The present invention relates to an emergency generator power system with reserved fire protection power used for fire protection systems and other emergencies at the time of stop of supplying of normal power and comprising a generator engine and a generator body, a main power circuit breaker, a control panel, and a circuit breaker for fire protection systems and a circuit breaker for other emergencies branched therefrom respectively. The present invention is characterized in that, when a fire and an interruption of power occur in buildings or facilities in which the emergency generator power system is to be installed, power load other than power load for fire protection systems is primarily interrupted, thereby emergency power is safely supplied to the power load for fire protection systems. The construction for achieving the object of the present invention is characterized in that the emergency generator power system comprises a measuring instrument adapted to measure the state of increase of a power load on a main power line passing via main power circuit breaker; and a control instrument connected to the measuring instrument at an input side thereof and connected to the circuit breaker for other emergencies at an output side thereof, such that when the value of the variations of the power load inputted from the measuring instrument reaches a predetermined set value, the circuit breaker for other emergencies is primarily broken, thereby keeping the main power circuit breaker from being broken before the breaking of the circuit breaker for other emergencies. |
