DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an apparatus and method for monitoring an electrical fault according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. Although the present invention has been illustrated herein as monitoring the occurrence of faults in airport power equipment associated with the airport sign character, the occurrence of faults in power facilities associated with, for example, security, street lights, traffic lights, etc., may also be monitored.

1 is a diagram showing an example of the configuration of a network including an electric fault monitoring apparatus according to an embodiment of the present invention.

Referring to FIG. 1, a network 100 including an electrical fault monitoring apparatus according to an embodiment of the present invention includes an airport power equipment 101, an electrical fault monitoring apparatus 103, a short circuit alarm 105, (107).

The airport power equipment 101 can supply power, for example, as a power supply, with an airport sign character. At this time, the airport power equipment 101 can supply power to the airport sign character through the primary power source, and if the failure occurs, the power source secondary side can be turned off.

The electric disturbance monitoring device 103 judges whether a fault has occurred in the airport electric power equipment associated with the sign of the airport. If it is determined that the fault has occurred, the electric disturbance monitoring device 103 transmits fault occurrence information for the airport electric power equipment 101 to the electric power monitoring device 107 , So that it can be reflected in the abnormality of each airport electric power equipment. Here, when the power source secondary side is turned off due to the occurrence of the fault in the airport power equipment 101 that supplies power through the primary power source with the sign of the airport sign, And a grounding device for operating the earth leakage alarm by performing grounding by shorting the N phase of the primary power source and the ground wire for a predetermined time.

The earth leakage alarm 105 can operate in conjunction with grounding in the grounding device in the electrical fault monitoring device 103 and can receive fault occurrence information for the airport power equipment 101 from the electrical fault monitoring device 103 , It is possible to transmit the fault occurrence information to the electrical fault monitoring apparatus 103.

The electrical fault monitoring apparatus 103 outputs an abnormality of each airport electric power equipment so that the manager can recognize the occurrence of a fault in the airport electric power equipment. The electric fault monitoring apparatus 103 receives fault occurrence information for the airport electric power equipment 101 from the electric fault monitoring apparatus 103 via the leakage alarm 105 so that abnormality of the electric power disturbance monitoring apparatus 103 (For example, flashing display) on the screen or outputting an alarm sound.

2 is a diagram showing a configuration of an electrical fault monitoring apparatus according to an embodiment of the present invention.

Referring to FIG. 2, an electrical fault monitoring apparatus 200 according to an embodiment of the present invention may include a determination unit 201, a grounding apparatus 203, and a processor 205.

The determination unit 201 may compare the output brightness at the airport sign character (or a vowel or consonant in the character) with the set value to determine whether a failure has occurred in the airport power equipment associated with the airport sign character. At this time, if the output brightness for at least one character among the airport sign characters is less than the set value, or if the output brightness for characters over a set number of characters among the airport sign characters is less than the set value, It can be judged that the equipment has failed. For example, when the output brightness of the 'J' of the 'J International Airport' is less than the set value, the judging unit 201 judges that the 'J International Airport' The airport's electrical equipment) can be judged to have failed.

When the power source secondary side is turned off due to the occurrence of the fault in the airport power equipment that supplies power through the power source primary side with the sign of the airport sign, the grounding device 203 detects the N phase of the power source primary side and the ground line Shorted for a set time, and grounded to operate the leak alarm. At this time, the grounding device 203 may be energized for a predetermined time (for example, 1 second) at a current equal to or lower than a set value (for example, 1A) and then grounded and then opened.

When it is determined that a failure has occurred in the airport power equipment, the processor 205 confirms the identification information of the airport power equipment and transmits the failure occurrence information including the identification information to the power monitoring unit, Reflect. For example, when a failure occurs in the airport electric power equipment of the 'J international airport', the processor 205 confirms the identification information of the airport electric power equipment of the 'J international airport', generates failure occurrence information including the identification information, By transmitting to the surveillance device, the power surveillance device outputs the abnormality of the airport power equipment of the 'J international airport', thereby allowing the manager to recognize that the airport power equipment of the 'J international airport' is abnormal.

When the failure occurrence information is transmitted, the processor 205 adds a character (e.g., 'ball') whose output brightness is less than the set value, a location of the airport power equipment (e.g., GPS (Global Positioning System) And at least one of the time of occurrence of the failure and the time of occurrence of the failure.

In addition, when transmitting the failure occurrence information, the processor 205 may transmit the failure occurrence information to the power monitoring apparatus through the operated leak alarm by the earthing device 203 when the leakage alarm is operated.

Meanwhile, when the output brightness of the airport sign character is less than the set value, the processor 205 transmits the fault occurrence information for the airport electric power equipment to the electric power monitoring apparatus as it is determined that the airport electric power equipment has failed, By limiting the transmission of the fault occurrence information to the power monitoring apparatus when the character whose output brightness is less than the set value is a set symbol (e.g., ♥ (heart), exclamation point (!)) , It is possible to omit the fault notification in the event of a failure in the airport power equipment.

As another example, the processor 205 may determine a fault class based on whether the number of characters whose output brightness is less than the set value or the character whose output brightness is less than the set value is a symbol, Information can be further included in the information and transmitted to the power monitoring apparatus. At this time, the processor 205 can determine the fault class as an upper class (for example, 1 class) as the number of characters whose output brightness is less than the set value is determined. If the character whose output brightness is less than the set value is not a symbol, It can be determined to be a higher grade.

The processor 205 may limit the transmission of the fault occurrence information to the power monitoring apparatus when the character whose output brightness is less than the set value is a set symbol but may determine whether the character whose output brightness is less than the set value is a symbol When the determined failure class is included in the failure occurrence information, the failure occurrence information is transmitted to the power monitoring apparatus so that the administrator can grasp the importance based on the failure class.

3 is a view for explaining an example of a failure occurrence notification in the electrical fault monitoring apparatus according to an embodiment of the present invention.

Referring to FIG. 3, the electrical fault monitoring device 300 compares the output brightness at the airport sign character 301 with a set value, and when the output brightness is below the set value, (Not shown) can be judged as a failure. For example, when the brightness of the output of the airport sign character 301 of 'J International Airport' is less than the set value, the electric obstacle monitoring device 300 may monitor the electric sign of the airport sign character 301 of 'J International Airport' It can be judged that a fault has occurred in the airport electric power equipment (airport electric power equipment of 'J international airport').

At this time, the electric disturbance monitoring apparatus 300 uses the grounding device to detect the occurrence of a fault in the airport electric power equipment of the 'J International Airport' that supplies the power through the primary power source at the airport sign character of 'J International Airport' Accordingly, when the secondary side of the power source is turned off, the N phase of the primary side of the power source and the ground line may be short-circuited for a set period of time and grounded to operate the leakage alarm 303.

The electrical fault monitoring apparatus 300 confirms the identification information of the airport electric power equipment of the 'J international airport', generates the fault occurrence information including the identification information, and transmits the fault occurrence information to the power monitoring apparatus 305 So that the power monitoring device 305 can output an abnormality in the airport electric power equipment of the 'J international airport'.

4 is a flowchart illustrating an electrical fault monitoring method according to an embodiment of the present invention.

Referring to FIG. 4, in step 401, the electrical fault monitoring device may compare the output brightness at the airport sign character to a setpoint to determine if a failure has occurred in the airport power equipment associated with the airport sign character.

At this time, if the output brightness for at least one character among the airport sign characters is less than the set value, or if the output brightness for characters over the set number of characters of the airport sign character is less than the set value, It can be determined that a failure has occurred. For example, if the output brightness of the 'JAS' among the airport signs of the 'J International Airport' is less than the set value, the electric disturbance monitoring device may detect an airport power device ('J International Airport' Of the airport's electrical power equipment).

On the other hand, in the electric power failure monitoring device, when the power supply secondary side is turned off due to the occurrence of the fault in the airport electric power equipment that supplies electric power through the power primary side in the sign of an airport using a grounding device, The N phase and the ground wire of the grounding wire can be short-circuited for a set time, and grounding can be performed to operate the earth leakage alarm. At this time, the grounding apparatus can be opened after conducting the grounding by energizing for the set time with a current equal to or lower than the reference value.

In step 403, the electrical disturbance monitoring device can identify the identification of the airport electrical power equipment if it is determined that the failure has occurred.

In step 405, the electrical failure monitoring device transmits the failure occurrence information including the identification information to the power monitoring device, and reflects the failure occurrence information according to the airport electrical power equipment. For example, in the event of a fault in the airport electric power equipment of the 'J International Airport', the electric fault monitoring device generates fault occurrence information including the identification information of the airport electric power equipment of the 'J international airport' The surveillance device outputs an error to the airport electric power equipment of the 'J international airport', thereby allowing the manager to recognize that the airport electric power equipment of the 'J international airport' is abnormal.

When the failure occurrence information is transmitted, the electrical failure monitoring device displays a character (e.g., 'ball') whose output brightness is less than the set value, a location of the airport power equipment (e.g., GPS (Global Positioning System) And at least one of the time of occurrence of the failure and the time of occurrence of the failure.

Meanwhile, when the output brightness of the airport sign character is less than the set value, the electrical disturbance monitoring device transmits the failure occurrence information to the power monitoring device according to the determination that the failure has occurred in the airport electric power equipment, By limiting the transmission of the fault occurrence information to the power monitoring apparatus when the character whose output brightness is less than the set value is a set symbol (e.g., ♥ (heart), exclamation point (!)) , It is possible to omit the fault notification in the event of a failure in the airport power equipment.

As another example, the electrical disturbance monitoring apparatus may determine the fault class based on whether the number of characters whose output brightness is less than the set value or the character whose output brightness is less than the set value is a symbol, Information can be further included in the information and transmitted to the power monitoring apparatus. At this time, the electric disturbance monitoring apparatus can determine the fault class as a higher class (for example, 1st class) as the number of characters whose output brightness is less than the set value is determined. If the character whose output brightness is less than the set value is not a symbol, It can be determined to be a higher grade.

The electric disturbance monitoring apparatus may restrict the transmission of the fault occurrence information to the power monitoring apparatus when the character whose output brightness is less than the set value is a set symbol, The failure occurrence information may be transmitted to the power monitoring apparatus when the determined failure degree is included in the failure occurrence information.

Embodiments of the present invention provide embodiments of the present invention where the occurrence of a failure in the airport power equipment associated with the airport sign character is transmitted to the power monitoring device for the failure occurrence information for the airport power equipment, To be able to cope.

Also, in the embodiment of the present invention, when the power source secondary side is turned off due to a fault in the airport power equipment that supplies power through the primary power source at the airport sign character, the N phase of the power source primary side and the ground line are set The ground fault is short-circuited, grounding is performed to operate the ground fault alarm, and fault occurrence information on the airport electric power equipment is transmitted to the power monitoring apparatus through the operated electric leak alarm, It is possible to report the faults of facilities in real time.
