Generally, a power management system (PMS) automatically programs power control in large residential complexes, factories, industrial complexes and buildings, and smooths power supply through automatic measurement and secures safety against power demand This system mainly controls and maintains the electric power distribution equipment, and can centrally monitor the fire fighting, communication, and other air conditioning facilities, so that all power control related to interlocking, starting, and stopping of various facilities is collectively handled .

Currently, electrical energy consumption is increasing globally, but investment in new power transmission and power distribution networks and / or energy generation capabilities is becoming increasingly difficult.

This may be due to factors that include increased environmental loads in the form of carbon dioxide emissions or not to invest in rapidly changing energy markets.

Conventional power management systems have not only been able to virtually identify the state of the power supply being re-supplied upon completion of maintenance through maintenance or replacement of power lines or automation switches. It took a long time to understand the power supply status.

In addition, although the conventional load control system requires fast / accurate load control processing in an unstable power supply / demand situation, it is difficult to reduce the information providing range and to focus on the experience of the operator (or manager) in an emergency situation. And it was difficult to judge the situation and the influence of the spread.

In addition, since the conventional power distribution system is based on a circuit diagram, it is difficult to precisely locate the power failure area due to load control.

In order to solve this problem, a registered patent described in the above prior art document has been disclosed.

However, in the registered patent, there is only a system for controlling the load, and there is no means for quickly recovering and recovering an abnormality at a specific point in the distribution line.

The power distribution system management unit 200 includes a plurality of power distribution lines recognized from the power distribution system information, And the distribution network is implemented as a two-dimensional map (Map) or a three-dimensional map (Map).

The power distribution system management unit 200 calculates a power loss damage influence analysis value and a load amount for a plurality of distribution lines and a plurality of automation switches provided on the power distribution network to calculate a load control target line and a load control target switch At least one of them is selected.

The power loss damage influence analysis result is a result obtained by collectively judging the effect of the electrostatic damage damage given to each customer type and the case of the previous power failure damage, and the load is a value obtained by dividing the power demand from the external power supply source If the value is not available, it is the average value of the power actually consumed in the year / month / day of the power line.

In other words, the power distribution system management unit 200 is configured to detect the power loss damage affecting line and the loads on the basis of the load distribution, and to provide a plurality of power distribution lines and a plurality of automation switches, And at least one load control target switch.

As a selection criterion to select the load control target, first, the load control target is set to the distribution line set in the distribution line for the control lines, and the load information of the automation switch is compared with each other. If the load information of the switch is equal to or larger than the target value Are extracted on a line-by-line basis.

All lines should be arranged in order of influence. If the control method is a switch, the influence of the switch selected above is applied. If the power loss damage degree score is summed in order of load from the line with the lower score and is smaller than the total load control target value (kW) of the substation, the corresponding line or switch will be selected as the load control target.

The biggest factor to be selected as the load control target would be the time when the power loss impact of the load customer included in the selected distribution line and the automatic switch is the lowest.

In addition, the power distribution system management unit 200 may transmit the automatically generated load control target power failure information through an SMS (Short Message Service) method or an MMS (Multimedia Message Service) And notifies the terminal 300.

Here, the pre-outage information of the load control target includes the coordinates of the corresponding distribution line and the corresponding automatic switch selected as the load control target, and the location of the facility, and it is necessary to block the demanded power in advance in the case of repair or replacement work It is important to note that this is information to inform in advance the power-off timing (specific date and time) in advance.

The DAS linkage unit 500 obtains the open / close status information of a plurality of automatic switches that are automatically recognized from the connected Distributed on Automation System (DAS) and transmits the open / close status information to the database unit 100. At this time, the open / close status information is signal information for confirming whether or not the automatic switch is operated. For example, the open / close status information is open when a power failure occurs due to disconnection or the like, and is closed when the power switch is normally maintained.

Such an automatic switch is generally regarded as a S-Load Break Switch for distribution automation. Usually, when a power failure occurs in a power system, the fault section is separated by remote or manual operation, and power is supplied from the non- It is a device used to shorten the time.

The present invention prevents the deterioration of the database unit 100, the power distribution system management unit 200, the remote meter reading connector 400, and the DAS coupling unit 500 mounted on the load control unit 1000, An indirect cooling structure for cooling the cooling water is further included in a characteristic configuration.

This is because the database unit 100, the power distribution system management unit 200, the remote meter connection unit 400 and the DAS connection unit 500 constituting the load control unit 1000 are mounted in the form of boards or modules, The main components constituting each of them due to the heat released during the operation are deteriorated to shorten the service life. Therefore, a structure for preventing such deterioration is a main feature of the additional embodiment of the present invention.

The load control unit 1000 includes a housing 2130 as illustrated in FIG. 3, and a plurality of devices such as a database unit 100 and a distribution system management unit 200, a remote meter reading connector 400, a DAS connector 500, and the like.

In this case, the database unit 100, the power distribution system management unit 200, the remote meter reading connector unit 400, the DAS connector unit 500, and the like are usually mounted on a thick plate or a rack And the like.

Therefore, in the further embodiment according to the present invention, the indirect cooling structure is not applied to the thick plate 2136 and the bottom plate 2140 constituting the housing 2130.

More specifically, the housing 2130 includes a rectangular frame 2132 and a front door 2134 is hingedly fixed to one side of the stationary frame 2132 so as to be openable and closable on the front surface of the stationary frame 2132 A rear plate 2136 is fixed to the rear surface of the front frame 2134 opposite to the front door 2134 and a side plate 2138 is fixed to both sides of the fixing frame 2132. A bottom plate And an upper plate 2142 is fixed to a ceiling facing the bottom plate 2140. [

In addition, air suction holes 2138a in the form of a rectangular slit are formed in both side plates 2138, and a filter 2138b is incorporated in the air suction holes 2138a.

Therefore, the outside air is introduced into the housing 2130 in a filtered state.

Meanwhile, an indirect cooling unit 2150 is installed on the upper surface of the upper plate 2142.

7, the indirect cooling unit 2150 includes a rectangular box-shaped suction chamber 2152 opened to communicate with the housing 2130 via the upper plate 2142, A blowing pipe 2154 penetrating through the center of the top surface of the suction chamber 2152 and having a hooked lower end inserted and fixed therein, a blowing fan 2156 installed at the upper end of the blowing pipe 2154, An exhaust hole 2160 formed in the horizontal portion 2158 and a plurality of exhaust ports 2162 formed in the upper surface of the suction chamber 2152 on a position equivalent to the exhaust hole 2160.

Therefore, when the blowing fan 2156 is operated, the outside air is introduced and discharged into the blowing pipe 2154, and then discharged through the discharge hole 2160 and the discharge port 2162.

That is, the introduced outside air is not supplied into the housing 2130 but is diverted and then discharged to the outside.

In the process, negative pressure is generated in the interior of the suction chamber 2152, particularly around the discharge port 2162, and the internal air distributed in the lower space of the suction chamber 2152 due to a kind of venturi effect due to the suction pressure by the negative pressure So that the heated air inside the housing 2130 is sucked to the outside.

As a result, the inside of the housing 2130 is entirely formed with negative pressure, fresh cool external air is introduced into the housing 2130 through the suction hole 2138a via the filter 2138b, dust is generated in the housing 2130 It is naturally cooled to a non-scattered state.

That is, since the general cooling structure is a structure in which outside air is introduced through the air blowing fan 2156 and is directly injected into the housing 2130 to be cooled directly, severe dust is generated inside the housing 2130 due to wind pressure , The dust is attached to the main terminals of each board, and in some cases, a spark due to static electricity is generated, which may cause a short circuit.

However, since the present invention has an indirect blowing mode in which such a situation is completely dispensed, that is, an indirect cooling structure, cooling can be performed without generating dust inside the housing 2130.

The inner surface of the front door 2134, the side plate 2138, the bottom plate 2140 and the thick plate 2136 constituting the housing 2130 is formed with a heat-resistant coating layer and a latent heat-resistant coating layer. If the latent heat function, that is, the heat retaining function, which expels the heat in the cold state, is provided, it is possible to operate more stably and thus deterioration of the board can be suppressed as much as possible. In addition, it is more preferable to provide an anti-static function so as to contribute to stabilization to prevent a short circuit.

The coating layer for this purpose was prepared by mixing 8 parts by weight of sodium silicate, 2.5 parts by weight of oxycarboxylate, 1 part by weight of citronella ) Oil, 1.5 parts by weight of microencapsulated polypropylene yarn of 0.1 탆 length, 3 parts by weight of paraffin wax, 4 parts by weight of polyoxyethylene, 3 parts by weight of propylene glycol, 2.5 parts by weight of N-ethylgavazol methacrylate , 3 parts by weight of sepiolite, 2.5 parts by weight of melamine cyanate, 2.5 parts by weight of tetraisopropyltitanate, and 1.5 parts by weight of mica, and spray-coated at 50-60 占 폚.

Here, the reason why the mixture is heated to the above-mentioned temperature range is to maintain uniform dispersibility and stability while increasing fluidity, wherein the acrylic resin is to maximize the adhesive force, and the methylpentene polymer resin has low viscosity and fluidity It is easy to apply and is added especially to have a very high melting point of 235 ° C, to have excellent mechanical strength at high temperature and to enhance heat resistance stability.

In addition, the sodium silicates are added to enhance the heat stability by inducing gelation to form a film.

In addition, the oxycarboxylate is added to reduce moisture content of the material to reduce voids and thereby increase strength.

The citronella oil is generally added to improve the insect repellency, but in the present invention, it is added in order to promote the viscosity control and the coordination of the inorganic powders.

In addition, a polypropylene yarn having a length of 0.1 mu m and microencapsulated by a Wurster Method can be further added so that heat resistance can be realized in the urethane resin.

The paraffin wax is a phase change material having a phase change temperature range of 20 to 50 ° C. The paraffin wax is a phase change material which accumulates latent heat during heating to prevent the temperature from being deprived, thereby performing a heat holding function for a long time, So that it is added in the present invention for latent heat utilization.

Polyoxyethylene is a kind of polyether which is obtained by polymerization of ethylene oxide with a cationic catalyst. In the present invention, it is added in order to inhibit the generation of static electricity by forming a film in a state of being dissolved in water in a fabric and paper.

In addition, propylene glycol is hygroscopic but has no volatility and is stable to heat and light, so it is used as a solvent to dissolve resin and mix with water, and is added to prevent fungal growth on the surface.

In addition, N-ethyl-carbazole methacrylate is added to prevent cracking by inducing stabilization of the coating layer while enhancing transparency.

Furthermore, sepiolite is referred to as meerschaum, a round tubular variant, and is added to induce dispersion stability and uniform dispersion of the resin composition.

According to the structure of the coating layer, it is possible to contribute to prevention of deterioration of the board using heat resistance and latent heat characteristics.

In order to confirm whether or not the coating layer has latent heat characteristics, that is, heat retainability, a steel plate sample having no coating layer and a steel plate sample having a coating layer were prepared, and heat radiation side was confirmed according to JIS C 6802-1997.

As a result of the measurement, it was confirmed that there was a latent heat characteristic (heat absorption power) when the coating layer was present at 46 W / m.k when there was a coating layer and 58 W / m.k when there was no coating layer.

Further, as shown in FIG. 5, a plurality of radiating fins 2170 are further formed to pass through the inner surface of the front door 2134 and the side plate 2138 in order to further enhance the heat radiation characteristics.

That is, the radiating fin 2170 is first formed, and the coating liquid is sprayed to form a coating layer.

In this case, the natural cooling efficiency can be enhanced through the thermally conductive rod 2176 made of copper, which has a very good thermal conductivity, so that more effective heat dissipation is possible, which can contribute to prevention of deterioration of the mounted product.

In addition, the housing 2130 may be attached to the sound absorbing sheet 2180 along the inner side surface of the side plate 2138, as shown in FIG. 6, to reduce noise generated during operation of the devices mounted therein.

The sound absorbing sheet 2180 is in the form of a gasket and is mounted on the coating layer and along the circumference of the side where the heat radiation fins 2170 are not formed so as not to interfere with the heat radiation fins 2170.

Particularly, the sound absorbing sheet 2180 is not a known non-woven fabric but uses a circular knitted fabric to significantly increase sound absorption and sound insulation effects.

That is, when the yarn is circularly wound through the circular knitting machine, a substantially cylindrical fabric is formed. The material of the fabric is polypropylene yarn, and at least a, b, c, , and c two knitting yarns are knitted into a general fabric, and b and d two knitting yarns are knitted into a denser elastic structure so that the circularly formed polypropylene knitted fabric 2182 is repeatedly formed in a longitudinal direction and compacted, So that the sound absorbing characteristic is improved by making the sound absorbed, i.e., sounding, completely obstructed.

In addition, in order to improve sound absorption characteristics and adhesion properties, the cylindrical polypropylene knitted fabric 2182 is flattened in a radial direction to form a double layer, and the outer surface, that is, the periphery of the double- So that the sound absorbing sheet 2180 according to the present invention can be realized.

In this case, since the cylindrical polypropylene knitted fabric 2182 can not be inflated in a pressed state, it is possible to safely hold the sheet image. In particular, the PET film 2184 is needle-punched for forming voids, Structure.

Then, the generated noise is introduced into the polypropylene knitted fabric 2182 through the needle hole of the PET film 2184, is completely confined, is refracted and reflected inside, loses energy, and is completely cased, and the sound is lost. .

On the other hand, the present invention further includes a recovery vehicle (RU) capable of moving to a point where a damaged power line is damaged when a power failure occurs.

In this case, the generation of the blackout may be caused by various causes. In particular, the recovery vehicle (RU) according to the present invention includes a case where the power distribution line is disconnected due to various causes such as lightning, This is for quick recovery.

In this case, the fault point confirms the position (number is assigned) of the automatic switch at the point of failure through the opening / closing status information of the automatic switch, quickly moves to the corresponding point, And the related information is restored by the operator carrying the recovery vehicle RU carrying the communication terminal 300 and receiving the information through the communication terminal 300. [

Of course, the communication terminal 300 may also be mounted on the recovery vehicle RU.

The recovery vehicle RU includes the moving vehicle main body 10 shown in Fig.

In particular, the cab 20 is provided with a controller (not shown), and the operation of the various hydraulic circuits, motors, cylinders, heaters, switches, and the like to be described later is controlled by the operation of the controller.

However, the controller is preferably a PLC which is mostly used as a controller in various industrial machines.

In addition, a hydraulic tank 30 is provided on a part of the upper surface of the moving vehicle body 10 to adjust the hydraulic pressure relationship, which is a concept similar to a well-known excavator and is a known part not constituting technical features of the present invention A description of this portion will be omitted.

In addition, the moving vehicle body 10 is constructed so that the wheels 40 can be installed on both sides of the lower surface thereof.

A pair of fingers 50 is provided on the rear side of the moving vehicle body 10, that is, on the opposite side of the cab 20.

The lower end of the side portion 52 is linked on the first and second brackets 62 and 64 in the H shape and the upper end of the side portion 52 is connected to the first and second brackets 62 and 64. [ And is fixed to the main cylinder rod 68, and the rectangular side wall 70 is firmly fixed to the rear side portion 54.

The first and second brackets 62 and 64 are protrudingly fixed to both sides of the upper surface of the moving vehicle body 10 and the lower end of the front side portion 52 of the bracket 50 is fixed to the second bracket 64 And the main cylinder rod 68 is connected to the main cylinder 66. The lower end of the main cylinder 66 is rotatably linked to the first bracket 62. [

Accordingly, as the main cylinder 66 is operated and the main cylinder rod 68 is pulled out, the fascia 50 can be folded and unfolded.

In particular, a height adjusting cylinder 72 is further provided on the outer circumferential surface of the rectangular fixing cylinder 70, and a height adjusting rod 74 is connected to the height adjusting cylinder 72, Is coupled to the sliding bar (80) through the binding opening (76).

Therefore, when the height adjusting cylinder 72 is operated to raise the height adjusting rod 74, the sliding bar 80 is pulled out and raised together.

A cutting cylinder 82 is installed on the inner side of the pair of sliding bars 80 facing each other and a cutting motor 86 is fixed to the cutting rod 84 of the cutting cylinder 82 , And a circular rotary cutter (88) is fixed to the rotary shaft of the cutting motor (86).

Therefore, when the cutting cylinder 82 is operated and the cutting rod 84 is pulled out while the rotary cutter 88 is rotating, the rotary cutter 88 can be moved so that a specific point of the power distribution line can be cut have.

A clamping means 90 is provided on the surface of the sliding bar 80 opposite to the cutting cylinder 82.

8, the clamping means 90 holds the power distribution line L in a state of holding the power distribution line L with the disconnected point of the power distribution line L therebetween, and in this state, the rotary cutter 88 cuts the inside . In other words, even after the power distribution line L is cut, the power distribution line L is held by the clamping means 90 as it is.

The clamping means 90 includes a clamp cylinder 92 fixed to a side surface of the sliding bar 80, a clamping rod 94 connected to the clamp cylinder 92 to be drawn in and out, And a scissors clamp 96 for grasping or grasping the grasped grip 96 by means of the grasping and pulling-out.

Particularly, a portion of the inner circumferential surface of the scissors-type clamp 96 is manufactured by insert-molding the metal conductor MT into the synthetic resin so that it can be energized if the cover is peeled off when the distribution line L is engaged, The first and second conductive lines SLR1 and SLR2 shown in FIG. 9 are connected to the switching unit MT and are then passed through the sliding bar 80 and the rectangular fixing unit 70, And is connected to the switch SW after passing through the span SP. The switch SW is configured to control the on / off control of the controller of the cab 20 described above.

In this case, a heater HT is built in a part of the plate surface of the metal conductor MT, that is, a part of the inner circumferential surface of the scissors clamp 96 so that the coating of the power distribution line L can be peeled off, and the heat generation is controlled by the controller.

In this state, the metal conductor MT completely covers the distribution line L in a state in which the cover of the distribution line L is melted and then completely fused and fixed by the scissors-type clamp 96, so that the metal conductor MT completely contacts the circumferential surface of the distribution line L So that it is possible to eliminate the problem that heat may be generated due to an increase in resistance when locally brought into contact by using a needle or the like.

In addition, it is preferable that the clamp rod 94 and the clamp cylinder 92 except for the scissors-type clamp 96 are coated with an insulating material so as to increase the insulating property.

As the insulating material to be applied, 4 parts by weight of tragacanthate, 5 parts by weight of wollastonite powder, 1 part by weight of alumina, 3 parts by weight of silica and 5 parts by weight of EPR (ethylene propylene rubber) were added to 100 parts by weight of urethane resin , And it is used to have insulating property by applying it to a certain thickness.

In this case, the tragacantha is added as a kind of rubber component for viscosity control, and wollastonite is low in hygroscopicity, and since it has no crystal number, it has excellent dimensional stability and induces thickness stabilization after coating, and alumina, silica and EPR are typical insulating materials .

Thus, after receiving the disconnected point through the communication terminal 300, the moving vehicle body 10 is moved, and the heater HT is fixed with the scissors-type clamp 96 firmly fixed on both sides of the disconnected point, To dissolve the coating.

Then, when the switch SW is turned on under the control of the controller, energization is possible with the switch SW therebetween. As a result, power is supplied and the temporary restoration is completed.

In this state, by raising the rotary cutter 88 to cut off the right and left sides of the broken line and removing the clamping means 90 after the emergency repair, it is possible to quickly recover and minimize the damage.
