The present invention relates to a safety movable carbon neutral switchgear system capable of emergency response, and more particularly, to a safety movable carbon neutral switchboard system capable of emergency response capable of quickly maintaining power supply without interruption in the event of a switchboard failure. .

In the case of switchgear, it is often connected to receive power from the commercial power line (main power) and the spare power line from KEPCO. In this way, for the stable supply of power, two lines of power, commercial power and reserve power, are supplied and automatic load transfer switch (ALTS; also called “automatic transfer switch”) facility when the main power is outage or disconnected. The power is automatically switched by Automatic load switching switchgear is a device that automatically switches to standby power in case of main power outage.

In this way, when the ALTS is malfunctioning, the operator manually connected the bypass cable that bypasses the ALTS to respond, but this is a method that has several problems. First, since the operator must manually connect the bypass cable, there is a risk of human accidents such as electric shock. In addition, since it usually takes about 2 hours for an operator to directly install the bypass cable, there is a problem in that the power supply is interrupted for a long time. For example, when power is supplied to the water supply pump, the longer the stop time of the water supply pump is, the more air is filled in the empty pipe, and accordingly, there is a problem in that water is not smoothly supplied even when the water supply pump is restarted.

The present invention has been devised to solve the above-described problems, and has a structure capable of safely and quickly switching loads while preventing power supply interruption by supplying power through a bypass cable in the event of a failure of an automatic load switching switchgear. It aims to provide a safe movable carbon-neutral switchgear system capable of emergency response.

Hereinafter, with reference to the accompanying drawings, a safe movable type carbon neutral switchgear system capable of emergency response according to an embodiment of the present invention will be described.

1 is a block diagram of a safe movable type carbon neutral switchgear system capable of emergency response according to an embodiment of the present invention.

The safety movable carbon neutral switchgear system capable of responding to an emergency of the present invention supplies power to drive high-pressure/extra-high-pressure equipment such as a pump motor for water supply while operating general load equipment that operates other low-pressure equipment such as valves at the same time. It is intended to supply and monitor power at the same time.

Referring to FIG. 1 , the safe movable carbon neutral switchgear system capable of responding to an emergency of this embodiment includes an automatic load switch switch 600 , a first load switch 710 , a bypass cable 630 , and a second load switch 720 . ) and a bypass operation unit 730 .

The automatic load transfer switch (ALTS) (600, ALTS) is located at the beginning of the switchboard and transfers KEPCO's power to the facilities connected to the switchboard. The automatic load switching switch 600 serves to automatically switch the power supply to the reserve power when the main power is not supplied due to a power failure. Accordingly, the automatic load switching switch 600 is installed by being connected to the commercial power supply line 610 and the reserve power supply line 620 , respectively.

Load Breaking Switch (LBS) is a device that protects line branching, division, and power system by opening/closing no-load current in a 24kV power system. The safety movable carbon neutral switchgear system capable of responding to an emergency according to the present embodiment includes two load switchgears of a first load switchgear 710 and a second load switchgear 720 .

The first load switch 710 is installed between the load line connected to the load device and the automatic load switch switch 600 to open and close the power supply between the automatic load switch switch 600 and the load line. The load device refers to a configuration of various on/off valves including a water supply pump.

The bypass cable 630 bypasses the ALTS 600 and the first load switch 710 to connect the commercial power supply line 610 and the load line. The bypass cable 630 includes a commercial power supply line 610 and a load to supply power to the load line in an emergency, such as when power is not supplied to the first load switchgear 710 due to a failure of the ALTS 600 . It is a configuration that is installed to connect lines.

The second load switch 720 (LBS) is installed on the bypass cable 630 . Accordingly, the second load switch 720 serves to open and close the power supplied through the bypass cable 630 . Since the bypass cable 630 is a configuration used in an emergency, the second load switch 720 is normally maintained in an off state.

The bypass operation unit 730 is a device that operates the second load switch 720 . The bypass operation unit 730 mechanically operates by an electrical signal to turn the second load switch 720 on/off. The bypass operation unit 730 may be manually operated.

In this embodiment, the bypass operation unit 730 is configured to operate the first load switch 710 and the second load switch 720 by interlocking with each other. That is, the bypass operation unit 730 turns the first load switch 710 and the second load switch 720 on/off opposite to each other. When the first load switchgear 710 is on by the bypass operation unit 730, the second load switchgear 720 is turned off, and when the first load switchgear 710 is off, the second load switchgear ( 720) is turned on.

The bypass operation unit 730 may be configured in various forms. In the present embodiment, the bypass operation unit 730 is configured as shown in FIG. 2 .

The bypass operation unit 730 includes a solenoid 731 , a permanent magnet 732 , a slider 733 , and a guide rail 734 .

The solenoid 731 is configured to include a coil and is configured to generate a magnetic field by using electric energy by a current supplied to the coil. The permanent magnet 732 is disposed at a position adjacent to the solenoid 731 so that attractive and repulsive forces are applied by the magnetic field of the solenoid 731 .

The permanent magnet 732 is coupled to the slider 733 . The slider 733 is connected to the guide rail 734 to guide forward and backward sliding motion. Such a slider 733 is respectively connected to the first load switch 710 and the second load switch 720 . Accordingly, when power is supplied to the solenoid 731, the slider 733 moves along the guide rail 734 to turn the first load switch 710 into an off state and simultaneously turn the second load switch 720 to an on state. will make it Accordingly, when a failure occurs in the ALTS 600 and power cannot be supplied, power can be supplied to the load line through the bypass cable 630 . On the other hand, if the polarity of the power supply to the solenoid 731 is reversed, the slider 733 may be moved in reverse to turn the first load switch 710 into an on state and the second load switch 720 to an off state.

When a safety movable carbon neutral switchgear system capable of emergency response is configured to have such a bypass cable 630 and the bypass cable 630 is installed and operated as described above, the bypass operation unit 730 as described above, ALTS It is possible to effectively respond to an emergency such as a failure of 600. Since the operator does not need to manually install the bypass cable 630, safety problems such as electric shock do not occur. In addition, it takes at least 2 hours to manually install the bypass cable 630 in the related art, but 5 minutes when the bypass cable 630 and the bypass operation unit 730 are provided as in the present invention. Since it is possible to respond within a short period of time, it has the advantage of being able to prevent damage caused by power outage by rapid processing.

In particular, in the case of supplying power to a water pump installed at a high altitude, as the power recovery time elapses, the pipe is filled with air, which has the advantage of preventing the occurrence of a problem in which the water supply is not smooth even when the water pump is restarted. When the ALTS 600 fails, the power outage problem can be quickly solved within 5 minutes, so even at high altitudes, the possibility that the pipes are filled with air is low, and smooth water supply is possible by restarting the water pump.

As described above, the load line in which the power supply is guaranteed by the first load switch 710 and the second load switch 720 is connected to the pump motor control unit 850 . The pump motor control unit 850 receives power through a load line, supplies power to the pump motor, and controls the operation of the pump motor. The pump motor control unit 850 performs a function of a Motor Control Center (MCC).

The pump motor control unit 850 of this embodiment is configured to start the pump motor in an autotransformer starting method.

The starting method of a single winding transformer is a starting method also called a condolfer method. The auto-transformer starting method is a starting method that reduces the starting current by putting an auto-transformer on the primary side of the pump motor and starting it at low voltage. If the tap of the auto-transformer is a[%], the starting current and starting torque flowing through the motor become a^2[%]. That is, if the starting current is lowered by 1/a, the starting current and starting torque flowing into the power supply becomes 1/a^2 compared to the full voltage starting. The starting current can be reduced by up to 25%, and since the starting torque is good, large-capacity motors can also be started smoothly.

Therefore, since the starting current [Is] = a^2 = 0.65^2 = 0.4225[Is] at 65% of the auto-transformer tap, the starting current of the auto-transformer starting method can be lowered by 34.4% compared to the starting current of the reactor starting method.

By applying such a single winding transformer starting method, there is an advantage that the pump motor can be started even with a small capacity emergency generator and transformer in case of a power failure due to a power outage or an internal power system accident. Therefore, it is possible to obtain the effect of reducing costs by reducing the capacity of the emergency generator provided in preparation for a power outage.

In general, when a high-pressure pump motor is used, the starting current is 5 times higher than usual when starting (5 times the current is required when starting the pump, and 500kW of generator is required when starting the pump 100kW). Therefore, it is expensive to provide an emergency generator having a capacity 5 times the normal capacity as described above, so it is often not possible to install an emergency generator of the same level. In this case, there was a problem in that water supply was interrupted for a long time during power outage. However, when using the single-winding transformer starting method as in the present invention, since the pump motor can be started only with a relatively low-capacity emergency generator, it is possible to reduce the installation cost of the emergency generator and significantly reduce the damage of power supply interruption. .

On the other hand, the safe movable type carbon neutral switchgear system capable of emergency response according to the present embodiment includes an integrated power monitoring module 800 . The integrated power monitoring module 800 monitors the power used by the pump motor control unit 850 and the low pressure control unit 870 , stores monitoring data, and displays it through the display panel 810 .

As described above, the pump motor control unit 850 supplies power to the pump motor and controls its operation. The integrated power monitoring module 800 measures the total load (100%) voltage, current, power amount, etc. of the pump motor control unit 850 and monitors it in batches, analyzes the power usage and various collected data, and displays it on the display panel 810 . displayed through

In the case of some conventional switchgears, the power monitoring system was installed and operated only in the pump facilities, which accounted for 95% of the total power.

However, in order to realize the global trend of carbon neutrality and increase the use of new and renewable energy, not only the pump facility but also the power usage status of general loads that drive other components such as valves are integrated and managed, and data that can be analyzed and managed optimally need to manage Based on such data, optimal management of power use is performed to analyze the amount of power generation and power consumption of new and renewable energy such as solar power to indicate the carbon neutrality ratio Active and optimized management is possible.

To this end, the safe movable carbon neutral switchgear system capable of emergency response according to this embodiment includes a low pressure control unit 870 and monitors the power consumption of the low pressure control unit 870 and integrates it with the power used by the pump motor control unit 850. will manage The low pressure control unit 870 is configured to supply and control power to general facilities other than the device to which the pump motor control unit 850 supplies power. However, such a low voltage control unit 870 has a large amount compared to the power consumption, so it may take a lot of cost to individually install the power monitoring device, but the integrated power monitoring module 800 of this embodiment is installed in the low voltage control unit 870 . It is configured to monitor the power used by the low voltage control unit 870 and display it on the display panel 810 using a signal of a current transformer (CT). In this way, it is possible to monitor and integratedly manage the power consumption by using the configuration of the existing current transformer, etc. without installing a new facility in the conventional low-pressure control unit 870 used previously.

As described above, the integrated power monitoring module 800 of the safe movable carbon neutral switchgear system capable of responding to an emergency according to this embodiment is 100% by monitoring not only the pump motor control unit 850 but also the power used by the low pressure control unit 870 . It has the advantage of being able to monitor the power used and, as a result, establish a stable and efficient power operation management and energy saving plan based on the integrated monitoring data to establish a carbon-neutral system.

The integrated power monitoring module 800 monitors and stores voltage, power factor, power, and frequency data, and displays it on the display panel 810 in real time. In addition, the integrated power monitoring module 800 processes and displays the monitored and stored data by various statistical methods for each date and time as described above on the display panel 810 . For example, the integrated power monitoring module 800 displays the monitoring data on the display panel 810 by organizing the monitoring data into statistical data and graphs for each date and time. In addition, the integrated power monitoring module 800 not only analyzes and predicts power usage by machine learning or AI techniques, but also analyzes in conjunction with the production, supply, and usage of new and renewable energy to optimally manage the use of power to achieve carbon neutrality. function to make it effective.

In addition, the integrated power monitoring module 800 uses the touch LCD of the display panel 810 for overall power monitoring and electrical drawing maintenance (failure/check/ replacement history, etc.) and crisis response manuals, etc. can be efficiently managed. By configuring in this way, it is possible to quickly respond to various situations in the field in case of an emergency.

On the other hand, the case of using the safe movable carbon neutral switchgear system capable of emergency response according to the present invention for the purpose of supplying power to the water supply pump has been described as an example, but the scope of the present invention is used for the water supply pump It is not limited thereto and may be used in various fields requiring high voltage power.

In addition, the safety movable carbon neutral switchgear system capable of responding to an emergency of the present invention can prevent earthquakes and electric shock accidents by installing an insulating cover on the cable head. With such a configuration, it is possible to prevent the occurrence of an electric shock accident that may occur during inspection due to the exposure of the head of the extra-high voltage cable.

The insertion connector 120 is connected to the opposite end of the terminal coupling part 110 and is formed. The insertion connector 120 is formed in a circular motion shape. As shown in FIGS. 4 and 5 , irregularities are formed on the outer diameter of the insert connector 120 along the circumferential direction of the outer diameter.

The cover member 200 is formed of a synthetic resin material (epoxy) to cover and insulate the insertion member 100 and a portion of the cable head 10 coupled to the insertion member 100 . The cover member 200 of this embodiment is formed in the form of a container having a main body of a cylindrical shape. As such, the cover member 200 has a guide inner diameter portion 210 in the form of a cylindrical cylinder. A portion of the cable head 10 and the insertion member 100 are inserted into the guide inner diameter 210 to be protected and insulated.

The guide inner diameter portion 210 of the cover member 200 is formed such that the inner diameter gradually decreases as it enters inward.

The connector member 300 includes a holder connector 310 , a cover terminal 330 , and a connector connection part 320 . The connector member 300 of this embodiment is integrally formed.

The holder connector 310 is formed in a cylindrical container shape so that the insertion connector 120 of the insertion member 100 is inserted and connected. In the present embodiment, the holder connector 310 is disposed at the inner end of the guide inner diameter 210 of the cover member 200 and is installed to be embedded in the cover member 200 , and the cylindrically concave portion serves as the guide inner diameter portion 210 . placed to be exposed. The insertion connector 120 of the insertion member 100 is fitted to the holder connector 310 via the guide inner diameter portion 210 . Since the holder connector 310 is installed to be embedded in the cover member 200 made of synthetic resin, the insertion connector 120 is stably pressed by the elasticity of the cover member 200 and the elasticity of the holder connector 310 by itself. to maintain an electrical connection to each other.

The cover terminal 330 is formed to protrude to the outside of the cover member 200 . The cover terminal 330 is formed in a structure similar to the terminal coupling portion 110 of the insertion member 100 .

The connector connection part 320 is formed to connect the holder connector 310 and the cover terminal 330 . The connector connection part 320 is installed to be embedded in the inside of the cover member 200 . The holder connector 310 , the connector connection part 320 , and the cover terminal 330 are integrally formed.

The cover terminal 330 is formed to protrude with respect to the cover member 200 in a direction perpendicular to the direction in which the guide inner diameter 210 of the cover member 200 extends (that is, the extension direction of the cable head 10). . Accordingly, the connector connection part 320 is formed in a structure that is bent at a right angle so that the holder connector 310 and the cover terminal 330 can be connected. A portion of the cover member 200 corresponding to the connector connection part 320 is also formed in a structure that is bent at a right angle.

The cover member 200 further includes cover flanges 230 and 240 . The cover flanges 230 and 240 are formed in a disk shape protruding from the outer periphery of the cover member 200 at a position close to the portion from which the cover terminal 330 of the connector member 300 protrudes. The cover flanges 230 and 240 are formed to protrude in a direction perpendicular to the extending direction of the cover terminal 330 .

In this embodiment, as shown in FIGS. 4 and 5 , the cover member 200 includes two cover flanges 230 and 240 . The cover flanges 230 and 240 serve to prevent an electric shock by inadvertently contacting the cover terminal 330 or the bus bar 20 by a user or an inspector.

A live line display lamp 410 is installed on the outer surface of the cover member 200 . The live line display lamp 410 is composed of an LED element. When the live line indicator lamp 410 is turned on, it indicates that current flows in the connector member 300 of the present embodiment.

The live line display lamp 410 is lit by the current flowing through the lamp coil 420 . The lamp coil 420 is installed to be embedded in the cover member 200 and is electrically connected to the live line display lamp 410 . A power supply means such as a separate battery is not connected to the lamp coil 420 . A current induced by electromagnetic waves generated by AC power flowing through the insertion member 100 flows to the lamp coil 420 , and the live line display lamp 410 is turned on when a current flows through the lamp coil 420 . In some cases, when the live line indicator lamp 410 is turned on, it is also possible to configure the live line indicator lamp 410 so that the text “in live line” is displayed.

Hereinafter, a method of using the cable head cover unit configured as described above will be described.

The power transmission line is in a state in which the cable head 10 as shown in FIGS. 4 and 5 is installed.

In this state, the terminal coupling part 110 of the insertion member 100 configured as described above is coupled to the terminal 11 of the cable head 10 . The terminal 11 and the terminal 11 of the cable head 10 are coupled to each other using a bolt.

In this state, as shown in FIG. 6 , the insertion member 100 is inserted into the guide inner diameter portion 210 of the cover member 200 . As described above, the inner diameter of the guide 210 is formed so that the inner diameter decreases as it enters the inside. Accordingly, the insertion connector 120 of the insertion member 100 is aligned with the center line of the guide inner diameter portion 210 as it enters the inner diameter of the guide inner diameter portion 210 and is aligned to a position corresponding to the holder connector 310 . At this time, while the outer diameter of the cable head 10 enters along the guide inner diameter portion 210, the position of the insertion connector 120 with respect to the holder connector 310 is automatically aligned.

In this state, when the cover member 200 and the cable head 10 are pressed in a mutually close direction, the insertion connector 120 is fitted with the holder connector 310 and interconnection is made.

As described above, since at least a portion of the holder connector 310 is embedded in the cover member 200 , the holder connector 310 receives the elastic support of the cover member 200 made of synthetic resin and the insertion connector 120 is inside. ) is allowed to fit and maintains a stable electrical and mechanical bond.

In this state, as shown in FIG. 6 , the cover terminal 330 is connected to the bus bar 20 of the switchboard. The cover terminal 330 and the bus bar 20 are coupled to each other using bolts in a similar way to the connection between the terminal coupling unit 110 and the terminal 11 of the cable head 10 in the previous section.

As described above, since the cover member 200 and the connector connection part 320 are formed in a shape bent at a right angle, it is easy to connect the power line extending underground and the bus bar 20 of the switchboard as shown in FIG. 6 . There are advantages. The power line is vertically extended with respect to the ground, and the cover terminal 330 is connected to the horizontally arranged bus bar 20 . Due to the structure of the cable head cover unit as described above, it is possible to occupy a relatively small space for power line connection, and to configure the switchgear in a relatively small size.

On the other hand, as described above, the cover member 200 is provided with cover flanges 230 and 240 having a disk structure extending in a direction perpendicular to the extending direction of the cover terminal 330 . Such cover flanges 230 and 240 serve to protect the operator or inspector from electric shock. The cover terminal 330 and the bus bar 20 through which a high voltage current flows have an exposed outer surface without being insulated. will prevent access. Accordingly, it is possible to obtain the effect of preventing an electric shock accident due to the carelessness of the operator during inspection or use.

In addition, as described above, the live line display lamp 410 is installed on the cover member 200 , and in the live line state, the live line display lamp 410 is configured to be turned on. Accordingly, the user can intuitively determine whether a high-voltage current is flowing in the power line, and can safely perform maintenance or inspection.

In particular, since the live line display lamp 410 is lit using electromagnetic waves generated by a high-voltage current flowing inside the cover member 200 without using a separate power source, it has a simple structure and prevents malfunction. Accordingly, the live line display lamp 410 may have excellent durability, operate efficiently, and play an extremely excellent role in preventing safety accidents.

Although the cable head cover unit used in the present invention has been described as a preferred example, the scope of the cable head cover unit is not limited to the above-described and illustrated form.

For example, although it has been previously described that the live line display lamp 410 and the lamp coil 420 are installed in the cover member 200 , the cable head has a structure that does not include the live line display lamp 410 and the lamp coil 420 . It is also possible to constitute a cover unit.

In addition, the inner diameter of the guide inner diameter portion 210 of the cover member 200 has been described as decreasing as it enters the inside, but in some cases, the inner diameter of the guide inner diameter portion 210 is recognized along the longitudinal direction. It is also possible

In addition, the cable head cover unit having a structure in which the holder connector 310 is not installed in a structure that is embedded with respect to the cover member 200 but is installed in a form in which the entire guide inner diameter portion 210 of the cover member 200 is exposed. It is also possible to

In addition, although it has been described before that irregularities are formed on the outer peripheral surface of the insert connector 120 , irregularities may be formed on the inner peripheral surface of the holder connector 310 , and irregularities are formed on both the insert connector 120 and the holder connector 310 . It is also possible to use structures. In some cases, irregularities may not be formed in both the insertion connector 120 and the holder connector 310 .

In addition, the number and structure of the cover flanges 230 and 240 may be variously modified as necessary. In some cases, it is also possible to configure the cable head cover unit of a type that does not include the cover flanges (230, 240).
