Multi-system modularization emergency power supply (EPS)

Abstract

Provided in the invention is a multi-system modularization emergency power supply (EPS), which is characterized in that: the EPS is composed of an intelligent monitoring module, a pluggable EPS inversion module, emergent conversion modules and a storage battery; the intelligent monitoring module, the pluggable EPS inversion module, and the emergent conversion modules are arranged and installed in a same equipment cabinet respectively and independently to form a multi-system modularization EPD; and the storage battery of the EPS is placed in another equipment cabinet. According to the invention, advantages of the EPS are as follows: the EPS is formed by the emergent conversion module and a plurality of EPS inversion modules with rated capacities and a hot plugging mode is employed to carry out extension randomly; meanwhile, four kinds of power supply mode systems including a three-phase-input and three-phase-output mode system, a three-phase-input and single-phase-output mode system, a single-phase-input and single-phase-output mode system, and a single-phase-input and three-phase-output mode system are constructed; all EPS inversion modules share an built-in battery group and a battery redundant structure can also be formed; power supply balance distribution processing is carried out on the output terminal and the input terminal; and moreover, the whole appearance of the EPS is in a layered structure; and the EPS with a small volume is convenient for moving, transportation and placing.

Description

technical field [0001] The invention belongs to the field of emergency power supply EPS, in particular to a multi-system modularized EPS (Emergency Power Supply). Background technique [0002] Such as figure 1 As shown, the EPS emergency power supply currently used in the market is an independent complete machine, which adopts the stand-alone working mode. When using it, it is necessary to select different power according to the load of the user's power supply equipment and the input and output parameter requirements of the power supply mode. 1. For EPS emergency power supplies with different power supply phases, when the EPS is faulty and damaged, the power must be cut off for maintenance. In this way, the emergency power supply mode will lose its effect during the maintenance period, and the emergency power supply for user equipment loads will cause serious safety hazards, and users will It is very inconvenient to expand the capacity of EPS emergency power supply.
