The present invention relates to a system for automatically blocking a panel board. The present invention relates to the system for automatically blocking the panel board which automatically blocks panel boards installed inside a building. The system for automatically blocking the panel board comprises a panel circuit unit, the panel board, and a center control unit. The panel circuit unit comprises a main blocking switch, a breaker, an opening/closing device, a timer switch, and first relay and second relay units. The main blocking switch provides common AC power. The breaker comprises a first blocking unit which blocks the power of each load device and a second blocking unit which blocks the power of the panel board. The opening/closing device is connected to the main blocking switch and operates the breaker according to a blocking signal. The opening/closing device is connected to the first relay unit and second relay unit. The timer switch sets an operation time of the opening/closing device in order that the opening/closing device turns on/off in a constant time and comprises a timer for an on/off operation. The first relay and second relay units electrically connect the breaker, the opening/closing device, and the timer switch. The panel board comprises a panel control unit capable of controlling the breaker, the opening/closing device, and the timer switch, operating the timer according to a predetermined work time from the timer switch, and turning on/off the opening/closing device. The center control unit controls the panel board by connecting the panel control unit. |
