A fire emergency multifunctional power supply system

Abstract

The invention discloses a fire emergency multifunctional power system. The system mainly comprises an LCD liquid crystal display, an LCD display menu switching key, a branch output circuit breaker, a main power input circuit breaker, a battery pack positive / negative electrode input circuit breaker, a forced emergency starting switch, a starting / reset button, a manual / automatic button, a PE connector bar and an output neutral wire connector bar. When commercial power is normal, an output of an emergency power supply is provided by the commercial power and a charger charges a storage battery; when the supply of the commercial power is stopped or the voltage of the commercial power is lower than 180V, the emergency power supply works in an emergency state. The system can completely protect a load and ensure normal operation during power failure, and is excellent in performance and high in reliability; and the system can display a main power voltage, a battery voltage, an output voltage, an output load current and a fault type, is simple to operate and convenient to maintain, has the functions of output short circuit protection and over-load and over-temperature protection as well as a function of battery over-discharging protection, and not only has a sound fault alarming function but also can indicate the fault type.

Description

technical field [0001] The invention relates to the technical field of emergency power supply, in particular to a fire emergency multifunctional power supply system. Background technique [0002] The special emergency power supply system for fire emergency lamps is an indispensable power supply for sign lamps and lighting lamps in case of fire or other emergency situations in buildings. With the improvement of building fire protection level, especially the increase of high-rise buildings, emergency power supply has developed rapidly. [0003] At present, most of the special emergency power supply systems for fire emergency lighting used in buildings are independent fire emergency lighting and evacuation indication systems with their own power supplies. The battery life of the power supply is limited, generally two to three years. The capacity gradually decreases, or even fails. In addition, in order to ensure the normal operation of the battery, the fire emergency lighting...

Problems solved by technology

[0003] At present, most of the special emergency power supply systems for fire emergency lighting used in buildings are independent fire emergency lighting and evacuation indication systems with their own power supplies. The battery life of the power supply is limited, generally two to three years. The capacity gradually decreases, or even fails

In addition, in order to ensure the normal operation of the battery, the fire emergency lighting power supply generally provides a manual detection function, which requires manual inspection one by one, which is time-consuming and labor-intensive. Moreover, the cost of replacing the battery remains high. exclude

Once a disaster occurs, the lighting and evacuation indication system cannot work normally, or the lighting duration cannot meet the specified standards, which will bring serious hidden dangers to personnel evacuation and disaster relief work

That is to say, the current special emergency power supply for fire emergency lamps has the problem of not being able to detect the power state in real time and find faults, resulting in the shortcomings of being unable to guarantee normal use in emergency use, unable to meet the actual needs of fire emergency, and there is a certain degree of safety.
