The present invention relates to a security control management method and system of the switchboard. It is comprised of an alert portion (A1) connected to the input of the display unit (D1), a current watch controller (CC) which is connected to the input of the current transformer (K4), the current watch controller (CC) which is connected to the input of the setting unit (S1) sensing the abnormal current of the absorber (SA), a current watch controller (CC) connected to the input of the current watch controller (CC) and the input is connected to the input of the current transformer (K2), the current watch controller (CC) sensing the abnormal current of the lightning arrester (LA) and the input is connected to the input of the current transformer (K3), the current watch controller (CC) sensing the abnormal current of the reactor (R) and it is connected to the output of the current transformer (K5), the current watch controller (CC) sensing the abnormal current of the condenser (C). And it can prevent accidents by sensing the malfunction of the current, the abnormal current, the deterioration and dielectric breakdown. Also, quickly reacting to the difference in temperatures, smoke, and arc light, it not only blocks the vacuum interrupter or operates the fire extinguisher to prevent fires or extinguishes the fire but also minimizes the economic loss from such accidents. Overall, the system can be protected through the real-time monitoring. [Reference numerals] (AA) Digital power protection monitoring device |
