DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout.

In the following description of the present invention, 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 terms used throughout the specification of the present invention have been defined in consideration of the functions of the embodiments of the present invention and can be sufficiently modified according to the intentions and customs of the user or operator. It should be based on the contents of.

1 is a schematic diagram of an earthquake-adaptive power transmission system according to the present invention. As shown in Fig. 1, a building is constructed with its own earthquake-resistant design, and a high-voltage electric power transmitted through a high-voltage transmission line is converted into a low-voltage electric power and distributed to a load application (for example, lighting, And a switchboard (100) for outputting to a load line of the building.

The switchgear 100 has a function of shutting off the high-voltage power in the event of a power system failure such as an overload, a ground bar 200 discharging the power remaining in the switchgear 100 to the earth when the high-voltage power is cut off, (Typically 70 cm or more) to the ground.

The earthquake-resistant switchboard 100 according to the present invention can prevent the transmission power inputted to the switchboard from being interrupted according to the absolute earthquake intensity (magnitude) comparison method when an earthquake occurs, So that the power distribution management can be performed more safely in the event of an earthquake.

2 is a block diagram showing a configuration of an embodiment of an earthquake-resistant switchboard according to the present invention. 2, the earthquake-resistant switchboard 100 according to this embodiment includes a power receiver 110, a transformer 120, a power distributing unit 130, a parking end 140, An earthquake intensity measuring unit 150, and a control unit 160. [

The power receiver 110 receives high voltage power transmitted through a power lead line. The high-voltage power transmitted through the high-voltage transmission line is received by the power receiver 110 of the switchboard 100 adaptive to the earthquake through the power-in line.

The transformer 120 converts the high voltage power received by the power receiver 110 into low voltage power. The high-voltage power received through the power receiver 110 of the switchboard 100 is converted into low-voltage power at a level usable in the building through the transformer 120 and output.

The power distributing unit 130 distributes the low-voltage power transformed by the transforming unit 120 for each load application, and outputs the low-voltage power to the load line. The distribution according to the load application means that the low-voltage power transformed according to the power use application such as lighting, heating and cooling is divided by the load line and outputted.

The low-voltage power output distributed by the power distribution unit 130 for each load application is distributed to each use destination by at least one distribution board (not shown) installed in the building and used as power supply power of the loads.

The parking end portion 140 is installed at a front end of the power receiver 110 to block high-voltage power that is drawn into the power / For example, the parking end 140 may be implemented as a VCB (Vacuum Circuit Breaker)

The seismic intensity measuring unit 150 measures the seismic intensity. For example, the seismic intensity measuring unit 150 may be implemented to measure the seismic intensity by analyzing the transmitted seismic signal and calculating the absolute seismic intensity. In this case, the earthquake intensity may be an absolute earthquake intensity classified as the intensity 1, the magnitude 2, the magnitude 3, and the like.

When the earthquake intensity measured by the earthquake-resistance measuring unit 150 exceeds a reference strength according to a predetermined building seismic design rating, the controller 160 cuts off the parking end 140, So that the high-voltage power is prevented from being drawn. At this time, each building is constructed with earthquake - resistant design, and the building earthquake - resistant design grade is the information obtained by classifying the earthquake - resistant design by building and digitizing it.

When an earthquake occurs, the earthquake-resistant design of the building is superior to the earthquake-resistant design of an earthquake-resistant building.

This technical problem can be solved technically by blocking transmission power inputted to the switchboard according to the seismic design grade of the relative building, without interrupting the transmission power inputted to the switchboard according to the absolute earthquake intensity (magnitude) As a result, it is possible to manage the power distribution more safely in case of an earthquake.

According to a further aspect of the present invention, the earthquake-resistant switchboard 100 may further include a vibration detection unit 170 and a power supply anomaly detection unit 180. The vibration sensing unit 170 senses the vibration of the transmission / reception system itself. The power supply abnormality sensing unit 180 senses a power supply abnormality of the power receiver 110 or the transformer 120 or the power distributing unit 130.

Here, the vibration of the switchboard itself refers to a physical shock applied to the switchboard due to an earthquake or other physical impact, and a power failure refers to an unexpected abnormality such as an overload due to equipment breakage, It says.

In this case, when the control unit 160 senses a vibration of a predetermined intensity or more by the vibration sensing unit 170 or a power source abnormality is detected by the power source abnormality sensing unit 180, It is possible to perform safe water distribution management by controlling the high voltage power to be prevented from being drawn into the switchboard 100.

According to a further aspect of the present invention, the earthquake-resistant switchboard 100 may further include an emergency power source unit 190 and an emergency recovery unit 192. The emergency power source unit 190 supplies a low-voltage power emergency power source. For example, the emergency power supply 190 may be implemented as an uninterruptible power supply (UPS) that provides auxiliary power to the switchboard 100 when the parking end 140 is shut off.

The emergency recovery unit 192 selectively allows the low-voltage power source supplied by the emergency power source unit 190 to be selectively supplied to the load lines distributed by the load application by the power distributing unit 130. For example, the emergency recovery unit 192 may be implemented as an MCCB (Molded Case Circuit Breaker).

At this time, after the controller 160 cuts off the parking end 140, the control unit 160 selects a load line for a specific load application, and the low-voltage power source supplied by the emergency power source unit 190 is connected to a load line So as to restore the load line for the specific load application.

When the parking end 140 is blocked due to the earthquake intensity exceeding the reference strength according to the predetermined building seismic design grade, a power failure occurs in the building. However, in order to safely evacuate the people in the building, a load line for a specific load application that supplies power to a specific load, such as an emergency light or an emergency stairway, should be restored.

The emergency recovery unit 192 causes the low voltage emergency power supply supplied by the emergency power supply unit 190 to be drawn into the load line of the specific load application selected by the control unit 160 after the parking end unit 140 is cut off, Restore the intended load line.

According to a further aspect of the present invention, the earthquake-resistant switchboard 100 may further include an earthquake-resistant design rating setting unit 194 and an earthquake-resistant design rating storage unit 196.

For example, the seismic design class setting unit 194 may be configured to provide a user interface for setting a building earthquake-resistance design rating as a user operation unit (not shown), and to receive and set a building seismic design class.

The seismic design class storage unit 196 stores the building seismic design class set by the seismic design class setting unit 194. For example, the seismic design class storage unit 196 may be a nonvolatile memory such as an EEPROM.

At this time, the control unit 160 compares the reference strength according to the building earthquake-resistant design rating stored in the earthquake-resistant design rating storage unit 196 and the earthquake strength measured by the earthquake strength measurement unit when an earthquake occurs, It is possible to determine whether the reference strength according to the predetermined building seismic design grade is exceeded.

For example, when the control unit 160 generates an earthquake, the reference strength corresponding to the building seismic design rating stored in the seismic design rating storage unit 196 is searched from reference strength reference information for each building seismic design grade, And the earthquake strength measured by the earthquake strength measuring unit.

According to a further aspect of the present invention, the earthquake-resistant switchboard 100 may further include an earthquake sensor 210. The earthquake sensor 210 detects the occurrence of an earthquake and transmits an earthquake signal to the earthquake strength measuring unit 150.

For example, the three-axis acceleration sensor is used as the earthquake sensor 210 to detect the x, y, and z axis displacements of the mass body, and the acceleration of the mass body according to the detected x, y, 150 as an earthquake signal.

According to a further aspect of the present invention, the earthquake-resistant switchboard 100 may further include a ground electrode 220 and a ground switch 198. The ground switch 198 is short-circuited when the parking end 140 is cut off and discharges power remaining in the power receiving unit 110 or the transforming unit 120 or the power supplying unit 130 to the ground through the ground electrode 220 .

When the measured earthquake intensity exceeds a reference strength according to a predetermined building seismic design grade, the controller 160 cuts off the parking end 140 to block high-voltage power from flowing into the switchboard 100, The switch 198 is short-circuited to discharge the electric power remaining in the switchboard 100 to the ground through the ground electrode 220 to protect the switchboard 100.

According to a further aspect of the invention, the earthquake-resistant switchboard 100 may further include a ground bar 200. The ground bar 200 is embedded in the ground at a specific depth, and the earth sensor 210 and the ground electrode 220 are embedded.

The communication unit 199 transmits the control and control system status to the management server 300. The management server 300 can know the status of the server and the server by receiving the status of the server and the server.

For example, the communication unit 199 may be configured to transmit the status of the server / server to the management server 300 using a wireless communication method such as WiFi or Bluetooth, or may be configured to transmit the status of the server / 300). ≪ / RTI >
