UPS Power Changchun Hongbao Manufacturer Before the HBG series UPS power installation, users must input and output power distribution for U P s power. Hongbao Changchun Hongbao manufacturers will provide users with a full set of UPS power installation requirements and precautions. Only after this requirement, the UPS is uninterruptible power supply to the power supply system will work. The company’s technicians can send relevant data to the user according to the actual situation of UPS uninterrupted power supplies to be installed, so that users should be constructed in this request.
1. Use units for the UPS uninterruptible power supply. The fluctuations are generally smaller than the allowed market power source nominal of the UPS uninterruptible power supply, such as Hongbao HBG series UPS uninterruptible power supply nominal allows the mains input voltage fluctuations. At 220V + 20%, then this item may require the user to fluctuate in + 15%, which facilitates the normal operation of the UPS uninterruptible power supply; the zero voltage generally requires less than 1.5V without the load, with a full load of less than 2V, Engineers can also propose this value according to the on-site situation and load requirements. Online UPS-HBG series. The operation is powerful, and it can detect accurately and quickly, control the various acts of the UPS to ensure high reliability of the product. With a unique AC-DC conversion circuit, the output current and output voltage of the mains are detected, and the current waveform of the input power supply is consistent with the voltage waveform phase by high frequency pulse width modulator to achieve a high input power factor greater than 95%. . Under normal circumstances, the main electricity is passed through the AC-DC circuit to obtain DCBus DC voltage, and then convert DCBUS to 220V AC output by the inverter. The power supply used by all loads is regulated, and the pure sinusoidal. Wave power supply.
2, UPS uninterruptible power supply In order to eliminate common mode interference, zero, the fire line is added to the ground, zero, the fire is currently current, which may cause zero, the fire on the fire is not equal, so that the broken circuit with leakage Slap. Then the UPS uninterruptible power supply front level and load circuit cannot be loaded with leakage protection, so as not to cause the UPS power supply and its load unexpected power. It should be pointed out here that the use of units in the UPS uninterrupted power supply is to ensure the safe operation of the computer and other equipment, rather than protecting personnel security, so it should not bring electricity components such as sockets in the line. Frequently plugged, opening and closing.
3. In order to eliminate interference, most UPS uninterrupted power supply input neutral lines are isolated or after choke, so the UPS uninterruptible power supply cannot be output when doing UPS uninterruptible power supply (ie The zero line of the load is connected to the spline busbar of the input distribution. Users can connect the UPS uninterruptible power output (load) cable to a separate zero line. Hongbao HBG series UPS uninterruptible power supply can be discharged from the output zero line with the output (load) zero line in the UPS uninterruptible power supply.
4, the UPS uninterruptible power input circuit breaker is the disconnection of the power input power supply to the UPS uninterruptible power supply separately, so the UPS uninterruptible power input circuit breaker should not receive other power equipment, so as not to affect the UPS uninterrupted Normal turnover of the power input. Here, some users require the UPS power supply after the market is charged, the UPS power supply has long time, so that the capacity of the external long delay battery with the UPS power supply will be large, in order to ensure this part External batteries can have sufficient charging current (generally 10% of the total AH number of external batteries), Hongbao will give the UPS power supply additional external long delay battery charger, this charger AC input power supply and UPS The input power of the power supply simultaneously offers, in order to ensure that the external charger is charged with the external battery when there is a market, the battery is discharged to the UPS power inverter immediately. Therefore, the AC input electrical input of this charger is to be electrically connected to the UPS power supply to the next mouth of the same circuit breaker.
5. When the input and output circuit breakers are selected for the UPS power supply, the rated voltage nominal of the circuit breaker should be required to match the rated input output voltage of the UPS power supply, such as single-in-one UPS power supply optional single (or N + 1, or The two-pole) rated voltage is an AC220V or 250V circuit breaker, and the three-in-three out of the UPS selective triode (or N + 3, or the quadrupole) rated voltage is an AC380V or 415V circuit breaker. Pay attention to the rated breaking ability of the circuit breaker to comply with Hongbao’s requirements, and generally small UPS power is 6ka or 10kA, and large and medium UPS power supplies are required to 30kA.
6. The connection between the UPS power supply and the external long delay battery should not be too long, otherwise the pressure drop in the battery connection is too large. In addition, the use of orders tend to pay attention to the ambient temperature and humidity of the UPS power supply host, and the battery is placed together with the UPS power host to make the battery have achieved a good working environment.
7, Hongbao Company recommends that the unit is set to the UPS power supply and its load separately sets the power supply to the UPS power supply and its protected loads. This power distribution cabinet should comply with national standards.
