Description

Electronic equipment protection system using space charge sensing The present invention relates to an electronic equipment protection system using space charge sensing, which sets a risk level based on changes in space charge values measured in the atmosphere, differentially classifies the risk level according to the type of electronic equipment connected to the surge protection device, and blocks the connection of the electronic equipment from the surge protection device when the space charge value corresponds to the risk level, thereby preventing damage caused by lightning current during a lightning strike. Lightning is a phenomenon in which electric charges carried by thunderclouds are released into the atmosphere through the breakdown of air insulation; during this process, an electromagnetic field is generated and propagates through the atmosphere. Technology for analyzing the location of lightning strikes predicts thundercloud activity, movement paths, and the occurrence of lightning, and is being applied as a means of implementing measures to prevent damage caused by lightning in buildings and power facilities. Conventional lightning warning systems are configured to install lightning detectors in arbitrary areas, process and analyze various lightning information collected from the installed detectors when lightning occurs, and transmit lightning warnings or lightning information to the relevant management agency in real time. However, conventional lightning warning systems have the problem that it is difficult to respond quickly to lightning strikes because they cannot issue a warning before the lightning strike occurs, as they can only collect information about lightning strikes.

FIG. 2 is a block diagram of a surge protection device according to the present invention. FIG. 3 is a block diagram of a risk prevention center according to the present invention. FIG. 4 is a flowchart of an electronic equipment protection process using space charge sensing according to the present invention. The following detailed description of preferred embodiments of the present invention will be explained with reference to the accompanying drawings. Specific details are provided in the following description to aid in a more comprehensive understanding of the present invention. Furthermore, in describing the present invention, detailed descriptions of related known functions or configurations are omitted if it is determined that such detailed descriptions would unnecessarily obscure the essence of the present invention. As illustrated in FIG. 1, the electronic equipment protection system using the space charge sensing of the present invention comprises a space charge sensor (100) that measures the space charge of the atmosphere, a surge protection device (200) that connects or disconnects electronic equipment installed in a building, and a cutoff risk prevention center (300) that receives the measured value of the space charge measured by the space charge sensor (100), checks the risk level for lightning strikes, and provides a cutoff signal to disconnect the connected electronic equipment or a release signal to release the disconnection according to the risk level to the surge protection device (200). A space charge sensor (100) is installed on the top or outer side of a building to measure the space charge of the atmosphere. At this time, the space charge sensor (100) measures the amount of charge formed in the space when a ground charge is formed between a thundercloud and the ground, and the measured space charge value is provided to the risk prevention center (300) in real time. As illustrated in FIG. 2, the surge protection device (200) connects or disconnects electronic equipment installed in a building to protect the electronic equipment against overcurrent during normal operation and prevents lightning current from flowing back into the electronic equipment. This surge protection device (200) includes an electronic equipment connection part (210), an electronic equipment disconnection management part (220), and an electronic equipment disconnection release part (230). The electronic equipment connection unit (210) classifies and connects electronic equipment used in a building or facility by risk level. At this time, the electronic equipment connection unit (210) stores a list of connected electronic equipment. The electronic equipment blocking management unit (220) blocks the connection of the corresponding electronic equipment when it receives blocking information of the electronic equipment from the risk prevention center (300). When the electronic equipment unblocking unit (230) receives unblocking information for electronic equipment from the risk prevention center (300), it unblocks the corresponding electronic equipment and reconnects it.
