Abstract

The invention discloses an emergency power supply (EPS) having a modular structure. The EPS comprises a battery pack, a charging system, an inversion system, a change-over switch module, a feeder line detection module, a battery inspection tour module and a monitoring device; the battery pack comprises n single batteries, the charging system comprises n charging modules, and the inversion system comprises n inversion modules; and an AC input is simultaneously accessed to input ends of the n charging modules, an output end of each charging module is connected to a charging input end of one battery, an output end of each single battery is connected to an input end of one inversion module, output ends of the n inversion modules are simultaneously accessed to an input end of the change-over switch module, and an output end of the change-over switch module is connected with a load. The emergency power supply (EPS), provided in the invention, having the modular structure adopts modular design, and can conveniently achieve maintenance of the EPS; and the emergency power supply (EPS) having the modular structure improves stability of the EPS, and solves the problems of the large failure probability and maintenance inconvenience of a traditional EPS.

Description

technical field [0001] The invention relates to a modular structure EPS (Emergency Power Supply) emergency power supply, which belongs to the emergency power supply technology. Background technique [0002] With the rapid development of the national economy, urban traffic is becoming more and more severe. In order to alleviate the pressure on urban traffic, the first-tier and second-tier cities in China are basically actively building rail transit infrastructure. In order to ensure the safety of subway passengers, the safe and normal operation of emergency lighting equipment at each station is particularly important. When the mains at the station fails, there must be an EPS emergency power supply that can supply power to the lighting fixtures in an emergency to ensure that passengers can evacuate the station in a timely and effective manner. , so as not to cause a stampede accident, which requires that the emergency power supply should have higher stability. Avoid the EPS e...
