What is the difference between emergency power supply and standby power supply? What does it have to do with the emergency power supply system?
The reliability of the emergency power supply is not very high. It is only required to supply power when the main or standby power is lost. Put into operation a few seconds, the main standby power supply emergency power supply permit is lost, so when the emergency load conditions can generally be used in quick start diesel generator, the load is small, can also be used in DC power inverter. If no power outage is required at any time, that is, UPS (uninterruptible power supply), normal AC power supply, the accident from the electronic switching device to the DC inverter power supply, power switching time in a few delicate level.
Emergency power supplies are used in emergency situations, i.e., when other power supplies are not available, including standby power supplies.Standby power is the main power supply, the frequently used power supply is called the main power supply. When the main power supply needs to be repaired or damaged, the standby power supply is used.Emergency power supply system only applies emergency power supply, the emergency power supply system and the main power supply system is different, than the main power supply system is simple, that is, the power supply range is much smaller. The power supply range between the alternate power supply and the main power supply is the same.
The emergency power supply to emergency power supply system is the emergency power supply system, including switch cabinet and cable protection.
Emergency power is lost in the main power supply and stand-by power supply situation, in order to protect the safety of person and equipment settings, general requirements of the power supply is independent of external power supply, so that the loss of power in the external power failure, emergency power supply is still running;
The standby power supply is relative to the main power supply and requires the backup power to be supplied from an independent power source relative to the main power supply. When the main power supply disappears, the standby power supply shall be automatically or manually operated to ensure the reliability of the power supply;
