1 .standby power supply is relative to the main power supply, requiring standby power supply from the main power supply is relatively independent of the power supply. When the main power supply disappears, the backup power supply should be able to automatically or manually cast to ensure the reliability of electricity;
2 .emergency power supply is in the main power supply and standby power are gone, in order to protect the personal and equipment safe settings of the power, the general requirements of the power supply independent of the external power supply, so that the power failure in the external power grid, the emergency power supply can continue run;
3 .will be emergency power supply to the need for the power supply to the power supply system, is the emergency power supply system, including switchgear and cable, protection.
4. to explain is: does not require the reliability of emergency power is very high, only in the main and standby power supply can be lost in the case of power can be, usually can be out of the box. Emergency power supply allows the main and standby power supply is lost after a few seconds into the run, so when the emergency load situation can generally use the fast start diesel generator sets, the load is small, you can also use DC inverter power supply. If you can not power off any time, that is, non-power supply (UPS), the normal AC power supply, the accident by the electronic switching device for DC inverter power supply, power switching time in several subtle levels.
Summary: Emergency power is used in an emergency situation, that is, in the case of other power can not be used, including standby power. The standby power supply corresponds to the mains supply, and 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 is only applicable to emergency power supply, emergency power supply system and the main power supply system is not the same, than the main power supply system is simple, that is, a much smaller power supply range. The power supply range for the standby and mains is the same.log on to our official website for more :http://www.linsheng.com/
