Emergency power supply is translated from English by the Emergency Power Supply, referred to as EPS, which is composed of charger, inverter, battery, isolation transformer, switch and other devices to invert DC power into AC power for emergency power supply. It can automatically switch to the backup power supply when the main power supply fails. It combines the advantages of uninterruptible power supply UPS and emergency generator set to provide reliable power guarantee in case of power failure or emergency.
The main purpose of emergency power supply is to provide stable and reliable power for important equipment in case of power failure or emergency, so as to ensure the normal operation of equipment. It is widely used in chemical industry, pipe gallery, rail transit, highway construction and other fields to provide emergency power support for key equipment and facilities. The emergency power supply has the advantages of high efficiency, reliability, and intelligence. It can quickly switch to the backup power supply in a short time and ensure the continuity of power supply. It is one of the important equipment to ensure the normal operation of important equipment and facilities, especially in the case of power failure or emergency.
Article 3.2.9 of the GB51348-2019 "Civil Building Electrical Design Standard" stipulates that for the especially important load in the first-class load, the power supply shall meet the following requirements: in addition to the dual power supply, emergency power supply shall be added; The emergency power supply circuit shall be self-contained and other loads shall not be connected to the emergency power supply circuit. The switching time of emergency power supply shall meet the requirements of equipment allowing interruption of power supply. Power supply time of emergency power supply, the requirements for the longest continuous operation time of electrical equipment shall be met; for the ports on the end distribution box changeover switch of the particularly important load in the first load, power monitoring and fault alarm shall be set.

1, original technology: into a number of independent research and development of current and voltage PI acquisition technology, as well as BAS and FAS linkage, to ensure the stability and safety of the system.
2. Module plugging and unplugging: with unique modular design, each module can be quickly plugged and interchanged, which is convenient for system testing, operation and maintenance, and improves operation efficiency.
3. Fast switching: through PI acquisition, the mains power is quickly switched to the emergency standby power supply within 5 milliseconds to ensure the rapid and stable power supply of load equipment.
4. Intelligent monitoring: With advanced intelligent monitoring function, it can monitor the power supply running status in real time, provide users with accurate running data, and facilitate the maintenance of the power supply system.

Lighting EPS power supply device
·The rated output power shall not be less than 1.3 times the total capacity of the connected emergency lighting load.
Electric power equipment EPS power supply device
·When the EPS power supply unit has multiple motors and all start
EPS capacity = 1.05 × (the sum of the motor power directly started × the sum of the motor power started by 5 stars and triangle × 3 the motor power value started by variable frequency × 1.1)
· When the EPS power supply unit has multiple motors and they are not started at the same time
EPS capacity = 1.05 × (the sum of the power of each motor, the power of the single motor with the largest direct starting capacity, X7 stars, the power of the single motor with the largest triangular starting capacity, × 3 the power of the motor with the largest variable frequency starting capacity, × 1.1)
The above motor work must also meet the following conditions:
a) The maximum single motor power for direct start is less than 1/7 of the EPS usable capacity;
B) The maximum power of a single motor for star-delta starting is less than 1/3 of the usable capacity of EPS;
c) The maximum single motor power for variable frequency start is less than 9/10 of the EPS usable capacity;
d) Adjust the capacity of EPS according to the maximum number in the above conditions to meet the working conditions of the motor. At the same time, the starting sequence of the motor shall be the first to start directly, followed by the star-delta starting, and finally the variable frequency starting.
