Emergency power supply device circuit protection system

Abstract

The invention provides an emergency power supply device circuit protection system which comprises a circuit protection module, a circuit detection module, a power supply module, a control module and a signal module. The power supply module is connected with the control module. The control module is connected with the signal module. The control module is provided with a fixed program. A signal is converted into a circuit identifiable signal through the signal module, and then is transmitted into the circuit detection module. The circuit detection module detects a circuit, converts detection data through the signal module, and transmits the data to the control module. If the detection data are not in the range set by the control module, the control module turns on the operation of the circuit protection module. The circuit protection module is connected with the power supply module to control the operation of the power supply module. According to the invention, an emergency power supply device can be effectively protected in real time in the case of voltage and current instability.

Description

technical field [0001] The invention belongs to the technical field of power supply protection, and in particular relates to a circuit protection system for emergency power supply equipment. Background technique [0002] The emergency power supply is mainly used to provide centralized power supply for emergency lighting and other lamps (including high-pressure gas discharge lamps such as metal halide lamps and sodium lamps) in case of fire in buildings or other emergency situations. Therefore, it is widely used in power or emergency lighting in various buildings, medical systems, transportation systems, financial systems, institutions, shopping malls, schools, docks, squares and other places. In the event of a fire, the EPS system will receive the fire signal and automatically switch to the emergency state - the inverter power supply. This will continue to provide power to the electrical device. [0003] Patent No.: ZL2006201686245.5 is a patented product named "Rapid Emer...

AI Technical Summary

Problems solved by technology

However, there are still imperfections: the device only realizes automatic circuit switching when the working power supply disappears or nearly disappears (extremely low voltage). , waveform distortion, network trends and other phenomena are not enough attention

[0004] To sum up, there is a need for a better protection system to protect the circuit of the emergency power supply equipment to prevent damage to the emergency power supply equipment in the case of normal voltage instability or current short circuit, resulting in failure of the emergency power supply equipment during power outages. Normal use
