Abstract:
1. An emergency generator power system with reserved fire protection power for fire protection systems and other emergencies, the emergency generator power system being used at the time of stop of supplying of normal power and comprising: a main power circuit breaker; at least one circuit breaker for fire protection systems; a circuit breaker for other emergencies branched from the lower end of the main power circuit breaker, a measuring instrument adapted to measure power load variations on a main power line to determine whether a fire emergency event occurs; 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; wherein the circuit breaker for other emergencies is configured to be primarily broken when the value of the measured power load variations reaches a predetermined set value, thereby keeping the main power circuit breaker from being broken before the breaking of the circuit breaker for other emergencies, wherein an emergency power is supplied to a power load for fire protection systems and a power load for other emergencies at the same time until the emergency generator power systems reaches an overload state during fire, and finally the supply of the fire protection power is primarily kept, thus the emergency power is continuously supplied to the power load for fire protection systems.
