribution feeder through the state information. The reason for determining this is that all other blackout accidents other than this are accidents that can be handled inside the substation 110 .

The failure recovery determination unit 123 compares the lowest minimum load capacity among the electrostatic capacity, the recovery participation capacity, and the load capacity of the distribution feeders, respectively, and determines whether the failure is repaired inside the substation 110 .

That is, the failure recovery determination unit 123 compares the capacitance and the recovery participation capacity, and if the recovery participation capacity is smaller than the capacitance, it is determined that the failure recovery is impossible inside the substation 110, and the capacitance and the distribution feeder When the minimum load capacity is compared and the minimum load capacity of the distribution feeder is smaller than the electrostatic capacity, it is determined that failure recovery is impossible inside the substation 110 .

In this case, when the minimum load capacity of the distribution feeder is greater than the capacitance, the failure recovery of the substation 110 is possible without powering off the corresponding distribution feeder. The final electrostatic feeder extraction unit 125 extracts the final electrostatic feeder when it is determined that failure recovery is impossible inside the substation 110 .

To this end, the final electrostatic feeder extraction unit 125 includes an electrostatic feeder existence confirmation unit 126, a first comparison unit 127, a second comparison unit 128, and a final electrostatic feeder selection unit ( 129).

The electrostatic feeder existence check unit 126 checks whether an electrostatic feeder exists in two or more of the peripheral voltages in the substation 110 .

When an electrostatic feeder exists in two or more peripheral voltages, the first comparator 127 sorts the restoration participation capacity of the healthy peripheral voltages participating in the restoration from the minimum to the maximum in order of the capacitance and sequentially. compare with

That is, the first comparison unit 127 compares the recovery participation capacity of the peripheral voltages arranged in order of magnitude until they have a value greater than or equal to the capacitance.

When an electrostatic feeder exists in one peripheral voltage, or when the recovery participation capacity of the peripheral voltages is greater than or equal to the capacitance as a result of the comparison, the second comparator 128 performs a distribution feeder in the corresponding peripheral voltage. Sort their load capacities in the order from minimum to maximum and sequentially compare them with the final capacitance.

That is, the second comparison unit 128 compares the load capacities of the distribution feeders arranged in order of magnitude until they have a value greater than or equal to the final capacitance. In this case, the final capacitance refers to the capacitance that has been offset by the recovery participation capacity of the healthy facilities participating to restore the capacitance generated when the substation 110 fails.

The final electrostatic feeder selector 129 selects a corresponding distribution feeder as the final electrostatic feeder when the load capacity of the distribution feeder is greater than or equal to the capacitance as a result of comparison. The shear processor 130 collects the state information and fault recovery information of the substation 110 obtained from the distribution information acquisition unit 120 , and information on the final power outage feeder, and transmits it to the distribution control unit 140 .

The distribution control unit 140 determines whether the normally open point connection of the distribution line or the normal connection point is disconnected based on the extracted final power outage feeder, so that the failure recovery of the substation 110 is performed.

To this end, the distribution control unit 140 includes an open point connection determination unit 141, a connection point separation determination unit 142, a load distribution determination unit 143, and a load redistribution determination unit 144 as shown in FIG. do. The open point connection determining unit 141 determines whether the final electrostatic feeder can be restored through the regular open point connection.

That is, the open point connection determining unit 141 determines whether the final electrostatic feeder is restored by connecting the normally open points, which are commonly referred to as circuit breakers and switchgear, which are always open in the distribution line. At this time, if the recovery of the final power failure feeder is possible through the normal open point connection, the failure recovery is completed.

The connection point separation determining unit 142 determines whether the final electrostatic feeder can be restored through the normal connection point separation when it is determined that the final electrostatic feeder recovery is impossible due to the normal open point connection.

That is, the connection point separation determining unit 142 determines whether the final electrostatic feeder is restored by separating the normal connection points, which are commonly referred to as circuit breakers and switchgear, which are always off in the distribution line. At this time, if recovery of the final power outage feeder is possible by disconnecting the connection point at all times, the fault recovery is completed by determining the load distribution for redistribution of the load on the distribution line. .

The load distribution determining unit 143 determines the load distribution of the distribution line when it is determined that the final power failure feeder can be restored by disconnecting the connection point at all times. The load redistribution determining unit 144 determines whether to redistribute the distribution line load on the basis of the identified load distribution, and if redistribution is possible, fault recovery is completed, and if not, fault recovery is impossible.

In addition, the present invention may further include a power distribution station 150 for automatically and comprehensively monitoring power facilities for minimizing power outages and promptly recovering from failures. Thus, as shown in FIGS. 5 and 6 , when a failure occurs in the substation 110 , the state information and the failure recovery information of the substation 110 are acquired ( S100 ).

At this time, the state information is information including the power usage and peak capacity of the substation 110 facilities just before the failure of the substation 110 occurs. The breakdown recovery information includes the recovery participation capacity that combines the power consumption and peak capacity of the healthy substation 110 facilities participating in the failure recovery and the capacitance according to the occurrence of a failure in the substation 110, and a distribution feeder provided in the substation 110. It is information including the load capacity of the substation 110 and the load capacity of the peripheral voltage transformers (MTR) provided in the substation 110. Next, the failure type of the substation 110 is determined through the state information (S110).

That is, it is determined whether the failure occurring in the substation 110 is a failure related to the peripheral voltage or the power trunk (BUS) or the distribution feeder through the state information. This is because other blackout accidents other than this are accidents that can be handled inside the substation 110 . Next, it is determined whether failure recovery is possible inside the substation 110 through the failure recovery information.

First, by comparing the capacitance and the recovery participation capacity (S120), if the recovery participation capacity is larger than the capacitance, proceed to the next step (S121), and if it is small, the recovery is possible inside the substation 110. Failure recovery (S122) is completed.

Next, the capacitance and the lowest minimum load capacity among the load capacities of the distribution feeders are compared (S121). If the minimum load capacity is larger than the electrostatic capacity, proceed to the next step (S130), and if it is small, the substation 110 inside Since recovery is possible in the substation 110, the failure recovery (S122) is completed inside the substation 110.

Next, when it is determined that failure recovery is impossible inside the substation 110 , the final power outage feeder is extracted.

First, it is checked whether an electrostatic feeder exists in two or more of the peripheral voltages of the substation 110 (S130).

Next, when an electrostatic feeder is present in two or more peripheral voltages, the load capacities of the sound peripheral voltages are sorted from the minimum to the maximum (M) in order (S131) and sequentially compared with the capacitance (S132) do.

At this time, if the recovery participation capacity of the peripheral voltages is greater than or equal to the capacitance, the process proceeds to the next step (S133). By summing the recovery participation capacity, the current step (S132) is performed again.

Next, when an electrostatic feeder exists in one peripheral voltage or when the recovery participation capacity of the peripheral voltages is greater than or equal to the capacitance as a result of comparison, the load capacity of the distribution feeders in the corresponding peripheral voltage is increased from the minimum to the maximum. Sort them in order (F) (S133) and sequentially compare them with the final capacitance (S134).

At this time, if the distribution feeder load capacity of the corresponding peripheral voltage is greater than or equal to the final capacitance, the process proceeds to the next step (S140), otherwise, it returns to the previous step (S133) and the current distribution feeder load The current step ( S134 ) is performed again by adding the load capacity of the distribution feeder of the next order to the capacity.

Next, in the previous step (S131), the distribution feeder (feeder) is selected as the final electrostatic feeder finally blackout (S140). Next, based on the extracted final power outage feeder, it is determined whether the normally open point connection of the distribution line or the normal connection point is separated, so that the failure recovery of the substation 110 is performed.

First, it is determined whether the final electrostatic feeder can be restored through the normal open point connection (S141). At this time, if recovery is possible through the normal open point connection, the failure recovery is completed (S260), and if recovery is not possible, the process proceeds to the next step (S142).

Next, if it is determined that it is impossible to recover the final electrostatic feeder through the normal open point connection, it is determined whether the final electrostatic feeder can be recovered through the normal connection point separation ( S142 ).

At this time, if recovery is possible through the disconnection of the connection point, the load distribution of the distribution line is identified (S143), and the distribution line load is redistributed (S144) to complete the failure recovery (S160). If recovery is not possible, the failure recovery is impossible to complete (S150).

In addition, the power distribution station 150 is a facility that automatically and comprehensively monitors power facilities for minimizing power outages and promptly recovering from failures, and as shown in the example of FIG. include Since the control box 152 is an important control unit performing a control function, it must always be protected from fire.

To this end, in the present invention, as shown in the example of FIG. 8 , a fire fighting tank 200 built into the ceiling of the space where the distribution station 150 is installed, and a drum housing fixed to the ceiling surface directly above the front end of the distribution station 150 ( 300) is included.

At this time, the fire extinguishing tank 200 is filled with fire extinguishing liquid, and the fire extinguishing liquid is a liquid fire extinguishing agent used in a fire extinguisher having non-combustible properties, not general fire extinguishing water. In addition, the drum 310 is rotatably assembled inside the drum housing 300 . In addition, a drum motor 320 for rotating the drum 310 is fixed to one end of the drum housing 300 .

In addition, the drum 310 is configured to be wound or unwound with a fire plate 330. The fire plate 330 is a relatively thin and lightweight known fire plate, and both ends of the fire plates 330 have hinge links ( 340 is connected so that the fire plates 330 can be folded.

This is to make it easier to wind on the drum 310 . In addition, an injection pipe 350 is built on the fire plate 330 , and an injection hole 352 is formed in the injection pipe 350 , and fire extinguishing liquid is discharged through the hole formed to correspond to the front surface of the fire plate 330 . It is configured to be sprayed. To this end, the injection pipes 350 are connected to the flexible hose 360 and configured to receive a fire extinguishing liquid, and the flexible hose 360 penetrates the fire plate 330 up and down to penetrate the inside of the drum 310 . through the rotary joint 370 formed at the other end.

Then, the supply hose 380 extending from the fire fighting tank 200 through the rotary joint 370 is connected to the flexible hose 360 and connected to each other.

At this time, a part of the supply hose 380 is provided with a supply pump 390 , the supply pump 390 and the drum motor 320 are electrically connected to the controller 400 , and the controller 400 is a power distribution unit. It is electrically connected to the control unit 140 and is configured to drive and control them by quick control and control signals when a fire occurs.

Thus, when a fire occurs, the drum motor 320 is driven immediately and the fire plate 330 is spread out to cover the front of the power distribution station 150 in the form as shown in the figure to primarily block the spread of the flame.

Then, the supply pump 390 is driven according to the control signal, and since it is a well-known configuration, the valves not described are opened while the extinguishing fluid is supplied to the flexible hose 360 so that the extinguishing fluid is ignited through the injection hole 352 . The plate 330 is ejected forward to help extinguish the fire at an early stage.

In addition, in the present invention, as shown in the example of FIG. 9 , a pair of posts 500 are further installed at intervals from both sides of the distribution station 150 .

In addition, a fire extinguishing liquid sprayer 510 is installed at the upper end of the post 500 , a fire suppression pump 520 is built in one side of the inside of the post 500 , and the lower end of the post 500 is a fire extinguishing liquid tank 530 . ) is inserted and fixed on the fixing groove 532 with a concave indentation on the upper surface of the fire extinguishing liquid tank 530 is disposed on the bottom surface, and the inlet port 534 is provided on one side of the upper surface of the fire extinguishing liquid tank 530 . ), and the fire extinguishing liquid pipe 550 is piped through the stopper 534 so as to supply the fire extinguishing liquid inside the fire extinguishing liquid tank 530 to the fire extinguishing liquid sprayer 510 through the fire extinguishing pressure pump 520 .

In this case, the post 500 is further provided with a post controller 560 that receives a signal from the distribution control unit 140 and controls the operation of the fire suppression pump 520 . Accordingly, it is configured to minimize damage due to fire by double blocking and controlling the fire around the distribution station 150 when a fire occurs.

In addition, when a fire occurs, the interior may become dark as the lights are turned off. In this case, it may be difficult for the occupants to estimate the preparation route and a safety accident may occur in which they are trapped indoors. In order to solve this problem, in the present invention, since the fire plate 330 comes down as soon as the fire signal is received, the fire protection function is first performed before the electricity is cut off.

For this reason, it is useful in an emergency if an evacuation route display unit DSP as shown in FIG. 10 is displayed on the fire panel 330 .

The evacuation route indicator DSP is provided in such a way that a photoluminescent material is applied at a location avoiding the point where the extinguishing fluid is ejected. At this time, the photoluminescent material is not a general paint, but has been specially created and formulated by the present inventors so that it can be displayed for a long time with excellent photoluminescence properties while also having fire resistance. Therefore, the present invention also provides a method for manufacturing such a photoluminescent material.

The photoluminescent material according to the present invention includes a first step of crushing a strontium mineral to a particle size of 50 mm or less, and a second step of putting the crushed mineral in the first step into a heating and drying furnace and calcining with reduced heat at 800-1200° C. for 3 hours Step, a third step of pulverizing the reduced-calcined mineral through the second step with a nano grinder, and a fourth step of sieving and selecting only the particle size of 10 nm or less from the pulverized product pulverized through the third step; The prepared phosphorescent powder is used.

At this time, the reason for crushing the strontium mineral to a particle size of 50 mm or less in the first step is to increase the effect of calcination by heating loss. That is, it is more efficient to process small-volume objects than large-volume ones. In addition, the heating and drying furnace used in the second step is a rotary kiln, which is configured to be rotatably heated and fired with strong hot air.

This is to burn or volatilize impurities contained in strontium minerals, especially substances that inhibit afterglow luminance, while heating up to 1200°C, before completely dissolving into liquid phase, because strontium minerals are dissolved at 1300°C. Because.

In particular, since the hot wind is blowing, the impurity removal efficiency is very good. With respect to 100 parts by weight of the photoluminescent powder thus made, 3.5 parts by weight of waste glass powder having a particle size of 10 nm or less, 15 parts by weight of expanded graphite, 15 parts by weight of sodium hydroxide and 50 parts by weight of an epoxy resin were mixed and coated to form an evacuation route indicator (DSP). ) to form Here, the waste glass powder is to increase the afterglow brightness, and the expanded graphite, sodium hydroxide and epoxy resin increase the fire resistance.
