The present invention relates to a private generator having an automatic switching function to fire extinguishment, the private generator having a main power circuit breaker and a circuit breaker for power interruption and a circuit breaker for fire extinguishment branched from the lower end of the main power circuit breaker, the private generator including: a measuring in¬ strument adapted to sense the state of the generation of fire by the variations of a power load on a main power line; and a control instrument connected to the measuring instrument at an input side thereof and connected to the circuit breaker for power interruption 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 power interruption is primarily broken, thereby keeping the main power circuit breaker from being broken before the breaking of the circuit breaker for power interruption. |
