Abstract

The invention discloses an emergency power supply system with an output time-division switching function. The emergency power supply system comprises commercial power AC, an input breaker QFA, a charger U, a storage battery GB, an inverter UI, an isolation transformer T, a first contactor KM1, a second contactor KM2, and an intelligent power distribution module. The commercial power AC is connected with the input breaker QFA. The output of the input breaker QFA is divided into two paths: one path is connected with one end of the first contactor KM1, the other end of the first contactor KM1 is connected with the intelligent power distribution module, and the other path is connected with the input end of the charger U. The output end of the charger U is connected with a node between the storage battery GB and the inverter UI. The inverter UI is connected with one end of the second contactor KM2 through the isolation transformer T. The system has a battery monitoring function, is capable of dynamically prolonging the standby time of loads according to actual conditions of the loads, and meets the demand that different loads need different emergency time.

Description

technical field [0001] The invention belongs to the field of emergency power supply, and in particular relates to an emergency power supply system with output time-sharing switching function. Background technique [0002] As a backup power supply, emergency power supply has been widely used in subways, shopping malls, hospitals, government affairs centers, high-rise buildings and other places. The power distribution of buildings is becoming more and more abundant, and the demand for emergency power distribution is also becoming more and more diversified. Different loads have different time requirements for emergency power supply. For example, for fire-fighting equipment in buildings, GB16806-2006 "Fire-fighting Linkage Control System" stipulates that the emergency power supply of fire-fighting equipment connected to fire-fighting pumps, sprinkler pumps and other fire-fighting equipment should not be less than 3 hours under full load conditions. , and not less than the nomin...
