UPS power emergency vehicle application and working mode
Huabao Golden Samurai UPS power supply 2020.6.20
The emergency power supply vehicle is suitable for all-weather outdoor operations. It has the characteristics of stable and reliable overall performance, easy operation, low noise, good emission, and good maintainability. It can well meet the needs of outdoor operations and emergency power supply. The use of mobile emergency UPS uninterruptible power supplies with storage batteries for energy storage to ensure power supply will play an active and important role. It is suitable for various power accident repairs, emergency treatment, civil disaster relief and large-scale public event venues and other important places with high power supply requirements.
The application of the mobile UPS power supply vehicle, when the utility power fails to recover in a short time, the UPS power supply can be used to realize the seamless connection of power supply in real time. Therefore, it is ensured that the operating equipment is switched from the mains power supply to the UPS power supply, which ensures the uninterrupted operation of the equipment and reduces the impact of accidental power outages on production and life to zero.
The vehicle-mounted dedicated UPS uninterrupted power supply, the vehicle-mounted dedicated battery pack with good anti-vibration and anti-vibration performance, and input and output power distribution. The whole system uses the most mature UPS uninterrupted power supply technology and low-voltage output power distribution technology to form an integrated mobile power supply equipment. Its performance is reliable, operation is convenient, and maintenance is simple. The whole vehicle has the advantages of stable power supply, low harmonics, safety and reliability, and long service life.
When emergency power supply is needed, the vehicle can be connected to the power supply line of the power user to achieve emergency power supply. When the power grid is suddenly cut off, the system will automatically switch to emergency power supply seamlessly, ensuring long-term power supply. When the power grid is restored, the vehicle system will automatically switch back to the mains power supply mode.
UPS emergency power vehicle working mode
1) When the mobile UPS vehicle is connected to the electricity market, the mobile UPS vehicle is bypassed from the mains via the STS to provide power to the load and charge the battery. During charging, the battery is charged according to the type and requirements of the battery, and the charging current and voltage are controlled to ensure that the battery is quickly charged under safe and reliable conditions.
2) After the mains power fails, the STS is closed, and the inverter in the grid-connected output state works. The battery discharges and outputs through the inverter, seamlessly replacing the mains supply load, and the inverter provides uninterrupted voltage and starts at the same time Oil machine.
3 After the diesel generator runs for 3-8 minutes and stabilizes, the diesel generator supplies power to the rectifier, and then provides power to the load through the inverter, while charging the battery.
4) When the mains power is re-applied, the inverter will track the mains, automatically switch the generator input power back to the mains operation, and send a stop signal to the generator at the same time, because the battery pack is always in a seamless output state and connected to the grid To ensure zero switching time.
Summary: UPS power trucks are used for various activities that require uninterrupted power supply. They are used in conjunction with mains and generator cars, so that when the mains power is out of power, the on-line UPS equipment is used for zero-time conversion. Vehicles must operate all-weather under conditions of heavy rain, high temperature, cold, high altitude, etc.; they can drive safely on muddy roads and roads with many curves.
