[0001] The present invention relates to a power distribution board having a power shutdown system having an earthquake detection function and a driving method thereof,

The present invention relates to a switchboard with a power interruption system having an earthquake detection function and a driving method thereof. More particularly, the present invention relates to a switchboard having a power interruption system having an earthquake detection function, The present invention relates to a switchboard with a built-in system having an earthquake detection function for cutting off supplied power, and a driving method thereof.

Recently, natural disasters are frequent in the world, and earthquakes occur frequently. It is proved that Korea is not a safety zone of earthquake. It is evident that Korea is no longer a safe zone from earthquakes, as earthquakes with a magnitude of 4 or more occur consecutively in the West Sea, and a small number of earthquakes are observed inland. Therefore, the government is planning to add seismic design items to the design standard, and the construction of seismic design is in place for new buildings and apartments, and the demand for seismic design is higher than ever before .

In general, the term "switchboard" is not only a high-rise building using a lot of electricity, but also a building facility that is required in general low-rise buildings. The switchboard is a facility that can receive power from the power supplier, distribute the incoming power to each floor of the building or each of its customers, and effectively control the power system of the building. If the switchboard breaks down or fails, power supply to the entire building will be disrupted.

The seismic design of such switchboards needs to be made. The Applicant Japanese Unexamined Patent Publication No. 10-1049407 discloses a seismic isolation panel having a non-directional elastic support, which is a technique for preventing damage to an enclosure of an ASSEMBLY and a unit device installed in the interior of the ASSEMBLY from an external shock such as an earthquake .

However, even if the earthquake-resistant design is applied to the switchboard, if the earthquake strength is severe, the switchboard can not be prevented from being rocked or damaged. In this case, power is still supplied even when the switchboard has lost its function. As a result, there is a high risk of secondary damage such as electric shock or fire. In other words, the earthquake can cause secondary damage such as breakdown or failure of the switchboard itself, primary damage such as short-circuiting or short-circuiting, as well as electric ignition in gas leakage, causing gas explosion, fire, or electric shock . In addition, even if the earthquake strength is weak, it may be necessary to shut off the power to the building before the safety of the building is completely secured. Depending on the needs of the user and the strength of the earthquake, it is necessary to determine whether or not the building is to be shut down under specific criteria.

Accordingly, it is necessary to develop a device capable of shutting off the power of the switchboard when the earthquake occurs in accordance with the earthquake sensitivity, and cutting the power by changing the power cutoff reference value according to the demand of the user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a switchboard with a power shutdown system having an earthquake detection function according to the present invention will be described in detail with reference to the accompanying drawings.

Prior to the description, the switchboard commonly referred to in the present invention refers to a high-voltage switchboard, a low-voltage switchboard, a motor control board, a distribution board, and the like, and refers to a building facility for supplying power to a building.

FIG. 1 is a front view of an electrical switchboard having a power shutdown system equipped with an earthquake sensing function according to an embodiment of the present invention. FIG. 2 is a schematic view of a power switchboard having an earthquake sensing function according to an embodiment of the present invention, 3 is a diagram illustrating a state in which a reduction sensor module of a power shutdown system having an earthquake sensing function according to an embodiment of the present invention is installed in a building. FIG. 5 is a block diagram illustrating an internal configuration of a power shutdown system incorporating an earthquake detection function according to an embodiment of the present invention. And Fig.

As shown in FIGS. 1 to 4, the power shutdown system 10 having an earthquake sensing function according to the present invention includes at least one seismic-sensor module 100 for detecting the occurrence of an earthquake, A transceiver 200 for transmitting and receiving the sensed value of the attenuation sensor module 100 by wireless communication, a reader 300 connected to the transceiver 200 for measuring the sensitivity of the earthquake, A control unit 400 for controlling the display unit 600, the display unit 600 and the memory unit 500, a display unit 600 for indicating whether various signals are generated, And a memory unit 500 for storing sensing values of the display unit 100 and the like. These configurations may be accommodated in the interior of the switchboard 1 or attached to one side of the switchboard 1 and may be freely changed according to the convenience of the user.

As shown in FIGS. 2 and 3, the deceleration sensor module 100 may be provided with a plurality of deceleration sensors 101 installed between the layers in the vertical direction of the building. The reason why a plurality of the deceleration sensors 101 are installed is that the horizontal displacement is larger in a high-level than in a low-level of a building. That is, even if a minute earthquake occurs, the degaussing sensor 101 installed in the upper part of the building, which is relatively higher than the declining sensor 101 installed in the lower part of the building, may have a merit that can detect minute shaking or vibration more accurately. Thus, it is possible to more precisely detect whether an earthquake has occurred or not, and to improve the sensitivity of the damping sensor 101 in measuring the sensitivity of an earthquake.

Each of the deceleration sensors 101 constituting the deceleration sensor module 100 in the present embodiment is provided with a three-axis deceleration sensor 101 for detecting an earthquake or a three-axis deceleration sensor 101 for measuring a minute vibration due to a low frequency (0.1 to 50 Hz) A MEMS sensor may be provided. The acceleration sensor 101 can record and store acceleration data for the sensed vibration in three axial directions. Here, the three axes means that the acceleration due to the vibration and the vibration in the left and right direction as well as the vertical direction can be measured. On the other hand, if vibration or acceleration can be detected in three axial directions, A three-axis gyro sensor, a geomagnetic sensor, a three-axis inertial sensor, or the like, in addition to the deceleration sensor 101 used in the present embodiment.

The transceiver 200 may collect the sensing values sensed by the deceleration sensor module 100 and output the sensing values to the reader 300. [ The detent sensor module 100 is spaced apart from the transceiver 200 by a predetermined distance so that the detent sensor module 100 and the transceiver 200 are connected by wireless communication rather than by wire. Here, a transmitting unit (not shown) for transmitting the sensing values to the transmitting and receiving unit 200 may be provided in the attenuation sensor module 100 corresponding to the reception by the transmitting and receiving unit 200.

The transmitting and receiving unit 200 transmits various information such as a sensing value of the attenuation sensor module 100, a result of the reading unit 300 or an alarm signal and / or a blocking signal of the control unit 400 to the central power control room Or transmitted to the user's portable terminal.

The reading unit 300 may serve to measure the sensitivity of the earthquake. The reading unit 300 is connected to the reduction sensor module 100 and can analyze the acceleration data of the reduction sensor module 100 to determine the degree of progression. That is, the reading unit 300 may compare the seismic sensitivity information of the memory module 500 with the deceleration sensor module 100, and output the result.

Here, the magnitude class can be defined in several categories, but it describes the Modified Mercalli intensity scale (MMI scale). The modified Mercado Jindo class consists of 12 classes and can be classified as shown in [Table 1] according to the magnitude of the earthquake damage. In recent years, including Korea, Japan and other countries have been using the modified Mercado Jindo class to predict seismic sensitivity and damage. Here, progress is generally expressed as an integer of Roman numeral.

magnitude situation One Minor vibration. Very few in special conditions 2 Very few feel indoors 3 Feeling a handful indoors. A hanging object moves weakly 4 Many feel indoors. I can not detect it outdoors. 5 The entire building is shaken. Damage, inversion, or fall of objects. Movement of light objects 6 Difficulty walking straight. The walls of weak buildings fall or crack. Moving or reversing heavy objects 7 It is difficult to stand. I feel an earthquake while driving. Loose wall and fence collapsed 8 Difficulty driving a car. Some buildings collapsed. Cracks in slope or surface. Tower, chimney collapse 9 Severe building damage or collapse. Cracks occur in the surface and pipe damage 10 Most rugged buildings and structures destroyed. Surface cracks, large-scale events, asphalt cracks 11 The railway is heavily bent. The structure is almost destroyed. Underground pipe can not be operated 12 The ground moves in wave form. The object jumps into the air

By using the modified Mercurial degree class, it can be quantified to which progress level the acceleration data measured by the deceleration sensor module 100 corresponds.

Referring to FIGS. 2 and 4, the controller 400 drives the deceleration sensor module 100 and analyzes the seismic sensitivity of the reader 300 to generate an alarm signal according to the seismic sensitivity. In addition, the control unit 400 may generate a shutoff signal to shut off the power supply unit 3 and / or the power inlet unit 2.

Here, the internal unit of the switchboard 1 is the same as that of the general switchboard 1, and is not shown. The switchboard 1 is a unit device related to the power cutoff system. There may be a power inlet portion 2 through which power is drawn into the building and a power supply portion 3 supplying power to the building. The control unit 400 is provided between the power input unit 2 and the power supply unit 3 and cuts off power of the power supply unit 3 and / or the power input unit 2 according to a result of the reading unit 300 A blocking signal can be generated. For example, in the case of the intensity of 5-6, the power of the power supply unit 3 may be cut off, and the power supply unit 3 and the power input unit 2 may be cut off when the magnitude is 6 or more. It is possible to perform the power cutoff function simply and quickly by shutting off the power of the building supply unit 3 at a scale of 5 or less in the degree of magnitude and to recover the power easily. If the intensity is greater than or equal to 5, the power input unit 2 itself may be cut off and the power supplied to the switchboard 1 may be completely cut off. If the power itself does not enter the building, it will prevent secondary damage such as fire or explosion. Of course, in this case, the information of the blocking signal may be supplied to the power supply organization receiving the signal, and the power of the power line supplied to the building by the power supply institution may also be cut off.

Such a power cutoff reference value may be variously changed according to the needs and needs of the user. The reference value may be changed in consideration of the specific criteria of the modified Merckelian progress rank.

The display unit 600 may be installed on the front surface of the switchboard 1 as shown in FIG. The display unit 600 may display a sensing value of the decaying sensor module 100, a result of the reading unit 300, or a blocking signal of the controller 400. [ Through the display unit 600, it is possible to obtain information more easily and accurately when an earthquake occurs.

The memory unit 500 may store information on the degree of magnitude and may also store the earthquake sensitivity results.

Meanwhile, the power shutdown system 10 having an earthquake detection function may further include an alarm unit 700 provided with an alarm sound and an alarm light (not shown). The alarm unit 700 is connected to the controller 400 as shown in FIG. 4, and the alarm unit 700 can be driven by the alarm signal when an earthquake occurs.

In this manner, when the earthquake occurs in response to the earthquake sensitivity, the power cut-off system is activated to automatically shut off the power of the switchboard to prevent accidents such as short-circuit or short-circuit in the building, It is possible to prevent the secondary damage such as fire or the like and to reduce loss of life and property.

6 is a flowchart illustrating a power shutdown system having an earthquake detection function according to an embodiment of the present invention.

Hereinafter, a power cut-off system 10 having an earthquake detection function having such a configuration will be described in detail with reference to FIG. 6 as follows. The driving method will be described in the description of the configuration of the power shut-off system as long as it does not overlap.

First, a step of detecting the occurrence of an earthquake may be performed (S110). The degradation sensor module 100 can check whether or not an earthquake has occurred. By using a plurality of detent sensors, it is possible to calculate whether or not an earthquake occurs precisely even in a minute earthquake. This is because, even if an earthquake having an intensity that can not be detected in the lower part of the building due to a plurality of deceleration sensors 101 installed in the vertical direction of the building, there is an advantage that the vibration and vibration are amplified in the upper part of the building, It is because.

The sensed values of the attenuation sensor module 100 may be transmitted to the transceiver 200 through a transmission unit built in the attenuation sensor module 100 in operation S120. The sensed value of the attenuation sensor 100 may be transmitted to the reader 300 via wireless communication.

The reading unit 300 may analyze the stored acceleration data and measure the seismic sensitivity (S130). At this time, the seismic sensitivity measurement is based on the modified Merckelian progress chart to determine the degree of progress.

Thereafter, the seismic sensitivity and a preset value are determined (S140). If the value of the seismic sensitivity is not transmitted, the seismic sensitivity and the seismic sensitivity measurement may be fed back. In this case, the control unit 400 may transmit an alarm signal corresponding to a value equal to or less than the value of the earthquake sensitivity to the alarm unit 700, and may be operated to notify the user by driving an alarm signal, an alarm sound or an alarm lamp (S150) .

(S160). If the seismic sensitivity is equal to or greater than a set value (in the present embodiment, the intensity is 5), an alarm signal corresponding thereto is generated (S160) and the power input unit / RTI > and / or the power supply 3 (S170).

Next, it is necessary for the user to stop the alarm signal and the shutoff signal when it is judged that the occurrence of the earthquake is terminated or not the emergency state. At this time, when the user inputs a shutoff signal cancel command through the display panel 600 provided in the general power panel of the power central control room or the display panel 600 of the switchboard 1 in step S180, the reset sensor module 100 is reset And the step of interrupting the alarm signal and the shutoff signal of the control unit 400 may be performed (S190).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. It will also be appreciated that many modifications and variations will be apparent to those skilled in the art without departing from the scope of the present invention.
