Description
Technical Field
The utility model belongs to the technical field of generator electronic speed regulation control, especially, relate to miniwatt low noise sound insulation cabin formula forced air cooling power fan monitor control system.
Background
Along with social development, the problem of peak power failure is more and more prominent, the demand of generator sets is gradually increased, various power supply products are in the market, but the living environment of human beings is damaged to a certain extent, so that the power supply which has stable performance, low noise, strong adaptability, high reliability, high safety and low pollution and can adapt to severe environment is gradually valued by users. At present, most of emergency low-noise power supplies of low-power series are water-cooling mute units which are not suitable for extremely severe environments such as drought, high cold, plateau and high temperature, and the low-power low-noise sound-insulation cabin type air-cooling power supplies are completely cooled by air without consuming cooling liquid or setting a water-cooling system, so that the structure is simplified, and the maintenance cost is reduced. The low-power low-noise sound insulation cabin type air cooling power supply is particularly suitable for places short of water or cold in plateaus, and the problems of water addition, boiling point, freezing and the like do not need to be considered; therefore, the fan monitoring control system design is carried out on the low-power low-noise sound insulation cabin type air cooling power supply, unnecessary loss caused by fan faults is effectively reduced, and the product has higher safety and usability. Future consumption of such products is expected to rise year after year.

In the figure, 1-engine, 2-generator, 3-oil supply electromagnetic valve, 4-inverter, 5-cooling fan, 6-speed sensor, 7-signal line, 8-fan speed monitoring controller, 9-controller power output line, 10-secondary winding, and 11-three intermediate frequency electric energy.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The utility model provides a cabin formula forced air cooling power supply fan monitoring control system gives sound insulation of miniwatt low noise, includes engine 1, generator 2, fuel feeding solenoid valve 3, dc-to-ac converter 4, cooling fan 5, its characterized in that: a rotating speed sensor 6 is arranged in the cooling fan 5, the rotating speed sensor 6 is connected with the input end of a fan rotating speed monitoring controller 8 through a signal line 7, the output end of the fan rotating speed monitoring controller 8 is connected with the power supply end of the oil supply electromagnetic valve 3 through a controller power supply output line 9, and the fan rotating speed monitoring controller 8 is powered by a 12V power supply. The fan rotating speed monitoring controller 8 adopts a PB-FSD310 type fan rotating speed monitoring controller.
The working process of the utility model is as follows:
the inverter 4 converts three-phase intermediate frequency electric energy generated by the generator 2 into single-phase power frequency electric energy through AC-DC-AC conversion, the single-phase power frequency electric energy is output by the inverter 4 and then supplied to the cooling fan 5, the cooling fan 5 operates normally, the fan rotating speed monitoring controller 8 samples signals of the rotating speed sensor 6 through the signal line 7, when the sampled fan rotating speed is normal, the cooling fan 5 is confirmed to work normally, the control part of the fan rotating speed monitoring controller 8 is started formally, and the controller power output line 9 outputs 12V power to supply power to the oil supply electromagnetic valve 3, so that the work is normal. When the cooling fan 5 breaks down, the rotating speed value collected by the fan rotating speed monitoring controller 8 is lower than the rotating speed value when the cooling fan normally works, the fan rotating speed monitoring controller 8 judges that the cooling fan 5 breaks down, the fan rotating speed monitoring controller 8 cuts off a 12V power supply of the oil supply electromagnetic valve 3 on the engine 1, and the low-power low-noise sound insulation cabin type air cooling power supply stops working. And further, the fan monitoring and controlling functions of the low-power low-noise sound insulation cabin type air cooling power supply are realized.
The utility model relates to a cabin formula forced air cooling power supply fan monitor control system gives sound insulation of miniwatt low noise, the specially adapted security requires high, the reliability requires high miniwatt low noise cabin formula forced air cooling diesel generating set field that gives sound insulation.
